I think I've accomplished what you are looking for. Take a look at
http://www.jatosoft.com/cftest/hello.html.

There are 3 files used to produce that output: hello.html, hello.php3, and
themessage.php3.
hello.html uses the same source as your hello.html did.

The file "hello.php3" looks like this:

<?php
$theDate = gmdate("D, d M Y H:i:s");
header("type='application/x-javascript' reset='no'");
header("name='expires' value='$theDate'");
header("name='pragma' value='no-cache'");

include("themessage.php3"); //This is the file where input is specified,
using variable $theInput

if (!$theInput)
{
$theInput = "No Message specified."; //If input is not found, we
should let the user know.
}

$theInput = eregi_replace("10", "\n", $theInput);
$theInput = eregi_replace("13", "\n", $theInput); //Makes sure that all
carriage returns are \n
$theInput = addslashes($theInput); //This function puts slashes in front of
quotes and the like
print ("document.write(\"$theInput\")");
?>

The file themessage.php3 looks like this:

<?php $theInput="Hello World"; ?>

I've seperated the script and the message into two files for ease of use -
when modifying the message, you don't have to worry about screwing with the
rest of your code. However, you could easily just change the include() line
in hello.php3 to read

$theInput = "Hello World";

and dispose of themessage.php3 altoghether. You can also use a HTTP GET to
specify the message - for example, the code of hello.html would look like this:

<-- snip
<script src="http://www.jatosoft.com/cftest/hello.php3?theInput=Hello
World"></script>
<--end snip

Again, you would dispose of the include() line in hello.php3 if you used
this method.

Let me know if this solution works for you.

Mark,

Think of the millions of Geocities-type personal websites out there,
built on static HTML with no provisions for processing even CGI scripts,
and you can offer those sites a fully-functional dynamic web application
in one line of code: <script
src="http://mydomain.com/myapp.php3"></script>.

We're basically being a low-end ASP (Application Service Provider).
Right now, we've got our little non-Java Fuselet Chat application, and
our Subliminal Flasher application (both can be seen at
http://fuselets.com), which are free, paid for by banner ads, and can be
put on any website in the world with one line of code. But think of
full-blown discussion forums, or intranets, or e-commerce solutions,
that you would host and rent to others for 10 or 20 bucks a month.

Our back-end is currently running on ColdFusion, but we want to build
some Fuselets (and have some of you build some Fuselets) that run on
PHP. We're not trying to mudge PHP into looking like ColdFusion; we're
trying to replace ColdFusion with PHP, so that we can scale up to higher
volumes on cheaper hardware and software.

Does that help?

PHP is quite - what's the term - all-over-the-place at the moment, so just
check your ISPs server to see if they have it.

>Are there any security issues with calling rows by their id?

With the risk of sounding like a complete moron, define "security issues".

In the end it's all up to what your code allows the user to do. If you have
code that allows the user to delete an entry only by doing
"delete_entry.php3?entry_id=123" then yes, there are security risks. But not
because you're using an auto_incrementing id field, it's because you're not
checking if the user doing the delete is allowed to.

As long as you yourself write all the code that accesses the databases it's
up to you to make sure that there's no security issues. If others are to
mess with your databases it's a different story and I'm not good enough at
MySQL security to tell you what to do about it.

if the id is the only property which selects a row, anyone can look whats

you might wan't to use sessions to hide the data.

I try to configure and run php, apache and MySql together.

Compilation and installation goes without any problem. But when enabling php in httpd.conf file (LoadModule), apache terminates without any messages.

I have tried to run gdb on apache, but I'm not familiar with the apache source code.

Having worked with quite a few print, and web, designers, there are the good ones in visual design, who suck at implemention, the good implemementors who suck at concept.... But in order to stay gainfully employed, they _cannot_ just wave a sharpie at a board and make things happen, there has to be some implementation, somewhere. The programs that tend to *appeal* most to designers are the ones that make that easiest... and it doesn't have _anything_ to do with syntax, (absurd debates about code "cleanliness" notwithstanding), or variable passing. As soon as you say "variable passing" to a designer, the game is over. They don't want to control logic, they want to control form, and function. They don't do logic, they do presentation.

So: They will, for the most part, look at a "template library" with disdain for the _exact_ same reasons they look at raw PHP with disdain. It has nothing to do with syntax, or tags, or simplicity. Most designers don't even like working in raw postscript, or raw PHP, or _even raw HTML_. They don't give a hoot what the code "looks" like, they'd rather not know, or care. HTML code is _too_ complex for what they want to do, let alone HTML coded with PHP (or even a template library to simplify the coding). How many print designers ask for a postscript library to simplify coding their print design? Few to none. Some used to sweat over their Compugraphic, every character... they're gone now. Designer-programmers are a transitional phase, not an end direction.

Take a look at how they use Javascript. Javascript is used by designers in downloadable "components", which they then use to build their web pages. Most couldn't even figure out *how* to write a rollover, which is why Fireworks sells like hotcakes. They don't give a hoot if the code looks pretty, or ugly, they care what the _product_ looks like. The same arguments plagued Javascript: "can't we re-write it so they'll use it?" No. You cannot write a PHP language, or any language, that all designers will be happy with. There are vary few who even know how to code postscript for their print work, let alone control postscript _logic_. They want to easily position elements, indicate what it does, and go from there. The don't care what the code looks like. So no matter how simple you make the code, you're going in the wrong direction. They don't want simple code, they want _no_ code.

It helps, I think, to work in Database UI design.... the main package pushing the edge on what visual design meshed with coding should "be like" is filemaker, where structures like loops have a clear "Loop... end Loop" syntax. The visual appearance, like most current HTML design packages, is not even _part_ of the logic. As soon as you expect a designer to follow a prescribed syntax, you're lost in the woods again, so the FM philosophy was to make the syntax as simple as possible... and you know what? In the filemaker UI world, the dumbed down "template interface" proposed is _too advanced_. It's "programming", and FM programmers make out like bandits, because the concept of a *variable* is just too advanced for most non-programmers. Really.

So we're not even really talking about most designers, we're talking about the learning curve for designer-implementors, whether or not the syntax itself leads to easy understanding. Amusingly enough, I found most of the posted examples of the Template design to be just as obtuse, and cryptic, as PHP is. is a looping array? Okay, go ask a web designer what a looped array is. :-)

At one site I'm working at, a designer-implementer (can code raw HTML if forced) once said to me: "I don't do coding. I design. If I have to write HTML codes, I'll call a programmer. I control how the page looks, not the code to make it look that way." That stuck with me as a reminder that anything I did to try to make their coding easier was for naught, they don't want to do any of the code in the first place.

Okay, that all being said, I've been looking at the examples of how this is supposed to be easier coding, and, quite frankly, it looks like the templates are supposed to fix a problem with obtuse PHP _coding_, with bad programming. Not because the designers "can't work around the code", but because of poor choices in the PHP programming *itself*. There was a complex "for" loop initialization that could have easily been a "while", happily cutting down on what somebody has to learn to read the code... if you want a designer to read your code, for god's sake, don't use contructs that *they can't parse*.

That's not a PHP issue, that's a general UI issue, and you can't fix it by the syntax, as the syntax isn't the problem in the _first place_. Never has been. I've seen human parsable assembly-destined programs, because it used good _coding_, which had nothing to do with the syntax of the language, it had everything to do with the usage.

Is programmer ego just too big to get over using "i++;", or can they bother to write "$loopcounter = $loopcounter +1;"? Do they need to add *yet another* tool, because they can't write web-designer-readable code, so they have to hide their code? Is the template idea to maintain poorly human-readable code?

That's what it looks like to me. If you want to hide the code, hide it, but you don't have to justify it as some sort of "advancement in designer templates", it's not. It's sending variables to hidden code, so the code can stay ugly and unreadable, cutting down on code commenting and formatting time.

Here's how we do it: We use includes for the code (oh my gosh, a file read? get over it. It's web pages. Do you limit the amount of gifs on the page to keep you file reads down?), we have them state their variables. That's all they need, no PHP template library, no ongoing custom coding, just enough knowledge for them to know how to update:

<? $headline = "This is where the Headline Goes" ; $pagetitle = "This is where the Title Goes" ; ?>

And so on. The hand coders already know how to use an = sign, so they have to learn "<?","?>" "$" and ";". Four tags/tokens, much, much, less that the various template ideas (retagging a language does not make it easier to use). When they need to revise or update their code, it's simple, because the _coding_ is done with them in mind.

So when designer-implementors have their code blocks built for things like the standard roll-over-contents bar, we make that an include, as well. So, they have to take a "massive leap of faith":

<? $headline = "This is where the Headline Goes" ; $pagetitle = "This is where the Title Goes" ; include "sales_html_header.inc" ; ?>

That's it. Our designers prefer working this way, as it's much the same as Quark templates or master pages, where they take stock elements for each page, and customize if needed. They make the template, it gets put into PHP form, they add as needed...

Design pages _first_, then coding comes in. I think one of the bigger problems is that far too many companies have coders building logic first (bottom up design), not appearance first (top down). Perhaps the coders don't realize that the product of the web is not the code, but the *appearance*. So now there are people trying to fix, in essence, workflow problems, without realizing that the problem isn't that HTML coders are "breaking" their PHP, but that their HTML coders are even exposed to it in the *first* place. It's not that a better code syntax will keep web designers from making errors, they will make errors if exposed to *any* code. So keep it away from them!. They design the page appearances, then coder implement for it.

This works for small scale (<50) page sites, but what about larger sites? The designers do _even less_. Their job is look and feel, not content. Content folks don't do look and feel, they do data. So designers build the look and feel, and pass that to programming. Programming then builds the dynamic pages, which access the content databases. Content folks never see the HTML or PHP, they *shouldn't have to*. Design folks never see PHP or the content, they *shouldn't have to*. The programmers never see the content, they have to work around the HTML. Content plugs their data into the content databases, free of concerns about the coding, or the look and feel.

So the knowledgable folks work in their tasks, and only their tasks. Problem solved. Nobody needs to try to teach a new syntax (XML? XSL? Maybe when it's in Dreamweaver, Pagemill, Frontpage, etc.), learn a new syntax, etc.

So where does this leave the debate? Well, I think the template idea works on one level: Using *code* templates like PHPlib has made life a lot easier for new PHP coders. Building code templates for beginning PHP coders goes a long way to helping design-implementors out. (HTMLlib?) Maybe taking the best of the html functions and putting them into PHP is a good idea (I'm surprised that there is such a small section of the manual for ht(ml/tp) functions, considering that it's the main use of PHP). Simpler construct usage is always good (while, rather than for::), and if there are more concise ways of formulating a contstuct (control, functions) it's good to see them rolled into PHP (in_array rocks.).

But no function, no syntax, can fix poor coding. It's easy to write obsfusicated code in every language, no? That means that it's *easy to use template language variants to be unusable for designers*. The syntax is not the problem.

PHP4 has support for COM. It is about to go into its first RC, and hopefully be out soon.

I am currently hacking on an OBRit-based CORBA interface for PHP4. I have done all my work in CORBA in C++ before, so am having some time getting the C language mapping for DII down, but am getting close.

Er.... is not having this in HTML, or even a text document, a form of dreadful irony?

That what can be done in simple forms, must then be overlaid with excessive, and complex, structures, only to accomplish what can be done with much less effort? :-)

To paraphrase your own text: ' But where do you draw the line with template functionality? From a technical viewpoint, variable substitution can be done in the html, and all other logic should be kept in other files. On the other hand, designers need flexibility to control the layout of the html. Each time they must tap the shoulder of the programmer and request some changes in the html, this requires another loop in the development cycle. In an application where more web pages are continuously created and manipulated, the programmer should not be needed once the code is in place. '

So, the programmer sticks the logic in an include (or require), the HTML folks assign values to the variables....the coders mess with the logic, not the html, the html folks mess with the HTML (as needed).

What's missing from this?

With your method, the programmer must change the PHP logic (what is included) for each template. How is this scalable to manage many templates? You are no longer separating form (presentation) from content.

The way we proposed to make this work: the programmer passes content to the template, the designer controls the presentation of this content, and they control ONLY the presentation. The small set of functionality in the template spec accomplishes just that. The designer can make templates to their hearts desire without the need to change the PHP code underneath. Then later if you want to update the PHP code, there is only one set of code to update, not a whole slew of differing PHP code for each template.

Not at all. There is no limit to how many HTML pages can call the same logic block. If the logic _features_ change, then in both of our methods, the programmers have to rework the pages. I'll give you an example: The server- wide credit card validation logic is one, and only one, file. It never has to be duplicated, never seen by the website designers. The most a designer has to do is add an hidden form variable, or build an HREF on a page, (both are things they're fairly knowledgeable about) and on the next page, know the syntax for an include, and decide where to put the result. So adding dynamic content means they need to know all of *two* statements.

This would mean that my designers do, indeed, have to know the following (and they do):

Logic: <? include "generic_logic.inc" ?>

Presentation: <? echo $var ?>

Hey, Rasmus/Zeev et al: Can we get a variable function equivalent to echo? As in: <? #$var ?> being the same as: <? echo $var ?>

> The designer can make > templates to their hearts desire without the need to change the PHP code > underneath.

Exactly. They don't even need to learn a whole new language, beyond an include, and, maybe, an echo.

> Then later if you want to update the PHP code, there is only > one set of code to update, not a whole slew of differing PHP code for > each template.

So don't build different code for each web page! That doesn't require a new syntax, that requires building generalized logic. We are rapidly spiralling from the newish template debate into the old monolithic vs. OO debate... and your code is basically _an_ OO set of generalized logic, which, for some reason, you are passing using an new syntax.

Take a look at php4.

<? echo $var ?> = <?=$var?>

Once upon a time, I thought foreach() would be the main reason I wanted to switch to php4. So far I haven't used foreach once, but I have tons of things printed with <?="whatever"?>.

Yes, I know it is still in beta, but as someone once said on the list, it is open source and in beta, so it is probably better debugged than most M$ products when they are first released.

All my new development is done with php4. I haven't actually released a site to the public running on php4, but I have three in development, and have no problem with the idea of releasing them before the final release of php4.

You need to add php3 to your DirectoryIndex statement in httpd.conf, or possibly srm.conf, wherever your appace configuration is stored.

Hi!

I'm new to PHP so please forgive me lack of deep understanding of how it works. My questions are:

1. I want to make a questionaire. I want it to work this way: - 1. On first page user sees a form with some fields to fill in. It's validated in browser with JavaScript. It then submits form data to second page. [This step works OK] - 2. On second page user sees what he entered in nicely formatted HTML and is asked to confirm correctness of what he entered. Up to this moment it is done. Currently all form data is stored in variables like $name, $address etc. which is very convenient. Now I need to either pass this data to third page when PHP script stores this data in database or somehow ask user for confirmation and proceed on the same page. Problem is: I don' t know how to make variables persistent over several pages so the script on third page can use them OR how to ask user for confirmation and proceed on the same page.

One possible solution is to store all data in system variable and read it back later but it would be terribly inefficient and complicated.

I hope I made it clear enough :-) If not, please let me know! Any help would be appreciated. Hint: I'm not stupid, I just don't know how PHP works ;-)

Second question is related to this 'hint':

2. Where can I found PHP *tutorial*. I have read most of php manual (which is more like specification than manual) and I have seen tons of examples (downloaded lots of them :-). But what I couldn't find is The Tutorial that would explain the way how PHP works. I need understanding of PHP's way of organizing things. To be honest, I was surprised that it's not available from php.net.

Thanks for any help, Max

You can do one of three things:

First, pass the data via the URL... this works something like: final_page.php?name=Joe&last_name=blow&address=nowhereland&.....

Secondly, you can store the data in a form in hidden fields then if he click's ok, just submit the form.

Third, PHP supports sessions, in which you can have certain variables that are valid for as many pages as you require.

I'm new to PHP so please forgive me lack of deep understanding of how it works. My questions are:

One possible solution is to store all data in system variable and read it back later but it would be terribly inefficient and complicated.

I hope I made it clear enough :-) If not, please let me know! Any help would be appreciated. Hint: I'm not stupid, I just don't know how PHP works ;-)

Second question is related to this 'hint':

Thanks for any help, Max

on the first page you did something like this in your forms, no? <input type=text name=address> when a form with this text box is passed to a php page the variable $address will carry what the user entered. On the next page you probably showed the value like this: <input type=text name=address value=<? print "$address"; ?> > If you want the user to verify you could: include a hidden form field like: <input type=hidden name=approved value=1> have this form (on the second page) submit to itself, have some code like <? if (isset($approved)) { (insert the data into your database); } ?> That way the first time they come to this page it will not send to the database, but after they submit this form it will. You will want to signal that the stuff has been submitted and maybe not show the form if $approved is set.

The saving of variables across pages is generally referred to as 'session management'. PHP4 can do this natively, but there are also several third-party libraries available for PHP3. Perhaps the most famous of these is PHPLIB:

http://phplib.netuse.de

For something like what you are proposing, however, perhaps full-bore sessions are overkill. The easiest quick-and-dirty way that I can think of at the moment is to simply iterate over the variables when creating the confirmation page and output a form with all of the variables set using <input>'s 'value' attribute. (This gets a bit tougher if you're using multiple selects/checkboxes; see the FAQ at php.net for more information on that.)

For instance, if you know beforehand what all of the form elements will be, you could do something like:

Now, the form handlers checks for the value of $action; if it's "Reject", the form is presented again; if it's "Accept", the variables are saved to the database (or whatever).

Perhaps a more elegant solution is to skip the intermediate confirmation form, and simply re-show the original form, using the value attribute to present already-entered information.

There's a tutorial on the php.net website:

http://www.php.net/tut.php3

At the end of the tutorial are links to other tutorials; in general, check out http://www.zend.com (PHP4-centric); http://www.devshed.com; and http://www.webmonkey.com.

Good luck,

Yes, this will work, but it does not allow for the calling the method within the string. I tried to keep the example simple, but there is a next step that makes this technique powerful.

Consider,

// A here doc print <<< END <HTML> Status: {$cart->show()} Count: {$cart->count} <TABLE> Contents:<p> {$cart->table("<TR>", "</TR>", "<TD>", "</TD>")} </HTML> END;

The table() method would take four arguments, a pre-string and post-string for rows and cells of the table.

The ultimate objective being to create a framework where here docs contain all of the relevant HTML code and the php class contains all of the php logic. I think a system would be nice because it would be easier to do all of the HTML formatting in one place.

I for one think that Paul's idea is a good one. A regex library of useful routines (not necessarilly just for XML) is something that can't be sneered at.

However, with PHP 4.0 beta 4 currently shipping with the expat sources included and the eventual upgrading of hosts from v3 to v4, we will probably see the necessity for regex XML processing decline in the next few months. In the meantime, I wouldn't mind seeing an example of what Paul has done.

The variable is initialized with the name of "sometext", and the value of the $sometext variable is non-existant.

Why this is handy, anyways: An _empty_ variable is data too. Things that can code off of this: isset(sometext); empty(sometext);

Generally, you'll see something more like: index.php3?sometext=1&othertext=blue

In which case the variable named $sometext has the value of "1", and $othertext variable has the the value of "blue"....

How to build these in PHP? With HREF statements, like a normal page link. To build them sutomatically in an HREF, use something like this: <A HREF="/here/index.php3sometext=<? echo $sometext ?>" >

No, I think the original answer was right. Such a case would generally add a new variable

$D2378DSLKJ26d78s = "";

What they may be doing on that site, of course, is to not use the variables defined in the URL, but to parse the URL.

A poor way to do this would be something like:

$variable = split("\?",$PHP_SELF)

$variable[1] is then D2378DSLKJ26d78s

Or they may be doing in this way:

$variable = $argv[0];

from: http://www.php.net/manual/language.variables.predefined.php

argv

Array of arguments passed to the script. When the script is run on the command line, this gives C-style access to the command line parameters. When called via the GET method, this will contain the query string.

Hey everyone,

Just a quick question for anyone who cold help me please....

I'm making a website with php where I have a kind of an article section on one page. This is replicated on another page, and I was wondering if anyone knew any code whereby i could pull text from other pages by defining what tags to pull it between. For e.g. :

<article> Article headline Date posted

This is an article headline para which acts as an introduction. </article>

I'm not using xml here, so I guess those tags would be replaced by html comments.

Could anyone help me on this ?

Thanks

Sunny

I'm sure there is a way, but it seems like it would be a lot easier if you simply moved the article to its own file, and include()'d it in all the files that want it.

I think this should work. it should strip away everything before the <article> tag and everything after the </article> tag and it'll strip the article tags as well. The only thing left will be the stuff between the tags.
