PHP won't be able to tell you if JavaScript is enabled or not. PHP can
only determine what version of JavaScript is supported based on the browser
information provided in HTTP_USER_AGENT.

If I have magic quotes turned on for post/get/etc. in my php.ini, is there any way to temporarily turn it off for one page? For example, I have a preview page inbetween my data entry page and the page that actually saves to db. I don't want magic quotes turned on when going from the data entry to the preview page since all quotes keep getting backslashed. Is there a way to do this?

And you might also want to look at strtr() <http://php.net/manual/en/function.strtr.php>. You could, I suppose, use it to substitute some character that you know would never legitimately appear in $sometext, then do a straight str_replace() on the string for all occurences of that character.

<?php $sometext = "ThÀe cØar röøan over mÖy dog"; $thread = ereg_replace("[^[:alnum:][:space:]]", "", $sometext); echo $thread ?>

will print what you asked - of course you may not want numbers but you get the idea. I do this check on all my user inputs to php scripts- I choose what is allowed not what to deny which makes it easier.

attached mail follows:

use eregi_replace("[asutk]+", '', $string)

in this way there will be no such letters as a,s,u,t,k in $string

Hi PHPers,

the following function is supposed to build an html table, creating a content row for every row in a database table. It is creating a table with the correct number of rows, but NO content is being echoed...

I think I must be using the extract() function inside the for loop wrong... any pointers?

tia! jaxon

<?php

function news_box($max) {

include_once("inc/config.inc"); include_once("inc/db_connect_params.inc");

$link_id = mysql_connect($host, $usr, $pass); mysql_select_db($database, $link_id); //select database catalog

echo "<table border=\"0\" cellpadding=\"0\" cellspacing=\"2\" width=\"165\">";

if (!isset($max)) $max=5; //upper limit of news boxes to build

for ($i = 1; $i <= $max; $i++)

{ $sql="select i.nID, i.date, i.headline, i.subtitle, i.blurb from news_items i, news_box b where i.nID = b.nID and b.dID = $i"; $result = mysql_query($sql, $link_id); $row = mysql_fetch_row($result); extract($row); //the variables below match field names in this row

The elements in $row will have indexes like $row['i.headline'], rather than $row['headline'], just as the columns would have those names if you ran the query at the command line.

(BTW, I find that doing a var_dump() or print_r() on variables--such as $row, in this case--to be very helpful when data isn't coming out in the way I expected it to...)

I had this same exact problem just today. It all stems from the variable namespace, I think....

A similar code 'snippet' is shown below. I just made it up, but I think it illustrates my point.

<?php session_start (); function crud ($user, $password) { session_register ('user'); session_register ('password'); $GLOBALS['user'] = $user; global $password; /* NOTE: $GLOBALS['varname'] = $value is the same as global $varname. Either will work....*/ } echo "User is $user and password is $password"; ?>

Good luck with whatever you are doing,

attached mail follows:

you have to have the variable you register (in both ways) global.

so no matter how you call the function the variable must be defined global.

<? session_Start();

$foo = "bar"; session_register("foo");

function bob($user){

Global $user, $username, $username2; # In this way they can "escape the prison of function"

$username = $user . "one"; $username2 = $user . "two"; session_register("username"); session_register("username2"); return true; }

The variable I register before the function becomes available in the session to other pages...the variable I register inside the function are not accessible in the session to ohter pages. Is this normal? How can I work around this? Thanks! PHP4.0.4pl1 on Linux.

Yes it can :

here's what I once was doing to assign a user with a cookie containing a Session ID:

$uniqid = md5 (uniqid (rand()));

if(!isset($sid)) { $time = time(); setcookie ("sid", $uniqid, $time*3); }

time()+time() makes it really, really LONG ... (62 years?), of course it has not expired from anyone yet :-))

man, this is like the thread that will not die. isset() will return true for an empty string, which is not what he wants. the right thing to do is use

if((isset($var))&&($var!=""))

the isset on the left gets evaluated first so a warning is never thrown. to be even safer, you can go:

if((isset($var))&&(trim($var)!=""))

you do not want to use strlen() for the following reasons: 1) makes code unreadable -> very sloppy 2) overhead 3) it will give a warning when $var is not set (error_reporting 15 only).

Yeah and your if(isset($var) && $var != '') is pretty

You call one function and do two comparisons - vs an age old C function .... I'd like to run some numbers on that.

I run on the default error_reporting setting and it's never complained so far.

Sounds like the 'while' loop is failing because mysql_query isn't returning to $result what you think it is. Add some error-checking, starting with at least an "or die(mysql_error())" on the query. Also, try running the same query at the command line to confirm that it's valid.

Try changing this to something like $result = mysql_query("SELECT ...") or die(mysql_error()); and seeing what error is being returned by MySQL.

What is the best way to pull data from one table and insert into another? How can I delete entries from a table with a php document?

The gist of what I'm trying to accomplish is this. This is somewhat of a detailed outline, so please bear with me.

1. I have one table (members) that has all the old data. 2. I'm am going to send an e-mail to every entry in that table that has an e-mail address and have a link for them to follow to a PHP page. Any entry that does not have an e-mail address, will be moved over with a different (but similar) PHP script that will do a mass search and move of that data to the new table (memberdetail) 3. That PHP page will ask for there name and e-mail address then display a list of matching results to edit. 4. The edit page will pull data from (members) and insert then updated info into a new table (memberdetail). Password protected. Unless you know the password for that information, it will error and stop (exit () ). 5. If the insertion is successful, I want it to open a new window (if statement that contains target="_blank") which will display the new data and then the old page will refresh itself to a new page (if statement with a meta tag). If not, I want it to error and stop. (exit() ). I have already implemented anti-duplication into our new insert script (for memberdetail). The new table (memberdetail) gets scanned for duplicate information in 5 fields (but can easily but expanded to cover more then that) before it inserts data. If it finds duplicate information it displays it with an option to accept it. (password protected). If accepted (with proper password) it will delete the old information (from members) and refresh the page while opening the new information in a new window. 6. The refreshed page will be passed an variable (id) from the old table (members) and delete the entry (from members). 7. Lastly, it will refresh and pass the name and e-mail address from step 3 and display any remaining matches if any. 8. If there were any results from the search in step 7, then it will do step 4 again. If no remaining entries it will error and stop. (exit () )

Doing it this way will help us clean up our old information and get more current information for our new website. Anything that is not moved over will be erased after a couple of months. That should give them plenty of time to update and move the old data to the new site.

Thanks.

Hi,

I've submitted many times a GET form like this:

header("Location: http://examplesite.com/myscript.php3?key=value&key2=value2&keyn=valuen");

but now I need to submit a POST form.

How is this done?

I found this Perl code on the web: -------------------------------------------------------------- use strict; use LWP::UserAgent; # libwww-perl

my $ua = new LWP::UserAgent or die "new UA: $!"; $ua->agent("testclient/1.0");

my $url = 'http://localhost/cgi-bin/test.pl'; my $request = new HTTP::Request('POST', $url) or die "new HTTP::Request POST '$url': $!"; $request->content_type('application/x-www-form-urlencoded');

$request->content('field1=value1&field2=value2&field3=value3');

#$request->content('field1=value1'); # optional method #$request->add_content('&field2=value2'); #$request->add_content('&field3=value3');

my $response = $ua->request($request); print $response->content; --------------------------------------------------------------

But I want to know if there is a way of doing it in PHP...

Thanks in advance for your help! :-)

There may be other/easier solutions, but what always works for me is compiling Apache from source after removing the rpm, then compiling PHP from source. The instructions at the end of the README.config file in the Apache source distro work like a charm. This seems long-winded but at least I know it's gonna work at the end.

use flush()

it will push the output out of apache. But note, if you have a table, on Netscape not much will be shown (even if it receives the data) until the </table> arrives.

Here's what to do:

in Apache: Add (this is all one line) LoadModule php4_module C:/Webserver/php/sapi/php4apache.dll

then (five lines) AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps AddType application/x-httpd-php .php3 AddType application/x-httpd-php .php4 AddType application/x-httpd-php .phtml to your httpd.conf.

Remove(comment) Action application ... line

Copy php.ini to C:\Winnt\System32.

Copy msvcrt.dll (from C:\Webserver\PHP\dlls\msvcrt.dll) to C:\Winnt\system32 - you're almost guranteed to have it, as I did, but just check.

Copy phpts.dll to C:\Winnt\system32.

Startup the Apache service.

At this point, if it worked, you are runniong as a module.

Hopefully this will work :-)

And if it doesn't download a new version of PHP and reinstall it as INSTALL file says.

Is there a way to use PHP to tell whether a user's browser has a particular plugin?

I thought that the $HTTP_ACCEPT variable might have this type of information, but in a little test that I have done, it just returns "*/*".

I know that this can be done using Javascript, but as this can be turned off by the user etc, it seemed as though it would be more reliable to do it server side (if it is possible).

attached mail follows:

Sir, I don't see anything wrong with the syntax in your query. If I haven't over looked something, and if you haven't misspelled anything, then you have a data problem. Since your first query returns a Cartesian product, you should get something if the WHERE clause returns >= 1 row for each table. So either there are no rows in q that meet the conditions q.active = '1' AND q.global = '1' or there are no rows in c that meet the condition c.active = '1' Run the first query with only the first WHERE condition. If you get rows, add the second condition. If that works, add the third. The point at which the query stops returning rows is the point at which a subset of your WHERE conditions aren't met by the any of the rows in one of the tables.

BTW, why are you putting quotes around numbers? I'm assuming that's not the problem, since you say you did it in the query that worked, but I don't see the point.
