Hi everyone,
I'mt trying to do the below query which itself works correctly, but when I
add a order by statement just bombs.

$query = "select * from articles where ( {$now} BETWEEN startdate

$query = "select * from articles order by startdate asc where (
{$now} BETWEEN startdate AND enddate) and categoryid = 1 limit 0,3";

This one just doesn't work, can you tell me what I have done wrong??

Thanks

Err.. ORDER BY comes at the END of your query, not the start.

SELECT * FROM blah WHERE blahblah ORDER BY y ASC LIMIT x,y

Java is just a specialized DOM... in my opinion.

Where did you get this weird idea... JAVA by itself has nothing to do
with the web or documents... It's commonly used to perform such tasks,
but it's not the "purpose" of the language. You could as well say that
PHP is just a specialized email-form language, which would also be not
quite right.

You're confusing two different things.

The DOM is a standard API developed by the W3C for addressing tree data
structures, generally XML or a data structure that maps to XML. It is
language-independent, which is why the Javascript DOM functions look and act
really really closely to the PHP DOM functions. Do not expect the DOM API to
change any time soon.

XHTML is a particular XML DocType. One can manipulate it using the DOM API.
That is very frequently done using Javascript, but in PHP 5 can be done in
PHP as well with essentially the same API. The DOM functions can be a bit
clunky, though, so various Javascript libraries exist that wrap them up into
some easier syntax. My preference is for jQuery, but there are many others.

Web 2.0 is a marketing term for a technical style and visual design movement.
It was invented by Tim O'Reilly as a somewhat joke, and picked up by people
with too much time and not enough brains to mean "Dot Boom 2.0".

Web 3.0 is a fictional term that is used only to make fun of people who use
the term Web 2.0 with a straight face.

What you're actually asking for is new elements in the DocType that offer
richer form elements. Do not expect that any time soon on a massive scale.
HTML/XHTML is unlikely to get such a thing any time soon. There is the
XForms standard from W3C, but I don't know of anything that actually uses it.
Microsoft would say "just use .NET", but that just gets boiled down to some
variant of Javascript that runs only in every bug-fix release of IE.

Probably the only useful "richer forms" system right now with any mass-market
adoption is XUL, which is the XML-based interface language used by Gecko, the
Firefox engine. It runs in pretty much any version of Firefox, but is a very
different animal from HTML.

Hi,

I'm calling a MySQL Stored Procedure via PDO (PHP 5.2.3)

$stmt = $dbh->prepare('CALL forum_post(?, ?, ?, ?, ?, status, thread_id, message_id)');

At the moment in order to get the values of status, thread_id and
message_id I need to issue a second query:

$sql = "SELECT status AS status, thread_id AS thread_id, message_id AS message_id";

and then foreach my way through it:

foreach ($dbh->query($sql) as $row)
{
        $status = $row['status'];
        $thread_id = $row['thread_id'];
        $message_id = $row['message_id'];
}

Which seems a bit insane.. is there no way to do a bindValue at the
same time as I do my bindParams?

Now I write this I really can't remember why I am even putting that
second query into a foreach loop, even so it's still a step I'd like
to remove entirely if possible?

Cheers,

Rich

It's not an INOUT parameter though.

1. Make your links point to <img src='show.php?FileName=111.jpg' />
2. In show.php, try the following:

<?php
        // This assumes all your images will be in "images/"
        // It also prevents using ../ for security
        $file = basename('images/' . $_GET['FileName']);

        if (file_exists($file)) {
                // You may need to use header() to send more headers,
                // eg. Caching headers (A very good idea) find out more

If you use $_SERVER['REQUEST_URI'] you can do all sorts of interesting things.

Say for instance you create a directory at the root of your site
called /images and put an index.php in there. Then inside of that
index.php you can parse the REQUEST_URI against some settings you'd
like and create your own sort of mod_rewrite rules out of it.

Here is an example:
<?php
var_dump($_SERVER['REQUEST_URI']);

$matches = array();
$result = preg_match('/([0-9]+).jpg$/D', $_SERVER['REQUEST_URI'], $matches);
if ($result == true) {
echo 'Requested image: '. $matches[1];
}
?>

You can translate that 1111 to your image via a database call such as
SELECT imagename FROM hiddenimages WHERE id = 1111 or whatever you
want. People can still directly link to your images using this
technique.

Given that, you might also reconsider why you are hiding your image
filenames. Are you trying to protect them from unauthorized viewing?
If that is the case you can use the real filenames, but pass them
through a script that checks for a session set to you know that only
authenticated users can see them.

Your primary script would echo:

         while ($row = mysql_fetch_array($result))
         {
                 // get the file name from the data table
                 $FileName = $row['filename'];

// encode the filename to be legal in an URL
$FileName = urlencode($FileName);

                 // download to browser
                 echo <<<_
<img src="show.php?FileName=$FileName" />
_;
         }

and the secondary script show.php could use logic such as this:

         // if the querystring contains the expected parameter
         if (isset($_GET['Filename']))
         {
                 // get requested filename
                 $Filename = 'img/' . $_GET['Filename'];

                         // if that file exists
                         if (file_exists($Filename))
                         {
                                 // output to browser, suppressing
error message
                                 readfile($Filename);
                         }
         }

Notes:

Your sample script included:
echo "<img src='http://www.mysite.com/img/{$FileName}'/>";

Marking up your images as <img ... /> indicates that you want to use
XHTML. XHTML requires that attributes be quoted with double quotes,
not single quotes (apostrophes). Use <http://validator.w3.org/> to
validate your markup.

However, simply reversing the quotes in your statement would result in:
echo '<img src="http://www.mysite.com/img/{$FileName}"/>';
This would not work because PHP would fail to expand the variable
name inside single quotes. Therefore you'd need to escape the inner
quotes like so:
echo "<img src=\"http://www.mysite.com/img/{$FileName}\"/>";
or use heredoc (<<<...) which I prefer to use because it means not
having to escape the quotes. In a case like this it also means not
having to enclose the variable in curly braces:

echo <<<_
<img src="show.php?FileName=$FileName" />
_;

urlencode: http://php.net/urlencode

heredoc syntax: http://php.net/heredoc#language.types.string.syntax.heredoc

isset: http://php.net/isset

file_exists: http://php.net/file_exists

It should be pointed out that you can't really hide the real URL of
your images. If an image appears in a browser, the browser will
accurately report its location to the user, and the user can save it
to their hard drive.

If you're in a situation in which you're trying to avoid people
downloading images without permission, your best bets might be to
watermark, crop, low-res-ify, or otherwise disfigure the displayed
images to make them less attractive than the originals.

a heredoc for a single short line? why? isn't echo '<img
src="show.php?FileName='.$FileName.'" />'; just as easy? Or is it
because you didn't feel like escaping the double quotes and/or
concatenating strings? (yes, I really dislike heredoc, I know)

http://php.net/readfile

"Reads a file and writes it to the output buffer.

"Returns the number of bytes read from the file. If an error occurs,
FALSE is returned and unless the function was called as readfile(),
an error message is printed."

I figured that in the case of an image it would make more sense to
download a FALSE value to the browser than a text error
message. During development & debugging phases error messages are
invaluable, but after publication some circumstances dictate no
display rather than display of a message. Since the OP was looking
for a solution that obfuscated the image URL, I thought the less
techy information communicated to the user the better.

Richard Heyes' suggestion of using passthru() might work better if it
can be used with a mixture of content types on the same page.

And, yes, heredoc is definitely a matter of taste. In my own work,
its disadvantage (hugging left margin) is outweighed by its
advantages (separation of logic from data/template/output, omission
of escape codes except the occasional {}, fewer typographical errors,
faster proofreading, etc.). I don't feel the need to convince anyone
else to use heredoc, but I'm totally sold on it myself.

Regards,

Paul

Hi Nathan,

There really isn't much to explain about it other than the fact that
Apache will give you the raw user input that is sent to it in
REQUEST_URI. Usually if a user is just clicking around it will be the
current page you are on.

Since we know that it will give us any user supplied value to it, we
can play around with those values by generating any sort of URL we
want.

If you create a file called blah.php and stick it in a web directory
somewhere then you might access it like this:

http://localhost/blah.php/?/hello

Here is the contents of blah.php:
<?php
var_dump($_SERVER['REQUEST_URI']);
?>

Here is the output:
string '/blah.php/?/hello' (length=17)

A few other urls:
http://localhost/blah.php/sometext
http://localhost/blah.php/?/category-23/item-164

Results:
string '/blah.php/sometext' (length=18)
string '/blah.php/?/category-23/item-164' (length=32)

If you replace blah.php with an index.php then you can have a cleaner
URL at the cost of not being able to use the $_GET superglobal. If we
were to try http://localhost/blah/somefile/111.jpg we would get a 404
error. To get around this you can add a query string in the url and
it works again. That is why you cannot use $_GET variables. If you
create a /blah directory and place an index.php in there you can do
this:

http://localhost/blah/?/somefile/111.jpg

Output:
$_SERVER['REQUEST_URI']: string '/blah/?/somefile/111.jpg' (length=24)
$_GET: array '/somefile/111_jpg' => string '' (length=0)

So there are some tradeoffs with something like this. It leads to a
cleaner url that you can easily parse with any preg_match. I only use
it in specific instances where I know that I'm only going to need
something like the 12 and 2 from /gallery/category-12/item-2.

Hey, on a side-note, has anyone else realized that this is
apparently the only PHP thread in the history of the list to not have
the prepended [PHP] in the subject line?

.... or am I going retarded again?

This has been confirmed. For whatever reason, Gmail isn't showing
me the [PHP] mark in the subject for this thread. Perhaps because I'm
the OP.

It's not the only, about 50% of threads have it, and another 50% don't.
For instance, the DOM thread does not have it, this thread has it in
between Re:'s, Hide the real URL has it, Pirate PHP books doesn't, etc.

I don't get them on any of my messages but then I read them all via nntp

What are you talking about??? That has to be an artifice of Gmail (and other clients?) -- every single message I've seen in every one of those topics has the [PHP] marker, just not always in exactly the same place:

   [PHP] About DOM function in PHP
   Re: [PHP] About DOM function in PHP
   [PHP] Re: About DOM function in PHP
   Re: [PHP] Re: About DOM function in PHP

   [PHP] Pirate PHP books online?
   Re: [PHP] Pirate PHP books online?
   [PHP] Re: Pirate PHP books online?
   Re: [PHP] Re: Pirate PHP books online?
   [PHP] Re: Re: Pirate PHP books online?
   Re: [PHP] Re: Re: Pirate PHP books online?
   Re[2]: [PHP] Re: Pirate PHP books online?
   Re: Re[2]: [PHP] Re: Pirate PHP books online?

I think I can kinda see a logic in there to do with a combination of smart and dumb email clients, and when the PHP list server adds a [PHP] marker, but I leave it as an exercise for the reader to figure out what it is... ;)

Bottom line, the [PHP] marker *is* there on every message, and if you're not seeing it it's 'cos your client is (for whatever reason) stripping it.

Cheers!

From the 18 USD, they payed me the proofreader and helped me to get
better layout.

And yes, if the book is sold over the normal bookstores I will earn
around 2 USD, but, - since I am using BOD, - I can sell the book my
own which mean, if I sell it for the same price, I earn 5-6 USD.

BUT, I have to pay the distribution and administration for it.

The way that i generally handle this is to use a class. I instantiate an
object when the page loads, whether the form has been submitted or not.
Then, if it has been, i populate the object's values with the data
that's been posted, doing whatever validating that is required. Once
that has all been taken care of, the script checks to see if the object
has any errors set. If not, it then persists the data to the database
(or whatever is required).

If there are errors, i display the form again. However, this time the
object has values filled in. Thus, i can use form elements like so:

<input id="foo" name="foo" type="text"
value="<?= $my_object->getFoo() ?>" />

Because i've instantiated the class even on the initial page load, the
getFoo() method simply returns NULL the first time. Another benefit is
that you can have default values for the class that the object will
populate the form with.

Also, you can set the error messages in the class, so the object can
display them at the proper place:

-- snip --
<?php
if ($my_object->hasError())
{
?>
<p class="Error">There was an error with the submission. See below.</p>
<?php
}
?>

...

   <label for="first_name">first name</label>
   <input type="text" id="first_name" name="first_name"
     value="<?= $my_object->getFirstName() ?>" />

<div class="Error"><?= $my_object->getError('first_name') ?></div>
</fieldset>

-- snip --

So, if the object's error array has something for the key 'first_name',
an error is returned. If not, NULL is returned.

In any case, no session is required.

I'm trying to use PHP to compose an HTML formatted email and I'm running
into some small problems.

1) When using "Content-Type: multipart/mixed" during my testing both
Thunderbird and Gmail display the plain text and html version of the
email and Firefox attaches the html portion as an attachement.

2) When using "Content-Type: multipart/alternative" during my testing
Thunderbird only showed the HTML portion of the email but Gmail
displayed only a blank email.

3) Spam Assassin doesn't like it either way and tags the email as SPAM
for the following reasons:

0.6 HTML_SHORT_LENGTH BODY: HTML is extremely short
0.0 HTML_MESSAGE BODY: HTML included in message
1.5 MIME_BASE64_TEXT RAW: Message text disguised using base64 encoding

Here is the script, which I mostly borrowed from tutorials/how to examples on the web.

$to="Tom Ray <listsblazestudios.com>";
$from="Support <testingblazestudios.com>";
$subject="Test HTML Email";

// --> plain text part of the email
$msgtext="This is HTML Testing";

//--> html part of the email
$htmlmsg=chunk_split(base64_encode("This is <b>HTML</b> testing."));

//--> create boundary
$sep = strtoupper(md5(uniqid(time())));

//--> create email
$header = "From: $from\n";
$header .= "MIME-Version: 1.0\n";
$header .= "Content-Type: multipart/mixed; boundary=$sep\n\n";

$header .= "--$sep\n";
$header .= "Content-Type: text/plain; charset=ISO-8859-1\n";
$header .= "Content-Transfer-Encoding: 8bit\n\n";
$header .= "$msgtext\n\n";

$header .= "--$sep\n";
$header .= "Content-Type: text/html; charset=ISO-8859-1\n";
$header .= "Content-Transfer-Encoding: base64\n\n";
$header.= "$htmlmsg\n\n";
$header .= "--$sep--";

//--> mail it
mail($to, $subject, "", $header);

Any help/suggestions would be appreciated.

attached mail follows:

I know it's not specificly a fix to your problem but it might be the easiest
solution. Check out http://phpmailer.sourceforge.net/ it lets you specify
an html and text body meaning it handles all the content-type stuff for you.
It's really a nice solution.

attached mail follows:

I need to test a bunch of code that extensively uses a mysql database (both
selects and inserts), and I want to do it without actually writing to the
database.. Instead of commenting out all of the $db->query($insert_query)
statements and echoing $insert_query, I thought I'd make the following
object:

class TestDB {
    var $realDB;
    function TestDB(&$o)
    {
        echo $o;
        $this->realDB = &$o;
        echo $this->realDB;
    }
    function query($q)
    {
        echo $q;
    }
    function getOne($q)
    {
        return $this->realDB->getOne($q);
    }
    function getRow($q)
    {
        return $this->realDB->getRow($q);
    }
    function &resetDB()
    {
        return $this->realDB;
    }
}

Then, in my code, I instantiate it like so:

$tmp = new TestDB($db);
$db = &$tmp;

But this doesn't work, and I can't figure out why. When I try to call
$db->getRow($q) I was getting an error that said that I couldn't call a
member function of a non-object. I've changed things around now, and I'm
just not getting anything. Any idea why I would get the non-object error?
Thanks.

attached mail follows:

Found the problem. The piece of code was outside of a block where $db had
been created, so it was a non-object the whole time... Easily fixed, but a
hard error to find when I'm assuming it's my brand new class that's the
problem.

Most likely it's the server's time/date problem. Did you check to make sure
that the time/date is in the correct timezone, etc? I know this isn't
really the right way to do it, but you could always just move the server's
clock back 10 hours if it's really always 10 hours ahead of time. You
alternatively could also always use a different way of sending your mail for
that server. If you used PHPMailer http://phpmailer.sourceforge.net/ this
allows you to connect to SMTP on a different machine to send email from an
account. This one is really tougher than I origionally thought.

The time on the machine is correct, and out of all of the date stamps in the
headers of the email are formed correctly based on the machines time/date,
(ie, everywhere else in the headers it adds the +1000 correctly) except in
the 1 main line

> Date: Day 00th Jan 2999 01:02:03 ?1000

Email programs (Wintendo based, and *nix based alike) generally have a hard
time with this Date header. Outlook and Outlook express just try and
interpret and guess what its supposed to mean (seemingly adding an extra 10
hours to the correct timestamp) and the *nix mail filter I came across
reported it as being a bad header.

While we can point you in the right direction we can't build your project
for you. You cover such a wide range of topics it's like you're trying to
write a huge project but don't know actually how to use PHP. My
recomendation is to go get a good PHP book, there's been a lot of discussion
about good books in the newsgroups in the past, and read that. Most of
these topics are covered to some extent in a good book.

Also your question is really hard to follow, take a look at this

I have a situation where there is a single image let's call it somebody.jpg.
I want to be able to dynamicly create this image using php, basicilly I have
PHP set to handle .jpg files also, so I then go through and create an image
based upon some info I get from a database call and then use
header('Content-Type: image/jpeg');
passthru($file);
to send the image to the user.

My problem is once they view the image their browser "helpfully" caches it
so they don't have to download it again.

Is there any tactic short of changing the name constantly of the image to
avoid browser caching of an image?

Solution 1:
Send a header() that avoids caching (can't remember it exactly)
Solution 2:
Call the image like this:
<img src="image.jpg?arandomstringhereeachtime">
Or if you were creating it with a php script:
<img src="image.php?img=image.jpg&arandomstringhereeachtime">

My preferred way of doing it, and making sure its reloaded each time is to
do it this way... the U variable pretty much guarantees a random string each
time its loaded.

You can try:

header('Cache-Control: no-store, no-cache, must-revalidate,
Post-Check=0, Pre-Check=0');

That's HTTP/1.1 only, but this is what I got from PHP site:
<?php
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
?>

But wouldn't that make every image on the page be uncached and reloaded each
time? Not very efficient if the shell of the site keeps getting loaded if
only 1 or 2 images need to be forced.

Yes, that depends on which way it is used, I wouldn't recommend
loading images from the database that don't get changed...
And you can of course also use an
if-statement/switch-statement/in_array function in your image.php
script, like this:

$img = $_GET['img'];
if($img == "test_a.jpg" || $img == "test_b.jpg") {
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
}

OR:

$img = $_GET['img'];
switch($img) {
case "test_a.jpg":
case "test_b.jpg":
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
}

OR:

$img = $_GET['img'];
$noncached_images = array("test_a.jpg","test_b.jpg");
if(in_array($img,$noncached_images)) {
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
}

Is this header you're refering to the header of the page which contains the
image, or the image itself?

The image itself.

Also note, that if you use my solution 2, you still might get
problems, as the page that is calling might be cached, and in the
cached page, it refers to the image with the same unique code, and it
will use the cached image again.

Also, if you use solution 2, the image will still stay forever in the
temp folder of the browser(unless the user is cleaning it). If you use
solution 1, the browser will keep it only for this page, and will
remove it afterwards.

Well, this is only one specific image that constantly changes, the rest of
the page is handled regularly.
From what you've said if I go with this
header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past

That will effect only the one specific image I use this on when generating
it right?

Here is my suggestion. You COULD use strtotime() and try and have PHP see if it recognizes the
input string as a date time stamp or something.

Live example
http://www.cmsws.com/examples/php/is_date.php

source

<pre><?php

function is_date($in) {
return (boolean) strtotime($in);
}

$dates = array(
                'tomorrow',
                'yesterday',
                'next week',
                'last year',
                'April 1st',
                'December 23, 1999 4pm',
                );

foreach ( $dates AS $row ) {
        echo "Time is: ".date('c', strtotime($row));
        echo " {$row} is ";
        var_dump(is_date($row));
}
