I have something that is worked out later on in the page, say 3/4 of the way down...but a script I have (that needs to go in the <head>) needs to know the thing that is worked out in order to function...

Is there any way with php to change the <head> after something has been queried and worked out... and in case you ask, it's not possible for this query to go before the javascript at all.

Aureole · October 9, 2007

I have found a way around this (believe it or not)... so nevermind.

But I'd still like to know, is something like this possible and if so how difficult is it?

What, a guy in a dress?

Sorry.. couldn't resist...

Well, hackish solution is to use output buffering, and if you later in the page needs to insert something into the page, just modify what's in the buffer. However, the good solution is to structure your web pages in such manner, that all the output comes after the code logic, so that when you start outputting, you already know everything there is to output.

But I'd still like to know, is something like this possible and if so how difficult is it?

I generally try pushing all output to the end of my script. I do all my calculations first before anything goes to the screen.

Here's the basic structure.

<?php

// filter POST and GET data, if any

// run queries based on filtered data

// process all necessary information for output

?>
<html>
<head>
<title>
<?=$page_title?>
</title>
</head>

<body>

<!-- lots of html -->
<?php
// some php
?>


</body>
</html>

I'll try get into that habit but it can't always be done that way...for my forum I need to do a while() loop to show all the topics in a forum (for example), there's not really any way to do this before echoing any html (I don't think).

MmmVomit · October 9, 2007

Are you doing something like this?

<?php

// lots of code omitted
// query to grab a page worth of posts
$result = mysql_query($sql);

?>

<html>

<?php
// display posts
while($row = mysql_fetch_assoc($result))
{
  // do error checking here
  // display post
}
?>

</html>

Aureole · October 9, 2007

Kind of but it's a lot more complicated than that and I'm not doing any error checking on pages that display posts 'cause there's nothing to check for.

MmmVomit · October 9, 2007

What are you doing? I'm genuinely curious.

Aureole · October 10, 2007

Shall I paste the code for my Forum Index?

MmmVomit · October 10, 2007

Please do.

All the empty menu stuff at the bottom is just there as I was testing some IE bug out where if the page doesn't have enough content to scroll then it juts to the left..so I added a crap load of content... until I work it out.

Now that you have it working, you might want to go and clean it up a bit. Break pieces down into functions or something because intermingling PHP & HTML that much becomes difficult to read very fast. Throw in some CSS and Javascript and you have a perfectly unmaintainable site.

MmmVomit · October 10, 2007

Not to mention some comments.

Aureole · October 10, 2007

Eh when I wrote it my prime concern was getting it to work properly... now it does I'll try clean it up...
