Passing along PHP variables

[calrockx]

I'm a little stumped here.

 

I have a DIV background set to this:

 

background: url('http://vitanova.charlesrubinoff.com/_other/includes/big_pic_image.php') center center;}

 

And the code in that big_pic_image.php reads:

<?php

if (!$_GET[image]) {
	$image = "http://vitanova.charlesrubinoff.com/sections/_other/image.php/?width=600&height=450&image=/sections/$_GET[section]/_cover/cover.jpg"; }
else {
	$image = "http://vitanova.charlesrubinoff.com/sections/'.$_GET[section].'/'.$_GET[category].'/'.$_GET[image].'"; }

header("Content-type:image/jpeg");
readfile("$image");

?>

 

 

That php file uses some variables to know which image to display.  So, for example, if I go to http://vitanova.charlesrubinoff.com/_other/includes/big_pic_image.php?section=residential in a browers, an image shows up.  If I leave off that query at the end, nothing.

 

The problem is...if I set that php file along as the DIV background, it doesn't have any queries attached to it, so no image comes up.  Is there a way I can set it as the background, and then the big_pic_image.php looks at the browser url to know which values to give the variables?

 

How can I have this script "know" what the user clicked so it will show the appropriate image?

use basename($_SERVER['PHP_SELF'])

[calrockx]

okay, how do I implement that?

 

I tried this, but that didn't do it...

 

<?php

basename($_SERVER['PHP_SELF']);

if (!$_GET[image]) {
	$image = "http://vitanova.charlesrubinoff.com/sections/_other/image.php/?width=600&height=450&image=/sections/$_GET[section]/_cover/cover.jpg"; }
else {
	$image = "http://vitanova.charlesrubinoff.com/sections/'.$_GET[section].'/'.$_GET[category].'/'.$_GET[image].'"; }

header("Content-type:image/jpeg");
readfile("$image");

?>

 

just not sure how/where to put that

 

[sKunKbad]

Try putting this on the page:

 

<?php
echo basename($_SERVER['PHP_SELF']);
?>

 

and check the output, then you will know how to insert the code where you need it.

[calrockx]

skunkbad,

 

that echo output the file name, big_pic_image.php

 

and I found that if I add this

$query = $_SERVER[QUERY_STRING];

 

it will return the query string.  but that's if i type it in right there, it'll output that particular query. 

 

what i need is to have the div background set to http://vitanova.charlesrubinoff.com/_other/includes/big_pic_image.php  and then have that php page "see" whatever page the user is on in order to pick up the query from the url and display the correct image accordingly

Where is the style located? Inline, external, internal?

[calrockx]

oops, i should have said that.

 

it's an external css file.  i know this can be done inline, and external complicates it, but i know there's gotta be a way.

 

that big_pic_image.php, when referenced by the external css, just needs to talk to the browser and see what link the user clicked i guess, so the if-else statement will know what the query string is

[calrockx]

hm, i tried putting the php in the css and parsing it as css.  nope, no go.  the script isn't seeing the url query

[sKunKbad]

if you want to parse the css file as php, then you need to make it a php file, and make sure you use the appropriate header Content-Type = text/css.

And you're not going to be able to see what page a user is on (easily and consistently, at least).

And you're not going to be able to see what page a user is on (easily and consistently, at least).

 

$_SERVER['PHP_SELF']

$_SERVER['REQUEST_URI']

$_SERVER['SCRIPT_NAME']

 

$_SERVER['SCRIPT_FILENAME']

Yeah, that's great, now figure out what page they're on from an external PHP file that the browser fetches for CSS.
