Using header function from links

jc94062

I have a 4 pictures and previously had each picture having a <a href></a> type link to it, is it possible to be able to use the header function when one is clicked instead?

ie if ($submit) {header("http://www.site.com/page.php"); }

is how I'd do it for a submit button, what about an image though?

Thanks for any help

If one clicks on foo.gif, it'll call foo.php with $id = bread. Now something like :

if ( $HTTP_GET_VARS['id'] == 'bread' ) {

echo 'you like bread eh?';
include 'bread_stuff.inc';

}

Or stick anything in there, like a call to header() or whatever. I think this is what you mean.

Just sends me to www.site.com/foo.php?id=bread

Which doesn't exist :-) Thanks for any more help!

put that if statement into foo.php (or whatever you decide) and it will do the "stuff" within the if statement. id is an available variable within foo.php so use it accordingly, its value is 'bread' so if $id is equal to bread then "do stuff." $HTTP_GET_VARS['id'] is another way to get this value as servers can be setup where $id would not print id but using the predefined variable HTTP_GET_VARS is required. register_globals is the setting in question. this is offtopic but just one of many useful things to know. here's an example use that looks to answer your question :

if ($id == 'bread') {

header ("Location: http://www.bread.com");
exit;

}

It works and all, I can load up the page but I wanted to use the header so that the new page loads without renaming the URL, for example if I do

<?php
header("Location: http://www.site.com/page.php"); exit;
?>

as foo.php, and open it, I get the page.php opened, but the URL reads www.site.com/foo.php, if I use the method you outlined, I get the same as

<a href="page.php">pic stuff</a> and the url reads www.site.com/page.php.

Is there a way around this?

Thanks

sorry, either way above calls www.site.com/page.php

Same question though, is there any way to avoid this? (Without frame use!)

I don't know what you're talking about, what are you wanting to do? How about a simple :

<a href="<?php echo $PHP_SELF; ?>?id=bread"><img src="bread.gif"></a>

<a href="<?php echo $PHP_SELF; ?>?id=apple"><img src="apple.gif"></a>

And within the page :

if ($id == 'bread') {

include 'bread.inc';

} elseif ($id == 'apple') {

include 'apple.inc';

} else {

include 'default.inc';

}

Thats it, its working fine now.

What I really wanted to do was to open a replace the whole view of the page, so using include does it, but I wanted the URL to be www.site.com, whereas now its www.site.com/index.php?id=bread, but thats not too bad so thanks for having the patience (and skills!) to help me sort it all out.
