Passing URL variable to ditto chunk

Hey all,

There may be a super-simple solution for this, but I can’t seem to find a way. I want to pass a variable in my URL to the ditto chunk that is output on the page.

The URL is http://www.mysite.com/page.html?somevar=somevalue

And the ditto chunk is

<div><a href="[+url+]">[+pagetitle+]</a><br />[+introtext+]</div>

I would like the link in the chunk to go to

[+url+]?somevar=somevalue

but obviously I can’t put a snippet like

<?php $_REQUEST['somevar']; ?>

in the chunk, which would be the easiest solution.

Anyone got any ideas?

Thanks

Use a TV with

@EVAL return $_REQUEST['someval'];

then you can use [+tvname+] in your tpl (I think; not tested).

I tend to avoid using URL strings; to pass a value I can use a mini-form with a submit button styled to look like a link or whatever I want, or if there are several options use a fancy radio button block, and pass the value in the POST instead.

you can use a small snippet for that, just put the code in a snippet and call it in t he ditto template. (make sure you striptags etc for security)

snippet contents would be something like this:

<?php 
$output =  strip_tags($_GET['somevar']); 
if isset($_GET['somevar']){
   return "?somevar=".$output;
}else{
return;
}
?>

then the chunk would be like this:

<div><a href="[+url+][[snippet]]">[+pagetitle+]</a><br />[+introtext+]</div>

make sure that you call you ditto uncached [!ditto....!]

Great. Thanks Dimmy.

You had a minor typo, so I tweaked the code a tiny bit

<?php
$output =  strip_tags($_GET['postcode']); 
if (isset($_GET['postcode'])){
   return $output;
}else{
return;
}
?>

Works perfectly.

I knew there was an easy fix. Thanks.
