I'm not sure what that snippet does.. and is it right that when no radio button is selected it shows content?

I'm really forced to guess stuff here and that never brings good results :/

ok, will try start again.

From the responses i used the link
http://wiki.modxcms.com/index.php/Create_TV-Based_Chunks

and have created the snippet etc to enable a user to check a radio button which then pulls in the code from a chunk to enable reusable content.

Now i'm trying to expand that by allowing a manual override.

So.
If user selects the radio button -> show the contents on the chunk
If user doesn't select a radio button -> show the content of a different chunk.

So

[[*rightNavBoxCheck1:empty=`[[$rightnav1]]`:notempty=`[[!chunkListParser]]`]]

When i don't select a radio button is pulling in the correct chunk - i.e [[$rightnav1]]
But if a user is selecting the radio button, nothing is displaying as per it was if i just placed

[[!chunkListParser?chunks=`[[*rightNavBoxCheck1]]`]]

which is showing correctly

If i swap out the function for a different chunk just pulling it in, it displays.

Hope that explains a bit more

It might be worth trying:

[[*rightNavBoxCheck1:empty=`[[$rightnav1]]`:notempty=`[[!chunkListParser?chunks=`[[*rightNavBoxCheck1]]`]]`]]

Your just calling [[!chunkListParser]] but your not passing anything TO the parser

Alterantively try

 [[*rightNavBoxCheck1:empty=`[[$rightnav1]]`:notempty=`[[$CHUNK]]`]]

where $CHUNK has

[[!chunkListParser?chunks=`[[*rightNavBoxCheck1]]`]]

in it - but i cant recall is chunks process snippets or not. [ed. note: Tyreal2012 last edited this post 15 years ago.]

So close, it's now calling the correct radio button, but when i don't select anything it's no longer showing.

I've now swapped the logic round as per below

[[*rightNavBoxCheck1:notempty=`[[!chunkListParser?chunks=`[[*rightNavBoxCheck1]]`]]`:empty=`[[$rightnav1]]`]]

And at the moment it seems to be working. So i will continue to play around with it and do some more testing.

Thanks again everyone. Just confirmed to me why i choose MODX as a CMS to learn.

ah, you're trying to replicate the ChunkIf snippet? Attached. Might help. It is Evo but you can reproduce it.


<?php

	/*
		Name: ChunkIf
		Author: Duncan Lock <[email protected]>
		Version: 0.2
		Date: 21/07/2008
		Description:
			<strong>0.2</strong> Outputs the contents of the chunk passed in
			$trueChunk if the template variable passed in $tv is set (i.e. has a value).
			Otherwise outputs the contents of the $falseChunk chunk. Expects $tv to be the
			name of the Template Variable to test, and $trueChunk & $falseChunk to be names
			of chunks.
	
		eg:
		
		[[ChunkIf? &tv=`tvname` &trueChunk=`chunkname` &falseChunk=`chunkname` ]]
			- Long version outputs $trueChunk if $tv has a value, otherwise 
			outputs $falseChunk.
		[[ChunkIf? &tv=`tvname` &trueChunk=`chunkname` ]]
			- This short version outputs an empty string if $tv has no value.
		[[ChunkIf? &tv=`tvname` ]]
			- This very short version attempts to output the contents of a chunk
			 with the same name as $tv
		[[ChunkIf? &tv=`tvname` &debug=`1` ]]
			- Switches on debugging output - output's HTML comments for debugging.
	*/

	// get tv name
	$tv = isset( $tv ) ? $tv : '';

	// get current page ID
	$id = isset( $id )? $id: $modx -> documentObject['id'];

	// Get the value of $tv
	$tvarray = $modx -> getTemplateVarOutput( $tv, $id );
	$value = ''.trim($tvarray[$tv]);

	if ($debug) {
		$dtmp = '<!--';
		$dtmp .= 'tv: '.$tv.', ';
		$dtmp .=  'id: '.$id.', ';
		$dtmp .=  'value: '.$value;
		$dtmp .=  '-->';

		echo $dtmp;
	}

	// Decide which chunk to return.
	if ($value == '') {
		// get chunk to return if $tv has no value
		$falseChunk = isset( $falseChunk )? $modx -> getChunk( $falseChunk ): '';
		return $falseChunk;
	} else {
		// get chunk to return if $tv has a value
		if (isset( $trueChunk ))
		{
			$trueChunk = $modx -> getChunk( $trueChunk );
		} else {
			// Attempt to get the chunk with the same name as $tv
			$trueChunk = $modx -> getChunk( $tv );
		}
		
		return $trueChunk;
	}
?>
