I’m needing to get some variable HTML code written into a "header" chunk... hence some PHP code, hence a snippet. Never tried to do this yet, but I have to start some time!
Here is the code I put into my snippet:
<?php
print ’<style type="text/css">’;
print ’ /*<![CDATA[*/’;
print ’ #logo {width:100%;height:100px;min-width:400px;background:#FFF url("assets/templates/mytemplates/myclass/images/custom/grass-hill.jpg")}’;
print ’ /*]]>*/’;
print ’</style>’;
?>
However, what appears as a result of this (in my final HTML) is as follows:
<style type="text/css"> /*<![CDATA]>*/</style>
which is missing a bunch of my text (including part of the CDATA construction and the entire 3rd line). This code works fine if I put it into a test.php file and call it directly (bypassing modx), so I’m fairly certain that something in modx is treating it differently than I expected.
I’ve looked up the online documentation about snippets to see what I can find concerning special considerations for characters like #, *, etc., but haven’t been able to find anything other than a few very terse paragraphs about how to call snippets.
Can anyone suggest what I might be doing wrong, and if there is a section of documentation that covers this (honest I’ve looked!), and if this is even the right approach to what I’m trying to accomplish?
Thanks,

Sorry... relevant facts:
modx 1.0.5
WAMP

PHP 5.3.5

To answer your question tangentially:
If you’re wanting to output a different background image depending on conditional input, you can do this using a Template Variable (ie [[*customImage]] with the rest of the style declaration in the chunk, or you can use a snippet to set a placeholder in the chunk:
$customImage = 'assets/templates/mytemplates/myclass/images/custom/grass-hill.jpg';
// or some method of retrieving the image, eg from $_POST or a dbquery
$output = $modx->toPlaceholder('customImage',$customImage);
return;
Would mean you could put [[+customImage]] wherever you wanted on that page.
Or you could return $customImage and not set a placeholder and call the snippet in a specific place.

Yes, that’s exactly what I’m attempting... a different background image as a result of a dbquery (so that users can "customize" the web site according to their own preferences).
I haven’t yet gotten into setting Template Variables at run time the way you’re describing, so I’ll have to read up on that a bit more, but it looks like a much more efficient way of accomplishing what I’m wanting.
Thanks for pointing me in that direction!
