Using the site_url tag in a snippet

Hi,
A newbie question (currently learning by developing simple snippets), but cannot figure the anwser out !

I need to use [[++site_url]] in the snippet below to get the full url of an xml file resource to parse :

<?php
$myxmlfile='http://www.example.com/'.$myxmlfile;

$myslider = simplexml_load_file($myxmlfile);

$totals=count($myslider);

for ($i = 0 ; $i < $totals ; $i++) {
			
$modx->setPlaceholder('url_slide',$myslider->SLIDE[$i]->URLSLIDE);
$modx->setPlaceholder('pics_file',$myslider->SLIDE[$i]->PICSFILE);	
$modx->setPlaceholder('pics_alt',$myslider->SLIDE[$i]->PICSALT);	
$modx->setPlaceholder('pics_legende',$myslider->SLIDE[$i]->PICSLEGENDE);	
$modx->setPlaceholder('pics_legende2',$myslider->SLIDE[$i]->PICSLEG2);

$output .= $modx->getChunk('slider.slide');	
			
}

return $output;

The snippet is called this way : [[!slider? &myxmlfile=`slider-home.xml`]]

When i replace http://www.example.com/ by [[++site_url]] it doesnt work !!
(i haven't added any slash)

When i use [[++site_url]] in a basic snippet e.g. including :

$output ='[[++site_url]]'; return $output;

it worls perfectly and prints (as it should) : http://www.example.com/

What's wrong ??
Thanks !

You can't necessarily reference the '[[++site_url]]' string in a snippet -- it's "magic" comes from the MODX parser, which parses your content and templates, but not your PHP code in a Snippet. The good news is that all those special placeholders are available as MODX system settings or as PHP constants or both.

$site_url = $modx->getOption('site_url');
// or
$site_url = MODX_BASE_URL;

For what it's worth, you might be able to get your full url using MODX's makeUrl() function: http://rtfm.modx.com/revolution/2.x/developing-in-modx/other-development-resources/class-reference/modx/modx.makeurl

If you're linking to a MODX document, you can get the full URL by verbosely setting the "schema" option:

[[~123? &schema=`full`]]

You can get the same effect by adjusting the link_tag_schema system setting to "full".
