Comparing MODx variables in snippets

Ok, so I can’t do this in a snippet:

<?php
$foo="[*parent*]";
$bar="[*somevariable*]";
if ($foo == $bar) {
echo "T";
}
?>

for whatever the reason. The variables foo and bar seem to be set as should, but the comparison doesn’t work. How should I do this?

--edit--

$foo can (apparently) be set like this:

$foo=$modx->documentObject[’parent’];

so now I just need something similar for template variables (i.e. for [*somevariable*])... In MODx documentation I found this:

http://modxcms.com/gettemplatevar.html

but "usage" part on that page says nothing to me ($idname?, $fields?, $docid?, $published?), so how do I get the value of the template variable to a php variable?

From looking at the code briefly,

$idname is the numerical id of the tv, can also be an array of such
$fields are the fields you want, defaults to ’*’ so it will get all of them, you can leave this I guess
$docid allows you to specify a particular document, if you don’t, current document is used
$published allows you to specify if you want only published docs, this is the default.

it will return an array or false if it fails

The return value you want is ’default_text’ I think in the returned array.

With this:

$bar = $modx->getTemplateVar("somevariable");
echo $bar[’value’];

I get the contents or ’value’. Now unfortunately the content is @INHERIT. That’s not what I want. I want it to be what it’s supposed to inherit...

You need to use getTemplateVarOutput(); to get the rendered output of the TV,

Try this:


getTemplateVarOutput returns an array.

lol, someone beats me to this, but read the wiki lots of nice API pages

you can use $modx->getTemplateVarOutput() instead

Ok, getTemplateVarOutput did the trick, thanks I’m off to the next problem then

--edit--

Actually, I’ll just ask you guys right now and save myself a lot of trouble. How do I get the output of this:

[[UltimateParent? &top=`[*somevariable*]`]]

to a php variable?

In that syntax the name of the parametr becomes a var automatically. Therefore, in your example the &top=`` parameter can be accessed via the $top variable in the snippet code automatically.

So if you would simply echo $top; it should read the contents of the TV [*somevariable*]

I got the result I wanted with this:

$bar=$modx->getTemplateVarOutput("somevariable");
$baz=$bar[’somevariable’];

$params[’top’]="$baz";
$bax=$modx->runSnippet (’UltimateParent’, $params);

Maybe not that elegant, but seems to work just fine
