Hi, I am trying to create a snippet that change the size of a video automatically.

My snippet is called youtube

<?php
$Input = $modx->getTemplateVarOutput('video-01');
    $Input = $Input['video-01'];

    $Input= preg_replace('/width="640"/', 'width=570', $Input);
    $Input= preg_replace('/height="505"/', 'height=338', $Input);

    $Input= preg_replace('/width="480"/', 'width=570', $Input);
    $Input= preg_replace('/height="390"/', 'height=338', $Input);
    return $Input;
?>

the html: [[youtube]]

The problem is that I have 30 template variables, named video-01,video-02,video-03 and so on, so I would like to put the TV inside the snippet call, like this [[youtube? &Input=`[*video-01*]`]].

I have already tried but it doesn’t work. it returns stuff like this

<object widt" 
><object widt 			   >

Does anyone have any idea or suggestion?

your post is old and I don’t have an answer, but a hint:

$Input= preg_replace(’/height="505"/’, ’height=338’, $Input);

on the search string there are double quotes around the number, in the replace string there aren’t.
Is that correct for what you want to happen?

Thanks Vegano, I have already solved it

This is the snippet

<?php
$Input = $modx->getTemplateVarOutput('video-'.$num);
    $Input = $Input['video-'.$num];

    $Input= preg_replace('/width="640"/', 'width=630', $Input);
    $Input= preg_replace('/height="505"/', 'height=360', $Input);

    return $Input;
?>

This the call:

[[youtube? &num=`01`]]
