Get basepath from Media source by id?

Development
1

IS there a way to get the basepath form a media source in a snippet?
I’m using Image+ and need to get the image URL including the path of the media source it uses.
I only know the media source ID so what is the quickest way to get the PATH form a media source?

the snippet addmediasourcepath from here could do that
https://docs.modx.com/extras/revo/migxdb/migxdb.tutorials/migxdb.create-a-basic-gallery-management-from-scratch-with-migxdb/add-resource-specific-mediasource-and-multifile-uploader-to-the-gallery

This might work (assuming that it’s a file media source object):

$ms = $modx->getObject('modFileMediaSource', $mediaSourceId);
$bases = $ms->getBases();

$absolutePath = $bases['pathAbsolute'];
$relativePath  = $bases['pathRelative'];

It might be more correct to call getObject() with the parent class if it works:

$ms = $modx->getObject('modMediaSource', $mediaSourceId);

Tnx Bobray,

that works

Here’s a half finished snippet to get media source attributes that might be useful.

Needs work but might provide a fast start for someone.

<?php
/**
 * getMediaSourceAttribute
 *
 * DESCRIPTION
 *
 * Gets specified attribute of specified media source id
 *
 * PROPERTIES:
 *
 * &msId: string, optional, id of media source to get attribute from, defaults to default media source
 * &attribute: string, required, attribute to get value for from media source.
 *          options: basePath, baseUrl, thumbnailQuality, skipFiles
 * 
 * DEPENDENCIES:
 * 
 * None
 *
 * USAGE:
 *
 * [[getMediaSourceAttribute?
 *   &attribute=`basePath`
 *   &msId=`2`
 * ]]
 *

    /**

I’ve had to dig into media sources again for something I’m writing. I want to generate a link to edit a particular file in the Manager. The link is easy enough to write, but it requires the ID of the media source. It’s easy to get the media source’s basePath (relative or absolute) using the method I wrote about above.

Unfortunately, I haven’t found an easy way to start with the full path of the file and then get the ID of the media source containing the file. If anyone knows a way, I’d love to hear about it.
