Add resource-specific mediasource and multifile-uploader to the gallery

Create the dynamic resource-specific media source

• Go to: Media->Media Sources
• Create new media source
  • name: ResourceMediaPath
  • source type: Filesystem
• Update this media source
  • basepath and baseurl: [[migxResourceMediaPath? &pathTpl=assets/mygallery/{id}/&createFolder=1]]

You may also need to create a directory with write-permissions for php: assets/mygallery/

Assign the media source to the image-field

1. Go to: Extras->MIGX
2. Edit your Config (right-click the config-item in the grid)
3. Go to the Tab 'Formtabs' -> Edit the Formtab 'Image' -> Edit the field 'Image' 3.1. At the Tab 'Mediasources' add two new Items for the contexts 'web' and 'mgr' with the newly created mediasource-id

Modify your tpl

Create a snippet with name 'addmediasourcepath' with this code:

$output = str_replace('./','',$input);
if ($mediasource = $modx->getObject('sources.modMediaSource',$options)){
    $output = $mediasource->prepareOutputUrl($output);
}
return '/' . $output;

In your tpl change the image-placeholder to something like that:

[[+image:addmediasourcepath=`3`]]

In case, you are using pthumb for image-resizing, to something like that:

[[+image:addmediasourcepath=`3`:pthumb=`w=500`]]

Change the mediasource - id, in the example above '3' to yours!

Add Upload-Button

1. Go to: Extras->MIGX
2. Edit your Config (right-click the config-item in the grid)
3. At 'Mediasource ID' put the id of your mediasource
4. At Tab 'Actionbuttons' select 'uploadfiles_db' and remove the selection 'addItem'
5. Save everything
