Multisite and Default Settings?

I’m planning to install this on a multisite network. However, by default all thumbnail sizes are set to display.

Is there a way of hiding certain image sizes by default?

I’m assuming something could be done to automatically inject a site option with an array of the image sizes to show? Looking in the database I can see I get the following:

a:2:{s:16:"pte_hidden_sizes";a:7:{i:0;s:16:"tiny-thumb-image";i:1;s:11:"small-thumb";i:2;s:15:"full-page-image";i:3;s:14:"featured-image";i:4;s:10:"team-image";i:5;s:12:"driver-image";i:6;s:18:"driver-small-image";}s:12:"cache_buster";b:0;}

I’ve managed to get the following together, but it’s not quite working…
```
add_action('admin_init', 'confweb_set_pte_defaults' );

function confweb_set_pte_defaults(){

	if ( !is_plugin_active( 'post-thumbnail-editor/post-thumbnail-editor.php' ) ) return;

	$pte_hidden_sizes = get_option('pte-site-options');

	if(!empty($pte_hidden_sizes)) return;

	$pte_hidden_sizes = array();

	$image_sizes = get_intermediate_image_sizes();
	foreach ($image_sizes as $size_name => $size_attrs):
		$pte_hidden_sizes['pte_hidden_sizes'][] = $size_attrs;
	endforeach;

	$pte_hidden_sizes['cache_buster'] = '';

	update_option( 'pte-site-options', serialize($pte_hidden_sizes) );
}
```
At the moment I’m just trying to get all the sizes marked as hidden, then I can adjust as required to show the ones I’m after. However at this stage it’s not doing the job.

Any ideas?

It looks like you’re overwriting other settings other than just the hidden sizes. That could be causing a problem…

I would do something like this:

$my_hidden_sizes = array( 'size1', 'size2' );
$my_default_options = array( 'pte_hidden_sizes' => $my_hidden_sizes );
$options = array_merge( get_option('pte_site_options'), $my_default_options );

Of course, the problem could be in the serialization. I handle the serialization through the wordpress backend, and don’t ever get that low level with it, so that might be where the problem is.

Ok, thanks sewpafly, The serialisation seemed to be the issue, looks like the update_option and get_option handle seriealisation anyway.

For anyone else to use / scrutinise, final code I’ve used looks like…

/* *
   * This sets the default options for the thumbnail editor plugin. We're not planning on making the settings menu available to clients.
   * So we need to set the default values to hide the most obscure of image sizes.
   *
   * */

add_action('admin_init', 'confweb_set_pte_defaults' );

function confweb_set_pte_defaults(){

	if ( !is_plugin_active( 'post-thumbnail-editor/post-thumbnail-editor.php' ) ) return;

	$pte_hidden_sizes = get_option('pte-site-options');

	// Look to see if this option actually needs to be set. Either because it's not been set before, or if it's been 2 days since we last checked.
	$transient_check = get_transient('editable_thumbnails_expires');
	if(empty($pte_hidden_sizes) || empty($transient_check)){

		$pte_hidden_sizes = array();

		// Dig out all currently registered sizes and automatically add them to be hidden
		$image_sizes = get_intermediate_image_sizes();
		foreach ($image_sizes as $size_name => $size_attrs):
			$pte_hidden_sizes['pte_hidden_sizes'][] = $size_attrs;
		endforeach;

		$pte_hidden_sizes['cache_buster'] = '';

		// Add a filter so that plugins can add image sizes to this list
		$allowed_sizes = array();
		$allowed_sizes = apply_filters( 'allow_image_size_from_post_thumbnail_editor', $allowed_sizes);

		if(!empty($allowed_sizes)){
			foreach($allowed_sizes as $size){

				if(($key = array_search($size, $pte_hidden_sizes['pte_hidden_sizes'])) !== false) {
	    			unset($pte_hidden_sizes['pte_hidden_sizes'][$key]);
				}

			}
		}

		update_option( 'pte-site-options', $pte_hidden_sizes );

		set_transient( 'editable_thumbnails_expires', time(), HOUR_IN_SECONDS * 48 );
	}

	return;
}

So that makes all image sizes hidden by default and refreshes the list every 48 hours. Then in our separate plugin it filters out the sizes I’d actually like to make editable.
