Actions & Filters

When using filter and actions, use a filter priority above 10. We apply most of our filters around 15 or 16. To apply filters before our plugin, use a filter below 15. To apply filters after ours, use a filter above 15.

Here are some of the filters available in the plugin. See the free colorbox addon for an example on creating an addon for the plugin.

This may not be a complete list. Please search through the code for apply_filters and do_action for more filters and actions.

Examples

add_action_once ( featured_image_pro_masonry_register_scripts’, ‘myaction', 16 );

function myaction()
{
     dosomething();
}

add_filter_once ('proto_grid_container_class', ‘myfunction’, 16, 2);

function myfunction($class, $options)
{
     $class = $class . $options[‘somesetting’];
}

Actions

Initialize before the grid is created

do_action(‘proto_image_pro_init’, 
    $options //array of widget options
);

Execute an action after the query

do_action(‘proto_masonry_after_query’, 
    $query, //query results
    $attributes //the query attributes
);

Filters

Add a class to the grid container element

apply_filters('proto_grid_container_class', 
    $gridclass, //current grid class
    $options //array of widget options
);

returns modified grid class

Extract options from the arguments sent to the widget

Use this to filter out your own options from the shortcode for later use.

Move options from the $args array to the $options array and return the $options array.

apply_filters('proto_masonry_options',  
    $options,  //current array of options
    $args //arguments sent to the widget
);

Insert additional styles into the inline styles

apply_filters('proto_inline_css’, 
    $styles, //current inline styles 
    $options //array of widget options
);

Append additional scripts to the footer script.

You must encapsulate your scripts with script tags (note, this has changed since version 2 of the plugin)

$script = "
//some data
";

apply_filters('proto_masonry_footer_scripts', 
    $script, //current footer scripts
    $options //array of widget options

Add a style to the inline styles for the figcaption element

    $captionstyle, //current inline styles for the figcaption element
    $options //array of widget options
);

    $postid //the post ID
