Multi Media

The Redux Multi Media extension is an improved way to allow your users to upload and/or select multiple files from the WordPress media library, for use in the Redux Framework options panel.

Getting Started

To understand how to use extensions, you should read this article on Loading Extensions. To shortcut the process, you should use the Redux Generator. Please be aware that a working knowledge of PHP and CSS is required to properly use this field. Should you not be familiar with one or the other (or both), please refer to the basic guides to get you started: Getting Started with PHP, CSS Introduction.

Example Declaration

array(
    'id'        => 'opt-multi-media',
    'type'      => 'multi_media',
    'title'     => 'Multi Media Selector',
    'subtitle'  => 'Multi file media selector',
    'labels'    => array(
        'upload_file'       => __('Select File(s)', 'redux-framework-demo'),
        'remove_image'      => __('Remove Image', 'redux-framework-demo'),
        'remove_file'       => __('Remove', 'redux-framework-demo'),
        'file'              => __('File: ', 'redux-framework-demo'),
        'download'          => __('Download', 'redux-framework-demo'),
        'title'             => __('Multi Media Selector', 'redux-framework-demo'),
        'button'            => __('Add or Upload File','redux-framework-demo')
    ),
    'library_filter'  => array('gif','jpg','png'),
    'max_file_upload' => 5
),

Example Usage

The extension’s return value is an array of key/pair values. The key contains the file’s post ID, while the value contains the URL of the file itself. It will be necessary to use a for/each loop to extract the values (Please remember to replace redux_demo with your own opt_name argument).

global $redux_demo;

foreach ($redux_demo['opt-multi-media'] as $id => &url) {
    echo 'Post ID: ' . $id;
    echo 'URL: '     . $url;
}

getExtendedData Helper Function

The Multi Media extension includes a helper function to extract a wide variety of data for any post ID passed to it. To take advantage of this function, use the following code (to obtain a post ID, use the code above in conjunction with the code below):


// the $id variable assumes a valid post ID.
$ext_data = ReduxFramework_extension_multi_media::getExtendedData($id)

The return value will contain an array of the follow data in key/pair format:

  • id
  • title
  • filename
  • url
  • link
  • alt
  • author
  • description
  • caption
  • name
  • status
  • uploadedTo
  • date
  • modified
  • menuOrder
  • mime
  • type
  • subtype
  • icon
  • dateFormatted
  • nonces
  • editLink
  • sizes
  • width
  • height
  • fileLength
