File Uploader

The File Uploader controller allows users to choose a file from the WordPress Media Library.

Demonstration

 
Handy::control( 'file-uploader', [
    'id'          => 'file_uploader_id',
    'section'     => 'layout_section',
    'label'       => esc_html__( 'File Uploader Control', 'textdomain' ),
    'description' => esc_html__( 'Description Here', 'textdomain' ),
    'placeholder' => esc_html__( 'Upload File Here', 'textdomain' ),
    'priority'    => 1
]);

TIP

Here's an example using the default parameter. Note the default value accepts only an attachment ID.

 
Handy::control( 'file-uploader', [
    'id'          => 'file_uploader_id',
    'section'     => 'layout_section',
    'default'     => 100,
    'label'       => esc_html__( 'File Uploader Control', 'textdomain' ),
    'description' => esc_html__( 'Description Here', 'textdomain' ),
    'placeholder' => esc_html__( 'Upload File Here', 'textdomain' ),
    'priority'    => 1
]);

TIP

Here's an example using extensions parameter. These are the list of allowed file extensions: pdf, doc, docx, ppt, pptx, pps, ppsx, odt, xls, xlsx and psd.

 
Handy::control( 'file-uploader', [
    'id'          => 'file_uploader_id',
    'section'     => 'layout_section',
    'default'     => 100,
    'label'       => esc_html__( 'File Uploader Control', 'textdomain' ),
    'description' => esc_html__( 'Description Here', 'textdomain' ),
    'placeholder' => esc_html__( 'Upload File Here', 'textdomain' ),
    'extensions'  => [ 'pdf', 'doc' ],
    'priority'    => 1
]);
