frm_sanitize_shortcodes

Last Updated: June 7, 2018

Knowledge Base → Extend Formidable Forms → Formidable Hooks - for Developers → Field Options and Values → frm_sanitize_shortcodes
Heads up!
This article contains PHP code and is intended for developers. We offer this code as a courtesy, but don't provide support for code customizations or 3rd party development.

This hook allows shortcodes in field values to be processed rather than shown on the page.

Formidable Forms is the best WordPress Form Builder plugin. Get it for free!

Added security protections prevents shortcodes inside a field from being processed in user-submitted data. If you would like to opt-out of this protection, you can use this filter.

Usage

add_filter( 'frm_sanitize_shortcodes', 'maybe_allow_user_shortcodes', 10, 2 );

Parameters

  • $sanitize (boolean) - return true if shortcodes should be secure
  • $atts (array)
    • $atts['entry'] (object)
    • $atts['value'] (string) - the user-submitted value

Examples

Process all shortcodes in all fields

add_filter( 'frm_sanitize_shortcodes', '__return_false' );

Allow the [gallery] shortcode

Only return true is a specific shortcode is included in the field value.

add_filter( 'frm_sanitize_shortcodes', 'maybe_allow_user_shortcodes', 10, 2 );
function maybe_allow_user_shortcodes( $sanitize, $atts ) {
  if ( strpos( $atts['value'], '[gallery' ) !== false ) {
    $sanitize = false;
  }
  return $sanitize;
}
