gfpdf_current_form_object

Description​

This filter is useful if you want to manipulate the $form object specifically when a PDF is being processed. The filter is used in multiple locations throughout the code and, if needed, you can use $method to target to only modify $form during a specific class/function/method.

Parameters​

$form | array​

  • The Gravity Forms array

$entry | array​

  • The raw Gravity Forms Entry array.

$type | string​

  • The class/function/method the filter is being applied.
  • Valid options include:
    • initialize_pdf_class
    • get_form_data
    • get_core_template_styles
    • generate_html_structure
    • process_and_save_pdf
    • generate_pdf
    • trigger_post_save_pdf
    • get_pdf_display_list
    • get_active_pdfs
    • get_pdf_name
    • apply_backwards_compatibility_filters
    • helper_abstract_fields

Usage​

The following will reorder Gravity Forms fields in Core / Universal PDFs:

add_filter( 'gfpdf_current_form_object', function( $form, $entry, $type ) {
    if ( $type === 'generate_html_structure' ) {
      /* Move the 3rd and 4th fields to the end of the form for the PDF only */
      $extracted_fields = array_splice( $form['fields'], 2, 2 );
      $form['fields'] = array_merge( $form['fields'], $extracted_fields );
    }

    return $form;
}, 10, 3 );
