Description

Use this filter to dynamically change a field's value in Core and Universal templates before it gets wrapped in the final HTML markup. In the majority of cases this filter will be more useful than gfpdf_field_html_value. Be aware, section fields, page fields and the product table are not run through this filter.

Version

This filter was introduced in Gravity PDF 4.2.

Parameters

$value | string : The field's content to be included in the PDF

$field | array : The current field being processed

$entry | array : The Gravity Forms entry array

$form | array : The Gravity Forms array

$pdf_field | object : The current field helper class. See /src/helper/fields

Usage

The following code will prefix all values with a bullet point:

add_filter( 'gfpdf_pdf_field_content', function( $value, $field, $entry, $form ) {
	return '• ' . $value;
}, 10, 4 );

You can also target specific field types:

add_filter( 'gfpdf_pdf_field_content_text', function( $value, $field, $entry, $form ) {
	return '• ' . $value;
}, 10, 4 );

Or an individual field, targeted by ID:

add_filter( 'gfpdf_pdf_field_content', function( $value, $field, $entry, $form ) {
	if( $field->id === 20 ) {
		return '• ' . $value;
	}

	return $value;
}, 10, 4 );

Display each sub-field in an address field on a new line:

add_filter( 'gfpdf_pdf_field_content', function( $value, $field, $entry, $form, $pdf_field ) {
        if( $field->type === 'address' ) {
	    $content = $pdf_field->value();

            return implode( '<br>', array_filter( $content ) );
        }

	return $value;
}, 10, 5 );
