Description
By default, the PDF generated by the Gravity Flow PDF Generator Extension is deleted immediately after sending by email – this helps to ensure that unauthorized users don’t see fields values later on in the workflow. The gravityflowpdf_delete_post_send filter can be used to prevent the PDF file from being deleted when it is sent by email.
Parameters
| Parameter | Type | Details |
|---|---|---|
| $delete_pdf | Boolean | Whether to delete the PDF after sending by email. |
| $form | Array | The form array |
| $entry | Array | The entry array |
| $step | Step | The PDF step. |
Examples
Retain the PDF on the server after sending by email only for form ID 1.
add_filter( 'gravityflowpdf_delete_post_send', function( $delete_pdf, $form, $entry, $step ) {
if ( $form['id'] == 1 ) {
$delete_pdf = false;
}
return $delete_pdf;
} );
Always retain the PDF file on the server after sending by email regardless of the form or step.
add_filter( 'gravityflowpdf_delete_post_send', '__return_false' );
Since
This filter was added in version 1.3.
