Change URL when updating
Use this code to change the redirect URL when an entry is being updated.
add_filter('frm_redirect_url', 'return_page', 9, 3);
function return_page($url, $form, $params){
if(!isset($params['action'])){
$params['action'] = FrmAppHelper::get_param('frm_action');
}
if($form->id == 5 and $params['action'] == 'update'){ //change 5 to the id of your form
$url = 'http://example.com/redirect-page';
}
return $url;
}
Allow brackets in redirect URL
Some applications need to pass parameters like [6] in redirect URLs. This code example allows you to add brackets in your redirect URL.
add_filter( 'frm_redirect_url', 'partial_prepare_redirect_url', 1 );
function partial_prepare_redirect_url( $url ) {
remove_filter( 'frm_redirect_url', 'FrmEntriesController::prepare_redirect_url' );
return str_replace( array( ' ', '|', '@' ), array( '%20', '%7C', '%40' ), $url );
}
Allow ampersands in redirect URL
Use this code snippet to support ampersands from user input inside in your redirect URL.
add_filter( 'frm_redirect_url', 'replace_encoded_ampersand', 10, 2 );
function replace_encoded_ampersand( $url, $form ) {
$target_form_id = 727; // Change 727 to your form ID.
if ( $target_form_id === (int) $form->id ) {
$url = str_replace( '&', '&', $url );
}
return $url;
}
