Gravity Forms – Filter button so it supports icons

// filter the Gravity Forms button type
add_filter("gform_submit_button", "form_submit_button", 10, 2);
function form_submit_button($button, $form){
// The following line is from the Gravity Forms documentation - it doesn't include your custom button text
// return "<button class='button' id='gform_submit_button_{$form["id"]}'>'Submit'</button>";
// This includes your custom button text:
return "<button class='button' id='gform_submit_button_{$form["id"]}'>{$form['button']['text']}</button>";
// Oops this strips important stuff

// This try reveals my use case: I was actually trying to add a pseudo element to the input button
// This leaves the <input> as is, but prepends a span element
add_filter("gform_submit_button", "form_submit_button", 10, 2);
function form_submit_button($button, $form){
return "<span></span>".$button;
// This kinda works for my purpose but is really not ideal

// This is what I settled on
// Change Gravity Forms submit input to a button element
add_filter( 'gform_submit_button', 'form_submit_button', 10, 5 );
function form_submit_button ( $button, $form ){
$button = str_replace( "input", "button", $button );
$button = str_replace( "/", "", $button );
$button .= "{$form['button']['text']}</button>";
return $button;
// It's not perfect - it leaves some inapplicable attributes in the element
// but I can live with that to avoid a whole bunch more str_replace
// and it leaves the important onclick and tab index intact
