Yes, you can! 😉 Please check out filter wpda_after_simple_form:
https://wpdataaccess.com/2020/01/29/action-hook-wpda-after-simple-form-to-add-custom-elements-to-end-of-data-entry-forms/
Of course I wanted to test this for myself as well! 🙂 Below is the code to change the label to SAVE. Please be aware that this only works if you are in the Data Explorer (?page=wpda). If you want to use it on other pages, just add your menu slug.
<?php
function change_button_label( $self ) {
if ( isset( $_REQUEST['page'] ) && 'wpda' === $_REQUEST['page'] ) {
?>
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery('.button-primary').val('SAVE');
});
</script>
<?php
}
}
add_action( 'wpda_after_simple_form', 'change_button_label', 10, 1);
?>
Best regards,
Peter
