Hello @acrspf
Hope you’re doing well today!
Our SLS team has shared the below custom Snippet as a workaround.
<?php
add_action( 'wp_footer', 'wpmudev_calc_field_post_meta', 9999 );
function wpmudev_calc_field_post_meta() {
global $post;
if ( is_a( $post, 'WP_Post' ) && !has_shortcode( $post->post_content, 'forminator_form' ) ) {
return;
}
$calc_val = get_post_meta( $post->ID, 'number_1', true );
?>
<script type="text/javascript">
jQuery(document).ready(function($){
setTimeout(function() {
$('.forminator-custom-form').trigger('after.load.forminator');
},100);
$(document).on('after.load.forminator', function( e, form_id ) {
if ( e.target.id == 'forminator-module-6' ) { // Please change 6 to your form's ID.
var calc_val = '<?php echo get_post_meta( $post->ID, 'number_1', true );?>';
setTimeout(function(){
$('#calculation-1 input').val(calc_val).trigger('change');
},1000);
}
});
});
</script>
<?php
}
add_filter( 'forminator_field_calculation_calculable_value', 'wpmudev_calc_field_meta_val', 10, 3 );
function wpmudev_calc_field_meta_val( $formula, $prepared_data, $field_settings ) {
if ( $prepared_data['form_id'] != 6 ) { // Please change the form ID.
return $formula;
}
if ( $field_settings['element_id'] == 'calculation-1' ) {
$formula = get_post_meta( forminator_get_post_data( 'ID' ), 'number_1', true );
}
return $formula;
}
Notes about the Snippet:
– You will need to change the “Form ID 6” to your actual form ID on the line numbers 18 & 32.
– You will need to update the “calculation-1” field ID to the calculation field ID as per the calculation field ID on your form. (Lines 21 & 36)
– You will need to update the ACF field ID “number_1” to your ACF field ID on lines 9, 19 & 37.
Once you’ve updated the Snippet with the respective IDs, you can add it to the /wp-content/mu-plugins/ directory as a mu-plugin.
Here is a guide on how you can add a mu-plugin: https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins
I would suggest you make a full backup of the site or test the snippet on the staging site just for additional safety.
Hope this helps. Should you need any further help, please reply to this topic and we’ll be glad to assist you.
Kind Regards,
Saurabh
