prefill numeric fields with data from the post

Hi @giandani

I hope you are doing well.

“If possible I would like the form the get that amount directly from a custom field of the article.”

From your description, I guess it is saved as a post meta value, in this case, we can create a custom code for it.

– Get the ID of your Post Meta, the easiest way for this is by inspecting the page: https://monosnap.com/file/B3PpBWoJKCcVb9IbCZsM7TTdbz7IRL

More about post meta: https://designmodo.com/wordpress-post-meta/

– Get your Number field ID https://monosnap.com/file/0upXUEWpDQZPzY0hFDGYJABbIum0mn

– Edit it and set the default value for this number field as 0.

– Place the below code using a mu-plugin:

<?php

add_filter( 'forminator_field_number_markup', function( $html, $id ) {

	$post_meta = (int) get_post_meta( get_queried_object_id(), 'field_name', true );

	if ( $post_meta && $id = 'forminator-field-number-1' ) {
		$html = str_replace( 'value="0"', 'value="' . $post_meta . '"', $html );
	}
	return $html;

}, 10, 2 );

You can find more about mu-plugin https://wpmudev.com/docs/using-wordpress/installing-wordpress-plugins/#installing-mu-plugins

Update the ‘field_name’ adding your cost field key
Update the forminator-field-number-1 by adding your number ID, for example if your number field is 5 it would be forminator-field-number-5.

Now when the form loads on your post/page it will use this custom post meta to populate the number field.

Hello @giandani ,

We haven’t heard from you for a while now, so it looks like you don’t have more questions for us.

Feel free to re-open this ticket if needed.

Kind regards

I haven’t had the occasion to test the fix…
I’ll let you know if I’ll need some more help on this.

Many thanks,
Giandani
