Automatically pull in CPT Post Titles into a select field

Hi @whyknott

I hope you’re well today and thank you for your question!

The code that you found is a good direction but you don’t really need it all. Here’s a bit different and modified version that should suit your needs just fine:

<?php

add_filter(
	'forminator_cform_render_fields',
	function( $wrappers, $form_id ) {

		$allowed_forms = array (
			1539,
		);

		if ( ! in_array( $form_id, $allowed_forms) ) {
			return $wrappers;
		}

		$select_fields_data = array(
			'select-1' => 'post',
			//'select-2' => 'CPT_2',
		);

		foreach ( $wrappers as $wrapper_key => $wrapper ) {
			if ( ! isset( $wrapper[ 'fields' ] ) ) {
				continue;
			}

			if ( 
				isset( $select_fields_data[ $wrapper[ 'fields' ][ 0 ][ 'element_id' ] ] ) &&
				! empty( $select_fields_data[ $wrapper[ 'fields' ][ 0 ][ 'element_id' ] ] )
			) {
				$posts = get_posts( array( 'post_type' => $select_fields_data[ $wrapper[ 'fields' ][ 0 ][ 'element_id' ] ] ) );

				if ( ! empty( $posts ) ) {
					$new_options = array();

					foreach( $posts as $post ) {
						$new_options[] = array(
							'label' => $post->post_title,
							'value' => $post->ID,
							'limit' => '',
							'key'   => forminator_unique_key(),
						);
					}

					$wrappers[ $wrapper_key ][ 'fields' ][ 0 ][ 'options' ] = $new_options;
				}
			}
		}

		return $wrappers;
	},
	10,
	2
);

And here’s how to use it:

1. create an empty file with a .php extension (e.g. “forminator-cpt-select.php”)
2. copy and paste that code into it
3. make following changes in code

a) in this part

$allowed_forms = array (
			1539,
		);

replace number 1539 with an ID of your form – it should be the same number that you see in form’s shortcode

b) here you set which select field should be filled with post titles (the select-1 in this case; replace with relevant select field ID of your form) and what post type (in this case I just used standard “post” but replace with name of your custom post)

'select-1' => 'post',

So for example if your select field is actually select-3 and post type is “models” this line would become

select-3 => 'models'

4. save the file and upload it to the “/wp-content/mu-plugins” folder of your site’s WordPress installation

And that’s it, it should work out of the box and once you visit the form you should see select field filled with post titles (and also options that you added to select field directly, when creating the field, so if you don’t need them, make sure to remove them by editing select field on form).

Hi @whyknott

Sorry for the delay here, it seems we didn’t receive notification for your responses.

As Adam said, we shouldn’t need the entire code, this is a clear version: https://gist.github.com/patrickfreitasdev/d7ad926561db4b598baeaf66478d790b

Line 6 was added a validation to match only the correct form:

https://gist.github.com/patrickfreitasdev/d7ad926561db4b598baeaf66478d790b#file-custom-select-options-php-L6

You can find your form ID when editing it.

Line 11 you will Select and post type: https://gist.github.com/patrickfreitasdev/d7ad926561db4b598baeaf66478d790b#file-custom-select-options-php-L11

Just be careful to enter the post type name as you defined i, you can find int the URL too https://monosnap.com/file/76OppyPovEK2EY7YNQ45zL35PHFX8w

However, this code should render the post type on Form load, in case you are looking to for example use one Select field to render the post data or a different post type the code needs some update.

Please, let us know if it got working now.

Hi @whyknott

The code would work with specifically defined post type only and specific form (as defined by ID in the code). The field ID is also important.

In other words, these three things must be set correctly and match actual case:

if( $model_id != 1441 ){ – form ID (as seen in form’s shortcode) here

'select-3' => 'post', – form field ID and post type accordingly here

if any of those settings don’t match the actual use case, it won’t work.

I understand that this is important issue but please note that this is a custom code that’s out of the scope of support and meant to do something that Forminator doesn’t do currently out of the box. This is a working code that, if set correctly and not conflicting with any other code/plugin – should work just fine.

If you need it to be expanded to, e.g. work with multiple forms and/or multiple post types at once, please consider hiring a developer that would further develop it for you.

Getting back to this particular version of the code: no, form does not have to be embedded on the very same post-type post. It can be embedded anywhere on site but what is important are those three settings that I mentioned above. Please double-check them all.

The code must also be correctly added to the site as MU plugin. Mu plugin is a file with a .php extension (e.g. forminator-pull-cpt.php) that contains this entire code and is uploaded to the “/wp-content/mu-plugins” folder of your site’s WordPress installation.

If it doesn’t work all together this way, please confirm here that the code is added that way and please share a link to the example page with the form in question on it so we could take a look.

Kind regards,
Adam

Hi @whyknott,

Does the $model_id variable name need to be something specific like an ACF field name or the name of the CPT?

The $model_id is form ID and it’s only passed in the code as an argument. So there shouldn’t be any change to its variable if you use CPT if it’s passed as an argument.

Could you please test whether it works if you try with “post”? This would help in determining whether the issue is specific to CPT or not too.

Also possible to share the final code that you are testing at the moment, so that we could see if there is any further that could be suggested?

Looking forward to your response.

Regards,
Nithin
