Populate ACF select field options with Gravity Forms to select a specific form

Thank you very much! It does exactly what I need but I have one remaining question: How would I be able to have a first (default) selection that is empty, so I can have no form when none is selected? Basically I need the FIRST select option to be "None", defaulted to the value 0 ...
THANKS so much!

You can add something like:
$choices[ $form->id ] = 'Select a form';
Before the "foreach" loop.

This is very elegant. Thanks a lot!

This is great, such a simple solution I thought I'd be trying to figure this out all night. Thanks!

I just come here to say thanks 👍

Could somebody explain how this works?

I've added the code to functions.php and I was expecting to see a "Gravity Forms" option in the field type selector.

Thanks.

[edit] I've worked out how it's done. Just use a normal ACF 'Select' field. Then add this field's field name after "/load_field/" in the add_filter call.

Glad you found the solution @KingWebsites, and thank you for sharing it!

Thanks. And you can use this if you'd like to use this function in a exported PHP file:

if (class_exists('GFFormsModel')) {
    $choices = [];
    foreach (\GFFormsModel::get_forms() as $form) {
        $choices[$form->id] = $form->title;
    }
}

acf_add_local_field(array(
    'key' => 'contact_form',
    'label' => 'Contact form',
    'name' => 'contact_form',
    'type' => 'select',
    'instructions' => '',
    'required' => 0,
    'conditional_logic' => 0,
    'choices' => $choices,
    'default_value' => array(),
    'allow_null' => 0,
));

Great solution! How do i display the selected form on my page? The value from the select box is the form ID.

Thank you psaikali! This was so helpful for me. I was getting a php warning (running php 8+) with the original code, so I'm offering this version that worked for me.

*Note to others: remember to change 'your_field_name' to whatever you named your ACF Select field.

// Populate ACF select field options with Gravity Forms forms 
function acf_populate_gf_forms_ids( $field ) {
    if ( class_exists( 'GFFormsModel' ) ) {
        $choices = array(
            'none' => 'None'
        );

        $forms = \GFFormsModel::get_forms();

        if ( $forms ) {
            foreach ( $forms as $form ) {
                $choices[ $form->id ] = $form->title;
            }
        }

        $field['choices'] = $choices;
    }

    return $field;
}
add_filter( 'acf/load_field/name=your_field_name', 'acf_populate_gf_forms_ids' );

Here's the PHP code to render the shortcode:

<?php 
	$form_id = get_field('your_field_name');
	if ($form_id && $form_id !== 'none') {
	    $escaped_form_id = acf_esc_html($form_id);
	    echo do_shortcode("[gravityform id=\"$escaped_form_id\" title=\"true\" description=\"true\" ajax=\"true\" tabindex=\"4\" theme=\"gravity\"]");
	}
?>

*Edited to set the default field to "none"
