How to set the Selection field options in Gravity form using code

What is Gravity form?

Gravity form is one of the most popular contact form plugin for WordPress websites.

Generally, we can set the choices of dropdown/selection field from the wordpress dashboard.

But in certain cases, we need to set these choices dynamically from a saparate data source.

add_filter('gform_pre_render_3', 'populate_job_posts');


function populate_job_posts($form) {
    foreach ($form['fields'] as &$field) {

if($field->cssClass == 'dynamic_choices'){


        $job_posts = get_posts(array(
            'post_type' => 'job',
            'numberposts' => -1,
            'post_status' => 'publish',
        ));

        $choices = array();

        foreach ($job_posts as $job_post) {
            $choices[] = array('text' => $job_post->post_title, 'value' => $job_post->ID);
        }

        <span class="php_comment">// Update the placeholder text for the dropdown field.</span>
        $field->placeholder = 'Applied For*';
        $field->choices = $choices;
    }
    }

    return $form;
}
