Contact Form 7 and Custom post type

Question

I want to use contact form 7 in Wordpress to build a order Form. I want the content of the order Form to be populated with content from a custom post type \"trade Show Mater

Answer 1

I do no think the wpcf7_form_tag works in the same way as vicente showed in his great answer before. It may have changed since 2015.

If you read here it explains how you need to use the wpcf7_form_tag: https://contactform7.com/2015/01/10/adding-a-custom-form-tag/

With that in mind along with this other post from Contact Form 7: https://contactform7.com/2015/02/27/using-values-from-a-form-tag/#more-13351

I came up with this code to create a custom dropdown list for a custom post type that I have.

add_action( 'wpcf7_init', 'custom_add_form_tag_customlist' );

function custom_add_form_tag_customlist() {
    wpcf7_add_form_tag( array( 'customlist', 'customlist*' ), 
'custom_customlist_form_tag_handler', true );
}

function custom_customlist_form_tag_handler( $tag ) {

    $tag = new WPCF7_FormTag( $tag );

    if ( empty( $tag->name ) ) {
        return '';
    }

    $customlist = '';

    $query = new WP_Query(array(
        'post_type' => 'CUSTOM POST TYPE HERE',
        'post_status' => 'publish',
        'posts_per_page' => -1,
        'orderby'       => 'title',
        'order'         => 'ASC',
    ));

    while ($query->have_posts()) {
        $query->the_post();
        $post_title = get_the_title();
        $customlist .= sprintf( '<option value="%1$s">%2$s</option>', 
esc_html( $post_title ), esc_html( $post_title ) );
    }

    wp_reset_query();

    $customlist = sprintf(
        '<select name="%1$s" id="%2$s">%3$s</select>', $tag->name,
    $tag->name . '-options',
        $customlist );

    return $customlist;
}

Then you use the tag in contact form 7 like this.

[customlist your-field-name]

Hopefully this helps someone else who was looking for a way to do this like I was.

You could alter it to get any information you need from the custom post type.

It does not have any validation though.

Answer 2

Maybe you can use the wpcf7_form_tag filter hook for this.

If you want to use a custom post type as the options of a dropdown (select) you can add something like the example below in your functions.php:

function dynamic_field_values ( $tag, $unused ) {

    if ( $tag['name'] != 'your-field-name' )
        return $tag;

    $args = array (
        'numberposts'   => -1,
        'post_type'     => 'your-custom-post-type',
        'orderby'       => 'title',
        'order'         => 'ASC',
    );

    $custom_posts = get_posts($args);

    if ( ! $custom_posts )
        return $tag;

    foreach ( $custom_posts as $custom_post ) {

        $tag['raw_values'][] = $custom_post->post_title;
        $tag['values'][] = $custom_post->post_title;
        $tag['labels'][] = $custom_post->post_title;

    }

    return $tag;

}

add_filter( 'wpcf7_form_tag', 'dynamic_field_values', 10, 2);

In your form you can add the field:

[select* your-field-name include_blank]

In the example above the post_title is used in the options of the dropdown. You can add your own fields here (name, number, description, photo).
