acf/save_post – send email only once the posttype is created

  • Hello,

    I am working with WordPress and ACF Pro Fields.
    I want to let users fill out some form, after submit, I want to receive an E-Mail with all the information the user put in AND a specific posttype should be created in the WordPress backend(draft) so I can review it and then publish ist.

    All this works perfectly fine!
    BUT when I updated the post, I receive a NEW E-Mail with the same information and the updated content, I don’t want that, how can I stop this?

    Here is my Code

    <?php acf_form(array(
                            'field_groups' => array('group_5fc8d223090ce'),
                            'form' => false,
                            'post_id' => 'new_post',
                            'new_post' => array(
                                'post_type' => 'my_posttype',
                                'post_status' => 'draft',
                                'post_content' => true,
                        )); ?>
                            <input type="submit" id="issubmitform" name="issubmitform"
                                   class="acf-button button button-primary button-large" value="Submit">

    My function:

    add_action('acf/save_post' , 'my_save_post');
    function my_save_post($post_id) {
    if( get_post_type($post_id) !== 'my_posttype' ) {
    add_filter( 'wp_mail_content_type', 'wpdocs_set_html_mail_content_type' );
       $name = get_field('my_acf_field', $post_id);
        $to = '[email protected]';
        $headers = "Content-Type: text/html;  charset=UTF-8";
        $subject = 'My Subject' . $name;
        $message = "This is the message"
        wp_mail($to, $subject, $message, $headers );
        remove_filter( 'wp_mail_content_type', 'wpdocs_set_html_mail_content_type' );
    function my_acf_save_post3($post_id) {
        if ($_POST['issubmitform'] === "Submit"){
            wp_redirect( ''  ); exit;
    add_action('acf/save_post', 'my_acf_save_post3', 20);

    I am sure I am just missing something, any help would be appreciated

  • I had the same “issue”.

    I created a work around with an extra ACF field which will be filled on the first time after saving. For sending the email i check if that field is filled. If its empty, its a new post otherwise its an updated post

    if(empty(field)) { send email + fill field }

  • check the post status and only send the email if it is draft.

  • Hi John
    Would you please explain how we can check the post status?
    I have exactly the same issue.

    After a form is submitted a new CPT-entry is made as draft.
    The email goes out to the client who has filled that form.
    After reviewing and publishing the post, the mail goes out for a second time.

    On submit I have a mail like “thank you, we will check and publish”.
    After publishing it would be great to have another mail like “your post is published now” … or at least not the same mail again.

    Thank you

  • For publishing the post you would not use an ACF hook, you would use the WP transition_post_status hook.

  • Hi John
    Thank you for helping me out.

    To make it more precise:

    I have a frontend form where anyone can add a post to a cpt.
    This post is saved as draft until the site-owner is publishing the post.

    After filling the form on frontend, a mail should go to the client with a thank you message that his post will be published if everyting is ok.

    Thats where I have used acf/save_post.

    This is my Code

    add_action('acf/save_post' , 'my_save_post', 20);
    function my_save_post($post_id) {
    	 // If not CPT, exit
        if( get_post_type($post_id) !== 'inserate' ) {
        add_filter( 'wp_mail_content_type', 'wpdocs_set_html_mail_content_type' );
    	// get custom fields (field group exists for content_form)
    	$name = get_field('name', $post_id);
        $email = get_field('email', $post_id); 
        $to = $email;
    	$headers = 'From: ' . $name . ' <' . $email . '>' . "\r\n";
        $subject = 'Thank you';
        $message = 'Thank you for submitting a post';
        wp_mail($to, $subject, $message, $headers );
        remove_filter( 'wp_mail_content_type', 'wpdocs_set_html_mail_content_type' );

    Now my question is, to just send this mail after submitting the form, but not after publishing. At the moment the action is fired multiple times and I need a check for the post status or something else.


  • You check the post status using get_post_status(), which will == ‘draft’ for a draft post.

  • Hoi John
    Thank you, that helped me alot and I have now managed it.
    My biggest mistake was, that I was not saving as draft but as pending.

    Thank you very much
