Creating a contact form

With the help of the MB Frontend Submission extension from Meta Box, you can easily create forms for users to submit their posts from the frontend. Let’s see how it does!


To get started, we need the Meta Box core plugin to have the framework for creating custom fields. It’s free, so you can download it directly from

For the advanced features from Meta Box, we need some of its extensions:

1. Creating a custom post type

Each contact submitted in the form will be saved in a post of a custom post type. So, let’s create one. Go to Meta Box > Post Types > Add New.

Create a custom post type

Then, move to the Supports tab, choose only Title

Choose only Title option

After that, you will see a new Contacts menu in the admin dashboard.

2. Creating custom fields

Go to Meta Box > Custom Fields to create a new field group.

Create custom fields

Since a contact form will have some information such as contact’s name, contact email, message and so on, I created the fields as below:

Contact form information

After creating all the fields, move to the Settings tab, choose the Location as Post type and select Contacts to apply these fields to it.

Set location for the created fields

Pay attention to the ID of the field group since we’ll use it in the next step.

3. Displaying contact form on the frontend

Go to Pages > Add New to create a new page named Contact Us.

Created a new page

Go back to Meta Box > Custom Fields, you’ll see the shortcodes column will be there. Just copy the shortcode of the field group you want to use for the contact form.

Copy the shortcode

It’ll be in the form like this:

[mb_frontend_form id='contact-form' post_fields='title,content']

In there, contact_form is the ID of the field group that we created in the previous step.

This shortcode is automatically generated after publishing the field group due to the help of MB Frontend Submission. Just paste it to anywhere you want to display your form. You also can edit the shortcode a little bit by adding/removing some attributes to customize your form.

Here, I don’t want to show the title and content fields so I deleted the post_fields='title,content' attribute as follow:

Delete the attribute

Now, go to the page in the frontend and you'll see the form with the custom fields as we created:

The form with the created custom fields

Just fill in some information and click the Submit button.

Now, go to the admin dashboard > Contacts and you'll see your test message is there as a post. Open the post editor will show you full contact message:

Full contact message

Your contact form is ready for use. However, I want to see the details of the submitted contacts directly in the admin dashboard, so I will show them as columns in the next step.

4. Showing contact information in the admin column

To have a page listing all the contacts information in the admin dashboard, you need the help of the MB Admin Columns extension. Go back to the created custom field group, and set up for each field.

For example, choose the Your Name field and tick the Show as an admin columns option. Then, there are additional settings to set up for the position and title of the column as below:

Contact information in the admin column

With the Replace option, you can choose to replace the Title column with Your Name field. And, it will display as follow:

Replace the Title column with Your Name field

For other information such as Your Email field, also tick to show it as an admin column. Then, choose Column position as After and then fill in your_name in the beside box. your_name is the ID of the Your Name field.

Choose Column position as After

And then, you’ll see it displayed as a column after the From column.

Form column

For the remaining fields, do likewise.

Do likewise with the remaining fields

The remaining fields

Now, go to the Contacts post type and you’ll see a better list for easier management.

5. Sending email notification

If you want to send the contacts to your email right after it’s submitted, follow this step.

We need some coding now. We'll use the hook rwmb_frontend_after_process to run our custom code to send an email. This has been documented quite well here.

Add this following code to the functions.php file:

add_action( 'rwmb_frontend_after_process', function( $config, $post_id ) {
if ( 'contact-form' !== $config['id'] ) {
$email = rwmb_meta( 'your_email', '', $post_id );
$name = rwmb_meta( 'your_name', '', $post_id );
$subject = rwmb_meta( 'subject', '', $post_id );
$message = rwmb_meta( 'message', '', $post_id );
$body = "<p>Name: $name</p>
<p>Email: $email</p>
<p>Subject: $subject</p>
<p>Message: $message</p>";

$headers = ['Content-type: text/html', "Reply-To: $email"];
wp_mail( '', 'New contact message', $body );
}, 10, 2 );

Add the code


  • your_email, your_name, subject, message: these are the ID of the created custom fields;
  • replace this with any email that you want to receive the notification about the contact submission.

From now on, whenever someone submits the form, you will see a new contact in both the admin and a new email in your inbox. That’s done!
