Pour leformulaire:

Etincluez uneentrée cachée quiindique à WP quelleest lafonction avec laquelle vous allez letraiter:

 <input type="hidden" name="action" value="my_contact_form">
 

Écrivez lafonction dansfunctions.php:

 function my_contact_form_func(){

    if ( ! empty( $_POST ) ) {
        // do your thing
    }
}
 

Dites à WP quelleest lafonction:

 add_action( 'admin_post_nopriv_my_contact_form', 'my_contact_form_func' );
add_action( 'admin_post_my_contact_form', 'my_contact_form_func' );
 

Alternatively you could post it to WP and handle the processing in functions.php.

For the form:

action="<?php echo esc_url( admin_url('admin-post.php') ); ?>"

And include a hidden input which tells WP what is the function with which you'll be processing it:

<input type="hidden" name="action" value="my_contact_form">

Write the function in functions.php:

function my_contact_form_func(){

    if ( ! empty( $_POST ) ) {
        // do your thing
    }
}

Tell WP what is the function:

add_action( 'admin_post_nopriv_my_contact_form', 'my_contact_form_func' );
add_action( 'admin_post_my_contact_form', 'my_contact_form_func' );
