Redirection formulaire après vérification

Bonjour,

J'ai besoin de votre aide car je souhaiterais rajouter une option au bouton d'envoi de mon formulaire une option me permettant de rediriger l’utilisateur après quand il clique sur le bouton. J'aimerais en fait que les informations du formulaire soient valides (adresse e-mail valide, par exemple) et que seulement dans ce cas, l’utilisateur soit redirigé. Comme ça, je suis sûr que le formulaire a bien été soumis avant qu'il passe à l'autre page. Et donc, si les informations entrées ne sont pas valides, le message d'erreur pré-configuré apparaisse.

Voilà le code php principal du formulaire :

<?php
/**


* Vendor Registration Form Template * * @version 2.0.0 */ if ( ! defined( 'ABSPATH' ) ) {    exit; // Exit if accessed directly}?> <h2><?php esc_html_e( 'Vendor Registration Form', 'woocommerce-product-vendors' ); ?></h2> <p><?php esc_html_e( 'Submit the form below to become a vendor on this store.', 'woocommerce-product-vendors' ); ?></p> <form class="wcpv-shortcode-registration-form">     <?php do_action( 'wcpv_registration_form_start' ); ?>     <?php if ( ! is_user_logged_in() ) { ?>        <p class="form-row form-row-first">            <label for="wcpv-firstname"><?php esc_html_e( 'First Name', 'woocommerce-product-vendors' ); ?> <span class="required">*</span></label>            <input type="text" class="input-text" name="firstname" id="wcpv-firstname" value="<?php if ( ! empty( $_POST['firstname'] ) ) echo esc_attr( trim( $_POST['firstname'] ) ); ?>" tabindex="1" />        </p>         <p class="form-row form-row-last">            <label for="wcpv-lastname"><?php esc_html_e( 'Last Name', 'woocommerce-product-vendors' ); ?> <span class="required">*</span></label>            <input type="text" class="input-text" name="lastname" id="wcpv-lastname" value="<?php if ( ! empty( $_POST['lastname'] ) ) echo esc_attr( trim( $_POST['lastname'] ) ); ?>" tabindex="2" />        </p>                 <div class="clear"></div>                 <p class="form-row form-row-wide">            <label for="wcpv-username"><?php esc_html_e( 'Login Username', 'woocommerce-product-vendors' ); ?> <span class="required">*</span></label>            <input type="text" class="input-text" name="username" id="wcpv-username" value="<?php if ( ! empty( $_POST['username'] ) ) echo esc_attr( trim( $_POST['username'] ) ); ?>" tabindex="3" />        </p>         <p class="form-row form-row-first">            <label for="wcpv-email"><?php esc_html_e( 'Email', 'woocommerce-product-vendors' ); ?> <span class="required">*</span></label>            <input type="email" class="input-text" name="email" id="wcpv-email" value="<?php if ( ! empty( $_POST['email'] ) ) echo esc_attr( trim( $_POST['email'] ) ); ?>" tabindex="4" />        </p>         <p class="form-row form-row-last">            <label for="wcpv-confirm-email"><?php esc_html_e( 'Confirm Email', 'woocommerce-product-vendors' ); ?> <span class="required">*</span></label>            <input type="email" class="input-text" name="confirm_email" id="wcpv-confirm-email" value="<?php if ( ! empty( $_POST['confirm_email'] ) ) echo esc_attr( trim( $_POST['confirm_email'] ) ); ?>" tabindex="5" />        </p>         <?php } ?>         <div class="clear"></div>     <p class="form-row form-row-wide">        <label for="wcpv-vendor-vendor-name"><?php esc_html_e( 'Vendor Name', 'woocommerce-product-vendors' ); ?> <span class="required">*</span></label>        <input class="input-text" type="text" name="vendor_name" id="wcpv-vendor-name" value="<?php if ( ! empty( $_POST['vendor_name'] ) ) echo esc_attr( trim( $_POST['vendor_name'] ) ); ?>" tabindex="6" />        <em class="wcpv-field-note"><?php esc_html_e( 'Important: This is the name that customers see when purchasing your products.

Et voilà le code php complémentaire au formulaire (sachant que j'ai déjà essayé de le modifier mais je ne vois pas les modifications apparaître sur le site qui est un site wordpress) :

<?php
if ( ! defined( 'ABSPATH' ) ) {
 exit; // Exit if accessed directly
}
