Bonsoir je solicite une nouvelle fois votre aide...
j'aimerais savoir si dans le code html de ma page contact il manque une ligne pour "appeler" mon fichier sendmail.php? Je vous joins les 2 scripts
Merci à vous

<section id="contact" class="s-contact target-section">

        <div class="overlay"></div>

        <div class="row narrow section-intro">
            <div class="col-full">
                <h3>Contact</h3>
                <h1>Bonjour </h1>
                
                <p class="lead">Si vous souhaitez me contacter utilisez le formulaire ci-dessous . Merci..</p>

non, il ne manque pas de ligne. elle est bien là :
<form name="contactForm" id="contactForm" method="post" action="mailto:--------------------">
après, comme il n'y a pas sendmail.php dedans, ça va marcher beaucoup moins bien.
