Nous espérions avoir de nouveaux yeux à ce sujet. J'ai une page qui va ajouter un nouvel événement à une base de données. Tous les 3 champs sont obligatoires, donc s'ils sont vides lorsque le bouton Soumettre est appuyé, le message d'erreur devrait apparaître. Quelqu'un sait pourquoi il ne montre pas le message d'erreur? Merci d'avance!Message d'erreur de validation de formulaire ne pas afficher

<h1>New Event</h1>
<p>
As an admin you have the right to create a new event. Simply fill out the form below and hit submit.
</p>
<?php
// creates the new record form
// since this form is used multiple times in this file, I have made it a function that is easily reusable
function renderForm($name, $date, $location, $error22)
{
?>
<?php
// if there are any error22s, display them
if ($error22 != '') {
echo '<div style="padding:4px; border:1px solid red; color:red;">' . $error22 . '</div>';
}
?>
<form action="" method="post">
<div>
Name:
<input type="text" name="name" value="<?php echo $name;?>" />
<br/>
Date:
<input type="text" name="date" value="<?php echo $date;?>" />

Location:
<input type="text" name="location" value="<?php echo $location;?>" />

<input type="submit" name="submit_event" value="Submit">
</div>
</form>
<?php
}
// connect to the database
include ("home_connection.php");
// check if the form has been submitted. If it has, start to process the form and save it to the database
if (isset($_POST['submit']))
{
// get form data, making sure it is valid
$name = mysql_real_escape_string(htmlspecialchars($_POST['name']));
$date = mysql_real_escape_string(htmlspecialchars($_POST['date']));
$location = mysql_real_escape_string(htmlspecialchars($_POST['location']));
// check to make sure all fields are entered
if ($name == '' || $date == '' || $location == '')
{
// generate error22 message
$error22 = 'error22: Please fill in all required fields!';
// if either field is blank, display the form again
renderForm($name, $date, $location, $error22);
}
else
{
// save the data to the database
mysql_query("INSERT events SET name='$name', date='$date', location='$location'")

Je suggère de séparer PHP de HTML pour une meilleure compréhension. –
Essayez de répercuter les variables après que le formulaire a été soumis pour voir si elles contiennent bien quelque chose. Et vous pouvez toujours remplacer 'if ($ name == '' ||' etc par 'if (strlen ($ name) <1 ||' etc juste pour voir si cela fonctionne. – James
