J'espère que vous pourrez m'aider car je planche sur ce sujet depuis 3 jours sans résultat
Voilà j'ai un formulaire d'authentification avec contrôle de saisie des data par jquery acheté sur le net.
J'ai donc un champ login et pass
Mais je n'arrive pas à transférer ces info dans une page PHP car la soumission du formulaire est interceptée par Jquery.
En tout cas c'est ce que je comprends au vu des commentaires
Voici le code :
<?php
$error = false;
// Lib to enable support for json_encode for php < 5.2.0 - remove if your version is 5.2.0 or upper
require('_errors/libError.php');
// If login form submitted
if (isset($_POST['a']))
{
$valid = false;
$redirect = isset($_REQUEST['redirect']) ? $_REQUEST['redirect'] : 'essai.php';
// Check fields
if (!isset($_POST['login']) or strlen($_POST['login']) == 0){
$error = 'Saisissez votre login SVP';
}
elseif (!isset($_POST['pass']) or strlen($_POST['pass']) == 0){
$error = 'Saisissez votre mot de passe SVP';
}
else
{
/*
* Do whatever here to check user login
*/
$valid = ($_POST['login'] == 'xxx' and $_POST['pass'] == 'xxx');
if (!$valid){
$error = 'Wrong user/password, please try again';
}
}
// Check if AJAX request
$ajax = (isset($_SERVER['HTTP_X_REQUESTED_WITH']) and strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');
// If user valid
if ($valid){
// Handle the keep-logged option
if (isset($_POST['keep-logged']) and $_POST['keep-logged'] == 1){
// Set cookie or whatever here
}
if ($ajax) {
header('Cache-Control: no-cache, must-revalidate');
header('Expires: '.date('r', time()+(86400*365)));
header('Content-type: application/json');
echo json_encode(array(
'valid' => true,
'redirect' => $redirect
));
exit();
}
else {
header('Location: '.$redirect);
exit();
}
} else
{
if ($ajax) {
header('Cache-Control: no-cache, must-revalidate');
header('Expires: '.date('r', time()+(86400*365)));
header('Content-type: application/json');
echo json_encode(array(
'valid' => false,
'error' => $error
));
exit();
}
}
}

</html>Jquery peut-il envoyer des data à php ?
Car je vois que la variable data contient { a: $('#a').val(), login: login, pass: pass }
Puis il y a cette histoire de json
Enfin tout ça pour dire que je suis perdu !!!!
Merci d'avance à ceux qui pourront m'aider
