J'essaie d'implémenter un bouton qui mettrait à jour une variable de session en utilisant ajax et l'événement onclick.
<?php
session_start();
?>

alert("XHR not created");

}
return req;
};
function storing(data, element)
{
element.innerHTML = data;
}
function submitForm(element)
{
var req = createInstance();
req.onreadystatechange = function()
{
if(req.readyState == 4)
{
if(req.status == 200)
{
storing(req.responseText, element);
}
else
{
alert("Error: returned status code " + req.status + " " + req.statusText);
}
}
};
req.open("GET", "ajax-get.php", true);
req.send(null);
}
</script>
</head>
<body>
<p> <span id="storage"> </span></p>
<form name="ajax" method="post" action="">
<p>
<input type="button" value="Envoyer" onclick="submitForm(document.getElementById('storage'))">
</p>
</form>
<?php
if(isset($_POST['download'])){
$_SESSION['stop_upload']=0;
echo $_SESSION['stop_upload'];
while($_SESSION['stop_upload']==0){
traitements
echo $_SESSION['stop_upload'];
}
echo $_SESSION['stop_upload'];
}
</body><?php
$_SESSION['stop_upload'] = 1;
echo $_SESSION['stop_upload'];
?>J'espère avoir été clair.
Merci d'avance pour vos aides et conseils.
PS : Je ne mets pas le code du formulaire qui me renvoi la méthode $_POST['download'] car sans importance pour mon problème.
