我在PHP代码中使用$.ajax()...遇到了这个恼人的问题。我无法检索ajax函数发送的数据。
<?php
if ($_POST){
include 'Bdd_connexion.php';
$filiere = $_POST['filiere'];
/*$annee = $_POST['annee'];
$groupe = $_POST['groupe'];*/
$sql = "";
$query = $Conn->prepare("SELECT * FROM `Etudiant` WHERE `filiere` = '".$filiere."'");
$result = $query->execute();
if ($result)
echo "success";
$results = $query->fetchAll( PDO::FETCH_ASSOC );
foreach($results as $rows)
echo $rows['Nom'];
}else{
echo "No post";
}?>

$.ajax({
type: "POST",
url: "count.php",
data: dataString,
cache: false,
success: function(html){
$(".deletefasl").html(html);
}
});
您的数据字符串应为
var dataString = 'varibale='+ id;
或用户$ .post
$.post("filename.php", { var in php : var in jquery or javascript},
function(result){
}
});
