Le fichier php est:

<?php error_reporting(0); 
$server="localhost"; 
$user="root"; 
$password=""; 
$database="camouflage_studio"; 

$con = mysqli_connect($server,$user,$password,$database); 
if (mysqli_connect_errno()) 
    { 
    echo "Connection Error: " . mysqli_connect_error(); 
    } 
// Updation 
$stmt = $con->prepare("UPDATE 'personal_detail' SET Name = ?, CNIC = ?, Date = ?, Ocassion = ?, Address = ?, Phone_No = ?, Bride_Mobile = ?, Groom_Mobile = ?, Family_Mobile = ?, EMail = ?, Referring = ?, Share = ?, Permission = ? WHERE CNIC = ?"); 

$stmt->bind_param('ssssssiiissss', $_POST['name'], $_POST['cnic'], $_POST['booking-date'], $_POST['ocassion'], $_POST['address'], $_POST['phone-no'], $_POST['bride-mobile'], $_POST['groom-mobile'], $_POST['family-mobile'], $_POST['email'], $_POST['refering'], $_POST['share'], $_POST['permission'], $_POST['cnic']); 

if(mysqli_stmt_execute($stmt)) 
{ 
echo '<script language="javascript" type="text/javascript"> 
       alert("Record Updated Successfully"); 
       window.location = "admin.php"; 
     </script>'; 
} 
else 
echo "Prepare Error: ",$con->error;  //remove $con->error before making ONLINE THE CODE. 

$stmt->close(); 
$con->close(); 
?> 
<!DOCTYPE html> 
<html> 
<head> 
<title>Record Updation</title> 
</head> 

<body> 
</body> 
</html> 

Le problème est que quand j'appuyez sur la touche RECORD UPDATE afin que la mise à jour Fichier .php ouvert dans le navigateur et rien ne se passe. Aucune erreur ne s'affiche ni aucune mise à jour d'enregistrement.

Answer 1

Laissez-moi savoir comment celui-ci va

Aussi, utilisez stmt- $> erreur afin de suivre les erreurs SQL si une
