将数据发送到php文件的表单如下：

<center>
<form action="update.php" method="post">
<fieldset style="width:50%"><legend>Please do the required changes</legend><br>
<label for="Name">Name :<br></label><input name="name" type="text" size="20" maxlength="40" value="<?php echo $data2[Name]?>"><br>

<!-- To center the button i'm embedding the buttons in a paragraph with an id as well. the id is used for CSS in head -->
<p id="btn">
<input type="submit" value="Update Record" name="submit_display_data_form" style="font-size:16px"></p>
</fieldset>
</form>
</center>
</body>
</html>

php文件是：

<?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>

问题是，当我按下UPDATE RECORD按钮时，只在浏览器中打开update.php文件，没有任何反应。既不会显示错误也不会记录更新。

Answer 1

2件事，Date是一个mysql保留字功能。为了将该单词作为col名称传递，您需要将其包含在反引号中。 Seconde的问题是反引号是“不是”。（注意差异？）

Base String :"YHKKGFFADGIJJ"
Search String:"ADGFFF"

Output:"ADG"

让我知道这个怎么回事

另外，使用$ stmt-＆gt;错误来跟踪sql错误（如果有的话）

按下UPDATE按钮时没有任何反应。使用准备好的陈述
