未捕獲異常'PDOException'錯誤我得到了這種錯誤,請有誰能幫我修復它。如果電子郵件重複或不在數據庫中,則在放置代碼以進行過濾之後,會出現錯誤。運行我的代碼後,我的pdo
這裏是我得到的錯誤:
<?php
$host = "localhost";
$user = "root";
$pass = "";
$db = "test";
$dbc = new PDO("mysql:host=" . $host . ";dbname=" . $db, $user, $pass);
$dbc->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$name = @$_POST['name'];
$age = @$_POST['age'];
$address = @$_POST['address'];
$gender = @$_POST['gender'];
$email = @$_POST['email'];
$dupesql = "SELECT * FROM students WHERE email = :email ";
$dupesql = $dbc->prepare($dupesql);
$dupesql->bindParam(':name', $email);
$dupesql->execute();
$num_rows = $dupesql->rowCount();
if($num_rows === 0)
{
echo "1";
$q = "INSERT INTO students(name, age, address, gender, email) VALUES(:name, :age, :address, :gender, :email)";
$query = $dbc->prepare($q);
$query->bindParam(':name', $name);
$query->bindParam(':age', $age);
$query->bindParam(':address', $address);
$query->bindParam(':gender', $gender);
$query->bindParam(':email', $email);
$results = $query->execute();
}else{
echo "0";
exit;
}
?>
'$ dupesql-> bindParam(':name',$ email);'?它應該':電子郵件' –
@ 1nflktd哦,謝謝我錯過了...把它放在回答,所以我可以投票 – user3762241
爲什麼你沒有發現異常?爲什麼在$ _POST前面有沉默操作符?你爲什麼使用bindParam而不是bindValue?你知道兩者的區別嗎? –
