[英]PHP: Why mysqli_fetch_assoc() won't work? I am using mysqli_stmt_get_result()
[英]mysqli_fetch_assoc not working with mysqli_stmt_get_result
這是在我的網站上創建用戶的代碼...我的個人資料 img 需要一個 while 循環,所以我使用了此視頻代碼https://youtu.be/I4JYwRIjX6c的一部分但是當我去嘗試它時它給了我這個錯誤:
Fatal error: Uncaught TypeError: mysqli_fetch_assoc(): Argument #1 ($result) must be of type mysqli_result, bool given in C:\xampp\htdocs\WravyBike\Includes\functions.inc.php:152 Stack trace: #0 C :\xampp\htdocs\WravyBike\Includes\functions.inc.php(152): mysqli_fetch_assoc(false) #1 C:\xampp\htdocs\WravyBike\Includes\signup.inc.php(60): createUser(Object(mysqli ), 'test', 'test@gma...', '', 'test12') #2 {main} 拋出 C:\xampp\htdocs\WravyBike\Includes\functions.inc.php 上線 11
這是我的代碼:我遇到了問題:while ($row = mysqli_fetch_assoc($result)) & $result = mysqli_stmt_get_result($stmt);
$sql = "INSERT INTO users (usersName, usersEmail, usersTel, usersPwd) VALUES (?, ?, ?, ?);";
// $sql = "INSERT INTO users (usersName, usersEmail, usersTel, usersPwd) VALUES ('$name', '$email', '$tel', '$pwd');";
$stmt = mysqli_stmt_init($conn);
// mysqli_query($conn, $sql);
if (!mysqli_stmt_prepare($stmt, $sql)) {
header("location: ../signup.php?error=stmtfailed");
exit();
}
else{
$pwdHashed = password_hash($pwd, PASSWORD_DEFAULT);
mysqli_stmt_bind_param($stmt, "ssss", $name, $email, $tel, $pwdHashed);
mysqli_stmt_execute($stmt);
$result = mysqli_stmt_get_result($stmt);
while ($row = mysqli_fetch_assoc($result)) {
$userid = $row["usersId"];
$sql = "INSERT INTO profileimg (usersId, status) VALUES ('$userid', 1);";
$result = mysqli_query($conn, $sql);
header("Location: ../EditAccount.php");
}
mysqli_stmt_close($stmt);
header("location: ../signup.php?error=none");
exit();
}
$result = mysqli_stmt_get_result($stmt);
在這部分,$result 將有一個 bool 值(true)如果它成功插入記錄(false)如果它失敗。
如果要更新此“profileimg”表中的用戶狀態,請使用此代碼
$last_id = $conn->insert_id;
mysqli_stmt_bind_param($stmt, "ssss", $name, $email, $tel, $pwdHashed);
if (mysqli_stmt_execute($stmt)) {
$last_id = $conn->insert_id;
$sql = "INSERT INTO profileimg (usersId, status) VALUES ('$last_id', 1);";
$result = mysqli_query($conn, $sql);
header("Location: ../EditAccount.php");
}
