需要有關使用PDO在PHP中更新表單的幫助
[英]Need an help for Updating a form in PHP using PDO
問題描述
除int的BDid列外，所有列均采用TEXT格式。 Ive的代碼使用未聲明的語句可以平穩運行，但我想我將使用相同的數據和相同的表對其進行更新。
不返回任何錯誤，但不影響任何行。
代碼沒有收到任何錯誤，但是MySQL沒有更新
<?php
require 'database.php';
$id = null;
if ( !empty($_GET['id'])) {
$id = $_REQUEST['id'];
}
if ( null==$id ) {
header("Location: index.php");
}
if ( !empty($_POST)) {
// keep track validation errors with form fields
$first_nameError = null;
$sur_nameError = null;
$companyError = null;
$locationError = null;
$supervisorError = null;
$departmentError = null;
$job_descriptionError = null;
$hire_dateError =null;

$messageError = null;
// keep track post values
$first_name = $_POST['first_name'];
$sur_name = $_POST['sur_name'];

}
// update data the field in the database
if ($valid) {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE employee SET first_name = ?,sur_name = ?, company = ?, location = ?, supervisor = ?,
department= ?, job_description = ?, hire_date = ?, email = ?, message = ? WHERE id = ?";
$q = $pdo->prepare($sql);
$q->execute(array($id, $first_name, $sur_name, $company, $location, $supervisor, $department,$job_description, $hire_date, $email, $message));

看來您需要將執行行更改為此：
$ q-> execute（array（$ first_name，$ sur_name，$ company，$ location，$ supervisor，$ department，$ job_description，$ hire_date，$ email，$ message，$ id））;
我需要幫助，無需使用表單即可使用Ajax，PHP和mySQL將信息發送到服務器
