PHP SQL不会更新数据
截至2015年6月23日更新
更新查询仍无效。从Rene Kross那里得到了一些建议并进行了一些代码清理，偶然发现了一些缺少分号等的部分，但是更新查询仍无法正常工作。
这是adminUpdate.php
<?php
require 'Connect.php';
$staffID = null;
if ( !empty($_GET['staffID'])) {
$staffID = $_REQUEST['staffID'];
}
if ( null==$staffID ) {
header("Location: ManageAdministrator.php");
}
if ( !empty($_POST)) {
// keep track validation errors
$adminNameError = null;
$emailError = null;
$SKGError = null;
$ExtnError = null;
// keep track post values
$adminName = $_POST['adminName'];
$email = $_POST['email'];
$SKG = $_POST['SKG'];
$Extn = $_POST['Extn'];
// validate input
$valid = true;
if (empty($adminName)){
$adminNameError = "Please enter Administrator Name";
$valid = false;
}
if (empty($email)) {
$emailError = 'Please enter Email Address';
$valid = false;
} else if ( !filter_var($email,FILTER_VALIDATE_EMAIL) ) {
$emailError = 'Please enter a valid Email Address';
$valid = false;
}
if (empty($SKG)) {
$SKGError = 'Please choose SKG';
$valid = false;
}
if(empty($Extn)){
$ExtnError = "Please enter Extension Number";
$valid = false;
}
// update data
if ($valid) {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE admin set adminName ='$adminName', email ='$email', SKG ='$SKG', Extn ='$Extn' WHERE staffID = '$staffID'";
$q = $pdo->prepare($sql);
$q->execute(array($staffID,$adminName,$email,$SKG,$Extn));
Database::disconnect();
header("Location: ManageAdministrator.php");
}
} else {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "SELECT * FROM admin where staffID = ?";
$q = $pdo->prepare($sql);
$q->execute(array($staffID));
$data = $q->fetch(PDO::FETCH_ASSOC);
$adminName = $data['adminName'];
$email = $data['email'];
$SKG = $data['SKG'];
$Extn = $data['Extn'];
$password = $data['password'];
Database::disconnect();
}
?>

这是Connect.php
<?php
class Database
{
private static $dbName = 'tlad' ;

private static $dbUsername = 'root';
private static $dbUserPassword = '';
private static $cont = null;
public function __construct() {
exit('Init function is not allowed');
}
public static function connect()
{
// One connection through whole application
if ( null == self::$cont )
{
try
{
self::$cont = new PDO( "mysql:host=".self::$dbHost.";"."dbname=".self::$dbName, self::$dbUsername, self::$dbUserPassword);
}
catch(PDOException $e)
{
die($e->getMessage());
}
}
return self::$cont;
}
public static function disconnect()
{
self::$cont = null;
}
}
?>
这是我的表：
正如我前面提到的，read，create和delete函数正在工作，除了这个更新函数不是。
请注意：我已经按照有关创建CRUD数据表的教程，虽然他的模板有效，但我的代码却没有。这是教程的更新模板代码：
<?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
$nameError = null;
$emailError = null;
$mobileError = null;
// keep track post values
$name = $_POST['name'];
$email = $_POST['email'];
$mobile = $_POST['mobile'];
// validate input
$valid = true;
if (empty($name)) {
$nameError = 'Please enter Name';
$valid = false;
}
if (empty($email)) {
$emailError = 'Please enter Email Address';
$valid = false;
} else if ( !filter_var($email,FILTER_VALIDATE_EMAIL) ) {
$emailError = 'Please enter a valid Email Address';
$valid = false;
}
if (empty($mobile)) {
$mobileError = 'Please enter Mobile Number';
$valid = false;
}
// update data
if ($valid) {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE customers set name = ?, email = ?, mobile =? WHERE id = ?";
$q = $pdo->prepare($sql);
$q->execute(array($name,$email,$mobile,$id));
Database::disconnect();
header("Location: index.php");
}
} else {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "SELECT * FROM customers where id = ?";
$q = $pdo->prepare($sql);
$q->execute(array($id));
$data = $q->fetch(PDO::FETCH_ASSOC);
$name = $data['name'];
$email = $data['email'];
$mobile = $data['mobile'];
Database::disconnect();
}

1 个答案:
答案 0 :(得分：3)
您的execute有5个参数，但查询需要6个。
$sql = "UPDATE admin set staffID = ?, adminName = ?, email = ?, SKG = ?, Extn = ? WHERE staffID = ?";
$q = $pdo->prepare($sql);
$q->execute(array($staffID, $adminName, $email, $SKG, $Extn, $staffID));
在$，email和SKG前面也遗漏了Extn。
