我已经设置了代码并使用数据库进行查询。我认为 PDO 连接到 MySQL 的一切都是正确的,但记录没有进入数据库。
//包括开始 //连接
<?php
$DSN = 'mysql:host = localhost; dbname = cms4.2.1';
$ConnectingDB = new PDO($DSN, 'root', '');
?>
//重定向函数
<?php
function Redirect_to($New_Location) {
header("Location:".$New_Location);
exit;
}
?>
//错误处理
<?php
session_start();
function ErrorMessage(){
if (isset($_SESSION["ErrorMessage"])){
$Output = "<div class=\"alert alert-danger\">";
$Output .= htmlentities($_SESSION["ErrorMessage"]);
$Output .= "</div>";
$_SESSION["ErrorMessage"] = null;
return $Output;
}
}
function SuccessMessage() {
if (isset($_SESSION["SuccessMessage"])) {
$Output = "<div class=\"alert alert-success\">";
$Output .= htmlentities($_SESSION["SuccessMessage"]);
$Output .= "</div>";
$_SESSION["SuccessMessage"] = null;
return $Output;
}
}
?>
//包含结束
//代码
<?php require_once("Includes/DB.php"); ?>
<?php require_once("Includes/Functions.php"); ?>
<?php require_once("Includes/Sessions.php"); ?>
<?php
if (isset($_POST["Submit"])) {
$Category = $_POST["CategoryTitle"];
$Admin = "Abdullah";
date_default_timezone_set("Asia/Riyadh");
$CurrentTime = time();
$DateTime = strftime("%B-%d-%Y %H:%M:%S", $CurrentTime);
if (empty($Category)) {
$_SESSION["ErrorMessage"] = "All fields must be filled out";
Redirect_to("Categories.php");
} else if (strlen($Category) < 3) {
$_SESSION["ErrorMessage"] = "Category is short";
Redirect_to("Categories.php");
} else if (strlen($Category) > 49) {
$_SESSION["ErrorMessage"] = "Category is too long";
Redirect_to("Categories.php");
} else {
// Insert to database
// The problem starts here I think
global $ConnectingDB;
$sql = "INSERT INTO category(title,author,datetime)";
$sql .= "VALUES(:categoryName,:adminName,:dateTime)";
$stmt = $ConnectingDB->prepare($sql);
$stmt -> bindValue(':categoryName',$Category);
$stmt -> bindValue(':adminName',$Admin);
$stmt -> bindValue(':dateTime',$DateTime);
$Execute = $stmt -> execute();
if ($Execute) {
$_SESSION["SuccessMessage"] = "Category Added Successfully";
Redirect_to("Categories.php");
} else {
$_SESSION["ErrorMessage"] = "Something went wrong";
Redirect_to("Categories.php");
}
}
}
?>
执行消息始终保留“出现问题”
当我进入正常的 MySQL 查询系统时,一切正常。但我想完成 PDO 方面的工作。
最佳答案
我认为你可以使用pdoexception
然后您将能够打印您的错误和异常。
try{
$stmt = $ConnectingDB->prepare($sql);
$stmt -> bindValue(':categoryName',$Category);
$stmt -> bindValue(':adminName',$Admin);
$stmt -> bindValue(':dateTime',$DateTime);
$Execute = $stmt -> execute();
}catch( PDOException $e ) {
print $e->getMessage();
}
pdo should i try/catch every query?
希望对您有帮助。
