努力更新一行我知道我通过再次var_dump() $ _POST来发布正确的值，但它必须是我用来更新表格的方法：
<?php
/******************************************************************
** ACTION SCRIPT TO UPDATE THE CATEGORY AFTER CHANGES ARE MADE **
******************************************************************/
if(isset($_POST["submit"])){
include_once'../../config.php';
try {
$dbh = new PDO("mysql:host=localhost;dbname=dashboardr",$username,$password);
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE cat_list SET cat_title = :cat_title, cat_color = :cat_color, cat_icon = :cat_icon WHERE cat_id = :cat_id";
$query = $dbh->prepare($sql);
$query->execute(array(":cat_title"=>$_POST["cat_title"],
":cat_color"=> $_POST["cat_color"]),
":cat_icon"=> $_POST["cat_icon"]),
":cat_id"=> $_POST["cat_id"]));
if ($query) {
header ('Location: ../list_cat.php?success=2');
}
else{
}
$dbh = null;
}
catch(PDOException $e)
{
echo $e->getMessage();
}
}
?>
以下是表格：
<?php include 'header.php'; ?>
<?php
require_once '../../db_con.php';
if(!empty($_GET['cat_id'])){
$cat = intval($_GET['cat_id']);
try{
$results = $dbh->prepare('SELECT * FROM cat_list WHERE cat_id = ?');
$results->bindParam(1, $cat);
$results->execute();
} catch(Exception $e) {
echo $e->getMessage();
die();
}
$cat = $results->fetch(PDO::FETCH_ASSOC);
if($cat == FALSE){
echo '<div class="container">';
echo "<img src='../img/404.jpg' style='margin: 40px auto; display: block;' />";
echo "<h1 style='margin: 40px auto; display: block; text-align: center;' />Oh Crumbs! You upset the bubba!</h1>";
echo '<a href="userList.php" style="margin: 40px auto; display: block; text-align: center;">Get me outta here!</a>';
echo'</div>';
die();
}
}
?>

我相信它是动作脚本中的UPDATE查询 - 我知道它不是那么安全但是我会整理它。
答案 0 :(得分：2)
正确设置execute的参数。这是一个数组，现在你有一些奇怪的东西：
$query->execute(array(":cat_title"=>$_POST["cat_title"],
":cat_color"=> $_POST["cat_color"]), // extra )
":cat_icon"=> $_POST["cat_icon"]), // extra )
":cat_id"=> $_POST["cat_id"]));
应该是：
$query->execute(array(
":cat_title"=>$_POST["cat_title"],
":cat_color"=> $_POST["cat_color"],
":cat_icon"=> $_POST["cat_icon"],
":cat_id"=> $_POST["cat_id"]
));
