Question

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();
    }
}

?>

    <form action="actions/update_cat.php" method="POST" id="rtf" name="">

        <input type="hidden" value="<?php echo $cat['cat_id'] ?>" name="cat_id" />
        <input type="text" value="<?php echo $cat['cat_title'] ?>" name="cat_title" /><br><br>

        <input onclick="formsubmit()" type="submit" value="Update Category" name="submit"/>


    </form>

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。

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"]
));

表不更新
