Question

我尝试的是update我的数据库中使用Json数据的列。我开始解码数据，它显示了特定数据的价值，我只是坚持下一步应该做的事情。

登录代码

if(strtolower($_GET['action']) == "login")

{
    $username = $_POST['username'];
    $password = md5($_POST['password']);

    if (!$_POST['username'] | !$_POST['password'] ) 
    {
        die("<div style='text-indent: 10px;color: #FF0000;margin-top: -27px;'>Error - Please fill out the required fields to login</div>");
    }

    if($username == null)    return;

    if($password == null)    return;


    if(!$conn)    die("MySQL Error.");

    $result = $conn->prepare("SELECT * FROM `users` WHERE username= :Player AND password= :Pass");
    $result->bindParam(':Player', $username); 
    $result->bindParam(':Pass', $password);
    $result->execute(); 

    if(!$result)    die("An Error has occured");

    $rows = $result->fetch(PDO::FETCH_ASSOC);

    $c = unserialize($rows['addons']);
    $profileData = $rows['profile'];

    #gets json data from $profileData
    $json_a=json_decode($profileData,true);
    $json_o=json_decode($profileData);
    foreach($json_o->profile as $p)


    if(!$rows) die("<div style='text-indent: 10px;color: #FF0000;margin-top: -27px;'>Error - Username or Password was incorrect</div>");

    if($c['powers']['profile']['has'] == 0) die("<div style='text-indent: 10px;color: #FF0000;margin-top: -27px;'>Error - You don't have the available permission to edit your profile</div>");

    echo ("<div style='text-indent: 350px;position: absolute;  margin-top: 33px;'>Login as <b><a target='_blank' href='http://localhost/uprofile.php?u=$username'> $username </a></b></div>");
    ?>

这是我解码配置文件数据的地方

 $json_a=json_decode($profileData,true);
        $json_o=json_decode($profileData);
        foreach($json_o->profile as $p)

更新代码：

<?php
    }
    else
    if(strtolower($_GET['action']) == "publish")
    {
        $username = $_POST['myname'];
        $value = $_POST['value'];

        if(!$conn)        die("MySQL Error.");

        $q = $conn->prepare("UPDATE users SET profile = :Profile WHERE username= :Player ");
        $q->bindParam(':Player',$username);
        $q->bindParam(':Profile',$value);
        if($q->execute()){
                echo "<div style='text-indent: 10px;color: #008000;margin-top: -27px;'>Profile has been updated</div>";
            } else {
                echo "Couldn't update Profile";
            }

    }
    else
    {
        ?>

输出值$p->detail

如下所示

  <form action='?action=publish' method='post'>
    <textarea rows="30" cols="90" name="value" style="margin: 0px 0px 10px; width: 655px; height: 394px;">
    <?php echo $p->detail; ?>
    </textarea>
</form>
