Question

在下面的代码中，除了单击提交按钮时，一切都有效，

请告诉我什么是错的，连接和一切都很好（它包含在Header.php文件中）并在其他页面上提交表单工作，但是这个似乎什么都不做，页面甚至没有加载< / p>

谢谢！

这是代码

<?php

//connection is in header
include "../Header.php";
//checks if logged in
if (!$User)
{
header("Location: ../index.php"); exit();
}
//heres the form
echo"<form><center><br /><br /><br /><br /><font size='3'><br />You are changing your Post Color<br />
Your current color is $myU->PostColor<br /><br /></font><form>
Color:<br /><textarea name='color' rows='1' cols='15'></textarea><br /><br />
<input type='submit' name='Submit' value='submit'></form></center></form>";

$Color = mysql_real_escape_string(strip_tags($_POST['Color']));
$submit = mysql_real_escape_string(strip_tags($_POST['submit']));



if ($submit) {

mysqli_query("UPDATE `socialli_main`.`Users` SET `PostColor` = '$Color' WHERE `Users`.`ID` ='$myU->ID'");

header("Location: ../index.php"); exit();
}



include "../Footer.php";

Answer 1

提交按钮将提交其中的表单。你根本没有<form>元素。你需要添加一个。

Answer 2

更重要的是，添加<form>标签实际上是在其上设置属性。请尝试以下方法。

<form action='' method='POST'>

您还多次结束</form>代码......

以下是我修改代码的方法：

<?php
    //connection is in header
    include "../Header.php";

    //checks if logged in
    if (!$User)
        header("Location: ../index.php"); exit();
?>
<form action='' method='POST'>
    <div style="text-align:center;">
        <br /><br /><br /><br /><br />
        <span style="font-size:1.6em;">
            You are changing your Post Color
        </span><br>
        <span style="font-size:1.3em;">
            Your current color is <?=$myU->PostColor?>
        </span><br>
        Color:<br />
            <textarea name='color' rows='1' cols='15'></textarea>
        <br /><br />
        <input type='submit' name='Submit' value='submit'>
    </div>
</form>
<?php
    $Color = mysql_real_escape_string(strip_tags($_POST['Color']));
    $submit = mysql_real_escape_string(strip_tags($_POST['submit']));

    if ($submit){
        mysqli_query("UPDATE `socialli_main`.`Users` SET `PostColor` = '$Color' WHERE `Users`.`ID` ='$myU->ID'");
        header("Location: ../index.php"); exit();
    }
include "../Footer.php";
?>

为什么此提交表单不起作用？
