看似没有发布到PHP的HTML表单 [英] HTML Form seemingly not posting to PHP

问题描述

您好，感谢您的宝贵时间。

无论研究的数量如何，我都找不到已经讨论过的解决方案。

问题是提交按钮自动重定向，看起来没有发布表单。它一直工作，直到我从MySQL函数转换为MySQLi。其他所有功能都在工作，但这部分网站。

$ b HTML表单（myaccount.inc.php）：

 < div id =change-password> 
 
< form class =clearfixaction =method =post> 
 
< div>< span class =he1>更改密码< / span>< / div> 
 
< div> 
<？php include_once'controllers / accountController.php'; ？> 
< / div> 
 
< div>< label class =fieldlabelfor =password>当前密码：< / label>< / div> 
< input type =passwordname =passwordid =passwordsize =23/>< br /> 
 
< div>< label class =fieldlabelfor =passwordnew1>新密码：< / label>< / div> 
< input type =passwordname =passwordnew1id =passwordnew1size =23/>< br /> 
 
< div>< label class =fieldlabelfor =passwordnew2>确认新密码：< / label>< / div> 
< input type =passwordname =passwordnew2id =passwordnew2size =23/>< br /> 
 
< input type =submitname =submitvalue =更改密码class =bt_changepass/> 
 
< / form> 
 
< / div> 
  

然后，这个表单由于没有更好的术语，被一些PHP控制。

$ b

PHP（accountController.php）：

  / /检查密码更改表单是否已提交。 
 if（isset（$ _ POST ['submit']）=='Change Password'）
 {
 echo< br />; 
 
 //从数据库中获取数据。 
 $ sql = $ mysqli-> query（SELECT * FROM ss_members WHERE usr ='。$ _ SESSION ['usr']。'AND pass ='.md5（$ _ POST ['password']] ） '）。 
 $ row = $ sql-> fetch_assoc（）; 
 
 //将持有我们的错误
 $ err = array（）; 
 
 if（$ _ POST ['password'] ==|| $ _POST ['passwordnew1'] ==|| $ _POST ['passwordnew2'] ==）
 {
 $ err [] ='所有字段必须填写！'; 
 
 $ b $ if（！$ row ['pass'] == md5（$ _ POST ['password']）&& $ _POST ['passwordnew1']！= && $ _POST ['passwordnew2']！=）
 {
 $ err [] ='当前密码不正确！ 
 
 $ b $ if if（$ _ POST ['passwordnew1']<> $ _POST ['passwordnew2']）
 {
 $ err [] ='New密码不匹配！'; 
 
 $ b $ if if（！count（$ err））
 {
 if（$ row ['usr']）
 {
 //如果一切正常，请更改密码。 
 $ stmt = $ mysqli-> prepare（UPDATE ss_members SET pass = md5（？）WHERE usr = {$ _SESSION ['usr']}）; 
 $ stmt-> bind_param（'s'，$ _POST ['passwordnew1']）; 
 $ stmt-> execute（）; 
 $ stmt-> close（）; 
 
 echo密码已经成功更新！< br />; 
} 
 else 
 {
 $ err [] ='有东西坏了！'; 
 
 
 $ b $ if（$ err）
 {
 //保存会话中的错误信息。 
 foreach（$ err as $ error）
 {
 echo $ error。 < br />; 
} 
} 
 
 echo< br />; 
 
  

解决方案

<？php include_once'controllers / accountController.php'; ？>

发送了标头之后。

移动

<？php include_once'controllers / accountController.php'; ？>

到页面顶部，在处理程序部分内，或者您可以将表单提交到

controllers / accountController.php

使用

< form class =clearfixaction =controllers / accountController.phpmethod =post>

Hello and thank you for your time.

Regardless of the amount of research I do, I cannot find an already-discussed solution to this problem.

The problem is that the submit button automatically redirects, seemingly without posting the form. It worked until I converted from MySQL functions to MySQLi. Everything else is working but this part of the website.

HTML form (myaccount.inc.php):

<div id="change-password">

<form class="clearfix" action="" method="post">

        <div><span class="he1">Change Password</span></div>

        <div>
            <?php include_once 'controllers/accountController.php'; ?>
        </div>

        <div><label class="fieldlabel" for="password">Current Password:</label></div>
        <input type="password" name="password" id="password" size="23" /><br />

        <div><label class="fieldlabel" for="passwordnew1">New Password:</label></div>
        <input type="password" name="passwordnew1" id="passwordnew1" size="23" /><br />

        <div><label class="fieldlabel" for="passwordnew2">Confirm New Password:</label></div>
        <input type="password" name="passwordnew2" id="passwordnew2" size="23" /><br />

        <input type="submit" name="submit" value="Change Password" class="bt_changepass" />

</form>

</div>

This form is then, for lack of a better term, controlled by some PHP.

PHP (accountController.php):

// Checking whether the Password Change form has been submitted.
if(isset($_POST['submit'])=='Change Password')
{
echo "<br />";

// Get the data from the database.
$sql = $mysqli->query("SELECT * FROM ss_members WHERE usr = '".$_SESSION['usr']."' AND pass = '".md5($_POST['password'])."'");
$row = $sql->fetch_assoc();

// Will hold our errors
$err = array();

if($_POST['password'] == "" || $_POST['passwordnew1'] == "" || $_POST['passwordnew2'] == "")
{
    $err[] = 'All the fields must be filled in!';
}

if(!$row['pass'] == md5($_POST['password']) && $_POST['passwordnew1'] != "" && $_POST['passwordnew2'] != "")
{
    $err[] = 'Current password is not correct!';
}

if($_POST['passwordnew1'] <> $_POST['passwordnew2'])
{
    $err[] = 'New passwords do not match!';
}

if(!count($err))
{
    if($row['usr'])
    {
        // If everything is OK change password.
        $stmt = $mysqli->prepare("UPDATE ss_members SET pass = md5(?) WHERE usr = {$_SESSION['usr']}");
        $stmt->bind_param('s', $_POST['passwordnew1']);
        $stmt->execute();
        $stmt->close();

        echo "Password has been sucessfully updated!<br />";
    }
    else
    {
        $err[]='Something broke!';
    }
}

if($err)
{
    // Save the error messages in the session.
    foreach($err as $error)
    {
        echo $error . "<br />";
    }   
}

echo "<br />";
}

解决方案

The problem is you are including the

<?php include_once 'controllers/accountController.php'; ?>

after the headers have been sent.

You can either move the

<?php include_once 'controllers/accountController.php'; ?>

to the top of the page, inside the handler part, or you can submit the form to

controllers/accountController.php

using

<form class="clearfix" action="controllers/accountController.php" method="post">
