HTML表格似乎沒有發佈到PHP

Question

你好，感謝你的時間。

無論研究的數量如何，我都找不到已經討論過的解決方案。

問題是，提交按鈕自動重定向，看似沒有張貼表單。它一直工作，直到我從MySQL函數轉換爲MySQLi。其他一切正在工作，但這部分的網站。

HTML表單（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> 

這種形式的話，由於缺乏一個更好的詞，被一些PHP控制。

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 />"; 
} 

Answer 1

問題是要包括的

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

標題發送後。

您可以移動

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

到頁面的頂部，處理器部分的內部，也可以使用表單提交給

controllers/accountController.php

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

Answer 2

。在你的<form>標籤沒有action集，它是將數據發送到同一個文件。即，myaccount.inc.php。

將其更改爲：

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

Answer 3

試試這個：

給表單動作accountController.php

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

Answer 4

將您的action更改爲此，因爲accountController.php存在於controllers文件夾內。

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

Answer 5

mysqli的一類，而它的功能查詢不是靜態的，所以在那裏，你必須聲明的mysqli類的實例可以使用$mysqli->query之前。

你應該把

$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'my_db');

前

$sql = $mysqli->query("SELECT * FROM ss_members WHERE usr = '".$_SESSION['usr']."' AND pass = '".md5($_POST['password'])."'");
