通过HTML表单访问PHP文件
[英]Accessing PHP file through HTML form
问题描述
I am working on my website which having different tabs (home, contact, etc.). 
我正在网站上使用不同的选项卡（“主页”，“联系人”等）。 Now in one of these tabs I'm using a login form, in this form I'm just validating one fixed user ( Not Using database ), this will understand from verification.php code. 现在在这些选项卡之一中，我正在使用登录表单，在此表单中，我仅在验证一个固定用户（“ 不使用数据库” ），这可以从verification.php代码中了解。
Below is part of .html file code that calling verification.php file 以下是调用verification.php文件的.html文件代码的一部分
<div id="loginn" class="loginForm">
<form action="verfication.php" method="post">
<div class="ll">
<img src="image/avatar2.png">
</div>
<label for="name"><b>Username</b></label><br>
<input type="text" name="uname" required><br>
<label for="psw"><b>Password</b></label><br>
<input type="password" name="psw" required><br>
<button type="submit">Login</button>
</form>
</div>
Below is my verification.php file, which is saved by me in www directory, where all the html, css, js files are stored 以下是我的verification.php文件，该文件由我保存在www目录中，其中存储了所有html，css，js文件
<!DOCTTYPE html>
<html>
<body>
<?php
if(isset($_POST['uname']) and isset($_POST['psw']))
{
$name=$_POST['uname'];
$pass=$_POST['psw'];
if ( $name == "rrrr" and $pass="ravina@6543" )
{
?>
<script type="text/javascript">document.getElementById('veri').style.display="block";</script>
<script type="text/javascript">document.getElementById('loginn').style.display="none";</script>
<?php}
}
?>
</body>
</html>
Now the problem is, when I click on the login button, there is nothing happening on the html part. 现在的问题是，当我单击登录按钮时，html部分上没有任何反应。 I mean, my PHP file is not getting access from my HTML part, so please can anyone help me to solve these problem? 我的意思是，我的PHP文件无法从我的HTML部分获得访问权限，所以请有人可以帮助我解决这些问题吗？

I think there's an error in the syntax: first of all there is an additional "T" in the <!DOCTTYPE html> and secondly there's a curly bracket after you started the php script: <?php} , just adding a space will fix your problem. 我认为语法有错误：首先， <!DOCTTYPE html>有一个附加的“ T”，其次，在启动php脚本后出现了花括号： <?php} ，只需添加一个空格即可解决你的问题。
There's also a spelling mistake in your html code regarding the name of the php file verification.php . 您的html代码中还存在有关php文件verification.php名称的拼写错误。
<!DOCTYPE html> <html> <body> <?php if(isset($_POST['uname']) and isset($_POST['psw'])) { $name=$_POST['uname']; $pass=$_POST['psw']; if ( $name == "rrrr" and $pass="ravina@6543" ) { ?> <script type="text/javascript">document.getElementById('veri').style.display="block";</script> <script type="text/javascript">document.getElementById('loginn').style.display="none";</script> <?php } } ?> </body> </html>

in your verification.php, you can check success/not with using only echo 在您的Verification.php中，您可以仅使用echo来检查成功/不成功
<!DOCTYPE html>
<html>
<body>
<?php
if(isset($_POST['uname']) and isset($_POST['psw']))
{
$name=$_POST['uname'];
$pass=$_POST['psw'];
if ( $name == "rrrr" and $pass="ravina@6543" )
{
echo "success~~";
} else {
echo "failed!!";
}
}
?>
</body>
</html>

This is not how to use PHP, HTML and javascript. 这不是使用PHP，HTML和javascript的方法。 You should start by learning how HTTP works, then HTML, then JavaScript and finally PHP. 您应该首先学习HTTP的工作方式，然后是HTML，然后是JavaScript，最后是PHP。

首先，您应该以html格式正确地编写php文件的名称，即Verification.php Verification.php文件从DOCTTYPE html中删除一个T，并在php和{在PHP {中插入这行之间。
