PHP LOGIN脚本在Xampp本地主机上工作，但在Cpanel上不工作

Question

I'm making a simple login script in PHP. Its working fine on my XAMPP localhost but I can not run it on CPANEL. The scarier part is it does not give me any error instead the login form page reload every time I submit.

THE FORM:

<div class="panel-body">
    <form role="form" method="post" action="<?php $_PHP_SELF ?>">
      <div class="form-group">
        <div class="input-group"> <span class="input-group-addon"><span class="glyphicon glyphicon-user"></span></span>
          <input type="text" class="form-control" id="exampleInputEmail1" name="name" placeholder="Admin ID" required>
        </div>
      </div>
      <div class="form-group">
        <div class="input-group"> <span class="input-group-addon"><span class="glyphicon glyphicon-star"></span></span>
          <input type="password" class="form-control" id="exampleInputPassword" name="password" placeholder="Password" required>
        </div>
      </div>
       <hr/>
   <!--   <button type="button" class="btn btn-success"><span class="glyphicon glyphicon-arrow-left"></span> Back</button>-->
      <button type="submit" class="btn btn-warning" name="admin_login"><span class="glyphicon glyphicon-log-in"></span> Sign In</button>
      <p><br/>
      </p>

THE SCRIPT on the same php file:

<?php
include "sessionforadmin.php";
include "connection.php";

if(isset($_POST["admin_login"])){

if(!empty($_POST['name']) && !empty($_POST['password'])) {
    $user=$_POST['name'];
    $pass=$_POST['password'];

    $user = mysql_real_escape_string($user);
    $pass= md5( mysql_real_escape_string($pass));

    $query=mysql_query("SELECT * FROM admin WHERE admin_name='".$user."' AND password='".$pass."'");
    $numrows=mysql_num_rows($query);

    if($numrows!=0)
    {
    while($row=mysql_fetch_assoc($query))
    {
    $dbusername=$row['admin_name'];
    $dbpassword=$row['password'];
    }

    if($user == $dbusername && $pass == $dbpassword)
    {

    user_login( $user );

    /* Redirect browser */
    header("Location: home.php");
    }
    } else {
    ?>
    <script>
        alert("Invalid username or password!");
        document.location.href='index.php';
        </script>
        <?php 
    }

} else { ?>
    <script>
        alert("All Field are required!");
        document.location.href='index.php';
        </script>
        <?php 
}
}

?>

EDIT :

The Error that I receive on doing error_reporting is:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/exploitb/public_html/badminpanel/index.php:29) in /home/exploitb/public_html/badminpanel/sessionforadmin.php on line 2 Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/exploitb/public_html/badminpanel/index.php:29) in /home/exploitb/public_html/badminpanel/sessionforadmin.php on line 2 Warning: mysqli_select_db() expects exactly 2 parameters, 1 given in /home/exploitb/public_html/badminpanel/connection.php on line 8

Where am I wrong here??

Answer 1

by default in the cpanel(online host) might disable error reporting, put error_reporting(E_ALL); beginning of the php code then you might can see where you wrong

Answer 2

Instead of using mysql_query(), use mysqli_query();

Syntax: mysqli_query(your_connection_variable, sql_query);
