 if (isset($_POST['submitBtn'])){

 

 

Thanks in advance

Very difficult to help when all we are getting is a couple pieces of some supposed code. How about showing us the full lines involved? Not the whole script, but the parts you are mentioning.

 <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" name="loginform">
        <table width="100%">
          <tr><td>Username:</td><td> <input class="text" name="username" type="text"  /></td></tr>
          <tr><td>Password:</td><td> <input class="text" name="password" type="password" /></td></tr>
          <tr><td colspan="2" align="center"> <input name="submit" type="submit" value="Submit" /> </td></tr>
        </table> 
      </form>

 

if (isset($_POST['submit'])){
 // Get user input
 $username = isset($_POST['username']) ? $_POST['username'] : '';
 $password = isset($_POST['password']) ? $_POST['password'] : '';
       
 // Try to login the user
 $error = loginUser($username,$password);
}
 

 

function loginUser($user,$pass){
 $errorText = '';
 $validUser = false;
 
 // Check user existance 
 $pfile = fopen("userpwd.txt","r");
    rewind($pfile);

    while (!feof($pfile)) {
        $line = fgets($pfile);
        $tmp = explode(':', $line);
        if ($tmp[0] == $user) {
            // User exists, check password
            if (trim($tmp[2]) == trim(md5($pass))){
             $validUser= true;
             $_SESSION['userName'] = $user;
            }
            break;
        }
    }
    fclose($pfile);

    if ($validUser != true) $errorText = "Invalid username or password!";
   
    if ($validUser == true) $_SESSION['validUser'] = true;
    else $_SESSION['validUser'] = false;
 
 return $errorText; 
}

for some reason instead of parsing the php it's convert the < to %3C    Need to see what's at the top of the page.

 <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post" name="loginform">
        <table width="100%">
          <tr><td>Username:</td><td> <input class="text" name="username" type="text"  /></td></tr>
          <tr><td>Password:</td><td> <input class="text" name="password" type="password" /></td></tr>
          <tr><td colspan="2" align="center"> <input name="submit" type="submit" value="Submit" /> </td></tr>
        </table> 
      </form>

 

if (isset($_POST['submit'])){
 // Get user input
 $username = isset($_POST['username']) ? $_POST['username'] : '';
 $password = isset($_POST['password']) ? $_POST['password'] : '';
       
 // Try to login the user
 $error = loginUser($username,$password);
}
 

 

function loginUser($user,$pass){
 $errorText = '';
 $validUser = false;
 
 // Check user existance 
 $pfile = fopen("userpwd.txt","r");
    rewind($pfile);

    while (!feof($pfile)) {
        $line = fgets($pfile);
        $tmp = explode(':', $line);
        if ($tmp[0] == $user) {
            // User exists, check password
            if (trim($tmp[2]) == trim(md5($pass))){
             $validUser= true;
             $_SESSION['userName'] = $user;
            }
            break;
        }
    }
    fclose($pfile);

    if ($validUser != true) $errorText = "Invalid username or password!";
   
    if ($validUser == true) $_SESSION['validUser'] = true;
    else $_SESSION['validUser'] = false;
 
 return $errorText; 
}

What is the name of this file?

 

Also - you are wondering about your JS, yet you aren't showing us any JS code. Where does the JS code come into play here?

[priya117]

the name of this file is login.php, and the js is coming from other page(common.php) where it calls the function loginUser 

 

<?php
require_once('common.php');

$error = '0';

if (isset($_POST['submitBtn'])){
 // Get user input
 $username = isset($_POST['username']) ? $_POST['username'] : '';
 $password = isset($_POST['password']) ? $_POST['password'] : '';
       
 // Try to login the user
 $error = loginUser($username,$password);
}
?>

Am I hearing that you want to call a JS function from PHP?

[priya117]

yes on click of submit

[ginerjm]

Can we see that code?  I'm still confused since you seem to be saying now that the js is being called from an html submit and NOT PHP.
