Hello,

I am having a problem with this code I am using.

<?php
    //Start session
    session_start();
    
    //Include database connection details
    require_once('config.php');

    //Validation error flag
    $errflag = false;
    
    //Connect to mysql server
    $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
    if(!$link) {
        die('Failed to connect to server: ' . mysql_error());
    }
    
    //Select database
    $db = mysql_select_db(DB_DATABASE);
    if(!$db) {
        die("Unable to select database");
    }
    
    //Function to sanitize values received from the form. Prevents SQL injection
    function clean($str) {
        $str = @trim($str);
        if(get_magic_quotes_gpc()) {
            $str = stripslashes($str);
        }
        return mysql_real_escape_string($str);

Error

Parse error: parse error, expecting `T_STRING' or `T_VARIABLE' or `T_NUM_STRING' in C:\xampp\htdocs\server status\register-auth2.php on line 67

 

Please look through it, and see if you see anything wrong.

Change:

$qry = "SELECT * FROM users WHERE username='$_POST['username']'";

 

To:

$qry = "SELECT * FROM users WHERE username='".$_POST['username']."'";

 

Take care with double/single quotes. With your original code, PHP would have seen $_POST[ and then been cut off by the single quote.

I got it, I'm using a different code now. Started fresh.
