Need help on Insert data to phpMyAdmin mySQL database

Discussion in 'PHP' started by aoiregion, Jul 18, 2014.

  1. #1
    Hi guys, I would like to seek help on inserting data whenever the switch is on or off to my sensor mySQL database in phpMyAdmin from my control.php. I'm using Raspberry PI as my hardware and follow a few tutorials to create my own Web Control Interface, it works perfectly without insert method. After I implemented insert method to my control.php and execute it, it cannot works and cannot store.

    This is my control.php:
    
    <?php
    session_start();
    
    $MySQLUsername = "MySQLUsername";
    $MYSQLUsersensor = "MYSQLUsersensor";
    $MySQLPassword = "MySQLPassword";
    
    
    $MySQLHost = "localhost";
    $MySQLDB = "gpio";
    $MYSQLDBsensor = "sensor";
    
    If (($MySQLUsername == "USERNAME HERE") || ($MySQLPassword == "PASSWORD HERE")){
        print 'ERROR - Please set up the script first';
        exit();
    }
    
    $dbConnection = mysql_connect($MySQLHost, $MySQLUsername, $MySQLPassword);
    mysql_select_db($MySQLDB, $dbConnection);
    If (isset($_POST['action'])){
        If ($_POST['action'] == "setPassword"){
            $password1 = $_POST['password1'];
            $password2 = $_POST['password2'];
            If ($password1 != $password2){
                header('Location: control.php');
            }
            $password = mysql_real_escape_string($_POST['password1']);
            If (strlen($password) > 28){
                mysql_close();
                header('location: control.php');
            }

    First off, you should look into not using mysql_ - use mysqli_ or PDO to connect to the database, and prepared queries - first off, they're a lot safer, and the amount of code needed is quite a bit less.
    Second, you should provide proper error-messages instead of just reloading files and such. For a login-script, the better is to just have the processing and the form in the same file, displaying error-messages if there's an error during login (wrong password, or similar).

    This is my latest edited code where I found out that I set my POST in GET and I have amended it already but the problem is still there.

    $MYSQLUsersensor = "MYSQLUsersensor";
    $MySQLPassword = "MySQLPassword";
