Jqueryajax And Php Logic

Hey guys im with a problem getting a value from php. I know we have a lot of problems with this kind of issues, but i need help. This is my javascript $( document ).ready(function(

Solution 1:

Everything else is fine, you are not passing data correctly to ajax call. You are making query string but you have to pass JSON object if you want to capture it in $_POST in php and can append to url if you want to capture in $_GET array. I have corrected your function in both ways below:

functionvalidate_user() {

    //We get data inputvar username = $('.username').val();
    var password = $('.password').val();

    //We create a datastring ex: functions.php?function=validate_user&username=username&password=passwordvar datastring = { 'function': 'validate_user', 'username': username, 'password': password }

    //The json Ajax Request
    $.ajax({
        type: 'POST',
        dataType: 'json',
        url: '@loginAPI/functions.php',
        data: datastring,
        success: function(result) {
            console.log(result);
            $(".loading_bg").fadeOut("slow");
        },
        error: function(xhr, status){
            console.log(status);
        }

    });
    returnfalse;

}

When you want to capture data in $_GET at server side

functionvalidate_user() {
    //We get data inputvar username = $('.username').val();
    var password = $('.password').val();

    //We create a datastring ex: functions.php?function=validate_user&username=username&password=passwordvar datastring = 'function=validate_user' + '&username=' + username + '&password=' + password; 

    //The json Ajax Request
    $.ajax({
        type: 'POST',
        dataType: 'json',
        url: '@loginAPI/functions.php?' + datastring,
        data: {},
        success: function(result) {
            console.log(result);
            $(".loading_bg").fadeOut("slow");
        },
        error: function(xhr, status){
            console.log(status);
        }

    });
    returnfalse;

}

Here is PHP Code

<?phprequire_once('../@configs/db_connect.php');
//Lets send our data back to indexif(isset($_GET['function'])) {
    $user = $_GET['username'];
    $password = $_GET['password'];
    echo login::validate_user($user, $password);   
}
.... // Remaining Class will come here
