json_encode boolean returning wrong value

I'm writing a jquery login. If the php login script (checklogin.php) echoes "true" then my jquery page is supposed to give an alert. When I run a login.php (that doesn't use jquery) it sends the request to checklogin.php which echoes "true" however if I use my jquery login script to send the login info to checklogin.php, the alert I trace back says "false". ``` $('#login').click(function(e){ $.getJSON("http://www.hedonsoft.com/game/login.php",{username: $("#username").val(), password: $("#password").val()},function(data){ if(data==true){ alert(data.boolean); //$('#logindiv').slideUp(); //$('#gamediv').show(); //$('#registerdiv').hide(); //$('#gameheader').html(data['username']); }else{ alert("false"); } }); }); <?php header('Access-Control-Allow-Origin: *'); $host="localhost"; // Host name $username=""; // Mysql username $password=""; // Mysql password $db_name="hedonsof_conflict"; // Database name $tbl_name="members"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // username and password sent from form $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); $json = array('boolean' => 'true', 'jsonUser' => $myusername); echo "true"; } else { echo "Wrong Username or Password"; } ?> ``` So long story short, when I try to login from a regular php page the value I trace is true, when I try to login from a jquery page the value I trace is false; EDIT: ``` <?php ... $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); $json = array('boolean' => true, 'jsonUser' => $myusername); echo true; } else { echo "Wrong Username or Password"; } ?> ``` And my jQuery... ``` $('#login').click(function(e){ $.getJSON("http://www.hedonsoft.com/game/login.php",{username: $("#username").val(), password: $("#password").val()},function(data){ if(data){ alert("true"); //$('#logindiv').slideUp(); //$('#gamediv').show(); //$('#registerdiv').hide(); //$('#gameheader').html(data['username']); }else{ alert(data); // shows null } }); }); ``` With `json_encode`, boolean's value is returned `null` ``` $('#login').click(function(e){ $.getJSON("http://www.hedonsoft.com/game/login.php",{username: $("#username").val(), password: $("#password").val()},function(data){ if(data.boolean == "true"){ alert("true"); //$('#logindiv').slideUp(); //$('#gamediv').show(); //$('#registerdiv').hide(); //$('#gameheader').html(data['username']); }else{ alert(data); } }); }); ``` ``` <?php ... // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); $json = array('boolean' => true, 'jsonUser' => $myusername); echo json_encode($json); } ... ?> ```
