I've created this form with a jQuery autocomplete function. The selected brand from the autocomplete list needs to get sent to a PHP file using $.ajax function. My code doesn't seem to work but i can't find the error. I don't know why the data isn't getting inserted into MYSQL database. Here is my code:

JQUERY:

           $(document).ready(function() {

    $("#autocomplete").autocomplete({
        minLength: 2
    });

    $("#autocomplete").autocomplete({

        source: ["Adidas", "Airforce", "Alpha Industries", "Asics", "Bikkemberg", "Birkenstock", "Bjorn Borg", "Brunotti", "Calvin Klein", "Cars Jeans", "Chanel", "Chasin", "Diesel", "Dior", "DKNY", "Dolce &  Gabbana"]

    });

    $("#add-brand").click(function() {

        var merk = $("#autocomplete").val();

        $("#selected-brands").append(" <a class=\"deletemerk\" href=\"#\">" + merk + "</a>");

                //Add your parameters here        
                var param = JSON.stringify({
                    Brand: merk
                });

                $.ajax({
                    type: "POST",
                    async: true,
                    url: "scripttohandlejson.php",
                    contentType: "application/json",
                    data: param,
                    dataType: "json",
                    success: function (good){
                       //handle success

                       alert(good)
                    },
                    failure: function (bad){
                       //handle any errors

                       alert(bad)

                    }
                });


        return false;

    });

});

PHP FILE: scripttohandlejson.php

  <?PHP

     $getcontent = json_decode($json, true);

     $getcontent->{'Brand'};

     $vraag ="INSERT INTO kijken (merk) VALUES ='$getcontent' ";

     $voerin = mysql_query($vraag) or die("couldnt put into db");
