thanks for the advice. i am getting a grip on jquery and ajax at the moment.

the reason is i am interested in learning a bit of ajax, i followed a few tutorials and while it queries using a database, i wanted to know what the process is (and know whether) arrays can be queried too.

I want to be able to check whether values exist in the php array without having to click the submit button to do those checks using jquery/ajax. when users enter an abbreviation in the text field want to be able to show that the brand exists (either vw or tyta) or not (as they type in the input box) and show the results in the carnamestatus div. I was following a tutorial from youtube, however it queried against a mysql database. I was wondering if this is possible using php arrays instead of mysql? I would be grateful if you could pick any faults in the code. The jquery is in the head section. the rest of the code is as follows: <?php $car = array() $car["vw"] = array( "name" => "volkswagen"); $car["tyta"] = array( "name => "toyota"); ?> the html code is as follows: <label for="carname">Car Code:</label> <input type="text" onblur="checkcar()" value="" id="carname" /> <div id="carnamestatus"></div> the checkcar() function checkcar(){ var u = _("carname").value; if(u != ""){ _("carname").innerHTML = 'checking ...'; var B = new XMLHttpRequest(); B.open("POST","check.php",true); / B.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); B.onreadystatechange = function() { if(B.readyState==4 && B.status== 200) { _("carnamestatus").innerHTML = B.responseText; } } var v = "carnamecheck="+u; B.send(v); } } </script>
