Ok it is alerting error2. After it alerts error2 it alerts bla22... self recursion? wtf? Also it shouldn't even get to error2 considering fInp.length is 4 and valu.length is 6 O_o

 

	function update(fInp, valu) {
	alert('bla1');
	var ord = document.getElementById('ctrordernumber').value;
	alert('bla2');
	alert (fInp.length);
	alert (valu.length);
	if(fInp.length != 0 && valu.length != 0){
		$.post("updateorder-exec.php", {field: ""+fInp+"", val: ""+valu+"", on: ""+ord+""}, function(data){
			alert('bla22');
			if(data.length >0) {
				alert('bla3');
				if(data) {
					//$('#errDiv').show();
					//$('#errDiv').html("Database updated!");
					alert('updated');
					//$('#errDiv').css('opacity',100).fadeOut(10000);
				} else{
					alert('error');
					//$('#errDiv').show();
					//$('#errDiv').html("Error. Incorrect information entered!");
					//$('#errDiv').css('opacity',100).fadeOut(10000);
				}
				return data;
			}
		});
	}
	alert('error2');
	//$('#errDiv').show();
	//$('#errDiv').html("Error. Incorrect information entered!");
	//$('#errDiv').css('opacity',100).fadeOut(10000);

	return 0;
}
