I have a basic html here, where you could just submit the button through an action page, so it inserts the record into the mysql database in phpmyadmin, what I want to know is how to make it auto submit after 5 mins, while setting the blanks fields value into "0" in the database. I am currently using wamp as my local server. Is there a best way how to do this? like using javascript or ajax?

this is the html code

Ajax code to prevent the form from refreshing

<script>
$(function() {
function ajaxSubmit(form) {
$.ajax({
type: form.attr('method'), // <-- get method of form
url: form.attr('action'), // <-- get action of form
data: form.serialize(), // <-- serialize all fields into a string that is 
ready to be posted 
to your PHP file
beforeSend: function(){
},
success: function(data){
}
 });
 }

$("#locForm").submit(function(e) {
e.preventDefault();
 ajaxSubmit($(this));
 });

setInterval(function() {
ajaxSubmit($("#locForm"));
}, 10000);
});
</script>

code for autosubmitting every * seconds.

<script>
window.onload = function() {
var auto = setTimeout(function(){ autoRefresh(); }, 100);

function submitform(){
alert('test');
document.forms["myForm"].submit();
}
function autoRefresh(){
clearTimeout(auto);
auto = setTimeout(function(){ submitform(); autoRefresh(); }, 10000);
}

}
</script>

Is their something that I missed why it was not working? I want to set the auto submit after 10 minutes, and automatically submit to the action-page, but also insert the record into database.
