dear albertleao

here is the main code for increase and decrease the quantity, but its not working..

function minquantity(rowid){
var minquan = parseInt($('#txtquantity_' + rowid).val()) - 1;
if(minquan > 0) {
//alert(quan);
$.ajax({
type: "POST",
url: "<?php echo base_url();?>ajax",
data: { action: "product_model.update_cart", row_id: rowid, new_qty: minquan}
}).done(function( msg ) {
var total = parseInt(msg);
if(total > 0){
$('#cart_count').html(total);
$('#txtquantity_'+rowid).val(minquan);
}
});

}
}

function plusquantity(rowid){
var plusquan = parseInt($('#txtquantity_' + rowid).val()) + 1;
//alert(quan);
$.ajax({
type: "POST",
url: "<?php echo base_url();?>ajax",
data: { action: "product_model.update_cart", row_id: rowid, new_qty: plusquan}
}).done(function( msg ) {
var total = parseInt(msg);
if(total > 0){
$('#cart_count').html(total);
$('#txtquantity_' + rowid).val(plusquan);
}
});
}

dude you have to paste as a code block not just a simple text. Is almost impossible to detect the PHP in all that.
I do Front-End development most of the time

His methods are not going to update anything he posting to the base_url() and no method
to change the values.
What did you Try? What did you Get? What did you Expect?
