cart codeigniter

Dude! Modularize your code! It's close to impossible to follow what is going on

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
