It appears that there should be another program that has a form and does a POST to this program. This program is processing the POST information that was sent to it.

This obviously is meant to work with form data or an ajax script sent via js (post method). The first bit (referer), I think is there to stop users accessing the script directly - it must be called via a form (or ajax).

var totalprice=0;

$(document).ready(function(){
	
	$('.product').simpletip({
		
		offset:[40,0],
		content:'<img src="img/ajax_load.gif" alt="loading" style="margin:10px;" />',
		onShow: function(){
			
			var param = this.getParent().find('img').attr('src');
			
			if($.browser.msie && $.browser.version=='6.0')
			{
				param = this.getParent().find('img').attr('style').match(/src=\"([^\"]+)\"/);
				param = param[1];
			}
			
			this.load('ajax/tips.php',{img:param}); 
		} 

	});
	
	$(".product img").draggable({
	
	containment: 'document',
	opacity: 0.6,
	revert: 'invalid',
	helper: 'clone',
	zIndex: 100
	
	});

	$("div.content.drop-here").droppable({
	
			drop:
					function(e, ui)
					{
						var param = $(ui.draggable).attr('src');
						
						if($.browser.msie && $.browser.version=='6.0')
						{
							param = $(ui.draggable).attr('style').match(/src=\"([^\"]+)\"/);
							param = param[1];
						}

						addlist(param);
					}
	
	});

});


function addlist(param)
{
	$.ajax({
	type: "POST",
	url: "ajax/addtocart.php",
	data: 'img='+encodeURIComponent(param),
	dataType: 'json',
	beforeSend: function(x){$('#ajax-loader').css('visibility','visible');},
	success: function(msg){
		
		$('#ajax-loader').css('visibility','hidden');
		if(parseInt(msg.status)!=1)
		{
			return false;
		}
		else
		{
			var check=false;
			var cnt = false;
			
			for(var i=0; i<purchased.length;i++)
			{
				if(purchased[i].id==msg.id)
				{
					check=true;
					cnt=purchased[i].cnt;
					
					break;
				}
			}
			
			if(!cnt)
				$('#item-list').append(msg.txt);
				
			if(!check)
			{
				purchased.push({id:msg.id,cnt:1,price:msg.price});
			}
			else
			{
				if(cnt>=3) return false;
				
				purchased[i].cnt++;
				$('#'+msg.id+'_cnt').val(purchased[i].cnt);
			}
			
			totalprice+=msg.price;
			update_total();

		}
		
		$('.tooltip').hide();
	
	}
	});
}

function findpos(id)
{
	for(var i=0; i<purchased.length;i++)
	{
		if(purchased[i].id==id)
			return i;
	}
	
	return false;
}

function remove(id)
{
	var i=findpos(id);

	totalprice-=purchased[i].price*purchased[i].cnt;
	purchased[i].cnt = 0;

	$('#table_'+id).remove();
	update_total();
}

function change(id)
{
	var i=findpos(id);
	
	totalprice+=(parseInt($('#'+id+'_cnt').val())-purchased[i].cnt)*purchased[i].price;
	
	purchased[i].cnt=parseInt($('#'+id+'_cnt').val());
	update_total();
}

function update_total()
{
	if(totalprice)
	{
		$('#total').html('total: $'+totalprice);
		$('a.button').css('display','block');
	}
	else
	{
		$('#total').html('');
		$('a.button').hide();
	}
}

No, your form page is missing.

What is the purpose of what you are doing ? Send data without form or POST method ? You need HTML form in which data passed by this form and send to the specific CGI and process that data, otherwise use the GET method that passes via URL.
