Noob question

I am trying to create a way to buy units on my game, i have created an array to bring the units info from the database and displayed it in a table.

 

My problem is when it comes to actually buying some units. I have a text box appearing next to each unit which will be used by a player to enter the amount of each unit they wish to buy.

 

How would i define the text boxes to each unit in the array so that when they hit BUY the right amount of each unit is purchased.

 

 

Thanks in Advance, Monk3h.

<input type="text" name="buy[1]" value="0" />
<input type="text" name="buy[2]" value="0" />
<input type="text" name="buy[3]" value="0" />
<input type="text" name="buy[4]" value="0" />

 

where 1,2,3,4 are the IDs for each item. when that is posted, you can loop over the values like:

foreach($_POST['buy'] as $id=>$num){
  if(!is_numeric($num) || $num < 1) continue;
  echo "You want $num of $id";
}
