I want the price per unit to decrease when quantity is increased. I am using products (drop-down) and quantity (drop-down) fields. I have a very simple php if-else condition for this but i am dont know how to integrate this with the form. I have read about using hooks but i failed to use them. Please help me with this. Here is the php statement<br /> <pre><code>function get_price(baseprice, quantity){ if(quantity ==1) { total_price = baseprice*quantity; } else if(quantity&gt;1 &amp;&amp; quantity &lt;=10) { total_price = (baseprice-(baseprice*5/100))*quantity; } else if(quantity&gt;10 &amp;&amp; quantity &lt;=20) { total_price = (baseprice-(baseprice*10/100))*quantity; } else if(quantity&gt;20 &amp;&amp; quantity &lt;=50) { total_price = (baseprice-(baseprice*15/100))*quantity; } else if(quantity&gt;51 &amp;&amp; quantity &lt;=100) { total_price = (baseprice-(baseprice*20/100))*quantity; } else if(quantity&gt;=101) { total_price = (baseprice-(baseprice*25/100))*quantity; } return total_price; }</code></pre> <p>Can you please tell me how to use this with a hook and where to place the code.<br /> Thanks. </p>
