HI have created a shopping cart through a number of examples using php and ajax.

This cart allows me to drag an item into the cart and then the cart updates displaying that items class name.

I have never done any php before so am having trouble adding to this.

I want to add to the script an if statement that would say for example

if(id="item1")

{

price=20

}

else

if{(id="item2")

{

price=15

}

etc etc

I hope you can understand what i mean.

Would be extremely gratefull if someone could help me with how to write this within my script.
