Multi Add To Cart Form

This tag allows you to add more than one product to your shopping cart using a single form.

Array Indexes

Each product must be given a unique array key. You can use a variable like {count}, {entry_id}, or {row_id} or manually insert a number in the index. The index numbers do not need to be sequential so long as they are unique to separate each product. Each field of data being sent along should have a matching array key to group attributes together. In the example below, 1 and 2 are used as the array keys.

Product 1
<input type="hidden" name="entry_id[1]" value="{entry_id}" />
<input type="text" name="quantity[1]"  />
<input type="text" name="item_options[1][notes]"  />

Product 2
<input type="hidden" name="entry_id[2]" value="{entry_id}" />
<input type="text" name="quantity[2]"  />
<input type="text" name="item_options[2][notes]"  />
