Insert A Database Field

For example, first you extract a category(include category code and category name) and stored in database already. The next step, you want extract the detail items of each categories, so, you need to insert the category code into the URL, looks something like this:

http://www.example.com/category_items_list.php?category_code=<FIELD:T1,F2/>

The program will loop every value of this field, and memorize whether a value is extracted already to avoid the repeated extract when you start extract next time. To reset the extraction flag, please see Reset Extract Flag.
