TYPO3 features a shopping basket for the session-data.
When you submit data from forms (or by querystring) (post/get-method) in the array "recs" it's stored in the session-data under the key recs.
The syntax is like this:
recs[table_name][uid_of_record]
This form-element will change the registered value of record with uid=345 from the "tt_products" table in typo3. Please note, that the record itself is NOT in any way modified, only the "counter" in the session-data indicating the "number of items" from the table is modified.
<input name="recs[tt_products][345]">
NOTE on checkboxes:
When you are creating forms with checkboxes, the value of the checkbox is sent by MSIE/Netscape ONLY if the checkbox is checked! If you want a value sent in case of a disabled checkbox, include a hidden formfield of the same name just before the checkbox!
<INPUT type="hidden" name="recs[tt_content][345]" value="0">
<INPUT type="checkbox" name="recs[tt_content][345]" value="1">
