list of records

Manuel
How could I make a form to update a list of records with checkbox using the class formGeneration?

Have you checked the form_list_select plugin? Take a look at the test_list_select.php example script.

In this case is a list of radio to select a record. But I need to list the records and put a ckeck box in each, to select the records that I want to update in the db.
Like a list of emails in your inbox where you select all of you want to delete.
It has to do with the same (class) example?

Just use the MULTIPLE attribute and radio buttons become checkboxes so you the user can select more then one of the options. It is compatible with the regular select inputs but with several enhancements. Check the documentation.

Sorry.
Documentation is ok. My mistake.
It works perfectly.
Thank you very much.
