phpDBform is a library to help create a form linked or not to a MySQL or PostgreSQL database, to edit, insert, update and delete data, providing a nice presentation to the user. You start with pre-constructed files, and with little changes you have a working tool! But the main goal of this library, is the easy creating of forms, you need to instance a php class (dbform), choose the right parameters to the constructor, and use its methods to develop the interface, adding textboxes (add_textbox), checkboxes (add_checkbox), textareas (add_textarea) and the listboxes (add_listbox) that are linked with other tables to show the values that may go on the field (relational).
