calling a php function from a button

pal_52

I have a button on the main form that passes a date and number to another form.

The second form when called loads the data from the database using the date and number supplied, load the data (from the database) displays it and allows the user to edit data. When the user is finished they press the "Save" button.

The save function is implemented in PHP so how do I call the PHP function to do the save? If I reload the form my unedited data will be reloaded (I would have thought).

Thanks for any help.

Why not make the "Save" button a submit button that submits the form to your PHP script?

Thanks for the comment.

I think that I will have to create an intermediate page that does nothing except receive data from other pages via submit buttons. The script in this page can determine who has called it and act according using PHP.

I guess that the real answer is Ajax but one step at a time.

Thanks

At the top of your second form, you could check if it came form itself or the previous form. If previous form populate data from a query, if its from itself populate the data from a $POST array, all data in a form will be sent, whether it was edited or not. IE if I only change one field, all the other fields will still be sent in $POST data.
You could then input that same post data in an update statement to save it to the database.

I had wondered about checking at the top of the form.

I have tried to submitting to another form and providing data to allow that form to determine what is to be done. It works fine and it could be used for all pages using a big case statement to call the appropriate functions.

Thanks for the help.
