How to fill a text box ( or two or three ) with the information from a dropbox?

Hello Bob

I can populate a dropbox with information from other dropbox. But how to fill a text box ( or two or three ) with the information from a dropbox?
I have a dropbox connected to a DB Multi Record Loader event to list data. Now I need to, after selecting the data that dropbox, fiil a textbox ( or two or three text box), with data filtered by a DB Record Loader .

On load I have a Dynamic Dropdown ( but I think to fill a textbox does not need, am I right? )

On ajax load have DB Record Loader ( with code to FIND the record according to selection dropbox ) . And I have the following code in custom code

< ? php
$ results = array ( ) ;
$ results [ ] = '= Select Tier ' ;
$ selected = " selected = 'selected ' " ;

foreach ( $ form - > data [' escalao_source_ajax '] as $ v ) {
$ results [ ] = $ v [' escalao_epocas '] '=' $ v [' escalao_epocas .'] . ;
}
$ results = implode ( " \ n" , $ results ) ;
echo $ results ;

$ mainframe = & JFactory :: getApplication ( ) ;
$ mainframe - > close ( ) ;
?>

1 - What do I need to change this code to populate a textbox ( two or three ) ?
2 - I have in mind that just need a registration , is straightforward to use use the DB Record Loader instead of DB Multi Record Loader?


Thanks

Hello AntonioGraca,
I'm not a Chrono professional, but after checking your new post, I think that the following links may help:
How can I show/hide a textarea when a checkbox is clicked?
P.S: I'm just an automated service😉

Sorry, calculus00
but, in this time, you did not help. I'll wait for a more "powerful" help. But

Thanks calculus00

Hi Bob
Another solution was to add a button, with a custom code, for populate these fields (textBox). How can I add a second Button and associate it with a 2nd event? (On Submit2, for example).

Thanks

HI Antonio,
For your second question just put a name in ID field of Submit button and add a OnClick event in your code...When press the button Submit will trigger a event.
