Help about Html Editor and Php method

Hello,

i need some help once more time.

I need to set up programmatically the content (in html) of an html editor that i have on my form. How is this possible? I tried the {id_sc_field_myfieldname} with no luck!

Also, i am wondering how can i remove the “ok” button that appears when i call a php method.

Thanks in advance

Theo
