get date in thunderbird message via Dolphin send-to

Question

I have successfully created a working desktop file that send (one or more) attachments to thunderbird, with from, to fields and with, as a body, a file html. This is the file content:

[Desktop Entry]
Type=Service
Actions=SendToMailRcp
Encoding=UTF-8
MimeType=application/octet-stream
X-KDE-ServiceTypes=KonqPopupMenu/Plugin
X-KDE-Priority=TopLevel
X-KDE-Submenu=allega a

[Desktop Action SendToMailRcp]
Name=posta elettronica...
Exec=thunderbird -compose "attachment='$(echo %F | sed 's/\\ \\//,\\/\\//g')',to=[some-account],subject=[my-subject],message='path/to/myfile.html',from=[some-my-account]"
Icon=thunderbird 

Now I'd like to add a function for the date, for inserting autmatically today date. I tried with javascript, but javascript is not working in e-mail; I tried with php (message='http://localhost/path/to/file.php'), but if I try to get a php file in thundebird body I don't get anything.

How can I, if possible, get the date in body message?

Answer 1

Solved: this is the code (see my question above for the whole code): Exec=thunderbird -compose "attachment='$(echo %F | sed 's/\ \//,\/\//g')',to=[some account],subject=[some subject],body=arrivo: $(date "+%x") \n partenza:,from=[some account]"
