Shortcodes in the sidebar

@alex

Thank for the reply.

My question is not related to post_meta.
The “id” in the shortcode can be anything.

i.e.

[myinfo tax_id=1], [myinfo anynumber=8] etc.

All what I want to achieve is to allow the front end user to type only a number (a figure) instead of writing the whole short code.

For [myinfo tax_id=1], I want the user to enter only “1” (Not “[myinfo tax_id=1]”).
For [myinfo anynumber=8], I want the user to enter only “8” (Not “[myinfo anynumber=8]”).

I know this can be achieved by a filter.
Unfortunately, I cannot write one for the gd shortcode.

Thanks
