Custom Tag

Hallo!
I tried to proceed a bit further.

I took the example from the webpage of “contactform7” (https://contactform7.com/2015/01/10/adding-a-custom-form-tag/ )

add_action( 'wpcf7_init', 'custom_add_form_tag_clock' );
 
function custom_add_form_tag_clock() {
    wpcf7_add_form_tag( 'clock', 'custom_clock_form_tag_handler' ); // "clock" is the type of the form-tag
}
 
function custom_clock_form_tag_handler( $tag ) {
    return date_i18n( get_option( 'time_format' ) );
}

then I replaced the “return date” command with the following

return do_shortcode( '[table-cell id=7 cell=B9 /]' ); // corresponding cell in line B

Which returns the content of a particular cell of a table.
Specifying now [clock] in the form, shows the content of the cell.

What I need now, is to assign this content to a form-tag (like a datalist), so to be able to include it directly in the Email. Something like

[datalist clock B9] that assigns the content of the cell “B9” in a table to the attribute [clock], that I can then use in the Mail and in the extensions like “Convert CF7 to Pdf”.

Thank you for any help on that!

Hi! Just want to say that I solved the problem by myself with the help of this example by morgyface

https://gist.github.com/morgyface/56474f0a37abb7d622880daf6eff6e40

and a bit of php string concatenation.
So no answer here, too bad, but I can close the topic.
