using the value of a variable inside another one

Hello,
I have 2 fields :

- field 1 :

video_youtube (contains a youtube URL
- Field 2 : bande_son_youtube (contains an URL with transcode the youtube video into a MP3 file)

The field 2 is an hidden field which contains in field specific properties - Value creation the following text as default value :
({qrcodeslocal} is a plugin which transforms an URL into a QR code.


I get in public access the QR code but the url is not replaced by the value of video_youtube.
I only get as URL the following text : {{video_youtube##0}}


How can I use the value of youtube_video inside bande_son_youtube

thank you very much for help

Best regards

Hello,
Field 1: video_youtube is a text field?
and Field 2 is also a text field right ?

where did you put:

{{video_youtube##0}}

you need to put it a prefix or suffix value parameter or in opentag / closetag parameters

Thank you very much.

this field is a hidden field. So I have put [yts]{qrcodeslocal} convert2mp3.net/c-mp3.php?url={{video_yo...e##0}}{/qrcodeslocal }[/yts] inside the
field specific properties-value creation to get it as default value.

If the specific properties-value creation remains empty I don't get the field in the public page.

So I have put [yts] (the beginning of the field content - tag used in nonumber rereplacer) and the remaining part of the field in the suffix.

Now it's working.

In a future value of FC could it be possible to get the {{filed##0}} executed also inside the default value and not only in the prefix/suffix parameter.

best regards

Michel
