• Hello Fabrik Community

    Fabrik is now in the hands of the development team that brought you Fabrik for Joomla 4. We have recently transitioned the Fabrik site over to a new server and are busy trying to clean it up. We have upgraded the site to Joomla 4 and are running the latest version of Fabrik 4. We have also upgraded the Xenforo forum software to the latest version. Many of the widgets you might have been used to on the forum are no longer operational, many abandoned by the developers. We hope to bring back some of the important ones as we have time.

    Exciting times to be sure.

    The Fabrik 4.0 Official release is now available. In addition, the Fabrik codebase is now available in a public repository. See the notices about these in the announcements section

    We wish to shout out a very big Thank You to all of you who have made donations. They have really helped. But we can always use more...wink..wink..

    Also a big Thank You to those of you who have been assisting others in the forum. This takes a very big burden off of us as we work on bugs, the website and the future of Fabrik.

Replace a specific char in a string

TroubleAllWays

New Member
I am looking for a solution to replace a char (in my case the space) when entering a string in a field .
Here's my example:
I shift copy a sting like this: AGT TAA CCA ATA TAG
In the saved data the spaces should be remove, so this should be in the field after saving the dataset: AGTTAACCAATATAG

Is there anybody, who got an idea to solve this problem? Would be great.

I already tried in the Validation section:
________
Action: php
published - both - both -
Must validate: yes

PHP Code:
$str = ' ';
echo str_replace(' ', '', $str);

(I've read somewhere, that <?PHP has to be omitted)

Replace
________

But nothing happens when I copy a string with space into the field.
 
Something like this should do for just spaces:

return str_replace(' ', '', $data);

For all whitespaces including tabs and line ends etc:

return preg_replace('/\s+/', '', $data);

PS. Not tested.
 
We are in need of some funding.
More details.

Thank you.
