Description

A little patch to offer random value on listNum with the keyword 'rand' :

File class.tslib_content.php - Line 3347 and next

function listNum($content,$listNum,$char) {
        $char = $char ? $char : ',';
        if (t3lib_div::testInt($char))    {
            $char = chr($char);
        }
        $temp = explode($char,$content);
        $last = ''.(count($temp)-1);
+        if ($listNum = 'rand') $listNum = rand(count($temp));
        $index=$this->calc(eregi_replace('last',$last,$listNum));
        return $temp[$index];
    }

Sorry a error when i key in. You have to read :

+ if ($listNum == 'rand') $listNum = rand(0,count($temp)-1);

Nice Feature

maybe this inspires..

http://typo3.org/documentation/document-library/extension-manuals/dam_pages/0.1.2/view/1/3/

the way the random function is realized there is more comfortable.

The usage of Listnum as Start value for rand is pretty nice.

What has to be done to get this feature into core?

I'm using something like this with a XCLASS but it would be nice to see this in core.

I agree this would be cool to have in core. I needed similar functionality and am now using an XCLASS as suggested by Frans.

that would be a great feature.
the code above doesen't work anymore with php5.3 and typo3 4.4 it should read:

+ if ($listNum === 'rand') $listNum = rand(0,count($temp)-1);

because of:
if(0 == 'anystring') //returns TRUE

Is Peter Niederlag still taking care of this issue? If not I could take care for a patch and make an RFC.

Use the following TS to test-drive the patch from Gerrit:

- Create a page and set it's subtitle field to someting comma-separated like "foo,bar,baz"
- Add a TS template record on that page with the lines below (adapt if your PAGE object is not "page")
- Clear all caches and test-drive that page in the frontend

Expected behaviour after applying the changes from Gerrit:
The subtitle field changes upon every reload

Typoscript code for testing:
page.5 = COA_INT
page.5 {
10 = TEXT
10 {
field = subtitle
stdWrap.listNum = rand
}
}
