I would like to do a random block and I don't know how I could success with that Smile

The idea is following. I have always on my page a block at the same place but each times it's displayed, it's another block content displayed. Sometimes it's the user of the month, a photo from gallery another time, a tip of the day another time yet.

Hope it was clear Wink

Do you know php? Do you at least have php functions for each random block you would like to display?

Before to write it myself, I hoped maybe someone has a good and simple idea to do it, or even better, someone has already a block to do it Big Grin

Well, it sounds easy enough. Just write the X functions you want. Then, write a block like this:

PHP Formatted Code
function phpblock_randomBlock()
{
    $i = rand(1, 3);
    switch ($i)
    {
        case 1:
            return phpblock_function1();
        case 2:
            return phpblock_function2();
        case 3:
            return phpblock_function3();
    }
}

 


Hope that helps!

I type this code in to my lib-custom.php file, and get the following error:

Parse error: parse error, unexpected $ in /home/wetcol81/public_html/blog/system/lib-custom.php on line 405

What am I doing wrong?

Thanks!

It would be nice if dgaussin could post the end result if there is any. By chance I am also looking for a random block as follows: (BUT I definitely know nothing about php I just started learning css... I had a look at those random blocks of galeries but I really don`t get it.)


Mambo got a nice feature of "news flashes". It is no more than a block that displays the story text of a story witin a certain topic.

E.g. if there is a topic news_flashes the block shows the storytext or rather just {story_introtext} (or e.g. just the picture included) of one of the stories within topic news_flashes.

So the overall structure would be: Count the number of stories in topic news_flashes, choose one of them, display {story_introtext}


Anybody accidentally about to build such a block???

PHP Formatted Code

function phpblock_randomStory()
{
    global $_TABLES, $_CONF;
    $result = DB_query("SELECT sid,tid,title,introtext FROM {$_TABLES['stories']}
        WHERE (draft_flag = 0) AND (date <= NOW())"

        . COM_getPermSQL ('AND') . " ORDER BY RAND LIMIT 1");

    if( DB_numRows($result) > 0 ){
        $A = DB_fetchArray( $result );
        $retval = '<a href="' . COM_buildUrl( $_CONF['site_url']
                . '/article.php?story=' . $A['sid'] ) . '">'
                . COM_stripslashes($A['title'])
                . '</a> (' . $A['hits'] . ')<br>';
        $retval .= '<div class="introtext">' . COM_stripslashes($A['introtext']) . '</div>';
        return $retval;
   }
}


 
something like that I think
