Re: [Tikiwiki-users] how can I display a random blog?

[paddyboy <kon...@gm...>]

Sylvie,

Cheers thats exactly what i needed.

this is what i will add to lib/tikilib.php

//returns the name of "n" rondom blog
function get_random_blogs($n) {
  $query = "select(*) from 'tiki_pages'";
  
  $cant = $this->getOne($query,array());
  
  //adjust the limit if there are not enough pages
  if ($cant<$n)
       $n = $cant;
       
       //Now that we know the number of pages to pick select ' n' random
positions from '0' to cant
       $positions = array();
       
       for ($i = 0; $i<$n; $i++) {
         $pick = rand (0, $cant - 1);
         
         if(!in_array($pick, $positions))
         $positions[] = $pick;
       }

       // now that we have the positions we just build the data
       $ret = array();
       $temp_max = count($positions);
       for ($i = 0; $i<$temp_max;$i++) {
         $index = $position[$index];
         $query ="select 'blogTitle' from 'tiki_blogs'";
         $name = $this->getOne($query,array(),1,$index);
         $ret[] = $name;
       }

       return $ret;
       }

Does it look right? I'm not sure about the 'blogTitle'.

Thanks again

Paddyboy
