Probably a very newbie question...

[jamesi]

I have some coding for a Pligg site I'm running. I want to show only certain categories on the front page... I have this code, which means it shows one category:

 

// Find the current URL
$domain = $_SERVER['HTTP_HOST'];
$url = "http://" . $domain . $_SERVER['REQUEST_URI'];
// echo $url.'<br />';
// echo $my_base_url.$my_pligg_base.'/<br />';
if (($url == $my_base_url.$my_pligg_base.'/') || ($url == $my_base_url.$my_pligg_base.'/index.php')) {
    // Show the category ID # '13' by default.
    // echo 'Homepage';
    $search->category = "2";
}

 

But I'm not sure of the correct way to show more than one category. Tried repeating the $search category line with a different number, tried commas, tried everything I can think of. The people at Pligg weren't very helpful either!

 

Thanks a lot!

use array,

 

$search->category = array(1,2,3,4);

 

if you are using mysql database then query will be

 

$imploded_array = implode(",",$search->category );
select * from tableName where id IN ($imploded_array);

 

code is not tested...

can you post the full code???

// figure out what "page" of the results we're on

The main code in question is:

 

// Find the current URL
$domain = $_SERVER['HTTP_HOST'];
$url = "http://" . $domain . $_SERVER['REQUEST_URI'];
// echo $url.'<br />';
// echo $my_base_url.$my_pligg_base.'/<br />';
if (($url == $my_base_url.$my_pligg_base.'/') || ($url == $my_base_url.$my_pligg_base.'/index.php')) {
    // Show the category ID # '13' by default.
    // echo 'Homepage';
$search->category = "2";
