Random Image for SMF Gallery Mod

[deniz]

add fallowing code before "?>" in ssi.php

Code Select Expand

function ssi_galleryrandom()
{
global $scripturl,$db_prefix,$modSettings,$boardurl;

if(empty($modSettings['gallery_url']))
{
$modSettings['gallery_url'] = $boardurl . '/gallery/';
}

$request = db_query("SELECT thumbfilename,ID_PICTURE FROM

{$db_prefix}gallery_pic GROUP BY thumbfilename ORDER BY RAND() LIMIT 1", __FILE__,

__LINE__);
$row = mysql_fetch_assoc($request);
mysql_free_result($request);
echo' <center><a href="', $scripturl, '?action=gallery;sa=view;id=',

$row['ID_PICTURE'], '"><img src="',  $modSettings['gallery_url'] .

$row['thumbfilename'] ,'" /></a></center>'

;}

and add a php block:

Code Select Expand

ssi_galleryrandom();
echo '<center>
<br>
<a href="http://www.yoursite.com/forum/index.php?action=gallery">Show Gallery</a>
<br>
<a href="http://www.yoursite.com/forum/index.php?action=gallery;sa=add;cat=1">Add Picture</a>
</center>';



change "yoursite.com/forum" depends on your site..

Code Select Expand

ssi_galleryrandom();
echo '<center>
<br>
<a href="http://www.yoursite.com/forum/index.php?action=gallery">Show Gallery</a>
<br>
<a href="http://www.yoursite.com/forum/index.php?action=gallery;sa=add;cat=1">Add Picture</a>
</center>';



change "yoursite.com/forum" depends on your site..

Code Select Expand

global $scripturl;
ssi_galleryrandom();
echo '<center>
<br>
<a href="',$scripturl,'?action=gallery">Show Gallery</a>
<br>
<a href="',$scripturl,'?action=gallery;sa=add;cat=1">Add Picture</a>
</center>';

Or let the php do it for you. 

Note that if this is the only place you're going to display a random image, you can skip modifying the SSI.php and just replace the ssi_galleryrandom() call in the block with the code from the function itself (no FTP'ing, no problems with redo-ing the change at the next upgrade).

hey could one of u guys add a "condition check" for the links for gallery and add a pic links?

So that they only appear to members instead of everyone?

that would make the code complete in my view

Code Select Expand

global $scripturl, $user_info;
ssi_galleryrandom();
if (!$user_info['is_guest']) {
echo '<center>
<br>
<a href="',$scripturl,'?action=gallery">Show Gallery</a>
<br>
<a href="',$scripturl,'?action=gallery;sa=add;cat=1">Add Picture</a>
</center>';
}


Don't know what you mean by "add a pic links". As I read the code, the thumbnail is a link to the full picture Gallery display.

[akulion]

oh no i meant that :

Code Select Expand


if (!$user_info['is_guest']) {
echo '<center>Please register so you can add your pics to the gallery';
}
else
{
echo '<center>
<br>
<a href="',$scripturl,'?action=gallery">Show Gallery</a>
<br>
<a href="',$scripturl,'?action=gallery;sa=add;cat=1">Add Picture</a>
</center>';
}


is that correct?

[jacortina]

Nope. But it's exactly 100% opposite of what you want.

Change:
if (!$user_info['is_guest'])

To:
if ($user_info['is_guest'])
