Filter threads by post icon

I couldn't understand why nobody had created this hack yet, so I made it myself.

This allows users to filter the threads by the icon. They do this by clicking on the icon in the forum thread listing. It then only shows threads with that same post icon.

Switching between pages works, as well as using the column sort functions. It is not designed to work properly with any other sort options but it might.

When posts are filtered, a "Unfilter" link is shown in the column header for thread post icons which, when clicked, removes the filter and returns the view to page 1.

Only 1 file needs to be modified, and 2 templates.

In forumdisplay.php, find

PHP Code:

globalize($_REQUEST, array('perpage' => INT, 'pagenumber' => INT, 'daysprune' => INT)); 


Replace with:

PHP Code:

//Post icon filter hack
//globalize($_REQUEST, array('perpage' => INT, 'pagenumber' => INT, 'daysprune' => INT));
globalize($_REQUEST, array('perpage' => INT, 'pagenumber' => INT, 'daysprune' => INT, 'picon'=> INT));
//*Post icon filter hack 


Find:

PHP Code:

    if ($daysprune != -1)
    {
        $datecut = "AND lastpost >= " . (TIMENOW - ($daysprune * 86400));
        $show['noposts'] = false;
    }
    else
    {
        $datecut = '';
        $show['noposts'] = true;
    } 


And add immediately after it:

PHP Code:

//Post icon filter hack
    if ($picon > 0 && is_numeric($picon) && $picon < 5000) { //who knows if all this is necessary - better safe than sorry
      $pqr = " AND thread.iconid = '$picon' ";
      $datecut .= $pqr;
      } else
        $picon = "";
//*post icon filter hack 


Find:

PHP Code:

        $pagenav = construct_page_nav($totalthreads, "forumdisplay.php?$session[sessionurl]f=$forumid", "&sort=$sortfield&order=$sortorder&pp=$perpage&daysprune=$daysprune"); 


Replace with:

PHP Code:


//Post icon filter hack
//        $pagenav = construct_page_nav($totalthreads, "forumdisplay.php?$session[sessionurl]f=$forumid", "&sort=$sortfield&order=$sortorder&pp=$perpage&daysprune=$daysprune");
        $pagenav = construct_page_nav($totalthreads, "forumdisplay.php?$session[sessionurl]f=$forumid", "&sort=$sortfield&order=$sortorder&pp=$perpage&daysprune=$daysprune&picon=$picon");
//*post icon filter hack 


UPDATE 1.00 TO 1.01 ADD THIS MODIFICATION
Find:

PHP Code:

    $sorturl = "forumdisplay.php?$session[sessionurl]f=$forumid&daysprune=$daysprune"; 


And add immediately after it:

PHP Code:

//Post icon filter hack
    if ($pqr) {
      $noiconurl = $sorturl;
      $sorturl .= "&picon=$picon";
      }
//*post icon filter hack 


Ok, for the templates, in threadbit, find:

<img src="$thread[threadiconpath]" alt="$thread[threadicontitle]" border="0" />

And replace it with:

<a href="$sorturl&amp;picon=$thread[threadiconid]"><img src="$thread[threadiconpath]" alt="$thread[threadicontitle]" border="0" /></a>

Then in FORUMDISPLAY find:

	<if condition="$show['threadicons']">
		<td class="thead" colspan="2">&nbsp;</td>
	<else />
		<td class="thead">&nbsp;</td>
	</if>

And replace it with:

	<if condition="$show['threadicons']">
      <if condition="$picon">
        <td class="thead" colspan="2"><a href="$noiconurl">Unfilter</a></td>
      <else />
		<td class="thead" colspan="2">&nbsp;</td>
	  </if>
	<else />
		<td class="thead">&nbsp;</td>
	</if>

It's working fine on our board. If you have any questions, just ask!

I've wanted this for a bit, but couldn't figure it out. Thanks, this works perfectly.

[HeloHi]

This is great

[HeloHi]

where you have:

PHP Code:

if ($daysprune != -1) 
    { 
        $datecut = "AND lastpost >= " . (TIMENOW - ($daysprune * 86400)); 
        $show['noposts'] = false; 
    } 
    else 
    { 
        $datecut = ''; 
        $show['noposts'] = true; 
    } 


I have:

PHP Code:

if (!$daysprune)
{
    if ($bbuserinfo['daysprune'] != 0)
    {
        $daysprune = $bbuserinfo['daysprune'];
    }
    else
    {
        $daysprune = iif($foruminfo['daysprune'], $foruminfo['daysprune'], 30);
    }
} 


and when I follow the instructions I get an error:

Parse error: parse error, unexpected T_ELSE in /home/parapla/public_html/forums/forumdisplay.php on line 514

where line 514 is

PHP Code:

$daysprunesel = iif($daysprune == -1, 'all', $daysprune); 


Forgive me but I am extremely novice about these things! What do I need to do to make this work?

You may want to update to 3.0.7 first.

I have updated, I thought. Is that code from the older version or something?

See: www.forums.paraplanet.com it is 3.07


Edit: Hehe I hadn't updated my profile, sorry about that! Any thoughts on what I can do?

EDIT: As mentioned below, he needed to look further down in the code to find the right piece.

You are at the wrong part of the code. Keep looking in the php file and you will find that code JMPZ is talking about.

Where is "$noiconurl" defined? I'm just wondering because mine won't 'unfilter' and since I don't see that defined, I'm thinking that may be the culprit.

That is exactly it! Thanks so much! I am trying to get better :surprised:
