Tweak - Highlight letters in Reviews module

Posted: Mon Feb 23, 2004 1:06 am

This tweak will highlight any and all letters in The Reviews module if they have content and only letters with content will become a link, no sense searching in a letter if we already know it doesn't have any entries:

Open modules/Reviews/index.php and replace the entire alpha function (the very first function) with:

Code:

function alpha() { 


    global $module_name, $db, $prefix; 


    $alphabet = array ("A","B","C","D","E","F","G","H","I","J","K","L","M", 


                       "N","O","P","Q","R","S","T","U","V","W","X","Y","Z","1","2","3","4","5","6","7","8","9","0"); 


    $num = count($alphabet) - 1; 


    echo "<center>[ "; 


    $counter = 0; 


    while (list(, $ltr) = each($alphabet)) { 


   $ltr_num = $db->sql_numrows($db->sql_query("SELECT * FROM ".$prefix."_reviews WHERE UPPER(title) LIKE '$ltr%'")); 


   if ($ltr_num == 0) { 


        $altr = "$ltr"; 


        } else { 


        $altr = "<a href=\"modules.php?name=$module_name&rop=$ltr\"><b><font class=title>$ltr</font></b></a>"; 


        } 


        echo "$altr"; 


        if ( $counter == round($num/2) ) { 


            echo " ]\n<br>\n[ "; 


        } elseif ( $counter != $num ) { 


            echo " ;;| ;;\n"; 


        } 


        $counter++; 


    } 


    echo " ]</center><br><br>\n\n\n"; 


    echo "<center>[ <a href=\"modules.php?name=$module_name&rop=write_review\">"._WRITEREVIEW."</a> ]</center><br><br>\n\n"; 


}
