Forum Questions

[GaryCXJk]

Well, I have some questions regarding the forum. I'm making one myself, with own portal and own stuff.

Anyways here are the questions:

1) How were the tags done? Did DeKoffie used $preg_replace? Can you give me an example of the italic tags?

2) How were the page systems done? Like, if there are more than 15 posts, then you can click on a certain page to go to for example page 16 to 30.

3) What is that TYPE=MyISAM; used for in MySQL?

Soryy for replying so late, anyhow here i am! ;)

1) italic is easy, so i'll show also the examples of auto links and PHP code:

$bericht = str_replace("[I]", "<i>", $bericht);

$bericht = eregi_replace("(^|[>[:space:]\n])([[:alnum:]]+)://([^[:space:]]*)([[:alnum:]#?/&=])([<[:space:]\n]|$)","\\1<a href=\"\\2://\\3\\4\" target=\"_blank\">\\2://\\3\\4</a>\\5", $bericht);

$bericht = preg_replace('_\[PHP\](.*?)\[/PHP\]_ise', "highlight(trim(stripslashes(' \\1 ')))", $bericht); 



2) simply count the total posts at the beginning, then read you "howmanyperpage" var and split it.
Example:

$total=43;
$perpage=15;
$actualpage=2;
$pagestart = ($perpage * $actualpage) - $perpage;
$pages=intval($total/$perpage)+1; //will be 3


Then add this to you sql query:
LIMIT $pagestart, $perpage

And create the "pages" link like this:

if($num_pages > 1) {
echo "Pages : <b>";
for ($i = 1; $i <= $num_pages; $i++) {
if ($i != $page) {
echo "thelink.php?page=$i>$i</a> ";
} else {
echo "$i ";
}
}
}
