Discuz中的分页函数

水平有限 其中的错误敬请指正
[php]//先看下几个参数吧
//$num 为总共的条数 比如说这个分类下共有15篇文章
// $perpage为每页要显示的条数
//$curpage为当前的页数
//$mpurl为url的除去表示页数变量的一部分，
//$page为$multipage这个字符串中要显示的表示页数的变量个数
//$maxpages为最大的页数值 此函数最后有一句$maxpage = $realpages;
function multi($num, $perpage, $curpage, $mpurl, $maxpages = 0, $page = 10, $autogoto = TRUE, $simple = FALSE) {
global $maxpage;
$ajaxtarget = !emptyempty($_GET['ajaxtarget']) ? " ajaxtarget=\"".dhtmlspecialchars($_GET['ajaxtarget'])."\" " : '';
$multipage = '';
$mpurl .= strpos($mpurl, '?') ? '&' : '?';
$realpages = 1;
//判断总条数是否大于设置的每页要显示的条数
if($num > $perpage) {
//设置在$multipage中当前页数之前还要输出几个页数
$offset = 2;
$realpages = @ceil($num / $perpage);
//总共的页数（不知道$maxpages的意思），这里假设是15条
$pages = $maxpages && $maxpages < $realpages ? $maxpages : $realpages;
//如果总页数小于multipage中要输出的页数$page，则只输出到实际页数为止
if($page > $pages) {
$from = 1;
$to = $pages;
//如果大于的话，就要输出$page个页数（我们假设的的15条就符合这个条件）
} else {
$from = $curpage - $offset;
$to = $from + $page - 1;
//假设curpage为4，目前为止，from为2，to为11
//下面假设curpage为1
if($from < 1) {
$to = $curpage + 1 - $from;（****不明白***）
$from = 1;
//目前为止from为1，to为3
if($to - $from < $page) {
//因为这里的前提条件是总条数大于page，所以，如果$to-$from小于page的话显然达不到目的，应把$to设置为$page
$to = $page;
}//目前为止 from为1 ，to为10
} elseif($to > $pages) {//to是不可以大于总页数的
$from = $pages - $page + 1;
$to = $pages;
}
}
$multipage = ($curpage - $offset > 1 && $pages > $page ? '<a href="'.$mpurl.'page=1" class="first"'.$ajaxtarget.'>1 ...</a>' : '').
($curpage > 1 && !$simple ? '<a href="'.$mpurl.'page='.($curpage - 1).'" class="prev"'.$ajaxtarget.'>‹‹</a>' : '');
for($i = $from; $i <= $to; $i++) {
$multipage .= $i == $curpage ? '<strong>'.$i.'</strong>' :
'<a href="'.$mpurl.'page='.$i.($ajaxtarget && $i == $pages && $autogoto ? '#' : '').'"'.$ajaxtarget.'>'.$i.'</a>';
}
$multipage .= ($curpage < $pages && !$simple ? '<a href="'.$mpurl.'page='.($curpage + 1).'" class="next"'.$ajaxtarget.'>››</a>' : '').
($to < $pages ? '<a href="'.$mpurl.'page='.$pages.'" class="last"'.$ajaxtarget.'>... '.$realpages.'</a>' : '').
(!$simple && $pages > $page && !$ajaxtarget ? '<kbd><input type="text" name="custompage" size="3" onkeydown="if(event.keyCode==13) {window.location=\''.$mpurl.'page=\'+this.value; return false;}" /></kbd>' : '');
$multipage = $multipage ? '<div class="pages">'.(!$simple ? '<em> '.$num.' </em>' : '').$multipage.'</div>' : '';
}
$maxpage = $realpages;
return $multipage;
}

而且Discuz！的很多处理机制也被很多程序作者引用了，我有印象的比如sablog
我自己就是把discuz改的巫七麻西去做这种东西。
[php]if($num > $perpage) {
$page = 11;
$offset = 5;
$realpages = @ceil($num / $perpage);
$pages = $maxpages && $maxpages < $realpages ? $maxpages : $realpages;
if($page > $pages) {
$from = 1;
$to = $pages;
} else {
$from = $curpage - $offset;
$to = $from + $page - 1;
if($from < 1) {
$to = $curpage + 1 - $from;
$from = 1;
if($to - $from < $page) {
$to = $page;
}
} elseif($to > $pages) {
$from = $pages - $page + 1;
$to = $pages;
}
}
$multipage['left'] = $curpage > 1 ? '<a href="'.$mpurl.($curpage - 1).'.html">上一页</a> ' : '';
$multipage['right'] = '';
for($i = $from; $i <= $to; $i++) {
$multipage['left'] .= $i < $curpage ? '<a href="'.$mpurl.$i.'.html">'.$i.'</a> ' : '';
$multipage['right'] .= $i > $curpage ? '<a href="'.$mpurl.$i.'.html">'.$i.'</a> ' : '';
}
$multipage['right'] .= $curpage < $realpages ? '<a href="'.$mpurl.($curpage + 1).'.html">下一页</a> ' : '';
}
[/php]
$multipage['left']和$multipage['right']是分别放在左右两边的，就是ijavascript.cn的效果！
CODE:
function codedisp($code) {[php]function codedisp($code) {global $discuzcodes;
$discuzcodes['pcodecount']++;
$code = htmlspecialchars(str_replace('\\"', '"', preg_replace("/^[\n\r]*(.+?)[\n\r]*$/is", "\\1", $code)));
$discuzcodes['codehtml'][$discuzcodes['pcodecount']] = tpl_codedisp($discuzcodes, $code);
$discuzcodes['codecount']++;
return "[\tDISCUZ_CODE_$discuzcodes[pcodecount]\t]";
}
global $discuzcodes;
$discuzcodes['pcodecount']++;
$code = htmlspecialchars(str_replace('\\"', '"', preg_replace("/^[\n\r]*(.+?)[\n\r]*$/is", "\\1", $code)));
$discuzcodes['codehtml'][$discuzcodes['pcodecount']] = tpl_codedisp($discuzcodes, $code);
$discuzcodes['codecount']++;
return "[\tDISCUZ_CODE_$discuzcodes[pcodecount]\t]";
}

This php program will convert jass text to a formed style.
To use this one you need to set a string variable and convey it to the function jassc.
The function jassc will return the formed jass text as a string.
------------------------------
Be care that the conveyed text should less than 5000 bytes.
If the text is a much longer,the function will cut the spare bytes.
The output string is html format.
------------------------------
The infomation about which things should be convert will write in jassstyle.txt .
The color and font style will be seen after every title.
