HQY 一个和谐有爱的空间

常见于DZ论坛，但是zblog也可以实现的，以下内容仅做备忘。

主题include.php里面引入文件“search_config.php”：

require dirname(__FILE__) . DIRECTORY_SEPARATOR . 'plugin

arch_config.php';并且挂载接口：Add_Filter_Plugin('Filter_Plugin_Search_Begin','主题ID_SearchMain');

search_config.php文件代码：

global $zbp;

foreach ($GLOBALS['Filter_Plugin_ViewSearch_Begin'] as $fpname => &$fpsignal) {

$fpreturn = $fpname();

if ($fpsignal == PLUGIN_EXITSIGNAL_RETURN) {

$fpsignal=PLUGIN_EXITSIGNAL_NONE;

return $fpreturn;

}

}

if(!$zbp->CheckRights($GLOBALS['action'])){

Redirect('./');

}

$q = trim(htmlspecialchars(GetVars('q','GET')));

$qc = '' . $q . '';

$articles = array();

$category = new Metas;

$author = new Metas;

$tag = new Metas;

$zbp->title = '有关【'.$q.'】的内容：';

$template = $zbp->option['ZC_INDEX_DEFAULT_TEMPLATE'];

if($zbp->template->hasTemplate('search')){

$template = 'search';//搜索列表页模版名称

}

$w=array();

$w[]=array('=','log_Type','0');

$cid = trim(htmlspecialchars(GetVars('cid','GET')));//传入的分类ID

if($cid){

$w[]=array('search','log_CateID',$cid);

}

if($q){

$w[]=array('search','log_Content','log_Intro','log_Title',$q);

}else{

Redirect('./');

}

if(!($zbp->CheckRights('ArticleAll')&&$zbp->CheckRights('PageAll'))){

$w[]=array('=','log_Status',0);

}

if($cid){

$pagebar=new Pagebar('{%host%}search.php?{q='.$q.'}&cid='.$cid.'&{page=%page%}',false);

} else {

$pagebar=new Pagebar('{%host%}search.php?{q='.$q.'}&{page=%page%}',false);

}

$pagebar->PageCount=$zbp->displaycount;

$pagebar->PageNow=(int)GetVars('page','GET')==0?1:(int)GetVars('page','GET');

$pagebar->PageBarCount=$zbp->pagebarcount;

$articles = $zbp->GetArticleList(

'*',

$w,

array('log_PostTime' => 'DESC'), array(($pagebar->PageNow - 1) * $pagebar->PageCount, $pagebar->PageCount),

array('pagebar' => $pagebar),

null

);

if ($articles){

foreach($articles as $article){

$intro = preg_replace('/[\r\n\s]+/', '', trim(主题ID_SubStrStartUTF8(TransferHTML($article->Content,'[nohtml]'),$q,150)) . '...');

$article->Intro = str_ireplace($q,$qc,$intro);

$article->Title = str_ireplace($q,$qc,$article->Title);

}

$zbp->template->SetTags('主题IDSearchSubtitle','');

}else{

$zbp->title = '没有找到有关【'.$q.'】的内容！';

$zbp->template->SetTags('主题IDSearchSubtitle','');

$pagebar='';

foreach($articles as $article){

$article->Intro = preg_replace('/[\r\n\s]+/', '', trim(SubStrUTF8(TransferHTML($article->Intro,'[nohtml]'),150)).'...');

}

}

$zbp->header .= '' . "\r\n";

$zbp->template->SetTags('title', $zbp->title);

$zbp->template->SetTags('articles',$articles);

$zbp->template->SetTags('page',1);

$zbp->template->SetTags('pagebar',$pagebar);

if ($zbp->template->hasTemplate('search')) {

$zbp->template->SetTemplate($template);

} else {

$zbp->template->SetTemplate('index');

}

foreach ($GLOBALS['Filter_Plugin_ViewList_Template'] as $fpname => &$fpsignal) {

$fpreturn=$fpname($zbp->template);

}

$zbp->template->Display();

RunTime();

die();}?>

此文件中引入的文件searchstr.php代码如下：

*  获取UTF8格式的字符串的子串

* @param string $sourcestr 源字符串

* @param int $startstr 开始字串子串

* @param int $cutlength 子串长度

* @return string

*/function 主题ID_SubStrStartUTF8($sourcestr,$startstr,$cutlength) {

global $zbp;

if( function_exists('mb_substr') && function_exists('mb_internal_encoding') && function_exists('mb_stripos') ){

mb_internal_encoding('UTF-8');

return mb_substr($sourcestr, mb_stripos($sourcestr, $startstr), $cutlength);

}

if( function_exists('iconv_substr') && function_exists('iconv_set_encoding') && function_exists('iconv_strpos') ){

iconv_set_encoding ( "internal_encoding" ,  "UTF-8" );

iconv_set_encoding ( "output_encoding" ,  "UTF-8" );

return iconv_substr($sourcestr, iconv_strpos($sourcestr, $startstr), $cutlength);

}

$returnstr = '';

$i = stripos($sourcestr, $startstr);

$n = 0;

$str_length = strlen($sourcestr); //字符串的字节数

while (($n 

$temp_str = substr($sourcestr, $i, 1);

$ascnum = Ord($temp_str); //得到字符串中第$i位字符的ascii码

if ($ascnum >= 224) //如果ASCII位高与224，

{

$returnstr = $returnstr . substr($sourcestr, $i, 3); //根据UTF-8编码规范，将3个连续的字符计为单个字符

$i = $i + 3; //实际Byte计为3

$n++; //字串长度计1

} elseif ($ascnum >= 192) //如果ASCII位高与192，

{

$returnstr = $returnstr . substr($sourcestr, $i, 2); //根据UTF-8编码规范，将2个连续的字符计为单个字符

$i = $i + 2; //实际Byte计为2

$n++; //字串长度计1

} elseif ($ascnum >= 65 && $ascnum <= 90) //如果是大写字母，

{

$returnstr = $returnstr . substr($sourcestr, $i, 1);

$i = $i + 1; //实际的Byte数仍计1个

$n++; //但考虑整体美观，大写字母计成一个高位字符

} else //其他情况下，包括小写字母和半角标点符号，

{

$returnstr = $returnstr . substr($sourcestr, $i, 1);

$i = $i + 1; //实际的Byte数计1个

$n = $n + 0.5; //小写字母和半角标点等与半个高位字符宽...

}

}

if ($str_length > $cutlength) {

$returnstr = $returnstr;

}

return $returnstr;}

模板中需要改写一下：

{php}

$cid ='';

echo 主题ID_Cate($cid);

{/php}    <

lect>

其中主题ID_Cate函数是调用所有分类，如需调用部分分类，可另外设置：

function 主题ID_Cate($zdycate){

global $zbp;

$Catenews=$zbp->GetCategoryList(array('*'),null);

$s = '';

foreach ($Catenews as $Catenew) {

if($zdycate==$Catenew->ID){

$s .='ID.'" selected="selected" >'.$Catenew->Name.'';

} else {

$s .='ID.'">'.$Catenew->Name.'';

}

}

if($zdycate==""){

$s .='所有分类';

} else {

$s .='所有分类';

}

return $s;}
