帝国cms二次开发最终效果
二次开发修改方法
打开/e/search/index.php
1、找到：
//处理关键字
function SearchDoKeyboardVar($keyboard){
$keyboard=RepPostVar2(trim($keyboard));
$keyboard=str_replace(' ','',$keyboard);
return $keyboard;
}
修改为：
//处理关键字
function SearchDoKeyboardVar($keyboard){
$keyboard=RepPostVar2(trim($keyboard));
//$keyboard=str_replace(' ','',$keyboard);
/*xuan 搜索关键字优化*/
$keyboard=preg_replace('/[s]+/s', ' ', $keyboard);
/*xuan 搜索关键字优化*/
return $keyboard;
}
2、找到：
//(有两处，修改第二处)
$where=$f." LIKE '%".$keyboard."%'";
7.0版为：
$where=$f." LIKE '%".str_replace(" ","%",$keyboard)."%'";
修改为：
/*xuan 搜索关键字优化*/
preg_match_all("/[^s]+/s",$keyboard,$keyarr);
foreach ($keyarr[0] as $val){
$tj.=$f." like '%".$val."%' or ";
}
$where=substr($tj,0,-4);
/*xuan 搜索关键字优化*/这样即可。
懒人直接复制以下代码替换/e/search/index.php中所有代码即可
