织梦默认的列表页没有筛选功能,但有时候我们做产品列表页的时候,产品的字段比较多,很多人都需要用到筛选功能,这样可以让用户更方便的找到自己所需要的东西,实现这个联动筛选功能需要对织梦进行二次开发,下面就告诉大家如何对织梦进行二次开发实现这个很多人都需要的筛选功能,如下图所示:
首先需要说明的是这个功能需要在模板里面用到php标签,所以需要在后台模板引擎禁用标签里面解除这个标签的禁用,具体方法:
后台——系统——系统基本参数——其它选项——模板引擎禁用标签:php
将这个PHP去掉后保存就可以了!
好了,下面开始正题了。
一、联动筛选单选功能
首先需要修改2个PHP文件,都是include目录下面的。
1、修改arc.listview.class.php文件,这文件改动比较大,建议大家直接下载附件压缩包里面的文件替换,如果你之前对这个文件改动过的话,请在下载下来的压缩包里的这个文件里面搜索有“织梦技术研究中心”这些注释的这些地方,都是修改过的,然自己手动将有注释的代码插入到自己的文件里面!
2、修改extend.func.php文件,在其最后面添加如下代码:
//dedecms联动筛选功能
function wwwcms_filter($str,$stype="inject") {
if ($stype=="inject") {
$str = str_replace(
array( "select", "insert", "update", "delete", "alter", "cas", "union", "into", "load_file", "outfile", "create", "join", "where", "like", "drop", "modify", "rename", "'", "/*", "*", "../", "./"),
array("","","","","","","","","","","","","","","","","","","","","",""),
$str);
} else if ($stype=="xss") {
$farr = array("/\s+/" ,
"/<(\/?)(script|META|STYLE|HTML|HEAD|BODY|STYLE |i?frame|b|strong|style|html|img|P|o:p|iframe|u |em|strike|BR|div|a|TABLE|TBODY|object|tr|td |st1:chsdate|FONT|span|MARQUEE|body|title |\r\n|link |meta|\?|\%)([^>]*?)>/isU",
"/(<[^>]*)on[a-zA-Z]+\s*=([^>]*>)/isU",
);
$tarr = array(" ",
"",
"\\1\\2",
);
$str = preg_replace($farr, $tarr, $str);
$str = str_replace(
array( "<", ">", "'", "\"", ";", "/*", "*", "../", "./"),
array("<",">","","","","","","",""),
$str);
}
return $str;
}
