Use custom tags in Empire CMS to achieve the effect of [!--newsnav--]

The following tutorial column of Empirecms will introduce to you how to use customized tags to achieve the effect of [!--newsnav--]. I hope it will be useful to friends who need it. Helped!

Want to modify [!--newsnav--] For example, I want to remove the link of "Homepage>Jinhu Station>Water Conservancy News" and the large column "Jinhu Station" and modify e/class/connect. php file, ReturnClassLink() method.

The following introduces a custom tag to achieve the effect of [!--newsnav--]. If you want to modify it, it is easy to do

Step one: Add the following function to e/class/userfun.php. The function has only one parameter, which is the current ID

//当前位置导航
function user_linknav($classid)
{
        global $empire,$dbtbpre;
        $query="select classname,bclassid,classpath from {$dbtbpre}enewsclass  where classid=".$classid;       
       
        $sql=$empire->query($query);
        //echo "<a href = /"//">首 页</a>";
        while($r=$empire->fetch($sql))
        {
                findparent($r[bclassid]);
                echo " > <a href =/"/".$r[classpath]."/">".$r[classname]."</a>";
        }
}
//当前位置导航，递归查询父栏目
function findparent($classid)
{
        global $empire,$dbtbpre;
        $query="select classname,bclassid,classpath from {$dbtbpre}enewsclass  where classid=".$classid;
       
        $sql=$empire->query($query);
       
        while($r=$empire->fetch($sql))
        {
                findparent($r[bclassid]);
                echo " > <a href =/"/".$r[classpath]."/">".$r[classname]."</a>";
        }
               
}

Step two: Add tags and tag symbols in module management is linknav, the function name is user_linknav, and the label format is [linknav]column ID[/linknav]

Step 3: Add the template variable nav, the content is "Your current location: [linknav]$ GLOBALS[navclassid][/linknav] ”

Finally. You only need to call the template variable [!--temp.nav--] in the template. . . . . . . . . The specific style can be put [!--temp.nav--] in a div. Then just set the style of the div, or modify the function under userfun. . The function is very simple. It is to recursively query upwards based on the current column
