2. Install and modify the plug-in

Download the Empire cms official combined item list attribute filter plug-in, then open the "fieldand.txt" file and copy all the contents in the file to /e/class /userfun.php file (place it anywhere between); (It is recommended to use editing tools such as Dreamweaver or Editplus to modify)

First, in the list of combined fields to be displayed, change "$fieldandvar= 'myarea,sex,age';" change to "$fieldandvar='quyu,zujin,tingshi,fangshi';", this is the list of 4 fields we need to display.

Then we use 4 colors to represent the area of ​​each field code, so as to intuitively analyze their common code points, as shown below:

From the above picture Get the field and field display separator "$fieldexp=' |".

Then analyze according to the format: "Option Description |==|Content 1, Value 1 ## Content 2, Value 2":

Finally get Modified value:

Get the selected option link style according to the code "Quananshan" "$changefieldandcss='select'; ".

According to the above figure, the display spacer format of the combination of options and options: start display character|end display character gets "$valexp='';".

The modified plug-in code is shown in the figure:

Notes:

1. The code is correct, but The reason why the filtering does not work is that the combination of the corresponding fields of the system model is not checked.

2. When filtering, the prompt "The connection you came from does not exist" is because "&classid=column ID" is not specified in the address bar.
