phpcms recommendation bit cannot call custom fields_PHP tutorial

By default, phpcms cannot use the recommended bit to call custom fields. Directly write {pc:content action="position" posid="30" catid="24" order="listorder DESC" num="4 "} will not go wrong, but the data cannot be called and the display is blank.

Calling code

　01.{pc:content action="position" posid="30" catid="24" order="listorder DESC" num="4"} 02.{loop $data $n $r} 03.{ $r["kk_date"]} 04.{/loop} 05.{/pc} Code description

action="position" content recommendation position list

posid="30"Call the content with the recommended ID 30

catid="24" calls the content under column ID 24

I won’t talk about order="listorder DESC" order

num="4" displays four pieces of content

After completing the above code, it is generally still unable to be displayed. The fields in the phpcms background model management still need to be set.

　phpcms model settings

Step 1: Successfully log in to the phpcms backend.

Step 5: Then click Modify again on the article you want to display normally, and then save it to take effect (just modify and save if you don’t change anything).

Step 6: Update the website cache to take effect.
