Whether it's index.php on the homepage or single.php on a single log page, there are always two lines of code at the end of the file:
& lt？ PHP get _ sidebar()； ? & gt
& lt？ PHP get _ footer()； ? & gt
We need to explain it in two situations:
The first case: If you don't use theme widgets, you can call different sidebars in only two steps.
Find the single.php file:
& lt？ PHP get _ sidebar()； ? & gt
Revised as:
& lt？ PHP include _ once(" sidebar 2 . PHP ")； ? & gt
Upload and overwrite single.php, refresh, done!
In the second case, if widgets are used, it takes only 4 steps to call different sidebars.
Repeat the steps for creating a new sidebar2.php in the first case.
Then open function.php and find a similar code:
& lt？ Server-side programming language (abbreviation of professional hypertext preprocessor)
if(function _ exists(' register _ sidebar '))
Register_sidebar (array (
before _ widget ' = & gt'',
after _ widget ' = & gt,
before _ title ' = & gt'
));
These lines of code are an "application", applying for a widget from Wordpress. If you want to display different sidebar on different surfaces, and this sidebar supports widgets, you need to write an "application" to Wordpress to apply for a widget. Moreover, this application has a name, and the name format should be written as follows:'' name' =>' Name', which should be consistent with the names of some widgets called by sidebar2.php later, so it should be written as follows:
if(function _ exists(' register _ sidebar '))
Register_sidebar (array (
Name' => Sidebar 2',
before _ widget ' = & gt& ltid = " % 1 $ s " class = " widget % 2 $ s " > ",
after _ widget ' = & gt,
before _ title ' = & gt'
,
' after _ title ' = & gt'
,
));
Add the above sentence to the original "application" Now, you need to change the code that originally called the default widget in sidebar2.php to call sidebar2, which is a widget of a new application. Open Sidebar2.php and find this code:
& lt？ PHP if(function _ exists(' dynamic _ sidebar ')& amp； & ampdynamic_sidebar() ) : else:？ & gt
& lt？ php endif？ & gt
Revised as:
& lt？ PHP if(function _ exists(' dynamic _ sidebar ')& amp； & ampdynamic _ sidebar(sidebar 2)):else:？ & gt
& lt？ php endif？ & gt
Now do the last job, open the single.php and find:
& lt？ PHP get _ sidebar()； ? & gt
Revised as:
& lt？ PHP include _ once(" sidebar 2 . PHP ")； ? & gt
Save the file and upload it.
Now, if you go to the Widgets settings in the background, you will find that there is one more Widget in the drop-down list. Its name is Sidebar2, and now you need to add something to it.
Summarize the general steps of the second case:
* Apply for a Widgets in functions.php.
* Call sidebar2.php in single.php.
* modify the widgets called in sidebar2.php to the sidebar.
* Drag your widget.
At this point, we have completed the tutorial of displaying different sidebars on different pages!
