How to Conditionally Display WordPress Sidebar Content with is_page
In a non-widgetized sidebar you may have content that you only want to show on certain pages but not on others. I started thinking about this after my (Anti) Social WordPress Spring Cleaning article where Ajith mentioned that on my portfolio page I was duplicating the testimonials. I had the testimonials listed with each project and in the sidebar.
So, I decided to use conditional code to only display the sidebar testimonials on particular pages. This part of my site uses a different sidebar than the blog. You can see the testimonials on the About, Services or Contact pages but not on the Portfolio page.
Here is the code I use to do this. It’s conditional code – if this do this, if not do something else – that checks to see what page is being displayed. It shows the testimonials or it doesn’t.
<?php
if (is_page(array('contact','about','services'))) { ;?>
list of testimonials here
<?php } ?>
The is_page (array … is checking to see for the three pages listed and shows the testimonials, if we are on one of those pages. You can use the page name or the page ID in the code.
If I wanted to show something in place of the testimonials I would include the else code.
<?php
if (is_page(array('contact','about','services'))) { ;?>
list of testimonials here
<?php } else { ?>
alternative code here
<?php } ?>
That’s really all there is to it. You can read more about WordPress conditional tags in the codex. The more time I spend reading this part of the codex the more it starts to make sense to me.

Hi Rick – Thanks! I try to explain it so everyone can understand. So many articles I find assume a certain level of knowledge and they can be hard to follow.

so this code can be used on any php page? not just wordpress? i have an option to add my own php code to a section in my forum, but i don’t know what code could go there. i guess the above would be an example. i can fool around a little in php, but i really don’t understand it. i have wondered though what code i could possible use for that section. hmm, maybe i’ll go play and see what happens.
this comment might not make sense but i think you helped me understand something a little better. :)

Hi Natural – The code is WordPress specific. WordPress uses a modified version of PHP.
In PHP you might want to look at file_get_contents or file_exists.
What do you want to display in the code block? That would help determine what php code to use. I know a little.

April 13, 2009 at 4:32 pm
Kim, thanks for this tip! There are a couple of pages that I don’t want sidebars on, and I think this will do the trick. Now all I have to do is to translate it to Thesis-speak!

Hi Mike – Well, I kind of answered you on Twitter but in at least version 1.3 + of Thesis you can use the No Sidebars template on a page by page basis.
I suppose you could wrap the entire sidebar in is_page but then I think you would have a big empty white space. Regardless, it’s still a useful piece of code.
Thanks for the retweet. :-)

So this has nothing to do with widget-ready themes?

Hi Dennis,
It won’t work wrapped around a widget but it can still be used with a widget ready sidebar, if the sidebar also includes code. For example, the top part of the sidebar on this page contains code but where it splits into two parts is widgetized.
April 13, 2009 at 7:00 pm
Cool I think mines the same way.

oh well then never mind. if it’s WP specific. i’m not sure what i want to add in the block. i just have the OPTION of adding some php code to display something. i’m not sure what code i would want to display…but i understand the scenario.

Thank you for sharing this. Just the other day, I thought about doing different sidebar items for different pages. Or actually, different categories, so if a post of mine were in photography, it would show photography interest links, and so on. I’m guessing that kind of thing could be done, assuming my posts were only marked in one category.

Hi Kristi – I can’t believe I missed your comment. I even remember thinking about it and starting to reply … geesh.
It would be easier if the posts were only in one category but I don’t think they would have to be. Take a look at in_category rather than is_page – I think that would do what you need.

pefectly simple explanation of a very useful feature. I remember when wordpress designer had his articles about it, was not as easy to understand as this. Good job :)

Hi – Thanks! My goal was to make it easy to understand and it seems that I have succeeded.
April 14, 2009 at 9:00 pm
Yes, you can do many things with word press which is very flexible.
I am using similar hack to show different sidebars for different category , on anther blog I am using different sidebar according to the authors.
anybody wants me to share it?

Didn’t work for me. I tried to show an empty sidebar on one of the pages. Instead – it showed the contents of the FOOTER. I have no idea how this could happen.

Thanks for the code. I’ve been trying to find a plugin that does exactly this as I’m a quite a lazy coder. Why re-invent the wheel? Well anyway, no plugin found but I have found your page with an explanation of this. Implemented it and voilla! It works. Thanks once again.

Hi Diego – Great! I’ve struggled with these things to – as soon as I get something to work I write it up in a way that is understandable – as an article I wish I had found when I was struggling.
January 19, 2010 at 7:26 am
Great, but, what if i want that for certain url, and only that.?
ie. http://www.example.com/page1.html
That page use the same template and it’s a php page
January 19, 2010 at 8:47 am
Hi Daniel – If you only want it for one page that you use is_page without the array.
is_page(‘services’) or whatever the name of the page is.
September 27, 2010 at 4:07 am
Can we use the same code for post?? and also.. you have not mentioned where to use this code?? in page.php or post.php if i want to try with post.. and also.. is there any plugin to manage this stuff.. Just curious to know the answers of it.. Thanks for the article. It gave much information on the same time it raised this many question. I will be thankful, if you answer my query.
Chintal´s last post ..So- you think you get right traffic to your site
September 27, 2010 at 9:02 am
I used the code in the sidebar. You can use the same code for a post as a second loop. You would need to edit the template file where you wanted this to be located.
There is a plugin called Widget Logic that might be useful to you. You create your widgets and then with Widget Logic can set which pages they appear on.
http://wordpress.org/extend/plugins/widget-logic/
I don’t know of a plugin that will add conditional code to a post or page.
September 27, 2010 at 9:22 am
Thanks for the information. After i read your article, i was researching more on internet and I found this wonderful plugin. I hope this will benefit readers like me reading this post in near future. This plugin let you create multiple sidebar and then we can assign post/page to it.

Thanks once again. I was searching such plugin for the past few weeks. And only after reading your article. I got the basic keywords which did the magic.

November 15, 2010 at 5:46 pm
I’ve got this partially working in test environment on my server behind firewall. problem is I’m trying to use the home page as the variable page. If the showing the home page, I want to display a specific graphic in the header. If not showing, then I don’t want to display any image.
I can get this to work on other pages, but not the home page, because it is the landing page and doesn’t display a page name in the url. It is simply
http://www.example.com
It doesn’t say example.com/home
BTW, great tutorial. I wonder why more blogs don’t use this it’s such a great way to customize a wordpress site.
November 15, 2010 at 6:24 pm
Hi Keith
Use is_home instead of is_page
http://codex.wordpress.org/Function_Reference/is_home
November 16, 2010 at 1:27 pm
Thanks Kim! I couldn’t get “is_home” to work for me, but you got me going down the right path. This is how I ended up solving it:
It works on my test platform, but I haven’t tested it across browsers. Mac only now.

Great Article – Thanks!
This plugin that I just wrote also enables you to publish content in your sidebar that is specific to the current post or page being displayed.

Another suggestion – The Graceful Sidebar Plugin creates a widget that enables you to use custom fields in a post or page that display in the sidebar. You can use it to display custom html or a simple message. Enjoy!
December 17, 2010 at 7:42 am
Thanks Mike – I’m definitely going to try it out.

Can you put more php if statements after the “else” argument?
Sincerely,

February 15, 2011 at 9:01 am
Hi Matt,
Yes, you can but you would want to use elseif rather than else.
There are examples on this page starting with snippet 3

Works perfectly! I’d been searching for a way to do this when I finally found your page by Googling “wordpress is_page sidebar.” Thank you!
