How To: Use Conditional Tags In Thesis

So you want to use WordPress Conditional Tags (or statements) in your Thesis customization. No sweat! Here is a basic example of how to make stuff show up ONLY where you want it; using Thesis OpenHook

EXAMPLE CODE

<?php if (is_front_page()) { ?>
this is the homepage

<?php } else if (is_single()) { ?>
this is a post

<?php } else { ?>
this is a page
<?php } ?>

What does all that mean?

1. If I’m on the homepage, write “this is the homepage”

2. Or if I’m on a post, write “this is a post”

3. Unless I’m on a page then write, “this is a page”

It doesn’t get any simpler.

You can post the above code into any hook in Thesis OpenHook (just remember to tick “Execute PHP”)

and it will show

Let’s say you wanted Featured Content Gallery to show up on the homepage and pages only. The syntax would look like this:

<?php if (is_front_page()) { ?>
<?php global $post; include(WP_CONTENT_DIR . '/plugins/featured-content-gallery/gallery.php'); ?>

<?php } else if (is_single()) { ?>

<?php } else { ?>
<?php global $post; include(WP_CONTENT_DIR . '/plugins/featured-content-gallery/gallery.php'); ?>
<?php } ?>

Notice the blank space below is_single()) That says, “If this is a post, do nothing”.

Can you please tell me how I would exclude code on certain pages, ie the “legal” pages? I’m not real good yet on writing the code, so could you please give me the code that I would use? I only want the openhook code to show on all single posts and pages with the exception of About, Contact, Privacy Policy and Disclosure pages.
I have to fix this ASAP!
Thank you.

  Did you check “Execute PHP on this hook”?

Hey Greg,
This actually got me going on Thesis today…I am using Openhook and just started with the theme today and this was a huge help in getting conditionals to work in Openhook, which, as you pointed out, uses a different syntax then having to use custom_functions.php/
Thanks for getting me out of the gate with Thesis and Openhook.

Question, what if I wanted to basically just have a text appear on the home page only..using Thesis Hooks? Is that possible? For example, say I wanted to say Welcome on the top of the home page, but not on other pages. Can I use Thesis Hooks to accomplish this? Thank you for this useful info by the way.

Hello! Your tutorials have been a HUGE help for me thus far! I do, however, have one problem. I was able to get the Featured Content Gallery slider on my blog using the Thesis Open Hook code from your other post. However, the slider was showing up on all of my pages, when I only want it to show up on my home page. When I implemented your code above, it replaced ALL of my pages with the home page (i.e. my “About” page, “Blog Roll” page, “Recipes” page and “What’s In Season” page all were replaced with the front page). I definitely didn’t want this but do want the slider to stay only on my home page. Any suggestions? I’ve left my site with the slider on each page since I didn’t want all my pages to look like my home page. Thanks so much!

Would you happen to know how to write this to change a css class on a specific page? Say, if you’re on the page called blog, switch div id=”header” to div id=”header-blog”? I need to change the header image on that page only. Any help would be greatly appreciated!

  You would use conditional tags in custom_functions.php to call a new stylesheet. For example here is what I do:
```
// Build Conditional CSS
function single_back() {
if (is_page('966')){
?>
<link rel="stylesheet" href="<?php bloginfo('template_url');?>/custom/single.css" type="text/css" media="screen, projection" />
<?php } }
add_action('wp_head', 'single_back');
```

Few people use the is_front_page() – should be used more!

Which rather neatly answers my question on another article about placing the Featured Content Gallery on the home page — and teaches me how to handle similar stuff in the future. Thanks!
