php if else is_page… need some help

Exactly what do you mean by “breaks it”? Does it just not show up, or does it show fatal errors, warnings, or something else?

Without knowing anything more… from your small description there I am going to guess that “105” is a category archive listing? Is this a page with a shortcode on it or is it an actual archive page?

Sorry.. the page with is 89 still shows the sidebar correctly as its coded above, but when i add the code for page 105, the sidebar content for page 105 does not show at all (89 still shows).

They are both actual pages. 105 is querying a category of posts via a panel in my interface (It is a theme from themify.me, and they give you an option to query certain categories within the page)

And here is my entire sidebar.php page

<aside id="sidebar">
	<div style="height:120px">?</div>
	<input type="text" onblur="if (this.value == '') {this.value = 'Search...';}" onfocus="if (this.value == 'Search...') {this.value = '';}" id="s" name="s" value="Search...">
	<div style="height:5px">?</div>

	<?php if( is_page('89') ):?>

</aside>

I’d try adding in some (temporary) debugging code like:

<p>This page ID is '<?php echo $post->ID; ?>' and this is a '<?php echo get_post_type ($post->ID); ?>'</p>

This will tell you the page ID and the post-type, which should be “page”.

Seeing as how this is done through a theme’s back end it’s possible that it’s not being seen as a “page” type, so it’s worth checking.

check, if that page 105 is using a page template with custom query, that the query loop is terminated properly with wp_reset_postdata() or wp_reset_query()
