On the parent brand page, I didn't want the brand name to repeat itself. And then on other pages using the same template (like accessories pages, etc) I didn't want them to try to grab their parent page title.</p> <p>I found a really great function that uses get_post_ancestors to check if a page is a child of another page. I combined that then with rewriting thematic_postheader_posttitle. </p> <p>Was there a better/more efficient way of writing this so that I ONLY had to write the if statements for my custom page templates, vs having to include ALL the cases for everything else (404, is_single, is_page, etc)?</p> <p>Also, I tried originally to write this as a function called <strong>childtheme_override_postheader_posttitle</strong> but I couldn't figure out how to get that to work, so I gave up.</p> <p>Here's what I did:<br /> First function pulled from here: <a href="http://codex.wordpress.org/Conditional_Tags">Conditional Tags &gt; WordPress Codex</a><br /> <pre><code>//function to check if page is child of another page function is_tree($pid) { // $pid = The ID of the page we’re looking for pages underneath global $post; // load details about this page $anc = get_post_ancestors( $post-&gt;ID ); foreach($anc as $ancestor) { if(is_page() &#38;&#38; $ancestor == $pid) { return true; } } if(is_page()&#38;&#38;(is_page($pid))) return true; // we’re at the page or at a sub page else return false; // we’re elsewhere };</code></pre> <p>Then I wrote in some if statements to check for the page template, and to rewrite posttitles on children of specific pages:</p> <pre><code>//update product page titles to include brand name function product_page_has_brandname() { global $post; //Had to check if a page is_page, and then also make sure it isn&#39;t my specific template, to write the normal &lt;h1&gt; title if (is_single() || is_page() &#38;&#38; !is_page_template(&#39;products.php&#39;)) { $posttitle = &#39;&lt;h1 class=&quot;entry-title&quot;&gt;&#39; . get_the_title() . &quot;&lt;/h1&gt;\n&quot;; //check if page is using my template, and then is part of one of the brand trees } elseif (is_page_template(&#39;products.php&#39;) &#38;&#38; is_tree(73) ) { if (is_page(73)) { $posttitle = &#39;&lt;h1 class=&quot;entry-title&quot;&gt;&lt;img src=&quot;&#39;; $posttitle .= get_stylesheet_directory_uri(); $posttitle .= &#39;/images/logo-hastens-bk.png&quot; alt=&quot;&#39; . get_the_title(73) . &#39;&quot; width=&quot;166&quot; height=&quot;51&quot; /&gt;&lt;/h1&gt;&#39;; } else { $posttitle = &#39;&lt;h1 class=&quot;entry-title&quot;&gt;&lt;span class=&quot;page-ancestor&quot;&gt;&#39; . get_the_title(73) . &#39;&lt;/span&gt; &#39; . get_the_title() . &quot;&lt;/h1&gt;\n&quot;; } } elseif (is_page_template(&#39;products.php&#39;) &#38;&#38; is_tree(71)) { if (is_page(71)) { $posttitle = &#39;&lt;h1 class=&quot;entry-title&quot;&gt;&lt;img src=&quot;&#39;.get_stylesheet_directory_uri() . &#39;/images/logo-vispring-bk.png&quot; alt=&quot;&#39; . get_the_title(71) . &#39;&quot; width=&quot;174&quot; height=&quot;43&quot; /&gt;&lt;/h1&gt;&#39;; } else { $posttitle = &#39;&lt;h1 class=&quot;entry-title&quot;&gt;&lt;span class=&quot;page-ancestor&quot;&gt;&#39; . get_the_title(71) . &#39;&lt;/span&gt; &#39; . get_the_title() . &quot;&lt;/h1&gt;\n&quot;; } } elseif (is_404()) { $posttitle = &#39;&lt;h1 class=&quot;entry-title&quot;&gt;&#39; . __(&#39;Not Found&#39;, &#39;thematic&#39;) . &quot;&lt;/h1&gt;\n&quot;; } else { $posttitle = &#39;&lt;h2 class=&quot;entry-title&quot;&gt;&lt;a href=&quot;&#39;; $posttitle .= apply_filters(&#39;the_permalink&#39;, get_permalink()); $posttitle .= &#39;&quot; title=&quot;&#39;; $posttitle .= __(&#39;Permalink to &#39;, &#39;thematic&#39;) . the_title_attribute(&#39;echo=0&#39;); $posttitle .= &#39;&quot; rel=&quot;bookmark&quot;&gt;&#39;; $posttitle .= get_the_title(); $posttitle .= &quot;&lt;/a&gt;&lt;/h2&gt;\n&quot;; } return $posttitle; } // end postheader_posttitle add_filter(&#39;thematic_postheader_posttitle&#39;,&#39;product_page_has_brandname&#39;);</code></pre>
