Hello!
I'm building out a luxury bed site.
Basically, what I needed to do was on specific bed model pages using a specific template I created, I needed to include the bed brand name before the model name. 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.
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.
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)?
Also, I tried originally to write this as a function called childtheme_override_postheader_posttitle but I couldn't figure out how to get that to work, so I gave up.
Here's what I did:
First function pulled from here: Conditional Tags > WordPress Codex
//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( $post->ID );
foreach($anc as $ancestor) {
if(is_page() && $ancestor == $pid) {
return true;
}
}
if(is_page()&&(is_page($pid)))
return true; // we’re at the page or at a sub page
else
return false; // we’re elsewhere
};Then I wrote in some if statements to check for the page template, and to rewrite posttitles on children of specific pages:
//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't my specific template, to write the normal <h1> title
if (is_single() || is_page() && !is_page_template('products.php')) {
$posttitle = '<h1 class="entry-title">' . get_the_title() . "</h1>\n";
//check if page is using my template, and then is part of one of the brand trees
} elseif (is_page_template('products.php') && is_tree(73) ) {
if (is_page(73)) {
$posttitle = '<h1 class="entry-title"><img src="';
$posttitle .= get_stylesheet_directory_uri();
$posttitle .= '/images/logo-hastens-bk.png" alt="' . get_the_title(73) . '" width="166" height="51" /></h1>';
} else {
$posttitle = '<h1 class="entry-title"><span class="page-ancestor">' . get_the_title(73) . '</span> ' . get_the_title() . "</h1>\n";
}
} elseif (is_page_template('products.php') && is_tree(71)) {
if (is_page(71)) {
$posttitle = '<h1 class="entry-title"><img src="'.get_stylesheet_directory_uri() . '/images/logo-vispring-bk.png" alt="' . get_the_title(71) . '" width="174" height="43" /></h1>';
} else {
$posttitle = '<h1 class="entry-title"><span class="page-ancestor">' . get_the_title(71) . '</span> ' . get_the_title() . "</h1>\n";
}
} elseif (is_404()) {
$posttitle = '<h1 class="entry-title">' . __('Not Found', 'thematic') . "</h1>\n";
} else {
$posttitle = '<h2 class="entry-title"><a href="';
$posttitle .= apply_filters('the_permalink', get_permalink());
$posttitle .= '" title="';
$posttitle .= __('Permalink to ', 'thematic') . the_title_attribute('echo=0');
$posttitle .= '" rel="bookmark">';
$posttitle .= get_the_title();
$posttitle .= "</a></h2>\n";
}
return $posttitle;
} // end postheader_posttitle
add_filter('thematic_postheader_posttitle','product_page_has_brandname');
