I want to manipulate the html-title tag, so <title> these not the content of the title-tag!
I use child-themes and it's inevitable, because the template have to be easy to update. So I have to use the functions.php or the header.php in the child-folder.
At moment I try it with the functions.php
At moment I have following situation:
<!-- Start WP_HEAD
================================================== -->
<!-- This site is optimized with the Yoast WordPress SEO plugin v1.5.3.3 - https://yoast.com/wordpress/plugins/seo/ -->
<title>My awesome title-content</title>
<meta name="robots" content="noindex,follow,noodp,noydir"/>
<link rel="canonical" href="WEBSITE" />
<meta property="og:locale" content="de_DE" />
and I want to have these situation:
The focus are on the title-tag
<!-- Start WP_HEAD
================================================== -->
<!-- This site is optimized with the Yoast WordPress SEO plugin v1.5.3.3 - https://yoast.com/wordpress/plugins/seo/ -->
<title itemprop="name" id="company_name">My awesome title-content</title>
<meta name="robots" content="noindex,follow,noodp,noydir"/>
<link rel="canonical" href="WEBSITE" />
<meta property="og:locale" content="de_DE" />
my current try in the functions.php in the child-folder are:
add_action('get_header', 'blog_template_add_ob_start');
add_action('wp_head', 'blog_template_add_ob_end_flush', 100);
function blog_template_add_ob_start() {
ob_start('blog_template_add_filter_wp_head_output');
}
function blog_template_add_ob_end_flush() {
ob_end_flush();
}
function blog_template_add_filter_wp_head_output($output) {
if (is_single()) {
$output = preg_replace('/<title>(.*?) - (.*?)<\/title>/', '<title><span itemprop="name" id="company_name">$2</span> » $1</title>', $output);
#$output = str_ireplace('<meta property="og:url" content="' . $url . '" />', '<meta property="og:url" content="' . esc_attr(esc_url($altUrl)) . '" />', $output);
}
return $output;
}
my first try was these: first:
function add_itempromp_to_title( $str )
{
#$str = preg_replace('/<title>(.*?) - (.*?)<\/title>/', '<title><span itemprop="name" id="company_name">$2</span> » $1</title>', $str);
return $str;
}
add_filter( 'wp_head', 'add_itempromp_to_title', 99 );
I had try these: Manipulating wp_head contentManipulating wp_head content but isn't work anymore.
Does anyone have an idea?
