If you wanted to use your switch statement, you could use:
switch ($post->post_name){
case 'home':
$content="How much money....";
break;
case 'about':
$content="We design....";
break;
case 'services':
$content="At the....";
break;
case 'blog':
$content="Find out whats....";
break;
case 'portfolio':
$content="Unique, Beautiful....";
break;
case 'contact':
$content="Get in touch to....";
break;
case 'privacy-policy':
$content="How much money....";
break;
case 'terms-and-conditions':
$content="How much....";
break;
}
echo '<div class="strapline strap">'.$content.'</div>';
First. I would follow @rrikesh approach of using if/else and use is_page() correctly.
But this code is really inefficient. If you can do an “is_page()” test, then you are on the page, and have access to it’s content. Personally, I would add a custom field to the pages to hold $content. Then on the pages, you can simply call the custom field
$content = get_post_meta($post->ID, 'content', true);
echo '<div class="strapline strap">'.$content.'</div>';
You can use a free plugin like Advanced Custom Fields to quickly add a custom meta field to your pages and your content is easier to organize and edit later.
