Number 1 is not wordPress, but PHP. $_GET['type']
is undefined. Use an isset( $_GET['type'] )
conditional.
Number 2 the error message tells you exactly what to do. Instead of calling:
add_custom_background();
…call:
add_theme_support( 'custom-background' );
Number 3 the error message tells you exactly what to do. Instead of calling:
attribute_escape();
…call:
esc_attr();
Number 4 is telling you that you’re trying to get the property of an object that isn’t set. In this yes, that object is $post
, which needs to be globalized before you use it. Instead of this:
$excerpt = $excerpt.'<a class="read-more" <a href="'. get_permalink($post->ID) . '">Read more »»</a>';
…do this:
global $post;
$excerpt = $excerpt.'<a class="read-more" <a href="'. get_permalink($post->ID) . '">Read more »»</a>';
