wordpress - How to provide a local fallback for Font Awesome if CDN fails? -


I am trying to develop a Wordpress theme and the CDN fails or I 

 < Code> if ($ CDN_IS_AVAILABLE) {wp_enqueue_style}  
 ('font-awesome', '//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.min.css ', wrong); } Else {wp_enqueue_style ('font-awesome', get_template_directory_uri (). '/css/font-awesome/css/font-awesome.min.css', false, '4.0.3'); }   
 Thanks.   
 
 
 How about this?  
  & lt ;? Php $ test_url = @fopen ('https://netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font-awesome.min.css','r'); If ($ test_url! == incorrect) {// use the CDN function load_external () (wp_enqueue_style ('font-awesome', '//netdna.bootstrapcdn.com/font-awesome/4.0.3/css/font- Use the 'add_action' ('wp_enqueue_scripts', 'load_external');} Else {// local if the URL is not available function load_local () {wp_enqueue_style ('font-awesome', get_template_directory_uri () '/css/font-awesome/css/font-awesome.min.css', false, '4.0.3');} Add_action ('wp_enqueue_scripts', 'load_local');}? & Gt;   
 Additionally, you can add wp_enqueue_script to the function to do this with JP.

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
