html - Can I change the value of PHP variables in CSS hover selection? -

-

I have a problem using CSS and PHP.
Here is the code: 

  .book {width: 100px; Height: 50px; Background-image: url (out2.png); Status: Completed; Left: 557px; Top: 70px; }. Book: hover & gt; .right {Visibility: visible; Opacity: 1; Transition delay: 0; & Lt ;? Php $ pos = 1? & Gt; } .right {width: 300px; Height: 200 pixels; Background-image: url (r2.png); Status: Completed; Left: 100px; Top: -50px; Visibility: hidden; Opacity: 0; Transition: Visibility 0 S. Linear 0.2 s, Opacity 0.2 S. Linear; }

I have to change the value of variable $ pos to 1 when users will move their mouse over the mouse.

but $ pos is always 1 is not a place where my mouse is.

Do I use the wrong way to design this website?

I think you have two options to change the value with a javascript and then it's ajax Submit with The second is to change the value with javascript in a hidden field and then submit it with the form.

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
