wordpress - How to use get_posts() and form select -

-

hi i'm new wp plugin development. far, i'm doing except form select piece seems kicking head. i'm trying show list of recent post in select field admin select , stuff title not show. tried in radio button , text field , got no result. please, missing in form?

<form method="post"><select name="article"> $args = array( 'numberposts' => 10, 'order'=> 'asc', 'orderby' => 'title' ); $postslist = get_posts( $args );     foreach ($postslist $post) : setup_postdata($post);  echo'<option value='".the_id()."'>'".the_title()."'</option>'; endforeach; echo"</select></form>";

i can't test right now, there couple of possibilities.

first, the_id() echo value - won't work you'd in middle of concatenation. need get_the_id() instead.

second, matching of quotes seems odd when you're echoing option. assuming want output like

<option value="1">title</option>

your echo should 

echo '<option value="' . get_the_id() . '">' . get_the_title() . '</option>';

c++ - Using OpenSSL in a multi-threaded application -

-
i have been writing soap client application in c++ on ubuntu using openssl https transport , pthreads threading. have number of threads - 1 central data acquisition thread periodically gets worker threads make soap requests via shared mutex protected queues. reading documentation openssl found is openssl thread-safe? in openssl faq describes mechanisms required ensure thread safety when using openssl. implemented , works fine. the reason question conceptual difficulty really. thinking implementing same functionality application has already, instead of using threads, create 2 seperate applications : 1 worker thread (of multiple copies running) , main data acquisition thread. use tcp sockets communicate between 2 rather mutex protected queues. may bad idea not important - confusing me would have implement same functions required ensure openssl thread safety in second approach or not? my guess not have , treated independent (indeed surely must many applications use openssl) re...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
