php - set s3 image as a featured image in wordpress post while posting the post programatically from an external source -


i pretty new wordpress. requirement need make post external source using ajax wordpress site. post data merely contain "posttitle,description,etc..." , "imageurl" pre-uploaded amazon s3. i succcessfully able post data using following reference http://codex.wordpress.org/function_reference/wp_insert_post#example

but need save s3 url (external image) worpress post tables , show featured image without again uploading wordpress server.

to figure out how images being saved, logged wp admin , created post featured image, searched wp tables image path , saving image relative path in 'postmeta' table below. enter image description here

the images stored relative reference path.then thought if forcefully insert s3 url (which absolute),wordpress might not able recoginize might searching local files.how achieve inserting s3 urls wordpress tables , make them show in posts. searched everywhere couldn't find solution particular case. appreciated. in advance.

you can use absolute path in guid field in posts table featured image post_type set attachment.

the image set featured given post adding postmeta table post id , featured image post id , meta_key = _thumbnail_id.

insert $wp->post      (post_type, guid, status, post_mime_type)  values      ('attachment', '<imageurl>', 'publish', 'image/jpeg');  insert $wp->postmeta      (meta_value, meta_key, post_id)  values      ('<imagepostid>', '_thumbnail_id', '<postid>');

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
