Handling $_POST in Wordpress -


how can handle $_post in wordpress? creating custom "send" button displays in plugin's admin panel. when pressing "send" button, mails have send subscribers. how can done? how can handle custom "send" $_post button?

i have tried init, no succes:

add_action('manage_nieuwsbrief_posts_custom_column', 'nwsbrf_custom_nieuwsbrief_column', 10, 2);  function nwsbrf_custom_nieuwsbrief_column($column, $post_id) {  global $wpdb;  $getcategories = $wpdb->get_results( $wpdb->prepare("select * wp_nwsbrf_couple inner join wp_nwsbrf_categories wp_nwsbrf_couple.category_id = wp_nwsbrf_categories.category_id , id = %d", $post_id) );  foreach ($getcategories $categorie) {      switch ($column) {         case 'cat':         echo $categorie->category_name;     break;     } }     switch ($column){         case 'send';         echo '<input type="submit" class="button button-secondary button-small" name="send_post" value="verzenden">';     break;  } }  add_action('init', 'process_send_post');  function process_send_post(){  if($_post['send_post']) {      echo 'postelijk';    }  }

you looking isset() function in php:

if(isset($_post['send_post'])) {     // handle form }

in code, try not use switch single cases, use if instead, makes code more readable , compact.

also can category of post using built-in wordpress function get_the_category($id). no need execute db query yourself

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
