php - Internal 500 error on ajax post -


i trying post on our ajax request update user meta (this not wordpress related question). way is, use jquery draggable ui .position retrieve position.top number, @ stop() called function posts value ajax file. reason returns 500 internal error , makes our ajax file inactive other functions.

this first step $(document).ready(function() {

                $(".top_image_roll").hide();              $(".five img").draggable({                 axis: "y",                 // find original position of dragged image.                 start: function(event, ui) {                      // show start dragged position of image.                     var startpos = $(this).position();                 },                  // find position image dropped.                 stop: function(event, ui) {                      // show dropped position.                     var stoppos = $(this).position();                     update_image_coords_1(stoppos.top);                  }             });             });             </script>         <?php } else { ?>                    <?php }?>

this function

function update_image_coords_1(coordss) {    $.post('http://xxx/xxx/xxx/xxx/ajax.php',     {       'action': 'update_image_coords_1',       'coords': coordss,       'user_id': '<?php echo $user_id; ?>'      }   ); }

and on ajax file

if( !empty($_request['action']) && $_request['action'] == 'update_image_coords_1' && !empty($_request['user_id']) && !empty($_request['coords'])) {  $coords = $_request['coords']; update_user_meta($_request['user_id'], 'update_image_coords_1', $coords);  die(); }

is there doing wrong? other suggestions? in advance

your if statement missing couple of closing brackets after empty calls:

if( !empty( $_request['action']) && $_request['action'] == 'update_image_coords_1' && !empty($_request['user_id'] && !empty($_request['coords']) {

should be:

if( !empty( $_request['action']) && $_request['action'] == 'update_image_coords_1' && !empty($_request['user_id']) && !empty($_request['coords'])) {

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
