<?php      $valid_formats = array("jpg", "png", "gif", "bmp");     if(isset($_post['submit']))         {             $name = $_files['photoimg']['name'];             $size = $_files['photoimg']['size'];             if(strlen($name))                 {                     list($txt, $ext) = explode(".", $name);                     if(in_array($ext,$valid_formats) && $size<(1024*1024))                         {                             $actual_image_name = time().substr($txt, 5).".".$ext;                             $tmp = $_files['photoimg']['tmp_name'];                             if(move_uploaded_file($tmp, $path.$actual_image_name))                                 {                                     $image="<img src='uploads/".$actual_image_name."' id=\"photo\" style='max-width:500px' >";                                  }                             else                                 echo "failed";                         }                     else                         echo "invalid file formats..!";                                  }             else                 echo "please select image..!";         } ?>

while submitting form, page getting refreshed. want without page refresh.

suppose if put above php code in php function, without using
if(isset($_post['submit']))

then, there way, call php function using ajax.

thanks in advance....

actually, looking can submit php form via ajax image selected , upload image. found code,

$('#photoimg').live('change', function(){       $("#preview").html('');      $("#imageform").ajaxform({         target: '#preview'     }).submit();     });

here, photoimg id of input type file, imageform id of form, , preview id of div, preview going displayed. when file selected, change event fired , form submitted. can refer this.

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 ...
