PHP Create Download Link - 


<?php     $file = sevence_data_root."/resource/devdemo/promo_card.tiff";     header('content-description: file transfer');     header('content-type: application/tiff');     header("content-type: application/force-download");// browsers need     header("content-disposition: attachment; filename=promo_card.tiff");     header('expires: 0');     header('cache-control: must-revalidate, post-check=0, pre-check=0');     header('pragma: public');     header('content-length: ' . filesize($file));     ob_clean();     flush();     readfile($file);     exit; ?>

my issue download image can't viewed. can me issue?

content-type: application/force-download");// browsers need

no browser need this. it's dirty glitch..

reasons why file cannot opened:

  1. you have space or invisible characters @ beginning of script

  2. the path loading file might wrong , doesn't read (what size downloaded file?)

  3. the file corrupt

  4. you don't have tiff-viewer

the correct mime type image/tiff (instead of application/tiff)

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
