php - Replace uploaded document on confirm not working -


my requirement follows: when user uploads file should check "file exists", if file exists must show confirm box if 'ok' have replace , if cancel reverse. following code

if (file_exists($path . $documentname)) {                 $msg = $documentname . " exists. ";                 ?>                 <script type="text/javascript">                     var res = confirm('file exists want replace?');                     if (res == false) {                 <?php                 $msg = 'file upload cancelled';                 ?>                     } else {                   <?php                 if (move_uploaded_file($_files["document"]["tmp_name"], $path . $documentname)) {                     $msg = $documentname . " file replaced successfully";                     $successurl = $document_path . $documentname;                 }                 else                     $msg = $documentname . "upload failed";                 ?>                     }                 </script>";                 <?             }

my problem if give cancel file getting replaced. let me know i'm wrong or there other approach? please me close issue note:jquery not allowed.

your problem mix javascript , php. php-code run on server , generates html-document. @ point, file gets replaced already.

then, document (with javascript-code inside) send user , there javascript-code run. , in moment, user gets see confirmaion-dialog, though file replaced!

take @ source-code php-code generating , see mean.

a solution add checkbox confirm overwriting files. after hitting upload-/submit-button, php-script check if box checked , either replace file or not.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
