Hi geeks,
i am uploading a file to server. Uploading part is working fine. i
am struggle with minor part. actually before uploading file, i am checking
for existance of a file. If it is not exists, directly i am uploading that
file. If it exists, i sud ask user that "This file is exits. Do You really
want to Upload it?"...If YES, i will overwrite it. otherwise, i won't do
anything.
i am using javascript for popup windows. i used confirm()
function(CANCEL / OK).
the problem is, i am not able to get the variable value for php
script. Of course, php is server side programming language & javascript
client side programming language.
Plz see my code & give the solution.
See my progress:
"upload.php"
# Checking for the File existance
if (file_exists($fullPath)) {
echo "<script language='JavaScript'>if(confirm('This
file is already Exists ! Do You Want to Duplicate ?')) { var s=1;} else {var
s=0;} </script>";
$decide="<script
language='JavaScript'>document.write(s)</script>";
echo "$decide";
if (!$decide) {
// Don't Upload
exit;
}
else {
// Upload the file
}
In this code, echo "$decide"; is printing whether 1 or 0. But by using that
variable, i cudn't proceed further. Bcoz it is not useful for manipulating.
* Is anyway to store that variable value in a static file, so that, i can
proceed easily.
* Is it possible to execute shell commands by javascript, so that i can
create file & store this variable.
If it is not possible, plz give any other solution.
Expecting ur reply.
Thanks in advance
Prabhakaran.
