[PHP] Passing JAVASCRIPT variable to PHP Script...

[Captain]

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.

[PHP] POPUP window in PHP

[Captain]

hi,
i want to do YES/NO confirmation (like POPUP). If YES, it will upload a file
into server. Otherwise, it won't do anything.
In JavaScript, i can get using confirm(); But i am not able to do
manipulation from that javascript variable.

My Code(partial):

?
if (file_exists($fullPath)) {
echo ;
   $decide=??php;

# It is Printing either 0 or 1. But I can't able to manipulate further. For
eg, i can't do like the following,   

   if ($decide) {
   // Upload
   } else {
   // Don't Upload
   }
}

Please help me reg this..Please provide some solution for this..Thanks in
advance.

Re: [PHP] POPUP window in PHP

[Captain]

hi dude,
actually, i am new to php. i am not understanding clearly. plz explain it
clearly. 
My requirement is, i want to upload one file. i am checking whether it
exists or not in Server side.
If it exists, i am popping up a window that Do u want to have Duplication
of this file?.If YES, i sud upload. otherwise i sud giveup.
In script update part if once u uploaded one script from your PC (client)
and after some time u r editing or making change to the file(client). and
wish to put into that then it will ask for duplicate. that part you need to
think. 

Please reply to me.
Thanks again.

 PHP is server-side, not client-side. You can have the confirmation 
 passed as a GET variable in a two-step process for example, i.e. first 
 show a confirmation form if $_GET[confirm] is not set, else check 
 $_GET[confirm] and process the uploaded file.

[PHP] preg_replace problem

[The Captain]

I have a regular expression that's not giving me the results i really need.

I have a bunch of strings coming at me that need to be truncated if they're
over 15 characters... but not to truncate until after it reaches the first
word.

This regular expression just doesn't seem to want to work 100%:

$myString = preg_replace("/.{15}\w)?\s.*/","\\1",$myString);


This will turn:

'PROJECT - Marketing Pitch'

into

'PROJECT - Marketing\1'


However... when i change it to:  /(.{15}\w)+.*/
everything seems to work fine.
I can't really use this regex though, because it will keep matching that 15
character word until it reaches the end.  I need it to stop matching after
it finds the first match (if it needs to match at all).

In perl:
+ - means match 1 or many times
* - means match 0 or many times
? - means match 0 or 1 time

Could someone help me see my error... i'm driving myself bananas trying to
find it.  Perhaps pcre in PHP doesn't support the ? in the regular
expressions.

Best Regards,
Rob
