how come i cant pass value from html to perl? And cant print html from perl script?

236 100+
Hi All,

my html code is sno 1) and perl code is sno 2).

a) I tried to print $filename and it cant print out the value, only blank was displayed, and the file could not be uploaded. And it didnt display the html after the perl script executed. Using perl 5.1 and apache 2.2.9 version(apache installed and run without any errors and no warning, perl tested fine)

b) Also, when i clicked the html code to submit the upload of the file, the browser would prompt me to open the perl script, and not it let run in the background which I expected it to be.

Kindly assist!!


Thanks,
Andrew

I'm not sure which tutorial you read, but this is wrong:

Expand|Select|Wrap|Line Numbers
  1. action="/perl/bin/upload.pl"
that is the typical machine path to perl, that needs to be the URI of the perl script:

Expand|Select|Wrap|Line Numbers
  1. action="cgi-bin/upload.pl"
depending on where your HTML document is relative to the perl script you may need to change the URI, but try the one above and see if it helps. Assumes your script is in the cgi-bin, if not change the URI accordingly.

Your perl script looks like it will abort here:

Expand|Select|Wrap|Line Numbers
  1. my ( $name, $path, $extension ) = fileparse ( $filename, '\..*' );
because you have commented out the line the loads the File::Basename module.

Also make sure your apache server is confugured to run CGI scripts. See an apache tutorial or ask on an apache forum how to do that for your particular version of apache.

also make sure you have permission to write and read from:

Expand|Select|Wrap|Line Numbers
  1. my $upload_dir = "d:\uploaded";
also that would be the wrong dir to upload to,
must be at least in your apache website htdocs folder under the upload folder.


according to:

Expand|Select|Wrap|Line Numbers
  1. <img src="/upload/$filename" alt="Photo" />

If your web server is not processing the cgi script correctly, say... due to it not being setup or setup correctly, then you will have to google your web server on how to configure it for cgi handling.

Hi...

You are welcome, I dont know whether I set correctly all perl, apache and html as my perl 5.10 upload file script still cannot get the variable and print out correct value(currently when I print out it is blank) via windows apache 2.2.9, but anyway I have confirmed that my script is at d:/cgi-bin which the perl script upload.pl resides, as I used section d) perl script upload2.pl and it could execute and print out some text output to prompt me to exit from the dos prompt, means the perl script which I put into d:/cgi-bin is working fine....

Been trying for past 2 weeks, very demoralized.... Kindly advise which other parts...

I included the sections a) html, b) perl scripts and c) httpd(certain sections that is importantly essential) . Please kindly see if the perl script or apache httpd config is wrong?

Thanks in Advance!!

Ok, here it is:

Hi Jeff,

Thanks. Ok will take note.

Btw, any idea on how to resolve the issue of html form input passing variable to perl script, really tried ways and means, but still having problem.. I will try code tags in future(not really sure what is meant, but i will use
Expand|Select|Wrap|Line Numbers
  1.  script
to see it you are referring to this. Thanks.

Make use of the available formatting tags in the forum Use CODE tags around your code unless you are posting a single line of code in which case it is acceptable to omit them:
Expand|Select|Wrap|Line Numbers
  1. ..code goes here..
Expand|Select|Wrap|Line Numbers
  1.  ..php code goes here.. 
Expand|Select|Wrap|Line Numbers
  1.  ..C like code goes here.. 
Expand|Select|Wrap|Line Numbers
  1.  ..html code goes here.. 
This will preserve white space and use a mono-spaced font making the code easier to read.

I have confirmed that my script is at d:/cgi-bin which the perl script upload.pl resides
the script should be in the cgi-bin folder that is in the apache folder in the web root folder. Not sure what its all called with your version of apache, but generally something like:

c:/blahblah......apache/htdocs/cgi-bin

and your html file would be in the htdocs folder, which is the web root folder which is localhost (127.0.0.1). Now your version of apache might not be exactly like that so you may need to determine which is the web root folder.

So you start apache, then open a web browser and enter in the address box:

http://localhost/yourpage.html

where yourpage.html is the html document with the form code.

Hi Sir,

Thanks.! I think I got closer, because i placed testing.html under directory
D:\Program Files\Apache Software Foundation\Apache2.2\htdocs

and upload.pl under directory
D:\Program Files\Apache Software Foundation\Apache2.2\cgi-bin

When i type http://127.0.0.1/testing.html, I CAN SEE the html input form NOW :)) THANKS. However, I CANT call the script as the website http automatically pointed to http://127.0.0.1/cgi-bin/upload.pl now.

It gives apache error 403, I checked the folder D:\Program Files\Apache Software Foundation\Apache2.2\cgi-bin again and again it is READ-ONLY :| , although I can copy script into it, I cant run the script as it is read-only(not sure is this the problem, definitely getting nearby, but cant pinpoint exactly where wrong...

Getting closer. Thanks again Sir...

403 means the document can't be found. If the html file is in the htdocs folder and the perl script (upload.pl) is in the cgi-bin folder (that is itself in the htdocs folder) and the action of the form is action="cgi-bin/upload.pl" then I don't know why it is not working. When I check the property of a perl script on my Windows computer its "archive" and the script runs fine. I changed it to read-only and it still worked fine. Are you sure the perl script is in the correct cgi-bin folder? (htdocs/cgi-bin) and the name is upload.pl?

Hi Sir,

Yes, the upload.pl script resides in D:\Program Files\Apache Software Foundation\Apache2.2\cgi-bin. I can show some output using http://127.0.0.1/cgi-bin/upload.pl

However I could not find this directory htdocs/cgi-bin at all... D:\Program Files\Apache Software Foundation\Apache2.2\htdocs is what I found which contains apache default html file index.html and I put testing.html in it which I can link using http://127.0.0.1/testing.html

Any else I needed to set correctly?

1. make sure your .html files are in:

2. make sure your .cgi .pl files are in:

D:\Program Files\Apache Software Foundation\Apache2.2\cgi-bin

3. make sure your action in your html file form is
[HTML]<form action="/cgi-bin/update.pl" method=post>[/HTML]


also for your apache config it sure be

I'm not familair with how Apache 2.2 is setup so maybe there is no htdocs/cgi-bin folder. See Icecracks post.

If you don't know how to start and stop the server you could read those sections. If all you want is to test your perl scripts in a CGI environment, you don't have to read any of the apache documentation.

Hi Kevin,

Thanks for pointing out Icecrack's post on upload dir, I placed this upload directory under D:\Program Files\Apache Software Foundation\Apache2.2\htdocs and when I typed url 127.0.0.1/uploaded/ the directory showed the upload folder out neatly.(wonderful!, one step towards setting up the web)

The httpd config is not changed since the last time I posted, so is the html script(see section a below), but the perl script(see section b) I have changed to below changing the upload directory blackslash to forward slash like in below perl script(not sure if the pathing and directories are correct now?) :

HOWEVER, when I try to upload the files, using upload.pl below, the apache error come out as below :
[Sat Oct 04 03:15:04 2008] [error] [client 127.0.0.1] Premature end of script headers: upload.pl, referer: http://127.0.0.1/testing.html, the webpage result display showed internal server error.

Not if html is wrong or perl script or Even apache is wrong... But I JUST need to pass the variable from html to perl script to print out in dos prompt via apache, it is so frustrating for newbie as I tried various method... Kindly assist.

Hi Kevin,

Thanks. Btw, I used back the old html form and executed your script. Did not work, checked that the script is what you have provided. Maybe variable is not standard, still checking...

http://127.0.0.1/cgi-bin/solid.pl?file=0001.jpg+%5B5%5D&B1=Submit is the url query that the script generated. And the html result printed out is

"Error: Unexpected characters in filename."

Hi Kevin Guru,

I tried out the same html and your script, it works perfectly fine, I think when I download the sample html code below, after the 0001.jpg there are invalid characters [5] before the >file one, and it is affecting the whole script. So therefore after I remove it. It is fine now. The file is downloaded to temp location.


Cheers...
Andrew

Correct html code(need to have file under download directory..
Expand|Select|Wrap|Line Numbers
  1. <html><head> 
  2. <title>Download Page</title>

  4. <body>

Hi Jeff / Adminstrators,

a) I am getting this cant post new post message again... That's why I am using existing posts for this... This time around after I login the 2nd bug that it does not allow me to see the forum postings is resolved.

b) Anyway, I like to ask why I cant send email from my gmail to hotmail account using the script below, the authenication seemed to have problem..(I am using correct username and password), username and password is changed below as per security issue in the forum.. thanks in advance... quite desperate for answer... I got this link http://www.geekzone.co.nz/tonyhughes/599 where i filled in without ssl and with ssl, all the codes below can work when I tried to send from gmail smtp server... but i tried the script from another smtp server, it worked...

Kindly assist with this gmail issue.


Thanks and Best Rgds,
Andrew
