warnings (bléééé)...

**rwar** · Oct 25, 2001 05:34

What's wrong with this code? Someone knows what happens here?

Warnings:

Warning: Supplied argument is not a valid File-Handle resource in c:\apache\htdocs\scripts\balhiweb.php on line 33

Warning: Supplied argument is not a valid File-Handle resource in c:\apache\htdocs\scripts\balhiweb.php on line 36

My server is on another machine (same LAN). The user must choose a file and the server should show it (this part is not here). T warnings are in lines:

$file_contents = fread( $filename, filesize( $uploadfilechuva ));

and

fclose( $filename );

PHP Code:


<HTML>

<HEAD>

    <TITLE>BalHiWEB 0.1 :: Mais um produto com a qualidade Embrajara!</TITLE>

</HEAD>

<BODY>



<?php

    if( $submit )

    {

        if (($filename = fopen( $uploadfilechuva, "r" ) == FALSE ))

        {

            print( "Erro ao abrir arquivo!" );

            exit();

        }



        $file_contents = fread( $filename, filesize( $uploadfilechuva ));

        fclose( $filename );

?>



<FORM ACTION="<?php echo($PHP_SELF) ; ?>"

        METHOD=POST ENCTYPE="multipart/form-data">



        <P>Selecione o arquivo de chuvas:<BR>

        <INPUT TYPE=FILE NAME="uploadfilechuva">

        <INPUT TYPE=SUBMIT NAME="submit" VALUE="submeter"></P>

        <INPUT TYPE=HIDDEN NAME=MAX_FILE_SIZE VALUE=1048576>

</FORM>



</BODY>

</HTML>

Thanks for any help.

Ok ,

First close your if($submit) statement:

PHP Code:


                              <?php

                                  if( $submit )

                                  {

                                      if (($filename = fopen( $uploadfilechuva, "r" ) == FALSE ))

                                      {

                                          print( "Erro ao abrir arquivo!" );

                                          exit();

                                      }



                                      $file_contents = fread( $filename, filesize( $uploadfilechuva ));

                                      fclose( $filename );

                               }    

                              ?>

Then let us know what happened.

Espero que tenha ajudado nosso amigo Brasuca!!!

Sorry thats not gonna fix the warnings, the warnings are from the fopen().

This is not the correct way to get a file uploaded through the browser. You should use copy() instead.

http://www.php.net/copy

Thanks for help, stealthen.

I missed to put a } in the end of the code. It's there. I changed a line of the code. It was a parenthesis in a wrong place.

PHP Code:


if (($descriptor = fopen( $filename, "r" )) == FALSE )

Now I have just one warning:

Warning: 1 is not a valid File-Handle resource in c:\apache\htdocs\scripts\balhiweb.php on line 36

I really don't know the '1' is from. A php code?

PHP Code:


$file_contents = fread( $descriptor, filesize( $filename ));

Is a parenthesis missing?

OFF-TOPIC: Where are you from, stealthen? Brasil, I suppose... Which part...

**freddydoesphp** · Oct 25, 2001 11:28

Hello? Are you listening. If you are trying to upload a file from the browser YOU ARE GOING ABOUT IT THE WRONG WAY. See my post above.

**stealthen** · Oct 25, 2001 11:40

Well It seems like freddydoesphp knows already what is wrong. So try to use copy()

Off-Topic -> rwar send me an e-mail I got go off line now.

Take it easy, man. I was just posting the reply (see h:m:s).

Thanks, freddydoesphp. I'll try that.

Could you give an example on how a <INPUT TYPE=FILE> work with copy?

Thanks since now.

you need to use copy() on the uploaded file to copy it to your webserver (as php stores and uploaded file as a temp file that isn't usable yet until you use copy) before you can use the file functions on it.
read about it at the link freddy posted above.

though i'd recommend renaming the file as there's a pretty good chance of getting duplicate filenames.

**rwar** · Oct 26, 2001 11:13

Could you (anyone) write an example? Or write where I can look for one?

I really didn't understand how it works.

Thanks.

PHP Code:


<?

$ext = ".jpg"; // this is where you put the file extension.

$path_to = "/path/to/store/file".$uploadfilechuva;

if(copy($uploadfilechuva, $path_to.'$ext'))

{

  echo "Hey! It worked!";

}

else

{

  echo "Aw man! It didn't work!";

}

?>
