Files and PHP

I was wondering how I might create a file using a PHP form action? I searched PHP.net but I didn't see any function to create a file. Thanks

Searching with your eyes fopen usually works better

http://us3.php.net/manual/en/function.fopen.php

:)

Well, fopen wouldn't seem to create, but thanks anyways

Okay, so my meager quest to create a file creation system So I don't have to be at home to add files. My error is this

Warning: fopen("", "x") - No error in c:\ibserver\www\fcreate\filecreater.php on line 4

Warning: fwrite(): supplied argument is not a valid File-Handle resource in c:\ibserver\www\fcreate\filecreater.php on line 7

and then my form action
<?php
$filename = $_POST['filename'];
$filecontents = $_POST['filecontent'];
$open = fopen($filename,"x");
$chmod = chmod($filename, 0777);
if (is_writable($filename)) {
fwrite($filename,$filecontents);
echo "$filename sucessfully created";
}
else {
echo "<B>Error:</b> Cannot write to file";
}
?>


I know there are probably many things wrong. Any help anyone?

Thanks

That says it all.

$filename = $_POST['filename'];

Isn't being set. Read the errors.

Okay, I uploaded it to the web http://www.net-riches.com/includes/fcreate/

Try for yourself, I get different errors now. Still using same code as above.

Do you have multipart set in your form attribute???

Can you show us the html?

Have you chmodded the directory the file's to be created in?

bcarl314, the html is on the page he showed ( http://www.net-riches.com/includes/fcreate/ )

I don't believe I had, but where are the files going to be created in? The folder that the script is in?

Thanks for your continued help

Are you blind or just South Carolinian? :D



'x' Create and open for writing only; place the file pointer at the beginning of the file. If the file already exists, the fopen() call will fail by returning FALSE and generating an error of level E_WARNING. If the file does not exist, attempt to create it. This is equivalent to specifying O_EXCL|O_CREAT flags for the underlying open(2) system call. This option is supported in PHP 4.3.2 and later, and only works for local files.

D'OH <slaps what="head">

Ok, in that case, change your <form> tag as below


<form method="POST" enctype="multipart/form-data" action="filecreater.php">

Is PHP 4.3.2 installed on your host? That's needed as a minimum requirement if you want to use the 'x' flags. Why don't you go with the standard 'w' argument?


Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.

Yes, I have 4.2.3 on my server. I changed it to "w". Now it is creating the file, but nothing is being written to the file. I still get one error, which I think is the reason the file is not being written -

Warning: fwrite(): supplied argument is not a valid File-Handle resource in /usr/local/psa/home/vhosts/net-riches.com/httpdocs/includes/fcreate/filecreater.php on line 7

Thanks again for the continued help :D

Assuming you use a similar code as shown above, you need to pass the file handle as an argument to frwrite(), not the file name itself. Basically this example illustrates the usage:


$fp = fopen('foo.bar', 'w');
fwrite($fp, "hello foo");
fclose($fp);

Wonderful guys! It creates and writes to the file now. Step 1 complete. Now, when I acess the file I created, example http://www.net-riches.com/includes/fcreate/testone.php i get the errors as you can see. I typed in testone.php for the file name and <?php
echo "TEST";
?> for the file contents. It is adding slashes to the " "'s. How do I stop it from doing that?

Before you do anything else, secure the form immediately from general access! Right now everybody can create arbitrary PHP files on your server. You can also delete the info.php file I just created... it was just a test, nothing terrible inside it. ;)

Should I .htaccess it?

btw, I changed the path to the file for my safety. so the links in previous replies will be 404's
