I've had a personel blog for a while, but one of the things that it lacks is the ability to add comments. So I'm working on a new version of my blog so that one will be able to add comments. I have enough php to retrieve data from the form, but it's when I try to write the data to a file it fails showing "Fatal error: Call to undefined function: file_put_contents() in /home/www/bigtonyc/blog/filewrite.php on line 19"

Here is the form code:

(Toggle Plain Text)

<form method="get"
 action="filewrite.php" name="commentAdd"><textarea
 cols="30" rows="3" name="comment"></textarea>
  <p> <input
 name="page" value="oct1305.html" type="hidden"><input
 value="Submit" name="submit" type="submit"></p>
</form>

and the php:
[php]
<html>
<head>
<title>
Comments page.
</title>
</head>
<body>
Adding comment, will redirect back to original page. If the page does not refresh, please click the link below. 

 
<a href="http://www.bigtonyc.com/blog/index.html">Back</a>
 
 
Comment: <?php echo $_GET["comment"]; ?>. 
Page: <?php echo $_GET["page"]; ?>. 
<?php $filename = $_GET["page"]; ?>
<?php $data = $_GET["comment"]; ?>

<?php file_put_contents($filename, $data); ?>
</body>
</html>
[/php]

You can try it out for yourself if it will help you figure out the error. www.bigtonyc.com/blog/index.html

Thanks for any advice in advance :-). I've never even looked at php before tonight, so i'm really not sure where I'm going wrong.

You might want to check your PHP version, if it's not PHP5 it doesn't have it...

http://www.php.net/fopen

Thanks for the reply, it's not php5, I am going to try out fwrite(), I'll let you know on the results.

Ah it works, here is what I used instead.

[php]
Comment: <?php echo $_GET["comment"]; ?>. 
Page: <?php echo $_GET["page"]; ?>. 
<?php
$filename = $_GET["page"];
$data = $_GET["comment"];
$name = $_GET["name"];
$br = " ";
$brs = " ";

$handle = fopen($filename, "a");
fwrite($handle, $name);
fwrite($handle, $br);
fwrite($handle, $data);
fwrite($handle, $brs);
fclose($handle);
?>
[/php]
