Hello:
I have the following code in a PHP file. An HTML form passes user
comment data to the PHP, which then appends the user comments to the
end of the HTML file on which the form is located. This PHP code
works: the HTML file with added comments displays correctly in my
browser. However, appending text to the very end of the HTML file
creates what is, strictly speaking, invalid code.
I am looking for a way to tell PHP to write data to the file JUST
BEFORE the </bodytag. I have read about fseek(), but don't know for
sure if the number of characters (or HTML tags) after my "user
comments" section is going to remain constant.
Being extremely new to PHP, all I know is that I need to move the file
pointer backwards from the end of the HTML file until just before </
body>. I would appreciate any help in doing this.
<HTML>
<HEAD></HEAD>
<BODY>
<?
$name = $_POST['name'];
$website = $_POST['website'];
$message = $_POST['message'];
$timestamp = $_POST['timestamp'];
$fp = fopen(basename( $_SERVER[HTTP_REFERER]), 'a');
if (!$fp)
{
echo "There was an error. Please try again later.";
exit;
}
else
{
$outputstring = "<hr>" .$timestamp. "<br>" .$name. "<br>" .$message.
";
fwrite($fp, $outputstring, strlen($outputs tring));
fclose($fp);
echo "<BR>Commen t posted successfully.<B R>Click <a href='next'>her e</
Ato continue.";
}
?>
</BODY>
</HTML>
