Working with a file - appending to html

rastem

Hey all,

I'm sure there's an easy answer to this, but I have not found one. I need to append links to an html file, but am not sure how to do it. I have worked in php, but never with the file functions (fgets, etc.) so I'm a bit lost. The idea is to go to the end of the page, just before the </body> tag, and input in a new link, say <a href='www.link.com'>Title: Link</a>. Save the new file then close it. Please post some help, and sorry if it seems very newbie!

You'll first need to open a file pointer using [man]fopen[/man]. Then, use [man]fread[/man] to grab the contents into a variable. You might call [man]fclose[/man] then.

From there, it's up to your knowledge of strings. Add your link however you decide to do so.

Once your have the new data in a variable, go through the steps outlined above again, using [man]fwrite()[/man] in place of the [man]fread[/man] above....

Good luck! 🙂

P.S. To tell truth, you could probably leave the file open while you insert the link and shorten the coding a little....

This code works where the code is formated so that the end body tag is the first thing on a new line. You could do some more string checking in order to improve this:

<?php
$file = "test.html";
$handle = fopen($file, 'r+');

$body = "</body>";
$fileinfo = "";
while (!feof ($handle))
{
        $line = fgets($handle);
        if(!(strpos($line, $body) === false))
        {
                //found the end bodytag
                $filecontent = "<a href=\"hello.html\">Hello</a>\n";
                $fileinfo .= $filecontent;
        }
        $fileinfo .= $line;
}
rewind($handle);
fwrite($handle, $fileinfo);
fclose($handle);
?>

I get errors when I run that script! Thanks for the reply though, and it does point me in the right direction, looking for </body> via string matching. I'm trying this code out to see if it works...

	extract($HTTP_POST_VARS);	
	$fpoint = fopen('http://www.domain.com/link_list.html', "r+");
	$body = "</body>";
	$fileinfo = "";	
	while (!feof($fpoint))
	{
		$line = fgets($fpoint);
		if(!(strpos($line, $body) === false))
		{
			$offset = strpos($line, $body);
			fseek($fpoint, $offset);
			$addurl = "<a href='http://www.domain.com".$article_URL."'>".$headline."</a>\n";
			$fileinfo .= $addurl;			
		}	
	}
	fwrite($fpoint, $fileinfo);
	fclose($fpoint);

But I keep getting the same error that I got with your script:

not valid file handle resource.
and
wrong parameter count for fgets()

these errors appear both in Sam's code and my code. I changed the file fopen() calls to a relative domain as well (to avoid the http thing) and still no luck. Any ideas?

Are you sure that PHP is not running in safe mode?

That code runs correctly on my machine. (PHP 4.2.2)

I'll check with the host. Did you try running my code, and if so did it work?
BTW, nice website 😉
