Question about saving a textarea to a .txt file

ddrfreek

Basically that's my question right there. I'm trying to find a way to save the text in a textarea field to a .txt file.

Right now I have a script that's supposed to do the same thing, but for a .css file, and it's not working. I know this is a bit of a big request, if you want I can post the current script I'm using.

Thanks for the help.

Alright, here's my script. It's split up into two files, because I'm trying to have one file that process all of my forms by identifying their type.

So, the first file contains:

$fh = fopen("http://www.doghousecomics.com/doghousecomics/dhcstylesheet.css", "r");
#reads each line into the $stylesheet array until it reads the last line and adds it.
while(!feof($fh))
{
$stylesheet[] = fgets($fh);
}
fclose($fh);

echo "
300 lines 0nl3!!1
<form name=\"form1\" enctype=\"multipart/form-data\" method=\"post\" action=\"/member/uploadProcess.php\">
<textarea name=\"style\" cols=\"60\" rows=\"30\">
";

foreach( $stylesheet as $line )
{
echo $line;
}

echo "
</textarea>
<br>
<input type=\"hidden\" name=\"type\" value=\"Style Editor\">
<input name=\"submit\" type=\"submit\" value=\"Submit\">
</form>";

The form processor file contains:
if ( $POST['type'] == "Style Editor" )
{
$fh = fopen("/doghousecomics/dhcstylesheet.css", "w");
fwrite ( $fh, $POST['style'] );
fclose($fh);
header( "Location: styleeditor.php" );
exit();
}

And .... what do you mean "it's not working?" You mean it's walking up and down in the street outside waving signs?

No, I mean that there's no error, I just click the submit button on the textarea, it brings me back to the same page, and the file isn't edited.

It seems to be reading from the file into the form and then writing it to the same file.

Are you actually making any changes to the file in the textarea before submitting it

ddrfreek

Well, it reads $POST['style'], which although is originally the file written in, but when you hit submit, the new $POST['style'] is whatever was in the textarea when you clicked submit, and that's what it uses to write over the old file.

What I was getting at is, when testing this page are you just hitting the submit button or are you actually making changes in the text area before submitting it to see if it works

You could always do something like this which gives you feedback 😉

<?php

$file_loc = 'ddrfreek.css';

// No matter what, we want the contents of the text file:
$contents = trim(file_get_contents($file_loc));

if(isset($_POST['update'])) {
	if($_POST['update'] != $contents) {
		$fh = @fopen($file_loc, 'w');
		if(!$fh) $msg = '0Unable to open file for updating.';
		if(fwrite($fh, $_POST['update']) !== false) {
			$msg = '1The file has been successfully updated.';
			$contents = $_POST['update'];
		}
		if($fh)
			fclose($fh);
	}
	else
		$msg = '2The submitted contents were the same as the current file contents.  No update necessary.';
}
else
	$msg = '';

$lvl = substr($msg, 0, 1);
/*....................  RED ............ GREEN ... BLUE ....*/
$bgcolor =  ($lvl==0?'EE3B3B':($lvl==1?'7BCC70':'B0C4DE'));
$txtcolor = '000'; //($lvl==0 ?'000':($lvl==1?'000':'000'));
$msg = substr($msg, 1);

?>

Thanks for the help! Let me work through this and I'll see what happens.

And yes Clark, I am, but I assumed that would be obvious.
