PHP writing blank variable to file

If I try to just write $post_data to the text file it works just fine. But when I try to use $htmlMix I end up with <span></span>. No data from $_POST makes it through. Any ideas?

<?php
    $post_data = $_POST['sendie'];
    $htmlMix = '<span>' . $post_data . '</span>' ;
        $filename ='data.txt';
        $fp = fopen($filename, "a+");      
        fwrite($fp, $htmlMix . "\n");
         fclose($fp);
?>

It looks like the variables are fine to me... unless I've come late to the post and it's already been changed :)

It looks like a problem with the PHP POST variable. Could you check in your HTML/PHP that the name attribute is set for the correct form field? Otherwise all that will get written if anything is the span elements. :)

Thanks

Throughout your whole script you're not using a valid variable name for the fp variable.

$gross;

^ a valid variable is structured like that.

Please mark my answer as the 'best answer' if it helps you out!

Ah, chalk that up to a typo when I posted it to the forum. I should've just pasted it. -.- See anything else that may be the issue?
