PHP error while saving text file

Question

I wanna save on my server a text file and so I'm using the file_put_contents with some flags. I also have to import a value from an <input type="text" name="loaded"> field that contains some people's names.

<input type="text" name="loaded">
 //other html code
<form method="post" action="scriptf.php">
<input type="submit" value="Go!" />
</form>

This script saves on foldera/file.txt only "Lucas Smith (lsmith334) +" but it is missing the ex (which contains the text in that input).

<?php
$file = 'foldera/file.txt';
$ex = $_POST['loaded'];
$person = "Lucas Smith (lsmith334) + ".$ex;
file_put_contents($file, $person, FILE_APPEND | LOCK_EX);
?>

What am I doing wrong?

so do a `var_dump($_POST)` and/or `var_dump($ex)` to ensure that your extra data is actually coming through. As written, this code is fine. — Marc B, Jul 02 '13 at 18:51
though i wouldnt let a post variable dictate the path with no filtering — exussum, Jul 02 '13 at 18:52
so if I put "var_dump($_POST)" instead of "$ex = $_POST['loaded'];" it should work? — Alberto Rossi, Jul 02 '13 at 18:53

your input isn't inside the form

<form method="post" action="scriptf.php">
<input type="text" name="loaded">
<input type="submit" value="Go!" />
</form>

should work, all of the inputs need to be inside the form tags

Nesting forms is a bad idea, and should be completely avoided, I can't think of a good reason to nest them

its actually agaist the standard too Can you nest html forms?

multiple forms is no problem, nested forms is

why nested forms ? the submit button which is pressed is the form which is sent. Nested forms are a bad idea – exussum Jul 02 '13 at 18:56
eh I have a
because I'm importing a Javascript function from an external file, I need that
– Alberto Rossi Jul 02 '13 at 18:57
That doesnt make sense ? you need a script to import a javascript function ? – exussum Jul 02 '13 at 18:59
Yes it does and yes I need. – Alberto Rossi Jul 02 '13 at 19:00
Could you give a better example - i cant think of a single situation where nested forms would be the wanted outcome – exussum Jul 02 '13 at 19:01
