PHP logging form

[sgtlion]

This feels pretty beginner question, but I'm trying to log a form upload and I really can't get php code to fix it.

 

This is essentially my submission HTML form

<form method="post" action="./Registrator.php" id="register">
Username: <input type="text" name="username" id="username" size="25" value="" title="Username" />
<fieldset class="submit-buttons">
	<input type="reset" value="Reset" name="reset" /> 
	<input type="submit" value="Submit" name="submit" />
</fieldset>
</form>

 

But seriously, what php do I need in Registrator.php to simply write the entry to a log file log.txt, a new line at a time?

I can only assume this is like a three line php file. I've been looking for hours online, I must be idiotic, but this is getting silly, so I ask for your help.

 

Thanks for reading and for any help you have to offer.

What do mean?

 

Are you asking what code do you need in order for your script to work? So when the user clicks submit, it goes to the registration file which would register the user into a database?

[ManiacDan]

One line, actually:

 

file_put_contents('log.txt', $_POST['username'] . "\n", FILE_APPEND);

Basically yeah. Simply for it to log the username into a .txt file.

 

One line, actually:

 

I put this into my php file, and still nothing is being logged when submit is pressed. There is little on the form submit page but as mentioned. And my php file now consists solely of

<?php
file_put_contents('log.txt', $_POST['username'] . "\n", FILE_APPEND);
echo "Registration success.";
?> 

I've created log.txt in the same directory. What could possibly be going wrong?

Although, I guess it's possible my form could be submitting other hidden information in the post method than the username input, would that cause a problem?

 

Thanks very much for your help.

What do you get when you run this in your script? var_dump(is_writable('log.txt'));

[sgtlion]

Uh, hm. I get nothing at all. Whether I view the script directly or even use the submit button. I'm just left seeing a blank page.

 

That's kinda weird, I know PHP is functioning fine on the server, because there's a whole phpbb3 forum that functions on the same domain.

Now I'm just plain confused. Could it be a PHP settings thing?

Turn on error reporting, and you'll see why.

// Report all PHP errors
error_reporting(-1);

[scootstah]

// Report all PHP errors
error_reporting(-1);

 

And ini_set('display_errors', 1);

[sgtlion]

Alright, got round to enabling that. And still nothing. No error reports, nothing showing up at all.

Just blank everywhere.. Confusion is rampant..

 

Thanks very much for the assistance.

What are you using for an HTTP server? Try checking those error logs and see if anything comes up.

[ManiacDan]

View the source of the page.  I bet you'll see your PHP script in its entirety.

View the source of the page.  I bet you'll see your PHP script in its entirety.

 

Uhm, wow, you're entirely right. I'm not sure how to express how idiotic I feel. I've written working php pages, not dissimilar to this even, before.

So, perhaps more stupidly, uh, why is this happening?

 

Thanks very much for your assistance in my dumb times.

 

EDIT:

So I guess the problem was the character encoding Notepad was saving them in.

I changed it from Unicode to ANSI and it worked, the line of PHP did it's job perfectly.

 

Thanks to everyone who helped, I really appreciate it; and perhaps feel just, very slightly, redeemed in my idiocy for fixing it myself.

 

You are all basically the best.

[scootstah]

Notepad? Like, the one that comes with Windows?

 

Geez man, use a better tool. Try Notepad++ or Sublime Text 2.

[ManiacDan]

I like eclipsePDT, though it's slow.  I'm actually using Geany now and I love it, but as far as I know it's linux-only.

[scootstah]

I use Eclipse PDT as well, but I figured Notepad++ or Sublime Text are the closest (decent) thing to Notepad (a quick, no-frills editor).
