Simple PHP contact form with Google reCaptcha

So, *everyone* needs a simple form to send emails, via PHP, but we also need a protection agains bots/spammers.
This is code that i’v grabbed from codeforgeek and improved since the original had a few errors that made it impossible to run/work/send email.

It uses Google reCaptcha and you need to register you site/domain on it and grab the site key and the secret key.

The form already has twitter bootstrap classes… but you can remove them! 🙂

The form.php – at the begin
	$to      = '[email protected]';
	$subject = 'Support Message';

	// keys from Google reCaptcha https://www.google.com/recaptcha/admin
	$sitekey = 'recaptcha_site_key';
	$secretkey = 'recaptcha_secret_key';

	$alert = '';

        		$alert = '<div class="alert alert-warning" role="alert">Please wait until the captcha protection give you a check mark.</div>';


			/* lets set the error message for the alert... */
			if ($alert=='')
				$alert = '<div class="alert alert-danger" role="alert">Some how you have been detected has a spammer.</div>';
			/* the email to you */
			$headers = 'From: '.$to.'' . "\r\n" .
                	'Reply-To: '.$email.'' . "\r\n" .
                	'X-Mailer: PHP/' . phpversion();
            		mail($to, $subject, $message, $headers);
			/* the copy of the email to the *client* */
			$headers = 'From: '.$email.'' . "\r\n" .
				'Reply-To: '.$to.'' . "\r\n" .
				'X-Mailer: PHP/' . phpversion();
			mail($email, 'COPY - '. $subject, $message, $headers);
			/* lets set the success message for the alert... */
			$alert = '<div class="alert alert-success" role="alert">Your email has been sent.</div>';
The html form
<form id="comment_form" action="" method="post">
	<input name="email" type="email" placeholder="Type your email" size="40" class="form-control" value="<?=@$email?>" ><br><br>
	<textarea name="message" rows="8" cols="39" class="form-control"  placeholder="Your message to us..." ><?=@$message?></textarea><br>
	<div class="g-recaptcha" data-sitekey="<?=$sitekey?>"></div><br>
	<input type="submit" name="submit" value="Send message" class="btn btn-default"><br>

Some where at the bottom/footer…

<script src='https://www.google.com/recaptcha/api.js'></script>


Hope it helps anyone! 🙂

PHP – check if a file was changed under 10 mins ago

I need to cache results of a PHP glob of a folder…
This folder gets files uploaded via FTP from time to time and I need to prevent the script to perform a glob every time that the page is accessed.


$file = 'content.json' ; 
$time = 600 ; //in seconds 

  echo 'does not exist' ;
  // lets call the function that makes the glob and create the content.json 
 if( time() - filemtime( $file ) <= $time ) 
 echo 'file last changed under 10 mins ago' ; 
 echo 'file last changed more than 10 mins ago' ;
 // lets call the function that makes the glob and create the content.json 

PHP exec in background

So, in one of my projects/products/services, I need to execute ffmpeg via PHP…
Usually I use at do send the job to a queue list.. unfortunately in two different clients’ servers somehow PHP + exec and at doesn’t work well….

This is how we send a PHP exec to background

exec(command > /dev/null 2>/dev/null &);


As seen on http://stackoverflow.com/questions/8961470/how-to-make-shell-exec-run-in-background-while-php-continues

PHP – 500 internal server error – cPanel

I’v been struggling for hours to solve a weird problem with PHP in a cPanel environment.

This is how my log (/usr/local/apache/logs/error_log) looks like

[Tue Dec 30 21:13:09 2014] [error] [client 88.94.5.xxx] SoftException in Application.cpp:601: Directory "/home/dee/subdomains/www2.domain.com/members" is writeable by group
[Tue Dec 30 21:13:09 2014] [error] [client 88.94.5.XXX] Premature end of script headers: index.php
[Tue Dec 30 21:13:09 2014] [error] [client 88.94.5.XXX] File does not exist: /home/dee/subdomains/www2.domain.com/500.shtml

I thought that was some bad configuration on .htaccess … but that was wrong!
On some environments we need to have the right file/directory permissions so it work…

  • files: 644
  • directories: 755
