crash if email server not connected

[phpanon]

Hello there,

 

Is there any code that i can add to my script that will catch the error if the email server is not connected and just run the code without sending the email without crashing.

 

$to      = '[email protected]';
		$subject = "Room ".$roomID." Successfully Booked";
		$message = "You have successfully booked a Meeting Room. \n \n Meeting Room : ".$roomID." \n Date: ".$bkgDate." \n Time Slot: ".$bkgTime.". \n \n This is a confirmation email. Do not reply. \n \n \n \n RIAS Plc \n Insurance for the over 50's.";
		$headers = 'From: [email protected]' . "\r\n" .
    					'X-Mailer: PHP/' . phpversion();

		mail($to, $subject, $message, $headers);

		$query2 = "insert into booking values ('','".$roomID."','".$empID."','".$bkgDate."','".$bkgTime."')";
		$result2 = mysql_query($query2, $connection) or die ("Unable to perform query<br>$query2");

		$message4 = "Meeting Room Booked ";
		header("Location: MeetingMain.php?message4=$message4");
		exit();

mail($to, $subject, $message, $headers);

will return false if it fails

 

maybe this!! before mailing!

<?php
$mHost = ini_get('SMTP');
$mPort = ini_get('smtp_port');
$fp = fsockopen($mHost, $mPort, $errno, $errstr, 30);
if (!$fp)
{
die("Mail Server down");
}
?>

Hi,

 

thanks for taking a loook.

 

Is it possible for u to explain what this bit of code does?!

[MadTechie]

sure

<?php
$mHost = ini_get('SMTP'); //Gets SMTP (out going mail servers domain/ip) from the php.ini file
$mPort = ini_get('smtp_port'); //Gets SMTP port (out going mail servers port) from the php.ini file probably (port 110)
$fp = fsockopen($mHost, $mPort, $errno, $errstr, 30); //Connects to the mail server (wait a max of 30 seconds)
if (!$fp) //if their was a connection then the server and port are open so should be okay 
{
die("Mail Server down");
}
?>

 

of course the mail server could be open on that server and the port be okay but another problems could mess things up, but then your need to add more tests,

something like

<?php
$data = "";
while (!feof($fp)) {
        $data .= fgets($fp, 128);
    }
//check $data for messages etc
?>

Hi thanks,

 

I have implemented that code as such...

else
	{

		$mHost = ini_get('SMTP'); //Gets SMTP (out going mail servers domain/ip) from the php.ini file
		$mPort = ini_get('smtp_port'); //Gets SMTP port (out going mail servers port) from the php.ini file probably (port 110)
		$fp = fsockopen($mHost, $mPort, $errno, $errstr, 30); //Connects to the mail server (wait a max of 30 seconds)
		if (!$fp) //if their was a connection then the server and port are open so should be okay 
		{
			$query2 = "insert into booking values ('','".$roomID."','".$empID."','".$bkgDate."','".$bkgTime."')";
			$result2 = mysql_query($query2, $connection) or die ("Unable to perform query<br>$query2");

			$message4 = "Meeting Room Booked ";
			header("Location: MeetingMain.php?message4=$message4");
			exit();
		}
		else
		{
			$to      = '[email protected]';
			$subject = "Room ".$roomID." Successfully Booked";
			$message = "You have successfully booked a Meeting Room. \n \n Meeting Room : ".$roomID." \n Date: ".$bkgDate." \n Time Slot: ".$bkgTime.". \n \n This is a confirmation email. Do not reply. \n \n \n \n RIAS Plc \n Insurance for the over 50's.";
			$headers = 'From: [email protected]' . "\r\n" .
    					'X-Mailer: PHP/' . phpversion();

			mail($to, $subject, $message, $headers);

			$query2 = "insert into booking values ('','".$roomID."','".$empID."','".$bkgDate."','".$bkgTime."')";
			$result2 = mysql_query($query2, $connection) or die ("Unable to perform query<br>$query2");

			$message4 = "Meeting Room Booked ";
			header("Location: MeetingMain.php?message4=$message4");
			exit();
		}
	}

 

But now I am getting this error

 

Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:25 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ) in C:\wamp\www\Build\MeetingQuery.php on line 41

 

Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\www\Build\MeetingQuery.php on line 41

Other than the warning did it handle the failed connection okay ?

also to hide the "warning" append a @ to it

$fp = @fsockopen($mHost, $mPort, $errno, $errstr, 30); //Connects to the mail server (wait a max of 30 seconds)

[phpanon]

Now im getting an "HTTP 500 Internal Server Error"

 

and it doesn't seem to be writing the query to the database even if it doesnt connect to the server.

[phpanon]

can anyone help with this??  :-\

[MadTechie]

Adding the @ caused a error 500 ?

remove the @ and post all the errors..

as a surpressed warning shouldn't cause an error 500!

[phpanon]

I get the message i posted earlier if i remove the @...

 

Warning: fsockopen() [function.fsockopen]: unable to connect to localhost:25 (A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. ) in C:\wamp\www\Build\MeetingQuery.php on line 41

 

Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\www\Build\MeetingQuery.php on line 41

[MadTechie]

Ahh your time limit is also 30 seconds

try this

<?php
set_time_limit(30); //reset timeout. 
//and reduce the timout on the socket
$fp = @fsockopen($mHost, $mPort, $errno, $errstr, 20); //Connects to the mail server (wait a max of 20 seconds)
set_time_limit(30); //reset timeout. again!
?>

Thanks, that works!
