PHP Mysql error

[bcart]

Hi there

 

I'm not sure if this is a PHP or MySQL problem. I am currently running an exam booking system which at the checkout emails the booking administrator the details of the exams that have been booked.

 

If 1 person completes this then the system works perfectly however if more than 1 person tries to complete the booking at the same time then the email is not sent, it comes up with the following error message;

 

Warning: mail() [function.mail]: Failed to Receive in prog_admin\view_booking.php on line 88

 

Line 88 reads...

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

 

The data gets stored into a mysql database which again works perfectly even when multiple users are booking exams however I get an error message saying....

 

Could not connect to MySQL: Can't connect to MySQL server on 'localhost' (10056)

 

I'm assuming it's got something to do with the number of connections being opened up with the database at 1 time. Does anyone know how to solve the problem?

 

Any help would be much appreciated.

 

Cheers!

My actual script is this

 

<?php

ob_start();

session_start();

//Declare the includes
include ('../includes/main.php');
include ('../Connections/mysqli_connect.php');

$ta = $_SESSION['ta_name'];
$ref = $_SESSION['ref'];
$email = $_SESSION['email'];

//Exam Detail Query
$order_query = "SELECT * FROM exam_details WHERE ref='$ref' ";

//Run the query
$result_order_query = @mysqli_query ($dbc, $order_query);
$row = @mysqli_fetch_array ($result_order_query);
$records = $row[0];
$number = mysqli_num_rows($result_order_query);

$learner = $row ['learner'];

//Learner Query
$learner_query = "SELECT * FROM exam_learner_details WHERE id='$learner' ";

//Run the query
$result_Learner = @mysqli_query ($dbc, $learner_query);
$row_learner = @mysqli_fetch_array ($result_Learner);
$records_learner = $row_learner[0];

$i=1;

$body = '<h1>Review of Exam Booking</h1>';

do {
       
        //Exam Group / Title Query
        $exam_group = $row['exam_group'];
        $q_group = "SELECT exam_group FROM exam_group WHERE id='$exam_group'";
        $r_group = mysqli_query($dbc, $q_group);
        $row_group = mysqli_fetch_array($r_group);
       
        $exam_title = $row['title'];
        $q_title = "SELECT title FROM exam_title WHERE id='$exam_title'";
        $r_title = mysqli_query($dbc, $q_title);
        $row_title = mysqli_fetch_array($r_title);
       
        //Make the body of the email
        $body .= '

I have also come across the error message...

 

Warning: mail() [function.mail]: SMTP server response: 503 Bad command sequence in prog_admin\view_booking.php on line 88

 

Again this only happens when multiple users are booking people onto exams. With only 1 user it's working perfectly! 

 

Any ideas? I'm at a total loss!!!
