Now we need a create php script to check values submitted by the form, prepare the message, send it to Ez Texting via our API, and process a response.
Copy and past this chunk of php into your favorite editor and save it as 'send.php' in the same directory as your form:
<?php
if (!empty($_POST)) {
/* check if phone number is valid */
$phone_number = trim($_POST["phone_number"]);
if (empty($phone_number)) {
exit("Phone number cannot be blank.");
}
if (strlen($phone_number) != 10) {
exit("Invalid phone number. Phone number length should be 10 digits.");
}
if (!is_numeric($phone_number)) {
exit("Invalid phone number. Phone number should contain only digits.");
}
/* check if message body is not blank and doesn't exceed allowable limit */
$subject = trim($_POST["subject"]);
$message = trim($_POST["message"]);
if (empty($subject) && empty($message)) {
exit("Message cannot be blank.");
}
// subject is wrapped in brackets and separated with a whitespace, so count for 3 extra characters
$strlen_subject = ($subject != "") ? strlen($subject) + 3 : 0;
$strlen_message = strlen($message);
$message_type = $_POST["message_type"];
if ($message_type == 1 && ($strlen_subject + $strlen_message > 160)) {
exit("In case of express delivery, message length should not exceed 160 characters.");
} elseif ($strlen_subject + $strlen_message > 130) {
exit("In case of standard delivery, message length should not exceed 130 characters.");
}
/* prepare data for sending */
$data = array(
"User" => "user", /* change to your EZ Texting username */
"Password" => "password", /* change to your EZ Texting password */
"PhoneNumbers" => array($phone_number),
"Subject" => $subject,
"Message" => $message,
"MessageTypeID" => $message_type
);
/* send message */
$curl = curl_init("https://app.eztexting.com/sending/messages?format=json");
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($curl);
curl_close($curl);
/* parse result of API call */
$json = json_decode($response);
switch ($json->Response->Code) {
case 201:
exit("Message Sent");
case 401:
exit("Invalid user or password");
case 403:
$errors = $json->Response->Errors;
exit("The following errors occurred: " . implode('; ', $errors));
case 500:
exit("Service Temporarily Unavailable");
}
}
?>
Now upload both files to your web server. Open your html file in a web browser. And try sending a message.
