I have a function that sends out site emails (using phpmailer), what I want to do is basically for php to replace all the placheholders in the email.tpl file with content that I feed it. The problem for me is I don't want to be repeating code hence why I created a function (below).
Without a php function I would do the following in a script
// email template file
$email_template = "email.tpl";
// Get contact form template from file
$message = file_get_contents($email_template);
// Replace place holders in email template
$message = str_replace("[{USERNAME}]", $username, $message);
$message = str_replace("[{EMAIL}]", $email, $message);
Now I know how to do the rest but I am stuck on the str_replace(), as shown above I have multiple str_replace() functions to replace the placeholders in the email template. What I would like is to add the str_replace() to my function (below) and get it to find all instances of [\] in the email template I give it and replace it with the placeholders values that I will give it like this: str_replace("[\]", 'replace_with', $email_body)
The problem is I don't know how I would pass multiple placeholders and their replacement values into my function and get the str_replace("[{\}]", 'replace_with', $email_body) to process all the placeholders I give it and replace with there corresponding values.
Because I want to use the function in multiple places and to avoid duplicating code, on some scripts I may pass the function 5 placeholders and there values and another script may need to pass 10 placeholders and there values to the function to use in email template.
I'm not sure if I will need to use an an array on the script(s) that will use the function and a for loop in the function perhaps to get my php function to take in xx placeholders and xx values from a script and to loop through the placeholders and replace them with there values.
Here's my function that I referred to above. I commented the script which may explain much easier.
// WILL NEED TO PASS PERHAPS AN ARRAY OF MY PLACEHOLDERS AND THERE VALUES FROM x SCRIPT
// INTO THE FUNCTION ?
function phpmailer($to_email, $email_subject, $email_body, $email_tpl) {
// include php mailer class
require_once("class.phpmailer.php");
// send to email (receipent)
global $to_email;
// add the body for mail
global $email_subject;
// email message body
global $email_body;
// email template
global $email_tpl;
// get email template
$message = file_get_contents($email_tpl);
// replace email template placeholders with content from x script
// FIND ALL INSTANCES OF [{}] IN EMAIL TEMPLATE THAT I FEED THE FUNCTION
// WITH AND REPLACE IT WITH THERE CORRESPOING VALUES.
// NOT SURE IF I NEED A FOR LOOP HERE PERHAPS TO LOOP THROUGH ALL
// PLACEHOLDERS I FEED THE FUNCTION WITH AND REPLACE WITH THERE CORRESPONDING VALUES
$email_body = str_replace("[{\}]", 'replace', $email_body);
// create object of PHPMailer
$mail = new PHPMailer();
// inform class to use smtp
$mail->IsSMTP();
// enable smtp authentication
$mail->SMTPAuth = SMTP_AUTH;
// host of the smtp server
$mail->Host = SMTP_HOST;
// port of the smtp server
$mail->Port = SMTP_PORT;
// smtp user name
$mail->Username = SMTP_USER;
// smtp user password
$mail->Password = SMTP_PASS;
// mail charset
$mail->CharSet = MAIL_CHARSET;
// set from email address
$mail->SetFrom(FROM_EMAIL);
// to address
$mail->AddAddress($to_email);
// email subject
$mail->Subject = $email_subject;
// html message body
$mail->MsgHTML($email_body);
// plain text message body (no html)
$mail->AltBody(strip_tags($email_body));
// finally send the mail
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent Successfully!";
}
}
