Sending email to multiple Recipients with swiftmailer

php forms email swiftmailer newsletter

Solution 1

According to this document

// Using setTo() to set all recipients in one go
$message->setTo([
  '[email protected]',
  '[email protected]' => 'Person 2 Name',
  '[email protected]',
  '[email protected]',
  '[email protected]' => 'Person 5 Name'
]);

You can input array directly into setTo, setCc or setBcc function, do not need to convert it into string

Solution 2

You should validate the input-data by first exploding them into single E-Mail-Adresses and push the valid Data into an Array. After this you can suppy the generated Array to setTo().

<input type="text" name="recipients" value="[email protected];[email protected];...">

On Submit

$recipients = array();

$emails = preg_split('/[;,]/', $_POST['recipients']);
foreach($emails as $email){
 //check and trim the Data
 if($valid){
  $recipients[] = trim($email);
  // do something else if valid
 }else{
  // Error-Handling goes here
 }
}

I am trying to use swiftmailer in my project so that I can send html newsletter to multiple users. I have searched thoroughly but all i got never worked for me. I want to paste more than one recipient in the form input field seperated by comma and send the html email to them. I set the recipients to a variable($recipients_emails) and pass it to setTo() method in the sending code, same with the html_email.

Questions are: Q1 How do i send to more than one recipient from the recipient input field.

I tried this:
```
if (isset($_POST['recipients_emails'])) {
    $recipients_emails  = array($_POST['recipients_emails'] );
    $recipients_emails= implode(',',$recipients_emails);
}
```
Q2 How do I make the Html within heredoc tag. when i tried concatenating like this ->setBody('<<<EOT'.$html_email.'EOT;', 'text/html'); , my message would appears with the heredoc tag.
```
if (isset($_POST['html_email'])) {
    $html_email = $_POST['html_email'];
}
```
How do I have input from $_POST['html_email']; to be within EOT tag;

this in part of swiftmailer sending script ;
```
$message = Swift_Message::newInstance()
        ->setSubject($subject)
        ->setFrom($from)
        ->setTo($recipients_emails)
        ->setBody($html_email, 'text/html');
```
Nota bene : Am still learning these things.

I know if i set the whole html within heredoc tag and assign to a variable , it would work, but what am looking at is having to paste the html code into the message field and make it be within heredoc before sending to a user email. It works without the heredoc tag but am not sure its advisable to do without the tag. If I try adding heredoc withing the message field , it all appears like text in the inbox. which means it is not processed by php.

I am not 100% sure what you are asking there. You can have a 'template' in your php code and just replace variables in the heredoc using curly braces as demonstrated above. You can only use heredoc when assigning to a variable its the ONLY way it works.

OK now i got it. Thanks that 's solved . Next it passing the recipients as an array of emails.

I don't want to do it that way. I don't need to paste recipients in the within the code before i would send to them. For example I have 100 emails to sent to , would i have to setTo each of the emails .

Just change to...... implode(" ',' ",$recipients_emails); but cast to a variable first so you can prepend and append the single quotes... look here tehplayground.com/iapnnaWSR9iqYrMn

I thought emails should be comma delimited rather than semicolon ?

I don't know. But you can use multiple Delimiters with preg_split() if needed.
