I'm using Sendgrid API to send emails with PHP I can send to one email at once but I need to pass the $email variable as the bulk of emails

array(
         "email" => $email,
         "name" => $name
         )


  

$email variable set the parameter as a collection of emails example: $email="[email protected],[email protected],[email protected]"

How I do this?                                                                                                                                                                                                                                                                                                          

Answer 1

a) explode() email value with , to convert it to array

b) Apply loop on this array and send mail.

c) Make sure to check real value instead of $_POST['send']

<?php
    if (!empty($_POST['email']) && !empty($_POST['subject']))
    {
        $emails = explode(',',$_POST['email']);
        $subject = $_POST['subject'];
        $body = $_POST['message'];
        
        foreach($emails as $email){

            $data = array(
                "personalizations" => array(
                    array(
                        "to" => array(
                            array(
                                "email" => $email,
                                "name" => $name
                            )
                        )
                    )
                ) ,
                "from" => array(
                    "email" => $sender
                ) ,
                "subject" => $subject,
                "content" => array(
                    array(
                        "type" => "text/html",
                        "value" => $body
                    )
                )
            );
        
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, "https://api.sendgrid.com/v3/mail/send");
            curl_setopt($ch, CURLOPT_POST, 1);
            curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
            curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            $response = curl_exec($ch);
            curl_close($ch);
        }
           
    
    }
    ?>

Heyho Gi,

you can use implode() to convert an array into a string so you get your emails as array and then you could say $email = implode(",", $emails); and $email would be [email protected],[email protected],[email protected]. But I'm confused why you use an extern company to dot his! You can do this locally on your machine! Don't share too much data with other companies ;)
