Send attachments with PHP Mail()?
(16 answers)
Closed 3 years ago.
I have a html bootstrap form and have a php code that sends a email of form information. This has a google reCaptcha check before the email is sent.
I copied the code that does the validation of the text, the email sending and the recaptcha from another php form that works.
How can I make the php code send the 2 images it receives from the form bootstrap form as attachments in the email.
These are my file upload form elements
<form role="form" class="form" action='https://opeturmo.com/parapente_ecuador/competencia_form.php' method='post'>
<div class="form-group row">
<div class="col-12"><label for="photo">Adjunte su foto - Add a photo of you</label></div>
<div class="col-12"><p>IMPORTANTE: Adjunta una foto de tu cara. No de tu parapente o alguna otra cosa. Máx 10MB Tamaño: mayor de 400*400 px –IMPORTANT: A photo of your face. Not your glider or anything else. Max 10MB Size: not less than 400*400 px</p></div>
<div class="col-12"><input type="file" class="form-control-file" id="photo" accept="image/*" name="my_file"></div>
</div>
<div class="form-group">
<label for="pago">Adjunte su foto de pago - Add your payment photo</label>
<p>IMPORTANTE: Adjunta una foto de tu cara. No de tu parapente o alguna otra cosa. Máx 10MB Tamaño: mayor de 400*400 px –IMPORTANT: A photo of your face. Not your glider or anything else. Max 10MB Size: not less than 400*400 px</p>
<input type="file" class="form-control-file" id="pago" >
</div>
and this is my php
<?php
//Checking For reCAPTCHA
$captcha;
if (isset($_POST['g-recaptcha-response'])) {
$captcha = $_POST['g-recaptcha-response'];
}
// Checking For correct reCAPTCHA
$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=6LcPkZEUAAAAAL4DJYl-y3iOl1TdavmqhsghRXeU&response=" . $captcha . "&remoteip=" . $_SERVER['REMOTE_ADDR']);
if (!$captcha || $response.success == false) {
header('location: ' . $_SERVER['HTTP_REFERER']);
} else {

//redirect back to form
header('location: ' . $_SERVER['HTTP_REFERER']);

}
?>
I haven't done much with php so I am lost with this.
