I'm trying to send an email with an image in base64 on the body with PHP using the code below, but the image never appears... If I change to an URL it works, but it doesn't with the base64... I tested the base64 on a new page only with <img src=base64> and worked too... What am I missing??
<?php
// recipients
$to = $_POST['email'];
// subject
$subject = 'Test';
// message
$message = '
<html>
<head>
<title>Test</title>
</head>
<body>
<img src="'.$_POST['imageFromOtherPage'].'"/>
</body>
</html>
';
// To send HTML mail, the Content-type header must be set
$headers = 'MIME-Version: 1.0' . "
";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "
";
// Mail it
mail($to, $subject, $message, $headers);
?>
Here is my base64 image example: http://jsfiddle.net/28nP4/
I tried different things and the only way I found was uploading the image and getting the URL, I got that from this link: http://j-query.blogspot.in/2011/02/save-base64-encoded-canvas-image-to-png.html
It is very simple:
<?php
// requires php5
define('UPLOAD_DIR', 'images/');
$img = $_POST['img'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = UPLOAD_DIR . uniqid() . '.png';
$success = file_put_contents($file, $data);
print $success ? $file : 'Unable to save the file.';
?>
And this generates an URL, so, instead of using <img src="'.$_POST['imageFromOtherPage'].'"/>, I use the generated URL. Worked perfectly!
<img src="'.$_POST['imageFromOtherPage'].'"/>
Your POST needs to start with data:image/png;base64, to form a base64 encoded data: URI.
But even if you fix this, it is well possible that the E-Mail client you're viewing the message in doesn't support the method at all. data:URIs are a relatively new phenomenon - at least in the chronology of E-Mail clients, most of which are still in the process of discovering that there's a technology called CSS. The tried and tested method for images in E-Mails is to embed the image as an inline attachment.
Here are some approaches that don't rely on a library: Make PHP send an email with an inline image attachment
However, using a library like Swiftmailer may take away a lot of pain. Here is the appropriate Swiftmailer documentation.
Try to test if $_POST['imageFromOtherPage'] contains the base64 , probably the code is too long for a Post, you would need to use php://input .
i have the same problem, and finaly i resolved it. It might be helpful for you: You can use SwiftMailer, but you must to add new Image TextHeader 'Content-Location'. Here is the code:
$message = \Swift_Message::newInstance()->setSubject($subject)->setFrom($fromEmail, 'Name')->setTo($toEmail)->setBcc($bccEmails);
/*get uniqueID from cid:uniqueID */
$imageID = explode(':', $message->embed(\Swift_Image::fromPath('pathToTheImage')->setContentType('image/png')))[1];
/*Add Content-Location to image header*/
/** @var \Swift_Image $image */
$image = $message->getChildren()[0];
$image->getHeaders()->addTextHeader('Content-Location', $imageID);
$message->setBody('here you will have some html with <img src=$imageID alt="Embed Image">', 'text/html');
$mailer->send($message);
function for get all images url :
function getImagesFromMsg($msg, $tmpFolderPath)
{
$arrSrc = array();
if (!empty($msg))
{
preg_match_all('/<img[^>]+>/i', stripcslashes($msg), $imgTags);
//All img tags
for ($i=0; $i < count($imgTags[0]); $i++)
{
preg_match('/src="([^"]+)/i', $imgTags[0][$i], $withSrc);
//Remove src
$withoutSrc = str_ireplace('src="', '', $withSrc[0]);
//data:image/png;base64,
if (strpos($withoutSrc, ";base64,"))
{
//data:image/png;base64,.....
list($type, $data) = explode(";base64,", $withoutSrc);
//data:image/png
list($part, $ext) = explode("/", $type);
//Paste in temp file
$withoutSrc = $tmpFolderPath."/".uniqid("temp_").".".$ext;
@file_put_contents($withoutSrc, base64_decode($data));
}
//Set to array
$arrSrc[] = $withoutSrc;
}
}
return $arrSrc;
}
