Email Photos

NZ_Kiwis

Is it possible to email a photo as an attachment without saving it first?

dagon

yes, asuming you have it as a string.

A photo image as a string?

dagon

well what format is the unsaved image ?

NZ_Kiwis

it's just a GD Lib image I create

dagon

then its probably a resource you can convert to a string with

ob_start();
imagejpeg($imgresource);
$data = ob_get_clean();

then attach to email as usull

NZ_Kiwis

i can't find anything about attaching to an email in the manual though

NZ_Kiwis

okay I can get it to send an email with an attachement but it does not have the image in it..


header("Content-Type: image/JPEG");

imagejpeg ($image, NULL, 98);


$to = "my@example.com";
$subject = "A test email";
$random_hash = md5(date('r', time()));	
$headers = "From: CC Reward Administrator";
$headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\"";
$attachment = chunk_split(base64_encode(file_get_contents($image)));

$output = "
--PHP-mixed-$random_hash;
Content-Type: multipart/alternative; boundary='PHP-alt-$random_hash'
--PHP-alt-$random_hash
Content-Type: text/plain; charset='iso-8859-1'
Content-Transfer-Encoding: 7bit

Hello World!
This is the simple text version of the email message.

--PHP-alt-$random_hash
Content-Type: text/html; charset='iso-8859-1'
Content-Transfer-Encoding: 7bit

<h2>Hello World!</h2>
<p>This is the <b>HTML</b> version of the email message.</p>

--PHP-alt-$random_hash--

--PHP-mixed-$random_hash
Content-Type: picture/jpeg; name=create_card.jpg
Content-Transfer-Encoding: base64
Content-Disposition: attachment

$attachment
--PHP-mixed-$random_hash--";

echo @mail($to, $subject, $output, $headers);



imagedestroy($image);

When i open the attachment picture viewer opens but it says the file was empty

NZ_Kiwis

Anyone?

What is $image? It looks like it's a GD image resource; [man]file_get_contents/man expects a string (e.g. the path to a file), not a resource.

Just send an html with <img src='your path'> ?

that is not an attachment

NZ_Kiwis

So perhaps like this?

$attachment = chunk_split(base64_encode(file_get_contents($_SERVER['PHP_SELF'])));

That won't work for a couple of reasons:

$_SERVER['PHP_SELF'] gives a path relative to the root of the website as if you were constructing a URL - NOT the path to the file on the filesystem itself.
Even if you fixed the above error, you'd be retrieving the contents of the PHP script itself... something tells me that's not what you're trying to attach?

NZ_Kiwis

I've just worked that out as I got the email saying you posted a reply. I've not got this but still get an error.

$Link = "picturepage.php?Msg=" . $Msg;
$attachment = chunk_split(base64_encode(file_get_contents($Link)));

bradgrafelman

[man]file_get_contents/man works on the local file system, and paths on a local file system don't have query strings.

NZ_Kiwis

okay so how else can I attach my image? those query strings are the writing on my picture

That means you are actually not retrieving the picture directly, but have a script that retrieves the image and also draws text on it. You could of course make a http request from your server to your server, but that's really unnecessary, and I'd not recommend it.

Assuming your text drawing script is not contained within a function, you could

# initial code for emailing stuff...
...

# since it's your script, you should know what variables are needed by it.
# I'm just assuming what variables are needed... and proceed to set them up
$textToDraw = 'Merry Christmas';
$imageFile = '/images/house_with_snow.jpg';
$imageMaxWidth = 200;
$imageMaxHeight = 200;

# Now everything is ready for text drawing - just include script
require 'imageScript.php'

# And you should obviously not only know what vars are needed by imageScript.php,
# but also what vars are set up in it...
# Once again, I have to guess since it's not my script, and I'm guessing
$image;    // really is an image resource now.


# rest of code for emailing stuff
...

However, it would make a lot more sense to wrap the image handling in a function.
imageScript.php

function drawText($file_or_gd_resource, $text, ...) {

return $imageResource;
}

emailScript.php

require 'imageScript.php';
$image = drawText('images/house_with_snow.jpg', 'Merry Christmas', $width, $height);

# rest of emailing stuff

As for the script that is used to draw text on images through your webserver, it will now draw text in the exact same way as your other script

$maxLength = 200;
$text = sanitizeInput($_POST['textToDraw'], 'string', 200);
$file = sanitizeInput($_POST['image'], 'imageFile', 'jpg');

require 'imageScript.php';
$image = drawText($file, $text);

Thanks so much for the reply, could I then attach my image to my email as shown earlier in the code?

My real trouble is getting the image on a email?
