Imagick or header issue in wordpress and save that image to specific directory
Hi i write some code for images to be put side by side.I use Imagick library for that purpose.This is my code.
$im = new Imagick();
// session contain image path like upload/my.jpg
$im->readImage("http://localhost/wordpress3.5/".$_SESSION['imgname']);
$im->readImage("http://localhost/wordpress3.5/".$_SESSION['preimgurl']);
$im->resetIterator();
$combined = $im->appendImages(false);
/* Output the image */
$combined->setImageFormat("png");
header("Content-Type: image/png");
echo $combined;exit();
But the output is not what i suppose to be.this is output.I write this code under the plugin/ files.Also i want to save that image to directory like "localhost/wordpress/uplaod_pic/".
Solutions
You should use an image tag with the
src
tags containing the direct or base64 version of the image.
First example would be direct:
echo '<img src="http://localhost/wordpress3.5/'.$_SESSION['imgname'].'">';
Second would be using base64 with the data URI scheme, PHP Example:
echo '<img src="data:image/png;base64,'.base64_encode($combined).'">';
I would recommend the first method, simply because it looks like a product display, the images are most likely public and hotlinking can be busted if you choose.
In both examples, since the image is inline, you wouldn't need to set the content-type to an image.
You should also place the correct
mime type
within the second version, either
image/png
,
image/jpeg
or others depending on the image.
Edit : To extend this:
$combined
contains the image, so you want to save this, simple use:
file_put_contents('upload_pic/'.$time().'.png', $combined);
