When I save a image using the Image Intervention class my file saves but shows as blank. I send it a base64 string.
Currently My Code.
$file = Input::file($_POST['data']);
$img = Image::make($file);
$fileName = "profiles/".md5(time()).'.png';
$path = public_path($fileName);
if($img->save($path)){
$user = User::find(Auth::user()->id);
$user->location->start_image = $fileName;
$user->push();
}
print_r($_POST['data']) -> http://pastebin.com/BGbUeZhr
Thanks
I have tried $file = Input::file(base64_decode($_POST['data'])); This does not work
Maybe I'm missing something but using Input::file when you have the image as base64 looks just wrong to me. Input::file is for retrieving a file that has been upload with an html form.
Assuming $_POST['data'] is a base64 encoded image, try this:
$img = Image::make($_POST['data']);
Or even better:
$img = Image::make(Input::get('data'));

i want to resize uploaded image and store in folder.then show in web.
i used enctype="multipart/form-data" on form in blade.php.
file successfully show in web without resize.
when try to resize image i got error
controller.php
public function dili(Request $request)
{
$di = new diligent;
$di->jobtype = $request->jobtype;
$di->jobC = $request->jobC;
$di->details = $request->details;
$image = $request->file('image');
$path = $image->getClientOriginalName();
$destinationPath = public_path('img');
Image::make($image)->resize(300, 100)->save($image);
$a = $image->move($destinationPath, $path);
$di->image = $path;
$di->save();
$de = diligent::all();
return view('admin')->with('dw', $de);
}
Error Message
Encoding format (tmp) is not supported.
1) use getRealPath() inside Image::make()
2) save image in particular path. try like this.
if($request->hasFile('image')) {
$image = $request->file('image');
$filename = $image->getClientOriginalName();
$image_resize = Image::make($image->getRealPath());
$image_resize->resize(300, 100);
$image_resize->save(public_path('img/' .$filename));
}
Make sure you installed Image intervention library.
The Intervention image save() method requires a filename so it knows what file format (jpg, png, etc..) to save your image in.
The reason you are getting the error is it does not know what encoding to save the temporary image object (tmp) in.
Here is an example
->save('my-image.jpg', 90)
There is also a optional second parameter that controls the quality output. The above outputs at 90% quality.

I had base64 encoded data.
Look my code, please.
First of all, see my code.
$data = "data:image/png;base64,iVBORw0KGgoAAAA..........";
$image_array_1 = explode(";", $data);
$image_array_2 = explode(",", $image_array_1[1]);
$data = base64_decode($image_array_2[1]);
$imageName = uniqid().time().".png";
I want to set an extension .png to complete my file so that I can count this file extension by laravel method $image->getClientOriginalExtension() and others laravel file methods.
sorry for miss spell of language.
Hope I make you understand.
This works, although I cannot say if it's the best way to go about it. It's a full working example with a 1x1 black pixel png image. This assumes you already removed the data:image/png;base64, portion from the image data.
$data = base64_decode('iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAQAAAC1HAwCAAAAC0lEQVR
42mNk+A8AAQUBAScY42YAAAAASUVORK5CYII=');
// Create a temp file and write the decoded image.
$temp = tmpfile();
fwrite($temp, $data);
// Get the path of the temp file.
$tempPath = stream_get_meta_data($temp)['uri'];
// Initialize the UploadedFile.
$imageName = uniqid().time().".png";
$file = new \Illuminate\Http\UploadedFile($tempPath, $imageName, null, null, true);
// Test if the UploadedFile works normally.
echo $file->getClientOriginalExtension(); // Shows 'png'
$file->storeAs('images', 'test.png'); // Creates image in '\storage\app\images'.
// Delete the temp file.
fclose($temp);
I'm trying to upload base64 image to server.
I've already try many answers, but i always get the same errors.

How to save a PNG image server-side, from a base64 data string
https://www.reddit.com/r/laravel/comments/39wclp/how_to_convert_an_base64_image_string_to_an_image/
Convert Base64 string to an image file?
This code below should work.
$image = base64_decode(Input::get('image_cropped'));
$image_name= 'file_name.png';
$path = public_path() . "/images/" . $image_name;
file_put_contents($path, $image);
If you inspect the form sent from request the image encoded starts with data:image/png;base64, so try with:
$img = explode(',', Input::get('image_cropped'));
$img_name = 'file_name.png';
file_put_contents(public_path().'/images/'.$img_name, base64_decode($img[1]));
This worked for me.
So I'm receiving an image in base64 encoding. I want to decode the image and upload it in a specific directory. The encoded file is an image and I'm using $file = base64_decode($base64_string); to decode it. Uploading it via file_put_contents('/uploads/images/', $file); always results in failed to open stream: No such file or directory error.
So, how do I take the decoded string, and upload it on a specific path?
Thanks.
Your path is wrong.
/uploads/images
is checking for a folder in the / directory called uploads. You should specify the full path to the folder:
/var/www/vhosts/MYSITE/uploads/images
I had the same problem and finally solved using this:
<?php
$file = base64_decode($base);
$photo = imagecreatefromstring($file);
//create a random name
$RandomStr = md5(microtime());
$name = substr($RandomStr, 0, 3);
$name .= date('Y-m-d');
$name .= '.jpg';
//assign name and upload your image
imagejpeg($photo, 'images/'.$name, 100);
I want to return an image over an URL like http://placehold.it/500x500.
I have my URL http://example.inc/assets/image/35345, which calls an action on controller. The controller get some data (name, id, etc.) from database and also a binary string of the image content.
On the frontend site, i have my img tag, where i want to call the url in my src attribute.
<img src="http://example.inc/assets/image/35345">
Some more information, i use slim PHP Framework and my server is an ubuntu 13.x system (vagrant etc.). I am an typically frontend developer and dont have good skills # PHP.
Following snippets works:
$file = fopen($name, 'wb');
fwrite($file, $binaryData);
fclose($file);
but I dont want to generate files in a directory. Is this possible?
EDIT: Content-Type and Content-Length Headers are set, that is not the problem.
Grab the contents of the image, base_64 encode it, then return a a base64 image.
$file = file_get_contents($name);
list($width, $height, $type, $attr) = getimagesize($file);
echo '<img src="data:image/'.$type.';'.base64_encode($file).'"/>';
You should upload images in directory by using something like this. This code will upload your image in directory.
if ($_FILES['file']['name'] != "") {
$filename = $_FILES['file']['name']; //getting name of the file from form
$filesize = $_FILES['file']['size'];
$info = new SplFileInfo($filename);
$ext = $info->getExtension();
$filesize1 = ($filesize * .0009765625) * .0009765625;
if (!($ext == 'jpg' || $ext == 'png' || $ext == 'jpeg')) {
//set some error message and redirect
}
if ($filesize1 >= 5.0) {
//set message image size should be less than 5 mb
}
$target_path = $_SERVER['DOCUMENT_ROOT'] . "../images/profile_images/";
move_uploaded_file($_FILES['file']['tmp_name'], "$target_path" . $_FILES['file']['name']) or
die("Could not copy file!");
}
Insert image name(with extension) in database.($filename here)
Fetch image name from database and store in variable($profile_image here),use it in img src.
<a href='../images/profile_images/$profile_image'><img alt='Avatar' src='../images/profile_images/$profile_image'></a>
You can use only Anchor tag to redirect user on image in another tab in browser.
hope this answer will help you.
Because i had an mssql database with iso charset i have converted all of my results to utf-8, the problem was, that the bytestring also converted to utf-8.
after non converting the bytestring i also returned the bytestring and set the header content type to image/extension
