I'm trying to create an img object from canvas element and upload the image to the server:
var img = new Image();
img.src = c2.toDataURL("image/jpeg", 0.95); // c2 is the canvas element
var formData = new FormData();
formData.append('img', img);
$.ajax({
url: 'pro01.php',
cache:false,
contentType: false,
processData: false,
type: 'post',
data: formData,
success: function(data) {
console.log(data);
}
});
pro01.php
$img = $_FILES['img'];
$target_dir = "images/";
$target_file = $target_dir . basename($_FILES["img"]["name"]);
move_uploaded_file($_FILES["img"]["tmp_name"], $target_file);
Console: <b>Notice</b>: Undefined index: img in...
Any help?
Instead on making it an image just convert the canvas to base64
:
var canvas = document.getElementById('myCanvas');
var dataURL = canvas.toDataURL();
Now send it:
$.ajax({
type: "POST",
url: "pro01.php",
data: {
imgBase64: dataURL
}
To receive it in php ( pro01.php ):
Get it from the post request, remove the start and call base64_decode()
on the posted value:
$img = $_POST['imgBase64'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$fileData = base64_decode($img);
//saving
$fileName = 'photo.png';
file_put_contents($fileName, $fileData);
