javascript - How to read blob content appended as formData.append

one text

Solution:

Remove the last ',' int fd.append('blob', blob, );.

Check your variable $_POST server side with var_dump.

For help u, u can create a div like <div id="output"></div> and print the server response by changing this if

if (xhr.readyState == 4 && xhr.status == 200) {
   console.log(xhr.status);
}

into this if

if (xhr.readyState == 4 && xhr.status == 200) {
   console.log(xhr.status);
   document.getElementById('output').innerHTML = xhr.responseText;
}

EDIT :

Data not in the $_POST but in the $_FILES
