Remove base_url() from path.
OR
Check this out
jQuery :
$(document).on('click', '#upload', function () {
let form_data = new FormData();
let data_url = document.getElementById('my_image').toDataURL('image/png');
data_url = data_url.replace(/^data:image\/(png|jpg|jpeg);base64,/, '');
form_data.append('uploaded_image', data_url);
$.ajax({
url: 'upload-avatar',
method: 'post',
data: form_data,
dataType: 'json',
contentType: false,
async: true,
processData: false,
cache: false
});
});
PHP :
$img = $this->request->getPost('uploaded_image'); // for ci4
$img = $this->input->post('uploaded_image'); // for ci3
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace('data:image/jpeg;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$file_data = base64_decode($img);
file_put_contents(/* my_path and my_file_name */, $file_data);
