Hi,
I’m trying to use the OCR Engine2 within PHP but I can’t seem to get it working. I tried looking at some other forms but nothing seems to help.
In the Processing.php file this is the code. All help is appreciated. Thank you.
<?php
> if(isset($_POST['submit']) && isset($_FILES)) {
> require __DIR__ . '/vendor/autoload.php';
> $target_dir = "uploads/";
> $uploadOk = 1;
> $FileType = strtolower(pathinfo($_FILES["attachment"]["name"],PATHINFO_EXTENSION));
> $target_file = $target_dir . generateRandomString() .'.'.$FileType;
> // Check file size
> if ($_FILES["attachment"]["size"] > 5000000) {
> header('HTTP/1.0 403 Forbidden');
> echo "Sorry, your file is too large.";
> $uploadOk = 0;
> }
> if($FileType != "pdf" && $FileType != "png" && $FileType != "jpg") {
> header('HTTP/1.0 403 Forbidden');
> echo "Sorry, please upload a pdf file";
> $uploadOk = 0;
> }
> if ($uploadOk == 1) {
>
> if (move_uploaded_file($_FILES["attachment"]["tmp_name"], $target_file)) {
> uploadToApi($target_file);
> } else {
