I have been attempting to upload a JSON file onto the server of 000webhost. Following a tutorial from w3schools (https://www.w3schools.com/php/php_file_upload.asp), I ended up removing all file checks as they were blocking JSON files. Below is the code for upload.php. I don't think it necessarily needs to be a php file, but I've tried everything I could think of.
<form action="upload_action.php" method="POST" encType="multipart/form-data">
<input type="file" id="uploadForm" name='uploadForm'><br>
<input class='hidden' id="submit" name="submit" type="submit" value="submit">
</form>
And here is the code for upload_action.php:
<?php
$target_dir = "datasets/";
$target_file = $target_dir . basename($_FILES["uploadForm"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload the file
} else {
if (move_uploaded_file($_FILES["uploadForm"]["tmp_name"], $target_file)) {
echo "The file ". htmlspecialchars( basename( $_FILES["uploadForm"]["name"])). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>
This script works perfectly with other file types that I've tested.
