jQuery Ajax form two submit button in one form

Question

I have 2 button in one form. When I click the first or second button, both write example an alert, but the Ajax request doesn't run. I need a form, because i would like to upload images. I don't know what is the problem.

page.php

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>jQuery Ajax two submit in one form</title>
    <script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
</head>
<body>

<form id="animal-upload" method="post" enctype="multipart/form-data">

    <span>Name:</span>
    <input type="text" name="animalname" id="animalname">

    <span>Image:</span>
    <input type="file" name="imagefile" id="imagefile">

    <button type="submit" name="publish" id="publish">Publish</button>
    <button type="submit" name="save" id="save">Save</button>

</form>

<script>

$(document).ready(function() {

$('#animal-upload').on('submit', function() {

    return false;

});

$('#publish').click(function() {

    alert("Test");

});

$('#save').click(function(e) {

    e.preventDefault();

    $.ajax({

        url: "animal-upload.php",
        type: "POST",
        data: new FormData(this),
        contentType: false,
        processData: false,
        success: function(data) {

            alert(data);

        }

    });

});

});

</script>

</body>
</html>

animal-upload.php

<?php

$connect = mysqli_connect("localhost", "root", "", "test");

mysqli_set_charset($connect,"utf8");

$status = '';

$animalname = $connect->real_escape_string($_POST["animalname"]);

if ($_FILES['imagefile']['name'] != '') {

    $extension = end(explode(".", $_FILES['imagefile']['name']));
    $allowed_type = array("jpg", "jpeg", "png");

    if (in_array($extension, $allowed_type)) {

        $new_name = rand() . "." . $extension;
        $path = "animals/" . $new_name;

        if (move_uploaded_file($_FILES['imagefile']['tmp_name'], $path)) {

            mysqli_query($connect, "INSERT INTO animals (animalname,image) VALUES ('".$animalname."','".$path."')");

            $status = 'Successful!';

        }

    } else {

        $status = 'This is not image file!';

    }

} else {

    $status = 'Please select image!';

}

echo $status;

?>

After trial and errors I found the script work if you change this line :

data: new FormData($("#animal-upload")[0]),

Because that selects the form object.

You may consider some security tips :

Don't divulge your password in public
Don't let your database users connect without passwords
Make a user with strict minimum privileges just for the purpose to connect to your database from PHP scripts (it's called the principle of least privileges)
Rename your uploaded file

For the file upload to work :

Make sure you have the right permissions on the directory pointed by upload_tmp_dir in php.ini file
You may need to check that your file size doesn't exceed the memmory_limit directive too

good luck,
