WOW :) I finally found where the problem comes from!
I changed this:
<script src="https://code.jquery.com/jquery-1.11.2.min.js"></script>
With this:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
And then when i clicked delete button, the alert message pointed at that html part you asked me to delete from delete-action.php, and now when i click delete button, a popup message appears with text "Success" and the html table refresh itself at the same time, great:)

Oh! i'm sorry i found the problem. I forgot to change this part:

$servername = "localhost";
$dbname = "mydbname";
$dbusername = "mydbusername";
$dbpassword = "mydbpassword";

@lps i used that way but faced mhith some errors.

Hi.
In my CMS, when i type a content for a new post in the textarea, like this:

one
two
three
four
five
six

and then click the submit button, it will save in the db table like the way i have typed, every word in a separate line.
But when the script echo the post on the page, i see all words are in one line like this:

one two three four five six

Why? Do i have to type tags like <br> while typing the content on the text area?! But users must feel free to write their posts without thinking about using html tags while they are typing!

Yes it work ok now. Thank you @cereal for clear explanation and for updating my code:) I understood it well.

Thank you @lps. I understood. I will do what you recommend to me.

Well, i find the problem myself.
The name of the file "Tutorial.kv" should be in lowercase, so i changed it to "tutorial.kv".

And also there was a little problem in "tutorial.kv" line 6. The ; after None was extra that i deleted.

Yes i understand and i tried it but i got this error:

Traceback (most recent call last):
  File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1535, in __call__
    return self.func(*args)
  File "./mydb", line 45, in show
    data_str += (row['colorname']) + '\n'
UnboundLocalError: local variable 'data_str' referenced before assignment

So i asked again.

Now it works because i have typed += and also data_str = "" wich i forgot to type before and was the cause of the problem.

Yesssssssssssss!!! It works :)
@Gribouillis, Thank you so much.

Well, i solved the problem myself finally :)

Yesssssssssss!! It works Gribouillis thank you so much :)
I've created some other functions and all of them works separately, nice!
