a-id3 | NET library written in C # to read and write MP3 file ID3 | Audio Utils library

I am trying to display a table, which i can edit. My table comes up empty, even though there are records in the table. Any help would be appreciated.

code for selecting data: select.php

Can you explain me where is the problem? Because I lost all my hope for this... Insert and load work but delete not... When I remove if statement from delete, it says id is undefined index. But why it should be undefined when I define it in var id = $(this).data("id3"); I think the problem will be somewhere in select.php with a button. I have lack of experience with AJAX so I ask you for help with this problem.

Thank you for response. (sorry for the language)

Index.php

I was trying to implementing an onClick handler for a div element. The parent div has data parameters present while the child divs do not have anything. When i clicked the children divs the onlick handler was being called but no data-parameters were present. And if i click the parent element then i could find the data-parameters. My question is if onclick action can be passed to the child elements how to do the same for data elements?

When i click the parent elements the log i get:

I can't seem to find out the correct way to write this script; can someone please point me in the right direction, or offer an alternate way. I have looked but cannot find any relative examples. I am pulling info from a database with php/mysqli and echoing it in prospective divs with an onclick pointing to a javascript function. This all works great. The problem I am having is the 'innerHTML' includes an onclick pointing to a javascript function also; this doesn't seem to work. Is it possible to have a document.getelementbyid('somthing').innerHTML that contains a function call? I am not sure if I asked that write. The code is below. Thanks for any help.

PHP - AJAX, and MySqli

I have a small application that allows me to add or delete a first and last name to a database within the webpage. I am using AJAX so the page updates instantly w/out refreshing. My issue is that if I delete all the users from the page, the ability to add user also disappears. Consequently, this is triggering my "if, else" statement to fire and I am left with a user table that reads simply, "Data not found". Any help will be GREATLY appreciated.

i have this javascript CODE in index.php:

Here's my html:

I have row of checkboxes received from database:

I am having problem getting the value of the row of my table using ajax and so far every time im getting its values its giving me nothing in return here is how i get it.
