mysql_query returns a resource, you need to loop through that resource to get the data back.

[Why do we use return true or return false after calling a JavaScript function?]

the call to the click is event driven, when you click on something a series of events bubble up through the component ( their native behaviours) when you use javascript to intercept these events you have to override their default behaviour.; so a button being what it is, if you click on it and it is ,for example, a button in a form, then if you return false it will stop the button from submitting the form. 

 

With this in mind you will see a lot of logic saying .... if field a in form is empty ... then stop button from completing its click event.... otherwise continue with the submit ( return true )

[Accessing functions in a higher level class]

i am not going to look through your entire code, but a few warning flags are a. you are contemplating using globals and b. you are not using __construct().

 

Looking though your setup you are declaring new instances of nest. i would advise you look at 2 things - Dependency Injection  and the IoC container

what does the getResultsByterm method do? you need to post more code

[Pass PHP/MYSQL values to ajax on click]

i understand you're question. user clicks remove -> the ajax calls sends data to back end -> record gets removed -> you get ajax response back -> remove the row from the page. Is this correct?

[php chat system ,i can't reload the div ,can anyone help me :(?]

so what you're trying to do is not create a chat system, but find one to fit your needs. If you dont want to code it yourself then ask in the freelance section and pay someone to do it for you

[Pass PHP/MYSQL values to ajax on click]

you need to listen to the click event of the remove button. something like this:

$('.remove').click(function(e){
  e.preventDefault();
  var me = $(this);
  var customer-id = me.data('customer-id');
  $.ajax({
   'url': 'processing/delete-playlist-items.php',
   'async': false,
    data: {
       customer-id: customer-id

     }, 
    success: function (response) {
 
        // use something like  me.getParent('td').fadeOut(); or something similar to remove the row
    }
  });

});

it would be a lot easier for the scope of the event if you added the data attributes you want to send to the anchor, then you can implement what i put there for you . hope it helps
