Pass a variable into PHP function

[Adamhumbug]

Hi All,

I have a function that i want to pass a variable into so that i can do some SQL on it.

The information that i want to pass into it is a data-id on a button that is used to trigger the function.

The button that will be clicked is this

<div class='modaltrigger btn btn-primary' data-id='$itemId' data-toggle='modal'>Manage</div>

This button is being created by another function.

I would like to know either how i pass the variable from one function to another or how i pass it from the data-id to the function in php.

Thanks in advance.

To pass the value from the client click to PHP requires AJAX. 

for example, javascript onclick handler would

$.get(
    "ajax-handler.php",
    {"id" : $(this).data("id")},
    function (response) {
      // handle reponse
    }  ,
    "TEXT"
)

Then in "ajax-handler.php"

<?php
$result = myfunction($_GET['id']);

function myfunction (id) {
   // do something with id
   // return result
}
?>
