Question

I have a function:

            $("button.btn-info").click(function() {
                 var id=this.id;
            });

So, and I have to get item from PHP array $records with ‘id’ number. I need to insert this item into ‘alert’ function, but I don’t know how I can pass variable from JS to PHP.

Please, tell me.

Answer 1

Use for example json_encode($records) and output it in a <script> tag in your html file like this:

<script type="text/javascript">
    var records = <?php echo json_encode($records); ?>;
</script>

this should usually stand before your other js code that depends on the records-var.

or else you could use ajax (jQuery.get) if you want to load this var dynamically.
