Overall just need to pass parameter to the php function.

Answer 1

There are few ways to get data from the user:

Pass data via url parameters:

<a href="index.php?foo=bar">Foo equals Bar</a>

<?php 

    $foo = (isset($_GET['foo'])) ? $_GET['foo'] : 'undefined';

    echo "foo equals $foo";
?>

A straight up form:

// index.php
// An example form that loops back to itself.
<form action="index.php" method="post" id="the_demo_form">
    <fieldset>
        <label for="foo">Foo</label>
        <input type="text" name="foo">  
    </fieldset>
    <input type="submit"/>
</form>
<pre>
<?php
    // the $_POST global contains the data sent in the request.
    var_dump($_POST);
 ?>
</pre>

Ajax
If you need to submit the data without reloading via javascript the page you would use AJAX.
This is an example using jQuery that catches the form submit event and sends the form without reloading the page.

// index.php
// An example form
<form action="index.php" method="post" id="the_demo_form">
    <fieldset>
        <label for="foo">Foo</label>
        <input type="text" name="foo">  
    </fieldset>
    <input type="submit"/>
</form>

<script>
 $(document).ready(function(){
    $("#the_demo_form").submit(function(event){ 
        // This prevents the browser from following the form.
        event.preventDefault();
        // We take the data and send it to server via AJAX.
        $.ajax({
            // set this to server side script
            url : "index.php",
            data : $(this).serialize(),
            success: function(data){
                alert("eureka!");
            }
        });
    });
});
</script>
