How to Call PHP Function in a Class from HTML Button Click

Question

I am a rookie PHP developer.

I have a PHP web project with an HTML page that contains an Add button. The name of the page is Awards.html. Elsewhere I have created a PHP class, Awards.php which contains a function.

The source code of my files is given as follows:

Awards.html

<div class="divparent">
    <div class="modal-header">
        <div class="btn-group">
            <button class="btn" data-bind="click: closeModal">Exit</button>
        </div>
    </div>
    <div class="modal-title">
        <h1 id="headerid">Awards</h1>
    </div>
    <div class="modal-body">
        <input id="hdnValueCurrentAwardSoid" type="hidden" value="null" />
        <div class="divleft">

            <input id="txtName" maxlength="80" type="text" class="water newpost1" placeholder="Award Name" tabindex="1" />        

            <section class="ThumbnailContainer">
                <img id="imgThumbnail" class="imgThumbnail" />
                <img src="http://localhost/rockontechnologies/Images/GreenRibbon.png" id="pictureribbon" class="pictureribbon" />
                <input type="text" contenteditable="false" readonly id="transformtext" />
            </section>

            <textarea id="txtdescription" placeholder="Description" class="water newpost1" rows="4" tabindex="2"></textarea>    

            <div class="ui-widget">
                <input id="txtIssueOrg" maxlength="50" type="text" placeholder="Issue Organization" />
            </div>

        </div>
    </div>
    <div class = "divbottom">
        <div id="divAddAward">
            <button class="btn" onclick="">Add</button>
    </div>
    </div>
</div>

Awards.php

    <?php

    class Awards
    {
        function clickFunction()
        {
            //Function that needs to be executed!
        }
    }

The problem here is that on the click event of the Add button, I need to call the clickFunction() of the Awards.php file. Can anyone please tell me how to do this?

Replies at the earliest will be highly appreciated. Thank you.

Solution

You should do something like that

<button class="btn" onclick="onrequest();">Add</button>

function onrequest() {
      $.post( 
          'example.php'
       ).success(function(resp){
            json = $.parseJSON(resp);
            alert(json);
       });
}

and in example.php call your function

$class = new Awards();
$method =  $class->clickFunction();
echo json_encode($method);

and in your clickFunction();

clickFunction(){
 $array = array(
   'status'  => '1'
 );    
 return $array; 
}
