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

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.

Answer 1

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;
}

Answer 2

first of you have to a instance of class which is like that
$class = new Awards();
then if you want to onclick event you should make a javascript code but how to get the function you can do like this
<?php echo $class->clickFunction(); ?>

I think you can't call a class directly from HTML in PHP you have to call it through HTTP by loading a page.
Hence, use a AJAX call to call Awards.php. Eg. with JQuery it could look like this $.get("Awards.php", function() {
alert( "success" );
})
In your php-file you should also call your class something like this <?php echo $class->clickFunction(); ?>
