When I click a button:
- I need the JavaScript to perform some function.
- Also run PHP code as well.
How can we achieve this?

PHP is only run by the server and responds to requests like clicking on a link/button (GET) or submitting a form (POST).
HTML & JavaScript is only run in someone's browser.
<html>
<?php
function PhpFunction() {
echo 'A php function';
}
if (isset($_GET['JsFunction'])) {
PhpFunction();
}
?>
Hello there!
<a href='index.php?JsFunction=true'>Run PHP Function On Click Of This Link</a>
</html>
Alternatively , You can create a ajax request to run a php code in your server..
Ajax can help you to send an asynchronous request to the server that php (or other) can catch, in this way you can implement and play with some callback functions
$.ajax({
url : "yourScript.php", // the resource where youre request will go throw
type : "POST", // HTTP verb
data : { action: 'myActionToGetHits', param2 : myVar2 },
dataType: "json",
success : function (response) {
//in your case, you should return from the php method some fomated data that you //need throw the data var object in param
data = toJson(response) // optional
//heres your code
},
error : //some code,
complete : //...
});
in your php script, you'll receive the request posted throw the superglobal vars like POST (for this example)
<?php
$action = (string)$_POST['action']; //this is unsecure, its just for the example
if("myActionToGetHits" == $action) {
//here you have to call your php function and so on..
$data = hitsMonth();
echo $data;
exit;
}
here is html
<a href="#" onclick="javascript:functionName(arg1, arg2);">
This is a basic example to do it, there are lots of ways to do.
Have javascript do the submit:
function button1() {
// js code here
var formelt = document.getElementById("form1");
formelt.submit(); // this will submit the form to server
}
Example =>
<button class="btn-test">Btn Test</button>
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<script>
jQuery('.btn-test').click(function() {
js_do_something();
php_do_something();
});
function js_do_something() {
console.log('something done from js');
}
function php_do_something() {
console.log('something done from php');
jQuery.ajax({
type: "POST",
url: 'you_php_file.php',
data: {param: 'btn-test-click'},
success: function () {
console.log('success');
}
});
}
</script>
There you have how to execute a php function with on Onclick.
Execute PHP function with onClick
You can execute a Javascript function assuming you´re using jQuery like this:
jQuery('#id-button').on('click', function(){
// your function body
});
