How to call a PHP function on the click of a button

Posted By: Anonymous

I have created a page called functioncalling.php that contains two buttons, Submit and Insert.

I want to test which function is executed when a button gets clicked. I want the output to appear on the same page. So, I created two functions, one for each button.

<form action="functioncalling.php">
    <input type="text" name="txt" />
    <input type="submit" name="insert" value="insert" onclick="insert()" />
    <input type="submit" name="select" value="select" onclick="select()" />
</form>

<?php
    function select(){
        echo "The select function is called.";
    }
    function insert(){
        echo "The insert function is called.";
    }
?>

The problem here is that I don’t get any output after any of the buttons are clicked.

Where exactly am I going wrong?

Solution

Button clicks are client side whereas PHP is executed server side, but you can achieve this by using Ajax:

$('.button').click(function() {
  $.ajax({
    type: "POST",
    url: "some.php",
    data: { name: "John" }
  }).done(function( msg ) {
    alert( "Data Saved: " + msg );
  });
});

In your PHP file:

<?php
    function abc($name){
        // Your code here
    }
?>
