So, I'm trying to call a php function from the same file where the javascript lies.

I'm trying to call the php function every 10 sec to add new items to the "li"

<script type="text/javascript" src=".10.2/jquery.min.js">

function addElement () {
var newLi = document.createElement("li");
var text = document.createTextNode("Teststring in <li>");

newLi.appendChild(text);
var ulnew = document.getElementsByClassName('new-item');
ulnew[0].appendChild(newLi)    
}
window.onload = function(){setInterval(function(){
    $.ajax( // I just copy pasted this part to
           {
               url: 'test.php',
               type: 'GET',
               success: function(output) 
               {
                      //alert(output);
                      document.write("It worked!"); 
               }
            }
        );// here I really have no idea what is suppose to happen here
},10000);}
</script>

<?php 

function echoTest(){
   echo 'item';
}

?>

Again, What I'm trying to do is Execute a php function every 10 sec. How am I going to do this? Please Help!

  • You may not call php function from the same file since the response will contains all page content (html/js) besides the function result. You have to place code of this function in a separate file. – hindmost Commented Feb 10, 2014 at 8:32
  • Send a parameter on your ajax and use its existence to echo a new li, just at the very top of the code. Inside the true block, make sure you use echo and die(); to prevent the script to return all the page code. – Fabiano Araujo Commented Sep 14, 2015 at 22:03

Reset to default 2 
    Try This

    <script type="text/javascript" src="http://ajax.googleapis./ajax/libs/jquery/1.10.2/jquery.min.js"></script>

    <script>
    window.onload = function(){setInterval(function(){
        $.ajax( // I just copy pasted this part to
               {
                   url: 'http://localhost/test.php',
                   type: 'GET',
                   success: function(output) 
                   {
                        var current = $("ul#updating-list").html();
                        $("ul#updating-list").html(current + "<li>" + output + "</li>");

                   }
                }
            ); // here I really have no idea what is suppose to happen here
    },10000);}
    </script>

and you need to call the function in php

<?php 

function echoTest(){
   echo 'item';
}
echotest();
?>

Well, you can do it this way as well, there surely are many ways to approach updating elements, but this is a way I find easy.

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title>Untitled Document</title>
        <script src="http://ajax.googleapis./ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    </head>
    <body>
        <ul id="updating-list"></ul>
        <script>
            window.onload = function(){
                setInterval(function(){
                    $.ajax({
                        url: "test.php",
                        type: "GET",
                        success: function(output){
                            var current = $("ul#updating-list").html();
                            $("ul#updating-list").html(current + "<li>" + output + "</li>");
                        }
                    });
                }, 10000);
            }
        </script>
    </body>
</html>

The PHP file should look something like this.

<?php
    if (!isset($_POST['call'])) {
        return;
    }

    $call = $_POST['call'];

    function result(){
        if ($call == "time") {
            echo(date('h:i:s'));
        }else{
            echo("Something fancy!");
        }
    }

    result();
?>

And like hindmost mented, you cannot call PHP functions from the same file as Ajax is in. You must have it in another file and call it from there instead.

You can call ajax on same php file with something like this

$('.botondb').click(function() {
            var val = $(this).val();
            $.ajax({
                url: '<?php echo basename($_SERVER['PHP_SELF']); ;?>',
                type: "GET",
                data: {
                    date:1234,
                    ajax:1
                },
               success: function(response) {
                    alert("exito!!! "+ response);
                },
                error: function(xhr) {
                    alert("error");
                }  
            });
        });

And this in the top of your php file:

if (isset($_GET['ajax'])){
            //do your stuff
            echo $ajaxvalue=$_GET['ajax'];
            exit;
    }
