call php file from javascript

Question

Hi I have searched the web but can't get this to work. I'm trying to call the file databaseUpdated.php (placed in the same folder as the index.php file) from a function that is called every 10 seconds.

If I place the following in the index.php

<script type='text/javascript'>updateboolean();</script>;

the function is runned so thats not the problem, the problem is that the php file is not read.

the file databaseUpdated.php

<body>
<?php

echo ("<script type='text/javascript'>updateboolean();</script>;");

?>
</body>

And here is my functions in the javascript

 $(document).ready(function(){
        setInterval(function() {
        $.get("databaseUpdated.php");//Can't get this to work any obvious reason for this (And yes I have jquery working)?
        return false;            
    }, 10000);
    });



    function updateboolean(){
        alert("Database updated");
        document.location.reload(true);
    }

Thanks in advance =)

Edit

_________________________________________________________________________________________

When I do

alert(data); in the below function I get the result as the image will show

$(document).ready(function(){
            setInterval(function() {
               $.get('databaseUpdated.php', function(data) {
               alert('Load was performed.');
               alert(data);
               eval(data);
            });
        }, 5000);
   });

enter image description here

But the "eval(data)" doesn't seem to work

What error did you get in the console? Is there a HTTP request? What is the status code? — JackPoint

So, you have to load this php file every 10 seconds that, in your mind, should call a Javascript function? Why don't you just call the function every 10 seconds instead? — MaxArt

Define "Can't get this to work" - start by verifying that a request is made to that url using your browser (e.g. chrome network tab) - and that the response (which you're ignoring - that's "ok") is not a http error. — AD7six

there is so much wrong loading a php file which writes a string which you eval which calls a js function - instead of e.g. returning json and if (data.success) { callthisFunction(); } or at the very least using getScript - since that's what you're doing. — AD7six

$.get("databaseUpdated.php"); // This will only return contents of that file The scripts in that file are not executed. To execute them you need to do eval(). So Try This

$.get('databaseUpdated.php', function(data) {
       eval(data);
    });

Also, may be you will require to change your php file as following:

echo ("updateboolean();");

where is your callback function for ajax this is how it should be

 $(document).ready(function(){
            setInterval(function() {
               $.get('databaseUpdated.php', function(data) {
               alert('Load was performed.');
            });
        }, 10000);
   });

Try this:

$(document).ready(function(){
      setInterval(function() {
           $.get('databaseUpdated.php', function(data) {
           alert("Database updated");
           // or alert(data); //in case you return data from php
           document.location.reload(true);
        });
    }, 10000);
});

By doing $.get("databaseUpdated.php"), you request the PHP page, but ignore the return results.

Try this:

PHP

echo "updateboolean();";

JavaScript:

$.getScript("databaseUpdated.php");
