How should I call jquery from my php page?

This is my php page:

<form action="#" method="post">
    <input type="file" name="fileInput" id="fileInput" />
    <input type="submit" value="submit" disabled />
</form>
<div id="result"></div>

And this is the js file:

$(document).ready(
    function(){
        $('input:file').change(
            function(){
                if ($(this).val()) {
                    $('input:submit').attr('disabled',false);
                }
            }
            );
    });

Thanks!

If both your js file and jquery are linked in your page, then this code will execute automatically when the page is done loading.

use

<script></script>

and put your code in between them on PHP Page.

Suppose you have your JavaScript code in a file 'yourFile.js'. Your PHP and JavaScript file should be in the same directory. In php file, just add

<script type="text/javascript" src="yourFile.js"></script>

This line of code should be placed before the <head> tag. If your page dpnt have any <head> tag and only PHP code, then just add the line at the begining of the PHP file

When I put the js file link on the head; the link is as follow:

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

I got the error as follows:
