    Hello,
    I am using for first time – Function Reference/wp enqueue script.
    My case:
    I have a script /jquery/.
    1. In header reference:

    <script language="javascript" type="text/javascript" src="/wp-includes/js/jquery/jquery-1.3.2.min.js"></script>

    In fact, it is tested out of WP and it is working with the current jquery in WP /1.8.3/. So, theorethicaly it doesnt need this reference, but it is working just with reference on. The problem is, that the other plugins stop to work, when i use this reference.

    2. In footer, there is a call of the function:

    <script language="javascript" type="text/javascript">
$(document).ready(function() {
						 .....................

						   }
						   )
</script>

    I read the official document http://codex.wordpress.org/Function_Reference/wp_enqueue_script

    But i am doing something wrong.
    Where i need to put this code and is there guide with practical examle, step by step?
    Or maybe there is another solution, different from wp enqueue script?
    Thanks

    This is the key of the solution:
    jQuery noConflict Wrappers
    The jQuery library included with WordPress is set to the noConflict() mode (see wp-includes/js/jquery/jquery.js). This is to prevent compatibility problems with other JavaScript libraries that WordPress can link.

    In the noConflict() mode, the global $ shortcut for jQuery is not available, so you can still use:

    jQuery(document).ready(function(){
    jQuery(#somefunction) …
    });
    but the following will either throw an error, or use the $ shortcut as assigned by other library.

    $(document).ready(function(){
    $(#somefunction) …
    });
    However, if you really like the short $ instead of jQuery, you can use the following wrapper around your code:

    jQuery(document).ready(function($) {
    // Inside of this function, $() will work as an alias for jQuery()
    // and other libraries also using $ will not be accessible under this shortcut
    });
    That wrapper will cause your code to be executed when the DOM is fully constructed. If, for some reason, you want your code to execute immediately instead of waiting for the DOM ready event, then you can use this wrapper method instead:

    (function($) {
    // Inside of this function, $() will work as an alias for jQuery()
    // and other libraries also using $ will not be accessible under this shortcut
    })(jQuery);
    Alternatively, you can always reasign jQuery to another shortcut of your choice and leave the $ shorcut to other libraries:

    var $j = jQuery;

    In your theme you should tell WP that you need jQuery by using the following code (don’t add the <script> tag in your header):

    <?php
function my_scripts_method() {
    wp_enqueue_script( 'jquery' );
}

add_action( 'wp_enqueue_scripts', 'my_scripts_method' );
?>

    For the script that is to use jQuery do the following:

    <script language="javascript" type="text/javascript">
jQuery(document).ready(function($) {

});
</script>

    In WordPress you have to call jQuery by name. The (4) allows you to use the $ shortcut within the confines of this call.
