WordPress function to list site cookies

Having recently reviewed the WordPress plugins that are available to assist with the current cookie legislation I was dismayed to find a lack of anything simple that would be list out the shortcodes on a site, yet provide some flexibility.

So, I’ve written something.

Add the code below to the functions.php file in your theme folder and then use the following shortcode in a post or page…

[cookies]

Simple, eh? This will list all the site’s cookies along with their values. Two further options are available…

[cookies novalue]

This will now output the cookie values.

[cookies] ==> [/cookies]

By providing a value between opening and closing shortcodes you can override the text that is used to separate the cookie name and the value.

	<?php
	function get_cookies( $paras = '', $content = '' ) {

	if ( strtolower( $paras[ 0 ] ) == 'novalue' ) { $novalue = true; } else { $novalue = false; }

	if ( $content == '' ) { $seperator = ' : '; } else { $seperator = $content; }

	$cookie = $_COOKIE;
	ksort( $cookie );

	$content = "<ul>n";
	foreach ( $cookie as $key => $val ) {
	$content .= '<li>' . $key;
	if ( !$novalue ) { $content .= $seperator . $val; }
	$content .= "</li>n";
	}
	$content .= "</ul>n";

	return do_shortcode( $content );
	}
	add_shortcode( 'cookies', 'get_cookies' );
	?>

Hello, I’ve tried the script but it shows only 3 cookies of the 8 (I’m logged in)

Thanks – some re-coding to sort out a small bug

/**
* Display a list of cookies on WordPress
*
* @param string $atts – attributes
* @param string $content

*/
function get_cookies( $atts = ”, $content = ” ) {
$atts = shortcode_atts(
array(
‘novalue’ => 0, //0 – false, 1 – true
‘separator’ => ‘ : ‘
),
$atts
);
$cookie = $_COOKIE;
ksort( $cookie );
$out = ”;
foreach ( $cookie as $key => $val ) {
$out .= ” . $key;
$out .= !$atts[‘novalue’]? $atts[‘separator’] . $val: ”;
$out .= ”;
}
$out .= ”;
return $out;
}
add_shortcode( ‘cookies’, ‘get_cookies’ );

The above code throws a syntax error: unexpected ” : “, expected ” )”. I have no idea what this means, I don’t understand php coding. Good thing I had a backup of the functions.php, it broke my site.
