59<h1>Cookie Helper</h1>
60
61<p>The Cookie Helper file contains functions that assist in working with cookies.</p>
62
63
64<h2>Loading this Helper</h2>
65
66<p>This helper is loaded using the following code:</p>
67<code>$this->load->helper('cookie');</code>
68
69<p>The following functions are available:</p>
70
71<h2>set_cookie()</h2>
72
73<p>Sets a cookie containing the values you specify. There are two ways to pass information this function so that a cookie can be set:
admin885b0342006-09-21 05:36:15 +0000[diff] [blame]74Array Method, and Discreet Parameters:</p>
adminb0dd10f2006-08-25 17:25:49 +0000[diff] [blame]75
76<h4>Array Method</h4>
77
78<p>Using this method, an associative array is passed to the first parameter:</p>
79
80<code>$cookie = array(<br />
81&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'name'&nbsp;&nbsp;&nbsp;=> 'The Cookie Name',<br />
82&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'value'&nbsp;&nbsp;=> 'The Value',<br />
83&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'expire' => '86500',<br />
84&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'domain' => '.some-domain.com',<br />
85&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'path'&nbsp;&nbsp;&nbsp;=> '/',<br />
86&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'prefix' => 'myprefix_',<br />
87&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
88<br />
89set_cookie($cookie);
90</code>
91
92<p><strong>Notes:</strong></p>
93
94<p>Only the name and value are required.</p>
95
96<p>The expiration is set in <strong>seconds</strong>, which will be added to the current time. Do not include the time, but rather only the
admine334c472006-10-21 19:44:22 +0000[diff] [blame]97number of seconds from <em>now</em> that you wish the cookie to be valid. If the expiration is set to
adminb0dd10f2006-08-25 17:25:49 +0000[diff] [blame]98zero the cookie will only last as long as the browser is open.</p>
99<p>To delete a cookie set it with the expiration blank.</p>
100<p>For site-wide cookies regardless of how your site is requested, add your URL to the <strong>domain</strong> starting with a period, like this: .your-domain.com</p>
101<p>The path is usually not needed since the function sets a root path.</p>
102<p>The prefix is only needed if you need to avoid name collisions with other identically named cookies for your server.</p>
103
104<h4>Discreet Parameters</h4>
105
106<p>If you prefer, you can set the cookie by passing data using individual parameters:</p>
107
108<code>set_cookie($name, $value, $expire, $domain, $path, $prefix);</code>
109
admin885b0342006-09-21 05:36:15 +0000[diff] [blame]110<h2>get_cookie()</h2>
111
112<p>Lets you fetch a cookie. The first parameter will contain the name of the cookie you are looking for:</p>
113
114<code>get_cookie('some_cookie');</code>
115
116<p>The function returns FALSE (boolean) if the item you are attempting to retrieve does not exist.</p>
117
118<p>The second optional parameter lets you run the data through the XSS filter. It's enabled by setting the second parameter to boolean TRUE;</p>
119
120<code>get_cookie('some_cookie', TRUE);</code>
121
122
123
124<h2>delete_cookie()</h2>
125
126<p>Lets you delete a cookie. Unless you've set a custom path or other values, only the name of the cookie is needed:</p>
127
128<code>delete_cookie("name");</code>
129
admine334c472006-10-21 19:44:22 +0000[diff] [blame]130<p>This function is otherwise identical to <dfn>set_cookie()</dfn>, except that it does not have the value and expiration parameters. You can submit an array
admin885b0342006-09-21 05:36:15 +0000[diff] [blame]131of values in the first parameter or you can set discreet parameters.</p>
132
133<code>delete_cookie($name, $domain, $path, $prefix)</code>
