| <h1>Cookie Helper</h1> | |
| <p>The Cookie Helper file contains functions that assist in working with cookies.</p> | |
| <h2>Loading this Helper</h2> | |
| <p>This helper is loaded using the following code:</p> | |
| <code>$this->load->helper('cookie');</code> | |
| <p>The following functions are available:</p> | |
| <h2>set_cookie()</h2> | |
| <p>Sets a cookie containing the values you specify. There are two ways to pass information this function so that a cookie can be set: | |
| Arrray Method, and Discreet Parameters:</p> | |
| <h4>Array Method</h4> | |
| <p>Using this method, an associative array is passed to the first parameter:</p> | |
| <code>$cookie = array(<br /> | |
| 'name' => 'The Cookie Name',<br /> | |
| 'value' => 'The Value',<br /> | |
| 'expire' => '86500',<br /> | |
| 'domain' => '.some-domain.com',<br /> | |
| 'path' => '/',<br /> | |
| 'prefix' => 'myprefix_',<br /> | |
| );<br /> | |
| <br /> | |
| set_cookie($cookie); | |
| </code> | |
| <p><strong>Notes:</strong></p> | |
| <p>Only the name and value are required.</p> | |
| <p>The expiration is set in <strong>seconds</strong>, which will be added to the current time. Do not include the time, but rather only the | |
| number of seconds from <em>now</em> that you wish the cookie to be valid. If the expiration is set to | |
| zero the cookie will only last as long as the browser is open.</p> | |
| <p>To delete a cookie set it with the expiration blank.</p> | |
| <p>For site-wide cookies regardless of how your site is requested, add your URL to the <strong>domain</strong> starting with a period, like this: .your-domain.com</p> | |
| <p>The path is usually not needed since the function sets a root path.</p> | |
| <p>The prefix is only needed if you need to avoid name collisions with other identically named cookies for your server.</p> | |
| <h4>Discreet Parameters</h4> | |
| <p>If you prefer, you can set the cookie by passing data using individual parameters:</p> | |
| <code>set_cookie($name, $value, $expire, $domain, $path, $prefix);</code> | |
