| 64 | <h1>Cookie Helper</h1>
|
| 65 |
|
| 66 | <p>The Cookie Helper file contains functions that assist in working with cookies.</p>
|
| 67 |
|
| 68 |
|
| 69 | <h2>Loading this Helper</h2>
|
| 70 |
|
| 71 | <p>This helper is loaded using the following code:</p>
|
| 72 | <code>$this->load->helper('cookie');</code>
|
| 73 |
|
| 74 | <p>The following functions are available:</p>
|
| 75 |
|
| 76 | <h2>set_cookie()</h2>
|
| 77 |
|
| 78 | <p>Sets a cookie containing the values you specify. There are two ways to pass information this function so that a cookie can be set:
|
| 79 | Arrray Method, and Discreet Parameters:</p>
|
| 80 |
|
| 81 | <h4>Array Method</h4>
|
| 82 |
|
| 83 | <p>Using this method, an associative array is passed to the first parameter:</p>
|
| 84 |
|
| 85 | <code>$cookie = array(<br />
|
| 86 | 'name' => 'The Cookie Name',<br />
|
| 87 | 'value' => 'The Value',<br />
|
| 88 | 'expire' => '86500',<br />
|
| 89 | 'domain' => '.some-domain.com',<br />
|
| 90 | 'path' => '/',<br />
|
| 91 | 'prefix' => 'myprefix_',<br />
|
| 92 | );<br />
|
| 93 | <br />
|
| 94 | set_cookie($cookie);
|
| 95 | </code>
|
| 96 |
|
| 97 | <p><strong>Notes:</strong></p>
|
| 98 |
|
| 99 | <p>Only the name and value are required.</p>
|
| 100 |
|
| 101 | <p>The expiration is set in <strong>seconds</strong>, which will be added to the current time. Do not include the time, but rather only the
|
| 102 | number of seconds from <em>now</em> that you wish the cookie to be valid. If the expiration is set to
|
| 103 | zero the cookie will only last as long as the browser is open.</p>
|
| 104 | <p>To delete a cookie set it with the expiration blank.</p>
|
| 105 | <p>For site-wide cookies regardless of how your site is requested, add your URL to the <strong>domain</strong> starting with a period, like this: .your-domain.com</p>
|
| 106 | <p>The path is usually not needed since the function sets a root path.</p>
|
| 107 | <p>The prefix is only needed if you need to avoid name collisions with other identically named cookies for your server.</p>
|
| 108 |
|
| 109 | <h4>Discreet Parameters</h4>
|
| 110 |
|
| 111 | <p>If you prefer, you can set the cookie by passing data using individual parameters:</p>
|
| 112 |
|
| 113 | <code>set_cookie($name, $value, $expire, $domain, $path, $prefix);</code>

| 114 |
