| <h1>Calendaring Class</h1> | |
| <p>The Calendar class enables you to dynamically create calendars. Your calendars can be formatted through the use of a calendar | |
| template, allowing 100% control over every aspect of its design. In addition, you can pass data to your calendar cells.</p> | |
| <h2>Initializing the Class</h2> | |
| <p>Like most other classes in Code Igniter, the Calendar class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p> | |
| <code>$this->load->library('calendar');</code> | |
| <p>Once loaded, the Calendar object will be available using: <dfn>$this->calendar</dfn></p> | |
| <h2>Displaying a Calendar</h2> | |
| <p>Here is a very simple example showing how you can display a calendar:</p> | |
| <code>$this->load->library('calendar');<br /> | |
| <br /> | |
| echo $this->calendar->generate();</code> | |
| <p>The above code will generate a calendar for the current month/year based on your server time. | |
| To show a calendar for a specific month and year you will pass this information to the calendar generating function:</p> | |
| <code>$this->load->library('calendar');<br /> | |
| <br /> | |
| echo $this->calendar->generate(<kbd>2006</kbd>, <kbd>6</kbd>);</code> | |
| <p>The above code will generate a calendar showing the month of June in 2006. The first parameter specifies the year, the second parameter specifies the month.</p> | |
| <h2>Passing Data to your Calendar Cells</h2> | |
| <p>To add data to your calendar cells involves creating an associative array in which the keys correspond to the days | |
| you wish to populate and the array value contains the data. The array is passed to the third parameter of the calendar | |
| generating function. Consider this example:</p> | |
| <code>$this->load->library('calendar');<br /> | |
| <br /> | |
| $data = array(<br /> | |
| 3 => 'http://your-site.com/news/article/2006/03/',<br /> | |
| 7 => 'http://your-site.com/news/article/2006/07/',<br /> | |
| 13 => 'http://your-site.com/news/article/2006/13/',<br /> | |
| 26 => 'http://your-site.com/news/article/2006/26/'<br /> | |
| );<br /> | |
| <br /> | |
| echo $this->calendar->generate(<kbd>2006</kbd>, <kbd>6</kbd>, <var>$data</var>);</code> | |
| <p>Using the above example, day numbers 3, 7, 13, and 26 will become links pointing to the URLs you've provided.</p> | |
| <p class="important"><strong>Note:</strong> By default it is assumed that your array will contain links. | |
| In the section that explains the calendar template below you'll see how you can customize | |
| how data passed to your cells is handled so you can pass different types of information.</p> | |
| <h2>Setting Display Preferences</h2> | |
| <p>There are seven preferences you can set to control various aspects of the calendar. Preferences are set using an initialization | |
| function similar to other classes. Here is an example: | |
| <code>$this->load->library('calendar');<br /> | |
| <br /> | |
| $prefs = array (<br /> | |
| 'start_day' => 'saturday',<br /> | |
| 'month_type' => 'long',<br /> | |
| 'day_type' => 'short'<br /> | |
| );<br /> | |
| <br /> | |
| $this->calendar->initialize($prefs);<br /> | |
| <br /> | |
| echo $this->calendar->generate();</code> | |
| <p>The above code would start the calendar on saturday, use the "long" month heading, and the "short" day names. More information | |
| regarding preferences below.</p> | |
| <table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder"> | |
| <tr> | |
| <th>Preference</th> | |
| <th>Default Value</th> | |
| <th>Options</th> | |
| <th>Description</th> | |
| </tr><tr> | |
| <td class="td"><strong>template</strong></td><td class="td">None</td><td class="td">None</td><td class="td">A string containing your calendar template. See the template section below.</td> | |
| </tr><tr> | |
| <td class="td"><strong>local_time</strong></td><td class="td">time()</td><td class="td">None</td><td class="td">A Unix timestamp corresponding to the current time.</td> | |
| </tr><tr> | |
| <td class="td"><strong>start_day</strong></td><td class="td">sunday</td><td class="td">Any week day (sunday, monday, tuesday, etc.)</td><td class="td">Sets the day of the week the calendar should start on.</td> | |
| </tr><tr> | |
| <td class="td"><strong>month_type</strong></td><td class="td">long</td><td class="td">long, short</td><td class="td">Determines what version of the month name to use in the header. long = January, short = Jan.</td> | |
| </tr><tr> | |
| <td class="td"><strong>day_type</strong></td><td class="td">abr</td><td class="td">long, short, abr</td><td class="td">Determines what version of the weekday names to use in the column headers. long = Sunday, short = Sun, abr = Su.</td> | |
| </tr><tr> | |
| <td class="td"><strong>show_next_prev</strong></td><td class="td">FALSE</td><td class="td">TRUE/FALSE (boolean)</td><td class="td">Determines whether to display links allowing you to toggle to next/previous months. See information on this feature below.</td> | |
| </tr><tr> | |
| <td class="td"><strong>next_prev_url</strong></td><td class="td">None</td><td class="td">A URL</td><td class="td">Sets the basepath used in the next/previous calendar links.</td> | |
| </tr> | |
| </table> | |
| <h2>Creating a Calendar Template</h2> | |
| <p>By creating a calendar template you have 100% control over the design of your calendar. Each component of your | |
| calendar will be placed within a pair of pseudo-variables as shown here:</p> | |
| <code>$this->load->library('calendar');<br /><br /> | |
| $prefs['template'] = '<br /><br /> | |
| <dfn>{table_open}</dfn><var><table border="0" cellpadding="0" cellspacing="0"></var><dfn>{/table_open}</dfn><br /> | |
| <br /> | |
| <dfn>{heading_row_start}</dfn><var><tr></var><dfn>{/heading_row_start}</dfn><br /> | |
| <br /> | |
| <dfn>{heading_previous_cell}</dfn><var><th><a href="</var><kbd>{previous_url}</kbd><var>">&lt;&lt;</a></th></var><dfn>{/heading_previous_cell}</dfn><br /> | |
| <dfn>{heading_title_cell}</dfn><var><th colspan="</var><kbd>{colspan}</kbd><var>"></var><kbd>{heading}</kbd><var></th></var><dfn>{/heading_title_cell}</dfn><br /> | |
| <dfn>{heading_next_cell}</dfn><var><th><a href="</var><kbd>{next_url}</kbd><var>">&gt;&gt;</a></th></var><dfn>{/heading_next_cell}</dfn><br /> | |
| <br /> | |
| <dfn>{heading_row_end}</dfn><var></tr></var><dfn>{/heading_row_end}</dfn><br /> | |
| <br /> | |
| <dfn>{week_row_start}</dfn><var><tr></var><dfn>{/week_row_start}</dfn><br /> | |
| <dfn>{week_day_cell}</dfn><var><td></var><dfn>{week_day}</dfn><var></td></var><dfn>{/week_day_cell}</dfn><br /> | |
| <dfn>{week_row_end}</dfn><var></tr></var><dfn>{/week_row_end}</dfn><br /> | |

| <dfn>{cal_row_start}</dfn><var><tr></var><dfn>{/cal_row_start}</dfn><br /> | |
| <dfn>{cal_cell_start}</dfn><var><td></var><dfn>{/cal_cell_start}</dfn><br /> | |

| <dfn>{cal_cell_content_today}</dfn><var><div class="highlight"><a href="</var><kbd>{content}</kbd><var>"></var><kbd>{day}</kbd><var></a></div></var><dfn>{/cal_cell_content_today}</dfn><br /> | |

| <dfn>{cal_cell_no_content_today}</dfn><var><div class="highlight"></var><kbd>{day}</kbd><var></div></var><dfn>{/cal_cell_no_content_today}</dfn><br /> | |
| <br /> | |
| <dfn>{cal_cell_blank}</dfn><var>&nbsp;</var><dfn>{/cal_cell_blank}</dfn><br /> | |
| <br /> | |
| <dfn>{cal_cell_end}</dfn><var></td></var><dfn>{/cal_cell_end}</dfn><br /> | |
| <dfn>{cal_row_end}</dfn><var><tr></var><dfn>{/cal_row_end}</dfn><br /> | |
| <br /> | |
| <dfn>{table_close}</dfn><var></table></var><dfn>{/table_close}</dfn><br /> | |
| ';<br /> | |
| <br /> | |
| $this->calendar->initialize($prefs);<br /> | |
| <br /> | |
| echo $this->calendar->generate();</code> | |
| <h2>Showing Next/Previous Month Links</h2> | |
| <p>To allow your calendar to dynamically increment/decrement via the next/previous links requires that you set up your calendar | |
| code similar to this example:</p> | |
| <code>$this->load->library('calendar');<br /> | |
| <br /> | |
| $prefs = array (<br /> | |
| 'show_next_prev' => TRUE,<br /> | |
| 'next_prev_url' => 'http://www.your-site.com/index.php/calendar/show/'<br /> | |
| );<br /> | |
| <br /> | |
| $this->calendar->initialize($prefs);<br /> | |
| <br /> | |
| echo $this->calendar->generate(<var>$this->uri->segment(3)</var>, <var>$this->uri->segment(4)</var>);</code> | |
| <p>You'll notice a few things about the above example:</p> | |
| <ul> | |
| <li>You must set the "show_next_prev" to TRUE.</li> | |
| <li>You must supply the URL to the controller containing your calendar in the "next_prev_url" preference.</li> | |
| <li>You must supply the "year" and "month" to the calendar generating function via the URI segments where they appear (Note: The calendar class automatically adds the year/month to the base URL you provide.).</li> | |
| </ul> | |
