Why does this dropdown show 2 March and no February?

Why does this drop down show March twice and February not at all? Thanks

PHP Code:


		
			
public function index($name=NULL) 

            {

                $CI =& get_instance();

                $CI->posted_month = $CI->input->post($name) ? $CI->input->post($name) : "";

                $m = 0;

                $CI->dropdown="<select name=\"".$name."\">";

                while($m<12)

                    {

                        $m++;

                        $CI->dropdown.="<option value=\"".$m."\"";

                        if($CI->posted_month==$m)

                            {

                                $CI->dropdown.="selected=\"selected\"";

                            }

                        $CI->dropdown.= ">\n".date("F", mktime(0, 0, 0, $m))."</option>";

                    }

                $CI->dropdown.="</select>";    

                return $CI->dropdown;

            }

Send a message via Google Talk to requinix

Because you told mktime() to create a date for the 30th of February.

Pass in 1 for the day too.

Hi,

I'd consider switching to the DateTime class, which is less low-level and easier to use:

PHP Code:


		
			
 $aux_date = new DateTime('2013-1-1');

for ($i = 1; $i <= 12; $i++) {

    echo $aux_date->format('F');

    $aux_date->modify('+1 month');

}

Here's one I use which submit onChange, holds its value, and starts with current month selected.

PHP Code:


		
			
<select name="mo" onChange="this.form.submit()">

<?php

          $current_date = getdate();

          for($i = 1; $i <= 12; $i++) {

            $selected = (isset($_POST['mo']) && $_POST['mo'] == $i) || (!isset($_POST['mo']) && $i == $current_date['mon']);

            $year = ($i <= $current_date['mon'] ? date("Y") : date("Y") - 1);

            echo '        <option value="' . $i  . '"' . ($selected ? ' selected="selected"' : '') . '>' . date("F", mktime(0, 0, 0, $i, 10)) . ' - ' . $year . '</option>\n';

          }

        ?>

      </select>
