I'm getting a strange behaviour from form_dropdown - basically, when I reload the page after validation, the values are screwed up.
this bit generates 3 drop downs with days, months and years:
$days = array(0 => 'Day...');
for ($i = 1; $i <= 31; $i++)
{
$days[] = $i;
}
$months = array(0 => 'Month...', );
for ($i = 1; $i <= 12; $i++)
{
$months[] = $i;
}
$years = array(0 => 'Year...');
for ($i = 2010; $i <= 2012; $i++)
{
$years[$i] = $i;
echo "<pre>"; print_r($years); echo "</pre>";//remove this
}
$selected_day = (isset($selected_day)) ? $selected_day : 0;
$selected_month = (isset($selected_month)) ? $selected_month : 0;
$selected_year = (isset($selected_year)) ? $selected_year : 0;
echo "<p>";
echo form_label('Select date:', 'day', array('class' => 'left'));
echo form_dropdown('day', $days, $selected_day, 'class="combosmall"');
echo form_dropdown('month', $months, $selected_month, 'class="combosmall"');
echo form_dropdown('year', $years, $selected_year, 'class="combosmall"');
echo "</p>";
...and generates this:
<p><label for="day" class="left">Select date:</label><select name="day" class="combosmall">
<option value="0" selected="selected">Day...</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
<option value="13">13</option>
<option value="14">14</option>
<option value="15">15</option>
<option value="16">16</option>
<option value="17">17</option>
<option value="18">18</option>
<option value="19">19</option>
<option value="20">20</option>
<option value="21">21</option>
<option value="22">22</option>
<option value="23">23</option>
<option value="24">24</option>
<option value="25">25</option>
<option value="26">26</option>
<option value="27">27</option>
<option value="28">28</option>
<option value="29">29</option>
<option value="30">30</option>
<option value="31">31</option>
</select><select name="month" class="combosmall">
<option value="0" selected="selected">Month...</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10</option>
<option value="11">11</option>
<option value="12">12</option>
</select><select name="year" class="combosmall">
<option value="0" selected="selected">Year...</option>
<option value="2010">2010</option>
<option value="2011">2011</option>
<option value="2012">2012</option>
</select></p>
however, when the form is reloaded after validation, the same code above generates this:
<!-- days and months... -->
<select name="year" class="combosmall">
<option value="0" selected="selected">Year...</option>
<option value="1">2010</option>
<option value="2">2011</option>
<option value="3">2012</option>
</select>
So basically the value start from 1 instead
of 2010. The same happens to days and months but obviously it doesn't make any difference in this particular case as the values would start from 1 anyway.
How can I fix this - and why does it happen?
edit: validation rules are:
$this->load->library('form_validation');
//...rules for other fields..
$this->form_validation->set_rules('day', 'day', 'required|xss_clean');
$this->form_validation->set_rules('month', 'month', 'required|xss_clean');
$this->form_validation->set_rules('year', 'year', 'required|xss_clean');
$this->form_validation->set_error_delimiters('<p class="error">', '</p>');
//define other errors
if($this->input->post('day') == 0 || $this->input->post('month') == 0 || $this->input->post('year') == 0)
{
$data['error'] = "Please check the
date of your event.";
}
