我從form_dropdown得到一個奇怪的行爲 - 基本上,當我在驗證後重新加載頁面時,這些值被搞砸了。CodeIgniter中的form_dropdown
該位產生與天,3名月下拉列表和年:
$days = array(0 => 'Day...');
for ($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>";
...併產生這樣的:
<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>
然而,當表單驗證後重新加載,相同上面的代碼生成此:
<!-- 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>
所以基本上價值從1而不是2010開始。山姆e發生在幾天和幾個月,但顯然它在這種特殊情況下沒有任何區別,因爲值始終爲1。
我該如何解決這個問題 - 爲什麼會發生?
編輯:驗證規則是:
$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.";
}
當你說「驗證後重新加載頁面」是否意味着你正在通過表單驗證類運行它?如果是這樣,你設定了哪些驗證規則? – musoNic80 2010-04-12 17:57:18
我在上面的帖子中添加了驗證規則。 – Patrick 2010-04-12 19:14:17
