按提交按钮后,我的下拉列表将清除。我尝试更改但发生错误。
<select name="staff" id="staff" required>
<option value="">Select Staff</option>
<?php while($row_subject = mysql_fetch_array($query_subject)) { ?>
<option value="<?php echo $row_subject['deo_code']; ($this->input->post('staff') == $row_subject['deo_code'] ? ' selected' : '') ?>">
<?php echo $row_subject['deo_code']."-".$row_subject['deo_name'];?>
</option>
<?php } ?>
</select>
答案 0 :(得分:-1)
您可以使用类似这样的东西:
<select name="staff" id="staff" required>
<?php for($i = 1; $i <= 10; $i++) ?>
<option value="<?php echo $i ?>" <?php $i == 2 ? 'selected' : '' ?>><?php echo $i ?< بزرگسال</option>
<option value="">Select Staff</option>
</select>
