Get Values from Multiple select Box In Codeigniter
提问by Harshal Mahajan
I have a multiple select box:
我有一个多选框：
<select name="tar[]" multiple="multiple" style="height:100px;" id="select1">
<?php foreach($lists as $list){ ?>
<option value="<?php echo $list['des_id']; ?>"><?php echo $list['designation']; ?></option>
<?php } ?>
</select>
At controller i am trying to get the values of selected fields,but failed to get that and i am getting values like 2 or 3.
在控制器上，我试图获取所选字段的值，但未能获取，我得到了 2 或 3 之类的值。
$target = $this->input->post('tar');
print_r($target);die;
Am i doing right??please guide me.Thanks.

You can also use Core PHP style,because Core PHP is the top of all framework:
你也可以使用 Core PHP 风格，因为 Core PHP 是所有框架的顶部：
if(isset($_POST['tar'])){
foreach ($_POST['tar'] as $tar_value){
print "You are selected $tar_value<br/>";
}
}
