How can I get post data into an array in CodeIgniter? post items are arrays
提问by TopTomato
In CodeIgniter, I'm trying to accomplish a batch update from form inputs that share the same name. But don't know how to get post data into an array. A simplified view of the form is as follows:
在 CodeIgniter 中，我试图从共享相同名称的表单输入中完成批量更新。但不知道如何将发布数据放入数组。表格的简化视图如下：
<input name="id[]" value="1"/><input name = title[] value="some-title"/><input name ="sort_order[]" value="1"/>
<input name="id[]" value="2"/><input name = title[] value="some-tuttle"/><input name="sort_order[]" value="2"/>
<input name="id[]" value="3"/><input name = title[] value="some-turtle"/><input name="sort_order[]" value="3"/>
In my controller I have this for now:
在我的控制器中，我现在有这个：
function set_sort_order(){
$data = array(
array('id' => 1,'sort_order' => 14),
array('id' => 2,'sort_order' => 5),
array('id' => 3,'sort_order' => 9)
);
$this->db->update_batch('press_releases', $data, 'id');//works!
$this->load->view(pr_listing);
}
The array is hard-wired to test in the input_batch function, which is working. So how can I get the post data into an array?
该数组是硬连线以在 input_batch 函数中进行测试，该函数正在工作。那么如何将帖子数据放入数组中呢？

$id = $this->input->post('id');
$sort_order = $this->input->post('sort_order');
$data = array();
foreach($id as $key=>$val)
{
$data[] = array('id'=>$val,'sort_order'=>$sort_order[$key]);
}

Just by nature of the way the input fields are named using bracket notation (i.e. fieldname[]) will cause PHP to automatically populate data from these fields into an array. Simple access them like:
根据输入字段的命名方式，使用方括号表示法（即fieldname[]）会导致 PHP 自动将这些字段中的数据填充到数组中。简单访问它们，如：
$ids = $_POST['id'];
$titles = $_POST['title'];
// etc.
You can easily combine these into a multidimensional array
您可以轻松地将这些组合成一个多维数组
$final_array = array();
$length = count($ids);
for($i = 0; $i < $length; $i++) {
$final_array[$i]['id'] = $ids[$i];
$final_array[$i]['title'] = $titles[$i];
// etc.
}
var_dump($final_array);
Note: I did not show any input data validation/cleansing steps in my example. You probably want to verify input data exists, is in proper format, etc. before working with it.
注意：在我的示例中，我没有显示任何输入数据验证/清理步骤。在使用之前，您可能想要验证输入数据是否存在、格式是否正确等。
