Codeigniter - 显示数组字段的单独错误消息
拥有大量客户，每个客户都有各自的详细信息。这是一个非常简单的例子。
在 codeigniter 中，每个 customer_name 都是必需的$this->form_validation->set_rules('customer_names[]','Customer Names','required');
如果任何客户名称为空，validation_errors(); 显示整个数组的一条消息。
我如何获取该客户的单独错误消息？
注意： echo form_error('customer_names[0]'); 是我试图实现的目标，其中 customer_name 0 留空。
Have array of customers each with individual details. Here is a very SIMPLE example.
<input type="text" name="customer_names[]" />
In codeigniter, each customer_name is required$this->form_validation->set_rules('customer_names[]','Customer Names','required');
If any of the customer names are blank, validation_errors(); shows one message for the entire array.
How can I obtain individual error messages for that customer?
NOTE: echo form_error('customer_names[0]'); is what I am trying to achieve where customer_name 0 was left blank.

查看表单验证文档，特别是使用数组作为字段名称部分，我认为您需要明确命名您的输入
通过在名称中包含索引以使
form_error()方法按您的意愿工作。因此，为了让
form_error('customer_names[0]')正常工作，实际上必须有一个名为customer_names[0]的输入。Looking at the Form Validation documentation, specifically the Using Arrays as Field Names section, I think you're going to need to explicitly name your inputs
by including the index in the name to get the
form_error()method to work as you desire.So in order for
form_error('customer_names[0]')to work, there will actually have to be an input with the namecustomer_names[0].我在使用 CodeIgniter 2.1.3 时遇到了同样的问题。我已经这样解决了：
输入是：
...
表单验证为：
$this->form_validation->set_rules('customer_names[0]','Customer Names','required');$this->form_validation->set_rules('customer_names[1]','客户姓名','必填');
...
错误显示如下：
echo form_error('customer_names[0]');echo form_error('customer_names[1]');
...
I was having the same problem with CodeIgniter 2.1.3. I have resolved it like this:
The input is:
<input type="text" name="customer_names[0]" /><input type="text" name="customer_names[1]" />
...
The form validation is:
$this->form_validation->set_rules('customer_names[0]','Customer Names','required');$this->form_validation->set_rules('customer_names[1]','Customer Names','required');
...
The errors are displayed like this:
echo form_error('customer_names[0]');echo form_error('customer_names[1]');
...
