如何在codeigniter中验证数组值

Question

我的表单工作经验是动态添加的，输入为组织名称、部门名称、职位和持续时间。

<tr>
    <td><span class="serial_no">1</span></td>
    <td><input type="text" name="organization[]" size="50"/></td>
    <td><input type="text" name="department[]" size="50"></td>
    <td><input type="text" name="positions[]" size="40"></td>
    <td><input type="text" name="duration[]"></td>
</tr>

在 CI 中进行验证时，我执行了以下操作：

$organization = $this->input->post('organization');
$department   = $this->input->post('department');
$positions    = $this->input->post('positions');
$duration     = $this->input->post('duration');

//printr($organization);
for($i = 0; $i < count($organization); $i++) 
{
    $org = $organization[$i];
    $dept = $department[$i];
    $pos = $positions[$i];
    $dura = $duration[$i];

    $this->form_validation->set_rules($org, "Organization", "trim|xss_clean|max_length[1]");
    $this->form_validation->set_rules($dept, "Department", "trim|xss_clean|max_length[50]");
    $this->form_validation->set_rules($pos, "Position", "trim|xss_clean|max_length[40]");
    $this->form_validation->set_rules($dura, "Duration", "trim|xss_clean|integer");
}

并显示错误为：

<?php
    echo form_error("organization[]");
    echo form_error("department[]"); 
    echo form_error("positions[]"); 
    echo form_error("duration[]");
?> 

现在的问题是它不会将持续时间验证为整数。即使我放了一些随机的字母字符，它也不会显示错误。

当我验证如下：

$this->form_validation->set_rules('organization[]', "Organization", "trim|xss_clean|max_length[50]");
$this->form_validation->set_rules('department[]', "Department", "trim|xss_clean|max_length[50]");
$this->form_validation->set_rules('positions[]', "Position", "trim|xss_clean|max_length[40]");
$this->form_validation->set_rules('duration[]',"Duration", "trim|xss_clean|numeric");

它不允许我提交表单，因为它需要持续时间，但它不是。

我该如何解决？

欢迎任何帮助/建议。谢谢。

Answer 1

It doesn't let me submit the form 如果是这样，那听起来像是一个错误。

暂时可以检查duration[]数组是否为empty：

if (! empty($_POST['duration'])) {
    $this->form_validation->set_rules('duration[]',"Duration", "trim|xss_clean|numeric");
}

如果我找到主要解决方案，我会更新我的答案。

更新： 正如我所料，这是一个错误，我在 CodeIgniter 存储库opened a PR，可以解决这个问题。

Answer 2

按照@Hashem Qolami 的建议，我对我的代码进行了以下更改，并且成功了。

$organization    = $this->input->post('organization');
$department      = $this->input->post('department');
$positions       = $this->input->post('positions');
$duration        = $this->input->post('duration');

foreach($organization as $ind=>$val) 
{
    $org  = $organization[$ind];
    $dept = $department[$ind];
    $pos  = $positions[$ind];
    $dura = $duration[$ind];

    $this->form_validation->set_rules("organization[".$ind."]", "Organization", "trim|xss_clean|max_length[1]");
    $this->form_validation->set_rules("department[".$ind."]", "Department", "trim|xss_clean|max_length[50]");
    $this->form_validation->set_rules("positions[".$ind."]", "Position", "trim|xss_clean|max_length[40]");
    if(!empty($dura))
       $this->form_validation->set_rules("duration[".$ind."]", "Duration", "trim|xss_clean|integer");
}

并显示我的错误如下

 for($i = 0; $i < count($organization); $i++) {
     echo form_error("organization[".$i."]"); 
     echo form_error("department[".$i."]"); 
     echo form_error("positions[".$i."]"); 
     echo form_error("duration[".$i."]");
  }
