如何在codeigniter中验证数组值 [英] how to validate array value in codeigniter

问题描述

我的工作经验是动态添加的，输入组织名称、部门名称、职位和持续时间.

I have in my form work experience which is added dynamically with input as organisation name, department name, position and duration.

<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:

While validating in CI I did the following:

$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[]");
?> 

现在的问题是它没有将持续时间验证为整数.即使我输入了一些随机的字母字符，它也不会显示错误.

Now the problem is it doesn't validate the duration as integer. Even if I put some random alpha characters it doesn't show errors.

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作为强制性的，而事实并非如此.

It doesn't let me submit the form as it takes duration as mandatory which it isn't.

我该如何解决?

欢迎任何帮助/建议.谢谢.

any help/suggestions are welcome. thanks.

推荐答案

它不允许我提交表单 如果是这样，这听起来像是一个错误.

It doesn't let me submit the form If so, It sounds like a bug.

暂时可以检查duration[]数组是否为empty:

Temporarily, you can check whether duration[] array is empty or not:

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

如果找到主要解决方案，我会更新我的答案.

I'll update my answer if I found the main solution.

更新:正如我所料，这是一个错误，我在 CodeIgniter 存储库打开了一个 PR，这将修复这个问题.

Update: This is a bug as I expected, I opened a PR at CodeIgniter Repository, that would fix this issue.
