如何验证codeigniter中的数组值 [英] how to validate array value in codeigniter

问题描述

我的表单工作经验是以组织名称，部门名称，职位和持续时间等动态输入。

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

在CI中验证时，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：

$ b b

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

现在问题是它不会将持续时间验证为整数。

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，因为它需要的持续时间是强制性的，而不是。

如何解决？

欢迎任何帮助/建议。感谢。

解决方案

它不允许我提交表单 If所以，它听起来像一个错误。

暂时，你可以检查 duration [] $ c> empty 或不：

  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。 >

更新：
这是我预期的错误，我在CodeIgniter存储库中打开了PR ，这将解决这个问题。

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>

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");
}

And displayed error as:

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

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.

When I validate as follows:

$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");

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

How do I solve it?

any help/suggestions are welcome. thanks.

解决方案

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

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");
}

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

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