如何在codeigniter中验证数组值

Question

我有自己的工作经验,可以通过输入动态添加组织名称,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:

<?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");

它不允许我提交表格,因为它需要持续时间作为强制性而不是.

我该如何解决？

欢迎任何帮助/建议.谢谢.

Answer 1

因此,正如@Hashem Qolami所建议的,我在代码中做了以下更改,并且它有效.

$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."]");
  }

Answer 2

It doesn't let me submit the form 如果是这样，这听起来像个错误。

您可以临时检查duration[]数组是否为empty：

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

如果找到主要解决方案，我将更新答案。

更新： 这是我所期望的错误，我在CodeIgniter存储库中打开了PR，可以解决此问题。
