Question

我正在使用codeigniter.I将税务详细信息存储在会话值中，以存储税是包含税还是独占税。我需要使用strstr()检查字符串值并进行一些计算。我做了下面的计算

<?php 
     $tax_percentage=$tax['company_tax13'];
    if(strstr($service_detail['service_tax'],"inclusive")==true) {
    $taxamount=$service_detail['service_price']-($service_detail['service_price']/(1+($tax_percentage/100)));
    $grand=$service_detail['service_price'];
    }
    else {
    $taxamount=($service_detail['service_price']*(1+($tax_percentage/100)))-$service_detail['service_price'];
    $grand=$taxamount+$service_detail['service_price'];
    }
    ?>

运行代码时我的控制器的响应是

Array ( [service_detail] => Array ( [service_price] => 1000 [service_tax] =>"inclusive" ) [tax] => Array ( [0] => Array ( [company_tax13] => 14 ) ) )

我怎么能为此编码。代码有问题吗？我的控制器文件。这里我有一个存储service_detail['service_tax']

的会话变量

 public function add()
    {
        //if save button was clicked, get the data sent via post
        if ($this->input->server('REQUEST_METHOD') === 'POST')
        {
$this->load->library('session');
            $this->session->unset_userdata('service_detail');
            //if the form has passed through the validation
            if ($this->form_validation->run())
            {
                $data_to_store = array(
                'id' => $this->input->post('id'),
                    'service_name' => $this->input->post('service_name'),
                    'category' => $this->input->post('category'),
                    'service_tax' => $this->input->post('service_tax'),
                    'service_length' => $this->input->post('service_length'),          
                    'service_price' => $this->input->post('service_price')
                );
                //if the insert has returned true then we show the flash message
                if($this->service_model->store_service($data_to_store)){
                    $data['flash_message'] = TRUE; 
                    $this->session->set_flashdata('flash_message', 'updated');
                    $this->session->set_userdata('service_detail', ['service_price'=>$this->input->post('service_price'),'service_tax'=>$this->input->post('service_tax')]);
                    redirect(base_url().'admin/service/view');
                }else{
                    $data['flash_message'] = FALSE; 
                }

            }

        }
        $data['category'] = $this->category_model->get_category();
        $data['main_content'] = 'admin/service/add';
        $this->load->view('includes/template', $data);  
    }

Answer 1

如果您的参数始终为inclusive / exclusive，请使用开关：

switch (strtolower($service_detail['service_tax']))
{
    case 'inclusive':
        //do your stuff;
        break;

    case 'exclusive':
        //do your stuff;
        break;
}

Answer 2

在视图中，$ data数组的键被转换为变量，因此请尝试var_dump($somekey)。这是通过extract完成的。

您还可以将strstr更改为strcmp甚至===（因为您不关心哪个字符串更大）。

if(strtolower($service_detail['service_tax']) === "inclusive")

或

if(strcmp(strtolower($service_detail['service_tax']), "inclusive"))

需要更多关于strstr（）的知识。它对我不起作用
