Question

我有一个csv文件列表，我希望使用codeigniter将其导入mysql db。

我尝试了$this->load->library('getcsv');库，但是如何在不将CSV文件上传到服务器的情况下导入csv，我的意思就是将文件上传到临时位置，就像纯PHP编码一样。

有什么想法吗？

示例：

我想要这样的东西。

HTML： <input type="file" name="csv" />

到临时字符串

Codeigniter： $this->input->upload['tmp_name']

Answer 1

我给出了完全答案。看看我的答案，找出你的问题的解决方案。

这将生成CSV格式的报告。

这将告诉您如何读取和转储csv文件。

Answer 2

试试这个：

数据库：

SET FOREIGN_KEY_CHECKS=0;
DROP TABLE IF EXISTS `contacts`;
CREATE TABLE `contacts` (
  `contact_id` int(11) NOT NULL auto_increment,
  `contact_first` varchar(255) character set latin1 default NULL,
  `contact_last` varchar(255) character set latin1 default NULL,
  `contact_email` varchar(255) character set latin1 default NULL,
  PRIMARY KEY  (`contact_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

import.php ::

<?php  

//connect to the database 
$connect = mysql_connect("localhost","username","password"); 
mysql_select_db("mydatabase",$connect); //select the table 
// 

if ($_FILES[csv][size] > 0) { 

    //get the csv file 
    $file = $_FILES[csv][tmp_name]; 
    $handle = fopen($file,"r"); 

    //loop through the csv file and insert into database 
    do { 
        if ($data[0]) { 
            mysql_query("INSERT INTO contacts (contact_first, contact_last, contact_email) VALUES 
                ( 
                    '".addslashes($data[0])."', 
                    '".addslashes($data[1])."', 
                    '".addslashes($data[2])."' 
                ) 
            "); 
        } 
    } while ($data = fgetcsv($handle,1000,",","'")); 
    // 

    //redirect 
    header('Location: import.php?success=1'); die; 

} 

?>

    } while ($data = fgetcsv($handle,1000,",","'"));

首先更改位于config文件夹中的route.php中的default_controller值。

$ route [＆＃39; default_controller＆＃39;] =＆＃34; csv＆＃34;;

将控制器创建为 csv.php

<?php
class csv extends CI_Controller
{
    public $data;
    public function __construct()
    {
        parent::__construct();
        $this->load->model('csv_model');
    }
    function index()
    {
        $this->load->view('uploadCsvView',$data);
    }
    function uploadData()
    {
        $this->csv_model->uploadData();
        redirect('csv');
    }
}
?>

将模型创建为 csv_model.php

<?php
class csv_model extends CI_Model
{
    function __construct()
    {
        parent::__construct();
    }
    function uploadData()
    {
        $count=0;
        $fp = fopen($_FILES['userfile']['tmp_name'],'r') or die("can't open file");
        while($csv_line = fgetcsv($fp,1024))
        {
            $count++;
            if($count == 1)
            {
                continue;
            }//keep this if condition if you want to remove the first row
            for($i = 0, $j = count($csv_line); $i < $j; $i++)
            {
                $insert_csv = array();
                $insert_csv['id'] = $csv_line[0];//remove if you want to have primary key,
                $insert_csv['empName'] = $csv_line[1];
                $insert_csv['empAddress'] = $csv_line[2];

            }
            $i++;
            $data = array(
                'id' => $insert_csv['id'] ,
                'empName' => $insert_csv['empName'],
                'empAddress' => $insert_csv['empAddress'],
            $data['crane_features']=$this->db->insert('tableName', $data);
        }
        fclose($fp) or die("can't close file");
        $data['success']="success";
        return $data;
    }
}

最后创建一个视图 uploadCsvView.php

<form action="<?php echo site_url();?>csv/uploadData" method="post" enctype="multipart/form-data" name="form1" id="form1"> 
    <table>
        <tr>
            <td> Choose your file: </td>
            <td>
                <input type="file" class="form-control" name="userfile" id="userfile"  align="center"/>
            </td>
            <td>
                <div class="col-lg-offset-3 col-lg-9">
                    <button type="submit" name="submit" class="btn btn-info">Save</button>
                </div>
            </td>
        </tr>
    </table> 
</form>

创建要插入数据的mysql表：

CREATE TABLE tableName(
    id INT,
    empName VARCHAR( 100 ) ,
    empAddress VARCHAR( 100 ),
    PRIMARY KEY (id)
)

最重要的一点：

MySql和Csv文件应该都是相同的
