如何使用codeigniter將CSV導入到mysql

我有一個csv文件的列表，我想使用codeigniter將其導入到mysql數據庫中。如何使用codeigniter將CSV導入到mysql

我試過$this->load->library('getcsv');庫，但是如何導入csv而不需要上傳CSV文件到服務器，我的意思是上傳文件到一個臨時位置，比如PHP的純代碼。

有什麼想法？

例子：

我想是這樣的。

HTML：<input type="file" name="csv" />

到一個臨時串

笨：$this->input->upload['tmp_name']

我給確切答案此。看看我的這個問題解決方案的答案。

這將生成CSV格式的報告。

Reports in Codeigniter

，這將告訴你如何閱讀和傾倒的CSV文件。

您的解決方案似乎很好，但是如何將CSV上傳到臨時位置等並使用它？ – 2013-04-10 16:34:28

爲此，您將不得不使用文件上傳 – 2013-04-10 19:24:21

試試這個：

數據庫：

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; 

} 

?>

        '".addslashes($data[1])."', 
        '".addslashes($data[2])."' 
       ) 
      "); 
     } 
    } while ($data = fgetcsv($handle,1000,",","'"));

首先更改route.php的default_controller值處於內部配置夾。

$ route ['default_controller'] =「csv」;

創建一個控制器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'); 
    } 
} 
?>

，並創建一個模型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; 
    } 
}

，最後創建一個視圖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>

，創造，其中數據將被插入MySQL表：

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

而且最重要的一點：

的MySQL和CSV文件都應該是相同的
