Question

我正在尝试通过网络表单上传包含以下链接[请参阅CSV示例]中所述字段的CSV文件。用户可以通过单击上载按钮浏览他们的计算机，选择他们的CSV文件，然后单击上载，然后将CSV数据导入到相应字段的数据库中。在用户上传其CSV文件时，该行为空，并且不包含CSV文件包含的任何数据。有没有办法解决这个问题，以便CSV文件中的数据导入到数据库并放在其关联字段中？

CSV示例：

function csv_to_array($filename='', $delimiter=',')
{
    if(!file_exists($filename) || !is_readable($filename))
        return FALSE;

   $header = NULL;
   $data = array();
   if (($handle = fopen($filename, 'r')) !== FALSE)
   {
     while (($row = fgetcsv($handle, 1000, $delimiter)) !== FALSE)
     {
        if(!$header)
            $header = $row;
        else
            $data[] = array_combine($header, $row);
     }
     fclose($handle);
   }
   return $data;
}



$filedata= csv_to_array($_FILES  ['uploaded_file']['tmp_name']);

foreach($filedata as $data)
{
    $sql = "INSERT into table SET value1='".$data['value1']."'......";
}

试试这个

<?php
if(isset($_FILES['uploaded_file'])) {
    if($_FILES['uploaded_file']['error'] == 0) {
        $dbLink = new mysqli('localhost', 'root', 'vario007', 'spineless');
        if(mysqli_connect_errno()) {
            die("MySQL connection failed: ". mysqli_connect_error());
        }

        $file = $_FILES  ['uploaded_file']['tmp_name'];
        $handle = fopen($file, "r");
        $row = 1;
        while (($data = fgetcsv($handle, 0, ",","'")) !== FALSE)
        {
            if($row == 1)
            {
                // skip the first row   
            }
            else
            {
                //csv format data like this 
                //$data[0] = date
                //$data[1] = order_ref

                //$data[4] = quantity
                //$data[5] = packing_price
                //$data[6] = dispatch_type

                $query = "
                INSERT INTO `Retail` (
                `date`, `order_ref`, `postcode`, `country`, `quantity`, `packing_price`, `dispatch_type`, `created`

                VALUES (

                $result = $dbLink->query($query);


                 // Check if it was successfull
                if($result) {
                    echo 'Success! Your file was successfully added!';
                }
                else {
                    echo 'Error! Failed to insert the file'
                    . "<pre>{$dbLink->error}</pre>";
                 }
            }
            $row++;
        }



    }
    else {
        echo 'An error accured while the file was being uploaded. '
           . 'Error code: '. intval($_FILES['uploaded_file']['error']);
    }

}

// Echo a link back to the main page
echo '<p>Click <a href="welcome.php">here</a> to go back</p>';

fgetcsv()在分隔符中的第三个参数中要保存在csv文件中。例如：逗号，分号等。
