PHP公告：未定義的偏移數組文件不能上傳

Question

我已經打開這關係我的文章的所有問題，但我仍然混淆。我嘗試使用PHP導入我的csv文件。

我試試這個tutorial。但我得到這個錯誤：

PHP Notice: Undefined offset: 1 
PHP Notice: Undefined offset: 2 
PHP Notice: Undefined offset: 3 
PHP Notice: Undefined index: csv 

我已經修改到我的數據庫：

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 { 
     while ($data = fgetcsv($handle,1000,",","'")){ 
     print_r($data); 
     if ($data[0]) { 
      mysql_query("INSERT INTO prod_schedule (RecNo,  Model_Name,  Lot_Number,  Start_Serial, 
           Qty, Lot_Qty, Line, Line_Name,  Start_Date,  End_Date,  Due_Date 
         ) VALUES 
       ( 
        '".addslashes($data[0])."', 
        '".addslashes($data[1])."', 
        '".addslashes($data[2])."', 
        '".addslashes($data[3])."', 
        '".addslashes($data[4])."', 
        '".addslashes($data[5])."', 
        '".addslashes($data[6])."', 
        '".addslashes($data[7])."', 
        '".addslashes($data[8])."', 
        '".addslashes($data[9])."' 
       ) 
      "); 
     } 
    } 
//  while ($data = fgetcsv($handle,1000,",","'")); 
    // 
    //redirect 
    header('Location: upload.php?success=1'); die; 

}

的print_r（$數據）的結果是：

Array ([0] => RecNo Model_Name Lot_Number Start_Serial Qty Lot_Qty Line Line_Name Start_Date End_Date Due_Date) Array ([0] => 1 KD-R746BTU9D 011A 421 30 80 N0001 MA 01 3/3/2014 3/3/2014 12/31/2999) Array ([0] => 2 KW-XG56T2UD 057A 25081 79 440 N0001 MA 01 3/3/2014 3/3/2014 12/31/2999) Array ([0] => 3 KD-R646U9D 012B 561 1 60 N0001 MA 01 3/3/2014 3/3/2014 12/31/2999)

編輯

變化while ($data = fgetcsv($handle,1000,",","'")){成爲while ($data = fgetcsv($handle,1000,"\t","'")){。後來的print_r（$數據）：

array(1) { ["csv"]=> array(5) { ["name"]=> string(17) "prod_schedule.csv" ["type"]=> string(8) "text/csv" ["tmp_name"]=> string(14) "/tmp/phpb1ji8u" ["error"]=> int(0) ["size"]=> int(1943264) } } 

Array ([0] => RecNo [1] => Model_Name [2] => Lot_Number [3] => Start_Serial [4] => Qty [5] => Lot_Qty [6] => Line [7] => Line_Name [8] => Start_Date [9] => End_Date [10] => Due_Date) 
Array ([0] => 1 [1] => KD-R746BTU9D [2] => 011A [3] => 421 [4] => 30 [5] => 80 [6] => N0001 [7] => MA 01 [8] => 3/3/2014 [9] => 3/3/2014 [10] => 12/31/2999) 
Array ([0] => 2 [1] => KW-XG56T2UD [2] => 057A [3] => 25081 [4] => 79 [5] => 440 [6] => N0001 [7] => MA 01 [8] => 3/3/2014 [9] => 3/3/2014 [10] => 12/31/2999) 
Array ([0] => 3 [1] => KD-R646U9D [2] => 012B [3] => 561 [4] => 1 [5] => 60 [6] => N0001 [7] => MA 01 [8] => 3/3/2014 [9] => 3/3/2014 [10] => 12/31/2999) 

文件還沒有上傳，顯示：PHP Notice: Undefined index: csv。然後把var_dump喜歡：

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

我array(0) { }。

Answer 1

只需一眼通過，我覺得

if (!empty($_GET[success])) 

應該

if (!empty($_GET['success'])) 

Answer 2

我認爲這個問題是你如何放置你做一段時間。使用DO while語句時，它會首先運行裏面做的代碼，然後檢查while語句。

你應該做的，而不是

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,",","'")); 

使用

while($data = fgetcsv($handle,1000,",","'")){ 
     if ($data[0]) { 
     mysql_query("INSERT INTO contacts (contact_first, contact_last, contact_email) VALUES 
      (
       '".addslashes($data[0])."', 
       '".addslashes($data[1])."', 
       '".addslashes($data[2])."' 
      ) 
     "); 
    } 



} 

它基本上是相同的，只是在while()首先做任何代碼的內部之前執行的代碼。

希望這會有所幫助。

Answer 3

通過print_r的輸出去（$數據），您提供的，我可以看到田野看起來是製表符分隔。

您的代碼在這裏：

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

正在使用fgetcsv功能領域之間的標準逗號分隔符 - 這是常見的做法，爲CSV代表逗號分隔值。

爲了讓您的腳本中使用標籤作爲分隔符來讀取值，試着調整上述線路：

while ($data = fgetcsv($handle,1000,"\t","'")){ 

希望這有助於:)
