上傳時看不到.csv文件

Question

我試圖上傳一個字段到mysql數據庫。該字段可以通過用戶手動輸入或上傳包含該字段的.csv文件來上傳。手動打字效果很好，但是當我嘗試使用.csv上傳時，它看不到該文件並跳到我的代碼的「其他」部分。這是我的代碼：

<?php 
    $classname = $_POST['classname']; 
    $classname = stripslashes($classname); 
    $classname = mysql_real_escape_string($classname); 


    $save = $_POST['save']; 
    $save = stripslashes($save); 
    $save = mysql_real_escape_string($save); 


    $myfile = $_POST['myfile']; 
    $myfile = stripslashes($myfile); 
    $myfile = mysql_real_escape_string($myfile); 


    $import = $_POST['import']; 
    $import = stripslashes($import); 
    $import = mysql_real_escape_string($import); 

    if($classname && $save) 
    { 
     $choose_db; 
     $sql="INSERT INTO classes (`class`) VALUES ('$classname')"; 
     $res=mysql_query($sql, $connect) or die (mysql_error()); 

     if ($res) 
     { 
      echo "<script type='text/javascript'> 
        alert('Class added succefully'); 
        window.location='../classes.php' 
       </script>"; 
     } 
     else 
     { 
      echo "<script type=text/javascript'> 
        alert('Class not added'); 
        window.location('../classes.php'); 
       </script"; 
     } 
    } 




    elseif ($import && $myfile) 
    { 
     echo $filename = $_FILES["file"]["tmp_name"]; 

     if ($_FILES["file"]["size"] > 0) 
     { 
      $thefile=fopen($filename, "r"); 

      while (($thedata = fgetcsv($thefile, 10000, ",")) !== FALSE) 
      { 
       $sql_file="INSERT INTO classes (`class`) VALUES ('$thedata[1]')"; 
       $res_file=mysql_query($sql_file, $connect) or die (mysql_error()); 

       if (!$res_file) 
       { 
        echo "<script type='text/javascript'> 
           alert ('Invalid file type!'); 
           window.location = '../classes.php'; 
         </script>     
        "; 
       } 
      } 

      fclose($thefile); 

      echo "<script type='text/javascript'> 
         alert ('File Imported Successfully!'); 
         window.location = '../classes.php'; 
        </script>     
      "; 

     } 
    } 




    else 
    { 
     echo "<script type='text/javascript'> 
         alert('Fill the form or choose a CSV file'); 
         window.location='../classes.php' 
       </script>"; 
    } 


?> 

這裏是HTML表單

<form class="form-horizontal" method="post" name="addclass" action="popups/saveclass.php"> 

    <div style="margin:5px" class="form-group"> 
     <label class="col-sm-12">New Class Name:</label> 
     <div class="col-sm-12"> 
      <input type="text" name="classname" class="form-control" placeholder="Class Name" /> 
     </div> 
    </div> 

    <center><input type="submit" name="save" value="Save" id="submit" style="width:200px; height:30px; font-family:'Trebuchet MS', Arial, Helvetica, sans-serif; color:#002435; font-size:14px; cursor:pointer"/> 
    </center> 
</form> 

<form class="form-horizontal" method="post" name="uploadcsv" action="popups/saveclass.php" enctype="multipart/form-data"> 
    <br /><center>Or Upload CSV file</center><br /> 


    <div style="margin:5px" class="form-group"> 

     <div class="col-sm-12"> 
      <input type="file" name="myfile" class="form-control" /> 
     </div> 
    </div> 

    <center><input type="submit" name="import" value="Import" style="width:200px; height:30px; font-family:'Trebuchet MS', Arial, Helvetica, sans-serif; color:#002435; font-size:14px; cursor:pointer"/></center> 

</form> 

Answer 1

文件上傳僅在$_FILES，不$_POST。所以$myfile = $ _POST ['myfile']; won't do anything, get rid of everything related to $ myfile`。

由於您沒有將其存儲在數據庫中，因此無需撥打stripslashes或mysql_real_escape_string,$_POST['import']。

您使用$_FILES['file']，但輸入的名稱是myfile，所以它應該是$_FILES['myfile']。

因此，代碼應該是：

elseif (isset($_POST['import'], $_FILES['myfile'])) { 
    echo $filename = $_FILES["myfile"]["tmp_name"]; 
    if ($_FILES["myfile"]["size"] > 0) 
    { 
     ... 
    } 
}
