php用預定義文件名上傳多個文件

我想用預定義文件名上傳多個文件，這有可能嗎？如何從php中檢索名稱？php用預定義文件名上傳多個文件

如何從php中檢索名稱'doc1'和'doc2'？

我的代碼：

<? 
 
$valid_formats = array("jpg", "png", "gif", "zip", "bmp"); 
 
$max_file_size = 1024*1024; //1MB 
 
$path = "uploads/doc/"; // Upload directory 
 
$count = 0; 
 

 
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){ 
 
    // Loop $_FILES to exeicute all files 
 
    foreach ($_FILES['files']['name'] as $f => $name) { 
 
     if ($_FILES['files']['error'][$f] == 4) { 
 
      continue; // Skip file if any error found 
 
     } 
 
     if ($_FILES['files']['error'][$f] == 0) { 
 
      if ($_FILES['files']['size'][$f] > $max_file_size) { 
 
       $message[] = "$name is too large!."; 
 
       continue; // Skip large files 
 
      } 
 
      elseif(! in_array(pathinfo($name, PATHINFO_EXTENSION), $valid_formats)){ 
 
       $message[] = "$name is not a valid format"; 
 
        continue; // Skip invalid file formats 
 
      } 
 
      else{ // No error found! Move uploaded files 
 
       if(move_uploaded_file($_FILES["files"]["tmp_name"][$f], $path.$name)) 
 
        $count++; // Number of successfully uploaded file 
 
       } 
 
      } 
 
     } 
 
} 
 
?> 
 
<html lang="en"> 
 
<head> 
 
    <meta charset="UTF-8" /> 
 
    <title>Multiple File Ppload with PHP</title> 
 
</head> 
 
<body> 
 
    <form action="" method="post" enctype="multipart/form-data"> 
 
    Doc1: <input type="file" id="file" name="files['doc1']" multiple="multiple" accept="image/*" /><br> 
 
    Doc2: <input type="file" id="file" name="files['doc2']" multiple="multiple" accept="image/*" /><br> 
 
    <input type="submit" value="Upload!" /> 
 
</form> 
 
</body> 
 
</html>

在move_uploaded_file函數中上傳後更改文件名 –

您可以在PHP腳本中命名它。您不需要使HTML代碼變得複雜。多個陣列並能夠上傳多個文件？（這甚至不工作，因爲名稱不是多個文件數組）。使用Doc1：''然後運行PHP腳本兩次。 – AkiEru

做檢查PHP代碼下方，將返回你上傳的文件的所有細節。

if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST") 
{ 
    echo "File Names:<br>Doc1= ".$_FILES['files']['name']["'doc1'"]; 
    echo "<br>Doc2= ".$_FILES['files']['name']["'doc2'"]; 
    echo "<br><br>"; 

    echo "File Types:<br>Doc1= ".$_FILES['files']['type']["'doc1'"]; 
    echo "<br>Doc2= ".$_FILES['files']['type']["'doc2'"]; 
    echo "<br><br>"; 

    echo "Tmp Name:<br>Doc1= ".$_FILES['files']['tmp_name']["'doc1'"]; 
    echo "<br>Doc2= ".$_FILES['files']['tmp_name']["'doc2'"]; 
    echo "<br><br>"; 

    echo "Error:<br>Doc1= ".$_FILES['files']['error']["'doc1'"]; 
    echo "<br>Doc2= ".$_FILES['files']['error']["'doc2'"]; 
    echo "<br><br>"; 

    echo "Size:<br>Doc1= ".$_FILES['files']['size']["'doc1'"]; 
    echo "<br>Doc2= ".$_FILES['files']['size']["'doc2'"]; 
    echo "<br><br>"; 
} 
?>
