Question

我无法理解为什么这段代码不起作用。 load_docs_2.php的输出是： Array（）文件类型不正确。这是在XAMPP上运行。

HTML是：

<form id="import_form" method="post" action="load_docs_2.php" enctype="multipart/form-data">
  <label for "importfile">Import PDF File</label><br>
  <input id="import_name" name="load" type="file" value="Upload File"><br><br>
  <input id="import" name="import" type="submit" value="Import">
</form>

load_docs_2.php是：

<?php

// Capture file data

print_r($_FILES);

$loadname = $_FILES["load"]["name"];  // name contains original name
$loadname_temp = $_FILES["load"]["tmp_name"];  // tmp_name contains the temporary file name

// Check file meta data
$import_size = $_FILES["load"]["size"];
$import_type = $_FILES["load"]["type"];

// Setting target folder
$target_dir = "./Staff Docs";
$target_file = $target_dir . $loadname;  // Create target file path

// Move to import folder

$allowed =  array('pdf');
$ext = pathinfo($loadname, PATHINFO_EXTENSION);

if (!in_array($ext,$allowed))
{
    echo 'Incorrect file type';
}    
else
{
    move_uploaded_file($loadname_temp, $target_file);
}

?>

为什么文件加载不起作用？

Answer 1

您可以更改此代码

$target_dir = "Staff Docs/";

现在工作正常

Answer 2

您的目标文件不正确。目标目录和文件之间没有目录分隔符，因此结果本质上是错误的。

 <?php

    // Capture file data

    print_r($_FILES);

    $loadname       = $_FILES["load"]["name"];  // name contains original name
    $loadname_temp  = $_FILES["load"]["tmp_name"];  // tmp_name contains the temporary file name

    // Check file meta data
    $import_size    = $_FILES["load"]["size"];
    $import_type    = $_FILES["load"]["type"];

    // Setting target folder
    //$target_dir   = "./Staff Docs";   //<== THIS IS WHERE THE PROBLEM WAS...
    $target_dir     = "./Staff Docs/";  //<== ADD A DIRECTORY SEPARARATOR BEFORE CONCATENATING WITH $loadname...
    $target_file    = $target_dir . $loadname;  // Create target file path

    // Move to import folder
    $allowed        =  array('pdf');
    $ext = pathinfo($loadname, PATHINFO_EXTENSION);

    if (!in_array($ext,$allowed)){
        echo 'Incorrect file type';
    }else{
        move_uploaded_file($loadname_temp, $target_file);
    }

或者，您可以直接在描述$ target_file的行上添加目录分隔符，如下所示：

 <?php

    // Capture file data

    print_r($_FILES);

    $loadname       = $_FILES["load"]["name"];  // name contains original name
    $loadname_temp  = $_FILES["load"]["tmp_name"];  // tmp_name contains the temporary file name

    // Check file meta data
    $import_size    = $_FILES["load"]["size"];
    $import_type    = $_FILES["load"]["type"];

    // Setting target folder
    $target_dir     = "./Staff Docs";   //<== THIS IS WHERE THE PROBLEM WAS...
    $target_file    = $target_dir . DIRECTORY_SEPARATOR . $loadname;  // Create target file path

    // Move to import folder
    $allowed        =  array('pdf');
    $ext = pathinfo($loadname, PATHINFO_EXTENSION);

    if (!in_array($ext,$allowed)){
        echo 'Incorrect file type';
    }else{
        move_uploaded_file($loadname_temp, $target_file);
    }

为什么我的文件加载不能在PHP中运行？
