我在WordPress中运行了这个自定义上传脚本,因为我不想/不需要使用内置的WordPress脚本。
The file test.csv could not be copied, try again 无法理解为什么会出现此错误!

<?php
$updir = 'wp-content/themes/ddpp/upload_csv/';
$max_size = 100;  
$allowtype = array('csv'); 
if (isset($_FILES['field_name'])) {

if ($_FILES['field_name']['error'] > 0) {
echo 'Error: '. $_FILES['field_name']['error']. '<br />';
}
else {
// get the name, size (in kb) and type (the extension) of the file
$fname = $_FILES['field_name']['name'];
$fsize = $_FILES['field_name']['size'] / 1024;
$ftype = end(explode('.', strtolower($fname)));

// checks if the file already exists
if (file_exists($updir. $fname)) {
  echo 'The file: '. $fname. ' already exists';
}
else {
  // if the file not exists, check its type (by extension) and size
  if (in_array($ftype, $allowtype)) {
    // check the size
    if ($fsize <= $max_size) {
      // uses  function to copy the file from temporary folder to $updir
      if (!move_uploaded_file ($_FILES['field_name']['tmp_name'], $updir. $fname)) {
        echo 'The file '. $fname. ' could not be copied, try again';
      }
      else {
        echo $fname. ' ('. $fsize. ' kb) was successfully uploaded';
      }
    }
    else {
      echo 'The file '. $fname. ' exceeds the maximum permitted size, '. $max_size. ' KB';
    }
  }
  else {
    echo $fname. ' - invalid file type';
  }
}
  }
}
?>
<div style="display: inline-block; width: 25%; vertical-align: top;">
<form action="" method="post" enctype="multipart/form-data">
    <input type="file" name="field_name" /><br />
    <input type="submit" name="submit" value="Submit" />
</form>

让我们了解为什么会发生这种情况。你得到了错误 The file test.csv could not be copied, try again ,因此问题在于:

if (!move_uploaded_file ($_FILES['field_name']['tmp_name'], $updir. $fname))

move_uploaded_file() ,以下是错误的原因:

如果文件名不是有效的上载文件,则不会执行任何操作,move\u upload\u file()将返回FALSE。

如果文件名是有效的上载文件,但由于某种原因无法移动,则不会发生任何操作,move\u uploaded\u file()将返回FALSE。 此外,将发出警告。

ini_set('display_errors', 1);
error_reporting(E_ALL);

最常见的问题是文件目录不可写,因为PHP无法在目标目录中创建文件名。确保目录存在,并且PHP进程可以写入该文件夹。

代码在此失败

  if (!move_uploaded_file ($_FILES['field_name']['tmp_name'], $updir. $fname)) {
    echo 'The file '. $fname. ' could not be copied, try again';
  }

这意味着move_uploaded_文件无法执行您需要它执行的操作。检查php错误日志,可能会出现权限错误。您可能使用FTP或其他方法创建了目录,因此apache无法写入该目录。

chown -R apache /wherever/the/dir/is
