表单字段：

<input name="logoexamples[]" id="blogoexamples" type="file" class="textInput" value="notrelevant" multiple>

PHP代码（工作接受1个文件上传，但不超过1 ....？）：

<?php 
// initialize output; 
$output = true; 

// valid extensions 
$ext_array = array('pdf', 'txt', 'doc', 'docx', 'rtf', 'jpg', 'jpeg', 'png', 'eps', 'svg', 'gif', 'ai'); 

// create unique path for this form submission 
//$uploadpath = 'assets/uploads/'; 

// you can create some logic to automatically 
// generate some type of folder structure here. 
// the path that you specify will automatically 
// be created by the script if it doesn't already 
// exist. 

// UPLOAD TO FOLDER IN /ASSETS/UPLOADS/ WITH ID OF THE PARENT PROJECT FOLDER RESOURCE 

// Get page ID 
// $pageid = $modx->resource->get('id'); 
// $uploadpath = 'assets/uploads/'.$pageid.'/'; 

// Get parent page title 
$parentObj = $modx->resource->getOne('Parent'); 
$parentpageid = $parentObj->get('pagetitle'); 
$uploadpath = 'assets/uploads/'.$parentpageid.'/'; 

// get full path to unique folder 
$target_path = $modx->config['base_path'] . $uploadpath; 

// get uploaded file names: 
$submittedfiles = array_keys($_FILES); 

// loop through files 
foreach ($submittedfiles as $sf) { 


// Get Filename and make sure its good. 
$filename = basename($_FILES[$sf]['name']); 

// Get file's extension 
$ext = pathinfo($filename, PATHINFO_EXTENSION); 
$ext = mb_strtolower($ext); // case insensitive 

// is the file name empty (no file uploaded) 
if($filename != '') { 

    // is this the right type of file? 
    if(in_array($ext, $ext_array)) { 

     // clean up file name and make unique 
     $filename = mb_strtolower($filename); // to lowercase 
     $filename = str_replace(' ', '_', $filename); // spaces to underscores 
     $filename = date("Y-m-d_G-i-s_") . $filename; // add date & time 

     // full path to new file 
     $myTarget = $target_path . $filename; 

// JWD - save uploaded filenames as a session var to get it on the redirect hook 
$_SESSION['briefing_submittedfiles_' . $sf] = 'http://www.example.com/assets/uploads/'.$parentpageid.'/'.$filename; 


     // create directory to move file into if it doesn't exist 
     mkdir($target_path, 0755, true); 

     // is the file moved to the proper folder successfully? 
     if(move_uploaded_file($_FILES[$sf]['tmp_name'], $myTarget)) { 
      // set a new placeholder with the new full path (if you need it in subsequent hooks) 
      $modx->setPlaceholder('fi.'.$sf.'_new', $myTarget); 
      // set the permissions on the file 
      if (!chmod($myTarget, 0644)) { /*some debug function*/ } 

     } else { 
      // File not uploaded 
      $errorMsg = 'There was a problem uploading the file.'; 
      $hook->addError($sf, $errorMsg); 
      $output = false; // generate submission error 
     } 

    } else { 
     // File type not allowed 
     $errorMsg = 'Type of file not allowed.'; 
     $hook->addError($sf, $errorMsg); 
     $output = false; // generate submission error 
    } 

// if no file, don't error, but return blank 
} else { 
    $hook->setValue($sf, ''); 
} 

} 

return $output;

我有类似的代码为我的网站，这个代码是超级老，所以不要直接判断或使用它。只是一个例子。

if(isset($_POST['upload'])){ 

for($i=0; $i<count($_FILES['upload']['name']); $i++) { 
//Get the temp file path 
$tmpFilePath = $_FILES['upload']['tmp_name'][$i]; 

//Make sure we have a filepath 
if ($tmpFilePath != ""){ 
//Setup our new file path 
$newFilePath = "../FOLDER NAME/" . $_FILES['upload']['name'][$i]; 

//Upload the file into the temp dir 
if(move_uploaded_file($tmpFilePath, $newFilePath)) { 
    copy($newFilePath, $newFilePath1); 
    $filename = basename($_FILES['upload']['name'][$i]); 
    // add $filename to list or database here 
      $result = "The files were uploaded succesfully."; 
}else{ 
      $result = "There was an error adding the files, please try again!"; 

} 
} 
}
