Question

我的网站上运行了一些代码，可以很好地从文件输入表单元素上传单个文件 - 但我现在需要一个多文件输入表单元素来接受多个文件并将它们全部上传到服务器并存储以逗号分隔的字符串上传的文件名的详细信息...有关如何使用我在下面使用的代码进行此操作的任何想法：

表单字段：

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

PHP代码（可以接受上传的1个文件但不超过1个？）：

<?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;

我的网站上有类似的代码，这段代码超级旧，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!";

}
}
}
