我有一些代碼在我的網站上運行,很適合從文件輸入表單元素上傳單個文件 - 但我現在需要一個多文件輸入表單元素來接受超過1個文件並全部上傳服務器和存儲在一個逗號分隔字符串上傳的文件名的詳細信息...如何使與代碼這項工作任何想法我使用下面:PHP上傳多個文件的代碼幫助
表單字段:
<input name="logoexamples[]" id="blogoexamples" type="file" class="textInput" value="notrelevant" multiple>
PHP代碼(工作接受1個文件上傳,但不超過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;
