Question

我有一个包含2个文件输入字段的表单。我有一个很好地处理文件上传的PHP脚本 - 但我缺少的是能够在上传完成后从表单中取回文件名值。代码如下。

我想也许更容易调整这些代码以使其特定于上传每个指定文件输入的文件 - 然后我可以轻松地从文件名中取回？

e.g。所以有2个代码块来上传和存储输入的文件名值 - 例如input1和input2 ......？

有什么想法吗？

// 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;

    // 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;
