我想开始说我正在学习，我正在努力理解$_FILES 和$file_handler 这让我疯狂地使用这个功能，从前端表单上传附件。
我昨天发现的question 那是在使用$_FILES 在同一个函数中进行重写，所以一些好心的家伙建议用不同的方式更改此变量，如$whatever. 这两个文件都可以管理和上传，但当然这还没有发生，而且only files are uploaded. 有两个相对命名的表单输入：
图像：name="moreimages"name="morefiles"基本上，我的php已经达到了这一点：
if ($_FILES)
{
// Get the upload attachment files
$images = $_FILES[\'moreimages\'];
foreach ($images[\'name\'] as $key => $value)
{
if ($images[\'name\'][$key])
{
$image = array(
\'name\' => $images[\'name\'][$key],
\'type\' => $images[\'type\'][$key],
\'tmp_name\' => $images[\'tmp_name\'][$key],
\'error\' => $images[\'error\'][$key],
\'size\' => $images[\'size\'][$key]
);
//here I\'ve changed the $_FILES variable into something else
$my_processed_images = array("moreimages" => $image);
foreach ($my_processed_images as $image => $array)
{
$newupload = project_images($image,$pid);
}
}
}
// Get the upload attachment files
$files = $_FILES[\'morefiles\'];
foreach ($files[\'name\'] as $key => $value)
{
if ($files[\'name\'][$key])
{
$file = array(
\'name\' => $files[\'name\'][$key],
\'type\' => $files[\'type\'][$key],
\'tmp_name\' => $files[\'tmp_name\'][$key],
\'error\' => $files[\'error\'][$key],
\'size\' => $files[\'size\'][$key],
\'post_mime_type\' => $files[\'type\'][$key]
);
$_FILES = array("morefiles" => $file);
foreach ($_FILES as $file => $array)
{
$uploadfile = project_file($file,$pid);
}
}
}
}
我的函数看起来像
function project_images($file_handler, $pid)
{
if ($_FILES[$file_handler][\'error\'] !== UPLOAD_ERR_OK) __return_false();
require_once(ABSPATH . "wp-admin" . \'/includes/image.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/file.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/media.php\');
$image_id = media_handle_upload( $file_handler, $pid );
return $image_id;
}
function project_file($file_handler, $pid)
{
if ($_FILES[$file_handler][\'error\'] !== UPLOAD_ERR_OK) __return_false();
require_once(ABSPATH . "wp-admin" . \'/includes/image.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/file.php\');
require_once(ABSPATH . "wp-admin" . \'/includes/media.php\');
$file_id = media_handle_upload( $file_handler, $pid );
update_post_meta($file_id,\'is_prj_file\',\'1\');
return $file_id;
}
我知道我的
$file_handler 但我不知道该怎么办。真正发生的是调试
$more_images 为空且未考虑，且
$_FILES 进入第二个循环
is uploaded 相反你能开车送我吗？
EDIT
“我的HTML表单”字段如下所示：
<input id="moreimages" accept="image/png, image/jpeg, image/gif" type="file" name="moreimages[]" >
<input id="morefiles" accept=".zip,.pdf,.rar,.doc,.docx,.xls,.xlsx,.ppt,.pptx,.psd,.ai" type="file" name="morefiles[]" >
此外，我的AJAX POST状态正常，将这些参数发送给
moreimages:
Content-Disposition: form-data; name="moreimages[]"; filename="Screen Shot 2016-04-05 at 16.48.10.png"
Content-Type: image/png
PNG
这些参数用于
morefiles:
Content-Disposition: form-data; name="morefiles[]"; filename="articolo-slow-food-ararat.docx"
Content-Type: application/vnd.openxmlformats-officedocument.wordprocessingml.document
因此，我再次思考问题，这些数据是如何接收到php中的。

我确实覆盖了一些东西。我没有验证，只构建了结构化的验证和上传功能。您可以根据需要验证文件。
