php - PHP Laravel 多文件上传使用两个表
问题描述
我正在构建一个Laravel
-nova 应用程序,并且我有一个<form>
可以上传多个文件的位置。所以我必须表 -single_applications
和single_application_files
. 所以,当我填写表格时,数据会正确发布,但文件除外,我完全不知道为什么,例如我不知道我做错了什么。
这是刀片模板:
<form method="POST" action="{{ route('application.store') }}">
<div class="input-group mb-3">
<input name="name" type="text" class="form-control" placeholder="Name" autocomplete="name" required>
</div>
//...and a bunch more
//...then the file input
<div class="form-group col">
<div class="custom-file file">
<input type="file" class="custom-file-input" id="attachment-1" name="attachment_cv[]" accept=".pdf,.doc,.docx,application/msword,.png,.jpg,.jpeg,.gif">
<label class="custom-file-label" for="attachment-1">Add File</label>
<div class="addBtnContainer">
<a href="#" data-js="add" class="js-addFileField">+ Add</a>
</div>
</div>
</div>
</form>
由于可用性,我不想要<input type="file" multiple />
,而是用户可以单击add
并在 的帮助下jquery
,出现另一个文件输入字段。
我的SingleApplication
-Model 看起来像这样:
class SingleApplication extends Model
{
protected $fillable = [
'avatar', 'name', 'email', 'phone', 'address', 'zipcode', 'city',
'education', 'about', 'birthyear', 'job_category', 'status','vehicles', 'worktime', 'clothing'
];
}
我的SingleApplicationFile
-Model 看起来像这样
class SingleApplicationFile extends Model
{
protected $fillable = [
'attachment_cv', 'files_id', 'attachment_cv_name', 'attachment_cv_size', 'single_applications_id'
];
}
到目前为止一切顺利,所以我确实使用axios
过发布数据,所以它看起来是这样的:
$('#singleApplication button[type="submit"]').click(function(e) {
e.preventDefault();
var formData = new FormData();
formData.append(
"name",
$("#singleApplication")
.find('input[name="name"]')
.val()
);
// ...etc. etc. the same with all other fields
// HERE I FETCH THE ATTACHMENT FILES
var attFiles = [];
$('input[name="attachment_cv[]').each(function() {
attFiles.push($(this).prop("files")[0]);
});
formData.append("attachment_cv", attFiles);
axios.post($("#singleApplication form").attr("action"), formData)
.then(response => {
})
.catch(error => {
console.log(error.response.data); // DEBUG
});
});
});
现在涉及到控制器,这就是我认为出了问题的地方。
use App\SingleApplication;
use App\SingleApplicationFile;
class SingleApplicationsController extends Controller
{
public function store()
{
$application = SingleApplication::create([
'email' => request()->email,
'name' => request()->name,
'avatar' => request()->avatar,
'phone' => request()->phone,
'address' => request()->address,
'zipcode' => request()->zipcode,
'city' => request()->city,
'birthyear' => request()->birthyear,
'job_category' => request()->job_category,
'education' => request()->education,
'about' => request()->about,
'vehicles' => request()->vehicles,
'worktime' => request()->worktime,
'clothing' => request()->clothing,
'status' => request()->status,
]);
if (request()->hasFile('attachment_cv')) {
$files = request()->file('attachment_cv');
foreach ($files as $file) {
$filename = $file->getClientOriginalName();
$extension = $file->getClientOriginalExtension();
$filesize = $file->getSize();
$path = Storage::disk('local')->put('attachments/application_files', request()->file($filename));
$application_files = SingleApplicationFile::create([
'files_id' => $application->id,
'single_application_id' => $application->id,
'attachment_cv' => $path,
'attachment_cv_name' => $extension,
'attachment_cv_size' => $filesize,
]);
new SingleApplicationFile($application_files);
return response()->json('OK', 200);
}
}
}
那么,有人可以告诉我,我做错了什么吗?如前所述,除了文件之外的所有数据都经过,数据库中的表保持为空。
更新
由于某种原因,请求未通过该行
if (request()->hasFile('attachment_cv')) {}
这个怎么可能?
解决方案
由于您需要上传文件,请enctype="multipart/form-data"
以表格形式添加,我request()->file($filename)
在这一行中注意到了
$path = Storage::disk('local')->put('attachments/application_files', request()->file($filename));
您的字段名称是 attachment_cv 而不是 $filename。因此,您需要尝试以下方法之一
$name = md5('myfile_'.date('m-d-Y_hia')).'.'.$extension; //This will save a unique file name
$path = Storage::disk('local')->put('attachments/application_files/'.$name, $_FILES['attachment_cv']['name'][$i]);
// 根据 foreach 递增 $i
$path = Storage::disk('local')->put('attachments/application_files/'.$name, $filename);
您也可以使用$path = $filename->store('attachments/application_files');
这将自动生成一个随机文件名
