我有一个正在上传的文件数组。在 validation.php
语言文件,我已经添加了自定义错误信息。
'custom' => [
'images.*' => [
'dimensions' => 'Image ":file" must have a min-height of :min_height pixels and a min-width of :min_width pixels.',
'image' => 'You can only upload images to your gallery. The file ":file" was not an image.',
'mimes' => 'Your image ":file" was an invalid type. Images can only be of the following types: :mimes',
'max' => 'Max file size for each image is :max MB. Your image ":file" is too large.'
]
]
由于有多个文件被上传,我想在显示验证错误时,能够指定错误信息与哪个文件有关。
@if($errors->has('images.*'))
@foreach ($errors->get('images.*') as $message)
<div class="help-block has-error">{{ head($message) }}</div>
@endforeach
@endif
然而。:file
是没有自动填写在信息中的,我不知道怎么弄。
我怎么去做呢?有没有其他的占位符或方法我可以使用?
我也有同样的问题,我试图做的是在一个数组中获取文件名,并将其放在自定义错误信息中,取决于验证类型,在我的例子中,我将获取文件名取决于图像类型(jpeg, png, jpg, SVG, BMP)。
**在控制器申报器中**。
//...
public function store(Request $request)
{
$rules = [ 'imagefile' => 'required',
'imagefile.*' => 'image|mimes:jpeg,png,jpg,svg,bmp', // working on filse size coustom message
];
// To get name of non image file and display in it in error message
if($request->hasfile('imagefile')){
$names = array(); // array for all names of files
foreach($request->Bank_Logo as $file){
// check file extension
if($file->getClientOriginalExtension() != 'jpeg' &&
$file->getClientOriginalExtension() != 'png' &&
$file->getClientOriginalExtension() != 'jpg' &&
$file->getClientOriginalExtension() != 'svg' &&
$file->getClientOriginalExtension() != 'bmp'){
$name= $file->getClientOriginalName (); // get file name
$names[] = $name; // set name of file to array
}
}
// check names array if it empty or not
if(!empty($names)){
/* but all names in custom error,message
* implode funaction to convert array to string
*/
$messages = [
'imagefile.*image' => 'The ' . implode(" and ",$names) . ' not an image file.',
'imagefile.*mimes' => 'The ' . implode(" and ",$names) . ' must be a file of type: jpeg, png, jpg, svg, bmp.'
];
}
}
if(!empty($messages)){
$result = Validator::make($request->all(), $rules, $messages); // with coustom message
//dd($result);
}
else{
$result = Validator::make($request->all(), $rules); // without coustom message
//dd('empty');
}
if($result->fails())
{
return back()->withErrors($result)->withInput($request->all());
}
dd($request->all());
//...
}
在balde文件中
//...
<form>
label class="form-control-label mt-3">{{ __('imagefileLogo') }}</label>
<div class="file-loading">
<input id="imagefile" name="imagefile[]" type="file" multiple>
</div>
@if ($errors->has('imagefile'))
<span class="invalid-feedback" style="display: block;" role="alert">
<strong>{{ $errors->first('imagefile') }}</strong>
</span>
@endif
@if ($errors->has('imagefile.*')) <!--in case if we have multiple file-->
<span class="invalid-feedback" style="display: block;" role="alert">
<strong>{{ $errors->first('imagefile.*') }}</strong>
</span>
@endif
<form>
//...
同样的事情,你可以做的文件大小。
