How do you put a message after a successful action on laravel?

Avante last edited by
How long has it been since you started studying laravel and the question arose how after the challenge of the method in the counteraller to return any message?
```
$this->session->set_flashdata('msg', '<div class="alert alert-success text-left">' . $this->lang->line('success_message') . '</div>');
   $this->load->view('test', $data);
```

To report on the success of the operation:
In contrast
```
return redirect()->route('ваш_роут')->with('success', 'урааа');
```
Blade.
```
@if (session('success'))
    {{ session('success') }}
@endif
```
To report the error:
In contrast
```
return redirect()->route('ваш_роут')->withError('нееееет');
```
It's situational. For example, in lieu of recirculation and rolling, the back(s) may be added, or at all, the user ' s port through withInputs().
Blade.
```
@if($errors->any())
    @foreach($errors->all() as $error)
        {{ $error }}
    @endforeach
@endif
```

Errors in your scriptNo mysqli_query($sql) and yes mysqli_query($strcon,$sql) No mysql_close($strcon); and yes mysqli_close($strcon);The $_POST variables as you well should know receives the data passed by an HTTP POST request. Probably these variables were not passed in the request yet and therefore there are no. It's no use calling something that doesn't exist.SolutionValidate the client side and server side. That way will avoid error Notice: Undefined index and avoid an INSERT without values.The customer side: The attribute. requiredThis is a Boolean attribute used to indicate that a determining form field is mandatory for sending it. By adding this attribute to a form field, the browser forces the user to enter data in that field before submitting the form.This validation replaces basic form validation implemented with JavaScript, making things a little more useful and saving us some development timeExamples: <input class="form-control required" name="id" type="text" required><select class="form-control" name="tipo" required>On the server side// Cria uma variável que terá os dados do erro $erro = false; // Verifica se o POST tem algum valor if ( !isset( $_POST ) || empty( $_POST ) ) { $erro = 'Nada foi postado.'; } // Cria as variáveis dinamicamente foreach ( $_POST as $chave => $valor ) { // Remove todas as tags HTML // Remove os espaços em branco do valor $valor=trim($valor); $$chave = trim( strip_tags( $valor ) ); // Verifica se tem algum valor nulo if ( empty ( $valor ) || $valor=="" ) { $erro = 'Existem campos em branco.'; } } // Se existir algum erro, mostra o erro if ( $erro ) { echo $erro; } else { // Se a variável erro continuar com valor falso // Faça o INSERT aqui include_once("conecta.php"); $idPrest = $_POST['id']; $razaoSoc = $_POST['razao_social']; $NomeFanta = $_POST['nome_fantasia']; $NumCnpj = $_POST['CNPJ']; $Tip = ['tipo']; $sql = "INSERT INTO cadastroprestador(ID_PREST,Razão_Social,Nome_Fantasia,CNPJ) VALUES ('$idPrest', '$razaoSoc', '$NomeFanta', '$NumCnpj')"; mysqli_query($strcon,$sql) or die ("erro ao tentar cadastrar"); echo "Cadastrado Com sucesso"; mysqli_close($strcon); } Why client side validation (Front-end) and server side (Back-end)?Validating data being sent by the user only in javascript is not enough because of:if the user disables javascript, you can end up with invalid data on the serverBecause the front end is accessible in the browser. And all the code that is there can end up being changed by someone who has advanced knowledge and bad intentions. JavaScript code can perfectly be changed and so validation can be dug.server validations make a site less susceptible to malicious robotsIn short... it is worthwhile to preach against all these unknown agents, making validation on the server (which is the most reliable agent) as being the main... and javascript, as a validation agilizer, because you do not need to go on the server.

Analyzing the code and what /questions/tagged/laravel in https://laravel.com/docs/5.8/validation what you've done is like that, that's how it works, of course it has a way around can add features to this class so that when a message is passed in your constructor may have the option to use a new validation message, example:<?php namespace App\Rules; use Illuminate\Contracts\Validation\Rule; class ValidarValor implements Rule { private $message; public function __construct($message = null) { $this->message = $message; } public function passes($attribute, $value) { $expressao = "/^([1-9]{1}[\d]{0,2}(.[\d]{3})*(,[\d]{0,2})?|[1-9]{1}[\d]{0,}(,[\d]{0,2})?|0(,[\d]{0,2})?|(,[\d]{1,2})?)$/"; return (preg_match($expressao,$value)); } public function message() { return $this->message ?? 'O campo :attribute está no formato incorreto.'; } } with this change made in your contructor now has the possibility to change the default message of your rule as follows:<?php namespace App\Http\Requests; use App\Rules\ValidarValor; use Illuminate\Foundation\Http\FormRequest; class PagtoRequest extends FormRequest { public function authorize() { return true; } public function rules() { return [ 'valor_parcela' => [ 'required', new ValidarValor('Existem parcelas com valores inválidos') // passe aqui !!! ] ]; } public function messages() { // remova somente aquele validação que foi customizada na classe return [ ]; } } References https://laravel.com/docs/5.8/validation https://stackoverflow.com/questions/56384220/how-to-override-the-message-of-the-custom-validation-rule-in-laravel

Probably a variable. from_user contains data on the user who sent the message messagea method get_me returns the data on the belt itself. On your question, "why don't you go without them," I can advise you first to go through the Python work framework (and in this case the text formatting) and then start programming more complicated things.Please always provide a full version of the code so that you can understand what's coming from.

You can use the hexadecimal code. The &xxxx codes are HTML entities and not CSS, you should use an alternative code.ul.breadcumb > li:after{ content: '\00BB'; /** Isso aqui funciona **/ }<ul class="breadcumb"> <li>teste</li> <li>teste</li> <li>teste</li> <li>teste</li> <li>teste</li> </ul>

We should start by writing all the import on the new line. from collections import defaultdicta Second user_by_counter = defaultdict(int)And that's what's supposed to happen in sending a message, more precisely how she's supposed to look. for event in longpoll.listen(): if event.type == VkBotEventType.MESSAGE_NEW: if 'Текст от пользователя' in str(event): if event.from_chat: user_id = event.obj.from_id user_by_counter[user_id] += 1 vk.messages.send( key = (''), #ВСТАВИТЬ ПАРАМЕТРЫ server = (''), ts=(''), random_id = get_random_id(), message='ответ пользователю' , chat_id = event.chat_id )

Method get() and paginate() incompatible. get() It's a collection already. paginate() It also gives a collection, but it's limited to pages. When you try to use paginate() ♪ get(), at this point, there are no model methods, and only collections are mistaken for lack of method.So if you want to get the pages, just write. paginate():public function __invoke() { $users = Server::take(2); $topUsers = Server::withCount('topServersUser') ->orderBy('top_user_count','DESC')->paginate(3); return view('main.index', compact('users', 'topUsers' )); }

One thing you need to be clear is if you use update() You mustn't use it anymore. save().If you use update():From what I see, what you want to attach is an array, so I'll assume that column. URLImg contains an array too.$tramite = Tramite::findOrFail($RComunicInter_ID); $tramite->update([ 'URLImg' => json_encode(array_merge(json_decode($tramite->URLImg, true), $data)) ]); The main logic lies here:json_encode(array_merge(json_decode($tramite->URLImg, true), $data)) First you have to get what you have in database, but as a stringYou must turn it into a array using https://www.php.net/manual/en/function.json-decode.php .json_decode($tramite->URLImg, true) Then, using https://www.php.net/manual/en/function.array-merge.php an array that you have in database with the new one, but since you can't save arrays in a column, that new array must convert it to string using https://www.php.net/manual/en/function.json-encode.php .If you use save()It's the same logic:$tramite = Tramite::findOrFail($RComunicInter_ID); $tramite->URLImg = json_encode(array_merge(json_decode($tramite->URLImg, true), $data)); $tramite->save(); If the only thing you want is to match two strings, you simply use the point concatenator (.).

This is JSON (transferring the recording into BDE laravel converts into JSON). var_dump(json_encode(array())); var_dump(json_encode(array(""))); That's the one that's got to write down.

Clean the $k and $v after the cycle, after the end of the cycle, they continue to keep references to the last element of the mass, and the next cycle will not start from where you think.This error is well described in the article http://www.toptal.com/php/10-most-common-mistakes-php-programmers-make

Laravel has an ORM called Eloquent you can use.For example.Suppose you have 4 tables called A, Bs, Cs and Ds We put the s in front of each letter to know that the name of the table is in plural, that is, it contains many letters AEach related to the other in one relationship from one to many. I mean, A has many Bs and Each B belongs to an A. And so until we get to D.You can use Eloquent to create Models/Clases that represent tables. And with the help of with apply eager loading.and place in your code something like$a = App\A::with(['bs', 'bs.cs', 'bs.cs.ds'])->get(); This will execute all the SQLs necessary to take the information of all the relationships of all the elements the As table. I think I used the word every time.Although you can also ignore the with, but this will make Eloquent apply the Lazy Loading that may lead you to the famous problem of the N + 1 queriesat the time of wanting to perform a foreach of your relationshipsforeach($a->bs as $b) { foreach($b->cs as $c) { foreach($c->ds as $d) { } } } In the https://laravel.com/docs/5.6/eloquent-relationships You can see more about this

Which prevents you from getting all the post-request data.$post_recv = $this->input->post(); // returns all POST items with XSS filter I don't think it's going to be hard to see what's going on here?And then I suspect that the following design can be used for the cycle:foreach($post_reqv as $key => $value)...

Json files can be converted through http://php.net/manual/ru/class.directoryiterator.php :$files = new RegexIterator(new DirectoryIterator($path), '/\.json$/i'); foreach ($files as $file) { $news = News::fromJson($file->getFileName()); echo $news->renderHtml(); } The class itself can be done by farewell: class News { protected $title, $description, $author, $date; public function __construct($title, $description, $author, $date) { $this->title = $title; $this->description = $description; $this->author = $author; $this->date = $date; } public static function fromJson($filename) { $data = json_decode(file_get_contents($filename)); $news = $data['news']; $obj = new self($news['title'], $news['description'], $news['author'], $news['date']); } public function renderHtml() { // Рендер c HEREDOC $title = htmlspecialchars($this->title); $author = htmlspecialchars($this->author); $description = htmlspecialchars($this->description); $date = htmlspecialchars($this->date); return <<<HTML <div class="news"> <div class="title"> $title </div> <div class="description"> $description </div> <div class="date inline-block"> <span>$date</span> </div> <div class="author inline-block"> <span>Добавил: </span> $author </div> </div> HTML; } } The method then renders it better to convert to some type of Twig. ♪If the object method does not need the object itself, it must be static. getX/setX methods are better not to be set. You can declare the properties of the public, and when necessary, change their logic in..._get/_set. All data displayed in html shall be screened(htmlspecialchars)All necessary data for the establishment of the facility should be transmitted to the designer in order to prevent the existence of the facility in a non-consistent state.
