How to dig to the properties of the object

guilherme

There's an object.

array(1) { 
[0]=> object(yii\web\UploadedFile)#84 (5) { 
    ["name"]=> string(34) "lenovo-laptop-ideapad-z50-back.png" 
    ["tempName"]=> string(44) "E:\serv\OpenServer\userdata\temp\phpD4D6.tmp"
    ["type"]=> string(9) "image/png" 
    ["size"]=> int(51033) 
    ["error"]=> int(0) }
}

I've got to catch up. name♪

In order to gain access to the object ' s properties in the facility ' s array, it is necessary to:
1. Have access to the facility by using its index in the massiva
2. To gain access to the circumference by using the operator ->
```
$yourArray[0]->name
```

$catch=$j; $catch=$catch+$step; What's $? Are you sure it's not like 0 in this case?$step =$_POST['step']; //Чему $step равно здесь? $mod_step = $step / 26; $mod_step = (int) $mod_step; // Если $step было "ерунда", то $mod_step = 0 if($mod_step > 1) { //следовательно это не выполнится $step=$step-$mod_step*26; } $catch=$catch+$step; //и это будет равнозначно $catch = $catch + 0 That's how it works.I mean, make a conclusion on each of these sites and look where the malfunction is. I think it's $.POST.

You transformed the string into object.You need to turn into string again before sending:request(url, function (error, response, body) { let result = JSON.parse(body); result['teste'] = 'teste'; res.status(200).send(JSON.stringify(result)); // ^^^^^^^^^^^^^^ }); Manual: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON

As you did not mention where the variables come from, I will give a general example of a system of templates:DB information:<html> Nome: $nome$ </html> PHP<?php $contrato = /* aqui você pega do DB os dados */; $nome = 'José Maria'. $idade = '17'; $contrato = str_replace( '$nome$', $nome, $contrato ); $contrato = str_replace( '$idade$', $idade , $contrato ); ... faça o mesmo para todos os campos ... echo $contrato; ?> Note that in the DB it compensates to use a markup that does not confuse, as $nome$ instead of $nome, not to have ambiguity if there is something like $nomenclatura (which begins with $nome also). If you already have a lot in the DB, be careful, with words started in the same way, to change the longest ones first replaces (change the $nomenclatura before $nome $nome will stir something you should not).See the syntax of str_replace using array to make several replacements at once only: $contrato = str_replace( array( '$nome$', '$idade$', '$endereco$' ), // Palavras a trocar array( $nome , $idade , $endereco ), // O que vai por no lugar de cada uma $contrato ) The following question can also help: https://pt.stackoverflow.com/questions/97672/

Yours dd() may be returning an Object yes, but at the time it is running certainly this object comes null, that is, the query does not return anything. There's a little bit of information left to help you better, but at first, Query Builder is not finding any records, his select returns nothing.

I usually use Cookies, LocalStorage or SessionStorage to do that kind of thing. O LocalStorage and SessionStorage are HTML5 features and are very simple to work with. If you want the session to die after closing the browser just use the SessionStorage, otherwise use the LocalStorage which even closing the browser the user will remain logged in.The big problem of these two storages is that old browsers do not fully support you, so you need to evaluate if your user will not use an IE7 of life...Cookies can be useful if you want a medium term between SessionStorage and LocalStorage, as you can define a "vality" for Cookie.One advantage of Cookie is that it is a feature supported by older browsers, it is only a bit boring to read and record values. I usually use a Cookie. js that I found on the internet, let me know if you need me to include in the answer.Anyway, you can search a little more about every feature that I've passed you and set what the best strategy will be.Then you could basically do the authentication system as follows:When authenticating, the server generates a token or some kind of unique identification for you and returns it;You take this return and record it in a cookie, localstorage or sessionstorage;Whenever the user is browsing, you must recover this value, send to the server and if it is valid to complete the navigation, otherwise send to the login or error screen.When making the logoff just delete the sessionstorage, localstorage or cookie values and invalidate the token or unique identifier on the server.I hope I helped.EDITPHP offers the global $_SESSION that can also help you. Then it is at your discretion.

If you want to validate it to be 4 digits positive You must consider that a negative number contains the sign - So a chain with a negative number would be something like: -1234, its length is already greater than 4, then from that here you can already rule out a valid string.So the code is simple, though taking into account the observation I made you, the caste of $numero to the whole, you could do it with a regex (to validate that they are only numbers), but to maintain the simple code I will leave the caste and the validation.// $combi = $_GET['combinacion']; //Contiene: 1234 $combi = "1234"; function validar($str) { $valido = "Son 4 digitos positivos"; $novalido = "No son 4 digitos o no son positivos"; if (strlen($str) == 4) { foreach(str_split($str) as $numero) { if ((int)$numero < 0) return json_encode(array("resp" => $novalido)); } return json_encode(array("resp" => $valido)); } return json_encode(array("resp" => $novalido)); } echo validar($combi); {"resp":"Son 4 digitos positivos"} echo validar("123"); {"resp":"No son 4 digitos o no son positivos"} echo validar("1023"); {"resp":"Son 4 digitos positivos"} echo validar("1abc"); {"resp":"No son 4 digitos o no son positivos"}

I think the problem might be VALUES and I would write the statement as the following: INSERT INTO `users` (`nUserId`, `vLoginName`, `vFirstName`, `vLastName`, `vEmail`) SELECT '$entity_id', '$name', '$firstname', '$lastname', '$email' FROM dual WHERE NOT EXISTS (SELECT * FROM `users` WHERE `nUserId`='$entity_id' AND `vEmail` = '$email')

You can use a framework of php as laravel that already brings vuejs https://laravel.com/docs/5.6/frontend#writing-vue-components Another option if you don't want to use Laravel is importar the script vuejsin your .php file for example:<?php <div id="app"> {{ message }} </div> <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script> <script> var app = new Vue({ el: '#app', data: { message: 'Hello Vue!' } }) </script>

So you can use T, your class must be type Tpublic class MiClase<T> { public string title { get; set; } public string description { get; set; } public List<T> objectList { get; set; } } After flames and instances of the type you want and your List will be string type for example, you lack the method where you fill your list.public partial class help : secondaryForm.secondaryForm { MiClase<string> miClase = new MiClase<string>(); public help() { InitializeComponent(); gridControlHelp.DataSource = miClase.objectList; } private void help_Load(object sender, EventArgs e) { try { setFormTitle(title); setFormDescription(description); } catch (Exception ex) { MessageBox.Show($"help_Load: {ex.Message}"); } } }

In order to change the object of the QML file described on the side, it is necessary to declare the property and assign it the necessary properties.For example:Item fileRect.qmlimport QtQuick 2.9 import QtQuick.Controls 2.2 Item { height: 100 width: 100 property string myString Rectangle { anchors.fill: parent color: "black" } Text { id: myText anchors.centerIn: parent text: myString font.pixelSize: 18 color: "white" } } declare property string myString and assign value to the text: object id: myTextmain.qmlimport QtQuick 2.9 import QtQuick.Controls 2.2 import QtQuick.Layouts 1.3 ApplicationWindow { id: main height: 300 width: 300 visible: true ColumnLayout { anchors.centerIn: parent spacing: 3 ItemRect { id: myItem myString: "DEFAULT" } Button { id: btn text: "Change" onClicked: { myItem.myString = "Pasted Text" } } } } when applied to the button onClicked: change of properties at the id: myItem described in ItemRect.qml

You are trying to get a field that is not included in the form.Input::get("User");If you are a new user, you should create a new instance, for example:$user = new \App\User; $user->name = Input::get('name'); $user->host = Input::get('host'); $user->login = Input::get('login'); $user->password = hash('sha256', Input::get('password')); $user->save($user);

Make use of the method logical https://developer.mozilla.org/ru/docs/Web/JavaScript/Reference/Global_Objects/Array/sort , sorting by size of objectsvar objectArray = [{a : 'a', b : 'b'}, {a : 'a'}, {a : 'a', b : 'b', c : 'c'}]; objectArray.sort(function(a, b) { return Object.keys(a).length - Object.keys(b).length; }); console.log(objectArray);
