Maybe we should use a common interface and a static class instead of callback.

Your question is not entirely clear. ReactJS is a front-end, PHP is a back-and. ReactJS can be tied to a NYBOYBA type of baek-and even if it is Java, Python, Ryby, etc.On the basis of where to keep id, there’s a big choice, from the cue to the localStorage and sessionStorage.There’s the same CacheStorage and IndexedDb. As you understood from the name, they are all used for different purposes.

Shipping via ♪ is correct, but note that you are already displaying the id ($id = $_GET[‘id’];) URL, what makes this visible id to all. This is a matter of taste, but you should really worry about good practices, SQL Injection, etc. Search for on Google: http://rberaldo.com.br/boas-praticas-programacao-php/ https://pt.stackoverflow.com/questions/9734/como-evitar-sql-injection-em-minha-aplica%C3%A7%C3%A3o-php Success!

JSON is not intended for dosing.Translation of lines can be done using a state constant PHP_EOLfile_put_contents(‘data.json’, $new_post.PHP_EOL, FILE_APPEND);
It won’t help. Two records should look like this:[
{«title»:»value1″, «text»:»value2″},
{«title»:»value3″, «text»:»value4″}
]
Although you can, in a simple case, to create a file initially with an open bracket [ and first data recordDo you copy? ‘,’.PHP_EOL.$new_json_rowWhen reading the file, but before decoding, json add at the end ] And then decode.But it looks like a crutch.Without knowing the original challenge, it’s hard to say anything. But perhaps you’d better get a normal SBS.

mysqli_query($CONNECT, «INSERT INTO ‘users’
VALUES (»,’$_POST[login]’,’$_POST[password]’,’$_POST[email]’,’NOW()'»)
Given the previous answer, I’d say it’s here. ‘users’ taken into skirts when the right thing ismysqli_query($CONNECT, «INSERT INTO users (col1, col2, col3, col4, col5)
VALUES (»,’$_POST[login]’,’$_POST[password]’,’$_POST[email]’,’NOW()'»)

Use prepared statments, so your query is vulnerable.Your mistake is probably on query because you’re using an accent on «users» !In any case, use the prepared statments you have an example of the code and the link of the documentation site:
https://www.php.net/manual/en/mysqli.prepare.php Code:if(empty($login) or empty($senha)):
$erros[] = «<li> O campo login/senha precisa ser preenchido </li>»;
else:
$sql = $mysqli->prepare(«SELECT login FROM usuarios WHERE login=»);
$sql-&gt;bind_param(«s», $login);

$sql-&gt;execute();

$resultado = mysqli_query($connect, $sql) or die(mysqli_error($connect)); //mysqli_query($connect, $sql) or die mysql_error();

if(mysqli_num_rows($resultado) &gt; 0):
$senha = md5($senha);
$sql = «SELECT * FROM usuarios WHERE login = ‘$login’ AND senha = ‘$senha'»;
$resultado = mysqli_query($connect, $sql);

if(mysqli_num_rows($resultado) == 1):
$dados = mysqli_fetch_array($resultado);
$_SESSION[‘logado’] = true;
$_SESSION[‘id_usuário’] = $dados[‘id’];
header(‘Location: home.php’);
else:
$erros[] = «&lt;li&gt; Usuário e senha incorretos &lt;/li&gt;»;
endif;

else:
$erros[] = «&lt;li&gt; Usuário inexistente &lt;/li&gt;»;

I recommend using in-memory database or slope as cli, preferably not php. https://www.sqlite.org/inmemorydb.html

This is a problem in solving class names. The cause of this you yourself said in the question: PHP versions are different in the development and the publishing server.A priori you only have two options: 1) Make your application run in the correct version of PHP — regardless of how this will be done; and 2) Adapt your application to run in version 5.4 of PHP.

When they have n values in one insert, these need to be separated by comma:insert into [table_name] (column_1, column_2, …)
values (value_1, value_2, …), (value_3, value_4, …)
In your code apparently you want to do this, you even make a substring to remove the comma after the foreach, but you forgot to concatenate the comma at the end of each set of values:'».$linha_bd[‘localizacao’].»‘)»;
Change to:'».$linha_bd[‘localizacao’].»‘),»;

Here’s the algorithm:Take the first unsettled top of the count.Nailing https://ru.wikipedia.org/wiki/%D0%9F%D0%BE%D0%B8%D1%81%D0%BA_%D0%B2_%D0%B3%D0%BB%D1%83%D0%B1%D0%B8%D0%BD%D1%83 or https://ru.wikipedia.org/wiki/%D0%9F%D0%BE%D0%B8%D1%81%D0%BA_%D0%B2_%D1%88%D0%B8%D1%80%D0%B8%D0%BD%D1%83 All the peaks achievable from it.Each of the peaks visited (including the original) is marked as (please for tautology) visited. If not all the tops were visited, I goto 1.For this algorithm, it will be convenient to establish a separate set of visits to the top. To mark the peaks in it as visited by the best number of spectaculars to the order number of the «storm» to which the top belongs. The number «sorrow» will increase by 1 in c. 1. It will also be convenient to track the completion point of the algorithm, as soon as all the peaks in it are marked as visited, the algorithm has finished its work.

One problem I’ve detected is that you’re concatenating the instruction wrong insert.Try to arrange for the following way$sqlCadastraTarefa=»Insert into Tarefas (nome_TAREFA, dataInicio_TAREFA, dataFim_TAREFA, «;
$sqlCadastraTarefa.=»descricao_TAREFA, prioridade_TAREFA, cor_TAREFA)»;
The way you concatenated would be getting as follows the instruction Insert into Tarefas (nome_TAREFA, dataInicio_TAREFA, dataFim_TAREFA, )(descricao_TAREFA, prioridade_TAREFA, cor_TAREFA)
Staying One ,) ( between the columns.The way I put it wouldInsert into Tarefas (nome_TAREFA, dataInicio_TAREFA, dataFim_TAREFA, descricao_TAREFA, prioridade_TAREFA, cor_TAREFA)
