  2. Hi guys, I have a odd problem here. I'm a beginner and I have no idea what it can be.. 😑 ps. English is not my first language, so I hope you can understand... ☺️ In dropdown field below, I put in value property the ID column, but when it registers in the database, it saves as string type and not as integer. <?php $sql = "SELECT id, sigla FROM local ORDER BY sigla ASC"; $result = $conn->query($sql); ?> . . . <select name="local" class="form-control"> <option selected>Selecione...</option> <?php while($row = $result->fetch_assoc()){ echo "<option value=".$row['id'].">".$row['sigla']."</option>"; } ?> </select> . . . I used a var_dump() on ID to know what would happend, and it shows as string type. <pre> <?php $sql = "SELECT id, sigla FROM local ORDER BY sigla ASC"; $result = $conn->query($sql); $row = $result->fetch_assoc(); var_dump($row['id']); ?> </pre> Result: string(1) "5" This is the database: -- phpMyAdmin SQL Dump -- version 4.8.3 -- https://www.phpmyadmin.net/ SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO"; SET AUTOCOMMIT = 0; START TRANSACTION; SET time_zone = "+00:00"; /*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */; /*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */; /*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */; /*!40101 SET NAMES utf8mb4 */; -- -- Banco de dados: `arq` -- -- -------------------------------------------------------- -- -- Estrutura para tabela `local` -- CREATE TABLE `local` ( `id` int(11) NOT NULL, `SIGLA` mediumtext NOT NULL, `LOCAL` mediumtext NOT NULL, `TELEFONE` mediumtext NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=utf8; -- -- Fazendo dump de dados para tabela `local` -- INSERT INTO `local` (`id`, `SIGLA`, `LOCAL`, `TELEFONE`) VALUES (1, 'AAC', 'AAC', '2222-2222'), (2, 'DSV', 'DSV', '1111-1111'), (3, 'SCA', 'SCA', '3333-3333'); -- -- Índices de tabelas apagadas -- -- -- Índices de tabela `local` -- ALTER TABLE `local` ADD PRIMARY KEY (`id`); -- -- AUTO_INCREMENT de tabelas apagadas -- -- -- AUTO_INCREMENT de tabela `local` -- ALTER TABLE `local` MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=6; COMMIT; /*!40101 SET CHARACTER_SET_CLIENT=@OLD_CHARACTER_SET_CLIENT */; /*!40101 SET CHARACTER_SET_RESULTS=@OLD_CHARACTER_SET_RESULTS */; /*!40101 SET COLLATION_CONNECTION=@OLD_COLLATION_CONNECTION */; Thank you so much!!
  3. Hi guys, I'm beginning to learn PHP now, and i have too much doubts yet, so i would like some help. 😃 I want to delete a registry from table when i press the button "Apagar" like show in the picture below: When I press the button, it shows a message saying it was successfully deleted, but in fact it was not deleted in the DB. The message: Notice: Undefined index: id in .../teste_tabela3/deletar_produto.php on line 11 What did i do wrong in my code? code from "deletar_produto.php" file: <?php include_once 'cabeçalho.php'; include_once 'conexao.php'; $id = $_POST['id']; if(isset($_POST['apagar'])){ $sql = "DELETE FROM produtos WHERE id='$id'"; $result = mysqli_query($conn, $sql); if($conn->query($sql) === TRUE) echo "<br/><br/><span>O registro foi deletado com sucesso...!!</span>"; }else{ echo "<p>Não foi possivel apagar o registro....!!</p>"; } $conn->close(); ?> And this is code of "listar_produtos.php" file: <?php  include_once 'cabeçalho.php'; include_once 'conexao.php'; ?> <div class="d-flex mx-2 my-2"> <div class="mr-auto p-2"> <h2 class="display-4 titulo">Lista de Produtos</h2> </div> </div> <?php $sql = "SELECT id, produto, valor FROM produtos"; $result = $conn->query($sql); ?> <!--------------------------------------------TABELA--------------------------------------------> <div class="table-responsive"> <table class="table table-bordered table-hover table-striped"> <thead> <tr> <th>ID</th> <th>Produto</th> <th>Valor</th> <th>Ações</th> </tr> </thead> <?php if ($result->num_rows > 0) { echo "<tbody>"; while($row = $result->fetch_assoc()) { echo "<tr>"; echo "<td>" .$row['id'] ."</td>"; echo "<td>" .$row['produto']. "</td>"; echo "<td>" .$row['valor']. "</td>"; echo "<td>"; echo "<form action='deletar_produto.php' method='post'>"; echo "<button type='submit' class='btn btn-outline-primary' name='editar'>Editar</button> &nbsp;"; echo "<button type='submit' class='btn btn-outline-primary' name='apagar'>Apagar</button>"; echo "</form>"; echo "</td>"; echo "</tr>"; } } else { echo "0 results"; } ?> </tbody> </table> <?php $conn->close(); include_once 'rodape.php'; ?> Thank you so much!!
