Flaviaac 0 Posted August 30, 2019 Report Share Posted August 30, 2019 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!!

justsomeguy 1,135 Posted August 30, 2019 Report Share Posted August 30, 2019 Everything that the browser submits is a string, there is no data type information that gets submitted. It it just a name, and a string value. Quote Link to post Share on other sites
Ingolme 1,022 Posted August 31, 2019 Report Share Posted August 31, 2019 Everything that comes from the database is also a string. If you want it to be an integer you have to cast it. Quote Link to post Share on other sites
Flaviaac 0 Posted September 2, 2019 Author Report Share Posted September 2, 2019 Ah, got it @justsomeguy. @Ingolme I tried using intval() to convert it, seems to worked. Thanks guys! Quote Link to post Share on other sites
