Flaviaac Posted August 30, 2019 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 Posted August 30, 2019 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. Link to comment Share on other sites More sharing options...
Ingolme Posted August 31, 2019 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. Link to comment Share on other sites More sharing options...
Flaviaac Posted September 2, 2019 Author Share Posted September 2, 2019 Ah, got it @justsomeguy. @Ingolme I tried using intval() to convert it, seems to worked. Thanks guys! Link to comment Share on other sites More sharing options...
