I have a problem regarding the return of the information of the database in php, I have two tables, one tb_regiao, with the Brazilian states and another, tb_representante with the representatives in each state.

Below is the part with the select:

 <form class="ajs-form-representante" method="GET" action="pesquisar_representantes_art_ferro_moveis_fibra_sintetica.php">
            <select type="text" name="pesquisar" >
                <option class="lista-cidade" value="" selected="selected">Escolha a Região</option>
                <?php require_once ("ajs-script-php/selecta_cidade.php");?>
            </select>
            <input type="submit" value="BUSCAR">
        </form>

The script to select the region is this below:

<?php
require_once("ajs-adm/conexao/conecta.php");

$pesqu = $_GET["pesquisar"];
$listar = $conexao->prepare('SELECT * FROM tb_regiao WHERE regiao LIKE "%'.$pesqu.'%" LIMIT 27');
$listar->execute();
while ($exibe = $listar->fetch()){
    $nome_cidade = utf8_encode($exibe['regiao']);
    $nome_id = utf8_encode($exibe['id_id_reg']);
    echo "<option  class='$nome_id'>$nome_cidade</option>";
}

The page code to display the result is as below:

        <section class="ajs-section-rs-a">
            <?php
                $pesquisar = $_GET['pesquisar'];
                $result_repres = "SELECT * FROM tb_representante WHERE estado LIKE '%".$pesquisar."%' LIMIT 1";
                $result_resul_repres = mysqli_query($conect, $result_repres);
                   while($rows_repres = mysqli_fetch_array($result_resul_repres)){
                       echo "<p><b>Representante:</b> ".utf8_encode($rows_repres['nome_rp'])."</p>";
                       echo "<p><b>E-mail:</b> ".utf8_encode($rows_repres['email'])."</p>";
                       echo "<p><b>Celular:</b> ".utf8_encode($rows_repres['cel_a'])."</p>";
                       echo "<p><b>Celular:</b> ".utf8_encode($rows_repres['cel_b'])."</p>";
                       echo "<p><b>Telefone Fixo:</b> ".utf8_encode($rows_repres['tel_fixo'])."</p>";
                       echo "<p><b>Empresa:</b> ".utf8_encode($rows_repres['nome_empresa'])."</p>";
                       echo "<p><b>Endereço:</b> ".utf8_encode($rows_repres['rua'])."</p>";
                       echo "<p><b>Bairro:</b> ".utf8_encode($rows_repres['bairro'])."</p>";
                       echo "<p><b>Cidade:</b> ".utf8_encode($rows_repres['cidade'])."</p>";
                       echo "<p><b>Cep:</b> ".utf8_encode($rows_repres['cep'])."</p>";
                       echo "<p><b>Estado:</b> ".utf8_encode($rows_repres['estado'])."</p>";
                   }
            ?>
        </section>

Below is the tb_regiao table:

--

CREATE TABLE 'tb_regiao' (
  'id_reg' int(11) NOT NULL,
  'id_id_reg' varchar(2) COLLATE utf8_unicode_ci NOT NULL,

When I click to fetch the result, only the second record is returned, it does not show the first record and no other record.

I found the error, with this hint of yours, in the script to select the region, I put class = '$ id_id', when you wrote above, 'put the value' I looked at and changed to 'value =' $ id ' ", and ready, it ran normal, anyone who wants to use the code just change that runs 100% '

this is the corrected script

<?php
require_once("ajs-adm/conexao/conecta.php");

$pesqu = $_GET["pesquisar"];
$listar = $conexao->prepare('SELECT * FROM tb_regiao WHERE regiao LIKE "%'.$pesqu.'%" LIMIT 27');
$listar->execute();
while ($exibe = $listar->fetch()){
    $nome_cidade = utf8_encode($exibe['regiao']);
    $nome_id = utf8_encode($exibe['id_id_reg']);
    echo "<option  value='$nome_id'>$nome_cidade</option>";
}
