Question

我试图进行调查问卷，但它只是没有连接我的数据库，这很奇怪，因为在其他php几乎相同的连接工作。你能帮忙吗？

<?php
if (isset($_POST['pohlavi'])) {
    if (!isset($_POST['platforma']) || !isset($_POST['ano']) || !isset($_POST['nazor']) || $_POST['platforma'] = "" || $_POST['nazor'] = "" || $_POST['ano'] = "") {
        die("Nastala chyba, musíte vyplnit všechny pole! Dotazník nebyl odeslán.");
    } else {
        $conn = new mysqli('localhost', 'adress', 'password', 'czseznamka');
        $conn->query("INSERT INTO dotaznik (pohlavi, platforma, ano, nazor) VALUES ('" . $_POST['pohlavi'] . "', '" . $_POST['platforma'] . "', '" . $_POST['ano'] . "' , '" . $_POST['nazor'] . "');");
        echo '<span style="text-align:center;color:green;font-size:30px;"> Dotazník odeslán</span>';
    }
}
?>

尝试使用以下启用错误

if (isset($_POST['pohlavi'])) {
     if (!isset($_POST['platforma']) || !isset($_POST['ano']) || !isset($_POST['nazor']) || $_POST['platforma'] = "" || $_POST['nazor'] = "" || $_POST['ano'] = "") {
         mysqli_report(MYSQLI_REPORT_STRICT);

     try {
         $connection = new mysqli('localhost', 'root', '', 'dbname') ;
         $connection->query("INSERT INTO dotaznik (pohlavi, platforma, ano, nazor) VALUES ('" . $_POST['pohlavi'] . "', '" . $_POST['platforma'] . "', '" . $_POST['ano'] . "' , '" . $_POST['nazor'] . "');");

      } catch (Exception $e ) {
         echo "Service unavailable";
         echo "message: " . $e->message;   
         exit;
      }
   }
}
