Question

此准备好的插入语句的一部分有效，而另一部分则无效，并且我看不到原因，因为我没有收到错误。

我尝试了不同的选择，甚至mysqli也没有赢。 PDO确实包含语句$ dbh-> setAttribute（PDO :: ATTR_ERRMODE，PDO :: ERRMODE_EXCEPTION）

try {
    $dbh = new PDO("mysql:host=localhost;dbname=project","root","");
    $dbh->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

    echo "Connected successfully";

    if ( $_SERVER['REQUEST_METHOD'] == 'POST' &&  isset($_POST['submit']));

    if(
        !empty($_POST['skill_level_1'])
        && !empty($_POST['skill_level_2'])
        && !empty($_POST['skill_level_3'])

        && isset($_POST['skill_1'])
        && isset($_POST['skill_experience_1'])
        && isset($_POST['skill_2'])
        && isset($_POST['skill_experience_2'])
        && isset($_POST['skill_3'])
        && isset($_POST['skill_experience_3'])

    ){

        foreach($_POST['skill_level_1'] as $selected) {
            $GLOBALS['skill_level_1'] = $selected;
        }
        foreach($_POST['skill_level_2'] as $selected) {
            $GLOBALS['skill_level_2'] = $selected;
        }
        foreach($_POST['skill_level_3'] as $selected) {
            $GLOBALS['skill_level_3'] = $selected;
        }
        $skill_1 = strip_tags(trim($_POST['skill_1']));
        $skill_experience_1 = strip_tags(trim($_POST['skill_experience_1']));
        $skill_2 = strip_tags(trim($_POST['skill_2']));
        $skill_experience_2 = strip_tags(trim($_POST['skill_experience_2']));
        $skill_3 = strip_tags(trim($_POST['skill_3']));
        $skill_experience_3 = strip_tags(trim($_POST['skill_experience_3']));

        $stmt = $dbh ->prepare("INSERT INTO dbtable
(
skill_level_1, skill_level_2, skill_level_3,
skill_1, skill_experience_1, 
skill_2, skill_experience_2, 
skill_3, skill_experience_3
)VALUES(
:skill_level_1, :skill_level_2, :skill_level_3,
:skill_1, :skill_experience_1, 
:skill_2, :skill_experience_2, 
:skill_3, :skill_experience_3
)");

// $stmt->execute(array(':skill_level_1' => $skill_level_1, ':skill_level_2' => $skill_level_2, ':skill_level_3' => $skill_level_3));

        $stmt->bindParam(':skill_level_1',$skill_level_1);
        $stmt->bindParam(':skill_level_2',$skill_level_2);
        $stmt->bindParam(':skill_level_3',$skill_level_3);

        $stmt->bindParam(':skill_1',$skill_1);
        $stmt->bindParam(':skill_experience_1',$skill_experience_1);

        $stmt->bindParam(':skill_2',$skill_2);
        $stmt->bindParam(':skill_experience_2',$skill_experience_2);

        $stmt->bindParam(':skill_3',$skill_3);
        $stmt->bindParam(':skill_experience_3',$skill_experience_3);

        $stmt->execute();

        echo "Success";

    }//end if

}
catch(PDOException $e)
{
    echo "Connection failed: " . $e->getMessage();
}

因此，它适用于部分Skill_level_1，skill_level_2，skill_level_3（复选框）。但是输入框不起作用。我认为带走标签可能会有所作为，但事实并非如此。我尝试了mysqli连接和语句，但也不起作用。

谢谢你们，我发现了这个问题。我在输入字段的HTML名称中有一个大写字母。

我还发现它有助于对数据库中的列进行排序，以匹配写入其中的PHP的顺序。这使我能够返回并再次检查HTML。
