Question

我试图将数据插入到我的表中。但它显示了其他部分。我无法插入数据。请帮忙。我的价值观名称是＆＃39; name＆＃39;，＆＃39; mail＆＃39;和＆＃39; pass＆＃39;。如在第二个查询中。

    <?php
    if(array_key_exists('name', $_POST) AND array_key_exists('mail', $_POST) 
AND array_key_exists('pass', $_POST)) {
        if($_POST['name'] == "") echo "<p>Name is required</p>";
        if($_POST['mail'] == "") echo "<p>Mail is required</p>";
        if($_POST['pass'] == "") echo "<p>Password is required</p>";

        if($_POST['name'] != "" AND $_POST['mail'] != "" AND $_POST['pass'] 
!= ""){

            $link=mysqli_connect("localhost", "root", "", "mydata");
            if(mysqli_connect_error()) echo "Couldn't connect to server, 
Please try again later.";
            else {

                $query = "SELECT `id` FROM TABLE1 WHERE `mail` = 
'".mysqli_real_escape_string($link, $_POST['mail'])."'";
                if($result = mysqli_query($link, $query)) {
                  $row = mysqli_fetch_row($result);
                    if($row != "") echo "Email already taken";
                    else {
                        $query = "INSERT INTO `table1` 
('name','mail','password') VALUE ('".mysqli_real_escape_string($link, 
$_POST['name'])."','".mysqli_real_escape_string($link, 
$_POST['mail'])."','".mysqli_real_escape_string($link, $_POST['pass'])."')";
                        if(mysqli_query($link, $query)) echo "yes";
                        else echo "nooo";
                    }
                }        
            }
        }
    };
?>

为什么不在代码中添加mysqli_error（）..以查看无法插入的原因。

MySQL查询。无法插入数据
