Php和sqlite注册表

我是php和sqlite的新手，我试图修改网站的注册表单。我做了我认为所有必要的更改，但我现在无法使其工作，因为当我使用电子邮件注册它时告诉我它已经存在。该表单之前使用了用户名，并检查用户名是否已存在。如果是，则显示消息。现在我不想使用用户名，但要注册电子邮件，即使数据库是空的，它总是告诉我电子邮件已经存在。我只留下了注册电子邮件，以便更容易理解。但即使这样，问题仍然存在。

我认为在检查数据库时存在问题，但我不知道问题出在哪里。我不太了解php页面之间的流程，所以如果有人可以帮我澄清究竟发生了什么，我会很感激。这是注册页面的代码。

Participate.php:

<hr class="structure" />
<h1 class="out">Main content</h1>
<div class="eb1"> 
  <!--TYPO3SEARCH_begin-->
  <h2 class="out">Topinformationen</h2>
  <!--TYPO3SEARCH_end--> 
</div>
<div class="eb2"> 
  <!--TYPO3SEARCH_begin-->
  <h2>Participate</h2>
<p>Please register.</p>
  <!-- ###LOGIN_FORM### -->
<div class="box big form">

<form id="participateForm" action="#" target="_top" onSubmit="return checkform();" method="post" name="participate">
    <fieldset class="nolegend">
        <legend>Particpate</legend>
        <div>
            <label for="email">
                <span> Email:* <?php echo isset($_POST['email']) ? '<strong>The email &ldquo;' .$_POST['email']. '&rdquo; already exists. </strong>' : ''; ?></span><input type="email" name="email" required/>
            </label>
        </div>
    </fieldset>
    <div class="morelink">
        <p><input type="submit" name="submit" value="Participate" onclick="show('form'); return FALSE;"/></p>
    </div>
</form>
</div><!-- box big form -->
</div>

因此，如果我在您点击“参与”按钮时理解正确，则该页面会自动调用（action =＆＃34;＃＆＃34;），并将该电子邮件作为帖子变量。问题是这个特定页面上没有任何内容使用该变量，所以我想这段代码正在重新加载index.php页面，该页面以这样的方式开始。

index.php:

<?PHP
    //Session wird gestartet
    session_start();
        //Includ PHP functions
    @include("./data/php/functions.php");
        //Funktionen werden ausgeführt
    if(isset($_GET['do']))
    {
    if($_GET["do"]=="logout"){
        logout();
     }
    }
     else if (!empty($_GET["email"])&& !session()){
        login($_GET["email"]);
     }
     if(postvar("submit")=="login" && !session()){
         login(0,0);
     }
     else if (postvar("submit")=="participate" && !session()){
         register();
     }
     else if (postvar("submit")=="emote" && session()){
         saveMood();
     }

?>

在这个functions.php中，index.php页面中包含的代码是访问数据库的函数。所以这些功能中有两个就是这些。

functions.php:

function postvar($var)
{
    if (isset($_POST[$var])){
    $erg = $_POST["$var"];
    $erg = trim($erg);
    }
    else 
    $erg=NULL;
    return $erg;
}

function register()
{
    global $open, $settings, $db_usr;

    $email = postvar("email");

    //if($privacy && $terms)
    if(TRUE)
    {
        $query = "SELECT * FROM usr_data WHERE email='".$email."'";
        $res_usr = $db_usr->prepare($query);
        $res_usr->execute();
        $count=$res_usr->fetchColumn();

        if($count!=1){

        $query ="INSERT INTO usr_data (email, regtime, status, sessionID) VALUES ('".$email."', '".time()."','0', 'new')";
        $db_usr->query($query);

        header("Location: ".$settings["Main"]."?open=Login&info=1");
        }
        else
        {
        //$open="Login_Failed";
        }
    }
}

所以我认为它发生的是这个，如果有人告诉我，我是否完全迷失了，或者我是否需要将其他部分代码澄清，我将不胜感激。所以，visit.php通过发送此post变量的电子邮件调用自己。不知何故，我并不确切地知道如何调用functions.php代码，这个寄存器函数用于检查电子邮件是否存在，如果不存在，则将其添加到数据库中。问题是它无法正常工作。此代码之前有效，而不是使用用户名的电子邮件。那时的注册确实有效。

顺便说一下，在Participate.php代码中调用的checkform（）函数就是这样做的。

function checkform()
  {
                if (document.participate.email.value ==  "")
                 {
                      alert('Please enter an email.');
                      document.participate.email.focus();
                      return false;
                }

  }
