php kullanıcı girişi doğrulamak için çalışıyoruz

3 Cevap php

Ben php kullanıcı girişi doğrulamak için çalışıyorum. Değerler null olup olmadığını Bu kod kontrol edecektir. Null ise, bu girişin null değerleri için kullanıcı gerektirir. Ne zaman bu önce gelen html biçiminde tüm metin kutuları. Bu kod düğmesini tıklayın ve Gönder düğmesine mysql veritabanına girilen verileri kaydetmek gösterecektir. Ama sorun kaydedilir değeri sıfır sıfır ve sıfır olduğunu, ne bu neden olabilir?

Bu genellikle PHP formlar ve doğrulamaları ile başa nasıl. Ben bu yüzden sadece yöntemini gösteren yaşıyorum, yeniden biçim tam kod için gitmiyorum.

Live example: http://kopli.pri.ee/stackoverflow/2351193.php

Full version of the code:*

<?php

function is_valid_email ($email) {
    if(!preg_match('/^([a-z0-9])(([-a-z0-9._])*([a-z0-9]))*\@([a-z0-9])' . '(([a-z0-9-])*([a-z0-9]))+' . '(\.([a-z0-9])([-a-z0-9_-])?([a-z0-9])+)+$/i', $email)) {
        return true;
    } else {
        return false;
    }
}

if ($_POST['trigger']) {
    $p_name = $_POST['name'];
    $p_email = $_POST['email'];

    if (empty($p_name)) {$posting_errors[] = 'Name is missing!';}
    if ($p_name and strlen($p_name) < 3) {$posting_errors[] = 'Name is too short!';}
    if (empty($p_email)) {$posting_errors[] = 'Email is missing!';}
    elseif (is_valid_email($p_email)) {$posting_errors[] = 'Email is incorrect!';}

    if ($posting_errors) {
        $posting_message = '<div class="error_message">' . implode('<br />', $posting_errors) . '</div>';
    } else {
        $posting_message = '<div class="success_message">Great success!</div>';
    }
}

?>

            <label>Name:</label><input name="name" type="text" value="<?php echo ($_POST['name'] ? $_POST['name'] : '') ?>" /><br />
            <label>Email:</label><input name="email" type="text" value="<?php echo ($_POST['email'] ? $_POST['email'] : '') ?>" /><br />
            <input type="submit" value="Submit" />
        </form>
    </div>

</html>

Bunu yapmak için daha iyi bir yolu aslında "isset ()" gibi bir şey kullanarak $ _POST dizi değerini kontrol etmek olabilir.

örneğin

if(!isset($_POST['whatever']))

Ayrıca, beklenen değerlerin hiçbiri sıfır olabilir eğer o zaman her zaman ekleyebilirsiniz

if(empty($WHATEVER)||$WHATEVER==0)

*** P.S. Gordon belirtildiği gibi, size DB şema büyük ölçüde bize, size daha kesin bir cevap vermek yardımcı olacaktır ne DB ve bir fikir içine bilgi eklemek için kullandığınız kod sağlamak durumunda

İyi Şanslar!

En kolay ve en iyi şekilde otomatik olarak sunucuya göndermeden önce formun verilerini doğrular, hangi formlar için jQuery doğrulama kullanmaktır. Ben daha sonra sunucuya şeyleri doğrulayarak bunu kullanıyor gibi yapın
