在PHP中使用表單的最佳做法是什麼？你可以在表單中使用OOP PHP嗎？

Question

現在我一直在爲評論部分，登錄部分和發送電子郵件的網站創建表單。我使用的代碼來自我學習的教程，其中包含太多的HTML。這是我知道如何創建表單並驗證數據的唯一途徑。我想問問是否有更好的方式來創建表單，以及是否有方法在OOP PHP中創建表單？我想學會超越基本的東西到面向對象。

這是我使用的時刻代碼的例子：

<?php include 'includes/validation.php' ?> 

<!-- START CONTENT --> 
    <div id="mainContent"> 
    <div class="portContentTop"><img src="graphx/image.gif" alt="" border="0" /></div> 
    <div class="portContent"> 
    <img src="graphx/image.gif" alt="Contact Me" border="0" /><h1 class="hidden">Contact</h1><br /> 
      If you wish to contact me, please fill out the form or send me an email at <a href="mailto:user@gmail.com">user@gmail.com</a>. 
    <br /> 
      <? if(isset($_POST['send'])&& (!validateName($_POST['name']) || !validateEmail($_POST['email']) || !validateMessage($_POST['message']))):?> 
      <div id="errorMessage"> 
      <ul> 
       <? if(!validateName($_POST['name'])):?> 
       <li>Your name must be 4 characters long.</li> 
        <? endif ?> 
        <? if(!validateEmail($_POST['email'])):?> 
        <li>Your email address has an error.</li> 
    <? endif ?> 
        <? if(!validateMessage($_POST['message'])):?> 
        <li>Your comment must be 10 characters long.</li> 
        <? endif ?> 
      </ul> 
      </div> 
      <?php elseif(isset($_POST['send'])):?> 
      <?php 
    $name=strip_tags($_POST['name']); 
    $email=strip_tags($_POST['email']); 
    $message=strip_tags($_POST['message']); 
    $subject= "A message from me was submitted by ".$name." "; 
    $sentto= "user@gmail.com"; 

    $contents = "Name: ".$name. "\n". 
     "Email: ".$email. "\n". 
     "Message: ".$message. "\n"; 

    mail($sentto, $subject, $contents); 

    ?> 
      <div id="errorMessage"> 
       <ul class="errorValid"> 
       <li>Your message has been sent.</li> 
      </ul> 
      </div> 
      <? endif?> 
    <form method="post" id="customForm" name="customForm" action="" > 
      <table border="0" align="center" cellpadding="0" cellspacing="0" style="padding:0px; margin:0px;"> 
        <tr valign="top"> 
        <td align="center"><img src="graphx/h_name.gif" border="0" alt="Name:" /></td> 
        <td><input class="contactInput" id="name" name="name" type="text" size="30" /></td> 
        </tr> 
        <tr valign="top"> 
        <td align="center"><img src="graphx/h_email.gif" border="0" alt="Email:" /></td> 
        <td><input class="contactInput" id="email" name="email" type="text" size="30" /></td> 
        </tr> 
        <tr valign="top"> 
        <td align="center"><img src="graphx/h_comments.gif" border="0" alt="Comments:" /></td> 
        <td><textarea id="message" name="message" cols="30" rows="15" wrap="off" class="contactInput2"></textarea></td> 
        </tr> 
        <tr valign="top"> 
        <td></td> 
        <td align="left"><input id="send" name="send" type="submit" value="Submit" ></td> 
        </tr> 
       </table> 
      </form> 
</div> 
<!-- END CONTENT -->

是的，有創造形式的「好」的方式。你可能想看看框架是如何流行的。

下面是Zend框架 http://www.framework.zend.com/manual/en/zend.form.quickstart.html

$form = new Zend_Form(); 
    $form->setAction('/user/login') 
     ->setMethod('post'); 

    // Create and configure username element: 
    $username = $form->createElement('text', 'username'); 
    $username->addValidator('alnum') 
      ->addValidator('regex', false, array('/^[a-z]+/')) 
      ->addValidator('stringLength', false, array(6, 20)) 
      ->setRequired(true) 
      ->addFilter('StringToLower'); 

    // Create and configure password element: 
    $password = $form->createElement('password', 'password'); 
    $password->addValidator('StringLength', false, array(6)) 
      ->setRequired(true); 

    // Add elements to form: 
    $form->addElement($username) 
     ->addElement($password) 
     // use addElement() as a factory to create 'Login' button: 
     ->addElement('submit', 'login', array('label' => 'Login'));
