一个很简单的php留言板。。。。搭建在sae上的。。。

我在sae上搭建了一个个人简历的页面: 有兴趣的可以访问  http://671coder.sinaapp.com/

在做下面一个简单的留言板的时候,卡了我很久,虽然完全没用过php。。但是还是最后勉强写出来了。。。

主页面html是这样写的:

    <div class="row row-contact" id="contact_row" style="display: block">
      <article>

        <h2 class="section-title">Contact Me</h2>

        <p>This block can be hidden and only shown in <a class="zoom-html">a popup</a>.</p>

        <div class="wrap-contact-form">
          <form id="contacts" class="contact-form" action="/db/submitform.php" method="post">
            <table class="info">
              <tr>
                <th><label for="contact_name">Name</label></th>
                <td><input type="text" class="input-text" name="contact_name" id="contact_name" value="" maxlength="10"></td>
              </tr>
              <!-- start spam protection 
              <tr class="spam-protection">
                <th><label>E-mail</label></th>
                <td><input type="text" name="email" value=""></td>
              </tr>
               end -->
              <tr>
                <th><label for="contact_code">Security code</label></th>
                <td><input type="text" class="input-text" name="contact_code" id="contact_code" maxlength="4"></td>
              </tr>
			  
              <tr>
                <th><label for="contact_message">Your Message</label></th>
                <td><textarea id="contact_message" name="contact_message" maxlength="200"></textarea></td>
              </tr>
              <tr>
                <th></th>
                <td>
                  <input type="submit" class="input-submit" name="contact_send" value="Send">
                  <div class="on-success">
                    Thank You. The message was sent.
                  </div>
				  <!--
                  <div class="on-error">
                    A technical error occured. Message was not delivered. Please contact me over e-mail.
                  </div>
				  -->
                </td>
              </tr>
            </table>
          </form>
        </div>

      </article>
    </div>

验证码功能暂时还没有实现。。。

后台的php是这样写的:

<?php
	
	$name = $_POST['contact_name'];
	$message = $_POST['contact_message'];

	if (strlen($name) == 0 || strlen($message) == 0) {
		?><script>
			alert("Sorry, your name and your message can not be empty.");
			window.history.back(-1);
		</script><?
	}
	
	$m_notchar="$#@!%&*?<>";	

	$mysql = new SaeMysql();
	
	$judge = true;
	for ($i=0; $i<10; $i++) {
		if (strpos($name, substr($m_notchar, $i, 1)) || strpos($message, substr($m_notchar, $i, 1)))
			$judge = false;
	}
	if( $mysql->errno() != 0 ) {
		die( "Error:" . $mysql->errmsg() );
	} else if (!$judge) {
		?><script>alert("Sorry, your message has illegal characters, please re-enter checked.");</script><?
	} else {
		$sql = &q
