我有一个填充数据库的表单,但在错误处理方面遇到了麻烦。我希望错误显示在同一pg的一个小的 pop 窗口中。

    <form id="form1" name="form1" method="post" action="mailform.php" onsubmit="MM_validateForm('Name','','R','Business Name','','R','Email Address','','R','How selling product','','R','Where did you hear about us','','R');return document.MM_returnValue">
<div style="color:#FF0000; text-align:center;"><?php if(!empty($_GET['err_msg'])){echo $_GET['err_msg'];} ?></div>
<fieldset>
<legend>Contact form</legend>
<p class="first">
<label for="name">First Name</label>
<input type="text" name="First Name" id="first_name" size="30" value="<?=htmlentities($profiledata['First_Name'])?>" />
</p>

<p class="first">
<label for="name">Last Name</label>
<input type="text" name="Last Name" id="last_name" size="30" value="<?=htmlentities($profiledata['Last_Name'])?>" />
</p>

<p>
<label for="name">Phone Number</label>
<input type="text" name="Phone Number" id="phone number" size="30" value="<?=$profiledata['Phone_Number']?>" />
</p>
<p>
<label for="email">Business Name</label>
<input type="text" name="Business Name" id="business name" size="30" value="<?=htmlentities($profiledata['Business_Name'])?>" />
</p>
<p>
<label for="email">Web Address</label>
<input type="text" name="Web Address" id="web address" size="30" value="<?=$profiledata['Web_Address']?>" />
</p>
<p>
<label for="email">Email</label>
<input type="text" name="Email Address" id="email address" size="30" value="<?=$profiledata['Email_Address']?>" />
</p>
<p>
<img src="CaptchaSecurityImages.php?width=100&height=40&characters=5" /><br />
<label for="security_code">Security Code: </label><input id="security_code" name="security_code" type="text" />
</p>
</fieldset>
<fieldset>
<p>
<label for="message">Describe how you plan on selling this product</label>
<textarea name="How selling product" id="How selling product" cols="30" rows="4"><?=htmlentities($profiledata['How_selling_product'])?></textarea>
</p>
<p>
<label for="message">Where did you hear about us?</label>
<textarea name="Where did you hear about us" id="Where did you hear about us" cols="30" rows="4"><?=htmlentities($profiledata['Where_did_you_hear_about_us'])?></textarea>
</p>
</fieldset>
<p class="submit"><button type="submit">Send</button></p>

<input name="mailform_address" type="hidden" value="email@address.com" />
</form>

return;
}

我会很乐意为您提供帮助,或者至少是朝正确的方向轻推。谢谢!

最佳答案

根据所需的“ pop ”类型,您可能需要实现一些客户端javascript,以显示格式正确的消息,该消息利用从服务器发回的消息。

我想看看是否使用JQuery。
