我的工作用PHP编写的一个简单的联系表上的几乎一切设置为我想它是除了现在所有验证错误都在我的窗体顶部一个div显示，我想改变下面让他们靠近可能导致错误的表单字段中显示，但我不知道如何做到这一点，所以我已经走到了专家为一些建议代码。
PHP验证例程
$frm_valid = new Validate();
if(isset($_POST['submit'])){
$rules=array(
array('Type'=>'Required','Var'=>$_POST['name'],'Msg'=>'Name field is required.'),
array('Type'=>'Required','Var'=>$_POST['email'],'Msg'=>'Email address field is required.'),
array('Type'=>'Email','Var'=>$_POST['email'],'Msg'=>'Your email address format is invalid.'),
array('Type'=>'Required','Var'=>$_POST['subject'],'Msg'=>'Subject field is required.'),
array('Type'=>'Required','Var'=>$_POST['message'],'Msg'=>'Message field is required.'),
);
$result = $frm_valid->Valid($rules);
if(is_array($result)){
// Print validation errors (if any)
echo('<div"><b>The form cannot be submitted until the following errors are corrected.</b><ul>');
foreach($result as $key=>$val){
echo '<li>'.$val.'</li>';
}
echo('</ul></div><br />');
}
else {
// Do something else.
}
}
HTML表单
<form action="<? echo htmlentities($_SERVER['PHP_SELF']); ?>" method="post">
<input type="text" name="name" value="" /> <br />
<input type="text" name="email" value="" /> <br />
<input type="text" name="subject" value="" /> <br />
<textarea name="message" cols="80" rows="7"></textarea> <br />
<input type="submit" name="submit" value="Send" />
</form>
你需要改变整个代码这个！ 结构，也许是这样的：
<form action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>">
<ul>
<li>
<label>
<span>Name</span>
<input type="text" name="name" />
<small class="errorText"><?php echo ($_POST["name"] == "") ? "This field is required" : ""; ?></small>
</label>
</li>
<li>
<label>
<span>Email</span>
<input type="text" name="email" />
<small class="errorText"><?php echo ($_POST["email"] == "") ? "This field is required" : ""; ?></small>
</label>
</li>
<li>
<label>
<span>Subject</span>
<input type="text" name="subject" />
<small class="errorText"><?php echo ($_POST["subject"] == "") ? "This field is required" : ""; ?></small>
</label>
</li>
<li>
<label>
<span>Message</span>
<textarea name="message" cols="80" rows="7"></textarea>
<small class="errorText"><?php echo ($_POST["message"] == "") ? "This field is required" : ""; ?></small>
</label>
</li>
<li>
<input type="submit" name="submit" value="Send" />
</li>
</ul>
</form>
和CSS的一样：
* {font-family: Segoe UI, Tahoma;}
h1 {font-weight: bold; font-size: 14pt; padding: 5px 0; margin: 5px 0; border: 1px solid #999; border-width: 1px 0;}
input[type='submit'] {padding: 5px 20px; cursor: pointer;}
ul, li {display: block; list-style: none; margin: 0; padding: 0;}
ul li {padding: 5px 0;}
ul li label span {display: block; cursor: pointer;}
ul li label .errorText {color: #f00; font-weight: bold; vertical-align: top;}
ul li label textarea {width: 300px;}

在PHP错误处理
保持一个错误变量为每个字段。 说，
<?php
$error = array(
"name" => "",
"email" => "",
"subject" => "",
"message" => ""
);
?>
与错误更新它们，下面显示出来。
<?php
if (empty()$_POST["email"])
$error["email"] = "Email is required!";
elseif (!isEmail($_POST["email"]))
$error["email"] = "Not a Valid Email!";
?>
如果没有错误，这将是空的，用户不会看到错误消息。 在你的表单代码，您只是需要更新这种方式：
<small class="errorText"><?php echo $error["name"]; ?></small>
<small class="errorText"><?php echo $error["email"]; ?></small>
其中，在后端，在$error["email"]将要么"This field is required"或"Not a valid email address!" 。
您可以使用下面的方法，如果你的每一个领域都有一个错误：
<input name='myfield'>
@if ($errors->has('myfield'))
<span style="color:red;">
{{ $errors->first('myfield') }}
</span>
@endif
