当点击提交按钮时，我正在尝试获取错误消息，但仅从textfield获取消息，而不是从textarea获取消息。这是我的密码。问题是，如果我提交没有textarea的字段，它将显示成功消息。
if(empty($_POST)===false)
{
if(empty($_POST['offered'])===true||($_POST['description'])===true)
{
?>
<div class="alert alert-warning alert-dismissible text-center" role="alert">
<span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span>Add some offers and descriptions
</div>
<?php
}
else
{
$title = $_POST['offered'];
$offer = $_POST['description'];
$data = array(
$page_id,
$title,
$offer
);
if ($data)
{
$add = add_data($data);
header('location:hotel1_galery.php?page_id=1 && msg=Add Offers Successfully');
}
else
if (!empty($_POST['offered']) && !empty($_POST['description']))
{
?>
<div class="alert alert-danger alert-dismissible text-center" role="alert">
<span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span><?php
echo "Add offers and descriptions "; ?></div>
<?php
}
}

您尚未在以下行中检查空：
更改此项：
if(empty($_POST['offered'])===true||($_POST['description'])===true)
至：
if(empty($_POST['offered'])||empty(trim($_POST['description'])))
<?php
if(!empty($_POST))
{
if(empty($_POST['offered']) || empty($_POST['description']))
{
?>
<div class="alert alert-warning alert-dismissible text-center" role="alert">
<span class="glyphicon glyphicon-exclamation-sign" aria-hidden="true"></span>Add some offers and descriptions
</div>
<?php
}
else
{
$title=$_POST['offered'];
$offer=$_POST['description'];
$data=array($page_id,$title,$offer);
if($data)
{
$add=add_data($data);
header('location:hotel1_galery.php?page_id=1 && msg=Add Offers Successfully');
