我已经将表单添加到管理面板中，其中包含yes（1）和no（0）选项。PHP：仅当数据库值等于X时才显示表单
我已经更改了Db，因此在提交时，值将被添加到Db值为“seller”1或0的工作正常。
我在我的网站上有一个窗体。如果卖家的Db值为1，我只希望它显示给登录的人。如果它们的值为0，我想打印一条消息。
我猜我需要查询数据库，然后构造一个函数，并将其应用于页面中的表单代码要显示它，如果满足条件“1”？
我尝试过搜索，但无法掌握如何构建它。
我使用如果我的解决方案在这里else条件：
<?php
$userLoggedIn = $_SESSION['userName'];//session created while login is stored in variable
//Search table `tbl` for field `SELLER` where field `user` matches with loggedin user
$searchSeller = mysql_query("SELECT `SELLER` from `tbl` WHERE `user`='$userLoggedIn'");
$searchSellerArray = mysql_fetch_array($searchSeller);
//Setting variable to be used in css depending on value in table
if($searchSellerArray['seller']==1){
$displayForm="block";//displays form
$displayMessage="none";//hides message
}
elseif ($searchSellerArray['seller']==0){
$displayForm="none";//hides form
$displayMessage="block";//displays message
}
?>
<form style="display:<?php echo $displayForm;?>;">
//Form content goes here...
</form>
<p style="display:<?php echo $displayMessage;?>;">
//Message content goes here
</p>
<?php
// insert your DB Data
$user = "";
$pass = "";
$host = "";
$dbdb = "";
$connect = mysqli_connect($host, $user, $pass, $dbdb);
if(!$connect)
{
trigger_error('Error connection to database: '.mysqli_connect_error());
}
mysqli_set_charset($connect, 'utf8');
$query = mysqli_query($connect, "SELECT `seller` FROM `nameTable` WHERE `user` = 'userName'");
$record = mysqli_fetch_array($query);
if($record['seller'] == 1){
echo "Seller is 1";
}else{
echo "Seller is 0";
}
?>
我试图给出的PHP和无法得到它在所有的工作。所以我认为这可能会更有帮助发布整个PHP脚本。
我想，如果有人没有“卖方”的设置为1的数据库中的状态，而是一个错误信息下方表单，根本无法加载。
