将主题设置为控制面板的主要主题（控制面板 - ＆gt;配置 - ＆gt;门户网站设置 - ＆gt;显示设置 - ＆gt;外观和感觉）后，没有选项可以选择我的任何颜色方案带有主题，
如何编写插件才能选择配色方案？

Thanks guys i was able to solve this by adding JavaScript Code (<?php
if(isset($_GET['action']) && $_GET['action']=="add")
{
$id=intval($_GET['id']);
if(isset($_SESSION['cart'][$id])){
$_SESSION['cart'][$id]['quantity']++;
}
else
{
$sql_s="SELECT * FROM products WHERE id_product={$id}";
$query_s=mysqli_query($con,$sql_s);
if(mysqli_num_rows($query_s)!=0)
{
$row_s=mysqli_fetch_array($query_s);
$_SESSION['cart'][$row_s['id_product']]=array
(
"quantity" => 1,
"price" => $row_s['price']
);
}
else
{
$message="This product id it's invalid!";
}
}
}
?>
<h1>Product List</h1>
<?php
if(isset($message)){
echo "<h2>$message</h2>";
}
?>
<table>
<?php
$sql = "SELECT * FROM products ORDER BY name ASC";
$query = mysqli_query($con,$sql);
while ($row=mysqli_fetch_array($query)) {
?>
<tr>
<td><?php echo $row['name'] ?></td>
<td><?php echo $row['description'] ?></td>
<td><?php echo $row['price'] ?>$</td>
<td><a href="index.php?page=products&action=add&id=<?php echo $row['id_product'] ?>">Add to cart</a></td>
</tr>
<?php
}
?>
</table>
), in the JQuery file of the theme that execute on page load and detect the main.js and change the class of Control panel to the Color defined in the <body>.

解决此问题的方法之一是使用 Theme Setting API of Liferay 。
您可以在相应主题的 liferay-look-and-feel.xml 和read this value in vm templates中提供颜色选项，并通过portal_normal.vm
以下几条链接供您参考：

希望这有帮助。
