如何 - 显示 属性 上的 If 语句

How to - If statement on Display Property

这会显示公司徽标

{display property='Logo' object_sid=$user_sid}

但是,如果不显示某些内容,我怎么知道他们是否有徽标显示它。

感谢您的帮助。

if-else 语句首先检查给定条件,如果满足则移至第一部分或 else 移至另一部分。

一个例子:

<?php
    $display_property = "Logo";
if(isset($display_property)){
    echo $display_property;
}else
{
    echo "No display";
}
?>

Note: Given with the Information in your question, this example was created. However this might not do the EXACT thing but would play a vital role in understanding what you're struggling with.
