我正在尝试使用$ _GET更改css属性但是没有得到结果

Question

First of all this is a wordpress page so [insert_php] is a replacement for <?php.

The url of the page is as follows "http://**.com/?page_id=98#highlights?sel=q1s"

the code on the page is as follows

<div id="Question1" style="background-color:[insert_php] if ($_GET['sel'] == "q1s") { return "black"; } else { return "white"; };">

I'm sure I'm overlooking something here.

EDIT :

<div id="Question1" style="background-color:[insert_php] if ($_GET['sel'] == "q1s") { echo "black"; } else { echo "white"; }[/insert_php];">

this is my current code and it still showing no results, I checked the actual value I'm getting for background-color and for some reason am getting the result "white".

Answer 1

I'm not sure but I think the parenthesis is missing around the condition, and also you have to use an echo; like this :

if ($_GET['sel'] == "q1s") { echo "black"; }
