我正在尝试使用$ _GET更改CSS属性以获得错误的结果

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") { 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

This is because the second parameter sel passed in the URL should be directly appended to the first argument declared with the ampersand ( & ) identifier.

The use of the fragment identifier ( # ) in the middle of your arguments is misleading as he can also be used to declare arguments to the URL. If the hash mark is meant to identify an anchor, it is better to place it at the end for avoiding errors and better readability :

http://you-url.com/?page_id=98&sel=q1s#highlights

Answer 2

Try something

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

and see what is in the $_GET
