PHP $_GET is not getting any value

Question

I am trying to make this code works, but I always received a NULL value from $_GET["page"]

<div class="menu">
       
        <ul class="admin-menu">
        
            <?php if (isset($_GET["page"])) : ?>
            
                <?php if ($_GET["page"] == "opt1") : ?>
                    <li class="menu-item">
                       <a class="item-link" href="option1" name="opt1">Altas</a>
                    </li>
                    <br>
                <?php endif ?>

                <?php if ($_GET["page"] == "opt2") : ?>
                    <li class="menu-item">
                        <a class="item-link" href="baja" name="baja">Bajas</a>
                    </li>
                    <br>
                <?php endif ?>

            <?php endif ?>

        </ul>

    </div>

    <!-- Working area -->
<div class="working">

    <?php
            if (isset($_GET["page"])) {
                
                if (
                    $_GET["page"] == "opt1"   ||
                    $_GET["page"] == "opt2"
                ) {
                    include "admin/admin.".$_GET["page"].".php";              
                }
            } else {
                include "view/pages/system/error404.php";
            }
        ?>

</div>

and this is my .htaccess file

Options All -Indexes

RewriteEngine on
RewriteRule ^([-a-zA-Z0-9/]+)$ index.php?page=$1

I really don't know what to do, I saw a lot of examples on line but not luck

Does it work when you enter something like index.php?page=opt1? — Progrock

You do not seem to have any <form> tags. Also, I don't think an <a> element works as a form element. You also don't have any elements with the name attribute set to page. Also, the code in your <div class="working"> block looks like it has syntax errors. Also, you your HTML is invalid, you never end the first <div class="menu"> element. — GrumpyCrouton

@Progrock I tried and the answer is NO, it took me to the index.php — dgoldfeder

Finally I saw my error, I used index.php?page=opt1 instead of master.php that is the one who control the system. — dgoldfeder

you have a syntax error replace

if (
      $_GET["page"] == "opt1"   ||
      $_GET["page"] == "opt2"   ||"
) {

with

if (
      $_GET["page"] == "opt1"   ||
      $_GET["page"] == "opt2"  
) {

or if(in_array($_GET["page"], ['opt1', 'opt2'])) ;p

also it is not clear what you are trying to do with <a class="item-link active" href="option1" name="opt1">Altas</a> but is probably not what you want, as the name attribute doesn't serve any purpose in a <a> tag

Sorry for that, I delete other options i have in the code trying to reduce it, and forgot to delete the OR
