I have a table and it contains more than one column, and one of columns is to check/select all checkboxes in my table rows, actually I can select one or multiple checkboxes if I want from the checkboxes that are in the rows.
I have searched and found this result: multiple checkboxes with php in table but it's not helpful, and I couldn't understand it completely.
What I want from my code to do is: When I select one or multiple checkboxes, then when I click on (Publish) button -the code for the button is down below within the page code- the page should receive the selected values from the checkboxes and send them to the same page (article?do=pub&articleid='.$fileid)
This is the code:
<?php 
    $Title = 'Manage Approved Articles';
    include 'init.php';
    $AdminName = $_SESSION['username'];
    // Check if user is the Admin or not
    $stmt = $con->prepare('SELECT Username FROM users WHERE Username = ? AND isAdmin = 1');
    $stmt->execute(array($AdminName));
    $count = $stmt->rowCount();
    if($count > 0) { }  else {
        header('Location: ../index');
        exit();
    }
    ?>
        <section class="Cust-container">
    <?php
      $do = isset($_GET['do']) ? $_GET['do'] : 'article';
      if($do == 'article') { echo 
      '<h2 class="heading">Manage Articles</h2>'; ?>
      <!-- Manage Articles Page -->
        <table class="admin-article-table">
            <thead>
                <tr>

Table for checking multiple checkboxes
I am a beginner and I don't know a lot about php and handling requests (get and post). if I didn't clarify my question enough please ask me in which point I didn't, so you can fully understand my problem and help me solving it hopefully.
So much of thanks.
