How to make my scroll bar show under condition

It seems like the issue might be related to the scope of the $flag variable. Currently, you are setting $flag=true inside the if(isset($_POST['bnews'])) block, which means it’s a local variable within that block. To make it accessible outside that block, you should declare it outside the if statement.

Additionally, you are trying to use $flag in the add_scroll_bar function, but it’s not being passed as a parameter. One way to resolve this is to use a global variable or a session variable to store the flag value.

Here’s an example using a session variable:

Set the session variable when the form is submitted:


// Add this line at the beginning of your code

session_start();
// Inside your form submission block

if (isset($_POST['bnews'])) {

$_SESSION['flag'] = true;

// Rest of your code

}

Use the session variable in your add_scroll_bar function:


add_action('astra_main_header_bar_top', 'add_scroll_bar');

function add_scroll_bar()

{

global $wpdb;
$result = $wpdb->get_results("SELECT * FROM wp_breakingnews");

foreach ($result as $row) {
    $ID = $row->ID;
    $bnews = $row->bnews;
}

if (isset($_SESSION['flag']) && $_SESSION['flag'] == true) {
    ?>
    <div class="scroll-container">
        <?php echo '<div class="mouvement">' . $bnews . '</div>'; ?>;
    </div>
    <?php
    $_SESSION['flag'] = false; // Reset the flag
}
// Rest of your code

}

This way, the $_SESSION['flag'] variable will persist across different requests, and you can use it to control the visibility of the scrollbar.
