Keep button disabled till the current page reloads (using Jquery)

I have a search bar in index.php and when I type an ID, the SQL data is fetched from fetch.php. The fetch.php contains “AddToZip” button for each row of SQL data. When I click on a selected button, the selected button is disabled (going properly till here). But when I clear the search bar to write a different ID or perhaps same ID, all the disabled buttons of “AddToZip” are reactivated/enabled. How do I keep them disabled when the user uses the search bar multiple times and they anyhow get enabled only when the user refreshes the page.

index.php

<php code>

<?php
session_start();
...

Answer

Can you add the code of AddToZip.php ?

You could store all ids into a session value, and check if the id is containt inside this array on your fetch.php.

AddToZip.php :

session_start();
if (!isset($_SESSION['added_to_zip_ids']))
    $_SESSION['added_to_zip_ids'] = [];
if (array_search($_GET['id'], $_SESSION['added_to_zip_ids']) === false)
    $_SESSION['added_to_zip_ids'][] = $_GET['id'];

fetch.php :

<?php
...

session_start();
if (!isset($_SESSION['added_to_zip_ids']))
    $_SESSION['added_to_zip_ids'] = [];

if(mysqli_num_rows($result) > 0)
{
 $output .= '<h4 align = "center">Search Result</h4>';
 $output .= '<div class="table-responsive">
                <table class = "table table bordered">
                   <tr>
                        <th>ID</th>                                 
                    </tr>';
                    
    while($row = mysqli_fetch_array($result))
    {
                
        $output .= '
                <tr>
                    <td>'.$row["ID"].'</td>
                    <td><button '.(array_search($row["ID"], $_SESSION['added_to_zip_ids']) === false ? '' : 'disabled').' type="button" class="btn btn-primary" onclick="addToZip(''.$row["ID"].'', this)"><i class="fa fa-pdf" aria-hidden="true"> </i>Add to Zip</button></td>
                </tr>
            ';
    }
    echo $output;
    
}
...

?>

And to clear the stored values, you have two solutions :

Keep other session datas

session_start();
if (isset($_SESSION[‘added_to_zip_ids’]))
unset($_SESSION[‘added_to_zip_ids’]);
Clear everything

session_start();
session_unset();

These line can be anywhere on the server.
