无论如何使用PHP在服务器端单击一次后永久禁用引导按钮?

I'm trying to disable a bootstrap button permanently after one click. I know how to do this on client side using JavaScript but after refreshing page, it becomes enabled. So, I want to do it on the server side. But don't know how to do it. Can anyone help??

    There would need to be informed in a database in order for the button to know if it needs to be pressed.

    I would suggest either using an Ajax request to do an insert statement into a database once the selected button is pressed or you can use it through a tag submits into an insert statement in order to get the data to see if it should be permanently selected.

    Then you would need a select statement to read the database data into an IF statement such as this;

    ($row['Button_Pressed'] == '1' ? 'Selected' : '')
    

    The Button_Pressed is just the column in the table that would store the data and the 1 is the boolean value

    This solution worked for me to disable a bootstrap button:

    <?php
        $a=1;
        echo ($a==1) ? '<a href="update.php" class="btn btn-success btn-lg">Mark complete</a>' : '<a href="lect_pro_updater.php" class="btn btn-success btn-lg disabled">You completed this</a>';
    ?>
    

    It will keep button active if the condition is true else create a new disabled button.

    If you don't want to use a ternary operator then use if and else statements like:

    if($a==1){
    '<a href="update.php" class="btn btn-success btn-lg">Mark complete</a>'
    }
    
    else{
    '<a href="update.php" class="btn btn-success btn-lg disabled">Mark complete</a>'
    }
