如何在链接和选择中正确编码ID

Question

(Working with CodeIgniter)

Hi there, thanks for reading me.

Quick question that I always stumble on while being in development...

How can I encode properly the IDs of the elements I'm showing on webpages... I want, on select change to show something else with Ajax in my main controller but I think that having the direct ID ( of the scope here ) staying there in my html is kind of wrong... Or am I wrong ?

For exemple, on selection a scope in here, I would load that scope, based on its ID, and show different information about it in the remaining of the page.

[HTML]

<select>
    <?php
    foreach ($scopes as $scope)
    {
    ?>
        <option value="<?=$scope->get_ScopeID();?>"><?=$scope->get_Name();?></option>
    <?php
    }
    ?>
</select>

I've played a little bit with ajax, a good while with JQuery, no matter what website I look on, I can't seem to find the ID of the item I'm clicking on, so I concluded that I'm doing something wrong !

Thank you !

Exposing database items' IDs to the client is absolutely fine, and you're doing it right.

Take a look at this question's URL for example. 21561011 is the ID of the question in the database, and it's exposed to the client.
