filtering emails during registration possible?

[Shadman]

Hi, I am trying to limit the people who will use my classified based on email address.

Here is the logic behind the code. I want to know if this is feasible and how difficult it will be to implement.

I like to input an evaluation code on the registration page of my template.

It will only evaluate emails. It will compare the email that the user input with an external database (which I connect to via API) to see if there is an exact match. If it is then then they can complete their registration and have an account. If not they will get an error page.

Here is the email input portion of the code as it stands by default.

<tr>
<td class="formleft"><span class='required'>{$smarty.const.LANG_STAR}</span>{$smarty.const.LANG_USER_EMAIL_CONFIRM}{$smarty.const.LANG_COLON}<br /><span class="small">{$smarty.const.LANG_USER_MUST_MATCH}</span></td>
<td class="formright"><input name="emailconfirm" type="text" id="emailconfirm" value="{$emailconfirm}" size="{$smarty.const.FIELD_SIZE}" /></td>
</tr>

I need help with the php and building this evaluator. How would I do this? is there a sample code I can look at and mimic? I am a php newbie.

Thanks

I would have to recommend contacting them and seeing if they have any examples. The login.php file handles the original posted email then you will need to take that and integrate with their API. Sorry can't help to much because every system is different.

Thanks for replying.

I have an question, can this be done with a PHP Comparison Operators? without messing with the login.php?

Your question doesnt make sense and without knowing more about the API your going to use no one can offer any substantial help.

Whats likely to happen is you have to pass along the e-mail address of someone who is registering to a emote script and it in turn will say yes or no and you in turn continue based on that. So yes, in a sense there will be comparison operators but we cant really give you an example because we have no idea what you are using.

php.net has all sorts of examples of comparison operators. But if you wantspecific answers you have to provide specific details.
