Function Problem

[Phplearner123]

if(isset($_REQUEST['flag']) == "yes")
{

$loginData->Check_Login(trim($REQUEST['authen_username']),trim($REQUEST['authen_password']));

}

<td align="left">Username</td>
<tr>
<td align="left"><input class="field" id="authen_username" name="authen_username" id="authen_username" tabindex="1" type="text" size="35"/></td>
</tr>
<tr>
<td align="left">Password</td>
</tr>
<tr>
<td align="left">
<input class="field" name="authen_password" id="authen_password" tabindex="2" type="password" size="35" />
<input type="hidden" value="yes" name="flag"></td>

The check login function is not working means the value of $_REQUEST['flag']) is null.what is the problem in this code..As i am new to this PHP i dont know what is the problem.It is the login form.Please help me.How can i set the flag value to yes.

firstly

if(isset($_REQUEST['flag']) == "yes")

...doesn't really make any sense. I think it should probably read

if(isset($_REQUEST['flag']) && $_REQUEST['flag'] == "yes")
