Merging two login forms

[legionarius]

I'll try to keep this simple, I need to make so that when someone logs in using the PRIMARY FORM they are also automatically logged into a SUB FORM using the same username and pass that they entered in the primary form. I hope this makes sense:

PRIMARY FORM

<form action="http://primary...link.com/login.php" method="post" onSubmit="return disablePage();" class="formLayer"><fieldset><legend>Login</legend><br><label>Your Email Address:</label><input type="text" name="email" value="" size="50"><br><label>Password:</label><input type="password" name="password" value="" size="25"><br><br><label></label><input type="submit" name="submitBtn" value="Login" class="btn" onmouseover="this.className='btnhov'" onmouseout="this.className='btn'"> <input type="reset" name="resetBtn" value="Reset" class="btn" onmouseover="this.className='btnhov'" onmouseout="this.className='btn'"><br><br><input type="hidden" name="url" value="/"></fieldset></form>

---

SUB FORM

<form action="http://site2...link.com/login.php" method="post">
			<input type="hidden" name="action" value="login" />
			<table class="no-backgrounds vtop tbullet" cellpadding="0" cellspacing="0">
				<tr>
					<th style="width:100px;"><label>Email</label></th>
					<td><div class="holder"><div class="fixedtooltip"><p>Please enter your email address.<br />This field is required.</p></div></div>
						<input type="text" value="" name="email" /></td>
				</tr>
				<tr>
					<th style="width:100px;"><label>Password</label></th>
					<td><div class="holder"><div class="fixedtooltip"><p>Please enter your login password.<br />This field is required.</p></div></div>
						<input type="password" name="password" value="" /></td>
				</tr>
				<tr>
					<th class="nobullet">&nbsp;</th>
					<td><input class="fleft" type="image" src="/img/buttons/login.png" /></td>
				</tr>
			</table>
		</form>

When posting HTML code, please use the board's [noparse]

..

[/noparse] bbcode tags as they make your code easier to read and analyze.

As for your issue, is the second form on the same server as the one that the user is submitting? If not, I'm not sure what you're asking.... you can simulate a POST request to the second form using cURL or something similar, but normally "logging in" will set a cookie or something similar.

No, the second form is on another server. how do i use cURL?

User logs in using primary form -> simutaltes post request to second form -> user now longer has to login to two members areas.

How does the other server authenticate users once they've logged in? If it's by a cookie, then you're out of luck, since you can't set cookies on behalf of other domains.
