How to place two forms on the same page? - php

Question

I want to place both register and login form on the same page.
They both starts with:
if (!empty($_POST)) ...
so, I need something like:
if (!empty($_POST_01))... // regForm
and
if (!empty($_POST_02))... //loginForm
Also how to prevent executing first form if the second is busy, and vice versa (user clicks on both)
My idea is to create a simple variable on starting process, for example $x = 1 and at the end of process $x = 0, so:
if ((!empty($_POST_01)) And $x = 0)...
Probably, there is a better way.

Answer 1

You could make two forms with 2 different actions
<form action="login.php" method="post">
<input type="text" name="user">
<input type="password" name="password">
<input type="submit" value="Login">
</form>
<br />
<form action="register.php" method="post">
<input type="text" name="user">
<input type="password" name="password">
<input type="submit" value="Register">
</form>
Or do this
<form action="doStuff.php" method="post">
<input type="text" name="user">
<input type="password" name="password">
<input type="hidden" name="action" value="login">
<input type="submit" value="Login">
</form>
<br />
<form action="doStuff.php" method="post">
<input type="text" name="user">
<input type="password" name="password">
<input type="hidden" name="action" value="register">
<input type="submit" value="Register">
</form>
Then you PHP file would work as a switch($_POST['action']) ... furthermore, they can't click on both links at the same time or make a simultaneous request, each submit is a separate request.
Your PHP would then go on with the switch logic or have different php files doing a login procedure then a registration procedure

Answer 2

Well you can have each form go to to a different page. (which is preferable)
Or have a different value for the a certain input and base posts on that:
switch($_POST['submit']) {
case 'login':
//...
break;
case 'register':
//...
break;
}

Answer 3

Give the submit buttons for both forms different names and use PHP to check which button has submitted data.
Form one button - btn1
Form two button -btn2
PHP Code:
if($_POST['btn1']){
//Login
}elseif($_POST['btn2']){
//Register
}

Answer 4

You can use this easiest method.
<form action="validator.php" method="post" id="form1">
<input type="text" name="user">
<input type="password" name="password">
<input type="submit" value="submit" form="form1">
</form>
<br />
<form action="validator.php" method="post" id="form2">
<input type="text" name="user">
<input type="password" name="password">
<input type="submit" value="submit" form="form2">
</form>

Answer 5

Here are two form with two submit button:
<form method="post" action="page.php">
<input type="submit" name="btnPostMe1" value="Confirm"/>
</form>
<form method="post" action="page.php">
<input type="submit" name="btnPostMe2" value="Confirm"/>
</form>
And here is your PHP code:
if (isset($_POST['btnPostMe1'])) { //your code 1 }
if (isset($_POST['btnPostMe2'])) { //your code 2 }

Answer 6

Hope this will help you. Assumed that login form has: username and password inputs.
if(isset($_POST['username']) && trim($_POST['username']) != "" && isset($_POST['password']) && trim($_POST['password']) != ""){
//login
} else {
//register
}
