Get inputs, concatenate them, and define as PHP variable without reloading?

[Repgahroll]

Hello there.

 

I'm learning Joomla, and the following lines works well to store "myvar" on database.

 

<input type="text" name="myvar" value="<?php echo $myvar ?>"/>
<?php $this->user->myvar = $myvar; ?>

 

However, i want to store more than one input, so i wonder if it's possible to do something using javascript.

 

For example

 

<input type="text" name="myvara" value=""/>
<input type="text" name="myvarb" value=""/>

--some way to concatenate "on the fly" myvara+","+myvarb into myvar--

--some way to make it readable for php as "myvar" on input name above--

<?php $this->user->myvar = $myvar; ?>

 

Thanks in advance.
