[quote author="InsiteFX" date="1407588668"]It's Controller/Method.

Code:

<form action='../welcome/doTest' method="post">

// should be
<form action='welcome/doTest' method="post">

[/quote]

I try to use

Code:

<form action='welcome/doTest' method="post">

But URL what i get is http://mydomain.com/welcome/welcome/doTest

Actually, I tested

Code:

<form action='<?=base_url('welcome/doTest');?> method="post">
or <form action='doTest' method="post">

It will send to http://mydomain.com/welcome/doTest

It's work if I use normal text like: aaa, text
But if input protocol name like http://, ftp:// It's not work.
