It doesn't work.
The submit can not find the controller.
I compared the different between 127.0.0.1/user/login and 127.0.0.1 .
This is the login form in the login page:
<form action="/users/login" id="UserLoginForm" method="post" accept-charset
="utf-8">
<div style="display:none;">
<input type="hidden" name="_method" value="POST"/>
<input type="hidden" name="data[_Token][key]" value="
f9da31eb2cd89c4e9c10af7156a36f6bc9ae7fdd" id="Token1312017746"/>
</div>
<div class="input text required">
<label for="UserUsername">Username</label>
<input name="data[User][username]" maxlength="40" type="text" id="
UserUsername"/>
</div>
<div class="input password required">
<label for="UserPassword">Password</label>
<input name="data[User][password]" type="password" id="UserPassword"/>
</div>
<div class="submit">
<input type="submit" value="登录系统"/>
</div>
<div style="display:none;">
<input type="hidden" name="data[_Token][fields]" value="
e44df0d754a25ad586a8cb20d5d0ead3d4e78843%3A" id="TokenFields287192969"/>
<input type="hidden" name="data[_Token][unlocked]" value="" id="
TokenUnlocked1990315235"/>
</div>
</form>
This is the login form element in the homepage
<form action="/users/login" id="displayForm" method="post" accept-charset="
utf-8">
<div style="display:none;">
<input type="hidden" name="_method" value="POST"/>
</div>
<div class="input text">
<label for="username">Username</label>
<input name="data[username]" type="text" id="username"/>
</div>
<div class="input password">
<label for="password">Password</label>
<input name="data[password]" type="password" id="password"/>
</div>
<div class="submit">
<input type="submit" value="login"/>
</div>
</form>
Obviously, The login form in user/login page has been assign some staff
like token, but element is not.
