Symfony get single form field post value in controller method - php

Question

I'm using symfony 2.8, I'm submitting a registration from to registerAction method. I'm getting all my submitted data like this when I use $form-getdata() in registerAction method.
AppBundle\Entity\User Object
(
[id:AppBundle\Entity\User:private] =>
[name:AppBundle\Entity\User:private] => testname
[email:AppBundle\Entity\User:private] => test#test.com
[roles:AppBundle\Entity\User:private] => Admin User
[plainPassword:AppBundle\Entity\User:private] => 123456
[password:AppBundle\Entity\User:private] =>
)
I have used $request->request->get('name') to get single name value but it is showing blank screen and printing nothing.
My html form looks like this on viewing source code in browser.
<form name="user" method="post" novalidate="novalidate">
<div class="form-group">
<div><label for="user_name" class="required">Name</label><input type="text" id="user_name" name="user[name]" required="required" class="form-control" /></div>
</div>
<div class="form-group">
<div><label for="user_email" class="required">Email</label><input type="email" id="user_email" name="user[email]" required="required" class="form-control" /></div>
</div>
<div class="form-group">
<div><label for="user_roles" class="required">Roles</label><select id="user_roles" name="user[roles]" class="form-control" style="margin:5px 0;"><option value="Normal User">Normal User</option><option value="Admin User">Admin User</option></select></div>
</div>
<div class="form-group">
<div><label for="user_plainPassword_first" class="required">Password</label><input type="password" id="user_plainPassword_first" name="user[plainPassword][first]" required="required" class="form-control" /></div>
</div>
<div class="form-group">
<div><label for="user_plainPassword_second" class="required">Repeat Password</label><input type="password" id="user_plainPassword_second" name="user[plainPassword][second]" required="required" class="form-control" /></div>
</div>
<div><button type="submit" id="user_Register" name="user[Register]" class="btn btn-success form-control">Register</button></div><input type="hidden" id="user__token" name="user[_token]" value="epZFHVctxHFlsnxG-H4OdS92DmGVjP1DDF-bKJrV2Ss" />
</form>
How can I get single posted form value.?

Answer 1

If $request->request->get('{form_name}') returns an array with your form data, then you can access the specific input field with $request->request->get('user')['name']. But you should use form classes instead, where you can define all of necessary fields with validation constraints, etc. Hope this helps!
