symfony request returns only one request - twig

Question

i am working with symfony 3 and twig. I take DNS info from a API. But i can never know how many rows it will be. So here is the problem lets say domain www.example.com has 3 DNS's when i request get form my controller i only get the last DNS back from the form.
twig:
{% if dnsinfo is defined %}
<form class="form-inline" method="post" action="/setdns">
{% if dnsinfo is not empty %}
{% for dns in dnsinfo %}
<div class="row " >
<div class="input-group col-xs-3">
<input type="text" id="dns" name="dns" value="{{ dns.1 }}" class="form-control">
</div>
<div class="col-xs-2 input-group">
<select class="form-control" id="type" name="type" style="width:100%;">
<option value="notselected" selected disabled>* Select a type</option>
<option value="A"{% if dns.2 == 'A' %} selected{% endif %}>A</option>
<option value="AAAA"{% if dns.2 == 'AAAA' %} selected{% endif %}>AAAA</option>
<option value="CNAME"{% if dns.2 == 'CNAME' %} selected{% endif %}>CNAME</option>
<option value="MX"{% if dns.2 == 'MX' %} selected{% endif %}>MX</option>
<option value="SOA"{% if dns.2 == 'SOA' %} selected{% endif %}>SOA</option>
<option value="TXT"{% if dns.2 == 'TXT' %} selected{% endif %}>TXT</option>
<option value="SRV"{% if dns.2 == 'SRV' %} selected{% endif %}>SRV</option>
</select>
</div>
<div class="col-xs-3">
<input type="text" id="content" name="content" value="{{ dns.3 }}" class="form-control">
</div>
<div class="col-xs-1">
<input type="text" id="ttl" name="ttl" value="{{ dns.4 }}" class="form-control">
</div>
<div class="col-xs-3">
<input type="text" id="prio" name="prio" value="{{ dns.5 }}" class="form-control">
</div>
</div>
<hr class="divider" style="">
{% endfor %}
{% endif %}
<input type="submit" class="btn btn-success" value="Save">
Cancel
</form>
{% endif %}
symfony controller:
$this->pre($request->request->get('dns'));
$API = $this->connect();
$dns = array(
'domain' => $request->request->get('domain'),
'extension' => $request->request->get('ext'),
'dnsdata' => serialize( array(
1 => array(
'name' => $request->request->get('dns'),
'type' => $request->request->get('type'),
'content' => $request->request->get('content'),
'ttl' => $request->request->get('ttl'),
'prio' => $request->request->get('prio')
)
))
);
$API->prepare('dns', $dns);
Of course i know a solution. Working with numbers behind the fields name1 name2 etc. But there must be a better way to do this right? What i am trying to get is if i print my request:
[dns] => array (array with all the DNS's i send in my form)
this is what is inside form data
https://gyazo.com/ebd558ba7f1ef8e1bfbe86e115bbb1e
as you can see it hold all the data i need yet with $request->request->get() i can only take the last one.
So my question is how to get all the data out?
vardump and the form that returns all the fields https://gyazo.com/0b9725ba8e298c6f59f343d3d5a548c7
sollution:
I ended up working with numbers so i can know how many fields are send from the api. And then looping to all of the fields
{% if dnsinfo is defined %}
{% set i=0 %}
<form class="form-inline" method="post" id="form" action="/setdns">
<input value="{{ domain }}" hidden name="domain" id="domain">
<input value="{{ ext }}" hidden name="ext" id="ext">
{% if dnsinfo is not empty %}
{% for dns in dnsinfo %}
<div class="row " >
<div class="input-group col-xs-3">
<input type="text" id="dns{{ i }}" name="dns{{ i }}" value="{{ dns.1 }}" class="form-control">
</div>
<div class="col-xs-2 input-group">
<select class="form-control" id="type{{ i }}" name="type{{ i }}" style="width:100%;">
<option value="notselected" selected disabled>* Select a type</option>
<option value="A"{% if dns.2 == 'A' %} selected{% endif %}>A</option>
<option value="AAAA"{% if dns.2 == 'AAAA' %} selected{% endif %}>AAAA</option>
<option value="CNAME"{% if dns.2 == 'CNAME' %} selected{% endif %}>CNAME</option>
<option value="MX"{% if dns.2 == 'MX' %} selected{% endif %}>MX</option>
<option value="SOA"{% if dns.2 == 'SOA' %} selected{% endif %}>SOA</option>
<option value="TXT"{% if dns.2 == 'TXT' %} selected{% endif %}>TXT</option>
<option value="SRV"{% if dns.2 == 'SRV' %} selected{% endif %}>SRV</option>
</select>
</div>
<div class="col-xs-3">
<input type="text" id="content{{ i }}" name="content{{ i }}" value="{{ dns.3 }}" class="form-control">
</div>
<div class="col-xs-1">
<input type="text" id="ttl{{ i }}" name="ttl{{ i }}" value="{{ dns.4 }}" class="form-control">
</div>
<div class="col-xs-3">
<input type="text" id="prio{{ i }}" name="prio{{ i }}" value="{{ dns.5 }}" class="form-control">
</div>
</div>
<hr class="divider" style="">
{% set i = i + 1 %}
{% endfor %}
{% endif %}
<input type="submit" class="btn btn-success" onclick="$('#form').attr('action','/setdns{{ i }}')" value="Save">
Cancel
</form>
{% endif %}
as you can see in my button i use jquery to send the number to my controller
/**
* #Route("/setdns{i}", name="setdns", requirements={"i": "\d+"})
*/
public function setdns(Request $request, $i = false) {
$API = new Whoisdomainmodify();
$API = $API->connect();
for ($x=0; $x < $i; $x++) {
$dns = array(
'domain' => $request->request->get('domain'),
'extension' => $request->request->get('ext'),
'dnsdata' => serialize(array(
1 => array(
'name' => $request->request->get('dns'.$x),
'type' => $request->request->get('type'.$x),
'content' => $request->request->get('content'.$x),
'ttl' => $request->request->get('ttl'.$x),
'prio' => $request->request->get('prio'.$x)
)
))
);
echo '<pre>';
print_r($dns);
$API->prepare('dns', $dns);
// $API->execute();
// $API->fetch();
}
$this->addFlash('Success', 'DNS successfully changed');
return $this->redirectToRoute('registereddomain');
}
if there is a better way to do this please tell me. Because i send all my form data see gyazo.

Did you know that the for loop in Twig has variables:
http://twig.sensiolabs.org/doc/tags/for.html#the-loop-variable
for example you could use:
{{ dns.loop.index0 }}
or something along those lines. Try it out. Twig is very powerful, if you get familiar with it, it might save you a lot of coding. I'm not sure if this is an answer, but it might help you out.
