Here is the form for user to fill in:

<form action="/process" method="post>
    <div class="donationarea">
                <strong>I would like to adopt:*</strong>
                <fieldset class="form-group">
                    <div class="form-check">
                       <input class="form-check-input" type="radio" name="squaremeter" value="1"> 
                       <label class="form-check-label">
                           1 m2 (€ 2,50)
                       </label>
                    </div>
                    <div class="form-check">
                       <input class="form-check-input" type="radio" name="squaremeter" value="4">
                       <label class="form-check-label">
                           4 m2 (€ 10,-)
                       </label>
                    </div>
                    <div class="form-check">
                       <input class="form-check-input" type="radio" name="squaremeter" value="10">
                       <label class="form-check-label">
                           10 m2 (€ 25,-)
                       </label>
                    </div>
                    <div class="form-check">
                       <input class="form-check-input" type="radio" name="squaremeter" value="20">
                       <label class="form-check-label">
                           20 m2 (€ 50,-)
                       </label>
                    </div>
                    <div class="form-check">
                       <input class="form-check-input" type="radio" name="squaremeter" value="other">
                       <label class="form-check-label">
                          Otherwise, namely (m2): <input type="text" name="squaremeter" placeholder="m2">
                       </label>
                    </div> 
                </fieldset>

            </div> 
</form>

After click submit button, here are the data returned from the form:

We get every post data for the required input field except the first radio button which return empty string. Any hints?

do you put all this html code inside form or outside form?Because i am unable to see any form here? — Death-is-the-real-truth

or maybe the validation rule inside controller makes something strange, please show validation part of your controller. — cssBlaster21895

what purpose this code serve. Otherwise, namely (m2): <input type="text" name="squaremeter" placeholder="m2"> missing the value parameter and may be in testing you are choosing it. — Pawnesh Kumar

In Simple think you need to changes you Otherwise, namely (m2) input text name to name="squaremeter-1" then you will be get value

Array
(
    [squaremeter] => other
    [squaremeter-1] => 
)

It is empty because you have a input text with the same name as radibuttons: squaremeter

Rename the input text to squaremeter-other.
