Question

I have a form:

<form name="form1" method="post" action="form_to_write.php">
    <h4>q1</h4>
    <input type="radio" name="a1" value="someValue1" />someValue1<br />
    <input type="radio" name="a1" value="someValue2" />someValue2<br />
    <input type="radio" name="a1" value="someValue3" />someValue3
    <h4>q2</h4>
    <input type="radio" name="a2" value="someValue4" />someValue4<br />
    <input type="radio" name="a2" value="someValue5" />someValue5<br />
    <input type="radio" name="a2" value="someValue6" />someValue6
    <h4>q3</h4>
    <input type="radio" name="a3" value="someValue9" />someValue9<br />
    <input type="radio" name="a3" value="someValue7" />someValue7<br />
    <input type="radio" name="a3" value="someValue8" />someValue8
    <input type="submit" value="submit" name="submit"/>
</form>

And want to read all inputs to array by type (radio). I know, how to read it by name, but how by type?

Answer 1

make your form_to_write.php like this:

<?php
print_r($_POST);

and study it’s output.
It contains everything you can get from the form. You are free to choose what to use. Enjoy.

As your question being a perfect example of a badly asked question, I can only guess your real needs.

It seems you want to get an array contains all radio buttons. You still can do it by using names.

make your radio buttons names like this

<input type="radio" name="radios[a1]" value="someValue1" />someValue1<br />

<input type="radio" name="radios[a2]" value="someValue4" />someValue4<br />

<input type="radio" name="radios[a3]" value="someValue9" />someValue9<br />

and you’ll be able to access $_POST['radios'] array which contains all your radio fields
