I've got a lot of radio boxes on a single page within my website.
I know it is possible to submit all of the options as an array that can be directly manipulated by PHP.
<input type="radio" name="SOMETHING_HERE" value="1" />
There are several radio groups and I'd like all of them to submit to one array.
All I'd like to know is the syntax which has to be used in the name="".
Use like this
<input type="radio" name="optionname[]" value="1" />
<input type="radio" name="optionname[]" value="2" />
.
.
You can have your form in either of the following ways.
<input type="radio" name="name[]" value="1" />
<input type="radio" name="name[]" value="2" />
Or
<input type="radio" name="question['question1']" value="1" />
<input type="radio" name="question['question2']" value="2" />
There by you setting the array definition yourself. Hope this answers your query.
$_POST['question'] = array("question1" => 1, "question2" => 2)?HTML looks like this:
<input type="radio" name="name[]" value="1" />
<input type="radio" name="name[]" value="2" />
PHP accesses it like this:
<?php
$_POST['name'] = array('1','2');
Some things to note:
$_POST['answers'] = array("QuestionId" => Answer);?
value="foo" name="answers[QuestionId]" you would get $_POST['answers'] = array("QuestionId" => "foo");, but remember you must be careful to keep QuestionId unique for every input node.
