<input type="checkbox" id="one" name="form[age[]]" value="1"/><label for="one">0 to 12 months</label>
How do I reference the name in PHP once it has been submitted using POST. I am trying to collect all the checkbox values and then implode age[], but I need to put this in a form[] for form validation.
When i print_r[$_POST['form']['age'], it displays Notice: Undefined index: age
Simply use the key form and the key age in form:
$age = $_POST['form']['age'];
$imploded = implode(',', $age);
The value of the HTML-Attribute name is the key in $_POST, so form is $_POST['form']
Edit: The syntax of your name value is wrong, use form[age][] instead.
You should use name="form[age][]" for every checkbox with age value, and then after you send those values to PHP they will be available as an array $_POST['form']['age'].
Example:
<input type="checkbox" name="form[age][]" value="1"/>
<input type="checkbox" name="form[age][]" value="2"/>
<input type="checkbox" name="form[age][]" value="3"/>
will result an array in PHP like:
$_POST['form']['age'][0]; // = 1
$_POST['form']['age'][1]; // = 2
$_POST['form']['age'][2]; // = 3
I think you want this:
<input type="checkbox" id="one" name="form[age][]" value="1"/>
<input type="checkbox" id="one" name="form[age][]" value="2"/>
.
.
<input type="checkbox" id="one" name="form[age][]" value="12"/>
<?
$implode = implode(',', $_POST['form']['age']);
?>
