Firstly, I'd get rid of the single quotes at they come out as
Age'1', but you probably want Age1
For an unknown number of ages you could do:
$ages=array();
foreach( $POST as $key=>$value ) {
if (substr($key,0,3)=="Age") {
$ages[$key]=$_POST[$key];
}
}
If there were 5 ages you would end up with
$ages["Age1"] = <age_entered1>;
$ages["Age2"] = <age_entered2>;
$ages["Age3"] = <age_entered3>;
$ages["Age4"] = <age_entered4>;
$ages["Age5"] = <age_entered4>;
If you don't want an array, you can do:
foreach( $POST as $key=>$value ) {
if (substr($key,0,3)=="Age") {
${$key}=$_POST[$key];
}
}
The ${$key} would make your variables $Age1, $Age2 etc.
Hope that helps, untested, let me know.
