Checkbox And Radio Buttons

[Anon]

Hello,

What I am asking is I have a form that has questions using checkbox and radio buttons, and when they submit, it checks the form and re-prints it if errors with the values they entered. I was wondering how I can have the values they entered using checkboxes and radio buttons appear as they entered them? So the checkbox they checked will still be check etc.

Thankyou.

Hello! The way that you specifiy in HTML which radio button is selected, or if a checkbox is checked is with a "SELECTED" command in the input tag, so I tend to us a function like this:

radio buttons:
function isselected($checkValue, $trueValue) {
$tagPrint = "VALUE=$checkValue";
if($checkValue == $trueValue)
$tagPrint .= " SELECTED";
return $tagPrint;
}

<INPUT TYPE=radio NAME=radioName <?isselected(radio1,$radioName);?> >
<INPUT TYPE=radio NAME=radioName <?isselected(radio2,$radioName);?> >
etc.

For CheckBoxes:
<INPUT TYPE=checkbox NAME=checkName <?if (isset($checkName)) print "SELECTED";?>>

PS- Make sure that if you are redirecting back to this page that you ensure that $checkName and $radioName get passed back to it (with cookies or session vars or whatever you choose to do)
