Radiobutton function

[daantje79]

I'm trying to build a function which will return a number of radio buttons with different values to insert into a DB-field.

That not a problem..

The problem is when updating that field i want the chosen fieldvalue to be checked.

I came up with this:

$name = the fieldname
$options = the values for the buttons seperated by "|"
$db_value = the value of the DB-field

function inputRadio($name, $options, $db_value) {
$option=explode ("|", $options);
array_walk ($option, 'walk', $db_value);
}
function walk($item, $put, $db_value){
if ($db_value==$item){
$d = "c";
}
else {
$d = "";
}
for ($k=0; $k<count($d); $k++) {
$radio = " <input $d[$k]hecked type=radio name=$name value=$item>&nbsp;$item&nbsp;&nbsp";
}

			return $radio;

}

I have to have the results returned (not echo) otherwise it wont work with my layout function

I'm going mad please help

Kind Regards

Daniel

function inputRadio($key, $options, $db_value) {
$option=explode ("|", $options);
for ($k=0; $k<count($option); $k++) {
$radio.= " <input" .($db_value==$option[$k] ? " checked" : "") . " type=radio name=$key value=$option[$k]>&nbsp;$option[$k]&nbsp;&nbsp";
}
return $radio;
}

Have you tried using the built in "CHECKED" attribute? For example, here's a snippet of code that I use for radio buttons (sorry for the formatting) :

if ($default == 1)
{
echo "<INPUT TYPE = \"radio\" NAME = \"AppendNum\" VALUE = \"1\" CHECKED>Do something. <br>";

echo "<INPUT TYPE = \"radio\" NAME = \"AppendNum\" VALUE = \"0\">No, do not do something.<br>";
}

else
{
echo "<INPUT TYPE = \"radio\" NAME = \"AppendNum\" VALUE = \"1\">Do something. <br>";
echo "<INPUT TYPE = \"radio\" NAME = \"AppendNum\" VALUE = \"0\" CHECKED>No, do not do something.<br>";
}

Basically what this does, using the conditional operator (?) is to select the value of $default. IOW, if $default contains a 1, then that radio button will be checked. Otherwise, the other button will be checked.

I hope this is on track to what you are looking for. Note: this scheme can also be used for default selections in list boxes.
