Okay so I have a script which is basically like an order form. However my only input options are radio buttons. When I run my script, I noticed that it turned back errors. Instead I would like it to display and empty field. The page posts back to itself and it updates a box I left blank on the bottom before submission. After submission details are filled in from a multitude. I also used a two dimensional array if that makes any difference. So my problems are with empty variables in the forms. I was not able to fix this and I think it might be the way I'm using it. I get an undefined index error for the variables that receive the data. In this case $settype and $differentype come out as errors since they are defined to be whatever was in the textbox. I thought that by using empty() I could eliminate that issue. I did not approach it correctly of course. Can anyone give me some guidance here? Thank you.
<form name="form1" method="POST" action="order.php">
<input type="radio" name="set" value="1" /> 1
<input type="radio" name="set" value="2" /> 2
<input type="radio" name="set" value="3" /> 3
<input type="radio" name="different" value="a" /> a
<input type="radio" name="different" value="b" />
<input type="radio" name="different" value="c" />
<input type="submit" name="submit1" value="login" />
</form>
<?php
if(isset($_POST['submit'])) {
$settype = $_POST['set'];
$differentype = $_POST['different'];
if ($settype == '1' && $differenttype =='a'){
$order = $field[0][1];
}
if (empty($settype) && empty($differenttype)){
$order = "";
}
}
?>
<table>
<tr>
<td>
<?php print($order); ?>
</td>
</tr>
</table>
Where is your input submit ? like this <input type="submit" name="submit" value="submit" />
EDIT 1: You should have a default radio button selected value like
<input type="radio" name="set" value="1" checked="checked"/> 1
<input type="radio" name="different" value="a" checked="checked" /> a
