radio button help

[ianco]

Hi all,

 

I'm haveing trouble with a quiz form i have. The radio buttons aren't selective and somehow i always get the first answer in the list.

 

Can anyone see where i'm going wrong please?

Thanks

 

Ian

 

<FORM NAME ="form1" METHOD ="POST" ACTION ="testy4.php">

<b>Q1.</b>
Je m'appelle?  <br>

<Input type = 'radio' Name ='q1' value ="a" > Ian<br>
<Input type = 'radio' Name ='q1' value ="aa" > Sally<br>

<Input type = 'radio' Name ='q1' value ="aaa" > Keef the fish<br>

<b>Q2.</b>
Voulez vous couche avec moi? <br>

<Input type = 'radio' Name ='q2' value ="b" > Oui<br>
<Input type = 'radio' Name ='q2' value ="bb" > Non<br>
<Input type = 'radio' Name ='q2' value ="bbb" > Je don't know<br>


<INPUT TYPE = "Submit" Name = "Submit1" VALUE = "Submit"><br>

</FORM>

 

<?php



if (isset($_POST['Submit1'])) {
    $cost = array();

/* Q1 */

echo "<b>Q1.<br>

Je m'appelle?

</b><br><br>";


    if (isset($_POST['q1'])) {
        ($_POST['q1'] = "a") ? $cost['q1'] = 'a' : $cost['q1'] = FALSE; echo "Well done, Je m'appelle Ian<br>";
    }
    elseif (isset($_POST['q1'])) {
        ($_POST['q1'] = "aa") ? $cost['q1'] = 'aa' : $cost['q1'] = FALSE; echo "Sally?!?!? You idiot, Je m'appelle Ian<br>";
    }

    elseif (isset($_POST['q1'])) {
        ($_POST['q1'] = "aaa") ? $cost['q1'] = 'aaa' : $cost['q1'] = FALSE; echo "You idiot Keith is a fish! Je m'appelle Ian<br>";
    }
}

if (isset($_POST['Submit1'])) {
    $cost = array();

/* Q2 */

echo "<br><b>Q2.<br>

Voulez vous couche avec moi?

</b><br><br>";

    if (isset($_POST['q2'])) {
    ($_POST['q2'] = 'b') ? $cost['q2'] = 'b' : $cost['q2'] = FALSE; echo "You chose yes. You lucky girl<br>";
    }

    elseif (isset($_POST['q2'])) {
    ($_POST['q2'] = 'bb') ? $cost['q2'] = 'bb' : $cost['q2'] = FALSE; echo "You picked no. Oh dear<br>";
    }

    elseif (isset($_POST['q2'])) {
    ($_POST['q2'] = 'bbb') ? $cost['q2'] = 'bbb' : $cost['q2'] = FALSE; echo "What do you mean you don't know<br>";
    }


}
echo '<br><b>Thanks for doing the quiz</b>';


?>

Okay, for starters. You're HTML is extremely poor, this is how an input should look:

 

<input type="radio" name="q1" value="a" />

 

Now, on to your PHP. To check which answer you selected you need to do something like this:

 

//First you need to check if they selected an answer for Question 1.
if(isset($_POST['q1'])){
//So, they selected an answer. Not to check the value to see what they choose.
if($_POST['q1'] == "a"){
	//They choose A.
	echo "Well done, Je m'appelle Ian<br>";
}elseif($_POST['q1'] == "aa"){
	//The choose AA.
	echo "Sally?!?!? You idiot, Je m'appelle Ian<br>";
}elseif($_POST['q1'] == "aaa"){
	//They choose AAA.
	echo "You idiot Keith is a fish! Je m'appelle Ian<br>";
   }
}else{
//No answer was selected for this question, show an error.
echo "You did not select an answer for Question 1!";
}

 

You need to make sure that you properly check your users submitted form data for errors, as people will sometimes try anything and sometimes that can result in errors. So ensure you have proper validation. I've commented the example code above so that it may help you further.
