While Function

Hey,

Im kinda confused about something im having a problem with. I am am in the process of making a quiz script. Located @ http://www.topshotter.com/quiz to see what i mean

The code below will explain in more detail. I am trying to get the script to detect if any of the forms are blank. I know how to but it all depends on how many questions someone has requested to setup.

<?php

if ($n == $null) {
echo "halt";
exit;
}

#echo "$answer1_1 $answer1_2 $answer1_3";

$i=1;
while ($i <= $n):

if ($answer$i_$i == $null) {
echo "Required Fields are missing. \n";
echo "Answer #$i is blank, ";
}

$i++;
endwhile;

the problem I am having is well it wont work. Don't mind the code its in "Debug" mode lol. I hope this is understandable to you. Hope to get some help with this.

Thanks a bunch!

try this

if (${answer.$i.'_'.$i} == $null) { 
echo "Required Fields are missing.<br></br>\n"; 
echo "Answer #$i is blank, "; 
}

or...

if (${'answer' . $i . '_' . $i} == $null)
{ 
    echo "Required Fields are missing.<br></br>\n"; 
    echo "Answer #$i is blank, "; 
}

and do you need a colon after the while condition?

And, besides, I believe that "$null" is reallly 0 or "". 🙂
