Barand Posted March 1, 2013 Share Posted March 1, 2013 (edited) Enclose in [ code][ /code] tags or use "<>" button in toolbar You need something like foreach ($quiz_questions as $qid => $q_data) { echo $q_data['question'] . '<br>'; foreach ($q_data['choices'] as $cid => $choice) { echo "$cid - $choice<br>"; } } Edited March 1, 2013 by Barand Quote Link to comment https://forums.phpfreaks.com/topic/275096-writing-a-quiz-help/#findComment-1415882 Share on other sites More sharing options...

Psycho Posted March 1, 2013 Share Posted March 1, 2013 (edited) $output = ''; if(!isset($_POST['choices'])) { //User did not answer the questions, show form $output .= "<form method='post' action=''>\n"; $qNo = 0; foreach($quiz_questions as $qid => $question) { //output the question text $qNo++; $output .= "<p>{$qNo}. {$question['question']}<p>\n"; foreach($question['choices'] as $choiceValue => $choiceText) { $output .= "<input type='radio' name='choices[{$qid}]' value='{$choiceValue}'> {$choiceText}<br>\n"; } } $output .= "<br><br>\n"; $output .= "<button type='submit'>Submit</button>\n"; $output .= "</form>\n";; } Edited March 1, 2013 by Psycho Quote Link to comment https://forums.phpfreaks.com/topic/275096-writing-a-quiz-help/#findComment-1415887 Share on other sites More sharing options...
Barand Posted March 1, 2013 Share Posted March 1, 2013 (edited) like this You will need a couple of hidden fields. One for the answer and another as a dummy radio button in case no selection is made foreach ($quiz_questions as $qid => $q_data) { echo '<strong>' . $q_data['question'] . '</strong><br>'; echo "<input type='hidden' name='answer[$qid]' value='{$q_data['answer']}'>"; echo "<input type='hidden' name='choice[$qid]' value='' />"; //in case no selection foreach ($q_data['choices'] as $cid => $choice) { echo "<input type='radio' name='choice[$qid]' value='$cid' /> $choice<br>"; } } Edited March 1, 2013 by Barand Quote Link to comment https://forums.phpfreaks.com/topic/275096-writing-a-quiz-help/#findComment-1415888 Share on other sites More sharing options...

Jessica Posted March 3, 2013 Share Posted March 3, 2013 What is it supposed to be? Look at your code, you define it later. Why are you trying to use it BEFORE you defined it?
