Questions:
I have quiz application. where questions and answers adding dynamically with add more button. so I have no number of questions and number of answers for each questions. every questions have image, also every answers have image. I want to get every post and files request with foreach loop. I can’t use for loop because I do not know every questions/answers key in array. reason why array key is not known is that maybe user add 5 questions dynamically and then delete 3th and 4th question array keys will be 0,1,4.
in this code problem is undefined offset 1
for ($i=1; $i<count($_POST['questions'])+1 ; $i++) {
echo'<pre>';
echo ($_POST['questions'][$i]['question_en']);
var_dump($_FILES['questions']['tmp_name'][$i]['image_en']);
echo '<br>';
for($j=1;$j<count($_POST['questions'][$i]['answers'])+1;$j++){
echo $_POST['questions'][$i]['answers'][$j]['title_en'];
var_dump($_FILES['questions']['tmp_name'][$i]['answers'][$j]['image_en']);
}
echo '</pre>';
}
How to&Answers:
If the keys of the images are the same of the questions, it might be se solution for you:
foreach( $_POST['questions'] as $question_key => $question ) {
echo'<pre>';
echo ($question['question_en']);
var_dump($_FILES['questions']['tmp_name'][$question_key]['image_en']);
echo '<br>';
foreach( $question['answers'] as $answer_key => $answer ) {
echo $answer['title_en'];
var_dump($_FILES['questions']['tmp_name'][$question_key]['answers'][$answer_key]['image_en']);
}
echo '</pre>';
}
