Question

In my database I have the following schema:

Answers:

answerId(PK) auto_inc
answer
questionId

I am passing the following JSON String to my php file:

[{"answer":"bnk","questionId":"1"},{"answer":"1","questionId":"2"},{"answer":"b n","questionId":"3"},{"answer":"3","questionId":"4"},{"answer":"rgb","questionId":"5"},{"answer":"No","questionId":"6"},{"answer":"0","questionId":"7"},{"answer":"0","questionId":"8"},{"answer":"0","questionId":"9"},{"answer":"0","questionId":"10"},{"answer":"0","questionId":"11"},{"answer":"0","questionId":"12"},{"answer":"0","questionId":"13"},{"answer":"0","questionId":"14"},{"answer":"3","questionId":"18"},{"answer":"nko","questionId":"19"},{"answer":"hhkl","questionId":"15"},{"answer":"2","questionId":"16"},{"answer":"vnlf hugg","questionId":"17"}]

This is captured via a post request in $_POST[‘answers’]:

if(isset($_POST['submitanswer'])){
  $dbh = connect();
  $user = $_POST['user'];
  $entry = $_POST['entryId'];
  $answers = $_POST['answers'];
  $answers = json_decode($answers); //decode JSON answers

  //for loop to iterate through answers ans insert new row into database
}

How do I iterate through the answers array and insert a new row into my answers table?

Something like:

foreach($answers as $row){
   $query = "INSERT INTO Answers (answer, questionId) VALUES ($row['answer'], $row['questionId'])";
   mysql_query($query);
}

Answer 1

If this code didn’t work for you, try this:

foreach($answers as $row){
 $query = "INSERT INTO Answers (answer, questionId) VALUES (".$row['answer'].", ".$row['questionId'].")";
 mysql_query($query); 
}

Otherwise, I can’t spot anything wrong here.
