Submit multiple forms that are created in PHP while loop with one button

Question

I am attempting to submit multiple values in separate HTML input fields using one button. These values will be entered into a MySQL table called answers with 3 columns: answerID, questionID and answerBody.

However, each input field is generated using a while loop in a separate PHP function, with the form id being set to 'questions'.

Is it possible to do this?

Here is my code:

survey.php:

<?php

    require_once "config/config.php";
    
    //Start the session to grab session details
    session_start();

    //Process data when form is submitted
    if($_SERVER["REQUEST_METHOD"] == "POST")
    {

        //Check if fields are empty
        if (empty($_POST["answer"]))
        {
            //State error code
            $answerError = 'Please answer this question.';
        }
        else
        {
            //Set answer
            $answer = $_POST["answer"];
        }

        //Check if error variables have any values assigned
        if (empty($answerError))
        {
            //Prepare database insert
            $sql = "INSERT INTO answers (questionID, username, answerBody) VALUES (?,?,?)";

            //Check if the statement has the connect and sql variables
            if ($statement = mysqli_prepare($connect, $sql))
            {
                //Add variables to the statement
                mysqli_stmt_bind_param($statement, "sss", $paramQuestion, $paramUsername, $paramAnswer);

                //Set the parameter to the answer
                $paramQuestion = $_POST["questionID"];
                $paramUsername = $_SESSION["username"];
                $paramAnswer = $answer;
                

                //Execute statement with entered variable
                if (mysqli_stmt_execute($statement))
                {
                    //Redirect user to success page
                    header("location: thankyou.php");
                }
                else
                {
                    echo "Something went wrong. Please try again later.";
                }

                //Close statement
                mysqli_stmt_close($statement);
            }
        }

    }
?>

                $questionID = $row['questionID'];

                <input type="text" name="answer" size="50" />
            func

            </form>
            </div>
            </div>';

            }
        }
    }

Answer 1

You can't submit multiple forms via a submit form. You can either use XHR and send a request per form (which I don't recommend from a performance standpoint) or you can change your getQuestions function so that it just adds new inputs to a single existing form. For looping through it easily in your backend, you can use the array format for your input names ie questionID[] and answer[] .
