Submit multiple forms that are created in PHP while loop with one button
تبليغسؤال
يرجى شرح بإيجاز لمإذا تشعر أنك ينبغي الإبلاغ عن هذا السؤال.
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);
}
}
}
?>
