Мои php и form не будут подключаться к моей базе данных, чтобы добавить значения

Question

Я создал форму, используя Bootstrap modal, соединение с базой данных через PHP, а также простую проверку формы. Когда я заполняю форму и нажимаю submit, она, кажется, подключается к базе данных, и ошибки формы не возвращаются. В нем указано: «пострадали -1 строки. Спасибо за ваш RSVP», но когда я смотрю на PHPMyAdmin, в моей базе данных нет значений.

Ниже мой PHP:

<?php 

//check if form is submitted and not a hack/bot. Checks to see if form is submitte by the post method then runs fxn. 
if ($_SERVER['REQUEST_METHOD'] == 'POST'){ 

    //grab all values that come from form in these variables. Each line below grabs info typed/selected in each form input. The value in square brackets is the name value of each input. Keep the $variables different from input names. 
    $rsvpvar = $_POST['rsvpBox']; 
    $fullnamevar = $_POST['fullName']; 
    $emailvar = $_POST['emailBox']; 
    $attendvar = $_POST['attend']; 
    $guestsvar = $_POST['extraGuests']; 
    $commentsvar = $_POST['additionals']; 

    //If fxn checks to see if all above variables have values stored in them using !empty fxn and if not if runs the echo. Use !empty (not empty) and not isset because isset will allow db connection even if some form values are blank. If there is a value stored in all form inputs then we incude this php or run the connetion to database. 
    if(!empty($rsvpvar) && !empty($fullnamevar) && !empty($emailvar) && !empty($attendvar) && !empty($guestsvar) && !empty($commentsvar)){ 

     //Define the below vaiables within parenthesis. 
     $hostname = "rsvp.db"; 
     $username = "******"; 
     $password = "******"; 
     $dbname = "rsvp"; 

     //Connection to mysql database. OR die drops connection to database for security reasons. Connect error gives message. 
     $dbc = mysqli_connect($hostname, $username, $password, $dbname) OR die("Could not connect to database, ERROR: ".mysqli_connect_error()); 

     //Set encoding 
     mysqli_set_charset($dbc, "utf8"); 

     //insert into table "rsvp" by getting or querying values stored in $dbc variable (db info). You insert into the corresponding rows of the db table (i.e. RSVP), then you grab what you're inserting using the VALUES. What you're inserting comes from the above variables. 
     mysqli_query($dbc, "INSERT INTO rsvp(RSVP, FULLNAME, EMAIL, ATTEND, GUESTS, COMMENTS) VALUES('$rsvpvar', '$fullnamevar', '$emailvar', '$attendvar', $guestsvar', '$commentsvar')"); 

     //define variable $registered which checks database to make sure values were inserted and rows were affected then outputs how many rows affected. Make sure the $dbc or connection info is inside parenthesis. 
     $registered = mysqli_affected_rows($dbc); 
     echo $registered." rows are affected. Thank you for your RSVP"; 

    }else{ 
     echo "ERROR: You did not fill out each section"; 
    } 
}else{ 
    echo "Please fill out everything on the RSVP form"; 
}

Пожалуйста, помогите, как я не являюсь специалистом по базам данных ...

Answer 1

Все ваши переменные POST:

$rsvpvar = $_POST['attending']; 
$emailvar = $_POST['emailBox']; 
$fullnamevar = $_POST['fullName']; 
$attend1var = $_POST['friday']; 
$attend2var = $_POST['saturday']; 
$guestsvar = $_POST['extraGuests']; 
$commentsvar = $_POST['additionals']; 

SO, должно быть условие:

if(!empty($rsvpvar) && !empty($emailvar) && !empty($fullnamevar) && !empty($attend1var) && !empty($attend2var) && !empty($guestsvar) && !empty($commentsvar)){ 

Пожалуйста, используйте тот же имя в поле ввода 2 радио:

<input type="radio" name="attending" id="attending" value="option1" checked>. 
<input type="radio" name="attending" id="notAttending" value="option2">
