capturing data using dropdown menu,radio buttons in mysql - php

Question

I am making a simple registration form with radio button and a drop-down menu.
My problem is I cannot insert form data into my database. I think I am not capturing the form data but I am not sure.
Because when I submit the form I get the error SORRY! ERROR while inserting record ! which is telling me it failed to insert.i have tried to add
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(E_ALL);
so that i see the actual errors displayed on my page but i still can not see to figure out what is it that i'm doing wrong.
Page code:
<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(E_ALL);
include_once 'dbconfig.php';
if(isset($_POST['btn-save']))
{
$fname = $_POST['first_name'];
$lname = $_POST['last_name'];
$employee_nrc = $_POST['employee_nrc'];
$Phone = $_POST['phone_no'];
$Businesstype = $_POST['business_type'];
$Businesssite = $_POST['business_site'];
$Businessactivity = $_POST['business_activity'];
if($crud->create($fname,$lname,$employee_nrc,$Phone,$Businesstype,$Businesssite,$Businessactivity))
{
header("Location: add-data.php?inserted");
}
else
{
header("Location: add-data.php?failure");
}
}
?>
<?php include_once 'header.php'; ?>
<div class="clearfix"></div>
<?php
if(isset($_GET['inserted']))
{
?>
<div class="container">

Answer 1

Your issue is that you have not properly coded the <input> tags in your HTML.
Each <input> tag required a name="" attribute as it is this attribute and not the id="" that the browser uses to create the name=value pairs that are sent as $_GET or $_POST variables
So amend your code and add a name="" attribute ro all the input tags like so :-
<input type="text" name="first_name" class="form-control" id="inputFirstName" placeholder="first name">
and so on for all the input fields, making sure the names you give to each input match the names you are using in your PHP code.
Also make sure that the name="last_name" is the same as the $_POST['last_name'].
Case should also match, so name='Employee NRC' and $_POST['employee_nrc']; do not match and wont work. Also dont put spaces in the name='Employee NRC' either remove spaces or us an underscore _ in the name like name='employee_nrc'.
