php form submit isnt inserting into the database - php

Question

Right, this should be very basic php, however i cannot for the life of me figure out why this is not working.
I have a form which when submit it should grab the fields then insert the data into the database. I have on my index.php a section which actually pulls back info from database and works fine so i cant see this being a connection problem.
db_connection.php i have hashed out the info here as its for my database, but everything is correct
<?php
define("DB_SERVER","**********");
define("DB_USER","*************");
define("DB_PASS","*********");
define("DB_NAME","reviews");
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS,DB_NAME);
if(mysqli_connect_errno()){
die("database connection failed");
}
?>
functions.php
<?php
function redirect_to($new_location) {
header("Location: " . $new_location);
exit;
}
function confirm_query($result){
if(!$result){
die("database query failed");
}
}
function find_reviews($connection){
$query = "SELECT * ";
$query .= "FROM reviews";
$result = mysqli_query($connection,$query);
confirm_query($result);
while($reviews = mysqli_fetch_assoc($result)){
$output = "<li class=\"first\">";
$output .= $reviews["name"];
$output .= "</li>";
$output .= "<li class=\"second\">";
$output .= $reviews["company"];
$output .= "</li>";
$output .= "<li class=\"third\">";
$output .= $reviews["comment"];
$output .= "</li>";
$output .= "<li class=\"line\"></li>";
echo $output;
}
mysqli_free_result($result);
return $reviews;
}
?>
index.php
to note with this, the function find_reviews() works and does grab the information from database. Also the above "db_connection.php" and "functions.php" are required in index.php
<?php
require("includes/header.php");
$page_title = "All County Road Markings";
$description = "Specialising in Road Marking & Car Park Lining. We are a professional established road marking service with over 20 years experience";?>
<?php require("includes/db_connection.php"); ?>
<?php require("includes/functions.php"); ?>
<?php if(isset($_POST["submit"])){
$name = $_POST["name"];
$company = $_POST["company"];
$comment = $_POST["comment"];
$query = "INSERT INTO `reviews` (name,company,comment) VALUES ('$name','$company','$comment')";
$result=mysqli_query($connection,$query);
confirm_query($result);
redirect_to("index.php");
}
?>

ok so can anyone see anything that i am doing wrong? as when the form is submitted it is just not inserting into the database.
EDIT::
when i try echo mysqli->error; i get following error:
Parse error: syntax error, unexpected T_OBJECT_OPERATOR, expecting ',' or ';' in /hermes/bosoraweb140/b484/ipg.allcountyroadmarking/index.php on line 17
So i changed it to
if(!results){
echo "hello";
}
and i do not see the "hello" so it is indicating that i am not even getting into the part that it deals with the post fields
SELF RESOLVED:::::
Ive fixed it, i changed action="index.php" to action=""
i dont understand, it should have worked , but for some reason having the action blank worked. both should be acceptable !

Answer 1

The if statement for $_POST['submint'] might be false on every submit. Maybe try !empty($_POST)

Answer 2

The form action which was set to
<form action="index.php" method="POST">
did not work, however i do not see why not as it is referencing the current page.
However changing it to this resolved the problem.
<form action="" method="POST">

Answer 3

Well you got the php in the same file so that maybe why the action="" is working if it defaults to the same page.. action="index.php" should prepend the current web address. Maybe try putting the full web address in the action="the url for index.php" to see if that works. If does then action="index.php" must not be going to the right file.
