if (!mysqli_query($link, $insert)) {
          $msg = "Error inserting data";
        } else {
          $msg = "Record succesfully added";

        $phc = $cd1 = $cf1 = $ct1 = $crc1 = $ncb1 = $cd2 = $cf2 = $ct2 = $crc2 =
        $ncb2 = "";
        }
        mysqli_close($link);
  }

That is the If statment I have used to check for successful entry.  Right at the top of my form it has the following statement: Error inserting data! which is written in my If statement.  I have not input anything into the form and it displays this message.

I am thinking it has something to do with my db connection.

db connection - include 'includes/db_conn.txt';

In the .txt I have written this:
<?
$link =
        mysqli_connect('host','username','password','db_name');

In that format!
?>

But no joy!! it still wont insert into my db.

Help!!

Well i dont know a lot about mysqli, but:

You are going to need to change your included database connection file to a php file otherwise it isn't going to pass the information.

Also, if you think you are having troubles with your database connection, try the examples on the php website:

if you do this
[code]
if ($_POST) {

  $msg = "";

  foreach($_POST as $k => $v) {
        $v = trim($v);
        ${$k} = $v;// to create a variable from a variable you'll need the { and } around it, as of php5 i guess, it worked when i still got php4

        if ($v=="") {
          $msg = "Please fill in all fields";
        }
  }
[/code]

then you don't have to do this:

[code]
$phc = isSet($_POST['phc']) ? $_POST['phc'] : '';
$cd1 = isSet($_POST['cd1']) ? $_POST['cd1'] : '';
$cf1 = isSet($_POST['cf1']) ? $_POST['cf1'] : '';
$ct1 = isSet($_POST['ct1']) ? $_POST['ct1'] : '';
$crc1 = isSet($_POST['crc1']) ? $_POST['crc1'] : '';
$ncb1 = isSet($_POST['ncb1']) ? $_POST['ncb1'] : '';
$cd2 = isSet($_POST['cd2']) ? $_POST['cd2'] : '';
$cf2 = isSet($_POST['cf2']) ? $_POST['cf2'] : '';
$ct2 = isSet($_POST['ct2']) ? $_POST['ct2'] : '';
$crc2 = isSet($_POST['crc2']) ? $_POST['crc2'] : '';
$ncb2 = isSet($_POST['ncb2']) ? $_POST['ncb2'] : '';
[/code]

I'm no pro :) but the db connection code seems to be off. Here's yours:

[code]I am thinking it has something to do with my db connection.

db connection - include 'includes/db_conn.txt';

In the .txt I have written this:
<?
$link =
        mysqli_connect('host','username','password','db_name');

In that format!
?>[/code]

First, there's a misspell at 'mysqli' which should be 'mysql' without the 'i' in there.

Second, typically it's supposed to be this way:

[code]mysql_connect('host', 'username', 'password') or die("Where is that dang database");
mysql_select_db('db_name') or die("Where is that dang database!");
[/code]

I'm not 100% sure on this also but the included file should probably be a .php extension instead of the .txt.

UPDATE: I just noticed another thread pertaining to the 'mysqli' issue. Apparently that's a hybrid style of MySQL with 'Improved' tacked on. My apologies for mentioning the misspell. :)

I have changed the extension on the included file to .php, but It still keeps coming up with the same message: 'Error inserting data'. I have to use the isSet function as it prints notices in my form inputs if I dont.

Any other suggestions??

The problem and reason you're having to use the isset function is due to the form stating 'values' for the various fields that are dependent upon the form being parsed first. In other words, the form ACTION is pointed to PHP_SELF which would require the submit button hit before the actual values you have indicated can be displayed in the form fields. Not sure why you want to do that but hey.... :)

[code]VALUE="<? echo $phc ?>"[/code]

You're asking the form to display something that hasn't been invented yet until they fill out the form and hit submit. Then it will parse these via the $_POST command and display them. But, you're asking them to be displayed right back in the form fields. That's cool if you want to show them the form again with their entries placed in the respective fields.

For the data insert error, this is a wild guess, but try moving your include/db_conn.db line [i]ahead[/i] of your query statement. It needs that information present before executing your query command.
