Using Get And Prepared Statements

[SteveNI]

Hi everyone, my first post!

I hope you can help me I am having terrible problems solving an issue.

I am designing a website with php and mysql, it will allow a user to record their bank accounts, credit card loan details etc (dont worry its a project and not for general use so it not malicious!).

They will also be able to store their transactions, credits and debits to and from those accounts

At present the transaction database contains all the credits and debit for every account and the home page has a list of all the accounts that the customer has registered.

What I am trying to do is when the user is on the home page they click on a link for an account and this will display for them all credits and debits associated solely with that account. So lets say on the home screen there is a list:

Steve Current Account

Steve CreditCard Account

 

Where I to click on Steve Current Account it will then display:

Credit Debit Catagory

200 - salary

- 100 Food

 

etc

Apologies for this being a longwinded first post but I have been banging my head against a brick wall for two days now! It seems straightforward enough but I am very much a newbie when it comes to this. Would anyone know how to approach this or are there any videos on the site that may help.

The current code that I am using that isnt working is

<?php
//connect to database
   include ('connect-To-db.php');
       $id = $_GET['id'];
       global $mysqli;
       echo "$id";
      $stmt = $mysqli->prepare("SELECT t.Credit, t.Debit, t.Catagory,a.Accname
          FROM transactions as t LEFT JOIN account as a ON a.Accname=t.Accname
          WHERE a.accID=?");
      echo $mysqli->error;

      $stmt->bind_param("i", $id);
        if($stmt->execute()){
           //$stmt->bind_result($cred, $deb, $cat,$Accname);


           $stmt->fetch();
           $stmt->store_result();
               if ($stmt->num_rows>0){
                   //echo "Search worked";
                   //echo "<p><b>$Accname</b>: Credit: $cred, Debit: $deb, Category: $cat</p>";
                    $stmt->bind_result($cred, $deb, $cat, $Accname); 
                       while($stmt->fetch())                              
                           {
                               echo "<p><b>$Accname</b>: Credit: $cred, Debit: $deb, Category: $cat</p>";
                            }
               }
               else{
                   echo "Search didnt work";
               }
           }

               else {
                   echo "QUERY ERROR: ".$mysqli->error;
               }
?>

When you run this code, what are you getting? Error messages? Blank screen? Something else?
