Thanks for replying ZurdoDev. Smile | :)

I was thinking it had to be something in the prepared statement that I have done wrong but can't figure it out. I ran a query to create the table and columns so assume that must be correct?

Somewhere you should be able to get the details of the error. I don't do much php but if you aren't seeing the error when you run it then maybe look in the logs.

Two obvious problems:

You're inserting into three columns, but you've only specified two values:

PHP

$sql = "INSERT INTO users (email, username, password) VALUES (?, ?, ?)";

You've only specified types for two parameters, and you're missing a comma between the last two parameters:

PHP

mysqli_stmt_bind_param($stmt, "sss", $param_email, $param_username, $param_password);

I've fixed those errors but still having the same issue, it loaded the form once but now just a white page with the error.

I have played around starting again from the basic code and adding in what I need and checking for errors, all is fine till I put the code below in.

 }

// Validate email
if(empty(trim($_POST["email"]))){
    $email_err = "Please enter your email.";
} elseif(strlen(trim($_POST["email"])) < 6){
    $email_err = "email must have at least 6 characters.";
} else{
    $email = trim($_POST["email"]);
}

PHP

if(empty(trim($_POST["email"]))){

If the email variable is blank then calling trim on it will fail. You should change it to:

PHP

if(empty($_POST["email"])){

Richard, is there an error log generated somewhere for the DB? I get an intermittent fault (loads of folk saying the can't register but I can see some are able to) This is the error that shows on the form so not of much use. lol "Something went wrong. Please try again later".

Sorry, I don't know offhand. Check the MySQL documentation. I see that you are posting that message in your code. So you need to check why the call to mysqli_stmt_execute failed.

Thanks Richard,

I edited as you said the other night but wonder if my issue is somewhere in here?

if(empty($_POST["email"])){
     $email_err = "Please enter your email.";
 } elseif(strlen(trim($_POST["email"])) < 6){
     $email_err = "email must have at least 6 characters.";
 } else{
     $email = trim($_POST["email"]);
 }

Thanks Richard, progress made.

There is no error as such, if you try to register with the same email twice (yes I thought that as well) it throws the error I mentioned but isn't telling them the email is already registered. It does for username but the email was the bit I added in. Smile | :)

Reporting data

Hi all,

I've done a small database and PHP based web page to be able to track my working hours easily.

Last week a customer asked me how many time in total each month I had spend in one project and I had to get all the times, filter by month manually and sum it all to give him an answer... a matter of 10 minutes, but I want to automate this kind of things...

My question is:

I will have a table that will be able to be grouped by day, week, month, year or not grouped, but then, I have to get the sum of all hours that I worked in my office, the sum of the hours that I worked out of my office, the sum of the hours travelling...

I can only think of doing something like

SQL

SELECT  sumA,
        sumB,
        sumC
FROM
(
  SELECT sumA,
         type,
         "0" as sumB,
         "0" as sumC
  From table1

  WHERE type = A

UNION ALL

  SELECT sumB,
         type,
         "0" as sumA,
         "0" as sumC
  From table1

  WHERE type = B

UNION ALL

  SELECT sumC,
         type,
         "0" as sumA,
         "0" as sumB
  From table1

  WHERE type = C
)
AS VIEW1

Is this the way to do it?

I want to show the data in columns:

            Hours at the office   |   hours out of the office   |   hours travelling
_____________________________________________________________________________________________________
JANUARY    |                      |                             |
_____________________________________________________________________________________________________
FEBRUARY   |                      |                             |
_____________________________________________________________________________________________________
MARCH      |                      |                             |
_____________________________________________________________________________________________________
APRIL      |                      |                             |
_____________________________________________________________________________________________________
...

And I would like to solve this in the database part, not creating different tables and then working in the PHP area...

Sorry for this way too much generic question, I hope I made it clear enough for you to enlighten me.

Thank you in advance!

Wrong tools for the jobs, database for servicing your data query and PHP for the presentation.

You could store your queries in a table, relate them to a query/stored proc and expose a title in a combo box for the user to select. Display would need to be an auto generated table to support different result sets.

The problem with this is that you may need to support different filtering parameters and you end up with an entire framework to support the reporting when it is faster and simpler to build a result page and query for each report request.

hmmmm...

I meant this: I have all the data in the database, create a query and get the results that I show then in the web page using PHP.

I have all the "framework" done already, I can tune the queries easily filtering data, ordering and grouping at will...

But, maybe it would be much easier to create a "view" in PHPMyAdmin (I still don't know if this can be achieved but I'll look for it) and then the queries would be much easier.

After having the view, I would not have to create endless joins to get the data mixed correctly.

What database are you using?

If it is MS-SQL, then there is a command call PIVOT which will do exactly what you want to do.

MariaDB in this case, but thanks I'll take a look at PIVOT and see if there is something similar.

how to create relationship between tables based on field

Cenator13-Jun-20 2:12

Cenator

13-Jun-20 2:12

First of all: "Sorry for my english!" I recently have created a calibration database via Ms Access DBMS. Here is the model:

https://i.stack.imgur.com/Z2uBf.jpg[^]

Each tool has "name abzarLa" field that is actually "Tool's English Name" that comes from ToolList Table. Here is sample values of "ToolList" Table.

https://i.stack.imgur.com/cPwSk.jpg[^]

now it's time to explain my problem: each Tool based on its "name abzarLa" relates to its specific "Data Table" which contains Calibration data results with specific fields. (One To Many relationship => each tools has multiple row in "Data Table") Here is data table that uses for insert "Pressure gauge" results:

https://i.stack.imgur.com/ZEQ7e.jpg
[^]

And here is data table that uses for insert "Oven", "incubaor", "cold Incubator" results:

https://i.stack.imgur.com/4uzOp.jpg[^]

Ok, So we have a Tools table and multiple "Data Tables". How can I design "Data Tables" and create relationship between "Tools" table and "Data Tables" base on "name abzarLa" field?
One Design is:

https://i.stack.imgur.com/6bhdu.jpg[^]

but I want each tool only relates with its specific [Data Table]

Relationships are defined between tables, not records. Your parent table will need a relationship to all relevant tables. Your query can then join to those tables depending on the data in the parent record.

You can use a newer driver without any problems.
So either you get the nuget package Oracle.ManagedDataAccess, which I strongly suspect isn't existing on VS2012.
So you can download the client from here: Oracle Data Access Components (ODAC) for Windows Downloads[^]
