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. 
|
|
|
|
|
Did you not realise that you first need to check whether the email is already registered?

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
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.

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.

Bonjour,
Sous visuel studio 2012, je développe une application web .net. J'ai besoin de connecter à une base des données oracle 9i. Je suis en train de chercher un driver pour l'ajouter comme référence dans l'application afin d'interroger la base. Le problème que je n'ai pas trouvé sur le net un driver oracle 9i
Où se trouve ce driver ? Comment l'installer et l'utiliser ?
Merci d'avance pour toute aide.

Bonjour,
Merci
Jörgen Andersson but 32 bit Or I have windows 64 bit
I find alaways client oracle 11g for windows 64 bit in visual studio 2012
|
|

Visual studio is 32bit so you will not be able to debug unless you use a 32-bit client.
If it is a web application it will automatically run as a 64-bit application which is a bit problematic, so you will have to set the application pool to run as a 32-bit application.

This means you're trying to run a 64-bit program in a 32-bit environment or the opposite way around.
I'm Assuming you have installed a 32-bit client.
IIS is running all it's processes as 64 bits by default, which means it crashes if the oracle client is 32 bits.
You can change this by creating a new Application Pool for your web application, and open "Advanced settings" and "Enable 32-bit Applications".

It could be virtually anything. Any luck connecting to the same server with the same credentials but with a different Mysql IDE?

The text below is from "Introduction to Database Systems, J. Date". I can't the bolded part. why since Relvar constraints must obviously be checked immediately, must database constraints be checked immediately too? Why database constraints must follow relvar constraints, please?
The previous edition of this book stated that relvar constraints were checked immediately but database constraints were checked at end-of-transaction (a position that many writers concur with, though they usually use different terminology). But The Principle of Interchangeability (of base and derived relvars--see Chapter 9) implies that the very same real-world constraint might be a relvar constraint with one design for the database and a database constraint with another! Since relvar constraints must obviously be checked immediately, it follows that database constraints must be checked immediately too. .
