Error:

these are the error comming in my code

please will anybody help me

It's $con first. So where you have $sql, $con etc, change it to $con, $sql

The error literally told you what you needed to do.

have changed but it just came
Error:

Here are your problems.

connection

$con = mysqli_connect("localhost","root","","register");

Second, the mysqli_select_db...

mysqli_select_db("register", $con);

If you want to use the mysqli_select_db, then connection syntax should be like this.

$con = mysqli_connect("localhost","root","");

then we can use

mysqli_select_db("register", $con);

In mysqli , the error reporting should be written like this. Waring! this is for the development environment only..

 $con = mysqli_connect("localhost","root","");

    if (mysqli_connect_errno()){

      echo "Failed to connect to MySQL: " . mysqli_connect_error();

   }

    ## add the rest below

you need to use prepared statements and bind parameters.

@veedeoo — The errors he has indicated to me that he needs $con, "register"

ok thanks everybody, the problem solved

John — mark it as solved.

Apart from your error, you are mixing mysql and mysqli functions. Don't do that.

Merci beaucoup!!!

Good Morning,

I've wasted a lot of time on the subject, but the time is short for delivery of a college job.
It may be that I do not know how to use the correct terms to get help.
I need this urgent help. Help me please.

I have the client registry, with some fields, but I need to get information from the profession table and save in the clients table. Making a select in the combobox where it is showing the professions.

I have the connection file.php working perfectly. And also the file form-client.php and form-process.php
If you need, I can send to identify the error.
Because I can not make the select of the field proffession (tb_profession) inside the form-client.

Tb_client (cli_id, cli_name, cli_phone, pro.session_id)

Tb_profession (pro_profession, pro_profession)

Mysql database

Att,

I will be very grateful.
