Mysql PHP query with filtering by various criteria

Good morning, fellas. I have a church membership database. I made a table to view these records, but as my BD has 39 columns, I took only the most important, and at the end of the line I put a link to the complete record.

On this home page where all the records appear, I put 7 selects (combobox) to do a filtering combining situations.

The selects are:

Selects will not be filled dynamically. Values are fixed.

I want that, when entering the page, the user receives the list of all the records. And by clicking, for example, in situation (member), sex (M) and status(absent), and receiving data from all male members who are absent.

And other combinations too.

I already managed to return the value with all the records when entering the page, and this part is working. . The results appear correctly in the table.

So I added the selects, already populated, and the button.

And now I need help: How do I mount the query so that, when clicking the button, it meets the selected criteria? Since, if any select is empty, it must return all records, but if it is marked, return only those corresponding. If anyone can help...

Below follows my complete code:


  if (!isset($_SESSION)) session_start();

  if (!isset($_SESSION['UsuarioID'])) {

      session_destroy();
      header("Location: login.html"); exit;
  }


include("classe/conecta.php");

$consulta = "SELECT Cod,Nome,Tel,Cel,Email,DtNasc,Status FROM CadPessoas order by Nome";
$con = $mysqli->query($consulta) or die($mysqli->error);

?>

There is no answer just for that, what I would do is this:

In each select put an option called "Ignore" as default

Do a query with the beginning of the query like this

$query = "SELECT Cod,Nome,Tel,Cel,Email,DtNasc,Status FROM CadPessoas where ";

then you test to see if it came as ignore or not and will complete the query, thus:

if ($sexo != "Ignorar"){

$query .= " sexo = $sexo and"; 

}

Repeat this with each criterion and at the end put

$query.= " order by nome";

Then note that the query will end and order by nome then you have to use replace to subtitle and order by order only.

Do not worry about the negativity of the question, the question is ok, what is not ok is the ego of these guys who think the question is not up to its inflamed ego.

Skewer give you direction.
