I intend to do a record deletion from a table with php and javascript, but when calling the function that the Delete does, it does not do anything.

With this code I call the function

<?php
  if (isset($_POST["delete-contrato-select"])) { 
       $idContratoSelect = $_POST['id_tipo_contratoDelete'];
       $CbContratoController -> delete($idContratoSelect);
  }
?>

This is my function where the Delete is

<?php

 class CbContratoController {

   function delete($id_tipo_contrato){ 
      require_once ('conex/conex.php'); 
      $sqlDelete="DELETE FROM tipo_contrato WHERE id_tipo_contrato = '".$id_tipo_contrato."'";  
      $res = $conex->query($sqlDelete);
   }

 }

?>

And here I get the registration id

 function deleteCbContrato(id_tipo_contrato){     
  document.formDeleteContrato.id_tipo_contratoDelete.value = id_tipo_contrato;                

  $('#myModalDelete').on('shown.bs.modal', function () {
      $('#myInput').focus()
  });


}

Delete button

 <button id="delete-contrato-modal" name="delete-contrato-modal" type="button" class="btn btn-link btn-danger btn-just-icon remove" onclick="deleteCbContrato('<?php echo($row_herramientas['id_tipo_contrato']); ?>');"><i class="material-icons" data-target="#myModalDelete" data-toggle="modal" >close</i></button>

Modal code where I get the id_type _contract

 <div class="modal fade" id="myModalDelete" tabindex="-1" role="dialog" aria-labelledby="myModalDeleteLabel">
            <div class="modal-dialog" role="document">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                        <h4 class="modal-title" id="myModalDeleteLabel">Eliminación de Registro</h4>
                    </div>

                    <form role="form" name="formDeleteContrato" method="post" action="contratos.php">
                        <div class="modal-body">                                    
                                <div class="input-group">
                                <label for="id_tipo_contrato">¿Desea eliminar el registro seleccionado?</label>
                                </div>       
                                <div class="input-group">
                                 <label for="id_tipo_contrato">Registro: </label>
                                 <input type="text" readonly class="form-control" id="id_tipo_contratoDelete" name="id_tipo_contratoDelete" >                                        
                                </div>
                        </div>

                        <div class="modal-footer">
                                <button id="delete-contrato-select" name="delete-contrato-select" type="submit" class="btn btn-primary">Aceptar</button>                                        
                                <button id="cancel"type="button" class="btn btn-default" data-dismiss="modal">Cerrar</button>   
                        </div>

                    </form>
                </div><!-- /.modal-content -->

Let's say you have an App class inside the file "App.php" ;

class App
{

public function hello(){
    echo "hello word";
}

}

To call that method from another site you have to create an object of the App class;

require("App.php");  //Indicas que vas autilizar ese archivo

$app = new App();  //guardas en $app una instancia de la clase App

$app->hello(); //eso deberia ejecutar el metodo hola mundo!

I hope that with this example you will have a little idea for your problem.

If you are not going to instantiate the class "CbContratoController" from where you call the delete method, then you must make that method ("delete") within the class static, like this:

<?php

class CbContratoController {

  public static function delete($id_tipo_contrato){
    ...
  }
}

And you would call it like this:

<?php

require_once('CbContratoController.php');

if (isset($_POST["delete-contrato-select"])) { 
  $idContratoSelect = $_POST['id_tipo_contratoDelete'] ;
  CbContratoController::delete($idContratoSelect); 
}

But the best practice would be to make an instance of "CbContratoController", like this:

<?php

require_once('CbContratoController.php');

if (isset($_POST["delete-contrato-select"])) { 
  $idContratoSelect = $_POST['id_tipo_contratoDelete'];
  $contratoCtrl = new CbContratoController();
  $contratoCtrl->delete($idContratoSelect); 
}

And your delete method should no longer be static:

<?php

class CbContratoController {

  public function delete($id_tipo_contrato){
    ...
  }
}
