Could you point how to correctly call a Codeigniter method from jQuery?

Accordingly to:
$("body").on("click", ".call-ajax", function() {
		// obtém o valor do link
		console.log("chamada ajax");
  
		var caminho = "http://localhost/xxxxx/public/uploads/anexos/";
	   
	   
		data = {
		  id_rec: $(this).data("id_rec"),
		  anexo: caminho + $(this).data("anexo")
		};
	
		console.log(data);
	
		// AJAX para o controller
		$.ajax({
		  url: "reclamacao/delete_anexo",
		  data: data,
		  type: "POST"
		}).done(function(resp) {
			console.log("deleção OK");
		  // Display the resposne
		  //$("#result").append($("<li/>").html(resp));
		});
	  });

Open in new window


It correctly calls
img002

But this error occurs:
img001
Controller code:
public function delete_anexo($id, $file)
{
	try
	{
		if (!$this->input->is_ajax_request())
		{
			$this->output->set_status_header(404);
			return;
		}
		if (!$this->anexo_model_reclamacao->delete_anexo($id, $file))
			throw new Exception("Erro ao excluir", 1);

		$alert = 'Operação Realizada com sucesso.';
	}
	catch (exception $e)
	{
		$alert = $e->getMessage();
	}

	bootbox_alert($alert);
}

Open in new window



Model Code:
      public function delete_anexo($id, $file) {
        $this->db->delete($this->table, array('id_reclamacao' => $id, 'file' => $file));
        return true;
    }

Open in new window



Thanks in advance!

In your controller code, you're expecting the variables $id and $file to be passed as part of the URL So this:

public function delete_anexo($id, $file)

is expecting you to call it like so:

delete_anexo/1/file

In your jQuery code, you're POSTing the data to delete_anexo, so you need to get the variables from the post array

public function delete_anexo()
{
	try
	{
		if (!$this->input->is_ajax_request())
		{
			$this->output->set_status_header(404);
			return;
		}

		$id = $this->input->post('id_rec');
		$file = $this->input->post('anexo');

		if (!$this->anexo_model_reclamacao->delete_anexo($id, $file))
			throw new Exception("Erro ao excluir", 1);

		...
