CI Post to Controller

Question

I am having a bit of a nightmare with a CI build today and I am hoping that the clever stck community can bail me out :)

I have a model, view and controller named comment_m.php (model), comment_v.php (view) and comment.php (controller) in CI installation.

The issue I am facing is that it doesn't seem to be getting inside the controller method and therefore is not inserting to the database.

The URL of the page is http://localhost/comment/1234 if that makes any difference, for some reason I am not getting any errors and when I try and use log_message() it is not writing.

Can anyone see anything obvious or indeed stupid that I am doing here which could be causing the problems?

PHP / HTML

<?php
$cattributes = array('id' => 'newComment', 'enctype'=>"multipart/form-data");
echo form_open('comment/saveComment', $cattributes);

Answer 1

If your Controller is not getting hit, you may have a routing problem.

If your Class/Method are spelt incorrectly, or don't relate to actual naming conventions, use the route file to make one.

application/config/routes.php

$route['comment/save'] = 'class/method';

---

Error Reporting

Inside application/config/confg.php, make sure your messages are enabled(development mode only)

$config['log_threshold'] = 1;

---

Enctype

Save you some steps, use form_open_multipart('comment/save', array('id'=>''))

---

Accessing Inputs($_POST,$_GET,$_FILE)

Use the Input library $this->input->post as it will retrieve the Globals for you and at a very basic level sanitize the input fields for you if you have XSS enabled.

---

Form Validation

Always validate user inputs, even if they are admins. Again never use Globals such as $_POST, The input library will somewhat protect against XSS, however if your field is an integer type, validate it as one with the form_validation library.
