  • How to do MVC the right way

    - by Ieyasu Sawada
    I've been doing MVC for a few months now using the CodeIgniter framework in PHP but I still don't know if I'm really doing things right. What I currently do is: Model - this is where I put database queries (select, insert, update, delete). Here's a sample from one of the models that I have: function register_user($user_login, $user_profile, $department, $role) { $department_id = $this->get_department_id($department); $role_id = $this->get_role_id($role); array_push($user_login, $department_id, $role_id); $this->db->query("INSERT INTO tbl_users SET username=?, hashed_password=?, salt=?, department_id=?, role_id=?", $user_login); $user_id = $this->db->insert_id(); array_push($user_profile, $user_id); $this->db->query(" INSERT INTO tbl_userprofile SET firstname=?, midname=?, lastname=?, user_id=? ", $user_profile); } Controller - talks to the model, calls up the methods in the model which queries the database, supplies the data which the views will display(success alerts, error alerts, data from database), inherits a parent controller which checks if user is logged in. Here's a sample: function create_user(){ $this->load->helper('encryption/Bcrypt'); $bcrypt = new Bcrypt(15); $user_data = array( 'username' => 'Username', 'firstname' => 'Firstname', 'middlename' => 'Middlename', 'lastname' => 'Lastname', 'password' => 'Password', 'department' => 'Department', 'role' => 'Role' ); foreach ($user_data as $key => $value) { $this->form_validation->set_rules($key, $value, 'required|trim'); } if ($this->form_validation->run() == FALSE) { $departments = $this->user_model->list_departments(); $it_roles = $this->user_model->list_roles(1); $tc_roles = $this->user_model->list_roles(2); $assessor_roles = $this->user_model->list_roles(3); $data['data'] = array('departments' => $departments, 'it_roles' => $it_roles, 'tc_roles' => $tc_roles, 'assessor_roles' => $assessor_roles); $data['content'] = 'admin/create_user'; parent::error_alert(); $this->load->view($this->_at, $data); } else { $username = $this->input->post('username'); $salt = $bcrypt->getSalt(); $hashed_password = $bcrypt->hash($this->input->post('password'), $salt); $fname = $this->input->post('firstname'); $mname = $this->input->post('middlename'); $lname = $this->input->post('lastname'); $department = $this->input->post('department'); $role = $this->input->post('role'); $user_login = array($username, $hashed_password, $salt); $user_profile = array($fname, $mname, $lname); $this->user_model->register_user($user_login, $user_profile, $department, $role); $data['content'] = 'admin/view_user'; parent::success_alert(4, 'User Sucessfully Registered!', 'You may now login using your account'); $data['data'] = array('username' => $username, 'fname' => $fname, 'mname' => $mname, 'lname' => $lname, 'department' => $department, 'role' => $role); $this->load->view($this->_at, $data); } } Views - this is where I put html, css, and JavaScript code (form validation code for the current form, looping through the data supplied by controller, a few if statements to hide and show things depending on the data supplied by the controller). <!--User registration form--> <form class="well min-form" method="post"> <div class="form-heading"> <h3>User Registration</h3> </div> <label for="username">Username</label> <input type="text" id="username" name="username" class="span3" autofocus> <label for="password">Password</label> <input type="password" id="password" name="password" class="span3"> <label for="firstname">First name</label> <input type="text" id="firstname" name="firstname" class="span3"> <label for="middlename">Middle name</label> <input type="text" id="middlename" name="middlename" class="span3"> <label for="lastname">Last name</label> <input type="text" id="lastname" name="lastname" class="span3"> <label for="department">Department</label> <input type="text" id="department" name="department" class="span3" list="list_departments"> <datalist id="list_departments"> <?php foreach ($data['departments'] as $row) { ?> <option data-id="<?php echo $row['department_id']; ?>" value="<?php echo $row['department']; ?>"><?php echo $row['department']; ?></option> <?php } ?> </datalist> <label for="role">Role</label> <input type="text" id="role" name="role" class="span3" list=""> <datalist id="list_it"> <?php foreach ($data['it_roles'] as $row) { ?> <option data-id="<?php echo $row['role_id']; ?>" value="<?php echo $row['role']; ?>"><?php echo $row['role']; ?></option> <?php } ?> </datalist> <datalist id="list_collection"> <?php foreach ($data['tc_roles'] as $row) { ?> <option data-id="<?php echo $row['role_id']; ?>" value="<?php echo $row['role']; ?>"><?php echo $row['role']; ?></option> <?php } ?> </datalist> <datalist id="list_assessor"> <?php foreach ($data['assessor_roles'] as $row) { ?> <option data-id="<?php echo $row['role_id']; ?>" value="<?php echo $row['role']; ?>"><?php echo $row['role']; ?></option> <?php } ?> </datalist> <p> <button type="submit" class="btn btn-success">Create User</button> </p> </form> <script> var departments = []; var roles = []; $('#list_departments option').each(function(i){ departments[i] = $(this).val(); }); $('#list_it option').each(function(i){ roles[roles.length + 1] = $(this).val(); }); $('#list_collection option').each(function(i){ roles[roles.length + 1] = $(this).val(); }); $('#list_assessor option').each(function(i){ roles[roles.length + 1] = $(this).val(); }); $('#department').blur(function(){ var department = $.trim($(this).val()); $('#role').attr('list', 'list_' + department); }); var password = new LiveValidation('password'); password.add(Validate.Presence); password.add(Validate.Length, {minimum: 10}); $('input[type=text]').each(function(i){ var field_id = $(this).attr('id'); var field = new LiveValidation(field_id); field.add(Validate.Presence); if(field_id == 'department'){ field.add(Validate.Inclusion, {within : departments}); } else if(field_id == 'role'){ field.add(Validate.Inclusion, {within : roles}) } }); </script> The codes above are actually code from the application that I'm currently working on. I'm working on it alone so I don't really have someone to review my code for me and point out the wrong things in it so I'm posting it here in hopes that someone could point out the wrong things that I've done in here. I'm also looking for some guidelines in writing MVC code like what are the things that should be and shouldn't be included in views, models and controllers. How else can I improve the current code that I have right now. I've written some really terrible code before(duplication of logic, etc.) that's why I want to improve my code so that I can easily maintain it in the future. Thanks!

  • Enable Cisco ASA as an SSH Tunneling

    - by Jim
    I am trying to utilize my Cisco ASA as a SSH Tunnel. I've configured this before when using a Linux server as the SSH target, however I cannot seem to get it to work with the ASA. I have configured and enabled SSH on the Cisco ASA, as well as a username that I can SSH to the console, however the SSH Tunneling feature does not work. For example, on my PC I use Putty with a Local Tunnel defined to a server behind the ASA. I should be able to (if SSH connected to the ASA) be able to access the server. See screenshot of putty. has anyone come across this before? Again this is to use my Cisco ASA as a SSH tunnel, this is not a port forwarding. -Jim

  • XP Restart After Power Failure

    - by Jim
    Hello, I've almost got my power settings sorted and was hoping someone could help? If I'm running XP and the power is cut, when the power is restored my machine auto restarts (this is what I want!) However, if I shutdown my machine properly (from the start menu & without touching the PC power button!), then switch the power off at the socket, then switch the power back on, the PC does not automatically restart. It's like the bios(?) recieives a message saying "aha, genuine shutdown and not a power cut, therefore do not restart on power restore." I want my PC to restart everytime it sees power restored from the socket? Any way round this? Anyone seen this before? I've upgraded my bios. Thanks in advance, Jim

  • Finding throuput of CPU and Hardrive on Solaris

    - by Jim
    How do i find the throughput of a CPU and the Hardisk on an open solaris machine. Using MPstat or iostat. I'm having a hard time identifying the throughput if it is given at all in the commands output. Eg. in mpstat there is very little explanation as to what the columns mean http://docs.sun.com/app/docs/doc/816-5166/mpstat-1m?l=en&a=view&q=syscl+mpstat I've been using the syscl column divided by time interval to find the throughput but to be honest i have no idea what a system call truelly is. I'm trying to to analyze a hardrive and CPU while writing a file to the hardisk and when at rest Thanks in advance. Jim

  • Dell Vostro 1520 Unable to Read Compact Flash Card with Adapter?

    - by Jim Taylor
    I Purchased the Dell Vostro 1520 a few months ago and recently tried using a PCMCIA adapter for the Compact Flash card my camera uses. I can't get the laptop to find the card. Tried going online to see if a CF card should work, but have not found a clear or definate answer. I do not want to deal with Dell on the phone as even 800 #'s cost me more than it's worth to use. Hoping someone can let me know if I'm wasting my time trying to get the laptop to read my CF card. It's the only type card I have to try the input slot, so can't test to see if the input slot even works. Thanks, -- ‹(•¿•)› Jim

  • Can't connect Alienware M11x wireless to internet thru families router

    - by Jim Kron
    Morning All, Have an Alienware M11x loaded with Win 7 Premium with the Dell half card wifi. Also have a Netgear and Belkin USB external adapters (b/g and N to include dual radios. No joy either. Families Internet is served thru Charter and they use a Motorola Router. No matter if we reset the router, I cannot connect to the Net but can talk to the router. BTW... my brother only uses WEP as a number of connected items are old and my folks are not in a high threat area for attacks. Frustrated, as I know what I'm doing but this really has me stumped. Any thoughts? Much appreciated, Jim

  • Windows7 home 64bit + Outlook 2010, multiple non-concurrent users

    - by Jim Taylor
    We have one windows computer shared by eight people. I have set up separate login accounts for each user. One account has administrative privileges, the others are standard users. We installed Outlook 2010 with the intention that each user could access their own email separately, without seeing the mail of other users. This has not worked as we intended. When the administrator logs in to each standard user account and starts the outlook mail setup, he is prompted for the administrative password, and then sets up the mail account. When accessing the outlook mail program after setup, each mail account shows as a separate tab in a communal inbox, rather than a separate mail box for each user. How would we accomplish the desired separation of Outlook mail accounts? Thanks for your advice Jim T.
