What Is Wrong With My Logic?

[RalphLeMouf]

Hello -

 

I am trying to set up a forgot password system on my site. I am at the first step: which is creating a page where a person enters their email and if the email exists in the database. send them an email with a unique hashed and salted extension to verify security.

 

I have commented out all of my steps and my logic seems to spot on, however my newness to code-igniter I may be accidentally skipping a step or something else?

 

I am using my model to solely query the db and check against what is entered from the user. The errors I am getting are:

 

 

 

A PHP Error was encountered

 

Severity: Notice

Message: Undefined variable: query

Filename: controllers/auth.php

Line Number: 142

 

Fatal error: Call to a member function result() on a non-object in /Users/michaelsanger/Sites/cl_ci_new/application/controllers/auth.php on line 142

 

 

however as stated above, what is wrong with my logic?

 

//CONTROLLER

 

 

function retrieve()
// LOADED WHEN THE FORM IS SUBMITTED
{
$this->load->library('form_validation');
$this->load->library('session');
$this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email');
$this->load->model('user_model', 'um');
$this->load->library('encrypt');
$this->load->helper('url');
$submit = $this->input->post('submit');

if($submit)
// IF THE SUBMIT BUTTON IS SET
{
// START PROCESS TO CREATE $USER VARIABLE THAT HOLDS WHAT THE USER ENTERED IN THE FORM AND THAT CAN GET CHECKED AGAINST THE DB IN THE MODEL
$user = $this->um->validate_retrieve(array('email' => $this->input->post('email')));

// IF THE USER IS CREATED AND CHECKS OUT AND ALL OF THE ERRORS ARE CLEARED ON THE FORM
if( $user && $this->form_validation->run() == TRUE ) {

$domain = "clci.dev/index.php";

// CREATE A TOKEN LINK TO SEND TO THE USERS EMAIL THAT EXIST IN THE DB AND WAS ENTERED
foreach ($query->result() as $user)
$token = sha1($user->email.$user->salt).dechex($user->id);
$link = "http://www.".$domain."/account/confirmation/?token=$token";
{

$this->load->library('email');

$this->email->from('noreply@cysticlife.org', 'CysticLife');
$this->email->to($user->email);

$this->email->subject('Welcome to CysticLife!');
$this->email->message("Thanks for signing up for CysticLife! To complete the registration process please go to the following web address:\n\n$link\n\n-Your friends at CysticLife\n\nPlease remember to add the cysticlife.org domain to your address book to ensure that you receive your CysticLife e-Notifications as requested.eh");

$this->email->send();
redirect('account/welcome');
exit;
}
}
else {
$data['main_content'] = 'auth/password';
$this->load->view('includes/templates/main_page_template', $data);
}
}
}

 

//VIEW

 

 

 

<div id="forget_pw_form">
<div class="forgotten_pw_text">
Please enter your email address to reset password
</div>
<?php
echo validation_errors();
echo form_open('auth/retrieve');
echo form_label('', 'email', array('type'=>'text'));
$data = array( 'name' => 'email', 'class' => 'input', 'placeholder' => 'Email' );
echo form_input($data, set_value('email'));
echo form_submit('submit', 'Submit');
echo form_close();

echo "<span class='errors'>";
echo form_error('email');
echo "</span>";
?>
</div>

 

//MODEL

 

 

function validate_retrieve($data) {

$query = $this->db->where($data)->get('users', '1');

if($query->row())
{
return $query->row();
}

}

A: labeling line #142 would be helpful

 

potentially check your "if" in your model. I think it should be:

if($query->num_rows() > 0)
{
   return $query->row();
}

foreach ($query->result() as $user)
