Codeigniter - Undefined Variable: Config. Error But Email Is Sent?

Apr 5, 2011

I just downloaded version 2.0.1 of CodeIgniter framework and I am attempting to write my own email controller like so:

<?php

class Email extends CI_Controller
{
function __construct() { parent::__construct(); }[code]....

In spite of the PHP error, email is being sent fine, with a file attachment.How can I remove this PHP error? What am I doing wrong?

CodeIgniter - Accessing $config Variable In View?

Apr 13, 2010

Pretty often I need to access config variables in views. I know I can pass them from controller to load->view(). But it seems excessive to do it explicitly.

Is there some way or trick to access $config variable from CI views without disturbing controllers with spare code?

CodeIgniter - Weird Echo Of $config Coming Back When Load Email Library

Apr 27, 2010

Version info: CI version 1.7.2 - PHP 5.3.1 - Apache2 - Mac OSX 10.6.3

For some reason, when I load CI's email library, either in my controller, or in autoload.php, it automatically and immediately echoes the config info like so:

$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE

If I autoload the email library in autoload.php, it is echoed before anything else in my source/page. If I call it explicitly within my controller, it's echoed at that exact point.

Codeigniter: Access Config Variables From Other Config Files?

Dec 9, 2010

I have two config files.

config.php (code igniters core config)

and email.php (autoloaded by the email class when it is used)

What i am wanting to do is.

In config.php have

$config['env'] = 'hailwood_dev';

then in email.php have

if($config['env'] == 'hailwood_dev'){
//email variables like smtp server to do with localhost
} elseif($config['env'] == 'production'){
//email variables like smtp server to do with production
}

But this is not having any effect (im guessing as $config['env'] does not have those values).

How can I access this value?

CodeIgniter 'Undefined Variable'?

Apr 19, 2010

This is probably an easy one but I barely got any sleep last night and am struggling to comprehend anything.I've got a CodeIgniter library I've made called Points.php. Here's the contents of Points:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
class Points
{[code]....

As you can see, I'm building it up slowly and it's being kept simple.In one of my views, I want it to display the number of 'points' (which for the time being is simply the third segment of the URI). I call it like this:

<p>Points: <?php $params['user_id']=$this->uri->segment(3,1); echo $this->points->getpoints($params); ?></p>

The warning I get back in the view is this:

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: userid

Filename: libraries/Points.php

Yes I know it's such a simple problem but I've tried lots of things. Some variations include echoing in Points.php $params['userid']; etc. But I don't see what I'm doing wrong?

Undefined Index Error In Email Form

Can anyone help a newbie understand how a 'send email form' works? Want to have the form send the data to itself and validate the data before displaying a confirmation page. Seems easy enough.

The system gives an 'undefined index' error when the code tries to access the POST array eg. $test=$_POST['submit']; Have tried $_POST['submit'], $HTTP_POST_VARS['submit'], have checked whether the arrays are empty (they are) have tried global_variables on and off.

Rookie, Receiving An Undefined Variable Error?

Jan 25, 2011

I am reading a book and going through the examples, unfortunately i keep getting an error if i leave a field empty when i submit the form. I checked the errata and there was nothing, i tried posting on the books forums but I didn't get any responses.

I believe that maybe i have to declare the variables first but that would take away from the variables being automatically generated.

$expected = array('name', 'email', 'comments');
$required = array('name', 'email', 'comments');
<?php
foreach ($_POST as $key => $value){
//assign to temporary variable and strip whitespace if not an array
$temp = is_array($value) ? $value : trim($value);
//if empty and required, add to $missing array
if (empty($temp) && in_array($key, $required)){
$missing[] = $key;
} elseif(in_array($key, $expected)){
//otherwise, assign to a variable of the same name as $key
${$key} = $temp;
}
}
<?php
include('./includes/title.inc.php');
$errors = array();
$missing = array();
//Check to see if the form has been submitted
if (isset($_POST['send'])){
//email processing script
$to = 'drewdin1@hotmail.com'; //use your email address
$subject = 'Feedback from Japan Journey';

Global Access Of Vars - Error Message - Undefined Variable

This is file index.php that 'requires' myGlobals.php then calls a function in a 3rd php file

My second problem is that if someone dechecks the selections (which shouldn't happen), the correct error is applied, but then I get the "Notice: Undefined variable: membership in line 100" obviously caused by a checkbox option is not set.

How do I set the default checkbox? and how do I prefent the 'Undefined' error if someone decides to decheck the selections?

Codeigniter Add Exceptions To Config Class

Feb 23, 2010

Maybe, it's a bit silly, but does anybody thought about adding exceptions to Codeigniter Config Class(Library). Not sure, it is(will be) a good practice, but i suppose throwing an exception instead of just returning false is better. For example, if we have something connected with user payments. Usually(?), we'll take some configurable data from codeigniter config files. Imagine, we've done a typical error specifying config index, and CI will return just false, which may cause some logic(!not syntax) error in this software.

Write An Array To Config In Codeigniter?

Aug 1, 2010

I'm working with a config file that I have create in order to store users. This surely wasn't what the configs were intended to be used for, but it's an extremely small application and I think that it would be a nice solution.

My array looks like this:

$config['users'] = array(array('username' => 'username', 'password' => 'password'));

This works well. I can retrieve the information quick and easy. BUT, if I try to write a new array (a new user) to the config file I get this error:
Illegal offset type in isset or empty

I'm using $this->config->item('users', array('username' =>....)) which doesn't appear to support arrays.

How can I write arrays to my config variable? Is there another way? I was so sure in my head that I could use config->item() that I didn't check the manual for a config->set_item()... BUT, it still doesn't work. Here is the specific code:

$users = $this->config->item('users');
array_push($users, array('username' => $this->input->post('username'), 'password' => $this->input->post('password')));
$this->config->set_item('users', json_encode($users));
echo json_encode($users);

This code is called via Ajax, and I have an alert box to see if it the values are correct. They are. And as you can see, I've tried storing it as json instead of array as well...

Codeigniter Return Config File As Array With Autoload Enabled?

May 28, 2010

So I'm using CodeIgniter to build a website and I've made it so that all my specific settings are stored in a config file that's automatically loaded. I've also built a page that loads the settings file, makes a nice little table and allows me to edit everything from that page, afterwards it saves the entire page again (I know I could've done the same with a database but I want to try it this way).

My problem is that I can't seem to use this bit when autoloading of my config file is enabled, but when I disable autoloading I can't seem to manually load it, it never finds my variables. So what I'm doing here is just taking all values from the config file and putting them in a single array so I can pass this array onto my settings administration page (edit/show all settings).

$this->config->load('site_settings', TRUE);
$data['settings'] = $this->config->item('site_settings');
...
$this->load->view('template', $data);
config/site_settings.php

Referencing A Local Variable In A Global Variable Defined In A Config.inc File?

Apr 26, 2009

I use a conf.inc.php to define some Global variables since I roll out several copies of the same code over and over and need an easy place to edit some basic string variables. My question is if someone knows how to reference a local variable (local to where the Global is called) in the Global variable.

simplified example of what works:

conf.inc.php file:
$GLOBALS['favcolor'] = "My favorite color is %s.";
Some other php file where I call that Global:
include_once("../conf.inc.php");

[code]....

In the above example I would much prefer defining the Global variable in conf.inc.php as:

$GLOBALS['favcolor'] = "My favorite color is $color.";

but this of course references a local variable in conf.inc.php named $color not in the second PHP file where the Global is called. What is the syntax in the Global declaration so that the variable $color references the local variable in the second php file?

} elseif ($_GET['module'] == 'module') {
    Do this.

"Call To Undefined Method" Error When Calling Invoke From Class Variable

Jun 24, 2010

I have been doing some tests (to replace old code) with the __invoke magic method and I'm not sure this is a bug or not:

Lets suppose we have a class:

class Calc {
function __invoke($a,$b){
return $a*$b;
}

[Code].....

The error occurs when we try to call it like:

$t = new Test;
echo $t->k(4,5); //Error: Call to undefined method Test::k()

I know that a "solution" could be to have a function inside the class Test (named k) to "forward" the call using call_user_func_array but that is not elegant.

I need to keep that instance inside a common class (for design purposes) and be able to call it as function from other classes..

Update:

I found something interesting (at least for my purposes):

If we assign the "class variable" into a local variable it works:

$t = new Test;
$m = $t->k;
echo $m(4,5);
