  • Easier way to populate form data and validation data in Code Igniter?

    - by John
    I'm new to code igniter. I'm following the form validation tutorial found at: http://www.codeignitor.com/user_guide/libraries/validation.html I find I am typing too much in the view to get the form to re-populate. For example, here's what one of my INPUT fields look like: <input type="text" name="email" value="<?=$this->validation->email ? $this->validation->email : $array_db_values['email'] ?>" /> Basically, when the form first loads, it should show a value from the database. If the user alters the value and it fails validation, then the form should post the erroneously submitted value. Does code igniter have a "cleaner" way of rendering this kind of output? Otherwise, I'm going to do something like this in my controller: $array_db_values = getdbresults(); if($_POST['submit']) foreach($_POST as $key=>$val) $array_db_values[$key] = $val; That way, if postback data exists, it will always override database values. Then input fields in my view can simply be: <input type="text" name="email" value="<?=$array_db_values['email'] ?>" /> Is there a better/native CI way to handle this scenario?

  • Zend_Registry: real life examples

    - by takeshin
    Do you find Zend_Registry useful? For which tasks it should be used? For which not? Global state for variables is not a good practice. Main objects may have global state injected via $front->setParam('paramName', $object), so what's the purpose of Zend_Registry?.

  • Shorter GUIDs than hashing a user id?

    - by Alex Mcp
    I'm wondering how Instapaper (bookmarklet that saves text) might generate URLs for their bookmarklet. Mine has a script src of something similar to www.instapaper.com/j/AnJHrfoDTRia The quality of these URLs is that they need to never collide, and not be really guessable (so other people can't save to your account). I know a simple approach might be to MD5 their email address (presumed to have been checked on signup for uniqueness), but then I'd end up with a super long string. This isn't a huge issue, but I'm wondering what techniques there are for shorter GUIDs that won't collide too often (this is obviously the tradeoff, but 12 characters above is pretty short in my opinion)

  • understanding the ORM models in MVC

    - by fayer
    i cant fully understand the ORM models in MVC. so i am using symfony with doctrine. the doctrine models are created. does this mean that i don't have to create any models? are the doctrine models the only models i need? where should i put the code that uses the doctrine models: eg. $phoneIds = array(); $phone1 = new Phonenumber(); $phone1['phonenumber'] = '555 202 7890'; $phone1->save(); $phoneIds[] = $phone1['id']; $phone2 = new Phonenumber(); $phone2['phonenumber'] = '555 100 7890'; $phone2->save(); $phoneIds[] = $phone2['id']; $user = new User(); $user['username'] = 'jwage'; $user['password'] = 'changeme'; $user->save(); $user->link('Phonenumbers', $phoneIds); should this code be in the controller or in another model? and where should i validate these fields (check if it exists in database, that email is email etc)? could someone please shed a light on this. thanks.

  • How can I distribute x cakes amongst y people?

    - by Rupert
    I have an associative array with the ids of x cakes and another associative array with the ids of y people. I want to ensure that each cake is enjoyed by exactly 2 people and that each person gets a fair share of cake overall. However, cakes must be kept whole (i.e. if the average cake per person is a fraction, this fraction will be rounded up for some, and down for others). No person can be assigned the same cake twice. For example: $cake = array('id'=>'1','id'=>'2') $people = array('id'=>'1','id'=>'2','id'=>'3') In order to do so, I wish to create a new array where each row represents a cake-person assignment. As each cake is being assigned to two people, the number of rows in this table should be exactly twice the number of cakes. There will not be exactly 1 solution to this problem but a solution to the above example would be: $cake_person = array( '1'=>array('cake_id'=>'1', 'person_id'=>'1'), '2'=>array('cake_id'=>'1', 'person_id'=>'2'), '3'=>array('cake_id'=>'2', 'person_id'=>'2'), '4'=>array('cake_id'=>'2', 'person_id'=>'3'), ) Notice that people 1 and 3 are losing out but that is because there is no more cake to go around! Each cake must be given exactly twice. How can I generate such a solution reliably for larger numbers of people and cakes?

  • Stay on current page after POST

    - by DogPooOnYourShoe
    I have a form which once the Submit button is pressed, it goes to a blank page and returns any error messages on that blank page. However I have a website template and I wish that my script is run, and returns the the page which did the action POST and puts any error messages on that page. Example of what is happening: PAGE REQUESTS POST ---- SCRIPT RUNS --- RETURNS ERROR MESSAGE What I want it to do is: PAGE REQUESTS POST --- SCRIPT RUNS ---- GOES TO THE PAGE WHICH REQUESTED POST ---- SHOWS ANY ERROR MESSAGES WHICH THE SCRIPT PICKED OUT.

  • Combining array values in multilevel array

    - by James Huckabone
    I have an array like so: array( 'a'=>array( 'a'=>3, 'f'=>5, 'sdf'=>0), 't'=>array( 'a'=>1, 'f'=>2, 'sdf'=>5), 'pps'=>array( 'a'=>1, 'f'=>2, 'sdf'=>3) ); Notice how the sub-arrays are the same for each top-level array. If I wanted to, what's the easiest way to combine the sub-arrays so that I'm left with a one-dimensional array like: array( 'a'=>5, 'f'=>9, 'sdf'=>8 );

  • help with Zend dispatcher

    - by simple
    this is the Zend Controller Dispatcher Standart public function isDispatchable(Zend_Controller_Request_Abstract $request) { $className = $this->getControllerClass($request); echo 'is dispatchanble started'; var_dump($className); if (!$className) { return false; } var_dump(class_exists($className, false)); if (class_exists($className, false)) { return true; } $fileSpec = $this->classToFilename($className); $dispatchDir = $this->getDispatchDirectory(); $test = $dispatchDir . DIRECTORY_SEPARATOR . $fileSpec; return Zend_Loader::isReadable($test); } I need to set up custom modular structure and loading just using plugins (I need to setup the path where zend looks for controller), so I am stuck tracing down I came to the isDispatchable method that returns false and consequently the dispatching returns error . This method returns false because class_exists return false , it is surely has to do with auto loading ,but confused. help will be appreciated,though I got the feeling that I am looking at wrong place.

  • Is there any injection vunerability in the body of an email?

    - by Brett
    Hey guys..... AFAIK there is only a vulnerability within the HEADERS of an email when using user data correct? I am using the below function to sanitize my data, however I have some textarea fields on the page & hence these may contain linebreaks.. so was wondering if that user data is only going to be put in the body of the email, can it not bother with being sanitized - apart from stripping html of course? Here is the function: function is_injected($str) { $injections = array('(\n+)', '(\r+)', '(\t+)', '(%0A+)', '(%0D+)', '(%08+)', '(%09+)' ); $inject = join('|', $injections); $inject = "/$inject/i"; if (preg_match($inject,$str)) { return true; } else { return false; } } As a side note, surprised there wasn't currently a tag for mail-injection / email-injection. Thanks!

  • how are association, aggregation and composition written?

    - by ajsie
    i have read some posts about the differences between these 3 relationships and i think i get the point. i just wonder, are all these written the same when coding? question 1: all 3 are just a value of the object type in a instance variable? class A { public $b = '' public function __construct($object) { $this->b = $object // <-- could be a association, aggregation or a composition relation? } } question 2: does it have to be an instance variable or can it be a static one? class A { public static $b = '' // <-- nothing changed? public function __construct($object) { $this->b = $object } } question 3: is there a difference in where the object is created? i tend to think that composition object is created inside the object: class A { public $b = '' public function __construct() { $this->b = new Object // is created inside the object } } and aggregation/association is passed through a constructor or another method: class A { public $b = '' public function __construct($object) { // passed through a method $this->b = $object } } question 4: why/when is this important to know. do i have to comment an object inside another what relation its about or do you do it in an UML diagram? could someone shed a light on these questions. thanks!
