I'm trying to improve my understanding on OOP^^
If I call this file...
set_organization.php file:
$organization = new Organization( );
$organization->name = 'Name here';
$organization->founder = 'Founder here';
then I access it again, are the name, and founder already set? Or should I put unset to ensure it's empty, like fresh start again? I'm kind of confused whether I need to unset it something like this:
$organization = new Organization( );
$organization->name = 'Name here';
$organization->founder = 'Founder here';
unset($organization);
to avoid query related bugs...please help.
Thanks!
Each time you call new Organization( ); a new instance is created that has nohing to do with any previous ones (except static class members).
If this is done in sepereate requests even more so, but this is because each request runs it's own script.

I'm fixing up some old code that is supposed to create a directory for a customer based on the customer's last name. 999 out of 1000 times it works as expected but every now and then I get an "Unable to create base directory" error message and the debug shows me that the $file_directory in that case is simply "Array" instead of something like "\\network\path\order_data\1234567890_Smith".
Could anyone explain how this code could work the vast majority of the time but still consistently fail about .1% of instances? Or is it something other than the code? Thanks!
Note: I did not originally write this code but am tring to leave it as close to the original as possible
Edit I had a typo in my previous code but I think tliokos and Fluinc had a very good point but just wanted to fix my mistake
Code:
<?php
$file_directory = build_directory($customer, $UID);
if(!is_dir($file_directory)){ //Check to make sure it does not already exist
if(!mkdir($file_directory)){
mail("debug#example.com","Unable to create base directory","$file_directory");
}
}
function build_directory($customer, $UID){
if($customer->related_orders){
$related = explode(",", $customer->related_orders);
foreach($related as $r_UID){
$rel_order = get_order($r_UID); //fetches order object
if((isset($rel_order->file_directory) && $rel_order->file_directory != "")){
return $rel_order->file_directory;
}
}
}
//Here is where I made my correction
$paths = array('\\\\network\\path');
$base = $paths[0];
//Test if directory is already assigned
if(is_dir($base . "\\order_data\\".$UID."_".str_replace(" ","_",$customer->last_name)."\\")){
return $base . "\\order_data\\".$UID."_".str_replace(" ","_",$customer->last_name)."\\";
}
if($base){
return $base . "\\order_data\\".$UID."_".str_replace(" ","_",$customer->last_name)."\\";
}
}
?>
Change $base = array('\\network\path');
To $base = '\\network\path';
I think the problem is in the build_directory() function and more specifically after the first if.
So if the customer has no related orders, you are trying to concatenate an Array with a string and the result is like
Array\order_data\....
Try o change
$base = array('\\network\path');
to
$base = '\\network\path';
So the problem ended up being framework/user related.
We discovered that if the user refreshed the page during the directory creation it would create the same directory twice which our framework would save as an array of identical paths.
I am trying to pull information into a page using my model. The issue is that I need to use an IN condition on my mysql using a variable.
Here is the code I use currently
$list_id = '1,3';
$clients = ListSubscriber::model()->findAll(array('condition'=>'list_id IN (:list_id)','params'=>array(':list_id'=>$list_id)));
I won't necessarily know how many numbers will be stored within $list_id, hence the need for a variable to work with the IN.
The code does execute without errors, but only seems to return the values for the first number of $list_id, so in this case it only finds users where the list_id = 1.
Any help is appreciated. I have found this question Yii addInCondition
However they are using static values, which does not resolve my issue.
When I do use static values, the code executes with results as expected.
You can use addInCondition :
$list_id = '1,3';
$criteria = new CDbCriteria();
$arr_list_id = explode(",",$list_id);
$criteria->addInCondition("list_id ", $arr_list_id );
$clients = ListSubscriber::model()->findAll($criteria);
$list_ids = array(1,3);
$clients = ListSubscriber::model()->findAllByAttributes(array('list_id'=>$list_ids));
I have a custom component, in fact several. Each will have raw and hard-coded html at the beginning and end of their /view/default.php
I have a system plugin that needs to get this html and in some cases change it to something else, that can be managed in the back end. As a content plugin this works fine on all com_content articles, but it is ignored by components, my understanding is system plugins can do this but i can't get the data into the plugin and return it
example of component text ($text1, $text2 are defined at the top of the document)
JPluginHelper::importPlugin( 'system' );
JPluginHelper::importPlugin('plgSystemMyplugin');
$dispatcher =& JDispatcher::getInstance();
$data = array($text1, $text2); // any number of arguments you want
$data = $dispatcher->trigger('onBeforeRender', $data);
<article>
<div class="spacer" style="height:25px;"></div>
<div class="page_title_text">
<h1>title</h1>
<?php var_dump($data); ?>
</div>
<section>
my plugin:
jimport( 'joomla.plugin.plugin' );
class plgSystemMyplugin extends JPlugin {
function onBeforeRender() {
if (JFactory::getDocument()->getType() != 'html') {
return;
}
else {
$document=JFactory::getDocument();
$document->addCustomTag('<!-- System Plugin has been included (for testing) -->');
$document=JResponse::getBody();
$bob=JResponse::getBody();
$db = &JFactory::getDbo();
$db->setQuery('SELECT 1, 2 FROM #__table');
$results = $db->loadRowList();
$numrows=count($results);
if($numrows >0) {
foreach($results as $regexes) {
$document = str_replace($regexes[0],$regexes[1],$document);
}
return $document;
}
else {
$document = 'error with plugin';
}
JResponse::setBody($document);
return $document;
}
}
}
at the moment $data returns an array with a key 1 and value (string) of "" (blank/empty).
but not the data from the database I am expecting.
in simple terms I have {sometext} in my file and my database and it should return <p>my other text</p>
can you help?
thanks
Ok. Well looking at this deeper there is a couple of issues that jump out. The biggest being that you save getBody into a variable named $bob but then switch everywhere to using $document which is the object form above, not the content.
Also, you had a return $document hanging out in the middle of the code that prevented you from seeing that you were going to set $document as the new body. Probably should be more like below:
$bob=JResponse::getBody();
$db = &JFactory::getDbo();
$db->setQuery('SELECT 1, 2 FROM #__table');
$results = $db->loadRowList();
$numrows=count($results);
if($numrows >0) {
foreach($results as $regexes) {
$bob = str_replace($regexes[0],$regexes[1],$bob);
}
}
else {
$bob = 'error with plugin';
}
JResponse::setBody($bob);
return $document;
}
Original Thoughts:
Two thoughts to get you started. I'm not sure that this will actually fully answer the question, but should get you moving in the right direction.
First, you should not have to trigger the system plugin. They are system plugins, so the system will take care of that for you. If you wanted to use content plugins in your component (which you can definitely do!) then you would have to trigger them like your first set of code. In this case, don't bother with the entire dispatch section.
Second, your plugin looks set up to grab the body from the JDocument correctly, so that should work.
The likely issue is that the entire system plugin is just not being triggered. Make sure that it is installed and everything is named correctly. It has to be at plugins/system/myplugin/myplugin.php based on this name and make sure that the xml file with this also references myplugin as the plugin name. If not, the system won't find the class but likely won't throw an error. It will just skip it. This gives me trouble every time.
To do some checking just to make sure it gets called, I usually throw an echo or var_dump near the top of the file and just inside the function. Confirm that the function is at least getting called first and you should be most of the way to getting this to work.
In my code i am trying to store a variable between two pages but i either get a string return "images" or 0... or nothing- tried casting it.. echoing in on one page works and displays correct number but as soon as you click through the view to the next page- its lost- i tried turning on cs_sessions in the db and made no difference
<?php
public function carconfirm($car_id = '')
{
if(empty($car_id))
{
redirect('welcome');
}
$this->load->model('mcars');
$car = $this->mcars->getCar($car_id);
$data['car'] = $car->row_array();
$car_id = (int) $car_id;
$this->session->set_userdata('flappy', $car_id);
echo $car_id;
//insert details
//display details
$this->load->view('phps/carconfirm',$data);
}
function confirm()
{
//get vars
$time_slot = $this->session->userdata('slot');
$person_id = $this->session->userdata('person_id');
$car_id = $this->session->userdata('flappy');
$insert_array = array( 'slot'=> $time_slot ,
'car'=> $car_id,
'person_id'=> $person_id
);
print_r($insert_array);
$this->load->model('mbooking');
$result = $this->mbooking->addbooking($insert_array);
if($result)
{
redirect('welcome/options');
}
}
?>
the variable I'm losing is flappy- i changed the name to see if that was the problem
Finally, I fixed this. Using this answer in SO too : codeigniter setting session variable with a variable not working, I scan my js/css for missing resources. Turn out that, my thickbox.js refer to loadingAnimation.gif in, yes, images folder. That's where the images come. Having fix the missing file, the sesion variabel working just fine.
Not sure, why CI replace (maybe) last added session variabel using this, but maybe it's because CI is not using $_SESSION global variabel. CMIIW. I use this article as a hint : http://outraider.com/frameworks/why-your-session-variables-fail-in-codeigniter-how-to-fix-them/
I've posted this in the CodeIgniter forum and exhausted the forum search engine as well, so apologies if cross-posting is frowned upon.
Essentially, I've got a single input, set up as <input type="text" name="goal">. At a user's request, they may add another goal, which throws a duplicate to the DOM. What I need to do is grab these values in my CodeIgniter controller and store them in a session variable. My controller is currently constructed thusly:
function goalsAdd(){
$meeting_title = $this->input->post('topic');
$meeting_hours = $this->input->post('hours');
$meeting_minutes = $this->input->post('minutes');
$meeting_goals = $this->input->post('goal');
$meeting_time = $meeting_hours . ":" . $meeting_minutes;
$sessionData = array(
'totaltime' => $meeting_time,
'title' => $meeting_title,
'goals' => $meeting_goals
);
$this->session->set_userdata($sessionData);
$this->load->view('test', $sessionData);
}
Currently, obviously, my controller gets the value of each input, writing over previous values in its wake, leaving only a string of the final value. I need to store these, however, so I can print them on a subsequent page.
What I imagine I'd love to do is extend the input class to be able to call $this->input->posts('goal'). Eventually I will need to store other arrays to session values. But I'm totally open to implementation suggestion.
Thanks so much for any help you can give.
You'd want to use this in your form:
<input type="text" name="goal[]">
You can then get the values in the Controller via:
$goal = $this->input->post('goal');
And then set the variable in the session via:
$this->session->set_userdata('goal', $goal);
If you want to retrieve it again. do this via:
$goal = $this->session->userdata('goal');
You'll have something like this:
$goal[0] = 'first goal';
$goal[1] = 'second goal';
Please try it first :)
