  • if `int != 1` or `int == 0`?

    - by Emil
    Hey. I was coding here the other day, writing a couple of if statements with ints that are always either zero or one (~bools), and I asked myself: Should I use if (int == 1) or if (int != 0) ? Is there any difference at all? Please, don't answer with stuff regarding the int may being more/less than 1/0, that's not what I want to know.

  • How to handle redirections with codeigniter?

    - by SinneR
    Hi, im having problems starting a codeigniter project, the problem is that when i do something in a controller and then i want a page to display the result, an example: i have a form to add a item to the database, i get all the data in the controller and save it to database and then i want (if all went well) to redirect to the main page with a success msg, i was doing this with $this->load->view('admin', $data); the problem is that the url keeps saying admin/addItem so everytime the page gets refreshed it adds another item, now i found the: redirect('admin','refresh'); but this only helps me when i dont need to display any msg because this function dont allow to send a $data var. Any ideas? Probably this is really easy to fix but i cant find a way to handle the flow of the application the way i want, any help is apreciated. thanks ;)

    - by fayer
    i've got a variable $user that is of data type User (a class). i've got it in a class method so i can't just type: /** * @var User */ $user = Factory::getInstance('User'); because that will work only with class properties, not method variables like in this case. how could i tell netbeans that that variable is of data type User in a method?

  • [ZF] How to use Zend_Db without SQL Queries?

    - by rasouza
    The last time I worked with Zend_Db I recall I used to write SQL Queries manually. I've been searching for some ORM application, but, since I read something like Zend_Db is also capable of doing so, I started to try it, but I can't find neither a good tutorial explain it or a good documentation. I read something lake Gateway pattern and ModelMapper class but I can't figure it out. Can someone shine my path? :P

  • I having a problem with the mysqli free() member function

    - by neo skosana
    Hi I have code where I connected to the database like so: $db = new mysqli("localhost", "user", "pass", "company"); Now when I query the database like so: //query calls to a stored procedure 'user_info' $result = $db->query("CALL user_info('$instruc', 'c_register', '$eml', '$pass', '')"); //I use the $result This query works well. Now when I try and free that result like so: $result->free(); or $result->close(); It seems like it doesn't do anything because $result is still set. When I try to run another query it gives me this error: Fatal error: Call to a member function fetch_array() on a non-object in... For me to run this other query I have to close the db conection and connect again, then it will work. I want to know if there is a way I could run the other query without having to disconnect and reconnect to the database. thanks in advance.

  • Add the categories selector widget to the PAGE editor with predefined categories listed?

    - by Scott B
    The following code will add the categories selector widget to the WordPress Page editor interface... add_action('admin_menu', 'my_post_categories_meta_box'); function my_post_categories_meta_box() { add_meta_box('categorydiv', __('Categories'), 'post_categories_meta_box', 'page', 'side', 'core'); } What I would like to do is to figure out how to modify the resulting category listing so that it only contains a predefined list of hard coded categories that I define. Since I'm adding this via my custom theme, it will only appear on the page editor when my theme is active on the site. And I have some specific "handler" categories that my theme installs into the site and later uses to determine layout elements.

  • Checking array of censored words against user submitted content

    - by steve-o
    Hello, I have set up an array of censored words and I want to check that a user submitted comment doesn't contain any of these words. What is the most efficient way of doing this? All I've come up with so far is splitting the string into an array of words and checking it against the array of censored words, but I've a feeling there's a neater way of doing this.

  • What does the $1$2$4 mean in this preg_replace?

    - by Taylor
    Got this function for ammending the query string and was wondering what the replacement part of the pre_replace meant (ie- $1$2$4). function add_querystring_var($url, $key, $value) { $url = preg_replace('/(.*)(\?|&)' . $key . '=[^&]+?(&)(.*)/i', '$1$2$4', $url . '&'); $url = substr($url, 0, -1); if (strpos($url, '?') === false) { return ($url . '?' . $key . '=' . $value); } else { return ($url . '&' . $key . '=' . $value); } } Not too familiar with regular expression stuff. I get the various parts to preg_replace but not 100% about the use of '$1$2$4' in the replacement part.

  • What statistics app should I use for my website?

    - by Camran
    I have my own server (with root access). I need statistics of users who visit my website etc etc... I have looked at an app called Webalyzer... Is this a good choice? I run apache2 on a Ubuntu 9 system... If you know of any good statistics apps for servers please let me know. And a follow-up question: All statistics are saved in log-files right? So how large would these log-files become then? Possibility to split them would be good, dont know if this is possible with Webalyzer though...

  • How can I write this in a shorter way?

    - by oaziz
    This code repeats itself. How can I make it shorter? Maybe by using anonymous function or something? foreach ($value as $wrong) { if (starts_with($wrong, '%') and ends_with($wrong, '%')) { $wrong = trim($wrong, '%'); if (contains($address, $wrong)) { $corrected_address = str_replace($wrong, $key, $address); break; } } else { $wrong = trim($wrong, '%'); if (ends_with($address, $wrong)) { $corrected_address = str_replace($wrong, $key, $address); break; } } } Thanks.
