  • Open source web cam conference software

    - by BasicallyBoredWithoutAnOffice
    Quick question, has anyone ever come across either a web cam API or an open source alternative that can be easily integrated to a site without having any Flash or ActionScript experience. I should probably say what I'm trying to do.... The idea is to create a Facebook app that lets friends communicate (and meet new people too) in real time over web cam. However I don't have the required experience to write the Flash part so any help would be appreciated.

  • How to create wordpress-like option table and get values for each row?

    - by Nacho
    Hi guys. I'm looking to create an options table in my db that makes every record a system option, so I can work with a little number of fields. My db has the following structure: 3 columns named id, name, and value The following data is inserted as an example: +--+-----------+--------------------------+ |id|name |value | +--+-----------+--------------------------+ | 1|uri |www.example.com | | 2|sitename |Working it out | | 3|base_folder|/folder1/folder2/ | | 4|slogan |Just a slogan for the site| +--+-----------+--------------------------+ That way I can include a large number of customizable system options very easily. The problem is that I don't know how to retrieve them. How do I get the value of uri and store it as a var? And better yet, how do I get, for exmaple, values of id 1 and 4 only without making a query each time? (I assume multiple queries are useless and a pretty ugly method.) I know the question is pretty basic but I'm lost here. I'd really appreciate your answer!

  • Setting ownership/permissions for symfony2 and other web projects

    - by Handonam
    I've been very confused as to how to set permissions and user/groups for my sites. It is particularly one of my weakest suits My curent problem is that I often find myself running into a situation where if i view a particular page, it won't have permissions to write to cache or logs. At this point I'll set the ownership towards apache. Then, in other cases, if i try to run internal scripts, for example, I can't write to these cache/log files because i set them for apache. Currently, my symfony2 files are all registered to me as a part of staff (Handonam:Staff). I've seen various people creating groups such as www-data, apache, etc, and using users such as theirselves (e.g. Handonam) or www as a part of those groups. So my question is: For symfony2 and other web projects, what's generally the best setup for user/group setup so that both apache and myself can interact with these files, while maintaining decent security?

  • Is it necessary to mysql real escape when using alter table?

    - by cgwebprojects
    I noticed the other day that I cannot bind variables when using PDO with ALTER TABLE for example the following example will not work, $q = $dbc -> prepare("ALTER TABLE emblems ADD ? TINYINT(1) UNSIGNED NOT NULL DEFAULT '0', ADD ? DATETIME NOT NULL"); $q -> execute(array($emblemDB, $emblemDB . 'Date')); So is it necessary to use mysql_real_escape string and do it like below, // ESCAPE NAME FOR MYSQL INSERTION $emblemDB = mysql_real_escape_string($emblemDB); // INSERT EMBLEM DETAILS INTO DATABASE $q = $dbc -> prepare("ALTER TABLE emblems ADD " . $emblemDB . " TINYINT(1) UNSIGNED NOT NULL DEFAULT '0', ADD " . $emblemDB . "Date DATETIME NOT NULL"); $q -> execute(); Or do I not need to add in mysql_real_escape_string? As the only thing the query can do is ADD columns? Thanks

  • How can one describe a rock-paper-scissors relationship between 3 items?

    - by Madara Uchiha
    Let's say I have the following structure: abstract class Hand {} class Rock extends Hand {} class Paper extends Hand {} class Scissors extends Hand {} The goal is to make a function (or a method) Hand::compareHands(Hand $hand1, Hand $hand2), which would return the winning hand in a rock-paper-scissors match. That would be very easy with a bunch of ifs, but the point is to have a more robust structure, that's relying on polymorphism rather than on procedural code. P.S. this is done in actual production code, if someone is asking. This isn't some sort of challenge or homework. (It's not really rock-paper-scissors, but you get the point).

  • One regular expression to match parts in various positions

    - by richsage
    Hi all, I'm trying to parse a DSN (from a Symfony application) using regular expressions, in order to link with a secondary application, but using the same database. The DSN I currently have is: mysql:dbname=my_db_name;host=localhost with a regex of: /^(\w+):(dbname=(\w+))?;?(host=(\w+))?/ (using preg_match()). This matches OK, but fails in my test environment because the DSN elements are switched around, thus: mysql:host=localhost;dbname=my_testdb_name I could just switch them round, yes :-) but I'm sure that extraction of the host and dbname parts from both DSNs is possible with a single regular expression, and I'd like to be able to enhance my knowledge at the same time ;-) Is there a way I can do this?

  • Size SKU in Magento

    - by latvian
    Hi, How can I allow SKU be longer than 34 characters (for simple products) for all products? When i add new product(simple) and enter more than 34 characters, Magento cuts it to 34 after saving. In the database the 'sku' attributes ( for quete item,order item,invoice item, shipment item) from eav_attribute table hold varchar(255). For Catalog_Product_Entity the attributed is VarChar(64). In either case, it is more than 34characters. Thus, I could change SKU to 64 characters without making any change in database, correct? How do i do that? I have good understanding of the user side magento code, but not Admin side. Can you suggest me good tutorial on making changes in Admin side that could help me figure this question myself. Thank you, Margots

  • How does Symfony pass members set in an action to a template?

    - by Martin Chatterton
    How does a member set inside an action... $this->foo = 'bar'; ...become a variable accessible from a template... echo $foo; // bar I would like to know how it is achieved at a framework level. There is a lot of documentation on how to use Symfony, but I've not managed to find much about how it all fits together behind the scenes (class structure/inheritance etc). Thanks in advance for your help!

    - by fayer
    i wonder if there are tutorials/books explaining how you create a library/plugin/module for other to implement? libraries/frameworks like solr, doctrine, codeigniter etc. cause it seems that they follow the same pattern. having one "bootstrap" file to load configurations, other classes and so on. i aim to understand the basics, so i can create a such library. cause at the moment i want to code an address book that other can use. just include a bootstrap file and they are ready to use my classes (like Doctrine). recommendations of sources to learn these things of stuff? you experienced guys, how did you learn it? thanks.

  • Short snippet summarizing a webpage?

    - by Legend
    Is there a clean way of grabbing the first few lines of a given link that summarizes that link? I have seen this being done in some online bookmarking applications but have no clue on how they were implemented. For instance, if I give this link, I should be able to get a summary which is roughly like: I'll admit it, I was intimidated by MapReduce. I'd tried to read explanations of it, but even the wonderful Joel Spolsky left me scratching my head. So I plowed ahead trying to build decent pipelines to process massive amounts of data Nothing complex at first sight but grabbing these is the challenging part. Just the first few lines of the actual post should be fine. Should I just use a raw approach of grabbing the entire html and parsing the meta tags or something fancy like that (which obviously and unfortunately is not generalizable to every link out there) or is there a smarter way to achieve this? Any suggestions? Update: I just found InstaPaper do this but am not sure if it is getting the information from RSS feeds or some other way.

  • How do large sites accomplish row-level permissions?

    - by JayD3e
    So I am making a small site using cakephp, and my ACL is set up so that every time a piece of content is created, an ACL rule is created to link the owner of the piece of content to the actual content. This allows each owner to edit/delete their own content. This method just seems so inefficient, because there is an equivalent amount of ACL rules as content in the database. I was curious, how do big sites, with millions of pieces of content, solve this problem?

  • Surely a foolish error, but I can't see it

    - by dnagirl
    I have a form (greatly simplified): <form action='http://example.com/' method='post' name='event_form'> <input type='text' name='foo' value='3'/> <input type='submit' name='event_submit' value='Edit'/> </form> And I have a class "EventForm" to process the form. The main method, process() looks like this: public function process($submitname=false){ $success=false; if ($submitname && isset($_POST[$submitname])){ //PROBLEM: isset($_POST[$submitname] is always FALSE for some reason if($success=$this->ruler->validate()){//check that dependancies are honoured and data types are correct if($success=$this->map_fields()){//divide input data into Event, Schedule_Element and Temporal_Expression(s) $success=$this->eventholder->save(); } } } else {//get the record from the db based on event_id or schedule_element_id foreach($this->gets as $var){//list of acceptable $_GET keys if(isset($_GET[$var])){ if($success= $this->__set($var,$_GET[$var])) break; } } } $this->action=(empty($this->eventholder->event_id))? ADD : EDIT; return $success; } When the form is submitted, this happens: $form->process('event_submit'); For some reason though, isset($_POST['event_submit']) always evaluates to FALSE. Can anyone see why?

  • print friendly version of floated list

    - by Brad
    I have a list of phone extensions that I want to print a friendly version of it. I have a print css for it to print appropriately onto paper, the extensions are located within an unordered list, which are floated to the left. <ul> <li>Larry Hughes <span class="ext">8291</span></li> <li>Chuck Davis <span class="ext">3141</span></li> <li>Kevin Skillis <span class="ext">5115</span></li> </ul> I float it left, and when it prints the second page, it leaves off the name part of the list (in Firefox, works fine in Google Chrome and IE), see here: http://cl.ly/de965aea63f66c13ba32 I am referring to this: http://www.alistapart.com/articles/goingtoprint/ - they mentioned something about applying a float:none; to the content part of the page. If I do that, how should I go about making the list show up in 4 columns? It is a dynamic list, pulled from a database. Any help is appreciated.

  • Saving tags into a database table in CakePHP

    - by Cameron
    I have the following setup for my CakePHP app: Posts id title content Topics id title Topic_Posts id topic_id post_id So basically I have a table of Topics (tags) that are all unique and have an id. And then they can be attached to post using the Topic_Posts join table. When a user creates a new post they will fill in the topics by typing them in to a textarea separated by a comma which will then save these into the Topics table if they do not already exist and then save the references into the Topic_posts table. I have the models set up like so: Post model: class Post extends AppModel { public $name = 'Post'; public $hasAndBelongsToMany = array( 'Topic' => array('with' => 'TopicPost') ); } Topic model: class Topic extends AppModel { public $hasMany = array( 'TopicPost' ); } TopicPost model: class TopicPost extends AppModel { public $belongsTo = array( 'Topic', 'Post' ); } And for the New post method I have this so far: public function add() { if ($this->request->is('post')) { //$this->Post->create(); if ($this->Post->saveAll($this->request->data)) { // Redirect the user to the newly created post (pass the slug for performance) $this->redirect(array('controller'=>'posts','action'=>'view','id'=>$this->Post->id)); } else { $this->Session->setFlash('Server broke!'); } } } As you can see I have used saveAll but how do I go about dealing with the Topic data?

  • Facebook page linking to external site sign-up process, capture permission to write to wall in process?

    - by steve
    Hi all, Have had a good hunt through the archive but can't find anyone trying to do this... hope someone familiar with the facebook API can confirm if it's possible? Basically I have a client who wants to replicate their membership sign up process in a tab on their facebook page. The form would still submit to their own website to process, we'd just be replicating the form fields. As an additional requirement they want to capture peoples facebook user ID and get permission to post back to a users wall at the same time... The idea being that once the user is a member we can post back to their wall so their friends see that they've signed up... Basically after a sanity check that: 1) these things are possible to do; 2) the best method to build the form in a FB page - I'm guessing using JS to create all fields & ajax to submit to the external site? Thanks Steve
