• chmod 700 and htaccess deny from all enough?

  - by John Jenkins

  I would like to protect a public directory from public view. None of the files will ever be viewed online. I chmoded the directory to 700 and created an htaccess file that has "deny from all" inside it. Is this enough security or can a hacker still gain access to the files? I know some people will say that hackers can get into anything, but I just want to make sure that there isn't anything else I can do to make it harder to hack. Reply: I am asking if chmod 700 and deny from all is enough security alone to prevent hackers from getting my files. Thanks.

• Codeigniter Controller function in a view [closed]

  - by Y2ok

  I'm using CodeIgniter and I have two controllers: Index controller that loads the website view Personal panel controller that will do all login, registration and personal panel functions. (Functions are loaded from models.) The problem is that I don't have any clue how to insert that controller in a view file or in the other controller file so that it would load when I press submit button for a form or if the session's loggedin is with value true.

• On-line Based Conferencing For Admin Panel

  - by Tim Marshall

  Working on my admin panels work station section which will allow the admin to use simple office tools such as word editors, calculators and whatnot. Under this section of the admin panel, I would like to add a conferencing feature which will allow any administrator to connect with another administrator 1-2-1 under the 1-2-1 Conferencing section, or to join a meeting under 'live meeting' section. Upon my search for on-line based, I found there are all these, what seem to be great applications out there, however not all of them are on-line based, and come with a price! I would like to a purely on-line based conferencing/meeting/1-2-1 feature which will allow administrators to communicate via text or sound, stream their video, share their screen and sending of files. I know this sounds like a big feature, and I am not asking for someone to answer by programming one for my website! Does anyone know my best solution to progress to having this feature on my website, any tutorials or free to use, free to modify web plugins? Thank you for your help, Best Regards, Tim

  I, for the life of me, cannot find any literature on this, simply because I have no clue how it is called.

This is what I am talking about Can you please give me some information about how this payment method is called and possibly some articles I can read up on. Thank you!

• unable to send mail from postfix on Ubuntu 12.04

  - by gilmad

  I'm trying to send an email through Google from my localhost. (via PHP5.3) But Google keeps on blocking my requests. I tried to follow the solutions given to a few similar questions, but for some reason they do not work. I followed these instructions to configure it - http://www.dnsexit.com/support/mailrelay/postfix.html Now for the config data: my main.cf file looks like that: relayhost = [smtp.gmail.com]:587 smtp_fallback_relay = [relay.google.com] smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = my sasl_passwd looks like that: [smtp.gmail.com]:587 [email protected]:password and that is how the mail.log rows look like: Dec 14 10:24:50 COMP-NAME postfix/pickup[5185]: 1C3987E0EDD: uid=33 from= Dec 14 10:24:50 COMP-NAME postfix/cleanup[5499]: 1C3987E0EDD: message-id=<[email protected] Dec 14 10:24:50 COMP-NAME postfix/qmgr[5186]: 1C3987E0EDD: from=, size=483, nrcpt=1 (queue active) Dec 14 10:24:50 COMP-NAME postfix/smtp[5501]: 1C3987E0EDD: to=, relay=smtp.gmail.com[173.194.70.109]:587, delay=0.61, delays=0.19/0/0.32/0.1, dsn=5.7.0, status=bounced (host smtp.gmail.com[173.194.70.109] said: 530 5.7.0 Must issue a STARTTLS command first. w3sm8024250eel.17 (in reply to MAIL FROM command)) Dec 14 10:24:50 COMP-NAME postfix/cleanup[5499]: C20677E0EDE: message-id=<[email protected] Dec 14 10:24:50 COMP-NAME postfix/bounce[5502]: 1C3987E0EDD: sender non-delivery notification: C20677E0EDE Dec 14 10:24:50 COMP-NAME postfix/qmgr[5186]: C20677E0EDE: from=<, size=2532, nrcpt=1 (queue active) Dec 14 10:24:50 COMP-NAME postfix/qmgr[5186]: 1C3987E0EDD: removed

• What type of pattern would be used in this case

  - by Admiral Kunkka

  I want to know how to tackle this type of scenario. We are building a person's background, from scratch, and I want to know, conceptually, how to proceed with a secure object pattern in both design and execution... I've been reading on Factory patterns, Model-View-Controller types, Dependency injection, Singleton approaches... and I can't seem to grasp or 'fit' these types of designs decisions into what I'm trying to do.. First and foremost, I started with having a big jack-of-all-trades class, then I read some more, and some tips were to make sure your classes only have a single purpose.. which makes sense and I started breaking down certain things into other classes. Okay, cool. Now I'm looking at dependency injection and kind of didn't really know what's going on. Example/insight of what kind of heirarchy I need to accomplish... class Person needs to access and build from a multitude of different classes. class Culture needs to access a sub-class for culture benefits class Social needs to access class Culture, and other sub-classes class Birth needs to access Social, Culture, and other sub-classes class Childhood/Adolescence/Adulthood need to access everything. Also, depending on different rolls, this class heirarchy needs to create multiple people as well, such as Family, and their backgrounds using some, if not all, of these same classes. Think of it as a people generator, all random, with backgrounds and things that happen to them. Ageing, death of loved ones, military careers, e.t.c. Most of the generation is done randomly, making calls to a mt_rand function to pick from most of the selections inside the classes, guaranteeing the data to be absolutely random. I have most of the bulk-data down, and was looking for some insight from fellow programmers, what do you think?

• Handling array passed to object at creation

  - by cecilli0n

  When creating my object I pass it an array of a row from my database. (everything in the array we will need, disregarding unnecessary elements at sql query level) When I need to access certain array elements from within my class, I do so like $this->row['element'] However, As I continue development, I sometimes forget what exactly is in this passed array.(this itself doesn't seem good) I am wondering if their is a professional approach to dealing with this, Or am I the only one who has these "I wonder whats in the array" thoughts. One approach to tackling this could be that when we originally pass the array, in the constructor, we assign each element of the array to its own variable, but is this considered professional practice? Additionally by doing this, we could make those variables constants, in a attempt at immutability. Overall I am trying to adhere to good software craftsmanship. Regards.

• Fitting an established site into a CI framework

  - by David

  I manage a rather large, feature full nightmare of a site which has no end of feature creep settings/options/etc. Up to now its been coded in a procedural/functional way and would like to move to an OO,MVC setup. I'm quite new to it all but have done alot of research and feel that CodeIgniter is a code choice of framework to use to help quicken the transfer. Before looking at a framework, I started constructing a list of objects to create classes out of: photos users forum topics forums blogs blog posts comments The trouble I have now, is I do understand where these generic/universal objects fall into the CI MVC setup. What is the best way to organise this kind of stuff? These classes can generally be used on multiple models/views/controllers.

• Modules already committed, client doesn't pay, what should I do?

  - by John

  So the story is simple, early stage EU portal hired me to do some extra modules. I got all the source code for local testing, did my job, committed new code. Now I am out of this project but client still haven't paid me yet and he is not even thinking about that. It has been couple of months and no contract was signed so I can't take any legal actions. What should I do with all the source code? Sell it? Run exact copy of that portal? Make all portal publicly available?

• Backup Script - Could Not Open Input File

  - by Iestyn

  this is the backup script that I've got going: http://pastebin.com/4g4E6wUz This is the cron info: /usr/local/bin/php /home/backups/backup-db.php --filename-dated ALL No matter what I do, I keep on getting this error: Could not open input file: /home/backups/backup-db.php - That's the correct location of the file. I just don't know what else to try, I feel I've been working on this for so long now that I've explored every avenue, on the other hand sometimes I think that the time I've spent on it is clouding my thoughts and I'm missing something stupidly obvious. Just wondering if someone can give me a few pointers? Also on a last note, does anyone know of a way/article to auto generate a full backup of cPanel every * amount of days and store it in a location that I want? Kind Regards.

• how to rewrite or redirect old or missing or invalid url to 404 page

  - by kath

  I recently upgraded a site and almost all URLs have changed. I have redirected all of them (or so I hope) but it may be possible that some of them have slipped by me. Is there a way to somehow catch all invalid URLs and send the user to a certain page I am using PHP Thanks so much! error file is already in .htaccess but seems nothing going to change you can see the error file as below AddHandler application/x-httpd-php5s .php ErrorDocument 404 /content/404.php <IfModule mod_rewrite.c> RewriteEngine on RewriteBase / here are 2 different url one the first one is old one which i edited and the secound one is edited one #1 old one (which is no longer on the server) http://adsbuz.com/vehicles-cars/toyoya/2009-toyota-land-cruiser-gxr-4686.htm #2 the editet one which is on the server http://adsbuz.com/vehicles-cars-for-sale/toyoya/2009-toyota-land-cruiser-gxr-4686.htm i need only the secound one with the vehicles-cars-for-sale because the other directory is already modified and its not on the server but as you can see after the (adsbuz) site name vehicles-cars and vehicles-cars-for-sale both are opening for same location I hope I made myself clear

• What is a light-weight "slideshow" script that could integrate w/ CMS?

  - by aslum

  I'm looking to reduce the footprint of my Strict html 4.01 front page. One possible way is to combine much of the "upcoming events" into a single small box, and have them automagically switch which one is displayed every few seconds. I'm sure there are a bunch of this kind of thing written already, and surely an open source one exists, but I haven't had much luck find one. I'd prefer javascript to jQuery as installing jQuery might not be an option, but if the best-fit script requires jQuery I'd certainly be willing to investigate that route. If it can display content from Wordpress that would be ideal.

• nginx: Disallow Acces to a Folder, except some subfolders

  - by user68202

  how it is possible to deny access to a folder, but execept some subfolders in it from "deny"? I tried something like this (in this order): #this subfolder shouldnt be denied and php scripts inside should be executable location ~ /data/public { allow all; } #this folder contains many subfolders that should be denied from public access location ~ /data { deny all; return 404; } ... which doesnt work correctly. Files inside the /data/public folder are accessible (all other in /data are denied as it should be), but PHP files are not executed anymore in the /data/public folder (if i dont add these restrictions, the php files are executable). What is wrong? How can it be correct? I think theres a better way to do it. It would be very nice if anyone can help me with this :).

• Blocking path scanning

  - by clinisbut

  I'm seeing in my access log a number of request very suspicious: /i /im /imaa /imag /image /images /images/d /images/di /images/dis They part from a known resource (in the above example /images/disrupt.jpg). All comming from same IP. Requests varies from 1/sec to 10/sec, seems somewhat random. It's obviously they are trying to find something and seems they are using a script. How do I block this kind of behaviour? I though of blocking the IP request, at least for a given time. Keeping in mind that: Request intervals seems legitimate (at least I think so). I don't want to end blocking a search engine bot, which may find 404 urls too (and that's a different problem, I know). ¿Do they use always same IP?

• Depending on another open source library: copy/paste code or include

  - by user5794

  I'm working on a large class and started implementing new features that need graphics. I started writing the graphics functions myself, but I know that open source libraries exist that can provide me with this functionality without me having to write it myself. The problem is that I prefer the class to be self-sufficient and not dependent on any other library. If I don't write it myself, I would have to ask the user to make sure a graphics library is already installed (less user-friendly). If I write it myself, I do a lot more work than I have to. I could also copy/paste some of the relevant code into my own class, but not sure about the disadvantages of doing this (it's an open source library that matches my license, so I'm not concerned with legality, just programming-wise if there are disadvantages). So what should I do: copy paste code from the external library write the code myself so it's truly self-sufficient ask the user to download and install another library

• How serious/common are wordpress updating issues

  - by gyaani_guy

  I am currently deciding between a CMS (joomla OR wordpress )to dive deep into. I think I would go for wordpress, but the only thing thats holding me back are any potential issues with updating wordpress- that updating wordpress can break plugins, but is necessary because of security issues. How drastic are the changes in wordpress? say over a period of 2-3 years? from the perspective of someone intending to dive head first in its code. Should I fear regular updates breaking stuff ? Thanks

• Passing class names or objects?

  - by nischayn22

  I have a switch statement switch ( $id ) { case 'abc': return 'Animal'; case 'xyz': return 'Human'; //many more } I am returning class names,and use them to call some of their static functions using call_user_func(). Instead I can also create a object of that class, return that and then call the static function from that object as $object::method($param) switch ( $id ) { case 'abc': return new Animal; case 'xyz': return new Human; //many more } Which way is efficient? To make this question broader : I have classes that have mostly all static methods right now, putting them into classes is kind of a grouping idea here (for example the DB table structure of Animal is given by class Animal and so for Human class). I need to access many functions from these classes so the switch needs to give me access to the class

• MCrypt Module, Rijndael-256

  - by WernerCD

  An outside company is redoing our company Intranet. During some basic usage I disovered that the "User Edit" screens, with the "Password: *" boxes have the password in plain text, with the text box "type=password" to "hide" the password. The passwords are not store in the database as plain text, they are stored encrypted using "rijndael-256" cypher using the mcrypt module. I know that if I encrypt a password with SHA*, the password is "Unrecoverable" via one-way encryption. Is the same of MCrypt Rijndael-256 encryption? Shouldn't an encrypted password be un-recoverable? Are they blowing smoke up my rear or just using the wrong technology?

• handling the holding of money on a platform

  - by user1716672

  We are building a platform for a client, developed in Yii, where users can top up their account on the platform with money from paypal. Users can upload files and buy access to each others files. User can also gift other users with money. I was thinking that when users top up their account, the money goes rom their Paypal to the merchant account of the website. So all users' money goes to one merchant account. Then, any transactions on the platform are simply recorded on the platform and each users' balance is the maximum amount they can withdraw from the merchant account. Is this the right approach? Legally, are there any problems?

• Is there any way to prevent Googlebar from breaking Friendly 404s

  - by TecBrat

  This might be considered a continuation of this question. If I output HTML after my 404 header, It displays properly in IE and FF unless the user has Google bar instaled. If I try header('HTTP/1.x 404 Not Found'); header("Location: http://www.example.com/?content=404_error"); die(); then I'm getting 302 from the redirect. It seems to overrule the 404 Supposedly if your output is larger than 512 bytes, the toolbar isn't supposed to override the page, but It seems to do it anyway. I found a setting in Google's Toolbar that said "Provide suggestions on navigation errors". Turning that off provides me with the behaviour I want my visitors to experience. Does anyone know if Google provides a way for a developer to over-ride that setting for all visitors?

• Using a CDN for CMS software (multiple sites)

  - by SmokeyPHP

  I'm currently researching ideas for the media management side of a CMS I'm writing. I was looking at having images served from a CDN which is fine on a single site, but I want all sites that run the CMS to make use of a CDN (which will most likely be a custom developed one, rather than a third party service like S3). My main question is: Is a multi-site CDN a good idea? I can't think of a downside, but have probably missed something - obviously they won't share the same folder, as I invisage the requests to be css.cdnsite.com/example.com/style.css or something along those lines. Having multiple sites in the same place will obviously make it easier for us to manage, as well as being cheaper, but then I wonder if it'll be worth it... Long story short: How should the CMS handle user uploaded media (separate installations) Just keep a local copy of all assets and serve them from the same site, like in days of yore? Keep a local copy, force site to use www. and have CDN subdomains per site? Or use a single separate CDN for all sites? Apologies for the length of this question, not sure if this should be multiple questions or not, as all parts are kind of related and could affect each other.

• Validation and Error Generation when using the Data Mapper Pattern

  - by AndyPerlitch

  I am working on saving state of an object to a database using the data mapper pattern, but I am looking for suggestions/guidance on the validation and error message generation step (step 4 below). Here are the general steps as I see them for doing this: (1) The data mapper is used to get current info (assoc array) about the object in db: +=====================================================+ | person_id | name | favorite_color | age | +=====================================================+ | 1 | Andy | Green | 24 | +-----------------------------------------------------+ mapper returns associative array, eg. Person_Mapper::getPersonById($id) : $person_row = array( 'person_id' => 1, 'name' => 'Andy', 'favorite_color' => 'Green', 'age' => '24', ); (2) the Person object constructor takes this array as an argument, populating its fields. class Person { protected $person_id; protected $name; protected $favorite_color; protected $age; function __construct(array $person_row) { $this->person_id = $person_row['person_id']; $this->name = $person_row['name']; $this->favorite_color = $person_row['favorite_color']; $this->age = $person_row['age']; } // getters and setters... public function toArray() { return array( 'person_id' => $this->person_id, 'name' => $this->name, 'favorite_color' => $this->favorite_color, 'age' => $this->age, ); } } (3a) (GET request) Inputs of an HTML form that is used to change info about the person is populated using Person::getters <form> <input type="text" name="name" value="<?=$person->getName()?>" /> <input type="text" name="favorite_color" value="<?=$person->getFavColor()?>" /> <input type="text" name="age" value="<?=$person->getAge()?>" /> </form> (3b) (POST request) Person object is altered with the POST data using Person::setters $person->setName($_POST['name']); $person->setFavColor($_POST['favorite_color']); $person->setAge($_POST['age']); *(4) Validation and error message generation on a per-field basis - Should this take place in the person object or the person mapper object? - Should data be validated BEFORE being placed into fields of the person object? (5) Data mapper saves the person object (updates row in the database): $person_mapper->savePerson($person); // the savePerson method uses $person->toArray() // to get data in a more digestible format for the // db gateway used by person_mapper Any guidance, suggestions, criticism, or name-calling would be greatly appreciated.
