• REGEX HELP: SUBDOMAIN CHECK

ONLY Last character: Cannot be a symbol I want it to spit out false if it fails the test. Can anyone help me out with this? Thanks! Also any other limitations do you guys think should be in there?

• MySQLi Prepared Statement Query Issue

  - by Benjamin Flak

  I'm relatively new to MySQLi prepared statements, and running into an error. Take this code: $user = 'admin'; $pass = 'admin'; if ($stmt = $mysqli->query("SELECT * FROM members WHERE username='$user' AND password='$pass'")) { echo $stmt->num_rows; } This will display "1", as it should. This next piece of code though, returns "0": $user = 'admin'; $pass = 'admin'; if ($stmt = $mysqli->prepare("SELECT * FROM members WHERE username=? AND password=?")) { $stmt->bind_param("ss", $user, $pass); $stmt->execute(); echo $stmt->num_rows; } Any ideas why?

• checking if records exists in DB, in single step or 2 steps?

  - by Sinan

  Suppose you want to get a record from database which returns a large data and requires multiple joins. So my question would be is it better to use a single query to check if data exists and get the result if it exists. Or do a more simple query to check if data exists then id record exists, query once again to get the result knowing that it exists. Example: 3 tables a, b and ab(junction table) select * from from a, b, ab where condition and condition and condition and condition etc... or select id from a, b ab where condition then if exists do the query above. So I don't know if there is any reason to do the second. Any ideas how this affects DB performance or does it matter at all?

• mySQL - One large query vs Ajax indivdual queries

  - by Mark

  Hi guys, I guess no one will have a definative answer to this but considered predictions would be appriciated. I am in the process of developing a mySQL database for a web application and my question is: Is it more efficient to make a single query that returns a single row using AJAX or To request 100 - 700 rows when the user will likely only ever use the results of two or three? Really I am asking what is heavier for the server 2-3 requests with one result or 1 request with 100 - 700 results? Thanks, Mark

• How to query_posts after the current timestamp and sort reverse chronologically?

  - by Jody Heavener

  I am using the following code in Wordpress to query events (custom post type) and order them by date chronologically.. query_posts( array( 'post_type' => 'events', 'showposts' => 10, 'orderby' => 'meta_value_num','meta_key' => '_ecmb_datetime' ) ); Where the meta key _ecmb_datetime is, this is the timestamp of the event. I don't want to show events that have already happened, so my question is how do I only show events happening after my current time, and how do I sort reverse chronologically? Any help is greatly appreciated

• Outputing resized animated gif to browser using imagick

  - by Freeman

  I intent to resize an animated gif and outputing it to the browser on-the-fly. My problem is that when I save the resized image it is of good quality, but if I echo it to the browser it is of poor quality and the animation is removed. Here is the code:` header("Content-type:image/gif"); try { /* Read in the animated gif */ $animation = new Imagick("images/nikks.gif"); /*** Loop through the frames ***/ foreach ($animation as $frame) { /*** Thumbnail each frame ***/ $frame->thumbnailImage(200, 200); /*** Set virtual canvas size to 100x100 ***/ $frame->setImagePage(200, 200, 0, 0); } /*** Write image to disk. Notice writeImages instead of writeImage ***/ //$animation->writeImages("images/nikkyo1.gif",true); echo $animation; } catch(Exception $e) { echo $e-getMessage(); } `

• Open currency exchange rate API thingy

  The table is: currency_name exchange_rate USD 1.000000 EUR 1.194929 CAD 0.942142 etc. What I want is to make a simple little cron job Python script to run every couple hours and update these values in the database. Are there any open APIs? I mean I am like 99% sure Yahoo! or Google finance has something like this but cannot find. Maybe someone here has done this?

• 'AND' vs '&&' as operator

  - by ts

  Actually, i am facing a codebase where developpers decided to use 'AND' and 'OR' instead of '&&' and '||'. I know that there is difference in operators precedence (&& goes before 'and'), but with given framework (prestashop to be precise) is clearly not a reason. So, my question: which version are you using? Is 'and' more readable than '&&'? || there is ~ difference?

• Debugging CodeIgniters 404 errors

  - by Alex

  I'm having a nightmare uploading my site to the production server. The site runs fine locally and on a staging server (exactly the same server, settings as the production site). However when I deploy to production I'm getting a 404 error from CI. CodeIgniters 404 error pages are frustrating because it seems as if i can't access other libraries from them. How can I go about debugging the error? See which controller is trying to be called etc.

• IE won't start session from an iframe?..

  - by jayarjo

  The task was to bypass login form on remote server with a session_id acquired through a call to server's web API. So that user wouldn't have to login twice. Since there's no way to set cookies for different domain. What we came up to was - put a little file on remote server, to which we pass encrypted session_id from hidden iframe and which is supposed to start a proper session for a remote app, which is then loaded in another iframe. This approach works fine in FF/Chrome, but not IE... However if I copy url to self-made remote authorization script from iframe's src attribute to to IE's address bar and load it from there, session get's created as expected. But for some reason it just doesn't want to do the same from an iframe. Does anyone have any clue, why this is happening?

• Can't find a Wordpress image/photo gallery plugin

  - by mgroves

  I've been looking at Wordpress plugins for photo galleries (so maybe this is for superuser.com), and I've been very frustrated so far. It seems like what I'd like to do would be a very common use case: Admin: Be able to upload multiple pictures (at a time) Admin: Be able to assign a "gallery" to those pictures as I upload them User: Be able to go to a page with a (paged) list of all galleries User: Be able to click on gallery and view the images (again, probably paged) in that gallery User: Be able to click on an image to get larger/largest sizes User: Be able to leave comments on individual pictures (this is a "nice to have") The images/galleries could be totally independent of posts/pages, but it would be nice to be able to embed those images/galleries into posts/pages when necessary. Is there anything out there like this that I'm missing? I've tried a handful of plugins and none of them seem to be for a use case anywhere close to what I'm looking for. One of the reasons I'm trying to use Wordpress is to reduce time spent coding everything I want.

• url encoded forward slashes breaking my codeigniter app

  - by Ian Cook

  i’m trying to create a url string that works like this: /app/process/example.com/index.html so in other words, /app/process/$URL i then retrieve the url with $this->uri->segment(3); the forward slashes in the URL will of course be a problem accessing uri segments, so i’ll go ahead and url encode the URL portion: /app/process/example.com%2Findex.html .. but now I just get a 404 saying ... Not Found The requested URL /app/process/example.com/index.html was not found on this server. it appears that my url encoding of forward slashes breaks CI’s URI parser. what can i do to get around this problem?

• How to fetch populated associated models in CakePHP when calling read()

  - by Code Commander

  I have the following Models: class Site extends AppModel { public $name = "Site"; public $useTable = "site"; public $primaryKey = "id"; public $displayField = 'name'; public $hasMany = array('Item' => array('foreignKey' => 'siteId')); public function canView($userId, $isAdmin = false) { if($isAdmin) { return true; } return array_key_exists($this->id, $allowedSites); } } and class Item extends AppModel { public $name = "Item"; public $useTable = "item"; public $primaryKey = "id"; public $displayField = 'name'; public $belongsTo = array('Site' => array('foreignKey' => 'siteId')); public function canView($userId, $isAdmin = false) { // My problem appears to be the next line: return $this->Site->canView($userId, $isAdmin); } } In my controller I am doing something like this: $result = $this->Item->read(null, $this->request->id); // Verify permissions if(!$this->Item->canView($this->Session->read('userId'), $this->Session->read('isAdmin'))) { $this->httpCodes(403); die('Permission denied.'); } I notice that in Item->canView() $this->data['Site'] is populated with the column data from the site table. But it merely an array and not an object. On the other hand $this->Site is a Site object, but it has not been populated with the column data from the site table like $this->data. What is the proper way to have CakePHP get the associated model as the object and containing the data? Or am I going about this all wrong? Thanks!

• Overriding PEAR error handler

  - by Rolf

  Hi everyone, I'm currently working on an application that requires lots of external libraries. My job right now is set a unique error handler that will manage every error. So far, I found 7 different types of PEAR errors: PEAR_ERROR_RETURN: PEAR_ERROR_EXCEPTION: PEAR_ERROR_CALLBACK: PEAR_ERROR_EXCEPTION: PEAR_ERROR_PRINT: PEAR_ERROR_TRIGGER: PEAR_ERROR_DIE: I want to handle only the serious error (like the native E*_ERROR). The only problem is I have absolutely no idea about PEAR error criticity ! Those names are more related to the way of handling them than to their seriousness... Is there a real documentation about it ? I guess a better solution would consist in using their pushErrorHandling, but I just don't understand how to use it... If someone here knows, I'd be grateful... Thanks in advance !

• Magento: Syncing product/category translations from "Store 1 > German Store View" to "Store 2 > German Store View"

  - by mattalexx

  For two different store Views using the same locale, it is easy to manage translations for miscellaneous text that's stored in CSV files. It's just a question of configuring the locale correctly so the correct CSV files will be used. But my client has entered a bunch of translations for products and categories into the admin by changing the scope to "Store 1 German" and setting the translations. But now he has Store 2, with a German store view. How does he keep "Store 1 German Store View" and "Store 2 German Store View" in sync?
