• Drupal 7: Unable to find the wrapper "public"

  - by Raheel Hasan

  Can anyone help me with this major issue I have. I have downloaded my Drupal 7 site running fine on current server, but I cant run it on localhost or on the new server where I am trying to move it... It just gives me the "White Screen of Death"... and after commenting "set_error_handler" in boostrap.inc, I find out that the errors are all related to "public://" wrapper. This is how all the errors look like: Warning: is_dir() [function.is-dir]: Unable to find the wrapper "public" - did you forget to enable it when you configured PHP All these errors are coming from the following file: /includes/file.inc

• High level programming logic, design, pattern

  - by Muhammad Shahzad

  I have been doing programming from last 7 years, getting better and better, but still i think that am lacking something. I have been doing work in JOOMLA, MAGENTO, WP, Custom PHP, Opencart, laravel, codeignitor. Sometimes i need to design logic for a huge database application, in the applications we need nesting loops and queries, although i follow OOPS standards, ORM etc, still i feel i need more robust coding designs. I need to know how can i improve these things, so that code remain neat, efficient and faster. Also how big webapps like facebook twitter tests there code speed? How high level programmers choose design patterns. If you can help me find something useful with examples?

• Converting a stopwatch time to milliseconds (regex)

  - by Nick

  I'm trying to figure out the best way to convert a string containing a time to an integer number of milliseconds. I'm using a suboptimal way using a bunch of preg_match()'s and some array handling, but I was wondering if there was an elegant way. Here are some example stopwatch times (some wouldn't actually be seen on a stopwatch but need to be converted anyway): 3:34:05.81 34:05 5 (just 5 seconds) 89 (89 seconds) 76:05 (76 minutes, 5 seconds) Millseconds will not extend past 2 decimal places. You can give me an example using either PHP or Javascript regex functions. Thanks!

• Compute column widths in a HTML-like manner (based on cell contents)

  - by cipak

  Hi, I have a grid of data that I want to export to RTF, PDF etc. using various (and not perfect) PHP converters/generators. What I am missing most is the HTML table automatic adjustment of column widths based on the lengths of strings in the cells (strings contain line breaks which complicate things a bit, as they should be preserved). I need an algorithm that, given the contents of the cells (plain text), a total width of the table and an average width of a character, would return a width for each column. I wouldn't want to reinvent the wheel if something is already available. Of course it can't be perfect if the font is variable width, but an approximation would do just fine. Or maybe it could have a configurable table with widths for each character. Any hint would be appreciated. Thank you.

• -1 as a return value

  - by dimadima

  This question is specifically about PHP, but I'm guessing it might be applicable to other languages as well. I've noticed that between PHP4 and PHP5, the designers of the language shifted away from using -1 as a return value to using constants or other forms of output. This makes sense, as -1 is not particularly evocative, and I'm guessing this practice led to confusion. That said, I am sometimes inclined to return -1 when I want to quickly add another return option to a function, and -1 often seems like a perfectly valid way to express the outcome I am coding for. So here are my questions: Is my observation generally correct, regarding the move away from -1 as a return value in PHP5 vs PHP4? What are the cons of returning -1, beyond for the reason I mentioned above, wherein the -1 return value doesn't contribute positively to code clarity?

• Javascript form validation events

  - by user307922

  Hi All, I am making a small form for a php app and had a question regarding javascript validation. What is the best event to run the javascript validation on the input value? Is it the "focusout" event? I used "focusout" to originally but it creates problems when the user hits enter while they are still focused on any particular field in the form. Should I run the js validation when the user clicks submit? Just looking for some advice. Thanks! Chuck

• Gaining application/module context from a symfony task

  - by Martin Chatterton

  I have written a reporting suite, and I have a specific report that builds a CSV file. Serving this file via a browser on demand isn't an issue, but I need to be able to build this CSV file nightly, and email round a link to be able to download it. Essentially, I need to be able to replace a specific action with a symfony task, run via cron. So how do I gain application/module context from a symfony task? And secondly, how would I invoke the SwiftMailer library from a symfony task? I'm using symfony v1.4.4 and PHP v.5.2.13. Thanks in advance for your help.

• How to escape/strip special characters in the LaTeX document?

  - by Igor

  We implemented the online service where it is possible to generate PDF with predefined structure. User can choose a LaTeX template and then compile it with an appropriate inputs. The question we worry about is the security, that the malicious user was not able to gain shell access through the injection of special instruction into latex document. We need some workaround for this or at least a list of special characters that we should strip from the input data. Preferred language would be PHP, but any suggestions, constructions and links are very welcomed. PS. in few word we're looking form mysql_real_escape_string for LaTeX

• Unread email notifier, most practical approach

  - by Michael Pasqualone

  I'm in the process of writing a small php-cli script that will loop over over my personal inbox and then send me an SMS via a gateway. The question I have is: As will have the script launch via cron every 10 minutes, if there is an email sitting in my inbox that is not read before the next script launch then I will receive 2 sms. Does any one (pseudocode will do) have any idea what the best practice would be in php5 to ensure only 1 SMS is sent? What I am currently learning towards is towards storing the message ID in a sqlite DB and flagging a field whether an SMS has been sent or not - but wondering if there is an easier way?

• Is is possible to parse a web page from the client side for a large number of words and if so, how?

  - by Technoh

  I have a list of keywords, about 25,000 of them. I would like people who add a certain < script tag on their web page to have these keywords transformed into links. What would be the best way to go and achieve this? I have tried the simple javascript approach (an array with lots of elements and regexping/replacing each) and it obviously slows down the browser. I could always process the content server-side if there was a way, from the client, to send the page's content to a cross-domain server script (I'm partial to PHP but it could be anything) but I don't know of any way to do this. Any other working solution is also welcome.

  So I have this shopping list coded in php and js: http://www.whatcouldicook.com/recipes/planner So people can add, delete or sort the list and thats fine, I dont want multiple lists and instead just have a list item containing a heading tag to represent a new list.

• How to recover from a fatal error "Allowed memory size exhausted"

  - by Matthieu

  Hi everybody, Do you know any solution to recover from the PHP fatal error : "Allowed memory size ... exhausted" I have a shutdown function that is called when a fatal error appear. This function create an ErrorException from it, and logs it. The problem is : when there is no more memory available, it can't log the error (I log in Firebug, via FirePHP, with Zend Framework). So what i mean by "how to recover from it", is how to perform basic error log, and let Zend Framework send the Headers, so that the error is logged (in Firebug in my case) as any other error ? Thanks

• FreshBooks API Libraries

  - by Hristo

  Hello, I am posting this question as I couldn't find the answer (which is probably very easy, but apparently not for me) anywhere.. I am new to FreshBooks (no only the API) and I want to use it for some automatically generated invoices. I was trying to run some of the source code examples (the PHP and JS libraries in particular): http://developers.freshbooks.com/api/samplecode/ The problem is that I get an error message: "Connection error" Do I need to set up anything else in the example files besides my API and token obtained from the FreshBooks site? P.S.: I am running the examples from a local server but I don't believe that's the problem. Thank you very much in advance!

  - by Earthman Web

  I am looking for a solution using preg_replace or similar method to change: <li id="id1" class="authorlist" /> <li id="id2" class="authorlist" /> <li id="id3" class="authorlist" /> to <option id="id1" class="authorlist" /> <option id="id2" class="authorlist" /> <option id="id3" class="authorlist" /> I think I have the pattern correct, but not sure how to do the replacement part...

• generating dynamic word documents for mass mailing

  - by bluesystem

  I need to generate a mass mailing based on a word document model with PHP. Given is a database with the adresses and the data that need to be filled in my word model. I want to generate a single word document with the different adresses and field contents from the database. We have a Linux server and the COM object is not avalaible. Is there a ready to use class to do this? Did you had any experiance with PHPWord? What is the best practice in this case? In the ideal case the client should just upload th word master document, with the fields that need to be filled and then fusioned to a multiple pages word document containing the whole mailing.

• Are protected constructors considered good practice?

  - by Álvaro G. Vicario

  I'm writing some little helper classes to handle trees. Basically, I have a node and a special root node that represents the tree. I want to keep it generic and simple. This is part of the code: <?php class Tree extends TreeNode{ public function addById($node_id, $parent_id, $generic_content){ if( $parent = $this->findNodeById($parent_id) ){ $parent->addChildById($node_id, $generic_content); } } } class TreeNode{ public function __construct($node_id, $parent_id, $generic_content){ // ... } protected function addChildById($node_id, $generic_content){ $this->children[] = new TreeNode($this->node_id, $node_id, $generic_content); } } $Categories = new Tree; $Categories->addById(1, NULL, $foo); $Categories->addById(2, NULL, $bar); $Categories->addById(3, 1, $gee); ?> My questions: Is it sensible to force TreeNode instances to be created through TreeNode::addById()? If it's so, would it be good practise to declare TreeNode::__construct() as private/protected?

• Redirect to Apache built-in 404 page with mod_rewrite?

  - by Pekka

  Is there a way to actively serve Apache's default, built-in 404 page for a number of URLs using mod_rewrite? Not a custom error document, but a rule like RewriteCond %{REQUEST_URI} ^/dirname/pagename RewriteRule -- serve 404 page ----- I know how to build a PHP page that sends the 404 header and have mod_rewrite redirect all the URLs there but I would prefer a solution that is based on mod_rewrite only. I just had the idea of redirecting to a non-existent address: RewriteCond %{REQUEST_URI} ^/dirname/pagename RewriteRule .* /sflkadsölfkasdfölkasdflökasdf but that would give the user the message "/sflkadsölfkasdfölkasdflökasdf does not exist" on the error page, which looks a bit unprofessional.
