  • Can I make PDOStatement->fetchObject not use non-member variables?

    - by threendib
    Lets say I have a class like this: Class User { var $id var $name; } And I run a query using PDO in php like so: $stm = $db->prepare('select * from users where id = :id'); $r = $stm->execute(array(':id' => $id)); $user = $r->fetchObject('User'); If I vardump my user object it has all kinds of other fields in it that I have not defined in the User class. Obviously I could make my query specific so that it only gives me back the fields I need/want. But if I don't want to do that is there any way to make this work the way I want it to? I like the idea of fetchObject, because it's one line of code to create this object and set member variables for me. I just don't want it to set variables I haven't defined in my class.

  • Sync offline JQuery Mobile form

    - by Dimas
    My name is Dimas and I work as a developer in a hospital. I've developed a web form with JQuery Mobile which is accessed from an Android tablet. It sends data (text and FILES) to the server (PHP) and it's saved in a MySQL database. This tablets are used by doctors that are visiting the patients in their homes. Some of these patients live in remote areas with very bad Internet connection, so I'm thinking on use HTML5 Offline feature to solve these situations. I started reading about it but I'm newbie with this technology. I've some questions: Do you think this is the best/easiest solution? If I could save the form data in a local sqlite storage when the tablet is offline, how I could synchronize it with the data in MySQL server when the tablet become online? Thanks

  • "Did you mean" feature on a dictionary database

    - by Hazar
    I have a ~300.000 row table; which includes technical terms; queried using PHP and MySQL + FULLTEXT indexes. But when I searching a wrong typed term; for example "hyperpext"; naturally giving no results. I need to "compansate" little writing errors and getting nearest record from database. How I can accomplish such feaure? I know (actually, learned today) about Levenshtein distance, Soundex and Metaphone algorithms but currently not having a solid idea to implement this to querying against database. Best regards. (Sorry about my poor English, I'm trying to do my best)

  • Why is this MySQL Join Statement not Working?

    - by Timmy
    Here is my code: $query2 = mysql_query("SELECT * FROM categories WHERE parent = $id JOIN SELECT * FROM posts WHERE main_nav_page = '$idTwo'"); while ($row2 = mysql_fetch_assoc($query2)) { $id = $row2['id']; $name = $row2['name']; $slug = $row2['slug']; $subMenuOrder = $row2['sub_menu_order']; echo "<tr>\n"; echo "<td>&nbsp; -- $name</td>\n"; echo "</tr>\n"; } Is my syntax wrong?

    - by Camran
    I have this piece of code here below: $fq.=" + (fritidsboende_uth_from:[$fritids_uth_from TO *] AND fritidsboende_uth_to:[* TO $fritids_uth_to]) OR (fritidsboende_uth_from:'1972-01-01T01:01:00Z' AND fritidsboende_uth_to:'2019-01-01T01:01:00Z')"; I have noticed my app doesn't get anything behind the colon, in this part of the code: OR (fritidsboende_uth_from:'1972-01-01T01:01:00Z' // Notice the colon in the date string I get this error msg: Unrecognized date string: '1972-01-01T01'. Nothing from behind the colon is there though. How should I 'escape' it so that the colon is properly recognized? Its PHP... Thanks

  • MySQL Cluster data nodes - slow SELECTs

    - by Boyan Georgiev
    Hi to all. First off, I'm new to MySQL Cluster. This is my pain: I've managed to setup a MySQL Cluster with two data nodes, two SQL nodes and one management server. Everything works pretty well, except the following: my data nodes are spread across an intranet link which incurs latency into communications between the data nodes. Apparently, due to MySQL Cluster's internal partitioning schemes, when my PHP application pulls data from the cluster via SELECT queries, parts of the data are pulled from both data nodes. This makes the page appear onscreen REALLY slowly. If I bring one data node offline, the data can only be pulled from that single remaining data node, and thus, the final result (HTML output) appears on the screen in a very timely fashion. So, my question is this: can the data nodes/cluster be told to pull data from partitions stored only on a particular data node?

  • How to do MVC form url formatting?

    - by dqhendricks
    I am using PHP. I want to create an MVC setup from scratch to learn more about how MVC works. I want to use clean urls with slashes as delimiters for the arguments. How do people do this when it comes to GET method forms? Or do people avoid GET method forms all together? As of right now the ways I can imagine are: Don't use GET method forms (although this makes it harder to let users bookmark/link in some cases). Use AJAX instead of form submission (although what do you do for SEO and JS disablers?). Have page submit to itself with post method, then reform the post vars into an url, then rerout to that url using headers (seems like wasted resources). Any suggestions or suggested reading welcome.

  • How Does a Login system generally work with OOP?

    - by fakingfantastic
    Sorry if this is a badly formed question, but I'm trying to make my web applications (using PHP) more OO. *EDIT* I'm developing the Framework myself */EDIT* Everything is great so far, I've made a Front Controller system that taps into a MVC system. The FC figures out what page you want, loads the specific page Controller (*EDIT* which extends an abstract Controller Object */EDIT*), which gets anything it needs from Models, and then calls the appropriate View. Very basic. But now, I need to make an admin section (quasi-CMS). How does a login system fit into the grand scheme of things? Do you set controllers as needing a login? If so, how? What If you only want certain views of a controller requiring login? Thanks in advance.

  • How to overload shutdown function?

    - by Michal M
    I am using Kohana (v3) framework but I believe it's not tied to a particular framework. What I have is basically an app with a front-end, where I want to use Kohana's native Kohana::shutdown_handler(), but I also have a part of the - RESTful API - where I don't want colourful and html-encoded exception reporting. I want a plain text reporting. The way I thought it might work is to register another shutdown function in API's controller abstract class constructor, but then I realised register_shutdown_function() works differently to set_exception_handler() and instead of replacing it adds another function to the shutdown procedure. What's worse PHP doesn't allow "unregistering" shutdown functions and that's where my problem lies. What to do, if you want to use another shutdown function instead of one already registered?

  • 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

  • How to 'insert if not exists' in MySQL?

    - by warren
    I started by googling, and found this article which talks about mutex tables. I have a table with ~14 million records. If I want to add more data in the same format, is there a way to ensure the record I want to insert does not already exist without using a pair of queries (ie, one query to check and one to insert is the result set is empty)? Does a unique constraint on a field guarantee the insert will fail if it's already there? It seems that with merely a constraint, when I issue the insert via php, the script croaks.

  • apc cache compression

    - by Massimo
    I want to store some key value. I see memcache api supports on-the-fly compression: memcache_set( obj, var, value, MEMCACHE_COMPRESSED, ttl ) What about apc ? I cannot find any doc. My goal, for example in php : function cache( $key, $value ) { $data = serialize( $value ); if ( strlen( $data ) >= 1024 ) $data = 'z' . gzcompress( $data, 1 ); else $data = '=' . $data; return apc_store( $key, $data, $ttl ); }

  • Loop through custom template hooking thing

    - by tarnfeld
    Hi, I am building a template system for emailing people that currently works in the format of: $array['key1'] = "text; $array['key2'] = "more text"; <!--key1--> // replaced with *text* <!--key2--> // replaced with *more text* For this particular project I have a nested array with this kind of structure: $array['object1']['nest1']['key1'] = "text"; $array['object2']['next1']['key1'] = "more text"; <!--[object1][nest1][key1]--> // replaced with *text* <!--[object2][nest1][key1]--> // replaced with *more text* What would be the best way to do this in PHP? I thought I could loop through the arrays but then I just lost my trail of thought and got lost in what I was doing! All help would be appreciated!! Thanks

  • 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!

  • -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?

  • 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.

  • 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

  • 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

  • Gaining 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.

  • 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!

  • 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?
