  • Is there a way to implement an XMPP client or message reciever that can recieve all the messages fro

    - by roberto
    Basically im trying to build a bot that can send a message using one of many accounts out to a user and be able to receive messages to that account it originally used process and do whatever I need it to do. So far I found the JAXL library (http://code.google.com/p/jaxl/) but based on examples it is only able to handle one user at a time. Any suggestions or ideas? thank you in advanced. btw if there is anyway to make the server automatically forward those messages to another program or whatever that works just as well.

  • Validate a date range within MySQL query

    - by fishcracker
    (This question may seem easy or kind of noobish, by that I pardon my ignorance.) I used PDO query to use SELECT then fetch some values, it comes to a point that I need to fetch only some entries that within its start date and end date. My database +----------+-----------------+----------------------+--------------------+ | id (INT) | title (VARCHAR) | start_date (VARCHAR) | end_date (VARCHAR) | +----------+-----------------+----------------------+--------------------+ | 1 | buddy | 2012-11-26 | 2012-11-30 | | 2 | metro | 2012-12-05 | 2012-12-20 | | 3 | justin | 2012-11-28 | 2012-12-01 | +----------+-----------------+----------------------+--------------------+ My query is as follows: $query = "SELECT title, start_date, end_date FROM debts WHERE start_date >= CURDATE() AND end_date >= CURDATE()"; What I want to achieve is whenever the start_date is today or greater but not exceeding the end_date it will be valid. This will return the row for id 1, however if I change the start_date to 2012-11-25, it will fail due to the first condition on AND. I'm really confuse on this since I am new to this, is there any built-in function to handle this kind of situation?

  • Sending Variables in Post without the input tag

    - by abhishekgupta92
    I want to send only one variable via the post method. I have queried the database and have to post $row[id] variable to the page along with the form. To send the user's input we simply write like <input type="text" name="xyz"></input> and then we access it as $_POST[xyz]. This way we can send a variable that a user write. But, I want to send something that user has not written but there in my sending file as $row['id']. So, I want to send this variable as well. How can I do that? And also how will I be able to access that?

  • How can I concatenate two mp3 files with different bit rates

    - by Scott
    I have FFmpeg installed on my linux web server. When I execute the following code, I have intermittent results. I think I have figured out that the MP3s do not compile when they have different bitrates. exec ('cat '. $pair['source_file'] . ' ' . $pair['translated_word_file'] . '>' . $temp_mp3); I might have found some articles online that reference taking them apart and then bundling them back together at a consistent bitrates. I have confirmed that this won't really work with basic "cat" function and that "sox" can be used IF they have the same sample rate. The issue now becomes "What is the best way to get them to the same sample rate?"

  • cakephp datetime insertion behaviour

    - by littlechad
    hi everyone this is a cakePHP question about datetime database insertion mismatch, i jumped in to this project while the whole thing is already built around 70%. here's what happen, every time i insert a data that contain a datetime, the inserted time doesn't match the inputted date, and the mismatch has no pattern or what ever, in some table the differences is 5 hours, while in others it could be 12 hours, 7 hours, or even 15 hours. i have traced this by investigating the controller, the model, the app_controller, everything but i don't find anything that indicate a datetime insertion rules. if the view : echo $form->input('start_date', array('label' => __l('start date')); i can't even find in the controller anything like: $this->data['current_controller']['start_date'] = $this->data['current_controller']['start_date']; when i use pr($this-data); to print the posted data, this is shown: [start_date] => Array ( [month] => 02 [day] => 16 [year] => 2011 [hour] => [min] => [meridian] => ) so i figured doing something like: $yearMonDay = $this->data['current_controller']['start_date']['year']."-"; $yearMonDay .= $this->data['current_controller']['start_date']['month']."-"; $yearMonDay .= $this->data['current_controller']['start_date']['day']; if(!empty($this->data['current_controller']['start_date']['hour'])){ $hourMinSec = $this->data['current_controller']['start_date']['hour'].":"; $hourMinSec .= $this->data['current_controller']['start_date']['min'].":"; $hourMinSec .= $this->data['current_controller']['start_date']['meridian']; }else{ $hourMinSec = "00:00:00"; } $this->data['Deal']['start_date'] = $yearMonDay." ".$hourMinSec; just to make sure the funny thing is that those posted datetime is inserted into the database with the mismatch value anyway. it's getting pretty frustrating, is there any suggestion on where else should i find the codes that define how the datetime should be inserted? or probably give me a clue on how to override those mismatched insertion rules? thanks

  • Selenium: How to click an HTML button element?

    - by Andrew
    I have button on the page that being used as a link to another page. So when the user clicks the button they are redirected to the right page. I am using the Selenium extension for PHPUnit and I would like to test that the button is correctly redirecting the user. Here is the HTML that I am trying to test: <button onclick="window.location='/sponsor';" value="Continue" type="button" id="sponsorContinue" name="sponsorContinue">Continue</button> I have tried a lot of different approaches to click the button, but I can't seem to get any of them to work: $this->click("//button[@id='sponsorContinue']"); This command executes and does not throw any errors, but the page isn't redirected. It works fine when I manually click the button. What should I do?

  • Approaches to timing out sessions on a web app using AJAX autorefreshes

    - by Braintapper
    I'm writing a web application that autorefreshes data with an AJAX call at set intervals. Because it's doing that, server side user sessions never time out, since the last activity is refreshed with every ajax call. Are there good client side rules I could implement to time out the user? I.e. should I track mouse movements in the browser, etc., or should I point the AJAX calls to URLs that don't refresh the session? I like that my AJAX calls hit a session-enabled URL, because I can also validate that the user is logged in, etc. Any thoughts in terms of whether I should even bother timing out the users?

  • Create a multicolor selectbox on Symfony2

    - by Ninsuo
    I try to create the following field : <select name="test"> <option value="1">a</option> <option value="2">b</option> <option value="3" style="font-weight: bold; color: red;">c</option> <option value="4">d</option> <option value="5">e</option> </select> This creates a 2-color selectbox : But in Symfony2, I do not know how to apply a class to a single option. If in my view I do : {{ form_widget(myForm.test, { 'attr': { 'class': 'red', } }) }} Or if in my form I do : $builder->add('test', 'choice', array( 'required' => true, 'choices' => array('a', 'b', 'c', 'd', 'e'), 'attr' => array('class' => 'red'), )); The attribute is stored into the <select> tag and apply to the whole selectable values. How do I apply a class to an <option> in Symfony2 ?

  • How to do left joins with least-n-per-group query?

    - by Nate
    I'm trying to get a somewhat complicated query working and am not having any luck whatsoever. Suppose I have the following tables: cart_items: +--------------------------------------------+ | item_id | cart_id | movie_name | quantity | +--------------------------------------------+ | 0 | 0 | braveheart | 4 | | 1 | 0 | braveheart | 9 | | . | . | . | . | | . | . | . | . | | . | . | . | . | | . | . | . | . | +--------------------------------------------+ movies: +------------------------------+ | movie_id | movie_name | ... | +------------------------------+ | 0 | braveheart | . | | . | . | . | | . | . | . | | . | . | . | | . | . | . | +------------------------------+ pricing: +-----------------------------------------+ | id | movie_name | quantity | price_per | +-----------------------------------------+ | 0 | braveheart | 1 | 1.99 | | 1 | braveheart | 2 | 1.50 | | 2 | braveheart | 4 | 1.25 | | 3 | braveheart | 8 | 1.00 | | . | . | . | . | | . | . | . | . | | . | . | . | . | | . | . | . | . | | . | . | . | . | +-----------------------------------------+ I need to join the data from the tables, but with the added complexity that I need to get appropriate price_per from the pricing table. Only one price should be returned for each cart_item, and that should be the lowest price from the pricing table where the quantity for the cart item is at least the quantity in the pricing table. So, the query should return for each item in cart_items the following: +---------------------------------------------+ | item_id | movie_name | quantity | price_per | +---------------------------------------------+ Example 1: Variable passed to the query: cart_id = 0. Return: +---------------------------------------------+ | item_id | movie_name | quantity | price_per | +---------------------------------------------+ | 0 | braveheart | 4 | 1.25 | | 1 | braveheart | 9 | 1.00 | +---------------------------------------------+ Note that this is a minimalist example and that additional data will be pulled from the tables mentioned (particularly the movies table). How could this query be composed? I have tried using left joins and subqueries, but the difficult part is getting the price and nothing I have tried has worked. Thanks for your help. EDIT: I think this is similar to what I have working with my "real" tables: SELECT t1.item_id, t2.movie_name, t1.quantity FROM cart_items t1 LEFT JOIN movies t2 ON t2.movie_name = t1.movie_name WHERE t1.cart_id = 0 Assuming I wrote that correctly (I quickly tried to "port over" my real query), then the output would currently be: +---------------------------------+ | item_id | movie_name | quantity | +---------------------------------+ | 0 | braveheart | 4 | | 1 | braveheart | 9 | +---------------------------------+ The trouble I'm having is joining the price at a certain quantity for a movie. I simply cannot figure out how to do it.

  • preg_replace only replaces first occurrence then skips to next line

    - by Dom
    Got a problem where preg_replace only replaces the first match it finds then jumps to the next line and skips the remaining parts on the same line that I also want to be replaced. What I do is that I read a CSS file that sometimes have multiple "url(media/pic.gif)" on a row and replace "media/pic.gif" (the file is then saved as a copy with the replaced parts). The content of the CSS file is put into the variable $resource_content: $resource_content = preg_replace('#(url\((\'|")?)(.*)((\'|")?\))#i', '${1}'.url::base(FALSE).'${3}'.'${4}', $resource_content); Does anyone know a solution for why it only replaces the first match per line?

  • Regexp look-behind to match internet speeds

    - by Sandman
    So the user may search for "10 mbit" after which I want to capture the "10" so I can use it in a speed-search rather than a string-search. This isn't a problem, the below regexp does this fine: if (preg_match("/(\d+)\smbit/", $string)){ ... } But, the user may search for something like "10/10 mbit" or "10-100 mbit". I don't want to match those with the above regexp - they should be handled in another fashion. So I would like a regexp that matches "10 mbit" if the number is all-numeric as a whole word (i.e. contained by whitespace, newline or lineend/linestart) Using lookbehind, I did this: if (preg_match("#(?<!/)(\d+)\s+mbit#i", $string)){ Just to catch those that doesn't have "/" before them, but this matched true for this string: "10/10 mbit" so I'm obviously doing something wrong here, but what?

  • Send post data while opening SSE connection

    - by Prosto Trader
    I'm trying to establish SSE connection and do some long-taking actions on server-side, informing user about how it goes through SSE events. Actually, I don't understand how would I send some data along with new connection. I have to combine regular ajax with new EventSource or there is a way to transfer post data inside that event? Here is what I have so far, and I need to send pretty big JSON with the request. Is it possible or the only way to send data is GET? var source = new EventSource('/terminal/ajax-put-packet-trade-order/');

  • MySQL.. search using Fulltext or using Like? What is better?

    - by user156814
    I'm working on a search feature for my application, I want to search all articles in the database. As of now, I'm using a LIKE in my queries, but I want to add a "Related Articles" feature, sort of like what SO has in the sidebar (which I see as a problem if I use Like). What's better to use for MySQL searching, Fulltext or Like... or anything else I might not know about? Also, I'm using the Kohana Framework, so If anybody knows an easy way to do fulltext matching using the query builder, I'd appreciate that. Thanks.
