  • For REST, how do I receive posted data using PHP?

    - by netrox
    I want to set up a tiny RESTful interface for my web services using PHP. The problem is that I looked at frameworks and I cannot figure out how do I recieve the posted data without field names? For example, if a server posts data to my server, I cannot figure out how do I get it without needing the postfield (POST variables). Traditionally, with forms, people send post data with field names such as this: curl_setopt($ch, CURLOPT_POSTFIELDS, postfield=postvalue); and I would use PHP code like this: $postvalue=$_POST[postfield]; to get value of postfield but since the server posting data is not using postfield and is just sending XML, how do I get it without fields? How do I capture the XML? That's where I am lost.

  • Servlet receiving data both in ISO-8859-1 and UTF-8. How to URL-decode?

    - by AJPerez
    I've a web application (well, in fact is just a servlet) which receives data from 3 different sources: Source A is a HTML document written in UTF-8, and sends the data via <form method="get">. Source B is written in ISO-8859-1, and sends the data via <form method="get">, too. Source C is written in ISO-8859-1, and sends the data via <a href="http://my-servlet-url?param=value&param2=value2&etc">. The servlet receives the request params and URL-decodes them using UTF-8. As you can expect, A works without problems, while B and C fail (you can't URL-decode in UTF-8 something that's encoded in ISO-8859-1...). I can make slight modifications to B and C, but I am not allowed to change them from ISO-8859-1 to UTF-8, which would solve all the problems. In B, I've been able to solve the problem by adding accept-charset="UTF-8" to the <form>. So the <form> sends the data in UTF-8 even with the page being ISO. What can I do to fix C? Alternatively, is there any way to determine the charset on the servlet, so I can call URL-decode with the right encoding in each case?

  • How can I get PHP to compile a LaTeX document if it (www-data) can't get access to the required packages?

    - by Mark Jones
    I have a PHP script that compiles LaTeX documents with the use of: exec('cd /path/to/doc && /usr/bin/latexmk -pdf filename.tex'); This is working for some of my LaTeX documents but my latest document doesn't compile and a look at the log reveals: !pdfTeX error: pdflatex (file ecrm1000): Font ecrm1000 at 600 not found ==> Fatal error occurred, no output PDF file produced! Which I have found is the result of LaTeX not being able to see the required font packages. When I run the same compile command under my username the document compiles as it should. So my question is, how can I get PHP (executing as www-data) to get access to the necessary LaTeX packages? I have tried installing the required package under the www-data account using: sudo -u www-data sudo apt-get install texlive-fonts-recommended but it askes for www-data's password, which I don't believe was set by me and isn't anything I've thrown at it. I'm running Ubuntu 12.04 if it's any help.

  • Autocorrelation method for pitch determination: what is the input data form?

    - by harsh
    I have read a code for pitch determination using autocorrelation method. Can anybody please tell what would be the input data (passed as argument to DetectPitch()) function here: double DetectPitch(short* data) { int sampleRate = 2048; //Create sine wave double *buffer = malloc(1024*sizeof(short)); double amplitude = 0.25 * 32768; //0.25 * max length of short double frequency = 726.0; for (int n = 0; n < 1024; n++) { buffer[n] = (short)(amplitude * sin((2 * 3.14159265 * n * frequency) / sampleRate)); } doHighPassFilter(data); printf("Pitch from sine wave: %f\n",detectPitchCalculation(buffer, 50.0, 1000.0, 1, 1)); printf("Pitch from mic: %f\n",detectPitchCalculation(data, 50.0, 1000.0, 1, 1)); return 0; }

  • How do I use price data in one table for a calculation that is stored in another table?

    - by shane
    I'm still leanring PHP/MySQL but have learned quite a bit thanks to codies on StackOverflow. I'm trying to setup a sort of room reservations system using two tables: SETUP: Room price table: Has, prices for a type room a client may want to rent as well as the dates (day of week) they wish to use it. Pricing varies based on day of the week and per room. I've setup a different table for each room type as each room type carries different pricing for each day of the week. So, There is an Alpha room table, Bravo room, etc. Within Alpha table are headers for the days of the week with pricing pre-entered into the rows. Client info table: Has the name, address, date of room use, etc data for the specific client. EXAMPLE: Alpha-room price table: Sun = $100; Mon = $200; Tue=$300 and so on. Bravo-room price table: Sun = $100; Mon = $200; Tue=$300 and so on. Client data table: ClientName; date-of-room-use; address; day_subtotal; grand_total. QUESTION: I'm trying to find PHP code that will: look at the date of room use in the client data table, look up the associated cost for that date in the specific room pricing table, record that unit cost in the day subtotal of the client data table and sum a grand total in the grand total row of the client data table (assuming the room may be used more than one day by the customer). I know there's something to do with join but I'm finding it difficult to grasp the concept and, if someone can demonstrate using this example, I think I will have a better understanding of how to work this sort of transaction. Thank you ALL in advance for your suggestions or alternatvie approaches.

  • Impossible to be const-correct when combining data and it's lock?

    - by Graeme
    I've been looking at ways to combine a piece of data which will be accessed by multiple threads alongside the lock provisioned for thread-safety. I think I've got to a point where I don't think its possible to do this whilst maintaining const-correctness. Take the following class for example: template <typename TType, typename TMutex> class basic_lockable_type { public: typedef TMutex lock_type; public: template <typename... TArgs> explicit basic_lockable_type(TArgs&&... args) : TType(std::forward<TArgs...>(args)...) {} TType& data() { return data_; } const TType& data() const { return data_; } void lock() { mutex_.lock(); } void unlock() { mutex_.unlock(); } private: TType data_; mutable TMutex mutex_; }; typedef basic_lockable_type<std::vector<int>, std::mutex> vector_with_lock; In this I try to combine the data and lock, marking mutex_ as mutable. Unfortunately this isn't enough as I see it because when used, vector_with_lock would have to be marked as mutable in order for a read operation to be performed from a const function which isn't entirely correct (data_ should be mutable from a const). void print_values() const { std::lock_guard<vector_with_lock>(values_); for(const int val : values_) { std::cout << val << std::endl; } } vector_with_lock values_; Can anyone see anyway around this such that const-correctness is maintained whilst combining data and lock? Also, have I made any incorrect assumptions here?

  • Best way to gather, then import data into drupal?

    - by Frank
    I am building my first database driven website with Drupal and I have a few questions. I am currently populating a google docs excel spreadsheet with all of the data I want to eventually be able to query from the website (after it's imported). Is this the best way to start? If this is not the best way to start what would you recommend? My plan is to populate the spreadsheet then import it as a csv into the mysql db via the CCK Node. I've seen two ways to do this. http://drupal.org/node/133705 (importing data into CCK nodes) http://drupal.org/node/237574 (Inserting data using spreadsheet/csv instead of SQL insert statements) Basically my question(s) is what is the best way to gather, then import data into drupal? Thanks in advance for any help, suggestions.

  • What's faster to parse lots of data (5Mb): eval or json?

    - by AlfaTeK
    I want to get, via ajax, a collection of data objects and parse them into JS data. Currently I have 2 choices: - Server returns valid javascript code and then I eval it. - Server returns JSON object and then I eval the json object What is the fastest of these in Firefox? (I only care about the "parsing" performance, not server or data transfer)

  • SharePoint WSS 3.0 - Fastest approach to build data-bound forms?

    - by Rusty Scupper
    Pardon the vague question, but I've just inherited a project to build a couple dozen forms pulling data from a SQL 2005 database. The forms are mostly standard database lookups with just a couple updates so the data layer is very simple -- I'm the DBA -- but we just recently started using SharePoint WSS 3.0 for a departmental web site and I would prefer to integrate these forms into WSS rather than build a separate standalone ASP.NET app. I'm hoping there is some RAD framework out there that integrates with WSS for data bound forms. I've been searching online, but haven't found anything very promising and the data viewer web part in SharePoint Designer looks complicated to integrate with an external SQL database. TIA, Rusty

  • How to use data receive event in Socket class?

    - by affan
    I have wrote a simple client that use TcpClient in dotnet to communicate. In order to wait for data messages from server i use a Read() thread that use blocking Read() call on socket. When i receive something i have to generate various events. These event occur in the worker thread and thus you cannot update a UI from it directly. Invoke() can be use but for end developer its difficult as my SDK would be use by users who may not use UI at all or use Presentation Framework. Presentation framework have different way of handling this. Invoke() on our test app as Microstation Addin take a lot of time at the moment. Microstation is single threaded application and call invoke on its thread is not good as it is always busy doing drawing and other stuff message take too long to process. I want my events to generate in same thread as UI so user donot have to go through the Dispatcher or Invoke. Now i want to know how can i be notified by socket when data arrive? Is there a build in callback for that. I like winsock style receive event without use of separate read thread. I also do not want to use window timer to for polling for data. I found IOControlCode.AsyncIO flag in IOControl() function which help says Enable notification for when data is waiting to be received. This value is equal to the Winsock 2 FIOASYNC constant. I could not found any example on how to use it to get notification. If i am write in MFC/Winsock we have to create a window of size(0,0) which was just used for listening for the data receive event or other socket events. But i don't know how to do that in dotnet application.

  • Copying 6000 tables and data from sqlserver to oracle ==> fastest method?

    - by nazer555
    i need to copy the tables and data (about 5 yrs data, 6200 tables) stored in sqlserver, i am using datastage and odbc connection to connect and datstage automatically creates the table with data, but its taking 2-3 hours per table as tables are very large(0.5 gig, 300+columns and about 400k rows). How can i achieve this the fastes as at this rate i am able to only copy 5 tables per day but within 30 days i need move over these 6000 tables.

  • Easiest way to convert json data into objects with methods attached?

    - by John Mee
    What's the quickest and easiest way to convert my json, containing the data of the objects, into actual objects with methods attached? By way of example, I get data for a fruitbowl with an array of fruit objects which in turn contain an array of seeds thus: {"fruitbowl": [{ "name": "apple", "color": "red", "seeds": [] },{ "name": "orange", "color": "orange", "seeds": [ {"size":"small","density":"hard"}, {"size":"small","density":"soft"} ]} } That's all nice and good but down on the client we do stuff with this fruit, like eat it and plant trees... var fruitbowl = [] function Fruit(name, color, seeds){ this.name = name this.color = color this.seeds = seeds this.eat = function(){ // munch munch } } function Seed(size, density){ this.size = size this.density = density this.plant = function(){ // grow grow } } My ajax's success routine currently is currently looping over the thing and constructing each object in turn and it doesn't handle the seeds yet, because before I go looping over seed constructors I'm thinking Is there not a better way? success: function(data){ fruitbowl.length = 0 $.each(data.fruitbowl, function(i, f){ fruitbowl.push(new Fruit(f.name, f.color, f.seeds)) }) I haven't explored looping over the objects as they are and attaching all the methods. Would that work?

  • Get data from aspx.cs page to aspx page.

    - by Brad8118
    So I am using a jquery plug in that allows me to change the order of things in a list by dragging and dropping them. So my goal is to be able to grab a list of my objects (AlertInfo) and using it in a javascript function. I was able to use a json webservice call in a test project to pass the data to the page. But we don't have a webservice page now so I tried to grab it from a aspx.cs page and it hasn't worked. ///Aspx page: $.ajax({ type: "POST", url: "~/Alerts/GetAlerts", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { var data = eval("(" + msg.d + ")"); jQuery.each(data, function (rec) { AlertList[AlertList.length] = new objAlert(this.id, this.title, this.details, JSONDateSerializationFix(this.startdate), JSONDateSerializationFix(this.enddate)); UpdateDisplayList(); }) }, error: function (msg) { alert("BRAD" + msg); } The issue is that the Alerts page in "URL /Alerts/GetAlerts" is Alerts.aspx.cs. I can't figure out if I can use this ajax command to call a method in a aspx.cs page. //Code behind page aspx.cs [WebMethod] //[ScriptMethod(ResponseFormat = ResponseFormat.Json)] public string GetAlerts() { List list = AlertInfo.GetTestAlerts(); return new JavaScriptSerializer().Serialize(list); } public List GetAlertsList() { List list = AlertInfo.GetTestAlerts(); return list; ; } So I was hoping that I could load data into an asp control (dataList) and then grab the data //code behind page protected void Page_Load(object sender, EventArgs e) { dataListAlertList.DataSource = GetAlertsList(); dataListAlertList.DataBind(); } public static List<AlertInfo> GetTestAlerts() { List<AlertInfo> list = new List<AlertInfo>(); list.Add(new AlertInfo("0", "Alert 1 Title", "Alert 1 Detail", "10/10/2010", "10/10/2011")); list.Add(new AlertInfo("1", "Alert 2 Title", "Alert 2 Detail", "10/10/2010", "10/10/2011")); return list; } //.aspx page $(document).ready(function () { var a1 = $("#dataListAlertList").val(); // do fun stuff now. } But I keep getting undefined....

  • Possibility of language data type not mapped to shipped .NET Framework?

    - by John K
    Does anybody know of a managed programming language implemented on .NET that contains a specialized data type that is not mapped through to the Common Type System/FCL/BCL or one that does not have a shipped .NET equivalent (e.g. shipped standard types like System.String, System.Int32)? This question would likely come from the perspective of someone porting a compiler (although I'm not doing that). Is it as simple as the language creating a new data type outside the BCL/FCL for its specialized type? If so does this hinder interoperability between programming languages that are otherwise accustomed to mapping all their built-in data types to what's in the BCL/FCL, like Visual Basic and C#? I can imagine this situation might come about if an obscure language compiler of some kind is ported to .NET for which there is no direct mapping of one of its implicit data types to the shipped Framework. How is this situation supported or allowed in general? What would be the expectation of the compiler and the Common Language Runtime?

  • How to copy data from another workbook and paste onto related group rows?

    - by leighla
    Hi there, How do I copy data from all the workbooks in the folder onto workbook 1 into it's corresponding row groups? The attached images shows the sample worksheet is the file I want to paste data into (main template) and wb2 sample is a sample of one of the worksheets in the folder that I want to copy data from. As you can see, the workbook 2 does not include all of the tasks. So I need to copy all of the data from workbook 2 and paste it on the corresponding row group (col A) on original workbook. I then need to do this for all workbooks in the folder. Any help would be most appreciated!
