    - by Industrial
    Hi! If I would need to build up an array with OOP based PHP, would this be the proper way to do it? class MyClass { $array = array(); function addElement($value) { $this->array[] = $value; } function fetch() { $return = $this->memcached->getMulti($this->array); return $return; } } PHP file where it will be used: <?php $this->myClass->addElement('key1'); $this->myClass->addElement('key1'); $this->myClass->addElement('key1'); $var = $this->myClass->fetch(); Thanks a lot

  • How to include file from seperate remote folder in Netbeans (PHP Development)

    - by webworm
    I have a PHP project setup in Netbeans (v6.8) where all the PHP files are on a remote server and in a single directory. Whenever I save files locally they are updated on the remote server via SFTP. I now need to edit a remote JavaScript file to add some jQuery logic but the file is located within a different directory on the webserver. How to I add this JavaScript file such that when it is saved or updated it is transferred to it's own location on the server? When I attempt to create the file locally within NetBeans it saves to the same directory as my PHP files. I would like to be able to continue using NetBeans rather than doing this all manually using an SFTP client and a text editor. Thanks in advance.

  • How to store and retrieve pictures using PHP?

    - by user1276898
    I am building a webpage using PHP to search within my database. I am able to do a query and get the data to show on my page. I also have a picture that is related to each record. Let's say something like a picture ID for each employee. I am wondering what is the best way to store and retrieve pictures in order to get it show using PHP. Is there a way to store all the pictures in the subfolder like " image" and retrieve the pictures using PHP? I tried to search around on the internet, but I get confused. Also, when I type something in the search box and click the button, is there a way to keep the input in the search box without erasing it? Thank you very much.

  • jQuery/JSON/PHP failing

    - by user730936
    I am trying to call a php script that accepts JSON data, writes it into a file and returns simple text response using jQuery/AJAX call. jQuery code : $("input.callphp").click(function() { var url_file = myurl"; $.ajax({type : "POST", url : url_file, data : {'puzzle': 'Reset!'}, success : function(data){ alert("Success: " + data); }, error : function (data) { alert("Error: " + data); }, dataType : 'text' }); }); PHP Code : <?php $thefile = "new.json"; /* Our filename as defined earlier */ $towrite = $_POST["puzzle"]; /* What we'll write to the file */ $openedfile = fopen($thefile, "w"); fwrite($openedfile, $towrite); fclose($openedfile); echo "<br> <br>".$towrite; ?> However, the call is never a success and always gives an error with an alert "Error : [Object object]".

  • PHP Variable Passing in Foreach on same page

    - by tooly228
    I've been struggling this for a while and I simply can't figure this out. Here is my code: <?php foreach($list as $id =>$name) { echo("<td style=\"vertical-align:middle;\"> <a href=\"item=$id#confirm\" role=\"button\" data-toggle=\"modal\"> Buy</a></td></tr>"); }?> <html> <div class="modal small hide fade" id="confirm" tabindex="-1" role="dialog" aria- labelledby="myModalLabel" aria-hidden="true"> <a href="redeem.php?item=<?php echo $id; ?>"><button class="btn btn-danger"> Buy</button></a></div> The main issue here is that the $id from the foreeach is not the same as the $id in the div class link. Instead the link is the end value of the foreach list.

  • Access property from include inside a class method in PHP

    - by Jojo
    How do you make a class property available to the other included file inside the same class' method? // file A.php class A { private $var = 1; public function go() { include('another.php'); } } in another file: // this is another.php file // how can I access class A->var? echo $var; // this can't be right Is this possible given the scope. If var is an array then we can use extract but if var is not, we can wrap it in an array. Is there a better way? Thanks!

  • how to get the value of an php array in jQuery

    - by user1933824
    i have a PHP code that will obtain the total images of a certain website via CURL, and put it inside an PHP loop. $z=1; for ($i=0;$i<=sizeof($images_array);$i++) { ....<img src = "$images_array[$i]" id="$z"> .. $z++; } a user can then scan through the array with a prev/next button and the current image being shown will be displayed in my $('$current_image').val(1); $.post("curl_fetch.php?url="+ extracted_url, { }, function(response){ $('#loader').html($(response).fadeIn('slow')); $('#current_image').val(1); // insert loop value in .val() when i click a button, i want to get the value of the array, and not the loop value $(function() { $(document).on('click','.submit', function () { var img = $('#current_image').val(); //get the array value, not the loop value alert(img); });}); now, how do i properly get the array value in my $('#current_image').val(1); in Jquery.

  • php calling classes functions in separate pages

    - by sys_debug
    I've worked with J2EE recently and like the idea of struts.xml where I can handle the redirection to pages based on return string from action classes. In PHP, in my new under-development site, I am trying to follow the MVC standards without an MVC framework used from the internet. So I create the controllers, models and views (empty now). The only thing I am really stuck at is when I submit the form in view (insert_product.php) then I will need to create another php page to handle the post data and pass them to controllers. Anyway of avoiding creating those pages and maybe having something like struts.xml? Even if I can post data directly to controller class, that would be good. Thanks,

  • PHP and Javascript cookies

    - by shummel7845
    Can I access a cookie written with jQuery's cookie plug-in with PHP? I know you can't set Javascript equal to PHP or vice versa, but IN ESSENCE is: $.cookie('var') = $_COOKIE['var']? Again, I know you can't set them equal to each other, but if I set it in jQuery and then go to another page, can PHP access it? I've read lots of posts about this, but I can't seem to find an answer to this part. Note, if I look in Firefox's preferences, I can see the cookies are there, so I know they're set.

  • Has "Killer Game Programming in Java" by Andrew Davison been rendered useless? What new tutorial should I follow? [duplicate]

    - by BDillan
    This question already has an answer here: Killer Game Programming [Java 3D] outdated? 5 answers Its pathetic how it was created in 2005 not so long ago when the Java 3D 1.31 API was released. Now after downloading the source code off the books website and implementing it onto my work-space it cant run. (The 3D Shooter Ch. 23) I downloaded Java 3D 1.5 API, installed it- went back to my source code and javax.media ect.., and EVERY imported class within the game simply couldn't be resolved... they are all outdated.. Please do not say how its meant for a positive curvature in your game development skills. No ~ I got the book to understand how to code 3D textures/particle systems/games. Without seeing results how can I learn? If there is still hope for this book please tell me. Otherwise what other books match this one in Game Programming? This one was very well organized, documented and long. I am not looking for a 3D game prog. book on Java. Rather one that has the same reputation as this one but is a bit newer..

  • How to ...set up new Java environment - largely interfaces...

    - by Chris Kimpton
    Hi, Looks like I need to setup a new Java environment for some interfaces we need to build. Say our system is X and we need to interfaces to systems A, B and C. Then we will be writing interfaces X-A, X-B, X-C. Our system has a bus within it, so the publishing on our side will be to the bus and the interface processes will be taking from the bus and mapping to the destination system. Its for a vendor based system - so most of the core code we can't touch. Currently thinking we will have several processes, one per interface we need to do. The question is how to structure things. Several of the APIs we need to work with are Java based. We could go EJB, but prefer to keep it simple, one process per interface, so that we can restart them individually. Similarly SOA seems overkill, although I am probably mixing my thoughts about implementations of it compared to the concepts behind it... Currently thinking that something Spring based is the way to go. In true, "leverage a new tech if possible"-style, I am thinking maybe we can shoe horn some jruby into this, perhaps to make the APIs more readable, perhaps event-machine-like and to make the interface code more business-friendly, perhaps even storing the mapping code in the DB, as ruby snippets that get mixed in... but thats an aside... So, any comments/thoughts on the Spring approach - anything more up-to-date/relevant these days. EDIT: Looking a JRuby further, I am tempted to write it fully in JRuby... in which case do we need any frameworks at all, perhaps some gems to make things clearer... Thanks in advance, Chris

  • How to design highly scalable web services in Java?

    - by Kshitiz Sharma
    I am creating some Web Services that would have 2000 concurrent users. The services are offered for free and are hence expected to get a large user base. In the future it may be required to scale up to 50,000 users. There are already a few other questions that address the issue like - Building highly scalable web services However my requirements differ from the question above. For example - My application does not have a user interface, so images, CSS, javascript are not an issue. It is in Java so suggestions like using HipHop to translate PHP to native code are useless. Hence I decided to ask my question separately. This is my project setup - Rest based Web services using Apache CXF Hibernate 3.0 (With relevant optimizations like lazy loading and custom HQL for tune up) Tomcat 6.0 MySql 5.5 My questions are - Are there alternatives to Mysql that offer better performance for what I'm trying to do? What are some general things to abide by in order to scale a Java based web application? I am thinking of putting my Application in two tomcat instances with httpd redirecting the request to appropriate tomcat on basis of load. Is this the right approach? Separate tomcat instances can help but then database becomes the bottleneck since both applications access the same database? I am a programmer not a Db Admin, how difficult would it be to cluster a Mysql database (or, to cluster whatever database offered as an alternative to 1)? How effective are caching solutions like EHCache? Any other general best practices? Some clarifications - Could you partition the data? Yes we could but we're trying to avoid it. We need to run a lot of data mining algorithms and the design would evolve over time so we can't be sure what lines of partition should be there.

  • Is the output of Eclipse's incremental java compiler used in production? Or is it simply to support Eclipse's features?

    - by Doug T.
    I'm new to Java and Eclipse. One of my most recent discoveries was how Eclipse comes shipped with its own java compiler (ejc) for doing incremental builds. Eclipse seems to by default output incrementally built class files to the projRoot/bin folder. I've noticed too that many projects come with ant files to build the project that uses the java compiler built into the system for doing the production builds. Coming from a Windows/Visual Studio world where Visual Studio is invoking the compiler for both production and debugging, I'm used to the IDE having a more intimate relationship with the command-line compiler. I'm used to the project being the make file. So my mental model is a little off. Is whats produced by Eclipse ever used in production? Or is it typically only used to support Eclipse's features (ie its intellisense/incremental building/etc)? Is it typical that for the final "release" build of a project, that ant, maven, or another tool is used to do the full build from the command line? Mostly I'm looking for the general convention in the Eclipse/Java community. I realize that there may be some outliers out there who DO use ecj in production, but is this generally frowned upon? Or is this normal/accepted practice?

  • How do you encode Algebraic Data Types in a C#- or Java-like language?

    - by Jörg W Mittag
    There are some problems which are easily solved by Algebraic Data Types, for example a List type can be very succinctly expressed as: data ConsList a = Empty | ConsCell a (ConsList a) consmap f Empty = Empty consmap f (ConsCell a b) = ConsCell (f a) (consmap f b) l = ConsCell 1 (ConsCell 2 (ConsCell 3 Empty)) consmap (+1) l This particular example is in Haskell, but it would be similar in other languages with native support for Algebraic Data Types. It turns out that there is an obvious mapping to OO-style subtyping: the datatype becomes an abstract base class and every data constructor becomes a concrete subclass. Here's an example in Scala: sealed abstract class ConsList[+T] { def map[U](f: T => U): ConsList[U] } object Empty extends ConsList[Nothing] { override def map[U](f: Nothing => U) = this } final class ConsCell[T](first: T, rest: ConsList[T]) extends ConsList[T] { override def map[U](f: T => U) = new ConsCell(f(first), rest.map(f)) } val l = (new ConsCell(1, new ConsCell(2, new ConsCell(3, Empty))) l.map(1+) The only thing needed beyond naive subclassing is a way to seal classes, i.e. a way to make it impossible to add subclasses to a hierarchy. How would you approach this problem in a language like C# or Java? The two stumbling blocks I found when trying to use Algebraic Data Types in C# were: I couldn't figure out what the bottom type is called in C# (i.e. I couldn't figure out what to put into class Empty : ConsList< ??? >) I couldn't figure out a way to seal ConsList so that no subclasses can be added to the hierarchy What would be the most idiomatic way to implement Algebraic Data Types in C# and/or Java? Or, if it isn't possible, what would be the idiomatic replacement?

  • Are Java's public fields just a tragic historical design flaw at this point?

    - by Avi Flax
    It seems to be Java orthodoxy at this point that one should basically never use public fields for object state. (I don't necessarily agree, but that's not relevant to my question.) Given that, would it be right to say that from where we are today, it's clear that Java's public fields were a mistake/flaw of the language design? Or is there a rational argument that they're a useful and important part of the language, even today? Thanks! Update: I know about the more elegant approaches, such as in C#, Python, Groovy, etc. I'm not directly looking for those examples. I'm really just wondering if there's still someone deep in a bunker, muttering about how wonderful public fields really are, and how the masses are all just sheep, etc. Update 2: Clearly static final public fields are the standard way to create public constants. I was referring more to using public fields for object state (even immutable state). I'm thinking that it does seem like a design flaw that one should use public fields for constants, but not for state… a language's rules should be enforced naturally, by syntax, not by guidelines.

  • Named my RPi 512MB @jerpi_bilbo

    - by hinkmond
    To keep our multiple Raspberry Pi boards apart from each other, I've now named my RPi Model B w/512MB: "jerpi_bilbo", which stands for Java Embedded Raspberry Pi - Bilbo (named after the Hobbit from the J.R.R. Tolkien stories). I also, set up a Twitter account for him. You can follow him at: @jerpi_bilbo He's self-tweeting, manual prompted so far (using Java Embedded 7.0 and twitter4j Java library). Works great! I'm setting him up to be automated self-tweeting soon, so watch for that... Here's a pointer to the open source twitter4j Java library: download here Just unzip and extract out the twitter4j-core-2.2.6.jar and put it on your Java Embedded classpath. Here's how @jerpi_bilbo uses it to Tweet with his Java Embedded runtime: import twitter4j.*; import java.io.* public final class Tweet { public static void main(String[] args) { String statusStr = null; if ((args.length 0) && (args[0] != null)) { statusStr = args[0]; } else { statusStr = new String("Hello World!"); } // Create new instance of the Twitter class Twitter twitter = new TwitterFactory().getInstance(); try { Status status = twitter.updateStatus(statusStr); System.out.println ("Successfully updated the status to: " + status.getText()); } catch (Exception e) { e.printStackTrace(); } } } That's all you need. Java Embedded rocks the RPi! And, @jerpi_bilbo is alive... Hinkmond

  • Unexpected ArrayIndexOutOfBoundsException in JavaFX application, refering to no array

    - by Eugene
    I have the following code: public void setContent(Importer3D importer) { if (DEBUG) { System.out.println("Initialization of Mesh's arrays"); } coords = importer.getCoords(); texCoords = importer.getTexCoords(); faces = importer.getFaces(); if (DEBUG) { System.out.println("Applying Mesh's arrays"); } mesh = new TriangleMesh(); mesh.getPoints().setAll(coords); mesh.getTexCoords().setAll(texCoords); mesh.getFaces().setAll(faces); if (DEBUG) { System.out.println("Initialization of the material"); } initMaterial(); if (DEBUG) { System.out.println("Setting the MeshView"); } meshView.setMesh(mesh); meshView.setMaterial(material); meshView.setDrawMode(DrawMode.FILL); if (DEBUG) { System.out.println("Adding to 3D scene"); } root3d.getChildren().clear(); root3d.getChildren().add(meshView); if (DEBUG) { System.out.println("3D model is ready!"); } } The Imporeter3D class part: private void load(File file) { stlLoader = new STLLoader(file); } public float[] getCoords() { return stlLoader.getCoords(); } public float[] getTexCoords() { return stlLoader.getTexCoords(); } public int[] getFaces() { return stlLoader.getFaces(); } The STLLoader: public class STLLoader{ public STLLoader(File file) { stlFile = new STLFile(file); loadManager = stlFile.loadManager; pointsArray = new PointsArray(stlFile); texCoordsArray = new TexCoordsArray(); } public float[] getCoords() { return pointsArray.getPoints(); } public float[] getTexCoords() { return texCoordsArray.getTexCoords(); } public int[] getFaces() { return pointsArray.getFaces(); } private STLFile stlFile; private PointsArray pointsArray; private TexCoordsArray texCoordsArray; private FacesArray facesArray; public SimpleBooleanProperty finished = new SimpleBooleanProperty(false); public LoadManager loadManager;} PointsArray file: public class PointsArray { public PointsArray(STLFile stlFile) { this.stlFile = stlFile; initPoints(); } private void initPoints() { ArrayList<Double> pointsList = stlFile.getPoints(); ArrayList<Double> uPointsList = new ArrayList<>(); faces = new int[pointsList.size()*2]; int n = 0; for (Double d : pointsList) { if (uPointsList.indexOf(d) == -1) { uPointsList.add(d); } faces[n] = uPointsList.indexOf(d); faces[++n] = 0; n++; } int i = 0; points = new float[uPointsList.size()]; for (Double d : uPointsList) { points[i] = d.floatValue(); i++; } } public float[] getPoints() { return points; } public int[] getFaces() { return faces; } private float[] points; private int[] faces; private STLFile stlFile; public static boolean DEBUG = true; } And STLFile: ArrayList<Double> coords = new ArrayList<>(); double temp; private void readV(STLParser parser) { for (int n = 0; n < 3; n++) { if(!(parser.ttype==STLParser.TT_WORD && parser.sval.equals("vertex"))) { System.err.println("Format Error:expecting 'vertex' on line " + parser.lineno()); } else { if (parser.getNumber()) { temp = parser.nval; coords.add(temp); if(DEBUG) { System.out.println("Vertex:"); System.out.print("X=" + temp + " "); } if (parser.getNumber()) { temp = parser.nval; coords.add(temp); if(DEBUG) { System.out.print("Y=" + temp + " "); } if (parser.getNumber()) { temp = parser.nval; coords.add(temp); if(DEBUG) { System.out.println("Z=" + temp + " "); } readEOL(parser); } else System.err.println("Format Error: expecting coordinate on line " + parser.lineno()); } else System.err.println("Format Error: expecting coordinate on line " + parser.lineno()); } else System.err.println("Format Error: expecting coordinate on line " + parser.lineno()); } if (n < 2) { try { parser.nextToken(); } catch (IOException e) { System.err.println("IO Error on line " + parser.lineno() + ": " + e.getMessage()); } } } } public ArrayList<Double> getPoints() { return coords; } As a result of all of this code, I expected to get 3d model in MeshView.

And moreover it doesn't point to any my array. What is this? And why does it happen?
