  • handle json request in PHP

    - by wo_shi_ni_ba_ba
    When making an ajax call, when contentType is set to application/json instead of the default x-www-form-urlencoded, server side (in PHP) can't get the post parameters. in the following working example, if I set the contentType to "application/json" in the ajax request, PHP $_POST would be empty. why does this happen? How can I handle a request where contentType is application/json properly in PHP? $.ajax({ cache: false, type: "POST", url: "xxx.php", //contentType: "application/json", processData: true, data: {my_params:123}, success: function(res){ }, complete: function(XMLHttpRequest, text_status) { } });

  • thumbs.db messing up my upload routine

    - by Scott B
    I'm getting the following error while uploading a zip archive. Warning: ZipArchive::extractTo(C:\xampplite\htdocs\testsite/wp-content/themes/mytheme//styles\mytheme/Thumbs.db) [ziparchive.extractto]: failed to open stream: Permission denied in C:\xampplite\htdocs\testsite\wp-content\themes\mythem\uploader.php on line 17 The thing I can't quite figure is that I don't see a thumbs.db file in either the zip archive or the destination folder that was created (the upload still processes, I just get these errors). The function is below, line 17 is commented... function openZip($file_to_open) { global $target; $zip = new ZipArchive(); $x = $zip->open($file_to_open); if($x === true) { $zip->extractTo($target); //this is line 17 $zip->close(); unlink($file_to_open); } else { die("There was a problem. Please try again!"); } }

  • PHP: Ajax ignores line foldings in the text

    - by ilnur777
    I don't understand why my AJAX script ignores all line foldings. I first type text to the textarea and then put onclick to send button. Here is my AJAX realization: // creating ajax object // ==================== function createRequestObject(){ try { return new XMLHttpRequest() } catch(e) { try { return new ActiveXObject('Msxml2.XMLHTTP') } catch(e) { try { return new ActiveXObject('Microsoft.XMLHTTP') } catch(e) { return null; } } } } // message options (save, cancel) // ============================== function form1(text){ var http = createRequestObject(); if(http){ http.open("GET", "my_script.php?text=" + text); http.onreadystatechange = function (){ if(http.readyState == 4){ alert("Ok!"); } } http.send(null); } else { document.location = "my_script.php?text=" + text; } } html form <p align="justify" style="margin-right:10; margin-left:10;"> <table style="margin-right:10; margin-left:10;" align="center" border="0" cellpadding="0" cellspacing="0" width="680"> <TBODY> <form name="fgform"> <tr> <td width="680" height="100" colspan="2"><p><textarea id="edit_text1" name="edit_text" rows="3" style="width: 680; height: 100;"></textarea></p></td> </tr> <tr> <td width="340"><p><input type="button" id="saveB" value="Save Text" style="color:rgb(0,204,0); background-color:white; border-width:1; border-color:rgb(225,218,202); border-style:solid; width:100;" onclick="form1(document.getElementById('edit_text1').value);"></p></td> <td width="340"><p align="right">&nbsp;</p></td> </tr> </form> </TBODY> </table>

  • jQuery, ajax request doesn't success with JSON on IE

    - by sylouuu
    I made an AJAX call and it works on FF & Chrome but not on IE 7-8-9. I'm loading a JSON file from my domain: $.ajax({ url: 'js/jquery.desobbcode.json', dataType: 'json', cache: false, success: function(json) { alert('ok'); }, error: function(xhr, errorString, exception) { alert("xhr.status="+xhr.status+" error="+errorString+" exception="+exception); } }); I also tried by adding contentType: 'application/json' but I receive the same output which is : xhr.status=200 error=parsererror exception=SyntaxError Unterminated string constant I checked my JSON file with JSONLint and it's OK. I checked if there is an extra comma and the content is also trimmed. See my JSON file If I put dataType: 'text', I receive the OK alert but a debug popup too. Could you help me? Regards.

  • Is calling of overload operator-> resolved at compile time?

    - by Brent
    when I tried to compile the code: (note: func and func2 is not typo) struct S { void func2() {} }; class O { public: inline S* operator->() const; private: S* ses; }; inline S* O::operator->() const { return ses; } int main() { O object; object->func(); return 0; } there is a compile error reported: D:\code>g++ operatorp.cpp -S -o operatorp.exe operatorp.cpp: In function `int main()': operatorp.cpp:27: error: 'struct S' has no member named 'func' it seems that invoke the overloaded function of "operator-" is done during compile time? I'd added "-S" option for compile only.

  • [Ruby] How can I randomly iterate through a large Range?

    - by void
    I would like to randomly iterate through a range. Each value will be visited only once and all values will eventually be visited. For example: (0..9).sort_by{rand}.map{|x| f(x)} where f(x) is some function that operates on each value. A Fisher-Yates shuffle could be used to increase efficiency, but this code is sufficient for many purposes. My problem is that sort_by will transform the range into an array, which is not cool because I am working with astronomically large numbers. Ruby will quickly consume a large amount of RAM trying to create a monstrous array. This is also why the following code will not work: tried = {} # store previous attempts bigint = 99**99 bigint.times { x = rand(bigint) redo if tried[x] tried[x] = true f(x) # some function } This code is very naive and quickly runs out of memory as tried obtains more entries. What sort of algorithm can accomplish what I am trying to do?

  • How to prevent button/movieclip from interfering with mouse events

    - by webfac
    I have a few swf's that are loaded into a base file using levels. These clips can be cycled through by means of a setInterval function or when the user clicks the next or previous button. However, when the user hovers over a defined 'hit' area which is ultimately a blank movie clip, the setTimeout call is then canceled. This works fine, except that now the 'hit' clip - being above everything - prevents the movies below accepting hit states, and if I move it to below everything else, when one mouses over any element in the loaded movie, it then acts as though the user has mouse out of the hit area. Is there any way to have this 'hit' clip do its job simply by determining if the mouse is over it, but without using an onRollOver function or equivalent? Much appreciated

  • Having a Link Only Appear If a Logged-In User Appears on a Dynamic List

    - by John
    Hello, For the function below, I would like the link <div class="footervote"><a href="http://www...com/.../footervote.php">Vote</a></div> to only appear if the logged in user currently appears on editorlist.php. (I. e. if the loginid in the function corresponds to any of the usernames that currently appear in editorlist.php.) Appearing on editorlist.php is something that is dynamic. How can I do this?

  • PHP Value Object auto create

    - by JonoB
    Assume that I have a class value object defined in php, where each variable in the class is defined. Something like: class UserVO { public $id; public $name; } I now have a function in another class, which is expecting an array ($data). function save_user($data) { //run code to save the user } How do I tell php that the $data parameter should be typed as a UserVO? I could then have code completion to do something like: $something = $data->id; //typed as UserVO.id $else = $data->name; //typed as UserVO.name I'm guessing something like the following, but this obviously doesnt work $my_var = $data as new userVO();

  • How to pass operators as parameters

    - by Rodion Ingles
    I have to load an array of doubles from a file, multiply each element by a value in a table (different values for different elements), do some work on it, invert the multiplication (that is, divide) and then save the data back to file. Currently I implement the multiplication and division process in two separate methods. Now there is some extra work behind the scenes but apart from the specific statements where the multiplication/division occurs, the rest of the code is identical. As you can imagine, with this approach you have to be very careful making any changes. The surrounding code is not trivial, so its either a case of manually editing each method or copying changes from one method to the other and remembering to change the * and / operators. After too many close calls I am fed up of this and would like to make a common function which implements the common logic and two wrapper functions which pass which operator to use as a parameter. My initial approach was to use function pointers: MultiplyData(double data) { TransformData(data, &(operator *)); } DivideData(double data) { TransformData(data, &(operator /)); } TransformData(double data, double (*func)(double op1, double op2)) { /* Do stuff here... */ } However, I can't pass the operators as pointers (is this because it is an operator on a native type?), so I tried to use function objects. Initially I thought that multiplies and divides functors in <functional> would be ideal: MultiplyData(double data) { std::multiplies<double> multFunct; TransformData(data, &multFunct); } DivideData(double data) { std::divides<double> divFunct; TransformData(data, &divFunct); } TransformData(double data, std::binary_function<double, double, double> *funct) { /* Do stuff here... */ } As you can see I was trying to use a base class pointer to pass the functor polymorphically. The problem is that std::binary_function does not declare an operator() member for the child classes to implement. Is there something I am missing, or is the solution to implement my own functor heirarchy (which really seems more trouble than it is worth)?

  • Python method to remove iterability

    - by Debilski
    Suppose I have a function which can either take an iterable/iterator or a non-iterable as an argument. Iterability is checked with try: iter(arg). Depending whether the input is an iterable or not, the outcome of the method will be different. Not when I want to pass a non-iterable as iterable input, it is easy to do: I’ll just wrap it with a tuple. What do I do when I want to pass an iterable (a string for example) but want the function to take it as if it’s non-iterable? E.g. make that iter(str) fails.

  • jquery scrollpane and scrollTo at same time

    - by steve
    Current demo here: http://www.studioimbrue.com/sites/eliotdudik I have the tabs system working wonderfully. I'm trying to get it so that if you're down a ways on the gallery and then click "foreword" or any menu item, it scrolls you back to 0,0. The current sliding code is as follows: $('#wrapper ul li').click(function() { $(window).scrollTo($(this).next('li'), 500, {offset: {top:0, left:-50}}, {easing:'easeOutExpo'} ); }); And I'm trying to add something like this under it: $('#menu li').click(function() { $(window).scrollTo(0,0, 500, {offset: {top:0, left:-50}}, {easing:'easeOutExpo'} ); }); It continues switching tabs, but it won't scroll back to the beginning!

  • n*n blocks and polygons

    - by OSaad
    Hi, this is actually meant to be for a function called roipoly in matlab but it can be considered a general case problem. Roipoly is a function which lets u select a polygon over an image, and returns a binary mask where u can use it to get indices of the desired polygon. (It is just a normal polygon after all). My application (K-Nearest Neighbor) requires that i make n*n blocks out of the data i have (the polygon), i.e. If i have a polygon (a road or a piece of land), i want a n*n square moving over it while avoiding intersection with edges and putting those n*n pixels into some variable. This problem would be a lot easier if i had all my shapes in the form of rectangles, but that unfortunately isn't the case. I might have something going diagonal, circular or just irregular.

  • What's the fastest way to approximate the period of data using Octave?

    - by John
    I have a set of data that is periodic (but not sinusoidal). I have a set of time values in one vector and a set of amplitudes in a second vector. I'd like to quickly approximate the period of the function. Any suggestions? Specifically, here's my current code. I'd like to approximate the period of the vector x(:,2) against the vector t. Ultimately, I'd like to do this for lots of initial conditions and calculate the period of each and plot the result. function xdot = f (x,t) xdot(1) =x(2); xdot(2) =-sin(x(1)); endfunction x0=[1;1.75]; #eventually, I'd like to try lots of values for x0(2) t = linspace (0, 50, 200); x = lsode ("f", x0, t) plot(x(:,1),x(:,2)); Thank you!

  • Why is my form triggering the wrong controller action?

    - by COCoach
    This form has multiple submit buttons, when clicked, it calls a simple JavaScript function to change the value of a hidden input (function is called "setHidden". This worked before, after some other not relevant code, it has ceased working. Essentially, the action it is supposed to call is never called, instead it seems to default back to a previous URL. The Form: <form action="/League/RemoveOwner" method="post"> <input type="hidden" value="1007" name="lid"/> <input type="hidden" value="0" id="index" name="index"/> <input type="image" src="../../Resources/Images/Delete.png" height="12" alt="Remove Owner" title="Remove Owner" onclick="setHidden('index', '1031')"/></a> coach<br /> </form> The Controller: [HttpPost] public ActionResult RemoveOwner(int id, string index) { //yada return PartialView(); } When clicking the image, it should call the remove owner controller, instead it calls the "View" controller: public ActionResult View(int id) { //yada return View(); }

  • Form validation with optional File Upload field callback

  • Correct way to use Drupal 7 Entities and Field API

    - by Martin Petts
    I'm trying to use Drupal 7's entities and field API to correctly build a new module. What I have been unable to understand from the documentation is the correct way to use the new API to create a 'content type' (not a node type) with a number of set fields, such as Body. I'm trying to set up the entity using hook_entity_info, then I believe I need to add the body field using field_create_instance, but I can't seem to get it to work. In mycontenttype.module: /** * Implements hook_entity_info(). */ function mycontenttype_entity_info() { $return = array( 'mycontenttype' => array( 'label' => t('My Content Type'), 'controller class' => 'MyContentTypeEntityController', 'base table' => 'content_type', 'uri callback' => 'content_type_uri', 'entity keys' => array( 'id' => 'cid', 'label' => 'title' ), 'bundles' => array( 'mycontenttype' => array( 'label' => 'My Content Type', 'admin' => array( 'path' => 'admin/contenttype', 'access arguments' => array('administer contenttype') ) ) ), 'fieldable' => true ) ); return $return; } /** * Implements hook_field_extra_fields(). */ function mycontenttype_field_extra_fields() { $return['mycontenttype']['mycontenttype'] = array( 'form' = array( 'body' = array( 'label' = 'Body', 'description' = t('Body content'), 'weight' = 0, ), ), ); return $return; } Then does this go in the .install file? function mycontenttype_install() { $field = array( 'field_name' => 'body', 'type' => 'text_with_summary', 'entity_types' => array('survey'), 'translatable' => TRUE, ); field_create_field($field); $instance = array( 'entity_type' => 'mycontenttype', 'field_name' => 'body', 'bundle' => 'mycontenttype', 'label' => 'Body', 'widget_type' => 'text_textarea_with_summary', 'settings' => array('display_summary' => TRUE), 'display' => array( 'default' => array( 'label' => 'hidden', 'type' => 'text_default', ), 'teaser' => array( 'label' => 'hidden', 'type' => 'text_summary_or_trimmed', ) ) ); field_create_instance($instance); }

  • What's void *userData exactly?

    - by mystify
    In a C function declaration, I have seen this parameter definition: void *userData so, what exactly is that? My guess: the void says it can be anything arbitrary, or even nothing. Almost similar to id of objective-c. It just allows to pass in whatever data structure you like. The star in front of userData says, that the argument must be passed in by reference. So when using this stuff in the function body, typically it must be casted and dereferenced. So if I pass in an pointer to SomeClass instance, I would get that like this: SomeClass *myObj = (SomeClass*)userData; In the case I had nothing special to pass along, I would provide NULL as argument. Are my assumptions correct? Or did I get something wrong?
