  • Magento - Programmatically added products don't show up

    - by Lucasmus
    I am trying to import products using a custom made import profile. Here I set some values on the product and then save it, like this: $product = Mage::getModel('catalog/product'); $data = array(); // Inbetween I fill $data with some values $product->addData($data); $product->save(); However, the products do show up in the admin, but do not show up on the frontend (I did add them to categories). The odd thing is, they do appear on the frontend once I open them in the admin and save them again (without modifying anything). Am I forgetting something, or some value that is somehow set by that action? I tried to rebuild all indices in the backend and to clear the cache, but this does not work, contrary to Magento API: Rebuild Indexes after adding new products.

  • Split string into smaller part with constrain [PHP RegEx HTML]

    - by Sadi
    Hello, I need to split long string into a array with following constrains: Each part will have a limited number of character (e.g. not more than 8000 character) Each part can contain multiple sentences (delimited by . [full stop]) but never a partial sentences. Except if the last part of the string (as last part may not have any full stop. The string may contain HTML tags. But the tag can not be divided as ( to ). That means HTML tag should be intact. But starting tag and ending tag can be stay on different segment/chunk. I think regular expression with preg_split can do it. Would please help me with the proper RegEx. Thank you Sadi

  • iPhone: TabBarController as second level of Navigation Controller

    - by Nebs
    I'm new to iphone development. I've read tutorials about implementing a tab bar controller on the window (eg as the main controller for the app). But how can I create a tab bar controller as a 'standalone' UIViewController that can be called by a navigation bar controller? Basically my navigation bar controller has an array of UIViewControllers that it displays in the table and then loads the appropriate view/controller when a user selects an item. Now I want one of these loaded views/controllers to be a tab bar controller. How can I do this? I'm not sure how to create a tab bar controller on its own without having an outlet/instance in the application delegate. Hope that made sense. Thanks.

  • How to always return a set number of records when using find_related_tags with acts-as-taggable-on

    - by hadees
    I'm using the acts-as-taggable-on gem and I need to use find_related_tags on my survey model to get back 3 surveys every time. In the event there aren't always 3 related I need to pick how ever many are related plus some random ones to get to 3. Additionally I have a method I wrote called completed_survey_ids which return an array of survey_ids that shouldn't be used because the user has already completed them. Also there is a rare case that there won't be enough surveys because the user has completed them all so in that event it is okay to return less surveys then requested. I did write a named_scope to handle getting rid of the completed_survey_ids that I think works named_scope :not, lambda { |survey_ids| {:conditions => "id NOT IN (#{survey_ids.join(',')})" } }

  • How to get the stream of a public Facebook fanpage in php?

    - by Bundy
    Hi, I want to display my public fanpage feed onto my website via the Facebook API without requiring a login. I'm doing this require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get('',$app_id,'0','0','','','','','')); But I get this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'user id parameter or session key required' in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php:3065 Stack trace: #0 includes/classes/facebook-platform/php/facebookapi_php5_restlib.php(1915): FacebookRestClient->call_method('facebook.stream...', Array) #1 facebook/api.php(12): FacebookRestClient->stream_get('', 13156929019, '0', '0', 30, '', '', '', '') #2 {main} thrown in includes/classes/facebook-platform/php/facebookapi_php5_restlib.php on line 3065 Then I figured, because of 'user id parameter or session key required', to add my user id to the call require_once('../includes/classes/facebook-platform/php/facebook.php'); $fb = new Facebook($api_key, $secret); $fb->api_client->stream_get(502945616,13156929019,$app_id,'0','0','','','','','')); But then I got this error Fatal error: Uncaught exception 'FacebookRestClientException' with message 'Session key invalid or no longer valid' I'm totally clueless :)

  • Finding many local max in an image (using MatLab)

    - by wenh42
    How do you go about figuring our multiple max in a 2D image where the max aren't necessarily all the same height? I have found that the imregionalmax(), imextendedmax(), and findpeaks() functions aren't necessarily that helpful because they give many local max that are really just maxes within the background noise. I tried bw=arrayimdilate(array,[1 1 1; 1 0 1; 1 1 1]) but that also is kind of limited for the same reasons (same thing with expanding the matrix that it uses). I'd definitely appreciate some help..

  • Adding "selected" into option from matching variable. PHP

    - by Dolan
    I have $country which stores the 2 letter country code of a user. US for example. <select id="countries"> <option value="US">United States</option> <option value="EN">England</option> <option value="AU">Australia</option> <option value="CA">Canada</option> etc. </select> What's the best practice to add "selected" to the option of the users country code? I'm against adding a million if's. Also note, the countries are harcoded in HTML, so no array. :(

  • how can I declare a value deep in an object tree using variable properties in javascript

    - by joshs
    I am trying to have a javascript object tree behave like a php associative array in the following way. var key1 = 'a'; var key2 = 'b'; var key3 = 'c'; var obj[key1][key2][key3] = 'd'; However, in javascript I believe you need to define each property/object pair individually, forming deeper leaves. Something like: var obj[key1] = {}; var obj[key1][key2] = {}; ... Is there a way to simplify or shorten this script? Thanks

  • In CouchDB, how to get documents limited on value in related document? In terms of SQL, how to make WHERE on JOINed table

    - by amorfis
    Crossposting from [email protected] Assume we have two kind of documents in CouchDB. Person and Car: Person: _id firstname surname position salary Car: _id person_id reg_number brand So there is one to many relationship. One person can have many cars. I can construct map function to get every person and his/her car next to each other. In such case key is array [person.id, 0] and [car.person_id, 1]. What I can't do, is limiting this view to owners of specific brand only, e.g. if I need salaries of owners of Ferrari.

  • Best way to insert items from a Derived class's constructor into a Base class's private std::vector?

    - by Will
    I have these classes: class Base { ... private: std::vector<X> v; }; class Derived { Derived(X*, int n); } where the constructor of Derived is passed an array of item Xs, which I need to insert into my vector v in the Base class. (X is a smart pointer) Currently I see two ways to do this: 1) Create a function in Base: InsertItem(X*) that will insert an item into the vector. 2) Create a vector in Derived that contains the full list, then get it into Base by moving the entire vector. I dont see any advantages to #2, but was wondering if #1 was a good solution, or if there are better ways to do this. Thanks!

  • Is this a good way to identify the type of a javascript object?

    - by FK82
    Apparently neither instanceof nor typeof deliver in terms of correctly identifying the type of every javascript object. I have come up with this function and I'm looking for some feedback: function getType() { var input = arguments[0] ; var types = ["String","Array","Object","Function","HTML"] ; //!! of the top of my head for(var n=0; n < types.length; n++) { if( input.constructor.toString().indexOf( types[n] ) != -1) { document.write( types[n] ) ; } } } Thanks for reading!

  • PHP exec() not executing batch files

    - by Andreas Bonini
    I tried googling for this issue and found many people with the same problem but no solution. $result = exec("C:\\Ruby191\\bin\\lessc.bat less\\$file", $output); Here result is an empty string and output an empty array. Same thing with: $result = exec("cmd /c C:\\Ruby191\\bin\\lessc.bat less\\$file", $output); I am sure the path is correct; I am sure exec() is enabled. I tried exec, shell_exec, system and none work. lessc is less CSS.

  • C++ initializing constants and inheritance

    - by pingvinus
    I want to initialize constant in child-class, instead of base class. And use it to get rid of dynamic memory allocation (I know array sizes already, and there will be a few child-classes with different constants). So I try: class A { public: const int x; A() : x(0) {} A(int x) : x(x) {} void f() { double y[this->x]; } }; class B : A { B() : A(2) {} }; Pretty simple, but compiler says: error C2057: expected constant expression How can I say to compiler, that it is really a constant?

  • HTML + javascript mouse over, mouseout, onclick not working in firefox.

    - by lucky
    Hello Everyone, My question is to get onMouseover,onMouseout,onMousedown,onClick on a table row. For which i am calling javascript userdefined functions. onMouseover --- Background color should change. onMouseout --- Reset to original color onClick --- First column checkbox/radio button should be set and background color should change onMousedown --- background color should change. My code in html is:- <tr onMouseOver="hover(this)" onMouseOut="hover_out(this)" onMouseDown="get_first_state(this)" onClick="checkit(this)" > and the methods in javascripts are:- var first_state = false; var oldcol = '#ffffff'; var oldcol_cellarray = new Array(); function hover(element) { if (! element) element = this; while (element.tagName != 'TR') { element = element.parentNode; } if (element.style.fontWeight != 'bold') { for (var i = 0; i<element.cells.length; i++) { if (element.cells[i].className != "no_hover") { oldcol_cellarray[i] = element.cells[i].style.backgroundColor; element.cells[i].style.backgroundColor='#e6f6f6'; } } } } // ----------------------------------------------------------------------------------------------- function hover_out(element) { if (! element) element = this; while (element.tagName != 'TR') { element = element.parentNode; } if (element.style.fontWeight != 'bold') { for (var i = 0; i<element.cells.length; i++) { if (element.cells[i].className != "no_hover") { if (typeof oldcol_cellarray != undefined) { element.cells[i].style.backgroundColor=oldcol_cellarray[i]; } else { element.cells[i].style.backgroundColor='#ffffff'; } //var oldcol_cellarray = new Array(); } } } } // ----------------------------------------------------------------------------------------------- function get_first_state(element) { while (element.tagName != 'TR') { element = element.parentNode; } first_state = element.cells[0].firstChild.checked; } // ----------------------------------------------------------------------------------------------- function checkit (element) { while (element.tagName != 'TR') { element = element.parentNode; } if (element.cells[0].firstChild.type == 'radio') { var typ = 0; } else if (element.cells[0].firstChild.type == 'checkbox') { typ = 1; } if (element.cells[0].firstChild.checked == true && typ == 1) { if (element.cells[0].firstChild.checked == first_state) { element.cells[0].firstChild.checked = false; } set_rowstyle(element, element.cells[0].firstChild.checked); } else { if (typ == 0 || element.cells[0].firstChild.checked == first_state) { element.cells[0].firstChild.checked = true; } set_rowstyle(element, element.cells[0].firstChild.checked); } if (typ == 0) { var table = element.parentNode; if (table.tagName != "TABLE") { table = table.parentNode; } if (table.tagName == "TABLE") { table=table.tBodies[0].rows; //var table = document.getElementById("js_tb").tBodies[0].rows; for (var i = 1; i< table.length; i++) { if (table[i].cells[0].firstChild.checked == true && table[i] != element) { table[i].cells[0].firstChild.checked = false; } if (table[i].cells[0].firstChild.checked == false) { set_rowstyle(table[i], false); } } } } } function set_rowstyle(r, on) { if (on == true) { for (var i =0; i < r.cells.length; i++) { r.style.fontWeight = 'bold'; r.cells[i].style.backgroundColor = '#f2f2c2'; } } else { for ( i =0; i < r.cells.length; i++) { r.style.fontWeight = 'normal'; r.cells[i].style.backgroundColor = '#ffffff'; } } } It is working as expected in IE. But coming to firefox i am surprised on seeing the output after so much of coding. In Firefox:-- onMouseOver is working as expected. color change of that particular row. onClick -- Setting the background color permenantly..eventhough i do onmouseover on different rows. the clicked previous row color is not reset to white. -- not as expected onclick on 2 rows..the background of both the rows is set..Only the latest row color should be set. other rows that are selected before should be set back..not as expected i.e if i click on all the rows..background color of everything is changed... Eventhough i click on the row. First column i.e radio button or checkbox is not set.. Please help me to solve this issue in firefox. Do let me know where my code needs to be changed... Thanks in advance!!

  • Split String in C# without delimiter (sort of)

    - by Zach
    Hi, I want to split a string in C#.NET that looks like this: string Letters = "hello"; and put each letter (h, e, l, l, o) into an array or ArrayList. I have no idea what to use as the delimiter in String.Split(delimiter). I can do it if the original string has commas (or anything else): string Letters = "H,e,l,l,o"; string[] AllLettersArray = Letters.Split(",".ToCharArray()); But I have no idea what to use in a case with (supposedly) no delimiter. Is there a special character like Environment.Newline? Thanks.
