• Show wordpress posts outside of the blog

  - by way2project

  I have two wordpress blogs on my site and now I want to show the posts of categories of both blogs on the home page. I am using the following code. <?php require($_SERVER['DOCUMENT_ROOT'] . '/projects/wp-load.php'); query_posts('cat=9& showposts=8'); if (have_posts()) : while (have_posts()) : the_post(); ?> <ul><li> <a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php $shorttitle4 = substr(the_title('','',FALSE),0,25)."..."; echo $shorttitle4; ?></a> </li></ul> <?php endwhile; else: echo "no posts"; endif; ?> <?php wp_reset_query(); ?> One of my blogs is placed in the "projects" folder and another one is placed in "technology folder". but this code is showing the posts only from projects blogs if I changed the folder in as "technology" in the above code. I think this is because of wp-load.php file. Can you help me? Thanks

• Making a jQuery plugin to feed Tumblr to site

  - by tylorreimer

  I have some experience with PHP and a little with JS but I'm far from anything proficient. I'm trying to make a jQuery plugin for my site that I can call in my HTML via something like this: $('.new').tumble({username: "tylor", count: 9}); Which would basically put the Tumblr list the code should make into the DIV with class 'new' in this case. Here is my code so far; the problem seems to be how to get it to pick up class/id from the original call (in the HTML) and use that in the jQuery. Here's the code so far: (function($) { $.fn.tumble = function(options){ var settings = $.extend({ username: null, // [string or array] required to get url for tumblr account count: 3, // [integer] how many posts to display? }, options); //url construction var url = "http://" + settings.username + ".tumblr.com"; var jsonurl = url + "/api/read/json?num=" + settings.count + "&callback=?"; $.getJSON(jsonurl, function(data) { var items = []; $.each(data.posts, function(id, url) { // Goes over each post in the JSON document retrieved from data URL var url = this.url; // Just assigns a variable to the url to avoid constantly writing "this.whatever" var photourl = this['photo-url-250']; // photo-url-xxx needs to be called this way due to integers in the name items.push('<li><a href="' + url + '">' + photourl + '</a></li>'); }); $('<ul/>', { // Creates an empty list html: items.join('') // Takes the values in the item array and puts 'em together }).appendTo('.new'); // I don't want this to have the class set in the jQuery itself }); //end json }; })( jQuery ); Any help you can lend would be wonderful. Thank you

• Rails database relationships

  - by Danny McClelland

  Hi Everyone, I have three models that I want to interact with each other. Kase, Person and and Company. I have (I think) setup the relationships correctly: class Kase < ActiveRecord::Base #HAS ONE COMPANY has_one :company #HAS MANY PERSONS has_many :persons class Person < ActiveRecord::Base belongs_to :company class Company < ActiveRecord::Base has_many :persons def to_s; companyname; end I have put the select field on the create new Kase view, and the create new Person view as follows: <li>Company<span><%= f.select :company_id, Company.all %> </span></li> All of the above successfully shows a drop down menu dynamically populated with the company names within Companies. What I am trying to do is display the contact of the Company record within the kase and person show.html.erb. For example, If I have a company called "Acme, Inc." and create a new Kase called "Random Case" and choose within the create new case page "Acme, Inc." from the companies drop down menu. I would then want to display "Acme, Inc" along with "Acme, Inc. Mobile" etc. on the "Random Case" show.html.erb. I hope this makes sense to somebody! Thanks, Danny

• How to find the closest descendants (hat matches a selector) with jQuery?

  - by powerboy

  We can use closest(selector) to find the first ancestor element that matches the selector. It travels up the DOM tree until it finds a match for the selector. But what if I want to travels down the DOM tree until it finds a match for the selector? Is there any jQuery function for doing this? Give an example. For the DOM tree below, <div id="main"> <div> <ul><!-- I want to match this ul --> <li> <ul><!-- but not this ul --> </ul> </li> </ul> <ul><!-- and match this ul --> </ul> </div> </div> how to do something like $('#main').closestDescendants('ul')?

• gwtQuery's outerWidth(true) and IE8 not working without putting a delay

  - by Christopher

  I recently came across an odd behavior when trying to calculate the width (with margins) of an element using gwtQuery. The goal is to get the width (including padding, borders and margins) of a given element as a child of a certain parent. This parent may define specific CSS rules for some children so I clone it, add my element to this parent, call .outerWidth(true) to get the width and finally remove the clone from the parent. It works fine on Chrome, Firefox and IE 10, but randomly fails (outputs 0) on IE 8. However I noticed that if I put a "sleep" between the moment I add the element to the DOM and the moment I get the outer width, it always succeeds. I obviously don't want to keep that sleep. So my question is does anyone has any insights on how to work around this behavior or even a better way of achieving the same goal? Thank you! Here's a code snippet private Integer computeTabWidth(IsWidget tab) { GQuery $tab = $("<li></li>").append($(tab).clone()); $(containerPanel).append($tab); // IE 8 debug. sleep(100); Integer tabWidth = $tab.outerWidth(true); $tab.remove(); return tabWidth; } private void sleep(int i) { long time = new Date().getTime() + i; while (time > new Date().getTime()); }

• Displaying data from a linked table and displaying it as a list with HTML/PHP/MySQL

  - by user1672694

  I have three tables. students studentID | FirstName | LastName | Email | Form course CCode | Title courseenrolement courseenrolementid | studentID | ccode | complete | scode With the website, I have a page where I can view all the current enrolements and I wish to be able to view the list displaying the first name, surname and course title. I know I could do it with the following SQL (for the names): SELECT FirstName, LastName FROM student, courseenrolement WHERE courseenrolement.studentID = student.studentID But I am unsure how to get this to work using HTML/PHP. At present I only know how to display the studentID and CCode from the courseenrolement table using the following code: <ul> <?php foreach ($courseenrolements as $ce): ?> <li> <form action="" method="post"> <div> <?php htmlout($ce['studentID']); ?> <?php htmlout($ce['CCode']); ?> <input type="hidden" name="courseenrolementid" value="<?php echo $ce['courseenrolementid']; ?>"> <input type="submit" name="action" value="Edit"> <input type="submit" name="action" value="Delete"> </div> </form> </li> <?php endforeach; ?> </ul> which displays this: But I would like the names and course title. I managed to get it to show the names etc in the dropdown on the 'Add new' form, so I would assume it will be similar, but just unsure on how exactly. Thanks in advance

• Why there is no scoped locks for multiple mutexes in C++0x or Boost.Thread?

  - by Vicente Botet Escriba

  C++0x thread library or Boost.thread define non-member variadic template function that lock all lock avoiding dead lock. template <class L1, class L2, class... L3> void lock(L1&, L2&, L3&...); While this function avoid help to deadlock, the standard do not includes the associated scoped lock to write exception safe code. { std::lock(l1,l2); // do some thing // unlock li l2 exception safe } That means that we need to use other mechanism as try-catch block to make exception safe code or define our own scoped lock on multiple mutexes ourselves or even do that { std::lock(l1,l2); std::unique_lock lk1(l1, std::adopted); std::unique_lock lk2(l2, std::adopted); // do some thing // unlock li l2 on destruction of lk1 lk2 } Why the standard doesn't includes a scoped lock on multiple mutexes of the same type, as for example { std::array_unique_lock<std::mutex> lk(l1,l2); // do some thing // unlock l1 l2 on destruction of lk } or tuples of mutexes { std::tuple_unique_lock<std::mutex, std::recursive_mutex> lk(l1,l2); // do some thing // unlock l1 l2 on destruction of lk } Is there something wrong on the design?

• Search dir using wildcard string, return filename, and loop.

  - by Charlie Murphy

  Hello all, I'm having some problems, and looking for some help. I'm trying to create a photo gallery in javascript, that will be able to 'update' it's self automatically. I need to be able to search a directory, and grab a file with a specific prefix. I need to output the followng HTML code: <li><a href="images/resize_FILENAME.ext"><img src="images/thumb_FILENAME.ext"></a></li> The 'resize_' and 'thumb_' use a timestamp to identify, so they have the same ending, just a different prefix. So, for example, if I search the directory for an image with a prefix of 'resize_', I need to insert that into the a tag, and then remove the '_resize' prefix, and add the '_thumb' prefix for the img tag. I then need to be able to do that for each image in the directory. Any help would be greatly appreciated. Oh, I should add: I'm assuming php would be easiest for this, but if an alternative exists that would work too. I'm also using jQuery if javascript would be better.

• Working With Feeds and Lists

  - by Nathan Campos

  I'm using a ListView component to list up some informations at a RSS feed, but when the user clicks the row, I want to change into a detailed view of that RSS Item, so far I've done this: function parseFeed(feed) { var html = ""; for(var i = 0; i < feed.items.length && i < 5; i++) { var item = feed.items[i]; var title = item.title; html += "\n<li onClick='goDetailed()'>\n"; html += "<h3><a href='#' class='ui-link-inherit'>" + title + "</a></h3>\n"; html += "<p>" + item.description + "</p>\n"; html += "</li>"; } $("#dList").append(html); $("#dList").listview('refresh'); } function goDetailed() { $.mobile.changePage($('#detailedPage')); } One of my problems is that the Back button won't come back(it does nothing). My other question is how I can pass the item.title, item.description, item.link and item.updated of the selected row(feed item) to some <div data-role="content">'s at the detail page.

• How could I cache images that I'm pulling from a magento database through ajax?

  - by wes

  Here's script being called through ajax: <?php require_once '../app/Mage.php'; umask(0); /* not Mage::run(); */ Mage::app('default'); $cat_id = ($_POST['cat_id']) ? $_POST['cat_id'] : NULL; try { $category = new Mage_Catalog_Model_Category(); $category->load($cat_id); $collection = $category->getProductCollection(); $output = '<ul>'; foreach ($collection as $product) { $cProduct = Mage::getModel('catalog/product'); $cProduct->load($product->getId()); $output .= '<li><img id="'.$product->getId().'" src="' . (string)Mage::helper('catalog/image')->init($cProduct, 'small_image')->resize(75) . '" class="thumb" /></li>'; } $output .= '</ul>'; echo $output; } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } I'm just passing in the Category ID, which I've tacked onto the navigation links, then doing some work to eventually just pass back all product images in that category. I'm using this on a drag and drop build-a-bracelet type of application, and the amount of images returned is sometimes in the 500s. So it get's pretty held up during transmission, sometimes 10 seconds or so. I know I'd do good by caching them some way, just not sure how to go about it. Any help is much appreciated. Thanks. -Wes

• jQuery: AJAX call isn't updating page

  - by Cortopasta

  Thought I had a simple AJAX call using $.POST(), but apparently my function isn't firing, and nothing is updating :-/ Here is the call: $(".answerVerse ul li").click(function(){ var rank = $(this).removeClass("star_empty star_full star_highlight").attr("class"); var verse_id = $(this).parent().parent().find(".verseId").html(); var answer_id = $(this).parent().parent().find(".answerId").html(); var place = this; $.post("rank.php", { rank: rank, verse_id: verse_id, answer_id: answer_id },function(data){ $(place).parent().removeClass().addClass(data.newVerseRank); for (i=0;i<=5;i++) { $(".answerVerse ul."+i).each(function(){ $(".answerVerse ul."+i+" li."+i).prevAll().andSelf().removeClass("star_empty").addClass("star_full"); }); } }, "json"); }); And here is the PHP (rank.php) that it calls: require_once("dbcon.php"); $user = new user(); $user->updateVerseRank($_POST['verse_id'], $_POST['rank']); $user->getVerse($_POST['verse_id']); $user->getAnswer($_POST['answer_id']; $arr = array ('newVerseRank'=>htmlspecialchars(round($user->verse[3])),'newVerseVotes'=>htmlspecialchars(round($user->verse[4])),'newAnswerRank'=>htmlspecialchars($user->answer[3])); echo json_encode($arr); Why am I not updating the page?

• Is there an easier way to do Classic ASP "relative path"?

  - by Alex.Piechowski

  Right now, I'm having trouble. First of all I have a page, let's call it "http://blah.com/login". That obviously goes strait to "index.asp" A line of Main.asp: <!--#include file="resource/menu.asp"--> Page top includes all of what I need for my menu... so: Part of resource/menu.htm: <div id="colortab" class="ddcolortabs"> <ul> <li><a href="main.asp" title="Main" rel="dropmain"><span>Main</span></a></li> ... </ul> </div> <!--Main drop down menu --> <div id="dropmain" class="dropmenudiv_a"> <a href="main/announcements.asp">Announcements</a> <a href="main/contacts.asp">Contact Information</a> <a href="main/MeetingPlans.asp">Meeting Plan</a> <a href="main/photos.asp">Photo Gallery</a> <a href="main/events.asp">Upcoming Events</a> </div> Let's say I click on the "announcements" (http://blah.com/login/main/announcements.asp) link... Now I'm at the announcements page! But wait, I include the same menu file. Guess what happens: I get sent to "http://blah.com/login/main/main/announcements.asp Which doesn't exist... My solution: Make a menu_sub.asp include for any subpages. But wait a second... this WORKS, but it gets REALLY REALLY messy... What can I do to use just one main "menu.asp" instead of "menu_sub.asp"? using "/main/announcements.asp" WON'T be an option because this is a web application that will be on different directories per server. Any ideas? PLEASE

• Advise guidance on how to form this jQuery script for show/hide fade element

  - by Rick

  Hey guys.. I basically have several links on the left side of the screen and on the right is a preview window. Below the preview window is another box for the affiliate link code. So what I am trying to do is create an affiliate page where you choose the banner size on the left by clicking on the link and on the right you see it dynamically change to the banner size and the code changes accordingly as well. So far I have the following code and it works but it seems very very cumbersome and bloated. Can you see if I can trim this down? jQuery(".banner-style li").click(function() { jQuery(".banner-style li").removeClass("selected"); jQuery(this).addClass("selected"); var $banner = jQuery(this).attr("class"); $banner = $banner.replace(" selected",""); jQuery(".preview img").fadeOut('fast',function() { jQuery(".preview img").attr("src", "http://localhost/site/banners/"+$banner+".jpg") .fadeIn('slow'); }); jQuery(".code p").removeClass('hide').hide(); jQuery(".code p."+$banner).show(); }); Also to note the funny thing is in FF, when you click for the first to on any link, the original image on the right fades out and in real quick and then it loads the "clicked" image. This does not happen in other browsers...

• JQuery: how to use "delegate" instead of "live"?

  - by JacobD

  I've read countless articles how using the JQuery delegate is much more efficient than using the "live" event. As such, I'm having trouble converting my existing Live code to using Delegate. $("#tabs li:eq(0)").live('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').live('mouseover',function(){ // ...code }); When I replace the previous code with what I assume is more efficient delegate code, my page doesn't load. $("#tabs li:eq(0)").delegate('click',function(){ //...code }); $('#A > div.listing, #B > div.listing, #C > div.listing').delegate('mouseover',function(){ // ...code }); Any idea why my delegate code doesn't work? Also, any suggestions on how to make this more efficient? UPDATE: The think part of the problem is that, both "#tabs" and "#A, #B, #C" are't present on the web page at page load. Those attributes are dynamically inserted onto the page with an AJAX call. As such, does that mean I have to use live over delegate?

• Outstanding issues with jQuery.ajax() in IE8?

  - by RyanV

  I am loading feed-items into a ul using this jQuery .ajax() call, which I basically lifted from http://www.makemineatriple.com/2007/10/bbcnewsticker/ var timestamp = true; //set whether timestamp is displayed in $.ajax({ type: "GET", url: "sample-feed.xml", dataType: "xml", success: function(xml) { $(xml).find('item').each(function(){ var title = $(this).find('title').text(); var link = $(this).find('link').text(); if(title.length >=57){ title = title.substring(0,54) + "..."; } var addItem = '<li class="tickerTitle"><a href="'+link+'">'+title+'</a>'; if (Boolean(timestamp)== true){ var time = new Date(Date.parse($(this).find('pubDate').text())); addItem +='<span class="timestamp">' + makestamp(time) +'</span></li>'; } $('ul#news').append(addItem); }); It works in Chrome 4 and Firefox 3.6, but I load it up in IE8 and somehow the ajax call fails. I have tried to use IE8's Developer tools to see where exactly it fails, but I haven't been successful yet. So two questions Is there anything blatantly wrong with my ajax call here that could be preventing me from seeing it in IE where it works in FF/Chrome? Are there any special considerations I have to make for the Internet Explorer family of browsers with regards to this particular jQuery method? I've done some googling on this but nothing obvious is coming up. One other note: I am currently using jQuery 1.3.2 due to some legacy scripts on the same site. I did try loading 1.4.2 and it had the same results on IE8

• Saving a form using autocomplete instead of select field

  - by Jason Swett

  I have a form that looks like this: <%= form_for(@appointment) do |f| %> <% if @appointment.errors.any? %> <div id="error_explanation"> <h2><%= pluralize(@appointment.errors.count, "error") %> prohibited this appointment from being saved:</h2> <ul> <% @appointment.errors.full_messages.each do |msg| %> <li><%= msg %></li> <% end %> </ul> </div> <% end %> <%= f.fields_for @client do |client_form| %> <div class="field"> <%= client_form.label :name, "Client Name" %><br /> <%= client_form.text_field :name %> </div> <% end %> As you can see, the field for @client is a text field as opposed to select field. When I try to save my form, I get this error: Client(#23852094658120) expected, got ActiveSupport::HashWithIndifferentAccess(#23852079773520) That's not surprising. It seems to me that it was expecting a select field, which it could translate into a Client object, but instead it just got a string. I know I can do Client.find( :first, :conditions => { :name => params[:name] } ) to find a Client with that name, but how do I tell my form that that's what's going on?

• jQuery: Moving window (or FIFO) type DIV?

  - by Legend

  I have been trying to get this effect for a couple of hours now and I must admit I am failing at it. I am trying to construct a DIV that accepts a particular number of items (say 5), when the 6th item is added, the first item that was aded should be removed (first-in-first-out). The feel should have some kind of a fadeIn and fadeOut. Here's what I managed to write till now: ... //Create a ul element with id 'ulele' and add it to a div ... //Do an ajax call and when an element arrives Hash = ComputeHash(message) if(!$("#" + Hash).exists()) { var element = $("<li></li>").html(message).attr('id', Hash).prependTo("#ulele"); $("#" + Hash).hide().delay(10000 - 1000 * messageNumber).show("slow"); _this.prune("#ulele"); } ... prune: function(divid) { $("#" + divid).children().each( function(i, elemLi) { if(i >= maxMessages) $(this).delay(10000).hide("slow").delay(10000).remove(); } ); } I've tried a couple of variations but the final effect I am getting is not that of a FIFO. The elements disappear instantaneously despite the delay and hide("slow") calls. Anyone has a more straightforward approach?

• Dynamically including multiple files within php for image descriptions

(I have 77 individual text files with a phrase in each) but how do I tell it to call the files?

• Cleaner way of using modulus for columns

  I currently have a list (<ul>) of people that I have divided up into two columns. But after finishing the code for it I keept wondering if there is a more effective or clean way to do the same thing. echo "<table class='area_list'><tr>"; // Loop users within areas, divided up in 2 columns $count = count($areaArray); for($i=0 ; $i<$count ; $i++) { $uid = $areaArray[$i]; // get the modulus value + ceil for uneven numbers $rowCalc = ($i+1) % ceil($count/2); if ($rowCalc == 1) echo "<td><ul>"; // OUTPUT the actual list item echo "<li>{$users[$uid]->profile_lastname}</li>"; if ($rowCalc == 0 && $i!=0) echo "</ul></td>"; } echo "</tr></table>"; Any ideas of how to make this cleaner or do it in another way?

• Creating sublines on Joomla menu items

  - by ploughansen

  In my toplevel menu items, I would like to make a subline for each item. I don't think it's possible to do by default, byt YooTheme has done it in many of their templates. The menu output look like this <div class="moduletable_menu"> <ul id="mainmenu" class="menu"> <li class="active item1" id="current"> <a href="URL_HIDDEN"> <span>Services</span> </a> </li> </ul> This basically outputs a one line menu item like so: Services What I would like to do is have a menu item like this: Services Service x, Service y, Service z For reference, have a look at the main menu on the YooTheme demo page. The way YooTheme does this, is using two pipes (||) as a linebreak, so in the Joomla backend you type "Services||Service x, Service y, Service z" as the menu title, and then there must be some fancy javascript that breaks this title into two spans, ready to be styled using css. Does anyone know of an easy way to code this? Please note that I am looking to build this feature into a custom template (ie. non-yootheme). Also note that I am not using MooTools, but Jquery instead.

• jquery find() - how to exclude certain descendants, and their children?

  - by jammypeach

  I have markup similar to this: <div class='wrapper plugin'> //some content <div class='child-wrapper plugin'> //some more content <div> <ul> <li><div class='cliky'>clicky!</div></li> </ul> </div> </div> <div class='cliky'>clicky!</div> </div> I need to be able to select the first .clicky div only, not any .clicky divs inside a .plugin > .plugin div. The wrapper has .plugin class too - might seem counter-intuitive so another way to view it is this: I want to get the .clicky children of a given .plugin div, but not .plugin .plugin .clicky. Here's the problem - the depth of each .clicky element (or indeed, the number of them) is unknown and variable in relation to the wrappers. One could be immediately below the first wrapper, or inside 10 <ul>s. I've tried selectors like: $('.wrapper').find('.clicky').not('.plugin > .clicky'); But they still selected child .clicky. How would I be able to filter out .plugin and any children of .plugin from my selector before using find()?

  I'm having difficulty with Javascript instance variables. I'm trying to make an easy way to refresh the chat page, looking for new messages. The AJAX call supplies a mid, or the lowest message id to be returned. This allows the call to only ask for the most recent messages, instead of all of them. MessageRefresher.prototype._latest_mid; function MessageRefresher(latest_mid) { this._latest_mid = latest_mid; // it thinks `this` refers to the MessageRefresher object } MessageRefresher.prototype.refresh = function () { refreshMessages(this._latest_mid); // it thinks `this` refers to the window this._latest_mid++; } function refreshMessages(latest_mid) { $.getJSON('API/read_messages', { room_id: $.getUrlVar('key'), mid: latest_mid }, function (messages) { for (var i = 0; i < messages[0].length; i++) { var newChild = sprintf("<li>%s: %s</li>", messages[1][i], messages[0][i]); $("#messages").append(newChild); } }); var messageRefresher = new MessageRefresher(0); setInterval(messageRefresher.refresh, 1000); This results in all the messages being printed out, over and over again. I know it has other bugs, but the main issue I'm trying to work out right now is the use of the instance variable. Or is there another way I should be going about doing this?
