  • A F# tail-recursive question

    - by ksharp
    Recently, I'm learning F#. I try to solve problem in different ways. Like this: (* [0;1;2;3;4;5;6;7;8] -> [(0,1,2);(3,4,5);(6,7,8)] *) //head-recursive let rec toTriplet_v1 list= match list with | a::b::c::t -> (a,b,c)::(toTriplet_v1 t) | _ -> [] //tail-recursive let toTriplet_v2 list= let rec loop lst acc= match lst with | a::b::c::t -> loop t ((a,b,c)::acc) | _ -> acc loop list [] //tail-recursive(???) let toTriplet_v3 list= let rec loop lst accfun= match lst with | a::b::c::t -> loop t (fun ls -> accfun ((a,b,c)::ls)) | _ -> accfun [] loop list (fun x -> x) let funs = [toTriplet_v1; toTriplet_v2; toTriplet_v3]; funs |> List.map (fun x -> x [0..8]) |> List.iteri (fun i x -> printfn "V%d : %A" (i+1) x) I thought the results of V2 and V3 should be the same. But, I get the result below: V1 : [(0, 1, 2); (3, 4, 5); (6, 7, 8)] V2 : [(6, 7, 8); (3, 4, 5); (0, 1, 2)] V3 : [(0, 1, 2); (3, 4, 5); (6, 7, 8)] Why the results of V2 and V3 are different?

  • PHP Dom problem, how to insert html code in a particular div

    - by sala_7
    I am trying to replace the html code inside the div 'resultsContainer' with the html of $response. The result of my unsuccessful code is that the contents of 'resultsContainer' remain and the html of $response shows up on screen as text rather than being parsed as html. Finally, I would like to inject the content of $response inside 'resultContainer' without having to create any new div, I need this: <div id='resultsContainer'>Html inside $response here...</div> and NOT THIS: <div id='resultsContainer'><div>Html inside $response here...</div></div> // Set Config libxml_use_internal_errors(true); $doc = new DomDocument(); $doc->strictErrorChecking = false; $doc->validateOnParse = true; // load the html page $app = file_get_contents('index.php'); $doc->loadHTML($app); // get the dynamic content $response = file_get_contents('search.php'.$query); $response = utf8_decode($response); // add dynamic content to corresponding div $node = $doc->createElement('div', $response); $doc->getElementById('resultsContainer')->appendChild($node); // echo html snapshot echo $doc->saveHTML();

  • Html image link, not working

    - by Anders Metnik
    Hey I'm doing some testing while learning js + html5 and other web/mobile frameworks. I have a problem with one of my picture links, which I also need to change the picture dynamically and the target(hopefully). But it won't work. HTML: <div data-role="content" id="firstPageContent"> <p>I'm first in the source order so I'm shown as the page.</p> <p>View internal page called <a href="#second">second</a></p> <a href = "#second" id="mapLink" name="mapLink"><img id="mapLinkImage" alt="a map which links to the mapPage" src="images/main_header.png"/></a> <Button id="loadButton" onClick="load()"/> </div><!-- /content --> js: importScripts(dataManager.js); var mapLink=second; function load(){ alert('called'); document.getElementById('mapLinkImage').src="images/store.map.png"; document.getElementById('mapLink').href = "http://google.com"; } problem: It ain't showing the image as a link, just as a plain image. i think this will work now.

  • Omit Properties from WebControl Serialization

    - by Laramie
    I have to serialize several objects inheriting from WebControl for database storage. These include several unecessary (to me) properties that I would prefer to omit from serialization. For example BackColor, BorderColor, etc. Here is an example of an XML serialization of one of my controls inheriting from WebControl. <Control xsi:type="SerializePanel"> <ID>grCont</ID> <Controls /> <BackColor /> <BorderColor /> <BorderWidth /> <CssClass>grActVid bwText</CssClass> <ForeColor /> <Height /> <Width /> ... </Control> I have been trying to create a common base class for my controls that inherits from WebControl and uses the "xxxSpecified" trick to selectively choose not to serialize certain properties. For example to ignore an empty BorderColor property, I'd expect [XmlIgnore] public bool BorderColorSpecified() { return !base.BorderColor.IsEmpty; } to work, but it's never called during serialization. I've also tried it in the class to be serialized as well as the base class. Since the classes themselves might change, I'd prefer not to have to create a custom serializer. Any ideas?

  • Writing a printList method for a Scheme interpreter in C

    - by Rehan Rasool
    I am new to C and working on making an interpreter for Scheme. I am trying to get a suitable printList method to traverse through the structure. The program takes in an input like: (a (b c)) and internally represent it as: [""][ ][ ]--> [""][ ][/] | | ["A"][/][/] [""][ ][ ]--> [""][ ][/] | | ["B"][/][/] ["C"][/][/] Right now, I just want the program to take in the input, make the appropriate cell structure internally and print out the cell structure, thereby getting (a (b c)) at the end. Here is my struct: typedef struct conscell *List; struct conscell { char symbol; struct conscell *first; struct conscell *rest; }; void printList(char token[20]){ List current = S_Expression(token, 0); printf("("); printf("First Value? %c \n", current->first->symbol); printf("Second value? %c \n", current->rest->first->first->symbol); printf("Third value? %c \n", current->rest->first->rest->first->symbol); printf(")"); } In the main method, I get the first token and call: printList(token); I tested the values again for the sublists and I think it is working. However, I will need a method to traverse through the whole structure. Please look at my printList code again. The print calls are what I have to type, to manually get the (a (b c)) list values. So I get this output: First value? a First value? b First value? c It is what I want, but I want a method to do it using a loop, no matter how complex the structure is, also adding brackets where appropriate, so in the end, I should get: (a (b c)) which is the same as the input. Can anyone please help me with this?

  • ruby on rails implement search with auto complete

    - by user429400
    I've implemented a search box that searches the "Illnesses" table and the "symptoms" table in my DB. Now I want to add auto-complete to the search box. I've created a new controller called "auto_complete_controller" which returns the auto complete data. I'm just not sure how to combine the search functionality and the auto complete functionality: I want the "index" action in my search controller to return the search results, and the "index" action in my auto_complete controller to return the auto_complete data. Please guide me how to fix my html syntax and what to write in the js.coffee file. I'm using rails 3.x with the jquery UI for auto-complete, I prefer a server side solution, and this is my current code: main_page/index.html.erb: <p> <b>Syptoms / Illnesses</b> <%= form_tag search_path, :method => 'get' do %> <p> <%= text_field_tag :search, params[:search] %> <br/> <%= submit_tag "Search", :name => nil %> </p> <% end %> </p> auto_complete_controller.rb: class AutoCompleteController < ApplicationController def index @results = Illness.order(:name).where("name like ?", "%#{params[:term]}%") + Symptom.order(:name).where("name like ?", "%#{params[:term]}%") render json: @results.map(&:name) end end search_controller.rb: class SearchController < ApplicationController def index @results = Illness.search(params[:search]) + Symptom.search(params[:search]) respond_to do |format| format.html # index.html.erb format.json { render json: @results } end end end Thanks, Li

  • Creating rapid function overloads in C++

  • Is it possible that two requests at the same time double this code? (prevent double database entry)

    - by loostro
    1) The controller code (Symfony2 framework): $em = $this->getDoctrine()->getEntityManager(); // get latest toplist $last = $em->getRepository('RadioToplistBundle:Toplist')->findOneBy( array('number' => 'DESC') ); // get current year and week of the year $week = date('W'); $year = date('Y'); // if: // [case 1]: $last is null, meaning there are no toplists in the database // [case 2]: $last->getYear() or $last->getWeek() do not match current // year and week number, meaning that there are toplists in the // database, but not for current week // then: // create new toplist entity (for current week of current year) // else: // do nothing (return) if($last && $last->getYear() == $year && $last->getWeek() == $week) return; else { $new = new Toplist(); $new->setYear($year); $new->setWeek($week); $em->persist($new); $em->flush(); } This code is executed with each request to view toplist results (frontend) or list of toplists (backend). Anytime someone wants to access the toplist we first check if we should create a new toplist entity (for new week). 2) The question is: Is it possible that: User A goes to mydomain.com/toplist at 00:00:01 on Monday - the code should generate new entity the server slows down and it takes him 3 seconds to execute the code so new toplist entity is saved to database at 00:00:04 on Monday User B goes to mydomain.com/toplist at 00:00:02 on Monday at 00:00:02 there the toplist is not yet saved in database, thus UserB's request triggers the code to create another toplist entity And so.. after a few seconds we have 2 toplist entities for current week. Is this possible? How should I prevent this?

  • Struts logic:iterate input field

    - by camilos
    I currently have the following code and the data is displayed fine. <logic:iterate name="myList" id="product" indexId="iteration" type="com.mycompany.MyBean"> <tr> <td> <bean:write name="product" property="weight"/> </td> <td> <bean:write name="product" property="sku"/> </td> <td> <bean:write name="product" property="quantity"/> </td> </tr> </logic:iterate> But now I need to make the "quantity" part modifiable. The user should be able to update that field, press submit and when its sent to the server, "myList" should automatically update with the new quantities. I've tried searching for help on this but all I keep finding is examples on how to display data only, not modify it. Any help would be appreciated.

  • Protocol specification in XML

    - by Mathijs
    Is there a way to specify a packet-based protocol in XML, so (de)serialization can happen automatically? The context is as follows. I have a device that communicates through a serial port. It sends and receives a byte stream consisting of 'packets'. A packet is a collection of elementary data types and (sometimes) other packets. Some elements of packets are conditional; their inclusion depends on earlier elements. I have a C# application that communicates with this device. Naturally, I don't want to work on a byte-level throughout my application; I want to separate the protocol from my application code. Therefore I need to translate the byte stream to structures (classes). Currently I have implemented the protocol in C# by defining a class for each packet. These classes define the order and type of elements for each packet. Making class members conditional is difficult, so protocol information ends up in functions. I imagine XML that looks like this (note that my experience designing XML is limited): <packet> <field name="Author" type="int32" /> <field name="Nickname" type="bytes" size="4"> <condition type="range"> <field>Author</field> <min>3</min> <max>6</min> </condition> </field> </packet> .NET has something called a 'binary serializer', but I don't think that's what I'm looking for. Is there a way to separate protocol and code, even if packets 'include' other packets and have conditional elements?

  • Div appearing outside its parent, bizarre sizing problems...

    - by SLC
    I have a list, which is going to be a menu. I want to position it absolutely at the very top of the page. My code looks like this: <div id="sitenavmenu"> <div id="sitenavmenu-content"> <ul id="sitenavmenu-content-menu"> <li>Register</li> <li><%: Html.ActionLink("About", "About", "Home")%></li> <li>Contact Us</li> </ul> </div> </div> My CSS looks like this: #sitenavmenu { position:absolute; margin-left:300px; top:2px; width:500px; } #sitenavmenu-content-menu li { list-style-type:none; display:inline; padding-right:5px; font-size:small; } The problem I have is, if I don't position it absolutely, it looks fine. As soon as I position it absolutely (as it is shown above), the sitenavmenu div changes size, and although it shifts to the top, the sitenavmenu-content div appears below it. There is no other CSS as I have only just started, and I have checked padding etc. and everything is zero. I just can't figure out why it's not working, and I don't want to hack it. Edit: It's something to do with the height of #sitenavmenu. If I leave it, then the sitenav-content ends up horizontally centered in it, although #sitenavmenu is much taller. If I make them both the same size, so they should sit on top of each other, then the #sitenavmenu-content sits below.

  • Background Image Overlapped Problem with jQuery

    - by Devyn
    Hi, Here is my working page. I attached buttons to white bishop and you can move around but left images are overlapped by right images. I think the problem is with CSS. The brief structure is here. <script> $(document).ready(function(){ $('#top').click(function(){ $('#p81').animate({top: "-=64px"}, 100); }); </script> <style> div.chess_board{ height: 512px; position: relative; width: 512px; } div.chess_square{ height:64px; position: absolute; width:64px; } div.chess_square.white { background: none repeat scroll 0 0 #ffffff; } . . . div.chess_piece{ background-image: url("sprite.png"); height: 64px; width: 64px; position: absolute; } div.chess_piece.bishot.white{ background-position: -64px 0; } </style> <div class="chess_board"> <div id="b81" class="chess_square white" style="top: 448px; left: 64px;"> <div class="chess_square_inner"></div> <div id="p81" class="chess_piece bishot white"></div> </div> </div> <input type="button" id="top" value="top" />

  • Why doesn't line-height work on FF/3.5.8(Mac)?

    - by Znarkus
    I can't get line-height on a text input to work on Firefox 3.5.8/(Mac). Works flawlessly on: IE6 IE7 IE8 FF3.6/PC FF3.6/Mac Safari Test code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>asd</title> <link rel="stylesheet" type="text/css" href="http://yui.yahooapis.com/2.8.0r4/build/reset/reset-min.css" /> </head> <body> <input type="text" value="Hello" style="line-height:50px;height:50px;font-size:16px;" /> <input type="text" value="Hello" style="padding:17px 0;font-size:16px;" /> </body> </html> Is there an alternate solution or any idea how to fix this? Edit: Updated the test code, to compare line-height vs. padding technique. Padding works on all above browsers except IE8. Whaat? I can't test on FF/3.5.8 anymore, could someone please report the result from this browser on any plattform? I'm now thinking this is a Firefox 3.5.8 issue, plattform independent.

  • Display Consistent Value of an Item using MVVM and WPF

    - by Blake Blackwell
    In my list view control (or any other WPF control that will fit the situation), I would like to have one TextBlock that stays consistent for all items while another TextBlock that changes based on the value in the ObservableCollection. Here is how my code is currently laid out: XAML <ListView ItemsSource="{Binding Path=MyItems, Mode=TwoWay}"> <ListView.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock x:Name="StrVal" Text="{Binding StrVal}" /> <TextBlock x:Name="ConstVal" Text="{Binding MyVM.ConstVal}" /> </StackPanel> </DataTemplate> </ListView.ItemTemplate> </ListView> Model public class MyItem { public string StrVal { get; set; } } ViewModel public class MyVM { public MyVM() { ObservableCollection<MyItem> myItems = new ObservableCollection<MyItem>(); for (int i = 0 ; i < 10; i++) myItems.Add(new MyItem { StrVal = i.ToString()}); MyItems = myItems; ConstVal = "1"; } public string ConstVal { get; set; } public ObservableCollection<MyItem> MyItems { get; set; } } Code Behind this.DataContext = new MyVM(); The StrVal property repeats correctly in the ListView, but the ConstVal TextBlock does not show the ConstVal that is contained in the VM. I would guess that this is because the ItemsSource of the ListView is MyItems and I can't reference other variables outside of what is contained in the MyItems. My question is: How do I get ConstVal to show the value in the ViewModel for all listviewitems that will be controlled by the Observable Collection of MyItems.

  • Using DisplayFor inside a display template

    - by Oenotria
    I've created a htmlhelper extension to reduce the amount of repetitive markup when creating forms: public static MvcHtmlString RenderField<TModel, TValue>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TValue>> expression) { return htmlHelper.DisplayFor(expression, "formfield"); } The idea being that inside my views I can just write @Html.RenderField(x=>x.MyFieldName) and it will print the label and the field's content with the appropriate div tags in place already. Inside the displaytemplates folder I have created formfield.cshtml containing the following: <div class="display-group"> <div class="display-label"> @Html.LabelFor(x => x) </div> <div class="display-field"> @Html.DisplayFor(x => x) </div> </div> Unfortunately it doesn't appear that it is possible to nest DisplayFor inside a display template (it doesn't render anything). I don't want to just using @Model because then I won't get checkboxes for boolean values, calendar controls for dates etc. Is there a good way around this?

  • In Silverlight, what structures, aside of the ListBox, can be used for binding?

    - by Aidenn
    I need to simply provide the content of a property to a custom User Control in Silverlight. My control is something like this: <UserControl x:Class="SilverlightApplication.Header" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWidth="300" d:DesignHeight="120"> <Grid x:Name="Header_Layout"> <StackPanel x:Name="hiHeaderContent" Width="Auto" Margin="73,8,8,8"> <TextBlock x:Name="User:" Text="{Binding name}" /> </StackPanel> </Grid> I try to use this User Control from another control where I try to pass the parameter "name" to the previous UserControl ("Header"). I don't need to create a "ListBox" as I will only have 1 header, so I try to avoid doing: <ListBox x:Name="HeaderListBox" Grid.Row="0"> <ListBox.ItemTemplate> <DataTemplate> <SilverlightApplication:Header/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> in order to send the "User" account using: HeaderListBox.ItemsSource = name; Is there any other structure I can use instead of the ListBox to pass the parameter just once? It won't be a list, it's just a header... Thank you!

  • How to iterate properly across a const set?

    - by Jared
    I'm working on a program that's supposed to represent a graph. My issue is in my printAdjacencyList function. Basically, I have a Graph ADT that has a member variable "nodes", which is a map of the nodes of that graph. Each Node has a set of Edge* to the edges it is connected to. I'm trying to iterate across each node in the graph and each edge of a node. void MyGraph::printAdjacencyList() { std::map<std::string, MyNode*>::iterator mit; std::set<MyEdge*>::iterator sit; for (mit = nodes.begin(); mit != nodes.end(); mit++ ) { std::cout << mit->first << ": {"; const std::set<MyEdge*> edges = mit->second->getEdges(); for (sit = edges.begin(); sit != edges.end(); sit++) { std::pair<MyNode*, MyNode*> edgeNodes = *sit->getEndpoints(); } } std::cout << " }" << std::endl; } getEdges is declared as: const std::set<MyEdge*>& getEdges() { return edges; }; and get Endpoints is declared as: const std::pair<MyNode*, MyNode*>& getEndpoints() { return nodes; }; The compiler error I'm getting is: MyGraph.cpp:63: error: request for member `getEndpoints' in `*(&sit)->std::_Rb_tree_const_iterator<_Tp>::operator-> [with _Tp = MyEdge*]()', which is of non-class type `MyEdge* const' MyGraph.cpp:63: warning: unused variable 'edgeNodes' I have figured out that this probably means I'm misusing const somewhere, but I can't figure out where for the life of me. Any information would be appreciated. Thanks!

  • Pulling $_GET data and creating multidimensional array using loop

    - by Chris J
    I'm creating a checkout for customers and the data about what's in their cart is being sent to a page (for just now) via $_GET. I want to extract that data and then populate a multidimensional array with it using a loop. Here's how I'm naming the data: $itemCount = $_GET['itemCount']; $i = 1; while ($i <= $itemCount) { ${'item_name_'.$i} = $_GET["item_name_{$i}"]; ${'item_quantity_'.$i} = $_GET["item_quantity_{$i}"]; ${'item_price_'.$i} = $_GET["item_price_{$i}"]; //echo "<br />Name: " .${'item_name_'.$i}. " - Quantity: " .${'item_quantity_'.$i}. " - Price: ".${'item_price_'.$i}; $i++; } From here I'd like to create a multidimensional array like such: Array ( [Item_1] => Array ( [item_name] => Shoe [item_quantity] => 2 [item_price] => 40.00 ) [Item_2] => Array ( [item_name] => Bag [item_quantity] => 1 [item_price] => 60.00 ) [Item_3] => Array ( [item_name] => Parrot [item_quantity] => 4 [item_price] => 90.00 ) . . . ) What I'd like to know is if there is a way I can create this array in the existing while loop? I'm aware of being able to add data to an array like $data = [] after delacring an empty array but the actual syntax eludes me. Maybe I'm completely off the right track and there is a better way of doing it? Thanks

The structure is as follows: $mail = new PHPMailer; $mail->IsSMTP(); // Set mailer to use SMTP $mail->Host = 'myserver.com'; // Specify main and backup server $mail->SMTPAuth = true; // Enable SMTP authentication $mail->Username = '[email protected]'; // SMTP username $mail->Password = 'user123'; // SMTP password $mail->SMTPSecure = 'pass123'; It seems to me to be a bit of a security hole having the mailbox credentials in plain view. So I thought I might put these in an external file outside of the web root. My question is how would I then assign the $mail object these values. I of course no how to use include and/or requires... would it simple be a case of.... $mail->IsSMTP(); // Set mailer to use SMTP $mail->Host = 'myserver.com'; // Specify main and backup server $mail->SMTPAuth = true; // Enable SMTP authentication includes '../locationOutsideWebroot/emailCredntials.php'; $mail->SMTPSecure = 'pass123'; Then emailCredentails.php: <?php $mail->Username = '[email protected]'; $mail->Password = 'user123'; ?> Would this be sufficient and secure enough? Thanks, Alan.

  • RoR ActiveRecord f.select nil method error

    - by sellis6688
    Whenever I use an f.select statement to determine assignment_id(or student_id), and I should get a validation error, I get this error instead of the validation message: You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.collect Extracted source (around line #11): 8: </p> 9: <p> 10: <%= f.label 'Assignment:' %><br /> 11: <%= f.select(:assignment_id, @assignments.collect {|p| [p.ass_num, p.id]})%> 12: </p> 13: <p> 14: <%= f.label 'First Student:' %><br /> My grades model: class Grade < ActiveRecord::Base has_and_belongs_to_many :students belongs_to :assignment validates_presence_of :score, :assignment_id, :student_id validates_numericality_of :score, :greater_than_or_equal_to => 0, :less_than_or_equal_to => 100, :allow_nil => true validates_uniqueness_of :student_id, :scope => :assignment_id end If I use a text_field, I don't get the error... but there's far too many students for that. Neither @assignments nor @students are nil. Any suggestions?

  • Using innerHTML to add ordered list fails in IE

    - by Matt
    I'm using the following Javascript code to populate a DIV with an ordered list: // send script back in split list var scriptList = script.split("\n"); var finalScript = "<ol>\n"; var count = 0; while(scriptList.length >= count) { if((scriptList[count]=="") || (scriptList[count] == undefined)) { count ++; continue; } finalScript = finalScript + "<li>" + scriptList[count] + "</li>\n"; count ++; } finalScript = finalScript + "</ol>"; scriptingDiv.innerHTML = finalScript; In firefox, if i look in the DOM using Firebug, this correctly translates to the following and correctly displays an ordered list. <ol> <li>This is the first item in the list</li> <li>This is the second item in the list</li> </ol> In IE, it displays as if the </li> tags are <br /> tags and ignores all the other tags, like this: This is the first item in the list This is the second item in the list Do I need to dynamically add the ordered list to the DOM for this to work? As opposed to just setting the html code in the div using .innerHTML? TIA

  • How to refactor models without breaking WPF views?

    - by Tim Murphy
    I've just started learning WPF and like the power of databinding it presents; that is ignoring the complexity and confusion for a noob. My concern is how do you safely refactor your models/viewmodels without breaking the views that use them? Take the following snippet of a view for example: <Grid> <ListView ItemsSource="{Binding Contacts}"> <ListView.View> <GridView> <GridViewColumn Header="First Name" DisplayMemberBinding="{Binding Path=FirstName}"/> <GridViewColumn Header="Last Name" DisplayMemberBinding="{Binding Path=FirstName}"/> <GridViewColumn Header="DOB" DisplayMemberBinding="{Binding Path=DateOfBirth}"/> <GridViewColumn Header="# Pets" DisplayMemberBinding="{Binding Path=NumberOfPets}"/> <GridViewColumn Header="Male" DisplayMemberBinding="{Binding Path=IsMale}"/> </GridView> </ListView.View> </ListView> </Grid> The list is bound to the Contacts property, IList(Of Contact), of the windows DataSource and each of the properties for a Contact is bound to a GridViewColumn. Now if I change the name of the NumberOfPets property in the Contact model to PetCount the view will break. How do I prevent the view breaking?

  • Break up PHP Pagination links

    - by Rabbott
    I have the following method that creates and returns markup for my pagination links in PHP. public function getPaginationLinks($options) { if($options['total_pages'] > 1) { $markup = '<div class="pagination">'; if($options['page'] > 1) { $markup .= '<a href="?page=' . ($options['page'] - 1) . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">< prev</a>'; } for($i = 1; $i <= $options['total_pages']; $i++) { if($options['page'] != $i) { $markup .= '<a href="?page='. $i . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">' . $i . '</a>'; } else { $markup .= '<span class="current">' . $i . '</span>'; } } if($options['page'] < $options['total_pages']) { $markup .= '<a href="?page=' . ($options['page'] + 1) . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">next ></a>'; } $markup .= '</div>'; return $markup; } else { return false; } } I just recently discovered (to my surprise) that i had reached 70+ pages which means that there are now 70+ links showing up at the bottom.. I'm wondering if someone can help me break this up.. I'm not sure how most pagination works as far as showing the numbers if im on say.. page 30, ideas?
