• PHP header redirection does not reload <iframe> in IE

  - by Marco Demaio

  When displaying data from DB usually I'm in this situation I'm in page A.php that shows data from DB, user performs some action (like edit/delete etc) and page B.php is loaded to perform the action, once page B performed the action, it redirects browser to page A, page A is auto reloaded during step (3) therefor it shows an updated situation of the data In order to make page B to redirect to page A i use a simple PHP header("Location: " . "A.php", TRUE, 302); This works well in all situations, except when pages A.php is displaied into an <iframe>: in such a case it does not reload (step 4 does not get done). This seems to happen only in IE7 (don't know about IE8), it works perfectly on FF/Safari. And only when using an <iframe>, if page A.php is not in <iframe> it gest refreshed also in IE7. In order to solve this I simply added a couple of headers in page A.php to set it to not be cached: header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past But I was curious if you might have experienced the same issue too in the past, and if you good give me some advice about this?

• Can a page opt out of IIS 7 compression?

  - by Glen Little

  My pages are automatically being compressed by IIS7 with GZIP. That is great... but, for one particular page, I need to stream it to the user, using Response.Flush() when needed. But when the output is being compressed, the IIS server seems to collect all my output until the page is done before compressing and sending it to the client. That nullifies my attempt to Flush the content out to the user. Is there a way that I can have this one page opt out of the compression? One possible option I've determined that if I manually set the content type to one that does not match the IIS configuration at c:\windows\system32\inetsrv\config\applicationhost.config, then IIS will not compress it. Eg. Response.ContentType = "x-text/html". This works okay with IE8, as it falls back to display the HTML. But Firefox will ask the user what to do with the unknown file type. This could work, if there was another Mime Type I could use that browsers would accept as HTML, that is not matched in the applicationhost.config. For reference, these are the mime types that will be compressed: <add mimeType="text/*" enabled="true" /> <add mimeType="message/*" enabled="true" /> <add mimeType="application/x-javascript" enabled="true" /> <add mimeType="application/atom+xml" enabled="true" /> <add mimeType="application/xaml+xml" enabled="true" /> Others options? Are there other options to opt out of compression?

• MVC View Model Intellesense / Compile error

  - by Marty Trenouth

  I have one Library with my ORM and am working with a MVC Application. I have a problem where the pages won't compile because the Views can't see the Model's properties (which are inherited from lower level base classes). They system throws a compile error saying that 'object' does not contain a definition for 'ID' and no extension method 'ID' accepting a first argument of type 'object' could be found (are you missing a using directive or an assembly reference?) implying that the View is not seeing the model. In the Controller I have full access to the Model and have check the Inherits from portion of the view to validate the correct type is being passed. Controller: return View(new TeraViral_Blog()); View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<com.models.TeraViral_Blog>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Index2 </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Index2</h2> <fieldset> <legend>Fields</legend> <p> ID: <%= Html.Encode(Model.ID) %> </p> </fieldset> </asp:Content>

• What is the equivalent to Master Views from ASP.NET in PHP?

  - by KingNestor

  I'm used to working in ASP.NET / ASP.NET MVC and now for class I have to make a PHP website. What is the equivalent to Master Views from ASP.NET in the PHP world? Ideally I would like to be able to define a page layout with something like: Master.php <html> <head> <title>My WebSite</title> <?php headcontent?> </head> <body> <?php bodycontent?> </body> </html> and then have my other PHP pages inherit from Master, so I can insert into those predefined places. Is this possible in PHP? Right now I have the top half of my page defined as "Header.html" and the bottom half is "footer.html" and I include_once both of them on each page I create. However, this isn't ideal for when I want to be able to insert into multiple places on my master page such as being able to insert content into the head. Can someone skilled in PHP point me in the right direction?

• 'send' button error 401

• How can I get all content within <table></table> tags using a regex?

  - by Bob Dylan

  So I'm writing an application that will do a little screen scrapping. All the pages (about 1000 or so) contain this line: <table border="0" cellspacing="3"> <tr><td>First rows stuff</td></tr> <tr> <td> The data I want is in here <br /> and it's seperated by these annoying <br /> 's. No id's, classes, or even a single <p> tag. Just a bunch of <br /> tags. </td> </tr> </table> So I just need to get the data within the 2nd row out. How can I do this? Should I use a regex or something else?

• New record may be written twice in clusterd index structure

  - by Cupidvogel

  As per the article at Microsoft, under the Test 1: INSERT Performance section, it is written that For the table with the clustered index, only a single write operation is required since the leaf nodes of the clustered index are data pages (as explained in the section Clustered Indexes and Heaps), whereas for the table with the nonclustered index, two write operations are required—one for the entry into the index B-tree and another for the insert of the data itself. I don't think that is necessarily true. Clustered Indexes are implemented through B+ tree structures, right? If you look at at this article, which gives a simple example of inserting into a B+ tree, we can see that when 8 is initially inserted, it is written only once, but then when 5 comes in, it is written to the root node as well (thus written twice, albeit not initially at the time of insertion). Also when 8 comes in next, it is written twice, once at the root and then at the leaf. So won't it be correct to say, that the number of rewrites in case of a clustered index is much less compared to a NIC structure (where it must occur every time), instead of saying that rewrite doesn't occur in CI at all?

• XML and HTML = need help using HTML code

  - by whitstone86

  I'm converting my static HTML site to a dynamic PHP/XML-driven one. This is my current code: <div class="divider"></div> <div class="main" style="width: 552px;"> <div class="time">00:00</div> <div class="show"><h3><b>Radio Show</b></h3> <p>Description</p></div> <div class="footer"></div> </div> and my XML file: <?xml version="1.0"?> <show> <showdesc> <divider1></divider1> <divmain></divmain> <airtime></airtime> <presenter></presenter> <showinfo></showinfo> <divfooter></divfooter> </showdesc> which is the above HTML, that I'm trying to get into the XML file. I don't know how to get it to get the info in, I can display a simple XML page, as suggested here: http://www.kirupa.com/web/xml_php_parse_intermediate.htm but I am trying to in PHP get this to display what's in the XML pages or display this output: "Sorry. No schedule page is available" if the XML is blank, as above. Anyone able to help me fix this? I've tried and tried but it's baffling me... Thanks.

• How can you make a PHP application require a key to work?

  - by jasondavis

  About 4 years ago I used a php product called amember pro, it is a membership script which has plugins for lie 30 different payment processors, it was an easy way to set up an automated membership site where users would pay a payment and get access to a certain area. The script used ioncube http://www.ioncube.com/sa_encoder.php to prevent non-paying users from using the script, it requered that you register the domain that the script would be used on, you were then given a key to enter into the file that would make the system/script work. Now I am wanting to know how to do such a task, I know ioncube encoder just makes it hard to see the code, in the script I mention, they would just have a small section at the tp of 1 of the included pages that was encrypted and without that part of the code it would break and in addition if the owner of the script did not put you domain in the list and give you a valid key it would not work, also if you tried to use the script on a different domain it would not work. I realize that somewhere in the encrypted code that is must of sent you key to there server and checked that it was valid for the domain name it is on, or possibly it did not even do that, maybe the key would just verify that it matched the domain the script was on, that more likely what it did. Here is where the real question is, How would you make a script require the portion that is encrypted? If I made a script and had a small encrypted part at the top, it would seem a user would be able to easily just remove the encrypted part and figure out what the non encrypted part is doing and fix it to work. Any ideas?

• Classic ASP application-wide initializations and object caching

  - by slack3r

  In classic ASP (which I am forced to use), I have a few factory functions, that is, functions that return classes. I use JScript. In one include file I use these factory functions to create some classes that are used throughout the application. This include file is included with the #include directive in all pages. These factory functions do some "heavy lifting" and I don't want them to be executed on every page load. So, to make this clear I have something like this: // factory.inc function make_class(arg1, arg2) { function klass() { //... } // ... Some heavy stuff return klass; } // init.inc, included everywhere <!-- #include FILE="factory.inc" --> // ... MyClass1 = make_class(myarg01, myarg02); MyClass2 = make_class(myarg11, myarg12); //... How can I achieve the same effect without calling make_class on every page load? I know that I can't cache the classes in the Application object I can't use the Application_OnStart hook in Global.asa I could probably create a scripting component, but I really don't want to do that So, is there something else I can do? Maybe some way to achieve caching of these classes, which are really objects in JScript. PS: [further clarification] In the above code "heavy stuff" is not so heavy, but I just want to know if there's a way to avoid it being executed all the time. It reads database meta information, builds a table of the primary keys in the database and another table that resolves strings to classes, etc.

• Formating Date in Freemarker to say "Today", "Yesterday", etc.

  - by egervari

  Is there a way in freemarker to compare dates to test if the date is today or yesterday... or do I have to write code in Java to do these tests? I basically want to do this: <#------------------------------------------------------------------------------ formatDate -------------------------------------------------------------------------------> <#macro formatDate date showTime=true> <#if date??> <span class="Date"> <#if date?is_today> Today <#elseif date?is_yesterday> Yesterday <#else> ${date?date} </#if> </span> <#if showTime> <span class="Time">${date?time}</span> </#if> </#if> </#macro> EDIT: My best guess to implement this is to pass "today" and "yesterday" into the model for the pages that use this function and then compare the date values against these 2 objects in the model. I am out of out of options, but I'd rather not have to do this for every page that uses this macro. Any other options that are nicer? <#if date??> <span class="Date"> <#if date?date?string.short == today?date?string.short> Today <#elseif date?date?string.short == yesterday?date?string.short> Yesterday <#else> ${date?date} </#if> </span> <#if showTime> <span class="Time">${date?time}</span> </#if> </#if>

• Drupal advanced ACLs for "untrusted" administrators

  - by redShadow

  I have a multi-site Drupal-6 installation containing websites of different customers. On each site, there is an "administrator" role that includes mainly the customer's account. We want to give as many permissions as possible to this privileged user, but this could bring to security leaks using just the Drupal Core permissions management system. The main thing to avoid is the customer account being able to run PHP code on the server (that would be like being logged on the server as the www-data user.. sounds really bad). To avoid that, it is not sufficient to deny PHP code evaluation for the role. Since the administrator role must have permissions to manage users, he could also change the password of the user #1 and login in the site as superadmin. The second goal would be to deny also some "confusing" administrative pages (such as module selection) but not others (such as site informations configuration, or theme selection, etc.) I found the User One module that seems to fix the first problem, but I have no idea on how to solve the second one. I found some modules around, but no-one seems to fit.. it seems like the most ACLs are thought to protect the content, and not the site itself, as if the site administrator would always be the server owner itself..

• Prepare community images for google image search indexing

  - by Vittorio Vittori

  Hi, I'm trying to understand how can I do to let my site be reachable from google image search spiders. I like how last.fm solution, and I thought to use a technique like his staff do to let google find artists images on their pages. When I'm looking for an artist and I search it on google image search, as often as not I find an image from last.fm artists page, I make an example: If I search the band Pure Reason Revolution It brings me here, the artist's image page http://www.last.fm/music/Pure+Reason+Revolution/+images/4284073 Now if I take a look to the image file, i can see it's named: http://userserve-ak.last.fm/serve/500/4284073/Pure+Reason+Revolution+4.jpg so if I try to undertand how the service works I can try to say: http://userserve-ak.last.fm/serve/ the server who serve the images 500/ the selected size for the image 4284073/ the image id for database Pure+Reason+Revolution+4.jpg the image name I thought it's difficult to think the real filename for the image is Pure+Reason+Revolution+4.jpg for image overwrite problems when an user upload it, in fact if I digit: http://userserve-ak.last.fm/serve/500/4284073.jpg I probably find the real image location and filename With this tecnique the image is highly reachable from search engines and easily archived. My question is, does exist some guide or tutorial to approach on this kind of tecniques, or something similar?

• How can I access a parent DOM from an iframe on a different domain?

  - by Dexter

  I have a website and my domain is registered through Network Solutions. I'm using their Web Forwarding feature which allows me to "mask" my domain so that when a user visits http://lucasmccoy.com they are actually seeing http://lucasmccoy.comlu.com/ through an HTML frame. The advantages of this are that the address bar still shows http://lucasmccoy.com/. The disadvantages are that I cannot directly edit the HTML page in which the frame is owned. For example, I cannot change the page title or favicon. I have tried doing it like so: $(function() { parent.document.title = 'Lucas McCoy'; }); But of course this gives me a JavaScript error: Unsafe JavaScript attempt to access frame with URL http://lucasmccoy.com/ from frame with URL http://lucasmccoy.comlu.com/. Domains, protocols and ports must match. I looked at this question attempting to do the same thing except the OP has access to the other pages HTML whereas I do not. Is there anyway in JavaScript/jQuery to make a cross-domain request to the DOM when you don't have access to that domain? Or is this something browsers just will not let happen for security reasons.

• What makes good web form styling for business applications?

  - by ProfK

  Styling forms (form elements) is something that even Eric Meyer prefers to avoid. However, most business forms, and that is where styling is at issue; 'contact us' forms are easy to style, put window estate at a premium, with more 'document level' (e.g. invoice) fields, plus 'detail level' (e.g. invoice line) fields. Factors I often find at play are: At my minimum, at least two horizontally adjacent fieldsets are required. In applications vs. public web pages, fixed positioning vs fluid layout is often better. Quantity of content is important, vs. exaggerated readability. Users know the system, and cues etc. take a back seat. In light of factors like these, is there any available guidence for styling web form based applications? Are there any CSS or JavaScript frameworks that would make my quest to style these applications better than Visual Studios still pathetic 'Auto-format' (what drugs were those people on? I will never take them.)

• Apache ReWriteEngine throwing 500 Internal Server Error for too many internal redirects... why?!?!?!

  - by Stephen G

  I'm trying to implement a new ReWrite rule on my local dev machine. I have 13 rules set up already, and all work fine (even as of this writing). However, for some reason the newest one is throwing me 500 Internal Server Errors. The ReWrite rule is: RewriteRule stuff/public_html/vault/mystuff/view/(.*) /stuff/public_html/vault/mystuff/view/index.php?stuff=$1 RewriteRule stuff/public_html/vault/mystuff/view/(.*)/ /stuff/public_html/vault/mystuff/view/index.php?stuff=$1 Checked my apache logs and got this: [Thu Jan 13 22:07:43 2011] [error] [client ::1] mod_rewrite: maximum number of internal redirects reached. Assuming configuration error. Use 'RewriteOptions MaxRedirects' to increase the limit if neccessary., referer: http://localhost:8888/stuff/public_html/vault/mystuff/all/index.php?curr=7 On the script I am trying to redirect to view/index.php?stuff=$1, there is nothing that even remotely resembles a redirect of any kind. I do have a very, very basic session verifier being called at the top of the landing script, which is as follows: //Start session session_start(); //Check whether the session variable SESS_MEMBER_ID is present or not if(!isset($_SESSION['SESS_MEMBER_ID']) || (trim($_SESSION['SESS_MEMBER_ID']) == '')) { header("location: ".$root_http.""); exit(); } However, when I access the page directly, it acts as it should, and there is no redirect. All of my other ReWrite rules and their corresponding landing pages are set up the exact same way. This is blowing my mind. Any help, PLEASE!?

• Validate HAML from ActiveRecord: scope/controller/helpers for link_to etc?

  - by Chris Boyle

  I like HAML. So much, in fact, that in my first Rails app, which is the usual blog/CMS thing, I want to render the body of my Page model using HAML. So here is app/views/pages/_body.html.haml: .entry-content= Haml::Engine.new(body, :format => :html5).render ...and it works (yay, recursion). What I'd like to do is validate the HAML in the body when creating or updating a Page. I can almost do that, but I'm stuck on the scope argument to render. I have this in app/models/page.rb: validates_each :body do |record, attr, value| begin Haml::Engine.new(value, :format => :html5).render(record) rescue Exception => e record.errors.add attr, "line #{(e.respond_to? :line) && e.line || 'unknown'}: #{e.message}" end end You can see I'm passing record, which is a Page, but even that doesn't have a controller, and in particular doesn't have any helpers like link_to, so as soon as a Page uses any of that it's going to fail to validate even when it would actually render just fine. So I guess I need a controller as scope for this, but accessing that from here in the model (where the validator is) is a big MVC no-no, and as such I don't think Rails gives me a way to do it. (I mean, I suppose I could stash a controller in some singleton somewhere or something, but... excuse me while I throw up.) What's the least ugly way to properly validate HAML in an ActiveRecord validator?

• Trying to update a google visualization using jquery

  - by Mark in A2

  I'm relatively inexperienced, so please bear with me. I'm developing a simple dashboard using the Google visualization API. I'm developing in vb.net. I have the Annotated Timeline, the Intensity Map, and a set of tables on my apsx. What I am trying to do is update the Intensity Map and tables based on the date range the user selects using the Annotated Timeline tool. I was hoping to update only these visualizations without doing a full page load. Apparently, a great way to do this is to separate the visualizations into self-contained aspx pages and use jQuery to "load" them into a div. I say apparently, as this is not working. When I try to update an aspx containing a Google visualization using jQuery, I get the message "Loading data from www.google.com..." in the browser and it just runs continuously and never returns. I ran this by an experienced developer and he was stumped, but thought must be a conflict between the google API and jQuery. Any tips, advice, alternative solutions are greatly appreciated! Thanks, Mark in Ann Arbor

• How can someone with no experience learn how to program?

  - by Mugatu

  A friend and I have been coming up with website ideas for a couple years, mostly just jotting them down whenever we come up with a good, useful idea when browsing the web. For the past 6 months we've hired a couple different programmers to make a couple of the sites for us, but have been disappointed with how it's gone. Been too slow and too many miscommunications for our liking. So like the saying goes if you want something done right do it yourself, we're going to do it ourselves. I know nothing about programming, I've never written a line of code in my life. I consider myself very good with math and about as logical as you can get, but I have zero real-life programming knowledge. The sites we want to make are all pretty 'Web 2.0'ish', meaning user-generated content, commenting on posts, pages that change on the fly, etc. So here are some of my questions for anyone who's been there before: Is there a language you'd recommend learning first? Something that is a good indicator how most other languages work? What web programming languages do you recommend learning first based on popularity both now and the future. I don't want to learn a language that's going to be outdated by the time I'm an expert at it. Any specific books you'd recommend? Any general advice you'd give to someone literally starting at square zero for coding who plans on being in it for the long haul?

• Selenium: Can i test if a page loaded a flash app (ie a swf) properly?

  hi all. I'm writing some selenium tests (in rspec for a rails app).

• Creating WPF components in background thread

  - by mizipzor

  Im working on a reporting system, a series of DocumentPage are to be created through a DocumentPaginator. These documents include a number of WPF components that are to be instantiated so the paginator includes the correct things when later sent to the XpsDocumentWriter (which in turn is sent to the actual printer). My problem now is that the DocumentPage instances take quite a while to create (enough for Windows to mark the application as frozen) so I tried to create them in a background thread, which is problematic since WPF expects the attributes on them to be set from the GUI thread. I would also like to have a progress bar showing up, indicating how many pages have been created so far. Thus, it looks like Im trying to get two things to happen in parallell on the GUI. The problem is hard to explain and Im really not sure how to tackle it. In short: Create a series of DocumentPage's. These include WPF components These are to be created on a background thread, or use some other trick so the application isnt frozen. After each page is created, a WPF ProgressBar should be updated. If there is no decent way to do this, alternate solutions and approaches are more than welcome.

• Has anyone setup tomcat to run virtual hosts using mod_jk

  I work in OSX primarily with mostly PHP. Normally I work locally using MAMP and virtual hosts setup in my httpd.conf so that I can point a browser to http://some-project and have as many projects as I need setup. We have a project coming up where we need to serve JSP pages and I would like to set up my local apache server to serve only JSP files to Tomcat and everything else to MAMP using the same virtual hosts setup in: ~/applications/MAMP/conf/apache/httpd.conf So far I have: Successfully installed Tomcat Placed mod_jd.so in ~/applications/MAMP/Library/modules/mod_jk.so Added the module by placing: LoadModule jk_module modules/mod_jk.so in ~/applications/MAMP/conf/apache/httpd.conf Created /Library/Tomcat/Home/conf/jk/workers.properties and added the following lines: workers.tomcat_home=/Library/Tomcat workers.java_home=/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Home ps=/ worker.list=ajp12, ajp13 worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp12.type=ajp13 worker.ajp13.mount=/*.jsp added the following lines: JkWorkersFile /Library/Tomcat/Home/conf/workers.properties JkLogFile /Library/Tomcat/Home/logs/mod_jk.log JkLogLevel debug to ~/applications/MAMP/conf/apache/httpd.conf I cannot start my MAMP however when these last two lines are present in my httpd.conf. Does anyone work like this? Any tips? Any clear ideas of what I'm doing wrong?

• Why is PHP discriminating between .php and .abc extensions for caching?

  - by Sam

  There seems to be a problem between how PHP engine handles identical files that differ only in their file extension. Problem: "An If-Modified-Since conditional request returned the full content unchanged." Also, I measured that the .php extension loads much faster than identitcal twin with .xxx extension even though the file contents are identical, and they differ only in their file extension. "HTTP allows clients to make conditional requests to see if a copy that they hold is still valid. Since this response has a Last-Modified header, clients should be able to use an If-Modified-Since request header for validation. RED has done this and found that the resource sends a full response even though it hadn't changed, indicating that it doesn't support Last-Modified validation." homepage ending with .php exact same file, but ending .ast Given: A home.php file is copied as home.xxx and this extension is added to htaccess to recognize it as a PHP file. The .php file listen to the php.ini where freshness is set to 3 hrs, the non .php files have to listen to htaccess where freshness is set to 2 hrs according to: AddType application/x-httpd-php .php .ast .abc .xxx .etc <IfModule mod_headers.c> ExpiresActive On ExpiresDefault M2419200 Header unset ETag FileETag None Header unset Pragma Header set Cache-Control "max-age=2419200" ##### DYNAMIC PAGES <FilesMatch "\\.(ast|php|abc|xxx)$"> ExpiresDefault M7200 Header set Cache-Control "public, max-age=7200" </FilesMatch> </IfModule> So far so good and everything loads, except, the non-php file doesn't cache properly, or it does cache well but doesn't validate well, to be more specific. See images enclosed. Only the non-php file extension causes the error and loads slower. The entire page.php loads faster as somehow all the elements in there then load properly from cache, while the page.abc has the full request returned while it ought to be cached, meaning the entire page is slower. Bottom line: What should be changed, in order eliminate the If-Modified-Since conditional request returning the full content unchanged?
