  • PHP DOMDocument Error Handling Problem

    - by Jon
    I'm having trouble trying to write an if statement for DOM that will check if $html is blank. However whenever the html page does end up blank, it just removes everything that would be below DOM (including what I had to check if it was blank). $html = file_get_contents("http://example.com/"); $dom = new DOMDocument; @$dom->loadHTML($html); $links = $dom->getElementById('dividhere')->getElementsByTagName('img'); foreach ($links as $link) { echo $link->getAttribute('src'); } All this does is grab an image url in the specified div, which works perfectly until the page is a blank html page. I've tried using SimpleHTMLDOM, which didn't work either (it didn't even fetch the image on working pages). Did I happen to miss something with this one or am I just missing something in both? include_once('simple_html_dom.php') $html = file_get_html("http://example.com/"); foreach($html->find('div[id="dividhere"]') as $div) { if(empty($div->src)) { continue; } echo $div->src; }

  • Adding an IList item to a particular index number

    - by Dr. Zim
    Our Client's database returns a set of prices in an array, but they sometimes don't include all prices, i.e., they have missing elements in their array. We return what we find as an IList, which works great when we retrieve content from the database. However, we are having difficulties setting the elements in the proper position in the array. Is it possible to create an IList then add an element at a particular position in the IList? var myList = new List<Model>(); var myModel = new Model(); myList[3] = myModel; // Something like what we would want to do

  • Mixing Transaction Script pattern with DDD/CQRS

    - by Herman
    Hi all, Here is the situation, in order to support our legacy system, we need to insert to a table whenever a user logs in. This is basically an CRUD operation, so it doesn't really make sense to create repository/entity/command/event for this since this doesn't tie to any business rules at all. The only benefit to create a CQRS command is that this database write can happen asynchronously under that model. Which is a better route to take? Use CQRS, and then call a stored proc. when handling that command? Just call database directly in the controller (I am using asp.net mvc)

  • URL naming conventions

    - by LookitsPuck
    So, this may be a can of worms. But I'm curious what your practices are? For example, let's say your website consists of the following needs (very basic): A landing page An information page for an event (static) A listing of places for that event (dynamic) An information page for each place With that said, how would you design your URLs? Typically, I'd do something like the following: www.domain.com/ - landing page [also accessible via www.domain.com/home] www.domain.com/event - event information page www.domain.com/places - listing of all places www.domain.com/places/{id} - place information page Now, here's a question. Just grammatically speaking, I have a hangup of referring to a given place in a url as being plural. Shouldn't it make more sense to go with this: www.domain.com/place/{id} as opposed to www.domain.com/places/{id} In some frameworks, you have a convention to follow (for example, ASP.NET MVC) by default. Yes, you can define custom routes to have /place/{id} route to the PlacesController. However, I'm just trying to keep this a bit abstract in discussion. With that being said, let's see for instance on another page of your site, you have a link, that when clicked, would open a modal popup populated with place information. Where you place that information? We could go with something like this: www.domain.com/ajax/places/{id} OR www.domain.com/places/{id} and serve based on the request header (that is, if requesting JSON, return JSON?}. Finally, for SEO reasons, typically I use a slug associated with a given resource. So, something like such: www.domain.com/ajax/places/{id}/london Where london is only there to add decoration to the link for SEO reasons. Is this sound? I ask all of these questions, because these are practices that I've been using for awhile, and I'd just like to see what other developers are doing or if I'm approaching things incorrectly. Thanks!

  • asp.net application install folder

    - by Maximilian Csuk
    Disclaimer: this is not a question about how to install asp.net or an application using it! Hi! I am pretty sure many of you have once installed some kind of forum, blog or CMS (mostly PHP powered applications). All of these contain a folder mostly named "install" where (after you copied the files to the webserver) point your browser to to complete the installation by entering for example database information (servername, username, password, ...). After that, most applications suggest that you delete this folder or at least change the permissions so nobody from the outside can access it anymore. Now to my question: how would you go about that in the asp.net world? I don't really like the "install folder"-approach and I thought there might be a different mechanism for .net/IIS. The person installing my application should be able to enter his database information as painless as possible, which should ultimatively be stored in the web.config file. If it makes a difference, I am using asp.net MVC. Thanks for your help!

  • Facebook graph API post to user's wall

    - by Lance
    I'm using the FB graph api to post content to the user's wall. I orginally tried using this method: $wall_post = array(array('message' => 'predicted the', 'name' => 'predicted the'), array('message' => $winning_team, 'name' => $winning_team, 'link' => 'http://www.sportannica.com/teams.php?team='.$winning_team.'&amp;year=2012'), array('message' => 'to beat the', 'name' => 'to beat the',), array('message' => $losing_team, 'name' => $losing_team, 'link' => 'http://www.sportannica.com/teams.php?team='.$losing_team.'&amp;year=2012'), array('message' => 'on '.$game_date.'', 'name' => 'on '.$game_date.''), array('picture' => 'http://www.sportannica.com/img/team_icons/current_season_logos/large/'.$winning_team.'.png')); $res = $facebook->api('/me/feed/', 'post', '$wall_post'); But, much to my surprise, you can't post multiple links to a users wall. So, now I'm using the graph api to post content to a user's wall much like the way spotify does. So, now I've figured out that I need to create custom actions and objects with the open graph dashboard. So, I've created the "predict" action and gave it permission to edit the object "game." So, now I have the code: $facebook = new Facebook(array( 'appId' => 'appID', 'secret' => 'SECRET', 'cookie' => true )); $access_token = $facebook->getAccessToken(); $user = $facebook->getUser(); if($user != 0) { curl -F 'access_token='$.access_token.'' \ -F 'away_team=New York Yankees' \ -F 'home_team=New York Mets' \ -F 'match=http://samples.ogp.me/413385652011237' \ 'https://graph.facebook.com/me/predict-edit-add:predict' } I keep getting an error reading: Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING Any ideas?

  • Help with Struts Action mapping

    - by nicotine
    I am having a problem with my struts application it is a class enrollment app and when the user clicks on a "show enrolled courses" button it is supposed to show the courses they are enrolled in but it shows nothing at the moment. Struts/Apache does not return any errors, it Just shows a blank page and I cannot figure out why. My action mapping in my struts-config: <action path="/showEnrolled" type="actions.ShowEnrolledAction" name="UserFormEnrolled" scope="request" validate="true" input="/students/StudentMenu.jsp"> <forward name="success" path="/students/enrolled.jsp"/> </action> My link to the jsp enrolled.jsp page: <li><html:form action="/showEnrolled"> <html:hidden property="id" value= "<%=request.getRemoteUser()%>"/> <html:submit value = "View Enrolled Classes"/> </html:form> </li> When I click the link I get nothing but my menu on the page. The text headings for the page are not even displayed.

  • How sophisticated should be DAL?

    - by Andrew Florko
    Basically, DAL (Data Access Layer) should provide simple CRUD (Create/Read/Update/Delete) methods but I always have a temptation to create more sophisticated methods in order to minimize database access roundtrips from Business Logic Layer. What do you think about following extensions to CRUD (most of them are OK I suppose): Read: GetById, GetByName, GetPaged, GetByFilter... e.t.c. methods Create: GetOrCreate methods (model entity is returned from DB or created if not found and returned), Create(lots-of-relations) instead of Create and multiple AssignTo methods calls Update: Merge methods (entities list are updated, created and deleted in one call) Delete: Delete(bool children) - optional children delete, Cleanup methods Where do you usually implement Entity Cache capabilities? DAL or BLL? (My choice is BLL, but I have seen DAL implementations also) Where is the boundary when you decide: this operation is too specific so I should implement it in Business Logic Layer as DAL multiple calls? I often found insufficient BLL operations that were implemented in dozen database roundtrips because developer was afraid to create a bit more sophisticated DAL. Thank you in advance!

  • Replace relative urls to absolute

    - by Rocky Singh
    I have the html source of a page in a form of string with me: <html> <head> <link rel="stylesheet" type="text/css" href="/css/all.css" /> </head> <body> <a href="/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> I want to convert all the relative paths to absolute. I want the output be: <html> <head> <link rel="stylesheet" type="text/css" href="http://mysite.com/css/all.css" /> </head> <body> <a href="http://mysite.com/test.aspx">Test</a> <a href="http://mysite.com">Test</a> <img src="http://mysite.com/images/test.jpg"/> <img src="http://mysite.com/images/test.jpg"/> </body> </html> Note: I want only the relative paths to be converted to absolute ones in that string. The absolute ones which are already in that string should not be touched, they are fine to me as they are already absolute. Can this be done by regex or other means?

  • Many to Many Association Tables - Is it customary to put additional columns in these tables?

    - by Randy Minder
    We've encountered the following situation in our database. We have table 'A' and table 'B' which have a M2M relationship. The association table is named 'AB' and contains a FK column to table 'A' and a FK column to table 'B'. Now we've identified a need to store additional data about this association. For example, a date when the association occurred, and who made the association etc. We've decided to put these additional columns in the 'AB' association table. However, something tells me this is frowned upon by database purists. On the other hand, it makes no sense to us to create yet an additional table to store this associated data. What's the prevailing thought on this?

  • Why Does Piping Binary Text to the Screen often Horck a Terminal

    - by Alan Storm
    Imaginary Situation: You’ve used mysqldump to create a backup of a mysql database. This database has columns that are blobs. That means your “text” dump files contains both strings and binary data (binary data stored as strings?) If you cat this file to the screen $ cat dump.mysql you’ll often get unexpected results. The terminal will start beeping, and then the output finishes scrolling by you’ll often have garbage chacters entered on your terminal as through you’d typed them, and sometimes your prompts and anything you type will be garbage characters. Why does this happen? Put another way, I think I’m looking for an overview of what’s actually happening when you store binary strings into a file, and when you cat those files, and when the results of the cat are reported to the terminal, and any other steps I’m missing.

  • Error in MySQL Workbench Forward Engineered Stored Procedures

    - by colithium
    I am using MySQL Workbench (5.1.18 OSS rev 4456) to forward engineer a SQL CREATE script. For every stored procedure, the automatic process outputs something like: DELIMITER // USE DB_Name// DB_Name// DROP procedure IF EXISTS `DB_Name`.`SP_Name` // USE DB_Name// DB_Name// CREATE PROCEDURE `DB_Name`.`SP_Name` (id INT) BEGIN SELECT * FROM Table_Name WHERE Id = id; END// The two lines that are simply the database name followed by the delimiter are errors and are reported as such when running the script. As long as they are ignored, it looks like everything gets created just fine. But why would it add those lines? I am creating the database in the WAMP environment which uses MySQL 5.1.36

  • Using property file in hibernate mapping

    - by Zoltan Hamori
    Hi, I have a two nodes environment using the same database. In the database there is a resource table like RESOURCE_ID, CODE, NODE The content of the NODE column can be 1 or 2 depending on which node can use it. As I need to deploy the same ear to the two nodes, I would like to map this table like this: <hibernate-mapping> <class name="ResourceVO" table="RESOURCE" dynamic-update="true" optimistic-lock="dirty" where="NODE=${node.value}" > I would like to store the node.value property on the file system, so the instances could identify which resource to use. Is it possible in hibernate?

  • ASP.NET error on Bitmap.Save "Exception (0x80004005): A generic error occurred in GDI+."

    - by Batu
    Hi, I have a function which first reads an image from disk, resizes it and then saves to another directory. when i use the Bitmap.Save(directory + theimagename) it returns the error as i stated in the question title. i checked the directory is right, and the given image name doesn't exist in that dir. what is weird, is that the same code works great on the local machine. but when i upload it to my shared server. it just doesn't work. the code is below. bmpOut = new Bitmap(Size, Size); Graphics g = Graphics.FromImage(bmpOut); g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; g.FillRectangle(Brushes.White, 0, 0, Size, Size); int topBottomPadding = 0; int leftRightPadding = 0; if (Size > lnNewWidth + 1) leftRightPadding = Convert.ToInt32((Size - lnNewWidth) / 2); else if (Size > lnNewHeight + 1) topBottomPadding = Convert.ToInt32((Size - lnNewHeight) / 2); g.DrawImage(loBMP, leftRightPadding, topBottomPadding, lnNewWidth, lnNewHeight); Bitmap bmp = new Bitmap(bmpOut); if (bmp != null) bmp.Save(ResizedOutput); bmp.Dispose(); bmpOut.Dispose(); g.Dispose(); loBMP.Dispose(); stack trace: [ExternalException (0x80004005): A generic error occurred in GDI+.] System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams) +377630 System.Drawing.Image.Save(String filename, ImageFormat format) +69 System.Drawing.Image.Save(String filename) +25 Utilities.ResizeImage(String fileName, String mode) in c:\inetpub\vhosts\batuhanakcay.com\httpdocs\App_Code\Utilities.cs:181 Link.ToProductImage(String fileName) in c:\inetpub\vhosts\batuhanakcay.com\httpdocs\App_Code\Link.cs:79 Product.PopulateControls(ProductDetails pd) in c:\inetpub\vhosts\batuhanakcay.com\httpdocs\Product.aspx.cs:37 Product.Page_Load(Object sender, EventArgs e) in c:\inetpub\vhosts\batuhanakcay.com\httpdocs\Product.aspx.cs:20

  • Removing $_SESSION['layout']['action'] globally from all users!

    - by sologhost
    Ok, I am storing a session variable like so to load up users layouts faster if it's set instead of calling the database. But since the layout can be changed via the Administrator, I'd like to be able to globally remove all sessions where $_SESSION['layout']['action'] is set for all users. $_SESSION['layout']['action'] = array(a ton of indexes and mulit-dimensional arrays); Now, I know it's being stored into my database sessions table, there's a column for session_id, last_update, and data. So, question I have is how to remove that session array key ['action'] from all users. Using $_SESSION = array(); session_destroy(); Does not work. Basically, session_start() is being loaded on every page load, so I just want to remove all ['action'] keys from ['layout']. Is this possible to do? Thanks

  • Is it normal for C++ static initialization to appear twice in the same backtrace?

    - by Joseph Garvin
    I'm trying to debug a C++ program compiled with GCC that freezes at startup. GCC mutex protects function's static local variables, and it appears that waiting to acquire such a lock is why it freezes. How this happens is rather confusing. First module A's static initialization occurs (there are __static_init functions GCC invokes that are visible in the backtrace), which calls a function Foo(), that has a static local variable. The static local variable is an object who's constructor calls through several layers of functions, then suddenly the backtrace has a few ??'s, and then it's is in the static initialization of a second module B (the __static functions occur all over again), which then calls Foo(), but since Foo() never returned the first time the mutex on the local static variable is still set, and it locks. How can one static init trigger another? My first theory was shared libraries -- that module A would be calling some function in module B that would cause module B to load, thus triggering B's static init, but that doesn't appear to be the case. Module A doesn't use module B at all. So I have a second (and horrifying) guess. Say that: Module A uses some templated function or a function in a templated class, e.g. foo<int>::bar() Module B also uses foo<int>::bar() Module A doesn't depend on module B at all At link time, the linker has two instances of foo<int>::bar(), but this is OK because template functions are marked as weak symbols... At runtime, module A calls foo<int>::bar, and the static init of module B is triggered, even though module B doesn't depend on module A! Why? Because the linker decided to go with module B's instance of foo::bar instead of module A's instance at link time. Is this particular scenario valid? Or should one module's static init never trigger static init in another module?

  • jQuery JSON .each problem

    - by Aran
    I have a JSON object that looks like this. [ { "id" : "23", "event_id" : "0", "sport_title" : null, "event_title" : null, "title" : "Under 1 day!", "content" : "It\\'s all hotting up and battle commences in under one day!", "link" : "" }, { "id" : "20", "event_id" : "0", "sport_title" : null, "event_title" : null, "title" : "Getting Exciting", "content" : "Less than two days till it all kicks off, with cricket....", "link" : "" }] and I am trying to get the details out of this JSON Object and prepend them to a <ul> the code that I am currently trying looks like this and is having problems var writeup_list = writeuplist; $.getJSON('../json/getWriteups.json', function(data) { $.each(data.items, function(i, item) { writeup_list.html(function() { var output; output = '<li><a href="/writeups/index.php#writeup_' + item.id + '">'; if(item.sport_title != null) { output += item.sport_title + ' - '; } output += item.title + '</a></li>'; return output; }); }); }); writeuplist is just the ul object. I am also worried about overriding information that is already in the list or just adding again. Don't want to keep adding the same data. What is a good way to avoid this? I seem to be having a problem in getting the data out of the JSON file I believe it has something to do with the way am trying to access it in the .each function. Can anyone spot where am going wrong?

  • How to prevent session hijacking with SID (CGI perl)

    - by Gnippots
    I have a web app used by a small number of people (internal only) and am using a randomised sessionID that is stored under the user record and placed in various links. I have had a problem where users are sending links to each other which is allowing them to hijack the sender's session. What are some ways of preventing this from happening while still letting users send links to one another? Edit: The session ID in the link (which also contains $username) is just compared to what is stored in the User table. &incorrectLogin just prints an error followed by die; if ($sid) { $sth = $dbh->prepare("SELECT * FROM tbl_User WHERE UserID = '$username'"); $sth->execute(); $ref = $sth->fetchrow_hashref(); $session_chk = $ref->{'usr_sessionID'}; unless ($sid eq $session_chk) {&incorrectLogin;} } The problem is that if someone uses a link that is created by someone else, the page will load as them. I am not using cookies, and I recall being told in the past that CGI perl cookie handling is quite poor.

  • Open a new browser window from embeded Internet Explorer

    - by Buddy
    I am working on a Windows desktop app (C++) that has an embedded Internet Explorer page. I'm working on the html page that is displayed in the There is not a back button control, so one of the requests is that links clicked on in the page should open the link in a browser window. It can open the link in the users default browser or in IE. Is this possible? I realize that this is not possible because javascript is in a sandbox and cannot touch outside applications. I'm thinking there might be a way because it is using the IE. I have tried the two methods that have worked for me in the past. Using jquery, I've tried these two approaches, but neither work in the app. They both work fine in normal browsers. Using target="_blank" $( "a" ).attr( "target", "_blank" ); The other is using window.open: $( "a" ).click( function() { window.open( $( this ).attr( "href" ) ); } ); I'm afraid that writing windows desktop applications is outside my area of expertise, so I cannot give more information regarding that side of the issue.

  • Query DNSBL or other block lists using PHP

    - by 55skidoo
    Is there any way to use PHP code to query a DNSBL (block list) provider and find out if the IP address submitted is a bad actor? I would like to take an existing IP address out of a registration database, then check whether it's a known block-listed IP address by performing a lookup on it, then if it's a blacklisted, do an action on it (such as, delete entry from registration database). Most of the instructions I have seen assume you are trying to query the blocklist via a mail server, which I can't do. I tried querying via web browser by typing in queries such as "58.64.xx.xxx.dnsbl.sorbs.net" but that didn't work.
