[ "Javascript if this OR this statement - second condition ignored", "I have to show different divs based on what search terms are entered into my site. The URL will contain the search term entered, so I thought I could check for the string in the URL and show the div if there is a match. \n\nFor the Doufeu/doufeu part, the div will only show based on the first term. The code is below - it will only show if Doufeu is in the string, but not doufeu. Why?\n\nBased on what I read here and here, I have tried the code below, and also using && instead of || because the second link explains the second condition is only read if the first one is false. I found this and also tried separating with a comma. None work for me though. Here is where I am now:\n\n <script type=\"text/javascript\">\n $(document).ready(function(){\n\n if ((window.location.href.indexOf(\"searchTerm=Doufeu\" || \"searchTerm=doufeu\") > -1)){\n $(\"#learn-doufeu\").show();\n }\n\n else {\n $(\"#ci-guide\").show();\n }\n });\n </script>\n\n\nI know I could make a new if else condition and separate Doufeu from doufeu that way but surely there is a way to do it with OR." ]

However, as of now, I only have the navigation controller. One of the things I am having trouble with is getting the button at the end to pop up an alert view when pressed, so to say something like \"Story finished! Go back to start!\" and then of course the \"Okay\" button part on the alert view.\n\nI know how to make an alert view, but only popping up because of a condition. We had a project called Tic-Tac-Toe, and when one wins, an alert view pops up. What I want to do with my CYOA app is make it so when you press the \"Go Back To Start\" button an alert view will pop up, as well as take you back to the initial view controller. The navigation controller will also be available in the app, so I do not want to take that out, however, having a \"Go Back To Start\" button at the end of each story line or path, will allow the user to not have to go back through the previous story line that they just came from, and rather save them a bit of taps.\n\nCode for my project\n\nThere (pictured above) is the code for one of the ends.

Luckily the document always has the same name, but sadly the document isn't always in the same location relative to the media files I'm trying to link it to. The most sensible workaround I've found is looking for the closest file with a similar name in the directory structure.

Sadly, this is pretty slow and I would like to be able to do this for a large number media files so I'm looking for a more elegant solution.

These objects connect with each other via a connection object of type 'b'. An 'a' object can hold many 'b' objects, and each 'b' object holds only a single 'a' object. So basically, I have a network of 'a' objects with 0 or more connections to other 'a' objects via 'b' objects.\n\nA given 'a' object's list of 'b' objects is variable; 'b' objects can be added or removed from an 'a' object's list. However, when a 'b' object is removed from an 'a' object's list, this sometimes causes Entity Framework to error out when trying to save the network of 'a' objects later on down the line. An 'a' object's 'b' object removal code looks like this:\n\npublic void RemoveConnection(b connectionObject)\n {\n myBObjects.remove(connectionObject);\n }\n\n\nThis method works fine when the code is running, and the 'a' objects have a correct list of 'b' objects at save time. The following is the save code:\n\nusing (var db = new PersistenceContext())\n {\n db.NetworkOfAs.Add(network);\n db.SaveChanges();\n }\n\n\nIf a 'b' object has never been removed from an 'a' object's list of 'b' objects, the above works just fine. If a 'b' object is removed from an 'a' object's list of 'b' objects but the list of 'b' objects remains greater or equal to length 1, the above also works fine. However, if a 'b' object was added and then removed from an 'a' object's list of 'b' objects such that the 'a' object's list of 'b' objects returns to length 0, I get the following error:\n\nThe INSERT statement conflicted with the FOREIGN KEY constraint \n\"FK_dbo.BObjects_dbo.AObjects_Id\". The conflict occurred in database \n\"NetworkDatabase.PersistenceContext\\\", table \\\"dbo.AObjects\\\", column 'Id'\n\n\nI've been digging into debugging this for several days now, and it seems pretty apparent that this is being caused by Entity Framework trying to save the 'b' objects which have been removed from a given 'a' object's list of 'b' objects. However, I have no idea how to prevent this, and can't seem to find anything describing this particular issue.\n\nAny help is much appreciated, and if this explanation is missing any necessary details please let me know." ]

[ "webapp security by id signing", "Suppose I write a web application that stores a lot of information in its database that should only be accessible to users with privileges. A post, for example, may only be readable by its author. For the sake of the example, suppose that each word in the post is assigned an id and must also be checked to see if the user actually has permission to use that word. When transmitting ajax requests to the server, the ids must all be sent to the server for the request (details of why aren't important). For security, I want to verify that the user is authorized to use each word to foil an attacker that is fabricating his own ajax request. I could query the SQL database for each word to check authorization which will probably involve one or more joins. This results in 100s of queries. I would like to avoid querying so much. (In my specific implementation, I'm not using posts and words, but I will need to handle ~100 database ids in some requests.)\n\nI came up with a possible solution and I would like some feedback. Instead of transmitting integers as ids to the web application, it encodes the id in a signed-id-placeholder. The signature works by assigning every session a secret key that is stored in the session table and not send to the client. To encode an id, the id, id type ('user_id', etc.), and the secret key are appended together and piped through a hash algorithm. A fixed length portion of this resulting hash is appended to the unencoded id and then sent to the client. To reduce its length, it's also encoded with 0-9,A-Z,a-z or base-62. The result is that the actual id is in clear-text (though slightly masked by the different base) and a signature is appended to it. This way, changing the id will invalidate the signature and the server will not honor the request. In my current implementation, I'm using a signature length of 56 bits for about 7.2x10^16 possible signatures.\n\nWhat are you reactions to this plan? Overkill? Flawed? Is there an accepted, better solution?\n\nHere is a code snipet in php of the signing function (excuse the use of magic numbers, this is a testing implementation):\n\npublic function signDbId( $id, $kind )\n{\n $id_seg = base62( $id );\n $hash = md5( $id_seg . $kind . $this->session_key );\n $signed = '';\n for ( $i = 0; $i < 2; ++$i )\n {\n $signed .= base62( intval( substr( $hash, $i*8, 7 ), 16 ), 5 );\n // pad to 5 chars\n }\n return $signed . $id_seg;\n}" ]
