  • How to do an if statement on a function in PHP?

    - by Bruce
    I just realized that you can't just use an if statement on a function, for example this doesn't work: function sayHello() { echo "Hello World"; } if(sayHello()) echo "Function Worked"; else echo "Function Failed"; I also saw that a function can't be put as the value of a variable. So how can I do an if statement to check if a function has executed properly and display it to the browser?

  • I need an IDE for typo3 core development in php

    - by Flugan
    Php in itself is difficult for IDEs because of the dynamic nature of the language. My current development environment is mostly netbeans against a local svn copy of the codebase setup in a local development webserver. The code is full text indexed by vistas search engine for almost instant searches. I do a lot of development directly against the main development server using a combination of tools. Putty to interact with the server and deploy by updating an svn checkout on the development server. Tortoise SVN locally to have a fairly rich SVN experience. Netbeans obviously have SVN integration. Most of the changes on the remote server is commited using the putty session. WinSCP to interact with the development server with norton commander like interface as well as the good putty integration. Finally my text editor for remote editing is notepad++ out of habit and because of some nice features and good price. What I'm really missing is good php editing. Because of the way typo3 works almost all objects are instanciated through make instance abstraction that either returns the base class or the customized class if the framework has been extended. I'm not looking for a magic editing package and would like to find an editor which can use annotations to specify the type of commonly used variables.

  • Is it more efficient (Performance) to store the CFC in application variables OR instance the CFC on the page call?

    - by Mitchell Guimont
    Hello, I'm working on a ColdFusion dynamic website. For this website, there are a lot of CFCs and a lot of functions within each CFC. Would it be more efficient to store an instance of the CFC in an application variable, then to instance each CFC separately on each page load. For each page, at most 2 separate CFCs get called. I'm also interested in how performance will be effected when requests increase (Stress). Thanks!

  • Object-C: initWithContentsOfURL returning null

    - by AragornSG
    Hey! I'm working on an app that would display a remote html and use local images, so what I'm trying to do is download the HTML of the website and display it as a "local" page, that would have access to images in my bundle. For some reason I can't get initWithContentsOfURL to work. I checked all manuals and examples I could find and it seems that I'm doing it correctly, but the thing just won't work, returns null all the time. The same page loaded with NSURLRequest requestWithURL works fine. Appreciate your help! Here is the code: - (void)awakeFromNib { appURL = @"http://dragontest.fantasy-fan.org"; notConnectedHTML = @"Could not connect."; NSString *seedString = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@/seed.php", appURL]]]; NSString *HTMLdata = @""; if (seedString = @"(null)") { NSLog(@"Can't connect on awakeFromNib."); HTMLdata = notConnectedHTML; }else { HTMLdata = [NSString stringWithFormat:@"<body style='padding:0px;margin:0px;'>%@%@</body>", seedString, @"<br><img src='images/Default.png'>"]; } [homeView loadHTMLString:HTMLdata baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath]]]; }

  • Validating parameters according to a fixed reference

    - by James P.
    The following method is for setting the transfer type of an FTP connection. Basically, I'd like to validate the character input (see comments). Is this going overboard? Is there a more elegant approach? How do you approach parameter validation in general? Any comments are welcome. public void setTransferType(Character typeCharacter, Character optionalSecondCharacter) throws NumberFormatException, IOException { // http://www.nsftools.com/tips/RawFTP.htm#TYPE // Syntax: TYPE type-character [second-type-character] // // Sets the type of file to be transferred. type-character can be any // of: // // * A - ASCII text // * E - EBCDIC text // * I - image (binary data) // * L - local format // // For A and E, the second-type-character specifies how the text should // be interpreted. It can be: // // * N - Non-print (not destined for printing). This is the default if // second-type-character is omitted. // * T - Telnet format control (<CR>, <FF>, etc.) // * C - ASA Carriage Control // // For L, the second-type-character specifies the number of bits per // byte on the local system, and may not be omitted. final Set<Character> acceptedTypeCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'A','E','I','L'} )); final Set<Character> acceptedOptionalSecondCharacters = new HashSet<Character>(Arrays.asList( new Character[] {'N','T','C'} )); if( acceptedTypeCharacters.contains(typeCharacter) ) { if( new Character('A').equals( typeCharacter ) || new Character('E').equals( typeCharacter ) ){ if( acceptedOptionalSecondCharacters.contains(optionalSecondCharacter) ) { executeCommand("TYPE " + typeCharacter + " " + optionalSecondCharacter ); } } else { executeCommand("TYPE " + typeCharacter ); } } }

  • Methodology for a Rails app

    - by Aaron Vegh
    I'm undertaking a rather large conversion from a legacy database-driven Windows app to a Rails app. Because of the large number of forms and database tables involved, I want to make sure I've got the right methodology before getting too far. My chief concern is minimizing the amount of code I have to write. There are many models that interact together, and I want to make sure I'm using them correctly. Here's a simplified set of models: class Patient < ActiveRecord::Base has_many :PatientAddresses has_many :PatientFileStatuses end class PatientAddress < ActiveRecord::Base belongs_to :Patient end class PatientFileStatus < ActiveRecord::Base belongs_to :Patient end The controller determines if there's a Patient selected; everything else is based on that. In the view, I will be needing data from each of these models. But it seems like I have to write an instance variable in my controller for every attribute that I want to use. So I start writing code like this: @patient = Patient.find(session[:patient]) @patient_addresses = @patient.PatientAddresses @patient_file_statuses = @patient.PatientFileStatuses @enrollment_received_when = @patient_file_statuses[0].EnrollmentReceivedWhen @consent_received = @patient_file_statuses[0].ConsentReceived @consent_received_when = @patient_file_statuses[0].ConsentReceivedWhen The first three lines grab the Patient model and its relations. The next three lines are examples of my providing values to the view from one of those relations. The view has a combination of text fields and select fields to show the data above. For example: <%= select("patientfilestatus", "ConsentReceived", {"val1"="val1", "val2"="val2", "Written"="Written"}, :include_blank=true )% <%= calendar_date_select_tag "patient_file_statuses[EnrollmentReceivedWhen]", @enrollment_complete_when, :popup=:force % (BTW, the select tag isn't really working; I think I have to use collection_select?) My questions are: Do I have to manually declare the value of every instance variable in the controller, or can/should I do it within the view? What is the proper technique for displaying a select tag for data that's not the primary model? When I go to save changes to this form, will I have to manually pick out the attributes for each model and save them individually? Or is there a way to name the fields such that ActiveRecord does the right thing? Thanks in advance, Aaron.

  • Copy folder contents using VBScript

    - by LukeR
    I am trying to copy the contents of certain folders to another folder using VBScript. The goal is to enumerate a user's AD groups and then copy specific folder content based on those groups. I have code, which is currently not working. Dim Group,User,objFSO,objFolder,source,target,StrDomain StrDomain = "domain.local" FolderBase = "\\domain.local\netlogon\workgrps\icons" Set net = CreateObject("wscript.network") Struser = net.username target = "\\fs1\users\"&net.username&"\Desktop\AppIcons\" DispUserInWhichGroup() Function DispUserInWhichGroup() On Error Resume Next Set objFSO=CreateObject("Scripting.FileSystemObject") Set User = GetObject("WinNT://" & strDomain & "/" & strUser & ",user") For Each Group In User.Groups source = FolderBase & Group.name Set objFolder = GetFolder(source) For Each file in objFolder.Files objFSO.CopyFile source &"\"& file.name, target&"\"&file.name Next Next End Function This has been cobbled together from various sources, and I'm sure most of it is right, I just can't get it working completely. Any assistance would be great. Cheers.

  • How do I create a loop based off this array?

    - by dmanexe
    I'm trying to process this array, first testing for the presence of a check, then extrapolating the data from quantity to return a valid price. Here's the input for fixed amounts of items, with no variable quantity. <input type="checkbox" name="measure[<?=$item->id?>][checked]" value="<?=$item->id?>"> <input type="hidden" name="measure[<?=$item->id?>][quantity]" value="1" /> Here's the inputs for variable amounts of items. <input type="checkbox" name="measure[<?=$item->id?>][checked]" value="<?=$item->id?>"> <input class="item_mult" value="0" type="text" name="measure[<?=$item->id?>][quantity]" /> So, the resulting array is multidimensional. Here's an output: Array ( [1] => Array ( [quantity] => 1 ) [2] => Array ( [quantity] => 1 ) [3] => Array ( [quantity] => 1 ) ... [14] => Array ( [checked] => 14 [quantity] => 999 ) ) Here's the loop I'm using to take this array and process items checked off the form in the first place. I guess the question essentially boils down to how do I structure my conditional statement to incorporate the multi-dimensional array? foreach($field as $value): if ($value['checked'] == TRUE) { $query = $this->db->get_where('items', array('id' => $value['checked']))->row(); #Test to see if quantity input is present if ($value['quantity'] == TRUE) { $newprice = $value['quantity'] * $query->price; $totals[] = $newprice; } #Just return the base value if not else { $newprice = $query->price; $totals[] = $newprice; } } else { } ?> <p><?=$query->name?> - <?=money_format('%(#10n', $newprice)?></p> <? endforeach; ?>

  • Get SEO friendly URLS with Rails without mehtod_missing?

What we want are URLS like this: /students/BobSmith and NOT /students/show/342 IS there a cleaner solution than method_missing? Thank you!

  • Is there an easy way to get the ServerName in Symfony?

    - by greg0ire
    I have been searching for an easy way to get the ServerName of the machine where Symfony runs in Symfony (so that my app adapts when it is used on a host with a different ServerName), but I couldn't find one. I created a variable in app.yml and I fetch it, but I still wonder if there is no easier way to do this. How are you doing this? I'm using Symfony 1.2 and 1.4 on different projects.

  • javascript instanceof get type from string name

    Let's say I have this (assume the name variable is "receiver"): if (!(receiver instanceof com.HTMLReceiver)) { throw new com.IllegalArgumentException( name + " is not an instance of com.HTMLReceiver."); } I'd like to factor this code out into a common method so I could call it like this: Helper.checkInstance(receiver, "com.HTMLReceiver"); But I don't know of a way to convert the com.HTMLReceiver from a string to its actual type so I can use instanceof on it. Is there a way?
