  • Dynamic jQuery Validate error messages with AddMethod based on the element

    - by mcpDESIGNS
    Let's say I have a custom AddMethod to jQuery Validate like: $.validator.addMethod('min-length', function (val, element) { // do stuff // the error message here needs to be dynamic }, 'The field cannot be less than than ' + element.attr('data-min') + // it is within the closure, but it can't grab it ' length.'); I can't figure out a way to get the element variable in question, and get any values from it. What am I missing here?

  • Haskell: Gluing a char and a list together?

    - by Vincent
    So I have this code here: toWords :: String - [a] toWords "" = [] toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest The "toWords" function should simply remove all spaces and return a list with all the words. But I keep getting this error: test.hs:5:18: Couldn't match expected type a' against inferred typeChar' `a' is a rigid type variable bound by the type signature for `toWords' at test.hs:1:22 In the first argument of `(:)', namely `nr1' In the expression: nr1 : toWords rest In the definition of `toWords': toWords (nr1 : rest) | nr1 == ' ' = toWords rest | otherwise = nr1 : toWords rest Failed, modules loaded: none.

  • iPhone memory management (with specific examples/questions)

    - by donkim
    Hey all. I know this question's been asked but I still don't have a clear picture of memory management in Objective-C. I feel like I have a pretty good grasp of it, but I'd still like some correct answers for the following code. I have a series of examples that I'd love for someone(s) to clarify. Setting a value for an instance variable. Say I have an NSMutableArray variable. In my class, when I initialize it, do I need to call a retain on it? Do I do fooArray = [[[NSMutableArray alloc] init] retain]; or fooArray = [[NSMutableArray alloc] init]; Does doing [[NSMutableArray alloc] init] already set the retain count to 1, so I wouldn't need to call retain on it? On the other hand, if I called a method that I know returns an autoreleased object, I would for sure have to call retain on it, right? Like so: fooString = [[NSString stringWithFormat:@"%d items", someInt] retain]; Properties. I ask about the retain because I'm a bit confused about how @property's automatic setter works. If I had set fooArray to be a @property with retain set, Objective-C will automatically create the following setter, right? - (void)setFooArray:(NSMutableArray *)anArray { [fooArray release]; fooArray = [anArray retain]; } So, if I had code like this: self.fooArray = [[NSMutableArray alloc] init]; (which I believe is valid code), Objective-C creates a setter method that calls retain on the value assigned to fooArray. In this case, will the retain count actually be 2? Correct way of setting a value of a property. I know there are questions on this and (possibly) debates, but which is the right way to set a @property? This? self.fooArray = [[NSMutableArray alloc] init]; Or this? NSMutableArray *anArray = [[NSMutableArray alloc] init]; self.fooArray = anArray; [anArray release]; I'd love to get some clarification on these examples. Thanks!

  • Hacking "Contact Form 7" code to Add A "Referred By" field

    - by Scott B
    I've got about 6 subdomains that have a "contact us" link and I'm sending all these links to a single form that uses "Contact Form 7". I add ?from=site-name to each of the links so that I can set a $referredFrom variable in the contact form. The only two things I'm missing are (1) the ability to insert this referredFrom variable into the email that I get whenever someone submits the form and (2) The ability to redirect the user back to the site they came from (stored in $referredFrom) Any ideas? Here's a bit of code from includes/classes.php that I thought might be part of the email insert but its not doing much... function mail() { global $referrer; $refferedfrom = $referrer; //HERE IS MY CUSTOM CODE $fes = $this->form_scan_shortcode(); foreach ( $fes as $fe ) { $name = $fe['name']; $pipes = $fe['pipes']; if ( empty( $name ) ) continue; $value = $_POST[$name]; if ( WPCF7_USE_PIPE && is_a( $pipes, 'WPCF7_Pipes' ) && ! $pipes->zero() ) { if ( is_array( $value) ) { $new_value = array(); foreach ( $value as $v ) { $new_value[] = $pipes->do_pipe( $v ); } $value = $new_value; } else { $value = $pipes->do_pipe( $value ); } } $this->posted_data[$name] = $value; $this->posted_data[$refferedfrom] = $referrer; //HERE IS MY CUSTOM CODE } I'm also thinking that I could insert the referredFrom code somewhere in this function as well... function compose_and_send_mail( $mail_template ) { $regex = '/\[\s*([a-zA-Z][0-9a-zA-Z:._-]*)\s*\]/'; $callback = array( &$this, 'mail_callback' ); $mail_subject = preg_replace_callback( $regex, $callback, $mail_template['subject'] ); $mail_sender = preg_replace_callback( $regex, $callback, $mail_template['sender'] ); $mail_body = preg_replace_callback( $regex, $callback, $mail_template['body'] ); $mail_recipient = preg_replace_callback( $regex, $callback, $mail_template['recipient'] ); $mail_headers = "From: $mail_sender\n"; if ( $mail_template['use_html'] ) $mail_headers .= "Content-Type: text/html\n"; $mail_additional_headers = preg_replace_callback( $regex, $callback, $mail_template['additional_headers'] ); $mail_headers .= trim( $mail_additional_headers ) . "\n"; if ( $this->uploaded_files ) { $for_this_mail = array(); foreach ( $this->uploaded_files as $name => $path ) { if ( false === strpos( $mail_template['attachments'], "[${name}]" ) ) continue; $for_this_mail[] = $path; } return @wp_mail( $mail_recipient, $mail_subject, $mail_body, $mail_headers, $for_this_mail ); } else { return @wp_mail( $mail_recipient, $mail_subject, $mail_body, $mail_headers ); } }

  • Javascript Alert Return value / Event

    - by Chris
    Hey, The question is pretty simple, but i'm not the big AJAX/JS coder, so I have no clue if it's possible. Is there any way that I can check whether or not an alert() was executed on a remote site? Like if I inputted an alert("Welcome to this site"); through a get variable, is there any way to check if it that alert() was actually executed in the browser? And not necessarily through AJAX/JS.

  • dao as a member of a servlet - normal?

    - by EugeneP
    I guess, DAO is thread safe, does not use any class members. So can it be used without any problem as a private field of a Servlet ? We need only one copy, and multiple threads can access it simultaneously, so why bother creating a local variable, right?

  • How many indexes will actually get used?

    - by Ender
    I'm writing a page that does very simple search queries, resulting in something like: SELECT * FROM my_table WHERE A in (a1, a2, a3) AND B in (b1, b2) AND C in (c1, c2, c3, c4) AND And so on for a variable number of columns, usually ~5. If I create a separate index for each column (one for A, one for B, one for C, not (A,B,C)), will all of them be used in the above query?

  • Tracing memory leaks

    - by iFloh
    My favorite candidate again. I am in the process of identifying memory leaks in my app (a puzzling challenge for a newbe like me). I am using the xCode leak analyzer, but what puzzles me is how to trace back a memory leak to its variable or value. Is there a pointer to the instances that have reserved a memory address where a leak is identifyed? How do I best go about it?

  • how to selectively filter items in a collection

    - by Samuel
    I use the following snippet to filter the list of selected users, where isSelected is a boolean variable. Is there a simpler way (helper function) to populate the selectedUsers collection instead of writing the following lines of code. List<User> selectedUsers = new ArrayList<User>(0); for (User user : this.getUsers()) { if (user.isSelected()) { selectedUsers.add(user.getId()); } }

  • What alternatives to __attribute__ exist on 64-bit kernels?

    - by Saifi Khan
    Hi: Is there any alternative to non-ISO gcc specific extension __attribute__ on 64-bit kernels ? Three types that i've noticed are: function attributes, type attributes and variable attributes. eg. i'd like to avoid using __attribute__((__packed__)) for structures passed over the network, even though some gcc based code do use it. Any suggestions or pointers on how to entirely avoid __attribute__ usage in C systems/kernel code ? thanks Saifi.

  • Selecting all elements

    - by Eelke
    This should be really simple but I'm a javascript/jQuery rookie, so here we go: With the following code I can select a certain element var user = $(".ui-selected .user-name").html(); But if there are multiple elements with the above classes, only the first value gets selected. What I would like to accomplish is a variable with all the elements seperated by a , like: user1,user2,user3 ... etc. Any help would be greatly appreciated, thanks in advance!
