  • I want jQuery validator to add a class to the form element's parent

    - by Eystein
    How do I use jQuery validator to add/remove a classname (e.g. validate) on the form element's parent <li> so I can style everything related to that element by only setting the one classname? The markup is <li class="validate"> <label for="product">Product of interest <abbr title="Required field">*</abbr></label> <input id="product" type="text" name="product" value="" placeholder="e.g. school bench" class="required" minlength="2"> <!-- Hidden by CSS unless parent has 'validate' class --> <label for="product" class="description">Please name a product.</label> </li> and the default jQuery is $("#commentForm").validate();

  • DB fields not showing up in association custom queries?

    - by Kevin
    I have a notification list that the user can select different show options for different kinds of notifications along with how many results are returned. I'm keeping them in the user model because I want the custom sort to stay with the user between sessions. Here is the association in my user model: has_many :notifications, :class_name => "Notification", :foreign_key => "user_id", :conditions => ["won = ? and lost = ? and paid = ?", self.prefs_won, self.prefs_lost, self.prefs_paid], :limit => self.prefs_results.to_s But when I use the above code, Rails throws me an "unknown method" error for self.prefs_won. It is definitely a field in my database and set as a boolean value, but Rails can't find it... what's the problem?

  • Seek a jQuery-based inplace HTML editor

    - by justSteve
    I just stepped over to http://plugins.jquery.com/search/node/editor - lots and lots of choices - and if to judge by the dates, many new offerings. I'm hoping someone can help me narrow down the field according to these priorities... Stability & Well-formed XHTML (might argue against some of the most recent unless they are revisions with a clear track-record) Inplace editing Good AJAX integration For internal / admin / CMS usage so it can be as bloated as it needs to be long as it's easy to implement the basics: bold ital indents lists No need for tables but dropdowns that show relevent CSS selectors would be nice. thnkx

  • Best way to manage the persistence of a form state, to and from a database

    - by Laurent.B
    In a JSP/Servlet webapp, I have to implement a functionality that allows a user to save or restore a form state, that latter containing for instance some search criteria. In other words, the user must be able to save or restore field values of a form, at any time. On the same page that contains that form, there's also another little form that allows him to name his form state before saving it. Then, later he'll be able to recall that state, via a combobox, and refill dynamically the form with the state he selected. I know how to implement that by hand but I would prefer not to reinvent the wheel then I'd like to know if there are some frameworks managing that kind of functionality ? A mix between JSP taglib, filter class, jQuery or other JavaScript frameworks... My research has not give anything yet. Thank you in advance.

  • ctype_alpha but allow spaces(php)

    - by helloo
    I was wondering if one can allow spaces in a textfield when checking it with ctype_alpha. Since ctype_alpha only allows alphabetical letters, I don't know how to let the user enter space in the field. I did try using ctype_space but that didn't work. I simply want the user to be able to type only alphabets and they have a choice to include spaces if they "wish." I hope I will not have to use regexp as I am very new to all of this and hope to learn it at a later date. Below is some of the code...Thank you. elseif (!ctype_alpha($fname)) { echo "Your name may only contain alphabetical letters"; }

  • How do I identify where the POST data sent to a PHP script came from?

    - by Mike Turley
    I have a ton of data collection forms on my website, and I wrote a PHP script to handle all the data. All the forms have that one script as their action, and POST as the method. The handler emails a copy of the data to me, and I'd like for the emails I get to contain the URL of the form where they originated. Is there any way in PHP to get the url of the form which was submitted to the script? Or do I have to add an extra hidden field in every form with its URL?

  • Database table schema design - varchar(n). Suitable choice of N

    - by morpheous
    Coming from a C background, I may be getting too anal about this and worrying unnecessarily about bits and bytes here. Still, I cant help thinking how the data is actually stored and that if I choose an N which is easily factorizable into a power of 2, the database will be more effecient in how it packs data etc. Using this "logic", I have a string field in a table which is a variable length up to 21 chars. I am tempted to use 32 instead of 21, for the reason given above - however now I am thinking that I am wasting disk space because there will be space allocated for 11 extra chars that are guaranteed to be never used. Since I envisage storing several tens of thousands of rows a day, it all adds up. Question: Mindful of all of the above, Should I declare varchar(21) or varchar(32) and why?

  • parallel.foreach with custom collection

    - by SchwartzE
    I am extending the System.Net.Mail.MailAddress class to include an ID field, so I created a new custom MailAddress class that inherited from the existing class and a new custom MailAddressCollection class. I then overrode the existing System.Net.Mail.MailMessage.To to use my new collection. I would like to process the recipients in parallel, but I can't get the syntax right. This is the syntax I am using. Parallel.ForEach(EmailMessage.To, (MailAddress address) => { emailService.InsertRecipient(emailId, address.DisplayName, address.Address, " "); }); I get the following errors: The best overloaded method match for 'System.Threading.Tasks.Parallel.ForEach(System.Collections.Generic.IEnumerable, System.Action)' has some invalid arguments Argument 1: cannot convert from 'EmailService.MailAddressCollection' to 'System.Collections.Generic.IEnumerable' What syntax do I need to use custom collections?

  • Jquery Match() IP Address?

    - by user1635970
    I'm using a jquery script to validate form fields. This works well, but I'd like to change the validation of one field to check for IP Addresses. The regex I want to use is : \b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b How do I amend the below to work with this ? (This is how the validation works for email address) jQuery("#Email").validate({ expression: "if (VAL.match(/^[^\\W][a-zA-Z0-9\\_\\-\\.]+([a-zA-Z0-9\\_\\-\\.]+)*\\@[a-zA-Z0-9_]+(\\.[a-zA-Z0-9_]+)*\\.[a-zA-Z]{2,4}$/)) return true; else return false;", message: "Should be a valid Email id" });

  • Is there an alternative of using a VBScript for enabling FileStream after SQL Server installation?

    - by user193655
    To use Filestream on a DB 3 steps must be done: 1) enable it a server/instance level 2) enable it (sp_configure) at DB level 3) create a varbinary(max) field that supports filestream (2) and (3) are done easily with T-SQL (1) is doable manually from SQL Server Configuration Manager, basically what I need is to check all the 3 checkboxes: but how is it possible to automize it? I found this artcile "Enabling filestream usin a VBScript", is there another way to do it than using VBScripts? May be something that is possible to do only with 2008R2? In case it VBScript is the only solution, which are the possible downsides?

  • Imposing email limits on web page

    - by Martin
    To avoid spammers, what's a good strategy for imposing limits on users when sending email from our site? A count limit per day on individual IPs? Sender emails? Domains? In general terms, but recommended figures will also be helpful. Our users can send emails through our web page. They can register and log in but are also allowed to do this without logging in, but with a captcha and with a field for the senders email. Certainly, there is a header, "The user has sent you the following message.", limiting the use for spammers, so perhaps it's not a big problem. Any comments on what I'm doing will be greatly appreciated.

  • C++ Singleton design pattern

    - by Artem Barger
    Recently I've bumped into a realization/implementation of the Singleton design pattern for C++. It has looked like this (I have adopted it from the real life example): // a lot of methods are omitted here class Singleton { public: static Singleton* getInstance( ); ~Singleton( ); private: Singleton( ); static Singleton* instance; }; From this declaration I can deduce that the instance field is initiated on the heap. That means there is a memory allocation. What is completely unclear for me is when exactly the memory is going to be deallocated? Or is there a bug and memory leak? It seems like there is a problem in the implementation. My main question is, how do I implement it in the right way?

  • Keyup attribute 'name' change not working

    - by dclowd9901
    Hey guys, I've got what I imagine is a simple question, but for some reason, I can't get it working right. Expected Behavior: I type characters into a field, and, through a function, those characters are translated into the value of the name HTML attribute. Actual Behavior: Reflected in Firebug, the value doesn't change or update. The Code: $('input').live('keyup', function() { var name_value = $(this).val().toLowerCase(); $(this).attr('name', name_value); }); Just a side note: I'm using .live() because the element can be cloned, and those clones need to also be able to take on the properties of this .keyup event. Any ideas?

The WorkOPRder_Table has WorkOrd_ID int and WrkOrd nvarchar(10) the Combo Box Data Source is WorkOrd_Table Display Member is WorkOrd Value Member is WorkOrder_ID This works great with the problem that I cannot add or select anything not in WorkOrder_table. Any Help would be greatly appreciated. Thanks

  • For securing forms, when do I issue the token?

    - by AQuestionADayKeepsTheDrAway
    So, I have a form, to make it a little more secure and potentially help prevent CSRF attacks I want to add a random token value in a hidden field that value is also stored server side in my session data. When should I issue a new token? Per form? Per page load where there is any form? Per session? I can render it invalid as soon as a form is successfully submitted but I'm wondering when to generate one. I ask as if I issue it per form or per page do I not risk the chance of a duplicate token value overwriting the existing (valid) token if a user opens a separate window but submitting the first form (with the now overwritten value)?

  • Django admin panel doesn't work after modify default user model.

    - by damienix
    I was trying to extend user profile. I founded a few solutions, but the most recommended was to create new user class containing foreign key to original django.contrib.auth.models.User class. I did it with this so i have in models.py: class UserProfile(models.Model): user = models.ForeignKey(User, unique=True) website_url = models.URLField(verify_exists=False) and in my admin.py from django.contrib import admin from someapp.models import * from django.contrib.auth.admin import UserAdmin # Define an inline admin descriptor for UserProfile model class UserProfileInline(admin.TabularInline): model = UserProfile fk_name = 'user' max_num = 1 # Define a new UserAdmin class class MyUserAdmin(UserAdmin): inlines = [UserProfileInline, ] # Re-register UserAdmin admin.site.unregister(User) admin.site.register(User, MyUserAdmin) And now when I'm trying to create/edit user in admin panel i have an error: "Unknown column 'content_userprofile.id' in 'field list'" where content is my appname. I was trying to add line AUTH_PROFILE_MODULE = 'content.UserProfile' to my settings.py but with no effect. How to tell panel admin to know how to correctly display fields in user form?

  • Accessing Variables in Javascript using .length

    - by CoV
    Hey all, I'm pretty new to Javascript, so forgive me if this is a simple question. I'm trying to access the length of a set of checkboxes in a form using Javascript. However, I need to be able to change the "name" field of the checkboxes to check several different sets of them. Right now, my sample code looks like: var set = "set" + x; totalLength = optionBoxes.set.length; The variable x is being incremented by a for loop that wraps the whole thing and the name of the checkbox sets that I'm trying to access are set0, set1, set2, etc. Thanks. Edit: small typo fixes

  • Easy way to compute how close an auto_increment is to its maximum value?

    - by David M
    So yesterday we had a table that has an auto_increment PK for a smallint that reached its maximum. We had to alter the table on an emergency basis, which is definitely not how we like to roll. Is there an easy way to report on how close each auto_increment field that we use is to its maximum? The best way I can think of is to do a SHOW CREATE TABLE statement, parse out the size of the auto-incremented column, then compare that to the AUTO_INCREMENT value for the table. On the other hand, given that the schema doesn't change very often, should I store information about the columns' maximum values and get the current AUTO_INCREMENT with SHOW TABLE STATUS?

  • Repairing broken XML file - removing extra less-than/greater-than signs

    - by peku
    I have a large XML file which in the middle contains the following: <ArticleName>Article 1 <START </ArticleName> Obviously libxml and other XML libraries can't read this because the less-than sign opens a new tag which is never closed. My question is, is there anything I can do to fix issues like this automatically (preferably in Ruby)? The solution should of course work for any field which has an error like this. Someone said SAX parsing could do the trick but I'm not sure how that would work.

  • Drupal: create a node with employee working hours

    - by JMarshall
    I have a bit complicated task. 1. I need to create a node with employee working hours (it's gonna be created for all users with role "employee"), which looks like this: Monday: From __ : __ To __ : __ Tuesday: From __ : __ To __ : __ Wednesday: From __ : __ To __ : __ etc. So, I'll have to create probably 14 CCK fields (monday_from, monday_to, tuesday_from...) or more to store the day of the week and workging hours (hours and minutes). 2. I need to add a view with exposed filters, where visitors can filter employees by day of the week and working hours. What kind of field should I use for working hours? How could views filtering described above be achieved? Any suggestions are greatly appreciated. Thank you!

  • Perl, get all hash values

    - by Mike
    Let's say in Perl I have a list of hash references, and each is required to contain a certain field, let's say foo. I want to create a list that contains all the mappings of foo. If there is a hash that does not contain foo the process should fail. @hash_list = ( {foo=>1}, {foo=>2} ); my @list = (); foreach my $item (@hash_list) { push(@list,$item->{foo}); } #list should be (1,2); Is there a more concise way of doing this in Perl?
