• PHP form validation submit problem?

  - by TaG

  My code is suppose to save a year like 1999 to the mysql database but it wont. It will check to see if the user has entered only numbers and is at least 4 numbers long or if nothing has been entered correctly but it wont save the correct year? How can I fix this problem. Here is the PHP code. if(isset($_POST['year']) && intval($_POST['year']) && strlen($_POST['year']) == 4) { $year = mysqli_real_escape_string($mysqli, $purifier->purify(htmlentities(strip_tags($_POST['year'])))); } else if($_POST['year'] && strlen($_POST['year']) < 4) { echo '<p class="error">year is not correct!</p>'; } else if($_POST['year'] == NULL) { // do something }

• How can i return List of directories instead of url's?

  - by user1741587

  I have this function : private List<string> getLinks(HtmlAgilityPack.HtmlDocument document) { List<string> mainLinks = new List<string>(); var linkNodes = document.DocumentNode.SelectNodes("//a[@href]"); if (linkNodes != null) { foreach (HtmlNode link in linkNodes) { var href = link.Attributes["href"].Value; if (href.StartsWith("http://") == true || href.StartsWith("https://") == true || href.StartsWith("www") == true) // filter for http { mainLinks.Add(href); } } } return mainLinks; } Its getting one url and return list of url's. Instead i want that the function will get a directory for example c:\ And it will return me a List of all directories in c:\ Not subsirectories just the directories in c:\ in my case it should be a List with a 14 directories. Meaning in each index in the List a directory. How can i do it ? Tried with Directory and DirectoryInfo but i just got messed up.

• Can I catch bad pointer errors in C++?

  - by Simon

  Hi there, I was wondering if there is a possibility to catch errors like this in C++: object* p = new object; delete p; delete p; //this would cause an error, can I catch this? Can I check if the pointer is valid? Can I catch some exception? I know I could set the pointer p to NULL after the first object deletion. But just imagine you wouldn't do that. I am using VC++ with Visual Studio 2008/2010. Thank you

• R: How to separate character output in a loop?

  - by John

  I'm blanking on the best way to paste a list of strings together to go into an SQL statement... I'm having trouble with the separator bar | printing at the beginning when I don't want it to: foo = "blah" paste_all_together = NULL for (n in 1:4) { paste_together = paste(foo ,sep = "") paste_all_together = paste(paste_all_together, paste_together, sep = "|") } > paste_all_together [1] "|blah|blah|blah|blah" I just want it to print out "blah|blah|blah|blah". Do I need a nested loop, or is there a better itterator in R for doing this? Or perhaps a better way to input SQL statements?

• Simple Sinatra Ajax Not Working

  - by proteantech

  I was trying make an AJAX call from a static file on my computer to a simple sinatra service. The ajax call was returning with an error and no details. The server logged no errors either. Another strange symptom was that the Origin in the request header was null. I turns out that you can't make cross domain ajax calls without a little extra effort. You can set the Access-Control-Allow-Origin header on your sinatra response to expose your service to external domains using a snippet like this: get '/hi' do response['Access-Control-Allow-Origin'] = '*' content_type 'text/plain' "Hello World" end There's also another header you can set to allow other HTTP Methods besides gets, Access-Control-Request-Method. You can find more information by searching around for CORS: Cross Origin Resource Sharing and the previously mentioned headers. Oh, and in case you want to do this in Rails as well you can do something like this in your controller: after_filter :set_access_control_headers def set_access_control_headers headers['Access-Control-Allow-Origin'] = '*' headers['Access-Control-Request-Method'] = '*' end

• Was: Not unique table :: Now: #1054 - Unknown column - can't understand why!?

  - by Andy Barlow

  Hi! I'm trying to join some tables together in MySQL, but I seem to get an error saying: #1066 - Not unique table/alias: 'calendar_jobs' I really want it to select everything from the cal_events, the 2 user bits and just the destination col from the jobs table, but become "null" if there arn't any job. A right join seemed to fit the bill but doesn't work! Can anyone help!? UPDATE: Thanks for the help on the previous query, I'm now up to this: SELECT calendar_events.* , calendar_users.doctorOrNurse, calendar_users.passportName, calendar_jobs.destination FROM `calendar_events` , `calendar_users` RIGHT JOIN calendar_jobs ON calendar_events.jobID = calendar_jobs.jobID WHERE `start` >= 0 AND calendar_users.userID = calendar_events.userID; But am now getting an error saying: #1054 - Unknown column 'calendar_events.jobID' in 'on clause' What is it this time!? Thanks again!

• "And" condition in C#/LINQ Query

  - by user1213055

  partial void PrintDocLetter1_CanExecute(ref bool result) { if (this.PatientsMasterItem.DoctorsMasterItem != null) { var Doctor = PatientsMasterItem.DoctorsMasterItem; var PatientList = Doctor.PatientsMasterItem; var Letters = PatientsMasterItem.LettersSentItem; if ((PatientList.Count() > 1) && (Letters.Any(i => i.LetterType == "DoctorLetter1"))) { result = false; } else { result = true; } } } I think something is wrong with my second condition. I'm trying to find two things. 1) Doctors with more than 1 patient. 2) Among those patients whether a lettertype called "DoctorLetter1" has been sent or not. The above code is working good for that particular record but not working other patients with same doctors where patient1 has already been sent with DoctorLetter1.

• Alternatives to sign() in sqlite for custom order by

  - by Pentium10

  I have a string column which contains some numeric fields, but a lot are 0, empty string or null. The rest are numbers having different range, all positive. I tried to create a custom order by. The order would be done by two fields. First I would like to order the fields that have this number 0 and then sort by name. So something this would work: select * from table order by sign(referenceid) desc, name asc; But Sqlite lacks the sign() -1/0/1 function, and I am on Android and I can't create user defined functions. What other options I have to get this sort done.

• Ignoring "Content is not allowed in trailing section" SAXException

  - by Paul J. Lucas

  I'm using Java's DocumentBuilder.parse(InputStream) to parse an XML document. Occasionally, I get malformed XML documents in that there is extra junk after the final > that causes a SAXException: Content is not allowed in trailing section. (In the cases I've seen, the junk is simply one or more null bytes.) I don't care what's after the final >. Is there an easy way to parse an entire XML document in Java and have it ignore any trailing junk? Note that by "ignore" I don't simply mean to catch and ignore the exception: I mean to ignore the trailing junk, throw no exception, and to return the Document object since the XML up to an including the final > is valid.

• Grails: can remoteField update multiple fields?

  - by Michael Bavin

  Hi, Assume i have a book entity with an isbn field. When entered a isbn number, i want 2 fields to be updated: title and author. My controller looks like this: def ajaxGetBook = { def book = Book.findByIsbn(params.isbn) if(book==null) book = new Book() render book as JSON } So my call works, and i get a full JSON Book. Now i would like to update 2 texfields by the update attribute <g:remoteField action="ajaxGetBook" update="title" name="isbn" value="${bookInstance?.book?.isbn}" paramName="isbn"/> Now the title field gets updated with the full book object, so that doesn't work. Is it possible to update field title with only the JSON book.title? Is it possible to update more fields at once? I could render book.title as JSON but that works for only one field. Thank you

• Rails passenger production cache definition

  - by mark

  Hi I'm having a bit of a problem with storing data in rails cache under production. What I currently have is this, though I have been trying to work this out for hours already: #production.rb config.cache_store = :mem_cache_store if defined?(PhusionPassenger) PhusionPassenger.on_event(:starting_worker_process) do |forked| if forked Rails.cache.instance_variable_get(:@data).reset end end end I am using a cron job to (try to) save remote data to the cache for display. It is logged as being written to the cache but reportedly null. If anyone could point me toward a decent current tutorial on the subject or offer guidance I'd be extremely grateful. This is really, really frustrating me. :(

• Sorting related objects in the Django Admin form interface

  - by Carver

  I am looking to sort the related objects that show up when editing an object using the admin form. So for example, I would like to take the following object: class Person(models.Model): first_name = models.CharField( ... ) last_name = models.CharField( ... ) hero = models.ForeignKey( 'self', null=True, blank=True ) and edit the first name, last name and hero using the admin interface. I want to sort the objects as they show up in the drop down by last name, first name (ascending). How do I do that? Context I'm using Django v1.1. I started by looking for help in the django admin docs, but didn't find the solution As you can see in the example, the foreign key is pointing to itself, but I expect it would be the same as pointing to a different model object. Bonus points for being able to filter the related objects, too (eg~ only allow selecting a hero with the same first name)
