  • PHP & form validation

    - by user887515
    I have a form that I'm submitting via ajax, and I want to return a message of the list of fields that were empty. I've got that all done and dusted, but it just seems really long winded on the PHP side of things. How can I do the below in a less convoluted way? <?php if(empty($_POST["emailaddress"])){ $error = 'true'; $validation_msg = 'Country missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if(empty($_POST["password"])){ $error = 'true'; $validation_msg = 'Country missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if(empty($_POST["firstname"])){ $error = 'true'; $validation_msg = 'First name missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if(empty($_POST["lastname"])){ $error = 'true'; $validation_msg = 'Last name missing.'; if(empty($error_msg)){ $error_msg .= $validation_msg; } else{ $error_msg .= '\n' . $validation_msg; } } if($error){ header('HTTP/1.1 500 Internal Server Error'); header('Content-Type: application/json'); die($error_msg); } ?>

  • How can I handle an empty namespace with XDocument.XPathEvaluate?

    - by Kevin
    I'm trying to use XDocument and XPathEvaluate to get values from the woot.com feed. I'm handling other namespaces fine, but this example is giving me problems. <rss xmlns:a10="http://www.w3.org/2005/Atom" version="2.0"> <channel> <category text="Comedy" xmlns="http://www.itunes.com/dtds/podcast-1.0.dtd"> </category> <!-- this is a problem node, notice 'xmlns=' --!> So I try this: XmlNamespaceManager man = new XmlNamespaceManager(nt); man.AddNamespace("ns", "http://www.w3.org/2000/xmlns/"); // i've also tried man.AddNamespace("ns", string.Empty); xDocument.Namespace = man; var val = xDocument.XPathEvaluate("/rss/channel/ns:category/@text", xdwn.Namespace); val is always null. I'm using ns: from the suggestion from VS 2010 XPath Navigator plugin. Any thoughts on how to handle this?

  • Display empty textbox using Html.TextBoxFor on a not-null property in an EF entity.

    - by hungster
    I am using Entity Framework (v4) entities. I have an entity called Car with a Year property of type integer. The Year property does not allow NULL. I have the following in my Create view: <%= Html.TextBoxFor(model => model.Year) %> I am required to return a new Car object (due to other requirements) in my HttpGet Create action in the CarController. Currently, a zero is displayed in the Year textbox because the Year property does not allow NULL. I would like to display an empty textbox in the Create view. How do I do this?

  • How do I create an empty array/matrix in NumPy?

    - by Ben
    I'm sure I must be being very dumb, but I can't figure out how to use an array or matrix in the way that I would normally use a list. I.e., I want to create an empty array (or matrix) and then add one column (or row) to it at a time. At the moment the only way I can find to do this is like: mat = None for col in columns: if mat is None: mat = col else: mat = hstack((mat, col)) Whereas if it were a list, I'd do something like this: list = [] for item in data: list.append(item) Is there a way to use that kind of notation for NumPy arrays or matrices? (Or a better way -- I'm still pretty new to python!)

  • WPF: "Items collection must be empty before using ItemsSource."

    - by Zack Peterson
    I'm trying to get images to display in a WPF ListView styled like a WrapPanel as described in this old ATC Avalon Team article: How to Create a Custom View. When I try to populate the ListView with a LINQ-to-Entities queried collection of ADO.NET Entity Framework objects I get the following exception: Exception Items collection must be empty before using ItemsSource. My code… Visual Basic Private Sub Window1_Loaded(...) Handles MyBase.Loaded ListViewImages.ItemsSource = From g In db.Graphic _ Order By g.DateAdded Ascending _ Select g End Sub XAML <ListView Name="ListViewImages" SelectionMode="Single" ItemsSource="{Binding}"> <local:ImageView /> </ListView> I put a breakpoint on that line. ListViewImages.ItemsSource is Nothing just before the LINQ assignment.

  • Why is the form action attribute empty on production server?

    - by Ozzy
    After deploying a ASP.NET WebForms application to a production server some of the ajax calls has stopped working for me. After some debugging I found out that the following statement (in the internal client-method WebForm_DoCallback) was causing the problem: xmlRequest.open("POST", action, true); The problem seemed to be that the action-variable was empty so after checking the rendered html I found out that the form-tag rendered on the production server looks like: <form method="post" action="" id="Form1"> However, on my developer machine I get the following: <form method="post" action="default.aspx" id="Form1"> So, why would the action-attibute render on my dev.machine but not on the production server? This seems to be the case only for one specific web form, when I look on other pages the action-attribute renders correctly. Any suggestions or ideas would be helpful!

  • How can I make a DateTimePicker display an empty string?

    - by brass-kazoo
    I would like to be able to display a DateTimePicker that has a default value of nothing, i.e. no date. For example, I have a start date dtTaskStart and an end date dtTaskEnd for a task, but the end date is not known, and not populated initially. I have specified a custom format of yyyy-MM-dd for both controls. Setting the value to null, or an empty string at runtime causes an error, so how can I accomplish this? I have considered using a checkbox to control the enabling of this field, but there is still the issue of displaying an initial value.. Edit: Arguably a duplicate of the question DateTimePicker Null Value (.NET), but the solution I found for my problem is not a solution for that question, so I think it should remain here for others to find..

  • UIView subclass draws background despite completely empty drawRect: - why?

    - by Pascal
    So, I have a custom UIView subclass which enables drawing of rounded edges. The thing draws perfectly, however the background always fills the whole bounds, despite clipping to a path first. The border also draws above the rectangular background, despite the fact that I draw the border in drawRect: before the background. So I removed the whole content of drawRect:, which is now virtually empty - nevertheless the background gets drawn! Anybody an explanation for this? I set the backgroundColor in Interface Builder. Thanks!

  • How do I return an empty result set from a procedure using T-SQL?

    - by Kivin
    I'm interested in returning an empty result set from SQL Server stored procedures in certain events. The intended behaviour is that a L2SQL DataContext.SPName().SingleOrDefault() will result in CLR null value. I'm presently using the following solution, but I'm unsure whether it would be considered bad practice, a performance hazard (I could not find one by reading the execution plan), or if there is simply a better way: SELECT * FROM [dbo].[TableName] WHERE 0 = 1; The execution plan is a constant scan with a trivial cost associated with it. The reason I am asking this instead of simply not running any SELECTs is because I'm concerned previous SELECT @scalar or SELECT INTO statements could cause unintended result sets to be served back to L2SQL. Am I worrying over nothing?

  • Java: I am trying to server a zip file through a link, but the file comes out as being empty

    - by Ankur
    I am trying to server a zip file through a link, but the file comes out as being empty. My app takes a number of files and zips them up, then presents the user with a link to the file so he/she can download it. On the server I can see that the zip file is being created correctly, but when I download it from the server through the normal HTML link provided no data is downloaded i.e. a zip file is created locally but it has file size 0kb. The file names are of the form XPCS.2010-03-09.15.13.42.165.zip - will the dots cause problems?

  • Files written with FileWriter are either 32 KB, 24 KB, 16 KB, ... big or empty

    - by Bernhard V
    Hi, I read a file into a string, change the first line and then write this string into a new file. I do this through the following code (a little bit shortened): while(jspIterator.hasNext()){ String line = (String) jspIterator.next(); if (i == 0) { if (line.startsWith("bla bla") && line.endsWith("yada")) { line = line.replaceFirst("this", "that"); } } jspAsString += line; i++; } FileWriter newJspWriter = new FileWriter(newJspFile); newJspWriter.write(jspAsString); Now the files written this way are either 32, 24, 16, 8 KByte big or completely empty. When debugging I see that the String is assembled correctly. When I print the variable jspAsString to the console it also appears correct. Do you know why FileWriter behaves this way?

  • Keystore in PKCS12 format seems empty to keytool, but is read by Firefox?!

    - by hjh
    I have a problem with a keystore in pkcs12 format, which contains a private key I need to use to authenticate myself (using mutual authentication) to a remote SSL server. The keystore file can be read perfectly fine by Firefox, and when used, I can access the remote server without problems. However, my Java program does not work with the keystore file. And if I use keytool to list keys inside the file, it seems empty -- while it is clearly not! How can I get Java/keytool to see the private key inside the keystore?

  • file_get_contents returns an empty string that is 354 bytes long.

    I'm trying to read the contents of a file and simply getting an empty string. The file exists on the server. I've tried some test with the following code and get the true to display: $filename = "includes/blah.php"; $filecontents = file_get_contents($filename, FILE_USE_INCLUDE_PATH); if ($filecontents === false) { echo(":FALSE:"); } else { echo(":TRUE:"); } var_dump($filecontents); The dump displays "string(354)" which is the correct size of the file. What am I doing wrong?

  • Possible to have empty values with Html For Helpers such as Html.TextBoxFor()?

    - by chobo2
    Hi Is it possible to have to make a html for helper in asp.net mvc 2.0 have a default value of "empty string" Like if I do this Html.TextBoxFor( u => u.ProductName) would render to <input id ="ProductName" name="ProdcutName" type="text" value="Jim" /> Now I don't want the textbox to display jim. I want it to display nothing. <input id ="ProductName" name="ProdcutName" type="text" value="" /> I tried to do this Html.TextBoxFor( u => u.ProductName, new { @value = " "}) but that seems to do nothing. So how can I do this. I hope you can do something like this otherwise I think these new helpers have a great flaw since now I need to use like javascript to remove them since I hardly ever want a default value in the textbox especially when I have a label right beside the textbox saying what it is.

  • How to draw or put a text on empty an UITableViewController ?

    - by elementsense
    Hi I have a app that starts with a empty UITableViewController, which is pretty .. well, emtpy. Now I was wondering if I could hint the user by painting something else on the view, like pointing an arrow to the plus button and say something like "press here to add something new" I'll guess I have to do this in the viewDidLoad method, where I also init my NSFetchedResultsController, so I actually know if there are any objects in my list. I never put controls on the screen by code so I am not sure where to start and where to put em on. will that be the [self view] ? Thanks
