simple server-side form informal

Hi, I built my first CF app for several months now, I've just moved to a "correct"host and now the outside world can see my practical work (or not as the case..) My classmates all go to "beta" my site tonight

My problem is that Javascript does my head so I left form validation at the last minute. My plan is to learn about the client side validation and server time and to implement a solution of the test of the bombs at the time - but only for the moment, I need to quickly add a few informal side server.

Is the road that I take (just for now to stop my fellow CF errors etc.)

1 submission form
2. review the form data with CFIF isDefined and Len (form.firstname) etc.
3 if my informal on the side code Server detects a problem, the user then gets their shape once again, prepopulated with their previous answers, but with any problem areas highlighted in red

-so far so good (this I can do)

My problem is I want to validate an email address as being in the correct format. I'm writing something to the effect of

form.emailAddress of IsDefined ("form.emailAddress") AND CFIF CONTAINS YEAR '@' SYMBOL >

but I don't know what the function will do that - I tried with ListFind but I'm sure that's not correct, and I can't make it work in all cases.

can anyone help please? Thank you very much.

You were so close.

Moreover, the best way to validate on the client must use cfform/cfinput. Then you can say required = "yes", post = "email" and things like that. Do not use the validate = 'time', it has some bugs.

  • server-side and client on the same form-side code

    I CFINPUT text on the form and the form displays the control on the form when I use the preview browser.

    As long as I have CF tag which is the code on the server side that have no controls on the form.

    I thinkg I missed something when I have both control code and the server of the client on the same form.

    I would like to know how I can show the controls on the form and the CF tag for code running on the server side.

    For example, I have a user name and password text box on the form.

    I need to validate the information user and need of a stored procedure that is executed when the user clicks on the "connect" button.

    I have 2 text boxes on the form and it works.

    As soon as I have the CFSTOREDPROC tag then the shape does not shows the controls.

    It seems the form to run sider server code, but client side of the code does not run.

    Your information and help is much appreciated,

    Kind regards

    Iccsi,

    The form action attribute points to a different file or the same file? If it is different then you can not see the controls because it refers to another file (action file). If this is the same file, then it might have a logic that prevents the form to display after the form submission.

    It would be useful to join the code. So, we could myself or others help you better.

  • Push BlackBerry: Application accessories server-side

    Hi all

    I want to know the application requirements on the server side.

    1. I have a few Notifications in my application.
    2. My application to retrieve some webservices data after a specific interval or manual traction (update).
    3. These data are in the form of JSON, I have to analyze and then use it to display the notification to my application.
    4. Now, if I change the 'Blackberry Push Notifications' draw, what changes should I make to the coast server.
    5. If I'm right, I'll have to make an application Java server-side. Besides, this application will contact My Web services to extract the required data. After obtaining the data, this application will push data (along the device PIN who need push Notification to be sent) PPG by configuring Push service SDK.

    "Please erase me if I'm wrong.."


    Uptill I did :

    1. I'm registered for Push Notification by completing the evaluation form to push Blackberry. And waiting for response from the RIM.
    2. Downloaded the SDK of Service Push v1.1.0 and installed successfully.

    as I have already said, push a short message and allow the client to remove the data.
    Push is to inform, not necessarily to put all the data on the device.

  • Publication of files on the server side is not visible!

    Hello

    I post an image of a device using the following code:

    PNGEncoder encoder = new PNGEncoder(bit, true);
    byte[] imageBytes = encoder.encode(true);
    
    connection = (HttpConnection)Connector.open("url");
                connection.setRequestMethod(HttpConnection.POST);
                connection.setRequestProperty("Content-Language", "en-US");
                connection.setRequestProperty("Content-Type", "multipart/form-data");
                connection.setRequestProperty(HttpProtocolConstants.HEADER_CONTENT_LENGTH, String.valueOf(imageBytes.length));
    
    OutputStream os = connection.openOutputStream();
    String newLine = "\r\n";
    String contDisp="Content-Disposition:form-data; name=\"Image.jpg\";filename=\"Image.jpg\"";
    String contEnc = "Content-Transfer-Encoding: binary";
    String type="Content-Type:image/jpeg";
    os.write(contDisp.getBytes());
    os.write(newLine.getBytes());
    os.write(type.getBytes());
    os.write(newLine.getBytes());
    os.write(contEnc.getBytes());
    os.write(newLine.getBytes());
    os.write(imageBytes);
    os.flush();  
    
    int responseCode = connection.getResponseCode();
    if(responseCode != HttpConnection.HTTP_OK){
        connection.close();
        Dialog.alert("Status: "+String.valueOf(responseCode));
    }
    

    The POST request works very well, but I can't get the file on the server side. The application has no file as an attachment, what am I doing wrong?

    Thank you

    You are not set or a border for the body in several part. In addition, the content-length header is supposed to be the length in bytes of the entire body, including the part headers. I'm surprised that the server isn't hard to refer a complaint.

    Do you need to send this as a request for several part? Looks like you send just a single file. Try to assign the image/jpeg content type and write the bytes of the image in the output stream, with no header.

    PNGEncoder encoder = new PNGEncoder(bit, true);byte[] imageBytes = encoder.encode(true);
    
    connection = (HttpConnection)Connector.open("url");connection.setRequestMethod(HttpConnection.POST);connection.setRequestProperty(HEADER_CONTENT_TYPE, CONTENT_TYPE_IMAGE_JPEG);connection.setRequestProperty(HEADER_CONTENT_LENGTH, String.valueOf(imageBytes.length));
    
    OutputStream os = connection.openOutputStream();os.write(imageBytes);os.close(); // not just flush()
    
    int responseCode = connection.getResponseCode();if(responseCode != HttpConnection.HTTP_OK){    connection.close();    Dialog.alert("Status: "+String.valueOf(responseCode));}
    

    (If you declare your class as long as HttpProtocolConstants of execution, you can use the names unqualified as I did here).

    If you need the file sideways name server, I would send it as additional path added to the URL info.

  • Client/server JavaFX, how FX can do server-side?

    So I am ultimately design a client/server application. Now, I'm curious to know how FX itself can do.

    I know that Java EE is the server side of the platform, while that for the client side (right or...?) so I was curious to know how FX fits inside, just like a RIA (Rich Internet Application).

    I have seen examples such as the application of DataApp that uses the resources of the ERA with JavaFX, so I'm curious to know how, if any, limitations exist for FX.


    The reason I ask is because I'm trying to know where to start with EE and there is so much information it is overwhelming, and I have no idea where to start. It seems that there are a ton of "JSR" for different tasks, and I don't know exactly what I need and that, so I'm really confused: (all.

    Any ideas of how I should go about it would be appreciated.

    Thank you

    Ignore the JSR for now.

    Follow the JavaEE tutorial.
    http://docs.Oracle.com/javaee/6/tutorial/doc/

    The answers to many of your questions will be clear to you when you've completed the tutorial.
    -----------------
    I also like the tutorials here (they are a little dated, but still topical for most as the core of JEE6 specifications that the tutorial relies on have been released 5 years ago and JEE7 has yet to be published).
    https://Schuchert.wikispaces.com/EJB+3+and+Java+Persistence+API
    ------------
    zonski has a targeted spring + javafx tutorial if you prefer to learn and to use spring than JEE (they are different technologies, which cover roughly the same functional game):
    http://www.zenjava.com/series/building-JEE-applications-in-JavaFX-2-0/
    -----------------
    JavaFX is a setting aside of client, so there is not a lot that you would do with it on the side server.
    ----------------

    It seems that there are a ton of "JSR" for different tasks, and I don't know exactly what I need and that, so I'm really confused all

    Nobody needs JEE, just use the pieces that you want that are a good target for any project you do - do not try to use everything at once.
    Many things can be learned and used on its own.

    Some relevant topics, perhaps (in the order I would consider them):

  • You can add server-side in Muse?

    Hello

    I'm working on a design for the customer, and they want to put me a bunch of footer that they use large Office.  I'm testing it in the Muse with the additon HTML object in Muse.

    I first tried:

    <!-#config timefmt = "%A"--> <!-#echo var = "DATE_LOCAL"-->

    Just add the local time at the page and which did not.  Then I tried:

    <!-file = "test.txt #include" - > "

    to see if it will draw a simple text file that didn't work.  is it possible to do with the Muse?  I'm not doing the right way?

    Thank you

    Hi Michael,

    To use the language server side in Muse, you are indeed necessary to insert the code using either the object "-> insert html ' or '-> page properties metadata.

    I would recommend that you create an html page on the server with the code you mentioned above and make sure that the code works and there is nothing wrong with it. Unfortunately, it's not a way at this stage in the Muse to insert the html code near the end of the page. So I can recommend that you place the html embedded at the bottom of the page, however, that is not an accurate way to add something at the end of the page.

  • Display the Server Side includes in top of scrolling Div

    Hello

    In this topic, I will refer to the following containers on my page:

    A: DIV contains the content of the page; This div has overflow, highlight the value.

    B: DIV contains links

    DIV A contains 3 different SSI, each with a different ID. Using the show/hide element, I put it so that when the user clicks on a link in a Div B, the side appropriate server include displays in A DIV, and the other two server-side includes are set to hide.

    The only problem is that when their appropriate links are clicked, ISS 2 and 3 of SSI do not appear in the top of the DIV, but to the position they would be if SSIs all were set to show, then the user must scroll to see SSI and SS 2.

    Know you people anyway to the poster of the SSI at the top of the DIV?

    It occurred to me that instead of use show/hide behavior, I may need to include somehow a SSI only when a DIV B link is clicked, and when a different link B DIV is clicked, that SSI is stripped form on the page and the appropriate SSI are included. Is it still possible?

    Does make sense for you all?

    Thank you

    Mike

    Without seeing your code, it could be how you position these elements on your page.  If you plan on hiding the layers you may set these layers to show at the same place every time by setting the position of A parent DIV and the absolute position of the 3 inner layers with a top and left value set to 0.

    Validation server-side

    When the user performs an action that makes the form must be completed, OA
    Framework proceeds by all HTTP POST treatments - including the execution of all your

    Validation on the client side

    Whenever a form with the data entered by the user sends, UIX performs some basic validation Javascript onSubmit (he
