ColdFusion files downloaded with several attribute in the tag input processing

Hello, all,.

(For the first time), I try a function which will be posted via HTML5 form from one code files < input type = "file" multiple = "multiple" name = "images" / > tag.

Specifically, how do I determine how many files have been selected for download on the side Server?

The goal is to use CFFILE to READASBINARY the images, and then insert that the directly into a MySQL database.  (That last part, I think I have down pat.)

V/r,

^_^

OK... It's CF10, so I don't have the luxury of form definition to present several elements (such as check boxes, boxes option or others who submit a list separated by commas of data) in a table instead of a list... However...

What I've discovered, is that file multiple entry shall submit a list separated by commas of the files.

So what I learned is that if the form is present, use REMatchNoCase() on form.fieldnames looking for the name of the input file element and the length of the array will be the number of downloaded files.


    
    
    There are #arrayLen(results)# files being uploaded.

The downside of this VERY simplistic code is that the form element exists even if no file is selected, it will always display at least one.  Adding validation to make sure that one has the other thing that an empty value would be a good idea. but for brevity, I'm not add that here.

HTH,

^_^

  • problem update to bind a member with an attribute using the rule of load

    Hi - I'm trying to update an existing Member with another attribute of the dimension of the attribute by using a load rule. In the properties to build the dimension, I have the name of the selected member where it says size. Underneath, I field Type, here, I have the dimension of the selected and then attribute below I have the number 0, to match with the child member, I'm trying to update for.

    I am able to validate the rule, no problem, but when I run the update plan, my attributes for this member does not update. This happens to all of my attributes.

    I'm on Essbase 7.0.


    Thank you

    You should (at least) two columns in your rule of load. The first column with the names of members of the basic members you want to associate attributes to and in the second column of the attribute member name.
    If the dimension build properties for the first column, you set the name of the dimension and type of build level or generation (I suggest level) and set the number of levels. (Do not forget the dimension properties build to build level or you will get an error)
    The second column, select the dimension then go down and select the dimension of the attribute that is associated with this dimension of the base

    For example for the Basic sample, you may have a line that looks like

    100-10 can

    For the first column, you would select Dimension = product, value of Type level = 0
    The second column would Dimension = product Type = attribute dimension Pkg Type

    In the dimension settings, make sure product is set to build level and can associate attributes and allows you to change the link.

    You will need to add several attribute to all the 'teacher' in the XML tag.
    I am able to add a single using attribute

    Select insertChildXML (donnees_xml, 'game of LINES/LINES/TEACHER', '@age', ' 37 ") of test_xml_table;

    Thanks in advance

    In this scenario, we have a simple find and replace the XML function using which i can replace the tag with (I understand this is not good was to solve this).

    Why not use two calls separate insertChildXML?
    The premiera adds the attribute to @age, and the other adds the attribute @subject on the result of the first.

  • Automator: using a text file to set several items from the finder?

    Hello

    what I would do:

    I have a text file that contains multiple entries for files and folders, each on a separate line. I want to dragndrop this file on an automator action, he should ask me a destination folder and then copy all the files and folders in this folder.

    I have my action, automator, set up like this:

    Elements of the open Finder

    Get the content of the TextEdit Document

    Copy to the Clipboard (I have not found another way to keep my text sort file values and let it not be crushed by the following, but it works)

    Quit the Application (TextEdit)

    Ask the Finder items (this requires a destination folder)

    Set the value of the Variable (Destination)

    Get the contents of the Clipboard

    Copies the items from the Finder (at Destination)

    It all works, but only when there is 1 entry in my text file. As soon as I have 2 lines of text, I get the following error message:

    The action "copy Finder items" has not provided with the required data.

    How can I make this work with multiple entries?

    The problem is that you only pass the only element to the copy action (you have copied text), instead of an element for each line (paragraph) in the text.  The solution is to use the action filter paragraphs to break up along the borders of paragraph text, which will give you a list of items.  In addition, you do not necessarily have to use TextEdit or the Clipboard - If you already have a file somewhere, you can simply use the action to combine text files to read the text.

    With the above modifications, your workflow should look like:

    Ask the Finder items  (ask for a destination folder)

    Set the value of the Variable  (Destination)

    Ask the Finder items  (Download text files) - set the action to ignore the entry

    Combine text files  (read the text files)

    Filter paragraphs  (paragraphs which are not empty return)

    Copy the items to the Finder  (at Destination)

  • Files downloaded suddenly began to have the wrong group permissions

    I'm on a 10.7.5, using FireFox 24 Imac.
    Suddenly, all the files I download through FF could be consulted from anywhere else in the network, except my Imac. I finally checked the permissions of files downloaded to find that FF began to restrict group access (anyone = no access). Never had this problem before. Somehow FF started obeying does not target folder permission settings.
    I tried a lot of bugs, I even deleted FF with all its relevant files... done a clean install, but the problem won't go away. Important to note that Safari and chrome still download all files with correct group permissions.

    Happy to report this very annoying problem is now gone.
    I've just updated to FF 25 and now the permissions on uploaded files are back to normal, with authorized access group.

  • several attributes in the box?

    Apex 4.2

    I have a classic report with a box... I want to be able to disable the checkbox value is assigned to another column in the report.

    I would also like to call an onchange event to disable some buttons if it is enabled.

    I can get each of these actions to work separately, but not both at the same time.

    I have created an example query below with the emp table. Can't seem to put two attributes in the apex_item.checkbox2

    Does anyone know how to do this? whatever action I put everything first is executed and the second action is ignored.

    Decode(DEPTNO,10,'disabled=disabled',null) OR 'onchange = "spCheckChange (this)",')

    Select empno, ename, job, mgr, hiredate, sal, comm, deptno, apex_item.checkbox2 (1, empno,)

  • deployment of a BPM Application large Oracle with several projects of the user interface

    Hello world
    I'm working on a large application with Oracle BPM 11.1.1.5.0.

    I use JDeveoper 11.1.1.5.0 to build the application.
    The application has many tasks user with a lot of the UI (one for each task of the user).

    My problem is, whenever I make a small change in the project, I need to deploy this, which includes a master project and five or six projects UI (for now) for tasks of the user.
    As demand grows, I'm sure that this will certainly become a problem.

    So my question is if I do this the good sense? or should there be a more effective way?

    Thanks in advance

    Published by: luke on April 17, 2012 12:16 AM

    Hi Luke
    1. as a general rule, there is NO need to have a user interface project for an individual task. As initiator, approver, reviewer, LegalApprover etc etc, you have like 10 tasks (.task files). You can have just a single project of TaskForms UI and have taskDetails.jspx generated for each of these tasks. This is appropriately.

    2. any Application workflow must have only 2 deployers. Deploy resources are for real Workflow stuff that will have the main BPEL or process, BPM, human tasks etc. Basically, everything that goes into the workflow project. And another official of the deployment is that the REST of things means that the UI TaskForms project and other project support as useful projects, WebServices, EJB projects (if you have Web services). All this will be deployed as a SINGLE EAR.

    Lets take an example JDeveloper IDE point of view.
    1. application Name: SalesOrderApp
    2 workflow project name: SalesProcess (he is a a project jdeveloper project SOA or BPM Project type and has all human tasks, bpels, process bpm, rules etc.).
    3 interface user Project: SalesTaskForms (it is a form generated automatically for the first task you choose. Then for the rest of the tasks you can use this same project, to generate jspx for all others. WORK files. VIEW documents online on how to do it. I'll see if I can compile this list of URLS for you).
    3. support the EJB projects: MyEJBProject1 (some EJB project that connects to some specific to your back-end database project)
    4. support another Service EJB project: MyExtServiceProject1 (as another project EJB that uses data from an external source)
    5. some WebService project: SalesCreditCardValidationWebService (some WebService project to be deployed as. WAR file that performs a service).

    Try to apply the Concepts of SOA for each Service your application needs. Instead of putting all the EJBs and everying in one giant project, try to split their need logically commercial/sage and geenrate separate projects so that they can maintain as it is to other projects and other applications.

    Anyway, coming back, in the example above, you should have deployment just 2: 1 is the JAR file of SCA in the Workflow and another complete of the EAR file.
    (a) for the workflow project, right-click and generate a deployment profile to deploy all the workflow and NOT on the other projects of the user interface.
    (b) for each project individual genereate a profile of deployment such as MyEJBProj1, MyEJBProj2, MyWebService1, etc etc.
    (c) for TaskForms project, generate a deployment as SalesTaskForms profile. It is a WAR file.
    (d) at the level of the Application, create a new profile of deployment of the EAR type and now assemble all the projects in this EAR, with the exception of the Workflow project.

    First of all, you deploy file JAR of SCA of the Workflow. You need to redeploy this again only when you make changes to the workflow, humantasks etc etc.
    Deploy the full blown EAR file that has all the stuff (EJB JARs, TaskForm WARs, WebService wars etc.).

    At any time, you change your code taskforms or redeploy a java, ejb, EAR file.

    You should have a POT and an EAR to deploy at the end of the day. Infact this is how it should go into UAT, and production. They may not have many pots, multiple wars deployed. The reason why we have separated Workflow SCA Jar file is, because the workflow will not change frequently. And also older versions of SOA/BPM (before 11.5 FP) have a huge disadvantage. Whenever we deploy a workflow project, it will make existing processes VITIATED, unless you deploy a different version. This isn't a problem anymore for 11.5 + FP (Feature Pack applied). Therefore, be careful when you redeploy workflow project.

  • Appeal with several parameters of the URL

  • Several Conditions on the stage of processing of forms?

    You are allowed to set several options in the Conditions of implementation of a conditional processing step Editor. However, unlike filters in a Segment, the Conditions Editor doesn't tell you if the conditions are joined by 'and' or 'or '. So in the example below, step run, for anyone who enters their State as the Georgia or Florida? Or would look of someone who had both the Georgia AND Florida as a State and, since you can't have both, not run processing step?

    Conditional_Form_Processing_Steps.png

    Thank you.

    If you try to 'OR', depending on the processing stage, you can try to use the option "use a drop-down list to select... "on the stage of treatment rather than using the option under certain conditions. Using a drop-down list, you can download a list of States (like your model) under the name of the Option, then the code active for e-mail, landing page, shared list, etc. for the value of the Option. This avoids the multiple processing steps using different conditionalities.

    Just download the ID and the values in a list of successful selection

    For emails and landing pages active IDS are easy to find using the URL that is displayed when you have open in Eloqua:

    https://secure.P03.Eloqua.com/main.aspx#landing_pages&ID= 115


    Update processing step to «Use a drop-down list to select...» ", select the form field and the managed choice list you downloaded.

  • OIM 11 g R2: target setting dependend attribute on the type of process (create, update, disable)

    Hello

    I try to set an attribute ('Action') of users on a target system (Lotus Notes) dependend on the type of process which was conducted:

    When the user is created in Lotus Notes by the IOM, 'Action' should be on the value 'create '.

    When the user is updated in Lotus Notes by the IOM, 'Action' should be on the value "update".

    When the user is disabled in Lotus Notes by the IOM, 'Action' should be on the value "disable."

    What would be the best way to achieve this? And exactly how I should implement that? (I tried to read the documentation on the tasks of the adapter, however I could not get that to work...).

    Thank you!

    M

    Hello

    Its easy to accomplish by using adapter process task.

    (1) create a field on your form of process as 'Action '.

    (2) create a new process task in Lotus Notes process definition for "Action Updated" (you can use OOTB adapter for mapping purposes)

    (3) create a new task adapter process that fills that takes input like input1 and back to the entrance.

    (4) create the 3 tasks in process in Lotus Notes process definition. One for each action. For example: Update Action such as activate, Action such as disable update, update Action as Create. In the tasks of each process, pass the entrance as enable, disable and create respectively.

    (5) to map each tasks created in step 4 success of Create User, user, user disable respectively.

  • Concerned by several users, reading files interfering with write access to the files

    I have a LV MY application that will run in several places/computers. Each will create a single HTML report and update frequently. These HTML files will be accessed and combined by another application of LV in a new HTML file that will be updated frequently. All HTML files could be opened by a user at any time in a web browser.

    What concerns me, it's HTML reports could be avoided by a user, or the application of the combination to be written by the app MY? If the user or application combining a box open report she always written by the app MY? It goes the same for the app combining prevented to be written if a user has his open output HTML code?

    Each HTML file can only be written by an application but read by many potential users and/or an app.

    All programs run independently and asynchronously. Each application runs on its own computer and files all exist in a network location.

    Can I do this by controlling all users file privileges? If anyone has read only permissions except the written computer the HTML file that will be enough?

    Thank you

    Judd

    I guess as long users see the reports with a web browser, it should be no problem.

    Browsers Web do not "lock" a file when they open it like Word or Excel because web browsers are not and should not modify or change the file somehow.

    If only one person could display a web page to internet time would not work as we know it.

    But if you're worried about it use LabView to lock files during execution of the program. Only in this way, users can open the file as read-only if they use something that can change the files. If you use the standard LabView open file read/write vi passing a file reference, then this will be done automatically.
