Update/save record on a single page?

Hi all. I've got a form with read-only fields displaying database data in a repeat region. If I click the Edit button at the end of each line, the 3 fields post to update.php where I can edit the data. The Save button on this page updates the database and returns to the list.  I am new to PHP and was wondering if this can all be done on a single page so all the fields in the repeat region are editable/saveable? thanks guys.

Unfortunately because form field names need to be unique in case, let's say a user edits 2 different forms, making everything editable live is not usually the best way to go.  Personally, from a beginner's standpoint and from a compatibility standpoint, your way is the best way to go.
The only other approach would involve javascript and JSON to pass information between PHP and javascript.  Basically the end result would be a Facebook style post system, where what happens in the background is you actually load a processing and/or editing page and then post results back to the original page.  It's a bit complicated for a beginner.  It might not be for you immediately, but it could always be interesting to learn about:

Obviously that is just for a wall, but if you understand how to edit the pages and how the data is moving it could easily fit your needs.

  • Can't update mysql records from a web page

    Hi everybody,
    I am beginning with Dreamweaver CS5.
    I followed a video tutorial on how to visually design a data entry/update web page for a mysql database using server behaviors.
    My problem is that I was able to insert records and see inserted records but when I try to update a record it doesn't work.
    I don't get any error message, it just redirects me to the listing page as it's supposed to but doesn't take into account the changes I made.
    Below are 2 printscreens along with the corresponding code.
    Can someone help me please?

  • In the mail app why can't I see single page pdf attachment created by SSRS R2 on iPad with iOS 8?

    We have reports that are generated using Sql Server Reporting Services 2008 R2 and are distributed to users by email as a PDF attachment.  This worked fine in iOS 7 but ever since users have updated to iOS 8 the single page PDF is missing even though it has the paper clip icon indicating there is an attachment with the email.  If the PDF is multiple pages then the PDF icon would appear but there seems to be a problem with the single page pdf that is embedded on the mail app in iOS 8.
    We've recreated this issue creating a test report and sent it to iPads that have iOS 7, iOS 8 using different models of iPads (2, 3, 4) and the ones that have iOS 7 work fine.  Only the ones that have iOS 8 have this issue.  Also tried changing the format of the file to a PNG, TIFF and again the same results on the iPads with iOS 7 display it correctly.  Another test we did was send the PDF to our personal email and open it on our home iPads we were not able to see the single page PDF on iOS 8.  Looking at the headers of the email I can see the that the Content-Type is multipart/mixed.  When the original is forwarded to oneself on the iPad the attachment is included but the Content-Type is application/ms-tnef.

    Can you check your email headers, I have also noticed this for reports that are generated using Sql Server Reporting Services 2008 R2. It could to be due to the Content-ID header I believe.
    As a single page attachment on iPad will try and display inline, the Content_ID header is possibly affecting this and showing a small blank square as the image instead. Although this isn't defined as inline within the Content-Disposition header and will appear as an attachment on Outlook.

  • How to use a single page for create and update mode.

    Hi,
    I need to develop a single page to be used for both create and update modes.
    I am going to use a variable MODE
    and i will set this in the emp summary page.
    Based on the button clicked by the user i have to render the JSF page.
    For tis if the user selects a perticular and cliks on update thn i will pass the empno to the next.
    so there in the next i will appy a ViewCreiteria on my View Obj to fetch only that row so that only that emp will be displayed ion update mode.
    This is working fione for me.
    So now the issue is
    when the user clicks on CreatEmp button.
    i need to enable my VO for insert operations.
    for this i wrote the code like this in the beforePhase event
    FacesContext ctx = FacesContext.getCurrentInstance();
    ValueBinding valBinding = ctx.getApplication().createValueBinding("#{data}");
    BindingContext bContext = (BindingContext) valBinding.getValue(ctx);
    DCDataControl dcControl = bContext.findDataControl("DataControl");
    Application app = ctx.getApplication();
    ApplicationModule am = (ApplicationModule) dcControl.getDataProvider();
    System.out.println("After Appmodule initiation");
    // get the VO reference and initiate the query
    System.out.println("Before Page VO initiation");
    PrismDmPageSectionViewImpl vo = (ViewImpl)am.findViewObject("View");
    //ViewRowImpl row = (ViewRowImpl) vo.createRow();
    /* TO CREATE AN EMPTY ROW*/
    Row row=vo.createRow();
    System.out.println("New Row is created");
    //vo.createKey(row);
    vo.insertRow(row);
    vo.setCurrentRow(row);
    By doing this a new empty page is rendered.
    But when i fill up the values and click on ok.. i am getting the error like this..
    JBO-27023: Failed to validate all rows in a transaction.
    JBO-27027: Missing mandatory attributes for a row with key null of type View3
    JBO-27014: Attribute Id in View3 is required
    JBO-27014: Attribute PageeId in View3 is required
    Please point me out where i am missing.
    Thanks

    Hi,
    In my opinion you are over complicating things.
    This is what I do for using the sme page as both create and update without all this code.
    1) Create a browse page containing a an adf table with a select one component bound to your view object.
    2) Create an additional edit page containing only an edit form containing fields of your view object that your users must enter in order to add or edit rows.
    3) Link the pages in the JSF diagram with an "edit" navigation case from browse to edit page and a "return" navigation case from edit to browse (make sure that redirect option is NOT set on both cases)
    4) Remove the submit button from the edit page and add two application module bindings for the commit and rollback operations as command buttons in the form footer facet. Make sure that both buttons has an action of return and that their disabled property is set to false. You will probably change their labels to ok and cancel respectively.
    5) Drop a create action for your view object from the data control palette inside your page as a command button and set the action property to edit also.
    3) Set the action property of the view button to edit
    This should basically work without any code from your part. -- at least it does so for me -- if you like to make it a bit more funcy you may add am action listener inside your buttons and set a requeScope variable for example #{requestScope.editing} to true or false depending on the button clicked. Then add a title to your page with a value like #{requestScope.editing == true ? 'Editing record' : 'Adding a new record'}..
    Hope that helps.

  • How to save ONE single page of pdf document?

    I have a 115 page pdf document that I can open in Adobe Reader. I want to email just ONE page of this file to someone. How do I save just that one page from the file (as opposed to sending the entire pdf document)?
    I know, lame question. Thanks for any help!
    Angela

    If you're on a mac forget about Acrobat on Lion (maybe even Snow Leopard and Leopard too). I ran into this issue on Lion so here I am....
    you have to go through the routine of "printing to",, With Acrobat go to the printer preferences panel > select pdf, select save as pdf... only to find you cannot and get some even more riduclous and useless pop up telling you to chose file save as.... which only lets you save the entire document! Utter
    waste of time and space...and not what you are after.
    Solution... Open the pdf with Preview, then Cmd + P will bring up the same dialog box mentioned above with pdf down bottom left... First enter the page number into the pages option's From dialog... eg From 40 to 40 (= page 40 only) then hit the pdf bitton and dave as,,, Works perfectly with Preview but no chance with Acrobat!!!! I am starting to get the feeling that this product is fast becoming redundant as it seemingly is not up to basic operations such as printing or saving off a single page anymore. Plenty of freeware solutions are now available on the net - some of which I am quite sure would handle this... but since preview is installed on mac by default.... why not?
    After all this have a good think abou whether you will or even need to Upgrade Acrobat the next time round. It seems the more 'advanced' Adobe get the more useless certain products are becoming.... Don't know if it's just me...
    UPDATED Sept 11
    Seems there is a way to print a single page with Acrobat X.. but not at all as straightforward as mentioned above...
    You need to go View>Tools> Extract, then select the page you want and save it as a seperate pdf. Then open the new pdf and print that... Wonderfully intuitive on Adobe' s part....

  • Update multiple records on one page php/mysql

    Hi folks,
    I am trying to adapt a page to offer the option to update multiple records on one page.
    The intention is to edit FAQ categories which are contained in a table with just two fields - the category and an id.
    The page lists each categories in a form with a submit button which is then repeated for each record in the recordset.
    Unfortunately my plan didn't work and only the first record updates as intended.
    Can anyone suggest how I can make it work?
    Here's the code I have so far.
    ************** The Update Code *****************
    $editFormAction = $_SERVER['PHP_SELF'];
    if (isset($_SERVER['QUERY_STRING'])) {
      $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);

    if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
      $updateSQL = sprintf("UPDATE faq_categories SET category=%s WHERE id=%s",
                           GetSQLValueString($_POST['category'], "text"),
                           GetSQLValueString($_POST['id'], "int"));
      mysql_select_db($database_con_mysite, $con_mysite);
      $Result1 = mysql_query($updateSQL, $con_mysite) or die(mysql_error());
      $updateGoTo = "faq-category-edit.php

    What does debugging tell you? What's the value of each of the variables? Did you try using regular echo statements to monitor what's going on? That's what I always do whenever I am stuck in my PHP coding.

  • Getting error " Incomplete update due to error in single records"

    Dear All,
    We are loading data from DSO to Cube using full load and the load is failing giving an error message Collection in the source system ended and when checked the error message button it is showing as  " Incomplete update due to error in single records" . and also one more message "Messages (type E) for data records with record number 0
    Message no. RSM2714". Can any one tell us the reason for the failure of this load ? and how to resolve it ?.
    When we click on the help button of the error message it is displaying the message as below
    Incomplete update due to errors in single records --> Long text
    Message no. RSM2712
    Diagnosis
    In the update rules, one InfoSource record was used to create several records in the data target. These records must be handled in the same way to enable tracking into the PSA and the treatment of errors in individual records.
    In the previous case, one record was updated in this kind of group generated by update rules, whereas other records in the same group were rejected. If you updated the PSA data record again, the records that were already updated would be updated again. Duplicate records would appear in the data target and the data target would thus be inconsistent.
    System Response
    The data record with errors was highlighted in the PSA. However, no error request was generated.
    Procedure
    Delete the request in the data target and, after removing the error, update all records for the request to the data target again.
    Regards,
    JayaKrishna

    hi,
    Can you please check out the PSA error record and check this out in Source DSO as this load is for DSO -> Cube....
    Please correct it in PSA if this is not correct as per DSO ....prior correcting data in PSA pls delete the request from Cube.....then it will allow to correct or delete record in PSA and then further push data from PSA to Target Cube...
    If its correct as per DSO then run load in DSO sometime few records wrongly updated by  end user and they correct it by evening for Submission....So u will get the corrected record and then run manually further load to Cube...
    Hope this will help....
    Regards,

  • Save a cs4 multi page document as single page cs4 files?

    Is there any way to save an InDesign cs4 file with multiple pages as single page cs4 files?
    I do not want to save them as PDF's, or any other file type. I need them to stay as a cs4 files.
    Thank you!

    Not that I am aware of... Try scripting it - or you may find a one already online. Check out http://indesignsecrets.com/. You'll find a wealth of resources there as well.

  • Update multiple records on one page

    I have a page that displays records based on a varible that
    is selected on
    the previous page.
    So on this page i have displaying 3 columns
    Store # Allowance Total
    They have asked now instead of clicking on each indivual
    record to mark it
    as completed, they would like to just place a check next to
    each one and let
    it update those records for that store....
    Ex.
    Store 20 has a total of 7 records and has an allowance of
    $6000.00 then
    they would place 1 check mark next to that store and hit
    submit and it would
    update all 7 records with a status of completed.
    I have read thru some not all but some of the example links i
    found for
    updating multiple records. But they seem more complex than
    what im trying to
    do. Since this page is populated dynamically how can i code
    it so it
    understands when there is new stores listed and records.
    Is there any links or tutorial that anyone would recommend
    that will explain
    the process for creating this functionality?

    My bad....
    ASP and Access is what im using DWMX

  • How to solve showing thousand of records in table in single page.....??

    Hi Guys ,
    I have a table bind to ObjectListDataProvider and using hibernate 3
    i set the pagination rows to 10 per page and enable the paginate button to true
    but i was wondering why the application server or rather the JSF itself cannot handle lots of records displaying in one page.
    for example i have 150 pages for 10 rows per page each
    if i click paginate button to show all in single page , the cpu utilization hit 99% and my application will hang.
    but it works okay if i have 8-9 pages for 10 rows per page and show all of them in single page.
    Is there any way i can fix this or tune this up?
    anyone experiencing this before?
    Thanks

    Solved.
    Somewhere in our code, while populating one of the columns of the table, we were resetting the VO which was causing the issue. Modified that method call to add a parameter to mention from which row should the table be populated.
    Thanks

  • Can iWeb09 update single pages without publishing the whole site?

    Does iWeb 09 have the ability to just update 1 single page without having the need to publish the whole website?
    Thank you

    Really? I've been using iWeb and MobileMe for as long as iWeb has been out, and can't find any option to publish individual pages rather than full sites.
    iWeb '09 does clearly introduce the option to publish a single site or all sites, but as for a single page within that site -- when other pages in the same site may have also changed but you don't want to (re)publish them yet -- that capability eludes me. I'm not at my proper system at the moment, however, and am am just writing from memory.
    Can you clarify, Roddy?
