Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

    Breadcrumbs

    Has anyone been down the path ( :D ) of creating Breadcrumbs within the WAS. (For those who don't know, it's the links to pages previously displayed. See Wiki Breadcrumbs).

    What method worked best for you and was easiest to maintain?

    Re: Breadcrumbs

    Breadcrumbs are a maipulation of the URL string and show the folder structure. I'm not sure they would work in Alpha right now given you cannot have two or more "index.a5w" pages in sucesesive folders (if you have Security Framework turned on). You'd need a default page like index.a5w to open for each link, in each folder. Or you would have to do some fancy coding to define what page to open at each level.

    Breadcrumbs take a URL like www.alphatogo.com/level1/level2/mypage.a5w and change it to Home >> Level1 >> Level2, with each being a hyper link to a default page in that folder.

      Hi Steve,

      The breadcrumbs are not really a folder level, but are the links back to previous pages that allow you to navigate back to previous pages you were on (as if you were doing a back key in a sense on a browser)

      So you might have

      login > main page > search results > item 3

      Even if the pages needed to be regenerated, it would be able to go back easily when an unproductive path had been taken

        Re: Breadcrumbs

        I know them as an expression of folder hierarchy and I just checked random web pages and they all say the same. Breadcrumbs of 'pages you have visited' would grow to an undetermined length as your user browsed around; unless you scripted their choices.

        You could name each A5W page like pgname="Search Page" and then assign it to a session variable that carried through to each successive page.

        session.bcrumb = session.bcrumb + ">>" + pgname
        ?session.bcrumb

        You can use Request.Referer to capture the previous page URL; but again you'd have to figure out how to assign a short value to it like "Search Page" otherwise it will be the full URL. I don't know, something like this on each page would show the full URL(s).

          Ira,

          I was browsing the forum when I realised the breadcrumbs here have nothing to do with the directory structure. Searching the web again, I see there are two distinct types of breadcrumbs: 1) Position breadcrumbs which do mirror your directory structure, and 2) History breadcrumbs which show where you have been. Here is a page that covers both types: http://www.whitford.id.au/webmonkey/...crumbs/php.php. Unfortunately I cannot follow the javascript or PHP to determine how they work.

          By looking at the source on our own forum, I can see that the breadcrumbs are done with PHP code, not javascript or some HTML trick.

            Re: Breadcrumbs

            Am looking at the possibility of creating breadcrumbs in Alpha - ver 9 - the kind which will display where the person has been to get to the current page. Has anyone done this successfully and if so could you post how you approached the solution.

            TIA,

            Dorothy

              Re: Breadcrumbs

              I realise this is an 'old' thread. Using v 11.0, I'm wanting to create a simple breadcrumb trail just below the (horizontal) nav bar on each page, and above the body content. Has there been any update on this subject since this thread started? Anyone with any idea how/where to do this?

                What is the nature of the pages in crumbs? Are they just the a5w page name or pages with parameters in the url or pages where the user seleceted some record in a grid and you need the crumb to take them back to that exact record?

                Additional question: if they go from Home to Products and then click on About Me, do you want the breadcrumb to be Home > Products > About (their literal path), or Home > About, the more logical path.

                Describe how they would work.

                  Describe how they would work.
                  By "breadcrumbs" I mean a navigation aid used on all pages in my website. It allows users to keep track of their locations within the website. They would appear horizontally across the top of each web page, below title bars or headers. They provide direct links back to each previous page the user navigated through to get to the current page.

                  eg Home page > Section page > Subsection page or (using page title) Home > Catalogs > Wheelchairs .. I assume this what you refer to as the 'logical path', that's what I need.

                  I hope that's what you are wanting? I can't find anything to do with this subject in Alpha. BTW, I am using your Framework 3 if that is relevant to the discussion.

                  Thanks for your help.

                    I am using your Framework 3 if that is relevant to the discussion.
                    Yes relevant in that I can add a function to the Framework that you can just stick where you want the breadcrumb to appear.

                    Breadcrumbs make sense for something like Home > Catalogs > Wheelchairs; that is a proper hierarchy within a product list. But breadcrumbs look a little silly when they are Home > Products > About > Terms and Conditions > About > Home > Contact Us -- which could easily be the path they take through your system. I think what you want is breadcrumbs that are ONLY applicable to a specific groups page pages, the ones involved in the product list for instance. You don't care about their visit to About or Contact Us as far as the breadcrumbs are concerned.

                    Plus consider, is "Wheelchair" a real a5w page that is named WHEELCHAIR.A5W or is it really page named PRODUCTS.A5W that has a parameter such as "products.a5w?category=wheelchair". Or, if you are using an Ajax Grid to display records for Wheelchairs, is the page named products.a5w which contains a grid named products and the user happens to be on page 4, record 10 which happen to be Wheelchairs.

                    Ajax grids make it difficult to "go back" because there (normally) is nothing special in the URL to take them back to page 4, record 10. I know how to do this (provide a parameter in the URL to "go back" to any specific record, but it takes some Arguments and client-side event code.

                    So in your example, would you have a page named WHEELCHAIRS.A5W or something more complex like I described.

                      That's exactly what I'm wanting. Each page in each section will be named. The hierarchical tree is only 3 deep.

                      Would certainly welcome the function to do this.

                      Thanks
