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.

Integrating Alpha with Facebook "likes" and "shares"

  • Integrating Alpha with Facebook "likes" and "shares"

    When a page is "liked" (or"shared") on Facebook, a pop-up is presented that presents 3 pieces of information that then comprise the share in the timeline 1. Title 2. Content and 3. Image. These are set in the <head> section with tags that look like
    Code:
    <meta property="og:title"content="myTitle"/>
    The problem is that AA "pages" are created dynamically by the AA server. Sure, you can put generic info on the A5w page and that works fine but the "pages" are dynamic. Example: a realtor wants to allow the liking of listed homes. A "like" should have the info associated with that listing. But, all listing would still be on the same A5w page and the "scrapper" would not see the content for each house. Also, though I know there is place for "header tags" in component properties, I do not know if the content can be set to dynamically take {field names} like a freeform edit container and if they would then be served by A5 when a page request includes a page variable - ?variable=field. Of course, content management systems solve this by serving fully formed dynamic html pages with no callback after html render.

    I know this is way out of Alpha's wheelhouse, but does anyone have any suggestions on integrating AA with FB so that dynamic content can be seen by FB and appropriately identify pages for sharing and liking?

    Re: Integrating Alpha with Facebook &quot;likes&quot; and &quot;shares&quot;

    Update: I did a test hard coding a title tag in the <head> tag in a component and set it to pre-render. The Facebook scrapper did not pick it up, which makes sense when I realized that the component header is actually the header of an iFrame on the A5w page.

    So, I don't think this will ever work unless Alpha incorporates a "dynamic page" creation function. This would be a major change from how alpha works and I do not believe it is likely any time soon.

    Still way open to thoughts.

        Steve, thanks for the reply. I was actually hoping you would as I thought if anyone had licked this it must be you. Question though, I see the social buttons in the pic you attached and I see how that is an easy way to add sharing. What I am asking about though is the pop-up after you select share. Here it is from AlphaToGo.

        The problem isn't getting the share to work. The problem is getting the share to display the correct information on a page whose important content is dynamic. The question is how to control what is in that box on a page that looks like www.mysite.com/page1.a5w?id=7 where the important info(image, description and title) should come from record 7.

        I did some inspection of your code and I see that you have not included any meta property tags and facebook is inferring the content from your traditional tags.

        You can see what FB scrapes from your site at: https://developers.facebook.com/tools/debug/og/object/

        Yours looks great even without the Meta property tags but this is a home page without dynamic content. if you opened a component on this page, the scrape would not see anything from the dynamically generated content.

          I guess I have a little modernization to do on my own sites..

          If the user goes to *www.mysite.com/page1.a5w?id=7* then the dynamic content including Facebook metatags would also need to be rendered.

          I found a reference at https://developers.facebook.com/docs/sharing/webmasters

          That AlphaToGo site is really old now; a better example is my Framework. It gets the metatag values dynamically from a table, unique for each page. Example code in the header is:

          ?"<meta name="description" content="" + wt_page("description")+"">"

          wt_page() is my own function that gets values from a table based on the name of the A5W page. Simplified, it would get the results from this query (using description as the example):

          sql = SELECT description FROM pages WHERE pagename = 'mypage.a5w'

          For simplicity, you can just use sql_lookup() where you want to populate the values. Example to a Products table, dynamic for id=7 would be:

          mydesc = sql(lookup("::name::conn","product","id="+request.variables.id,"description")
          ?"<meta property="og:description" content="" + mydesc +"" />"

          (I did not test the above code, check for syntax)

            Check the syntax! I guess I can try though I have never used code like this to set a property.

            Question though. Does your framework deliver pages as mypage.a5w?name=greatpage or as greatpage.a5w. The reason is I don't think, even if the tags get set properly, that FB would pick it up as I don't believe the scrapper allows any script but just looks at the raw HTML. Have you tested any of your dynamic pages in the FB URL checker?

              BTW Steve, you and I had a spirited discussion on here several years ago about using Alpha for a public website as opposed to as an internal app. I was not a believer but you insisted it was a great idea. You were right and I am building a public site (as much for fun as anything else) and I think it looks pretty good with the new tools Alpha has given us. It is end stage beta and I am ironing out the last few issues. micropacs.org The target I am trying to share on facebook is Micropacs.org/campaigns.A5w?Campaign=reallydonald And, I need to pick up specific info from the page including the campaign logo as the meta content "image."
