Error while trying to retrive the username in an iFrame facebook application -

September 15, 2013

I am developing a Facebook application with IFRAME RENDERER method. So to display my name, I used the serverfbml tag. This is my code:

  & lt; Fb: serverfbml style = "width: 760px;" & Gt; & Lt; Script type = "text / fbml" & gt; & Lt; FB: FBML & gt; & Lt; Fb: name uid = '$ user_id' useyou = 'false' & gt; & Lt; / Fb: Name & gt; & Lt; / FB: FBML & gt; & Lt; / Script & gt; & Lt; / Fb: serverfbml & gt;

But the output is "Facebook User" Please explain to me why I get such output.

I echoed my $ user_id, and this ID displays.

According to the default text to display, if you can not see that the user facebook user < / Em>.

You can specify the second ifcantsee text to display with such property:

& Lt; fb: name uid = '$ user_id' useyou = 'false' ifcantsee = 'this user can not see' & gt; & lt; / fb: name & gt;

Says:

The wallet to display To specify an empty string instead of default, use ifcantsee = "" if the logged-in user can not access the specified user. The default value is Facebook user

< / Html>

I currently have a database in which the short URL is placed with the actual URL and this click count will ideally update the click count column when that small URL is accessed by an external user. In short, I am looking for a PHP / MySQL solution so that many small URLs can be clicked. . Any additional information gathered from the clicks will also be highly appreciated. I'm assuming you followed the PHP version of your tutorial. If so, look at listing for service.php under "service of small URL". In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

I have two tables: gallery id | Name | Details Image ID | Title | Caption | Gallery ID By listing all thumbnails or paging through thumbnails I got the code to create a simple image gallery. However, what I need to do is here something like gallery here Only completes without javascript and ajax: I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image. How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ... I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
