Accept Multiple inputs with php to update a mysql database -


I am working on a small project: a small number crunching game.

I want a php file that can accept input and interpret them in specified database updates.

Even so far I have this. This is not working for me. 

  $ name = $ _GET ['n']; $ Action = $ _GET ['A']; $ Result = mysql_query ("Select * from players, where username = '". $ Name "."');); While ($ line = mysql_fetch_array ($ result)) {if ($ action = "rankup") mysql_query ("Update player set level 'level + 1' where username = '". $. "". "" "); } Mysql_close ($ con);   
 I have not found any errors, but it is not working, and all database connections are fine.  
 I do not know what the problem is.   
 
 
 Here are many mistakes:  
     
  •  You do not have to do your input About, please read  
  •  You are not checking the output of your  mysql_query . The query with the  SET level 'level + 1'  is invalid, you forgot  =  and delete the quote  
  •   $ action == 'rankup ', not  =   
  •  Please consider using it for new projects, this is a better interface than the  mysql _  functions.

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
