I am adding a new email address to a database when I check to see that the user If using 

 , then (! ($ ($ $ Stmt = $ dbConnection- & gt; ('SELECT' email_addr 'FROM'). TABLE_NAME. 'WHERE' email_addr` =   
 When I try to run  
  (if (($ ($! ($! ($! ($! ($! ($! ($!) And 'INSERT INTO'. 'TABLE_NAME' ('Email_addr`, `date_subscribed`,` act_code`, `subscribe_ip`) value (?,?,') '))))   
 Error me  unknown column' Email_addr is found in '' field list ''. I tried a lot and thought maybe adding the backix would solve the problem, but it did not happen. If you want more code, please let me know.  
 Solution: There was a typo in constant. Thanks for everyone to ask to run the query, so I searched for the problem.   
 
 
  Unknown column 'email_addr' in the 'Field List'   
 This error indicates that you have a column name Those who are present are not present. Review your table to make sure it's the correct column name and make sure you're using the correct variable in your query.  
 Try removing '`' from the columns you are trying to insert:  
  (email_addr, date_subscribed, act_code, subscribe_ip)   
 Also try to resonate the query and run it directly in phpMyAdmin to see the result. There may be a problem with your formatting that you do not know.

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.

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...
