I am currently replacing an empty space with underscores during an image upload. How can I include it so that this change is done & amp; "And". 

  $ newname = str_replace ('', '_', trim (strip_tags ($ _POST ['name']))). _ $ FormKey- & gt; Generation () '_' post (). '.jpg';   
 It is stuck with one and does not even know what to try.   
 
 
  $ newname = str_replace (array ('', '& amp;'), array ('_', 'and'), ...);

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.
