Are HTML encoded special characters required to end in a semicolon? -


is considered the right encoding for & amp; # 8212; , although the semi-colon is left to it still displays properly in my bowers (Chrome and Firefox).

In addition, I am using several email clients to test character encoding. It has been learned that almost all the semicolons are ignored when displaying special characters with the exception of Gmail (IE, Chrome and Firefox).

So my question: are the HTML special encodings encoded to end in semicolon? It seems like Gmail is playing by the rules, while everyone ignores the required semi-colon.

From SGML based HTML to version 4.01, it is possible to eliminate the last ; See .

Note. In SGML, the last ""; In some cases after the reference of a character (for example, just on a line segment or just before a tag). In other circumstances, it can not be eliminated (e.g., in the middle of a word). We ""; In all cases, the character must be present in order to avoid problems with the user's agents.

However, states need to end the character references with semicolons. To prepare your existing site for HTML5, I suggest you end the reference with a semicolon.

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...
