Working with PHP, MySQL and UTF-8


Heres a list of actions you should do in order to get PHP + MySQL working with UTF-8:

1. Database:

CREATE DATABASE db_name
CHARACTER SET utf8
DEFAULT CHARACTER SET utf8
COLLATE utf8_general_ci
DEFAULT COLLATE utf8_general_ci
;

or if the database was already created:

ALTER DATABASE db_name
CHARACTER SET utf8
DEFAULT CHARACTER SET utf8
COLLATE utf8_general_ci
DEFAULT COLLATE utf8_general_ci
;

CREATE TABLE table_name(

)
DEFAULT CHARACTER SET utf8
COLLATE utf8_general_ci;

Or if the tables are already created:

ALTER TABLE tbl_name
DEFAULT CHARACTER SET utf8
COLLATE utf8_general_ci;

2. Enable this line in php.ini:

extension=php_mbstring.dll

and configure the following in the same file:

mbstring.language = Neutral
mbstring.internal_encoding = UTF-8
mbstring.encoding_translation = On
mbstring.http_input = auto
mbstring.http_output = UTF-8
mbstring.detect_order = auto
mbstring.substitute_character = none
default_charset = UTF-8

3. Use the following php functions instead:

mail() -> mb_send_mail()
strlen() -> mb_strlen()
strpos() -> mb_strpos()
strrpos() -> mb_strrpos()
substr() -> mb_substr()
strtolower() -> mb_strtolower()
strtoupper() -> mb_strtoupper()
substr_count() -> mb_substr_count()
ereg() -> mb_ereg()
eregi() -> mb_eregi()
ereg_replace() -> mb_ereg_replace()
eregi_replace() -> mb_eregi_replace()
split() -> mb_split()
htmlentities($var) -> htmlentities($var, ENT_QUOTES, ‘UTF-8’)

4. Use headers and meta tags like:

header(‘Content-type: text/html; charset=UTF-8’) ;

<meta http-equiv=”Content-type” value=”text/html; charset=UTF-8″ />

5. add charset to form

<form accept-charset=”utf-8″ …>

6. Before any insert / update in the database you should perform the following:

mysql_query(“SET NAMES ‘utf8′”);

or use this before making DB connection

mysql_set_charset(‘utf8’);

jQuery – Remove Extra Newline in Textarea


case:

createOnEnter: function(e) {
  if (e.keyCode == 13) {
    items.create(this.newAttributes());
    this.$("#create-item :input").val('');
    this.$("#create-item :input")[0].focus();
  };
},

solution:

Default behaviour of the Enter key in a textarea is to add a new line. To prevent this action occurring within the createOnEnter method, add e.preventDefault(); after matching the key press as the Enter key.

createOnEnter: function(e) {
          if (e.keyCode == 13) {
            e.preventDefault();
            items.create(this.newAttributes());
            $("#create-item :input").val('');
            $("#create-item :input")[0].focus();
          };
        }
