We are pleased to announce our improved website. We've updated it to
have a cleaner, more modern look, improved existing features and added
some new features as well.
Let's take a quick tour of the Products section. The first thing
you'll notice when you click on the Products link is that the product
categories have been updated. This is now consistent with our 2010
Color Catalog. The second thing that you'll notice is that the products
may not be listed alphabetically in their respective categories. The
products are now ranked by the most clicked on to least clicked on. In
other words, our most popular products are listed at the top of each
category. A third thing you may notice is that there's an Equipment
section. All of the products listed in the Color Catalog's Equipment
section can now be found here along with a picture.

The insertion of the above text falters after "Let's take a quick tour

Are you sure?
mysql> select * from users where name=rlerdorf;
ERROR 1064 (42000): You have an error in your SQL syntax; check the
manual that corresponds to your MySQL server version for the right
syntax to use near '��rlerdorf��' at line

mysql> select * from users where name="rlerdorf";
Empty set (0.03 sec)
As far as I can tell, MySQL does not treat those odd quotes as regular
quotes anywhere.
Please provide a standalone test case along with your MySQL version
that shows this.

Description:
------------
None of the escaping functions are able to properly handle style
quotes, which are produced by default by open office. Functions that I
have tested include mysql_real_escape_string, htmlentities, addslashes
and addcslashes. This behavior causes text insertion into mysql to fail
as it interprets these quotes as normal double quotes.
Reproduce code:
---------------
$title = $_POST['title'];
$date = $_POST['date'];
$tagline = $_POST['tagline'];
$article =nl2br(htmlentities($_POST['article'],ENT_QUOTES));
//<snip of some file handling>
$query = "INSERT INTO news (title, date, tagline, article, image,
image_orig) VALUES ('$title', '$date', '$tagline', '$article',
'$image',$image_orig')"
Expected result:
----------------
The should be caught, escaped properly and not affecting the query.
In this case $article was the varible containing the quotes in question.
Actual result:
--------------
All text after the opening quote is dropped from the data inserted into
the query.
