    OR mysql search problem

    I've built what I think is a pretty cool and quirky db. 1 table with 4 columns. The columns are a, b, x, and y. A is basically a list of names. B gives info about those names. Very simple. db_table is searched through:
    PHP Code:
    $sqlsearch "SELECT a, b, x, y FROM db_table WHERE a LIKE '%$ask%'"
    It works fine. But because content in column a isn't widely known, I can't really expect people to know what they can search for. So I thought to make db_table searchable by column b, too. Column b basically gives info on the characteristics of a.

    PHP Code:
    $sqlsearch "SELECT a, b, x, y FROM db_table WHERE a OR b LIKE '%$ask%'"
    The problem is that this doesn't work for every a. There are terms that mysql_query gives 0 results.

    I also want to mention that the material in column b include parentheses, commas, dashes, \n, etc. To include an example of an entry:

    PHP Code:
    ('Adam''Adam has a mom.  Adam's mom once said"I took Adam and his friends for breakfast - sit was fun.\n We also went to the movies."\n', 'x', y, 0); 
    0 is for a page_views column that phpmyadmin sets up. I use utf8 for db_table.

    Is it possible the variety of characters in b is the reason why the db_table doesn't get searched properly when I use OR?

    varchar is used.

    I'm no SQL expert by any stretch, but aren't you supposed to escape the single and double quotes? That might be the problem.

    You almost had it right, you just needed to have two like sections a like OR b like.
    This should work
    $sqlsearch = "SELECT a, b, x, y FROM db_table WHERE a LIKE '%$ask%' OR b LIKE '%$ask%'";
