Bug description: mysql_query() fails when query works directly in MySQL
Description:
------------
When sending the MySQL query through the mysql_query() function, MySQL
does not send back a result set. But when echoing out the $sql statement
and running it directly into the MySQL database via PHPMyAdmin or another
tool, the query comes back with the intended results. Also, running a
mysql_error(); outputs nothing. So this lead me to believe it was a bug in
PHP.
Reproduce code:
---------------
define("DB_ADDY","localhost");
define("DB_USER","icesnak_eqitems");
define("DB_PW","trademasters");
define("DB_DB","icesnak_eqitems");
function find_item($types,$terms){
if((!empty($types))&&(!empty($terms))){
$types[] = "stock";
$terms[] = "instock";
$dblink = mysql_connect(DB_ADDY,DB_USER,DB_PW);
mysql_select_db(DB_DB,$dblink);
$sql = "SELECT * FROM `items` WHERE `". $types[0]. "` LIKE '%".
$terms[0]. "%' ORDER BY `itemname` ASC";
$result = mysql_query($sql,$dblink);
if(mysql_num_rows($result)){
echo 'Something';
} else {
echo 'Nothing';
}
}
}
Expected result:
----------------
I would expect to get the output of "Something" since there are multiple
rows in the database that match the search criteria. I think this issue
has to do with the use of the "%" wildcard character...
Actual result:
--------------
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result
resource in /home/mystuff/public_html/core/core/EQItems.php on line 73
Nothing
