Hi,
Many databases return their results without table specification.
However, If you have 2 columns with the same name you MUST specify which one
you need in the query, or the database will start complaining about it.
The way around this problem is simple, use an alias in the query, and do not
give the tablenames in PHP.
In your case:
$some_query = mysql_query(
"SELECT table1.id,
table1.category AS cat1 ,
table1.author,
table1.title as title1,
table2.title as title2,
table2.category AS cat2
FROM table1, table2
WHERE table1.category = table2.category ORDER by table1.id DESC");
while($record = mysql_fetch_array($some_query))
{
$mycategory = ($record['cat2']);
$mytitle = ($record['title2']);
echo"$mycategory";
echo"$mytitle";
}
(Not tested)
Good luck and regards,
