[PHP-DB] mysql auto_increment
I am writing a catologe application and i have a problem when it comes
to the edit product part. I have a table with the catogories and a table
with manufacturers.
Each table has a id column and a name column. The id column is set up in
the MySQL to auto_increment, which works fine normally, but i am writing
this script:
function edit_cat_radio($item_cat_id)
{
connect();
$sql = SELECT * FROM cat DISTINGT ORDER BY cat_id;
$result = mysql_query($sql);
$k = 1;
while ($row = mysql_fetch_assoc($result))
{
extract($row);
echo 'label for=',$cat_name,'',$cat_name,'input
type=radio name=fcat value=',$cat_id,' id=',$cat_id,'';
if($k == $item_cat_id)
{
echo 'checked';
}
echo ' /';
$k++;
}
return;
}
This should (in theory) automatically check the radio button of the
existing catogory. It would work fine; but what seems to mess it up is
the auto_increment.
If i delete a catogory/manufacturer from the id's remain the same. and
end up like this:
cat_id cat_name
1 Bridlework
2 Clippers
3 Clothing
4 Dressage Tests
5 DVD/Video/Books
9 Footwear
but if the cat_id is 9 the /while /statement doesnt repeat 9 times so
the counter never reaches 9.
I don't know if you got all that, its hard to explain.
I would appreciate any help on how to sort this out.
Thanks

Re: [PHP-DB] mysql auto_increment
I guess this code was not copy pasted from your actual source? It
would generate mysql errors.
Anyway, I think I've an idea of what you want, so here's my two cents :
function edit_cat_radio($item_cat_id) {
connect();
$query = mysql_query(SELECT * FROM cat);
while ($row = mysql_fetch_assoc($query)) {
echo label for=\{$row['cat_name']}\{$row['cat_name']}input
type=\radio\ name=\fcat\ value=\{$row['cat_id']}\
id=\{$row['cat_id']}\ . ($item_cat_id == $row[cat_id] ?
checked=\checked\ : ) . /\n;
}
}

Little change - the label was not used in the right way:
