desc sort - what am I missing?
ok. I am going nuts trying to figure this out. I have a db that I want to put the items in, but show on the page in a reverse order. They then click on the item and that takes him to the actual content.
So I have read a lot of information on this, and from what I read, this is the way to make it happen. Yet everytime I run this script, I get:
"Unable to select info"
What is wrong with this script?
<?php
$username="name";
$password="pass";
$database="db";
$link = mysql_connect(localhost,$u
mysql_select_db($database)
$query="SELECT * FROM table ORDER BY index DESC";
$result=mysql_query($lquer
$result2 = mysql_num_rows($result);
while ($i = mysql_fetch_array($result)
{
$field1=mysql_result($resu
$field2=mysql_result($resu
print "$field1 - $field2";
}
?>

Actually, the script is set as $lquery. I categorize the strings per the area I am working in. This area is the listing area, or the "l" area. So all strings were actually "$lquery", "$llink", "$lresult", etc....
I took all the "l"s out to make the structure easier. I just forgot to change the ($query, $link).
The problem is still there.

Okay, if you are sure that index is different for each record in the table then i am at a loss.
You could always reverse it with ORDER BY index ASC

So this is correct? Maybe I need to add more....
Normally I list things, so on other pages, I have the following code -
$i = 0;
while ($i < $result2)
{
$field1=mysql_result($resu
$field2=mysql_result($resu
print "$field1 - $field2";
$i++;
}
Maybe there is another way to do it.....

Lol oh, maybe that is the problem!!! =)
while ($i = mysql_fetch_array($result)
{
$field1=$result["field1"];
$field2=$result["field2"]
print "$field1 - $field2";
}

Hi,
I think you cannot sort on "index", unless you have a field called "index" in your table. Personally I think you to change the below line:
SELECT * FROM table ORDER BY index DESC";
And have it say:
SELECT * FROM table ORDER BY field1 DESC, field2 DESC"; //sort reverse on field1, and when field1 is equal for two records, sort by field2.

Realize that this is a scaled down version of the code I am actually running. Yes. There is an index. There is always an index on any of my tables. It's also what I use when I cross reference tables.
Nonetheless I have tried to use other fields like field 1, but the result is the same. No change in the desc order. bes

Have you tried using mysql_error?
mysql_query($query, $link) or die(mysql_error())
The problem is not with your php, but with the query.

ok. I did that, and it came back with "Check the SQL statement on line 6 (the Select statement).
I went back to the DB and put in another field called "index2". I then populated it with "1". I went back and changed the SQL to
$query="SELECT * FROM table ORDER BY index2 DESC";
It came back without error, but it also came back without putting any information in the table. The HTML prints out, so it goes through the statement, but it doesn't populate anything.

That did it. Everything is listing the way I want!
Thanks.
Thanks.
$lquery should be $query? Here is your code:
$result=mysql_query($query
