// get the list of resellers from the db
$res = mysql_query(SELECT * FROM resellers ORDER BY id);
// print all records in the DB
while ($myrow = mysql_fetch_array($res)){

}?
There's an easier way to display this. It should make your life
easier...made mine.
Take a look:
?
// get the list of resellers from the db
$res = mysql_query(SELECT * FROM resellers ORDER BY id);
// print all records in the DB
while ($myrow = mysql_fetch_array($res)): ?
trtddiv align='center'
font class=content?=$myrow['id']?/font
/div/tdtdnbsp;/tdtd
div align='justify'font class=content
?=$myrow['company']?/font/div/tdtdfont class=content
a href=?=$PHP_SELF??op=resellersid=?=$myrow['id']?delete=yes
(DELETE)/a/font/td/tr
? endwhile; ?
now when I click on delete it just reloads the page and doesn't delete the
record. I have this code before anything else on the page to handle the
delete...
if($delete){
$res= mysql_query(DELETE FROM resellers WHERE id=$id);
header(Location: admin2.php?op=resellers);
}
What you should do here is check to see if $res is failing, simply by
doing the following:
if(!$res) echo error;
Then, place an 'exit;' after the header(...) command to see if the
$delete variable is actually being passed.

[PHP] Re: Deleting a Record
First of all, make a copy of your database to test things. Never test code on production enviroment. Then, the delete syntax most of the time is: DELETE FROM table_name WHERE column = 'value'; Let's see: ?php $table = 'table_name'; $value = '15'; $sql = DELETE FROM $table WHERE field_1 = '$value'; mysql_query($sql) or exit(mysql_error()); ? There isn't a space between field and 1, at least I don't think SQL compliant databases let you put spaces on table and column names. $value probaly should be between single quotes, Mysql requires it for strings or values that are compared to a string type-column (varchar, text, etc...). Even sometimes for numeric columns, so, doesn't hurt to leave it unless it doesn't work ;-) If $table is not recognized, try: $sql = 'DELETE FROM ' . $table . WHERE field_1 = '$value'; If you just want to delete one record, it's a good idea to put a LIMIT 1 at the end. Hope it helps! -- Julio Nobrega.
