[PHP] Why doesn't the second instance work?
I'm creating a list/menu form item and populating it from a database,=20 the code snippet looks like this: =00 Edit an item: "; echo ""; for ($i=3D0; $i <$num_results; $i++) { $row =3D mysql_fetch_array($result); echo " $row[id], = $row[productname]"; } echo ""; echo ""; echo ""; ?>=00=00 Everything is good, Everything is fine, so I decide to put the same=20 snippet of code in again, this time pointing to a different page -- One=20= page lets you edit the fields, the other shows you the final output,=20 the item from the database featured on a web page. preview an endpage: "; echo ""; for ($i=3D0; $i <$num_results; $i++) { $row =3D mysql_fetch_array($result); echo " $row[id], = $row[productname]"; } echo ""; echo ""; echo ""; ?>=00=00 The second instance does not work, I get a select with "," as each=20 option, no population with the id or productname. Clearly, I don't=20 understand something here, can anyone tell me what?
