text in result instead of number returns mysqli unknown column error - mysqli

Question

print_r($cfs);
Array (
[0] => Array ( [0] => MST Ice P [1] => MST [2] => Ice )
[1] => Array ( [0] => MST Ice P [1] => MST [2] => Ice )
[2] => Array ( [0] => MST 298 P [1] => MST [2] => 298 )
[3] => Array ( [0] => MST Ice P [1] => MST [2] => Ice )
[4] => Array ( [0] => MST 302 P [1] => MST [2] => 302 )
)
here is my mysqli:
for($i = 0; $i < count($cfs); $i++)
{
$con->query(
"UPDATE gages SET cfs = {$cfs[$i][2]}, modtime = now() WHERE usgs =
{$stano[$i][1]}")
or die($con->error);
}
Here is my error:
Unknown column 'Ice' in 'field list'
This works fine in the summer when there in no ice.

Answer 1

If as you say the cfs column is VARCHAR then it should have been coded like this with single quotes around the value.
I dont see how it ever worked without them.
for($i = 0; $i < count($cfs); $i++) {
$con->query("UPDATE gages
SET cfs = '{$cfs[$i][2]}',
modtime = now()
WHERE usgs = {$stano[$i][1]}")
or die($con->error);
}
