Error message is clear, Where you have `$row` defined? – B. Desai Sep 24 '17 at 04:29 — B. Desai, Sep 24 '17 at 04:29

The problem you are having is because you just do not have a $row variable set. So there's where your error comes from. You call it, but nowhere in your code you are assigning it value.

I assume that you are trying to pull your Database records, which should be associated to your $row.

I also assume that you are trying to fetch the associative content from the database, since it is setup as $row['COLUMN_NAME'];. I do not see the code before you call the $row variables, but take a look below.

So to fix your problem look at this example example:

while ($row = $result->fetch_assoc()) {
    echo $row["ImageLocation"];
    //...
}

If you are a procedural programmer, look at this one:

while ($row = mysqli_fetch_assoc($result)) {
    echo $row["ImageLocation"];
    //...
}

For the complete set code look under PHP's manual here. The documentation is good, and it will explain what you need to be doing.
