getting rows from database with php - nothing returned

Question

So here is my php code:

$result = mysqli_query($con, "SELECT * FROM WW_temp");
$numrows = mysqli_num_rows($result);

if ($numrows!=0){
    while ($row = mysqli_fetch_assoc($result) && $numOfPics >= 1){
        $ImageFilename = $row["image"];
        echo "$ImageFilename///";
    $numOfPics--;
    }
}

The output I am getting is ///////// (9 '/') when numOfPics is set to 3. There is definitely some fields in the column 'image' in the database. Is there anything wrong with the code?

Answer 1

You logic is squiffy. Currently your while condition is interpreted as:

$row = (mysqli_fetch_assoc($result) && $numOfPics >= 1)

So $row == true while there are rows and $numOfPics >= 1 .

Change it to:

while ( ($row = mysqli_fetch_assoc($result)) && $numOfPics >= 1 ){

and it should behave sane-ly.
