if there or not

I am having a problem.

 

$pic = image.jpg

pic2 =

pic3 =

 

pic2 and pic3 there is nothing in database

 

$query = "SELECT * FROM `cinvent` WHERE `oname`='$loggedin' and iid='$iid'";
$result = $mysqli->query($query) or die($mysqli->error.__LINE__);
while($row = $result->fetch_assoc()){

if ($row['pic'] == 0 ) {
echo "No Image";
} else {
$file1 = $row['pic'];
$delfile = "members/".$loggedin."/inventory/".$file1;
unlink($delfile);
}
if ($row['pic2'] == 0 ) {
echo "No Image 2";
} else {
$file2 = $row['pic2'];
$delfile2 = "members/".$loggedin."/inventory/".$file2;
unlink($delfile2);
}
if ($row['pic3'] == 0 ) {
echo "No Image 3";
} else {
$file3 = $row['pic3'];
$delfile3 = "members/".$loggedin."/inventory/".$file3;
unlink($delfile3);
}

 

Even though there is nothing in the database it is still trying to run the unlink for pic2 and pic3

 

Not sure what the problem is.

 

It will remove the image from 'pic'

You are checking to see if the database column is an integer value of zero

if ($row['pic2'] == 0 ) {

 

then you are using the value of the database column as a file name string

$file2 = $row['pic2'];

 

You should probably just test to see if the column is empty:

if (empty($row['pic2'](( {

What exactly is in the database? What does the following show when added inside of the while(){} loop -

 

echo '<pre>';
var_dump($row);
echo '</pre>';

Perfect, thanks DavidAM.

 

New Code that works:

 

$query = "SELECT  * FROM `cinvent` WHERE `oname`='$loggedin' and iid='$iid'";
$result = $mysqli->query($query) or die($mysqli->error.__LINE__);
while($row = $result->fetch_assoc()){

       if (empty($row['pic'])) {
       echo "No Image";
       } else {
        $file1 = $row['pic'];
        $delfile = "members/".$loggedin."/inventory/".$file1;
        unlink($delfile);
       }
       if (empty($row['pic2'])) {
       echo "No Image 2";
       } else {
        $file2 = $row['pic2'];
        $delfile2 = "members/".$loggedin."/inventory/".$file2;
        unlink($delfile2);
       }
       if (empty($row['pic3'])) {
       echo "No Image 3";
       } else {
        $file3 = $row['pic3'];
        $delfile3 = "members/".$loggedin."/inventory/".$file3;
        unlink($delfile3);
       }
}
