Question

I’ve spent hours trying to make this work. No solutions from the search have helped me, so I’m finally asking.

What I’m trying to do is: Display a message if no results are found.

This is what I have, and it is currently not working to my dismay.

    $sql = mysql_query("SELECT * FROM cover WHERE MATCH(keyword,description,categories) AGAINST('$search_key' in boolean mode) ORDER BY id DESC LIMIT $from , $perPage");

    $i=1;
    while($result = mysql_fetch_object($sql)) {

    $keyword = $result->keyword;
    $img = $result->img;
    $description = $result->description;

    if($img != null) { DO THIS;
    if($i==2) { require_once(dirname(__FILE__).'/page.php'); }
    $i++; }
    }
    if($img == null) { print "<center>No Results Found</center>"; }

I don’t know how to use mysql_num_rows with this (which is what I’ve seen is the most popular solution around the site), it returns an error and I’m thinking it doesn’t work well with mysql_fetch_object($sql) ? And I don’t think this: $img = $result->img; would work with mysql_num_rows either.

I’m just trying to find a way to do this without having to modify anything inside the brackets, just the ones outside.

When I say “NOT WORKING”, I mean it doesn’t show the message that is supposed to show if results are not found. I’ve tested if($img != null) { print "<center>No Results Found</center>"; } and it works fine, it shows the message. But it doesn’t seem to work the other way, and I’m now just confused.

Answer 1

The following will work:

$sql = mysql_query("SELECT * FROM cover WHERE MATCH(keyword,description,categories) AGAINST('$search_key' in boolean mode) ORDER BY id DESC LIMIT $from , $perPage");
if(mysql_num_rows($sql) > 0)
{
    $i=1;
    while($result = mysql_fetch_object($sql)) 
    {
        $keyword = $result->keyword;
        $img = $result->img;
        $description = $result->description;

        if($img != null) 
        { 
            DO THIS;
            if($i==2) 
            { 
                require_once(dirname(__FILE__).'/page.php'); 
            }
            $i++; 
        }
    }
}
else
{ 
    print "<center>No Results Found</center>"; 
}

I see no reason why you would want to store the values from $result into separate variables when you can simply use the $result->keyword directly.
