in array sql query - php

Question

I have the following inside a foreach loop (displaying my various videos), I'm trying to display some alternate text for the top three voted videos. What on earth am I doing wrong (a lot clearly)...
$sql = "SELECT video_id FROM videos WHERE displayable='y' ORDER BY votes desc LIMIT 0,3";
$result = mysql_query($sql);
$row = #mysql_fetch_array($result);
if(in_array($video->getProperty('video_id')) == $row['video_id']) {
do this...
} else {
do this..
}

Answer 1

Firstly replace your code with some error preventing techniques like so!
$sql = "SELECT video_id FROM videos WHERE displayable='y' ORDER BY votes desc LIMIT 0,3";
if(false != ($result = mysql_query($sql))
{
$row = mysql_fetch_assoc($result); //Dont need the # restraint as the result is not false above.
//Also to get associate keys you need to use mysql_fetch_assoc
if($video->getProperty('video_id') == $row['video_id'])) //Remove the in array as your directly comparing the to entities with ==
{
//Match
}else
{
//Video does not match
}
}
Your main problem was the mysql_fetch_array(), Please research the differences with mysql_fetch_array() and mysql_fetch_assoc();

Edit: The way i would go
//Change the query and the loop way.
$sql = "SELECT video_id FROM videos WHERE displayable='y' AND video_id != '".(int)$video->getProperty('video_id')."' ORDER BY votes desc LIMIT 0,3";
if(false != ($result = mysql_query($sql))
//Use the # restraint if you have E_NOTICE on within E_Reporting
{
while($row = mysql_fetch_assoc($result))
{
//Print the $row here how you wish for it to be displayed
}
}else
{
//We have an error?
echo '<strong>Unable to list top rated videos, please check back later.</strong>'
}
}

mysql_fetch_array only returns a single row, you need to loop through your results to build an array containing the top three ids.
$sql = "SELECT video_id FROM videos WHERE displayable='y' ORDER BY votes desc LIMIT 0,3";
$result = mysql_query($sql);
while($row = #mysql_fetch_array($result)) {
$topthree[] = $row["video_id"];
}
Then you can use in_array but with the correct syntax:
if(in_array($video->getProperty('video_id'), $topthree)) {
do this...
} else {
do this..
}
