[RESOLVED] Help needed with Querying and Printing one of same named item

[tuxandpucks]

Hi

I am trying to figure out how to print one of same-named pieces of software from my database. I'll explain further.

I have a list of software to show people what has been recently updated.

For example in my database I have the following columns.

id, name, version, link, description, dateadded, category

and this is my code to query and print the records:

    $query=("SELECT * FROM software ORDER BY name ASC");
    $result=mysql_query($query) or die('Sorry, could not get software at this time '.mysql_error());
        while($row=mysql_fetch_array($result))  {

            $id=$row['id'];
            $name=$row['name'];
            $version=$row['version'];
            $link=$row['link'];
            $description=$row['description'];
            $dateadded=$row['dateadded'];
            $category=$row['category'];

echo "<div id=\"softwaredistro_page_main\">";
echo "$name" . "&nbsp<a href=\"singlesoftwarepiece.inc.php?id=$id&name=$name&version=$version&url=$link&description=$description&category=$category\"/>go</a>" . "<br>";
} 

This code works well to print out my records. Now here is the problem. I have some pieces of software that have been updated and entered into my database a two or three times so I end up with:

(For example):

Calibre
Evolution
Evolution
Opera Web Browser
Opera Web Browser
And so on...

How do I query, if it is done in the query, obtain only the most recently updated version of a piece of software so I end up with:

Calibre
Evolution
Opera Web Browser
And so on...

I want to keep all versions, so deleting an old one is not something I want o do.

And, lastly, I did try to use LIMIT clause in my query with no success. Otherwise, I am just stumped.

Thanks in advance,
Randy

Use a temporary variable to check is the $name already is used

$query=("SELECT * FROM software ORDER BY name ASC, version DESC");
    $result=mysql_query($query) or die('Sorry, could not get software at this time '.mysql_error());
        while($row=mysql_fetch_array($result))  {

            $id=$row['id'];
            $name=$row['name'];
            $version=$row['version'];
            $link=$row['link'];
            $description=$row['description'];
            $dateadded=$row['dateadded'];
            $category=$row['category'];

            if (!isset($temp[$name])) {

echo "<div id=\"softwaredistro_page_main\">";
echo "$name" . "&nbsp<a href=\"singlesoftwarepiece.inc.php?id=$id&name=$name&version=$version&url=$link&description=$description&category=$category\"/>go</a>" . "<br>"; }

            $temp[$name]=1;

}
