Search result without duplicates

Nico3939 · 2017-07-25 18:43:23

Hi,

I have some photos that are present in several albums. Is it possible during a search, to tell Backlight not to display duplicates?

Thanks
Nico

The search doesn't filter for duplicates. It simply checks for hits in each albums and displays the results.

Ah OK, I thought there would be a way to tweak a code of the following style:

$sql = "SELECT distinct filename from my_table";
$res = mysql_query($sql);

while($row = mysql_fetch_array($res))
{
    echo $row['filename'].'<br /><br />';
}

Thanks
Nico

This is something we could add via a Publisher setting (e.g. Remove Duplicate Photos in Search). I've added it to our feature list for possible future updates.

I've added this into the next major version of Backlight.

Whaoo! Very cool ! Thanks very much Ben!!!

No worries. Emphasis on next *major* version, which will be a paid upgrade.

If you feel inclined to edit Backlight, the same result can be achieved by editing the file backlight/publisher/application/models/SearchResult.php, changing this:

	function getFilteredPhotoResults()
	{
		$filtered = array();
		
		foreach ($this->photoResults as $photo) {
			if ($photo->filter($this->required, $this->omitted)) {
				$filtered[] = $photo;
			}
		}

		return $filtered;
	}

To this:

	function getFilteredPhotoResults() 
	{
		$filenameLookup = array();
		$removeDuplicates = true;

		$filtered = array();
		
		foreach ($this->photoResults as $photo) {
			if ($removeDuplicates) {
				if (isset($filenameLookup[$photo->getFilename()])) {
					continue;
				} else {
					$filenameLookup[$photo->getFilename()] = true;
				}
			}

			if ($photo->filter($this->required, $this->omitted)) {
				$filtered[] = $photo;
			}
		}

		return $filtered;
	}

This functionality will be configurable in the next major version of Backlight.

Hi,

I just try the code but I have the following error:

"Something went wrong

Unexpected error: syntax error, unexpected '$filtered' (T_VARIABLE) in SearchResult.php on line 182

Please report error at http://community.theturninggate.net"

what’s on line 182?
Chances are the syntax error is near that.

You may not have copied all the code Ben posted. Or perhaps you opened the file indicated in a word processor and inherited its formatting?

Make sure you’re replacing code and not just adding the modified code.

Ok I find the problem.

In your code there is a punctuation symbol (;) forgotten at the end of the next line:

$removeDuplicates = true

Replace by:

$removeDuplicates = true;

and it work

Thanks very much
Nico
