[RESOLVED] Selecting an image...

kiwis

I have this script (which is longer) to associate a image to a news title, this works but has no order or preferance as such.

if (preg_match("/TeamName/i", "$title")) {
$img = "tt.jpg";
} else if (preg_match("/PlayerName/i", "$title")) {
$img = "jj.jpg";
} else if (preg_match("/AnotherWord/i", "$title")) {
$img = "gg.jpg";
} else if (preg_match("/AnotherTeamName/i", "$title")) {
$img = "hh..jpg";
} else if (preg_match("/GroundName/i", "$title")) {
$img = "tans.jpg";
} else if (preg_match("/uk/i", "$title")) {
$img = "uk.jpg";


} else {
$img = "image1.jpg";
}

What I mean is that if the title was "TeamName wins at GroundName" or "TeamName beats AnotherTeamName" then you are always going to show the name of the secord requirement.

How else could I do this to show a better variety of images, a lot of my articles include "TeamName" so i see the tt.jpg image a lot.

I would use something like this:

$list_of_possible_images = array();
if (preg_match("/TeamName/i", "$title")) { $list_of_possible_images[] =  "tt.jpg"; }
if (preg_match("/PlayerName/i", "$title")) { $list_of_possible_images[] = "jj.jpg"; }
if (preg_match("/AnotherWord/i", "$title")) { $list_of_possible_images[] =  "gg.jpg"; }
if (preg_match("/AnotherTeamName/i", "$title")) { $list_of_possible_images[] =  "hh..jpg"; }
if (preg_match("/GroundName/i", "$title")) { $list_of_possible_images[] =  "tans.jpg"; }
if (preg_match("/uk/i", "$title")) { $list_of_possible_images[] =  "uk.jpg"; }
if (!count($list_of_possible_images)) { $list_of_possible_images[] = "image1.jpg"; } 
$img = $list_of_possible_images[rand(0,count($list_of_possible_images)-1)];

So I was a bit bored.

$title = "This string mentions the TeamName and AnotherTeamName and also mentions the GroundName while earning a rebuke.";

$patterns = array(
'TeamName'=>'tt.jpg',
'PlayerName'=>'jj.jpg',
'AnotherWord'=>'gg.jpg',
'AnotherTeamName'=>'hh.jpg',
'GroundName'=>'tans.jpg',
'uk'=>'uk.jpg',
//....
);

$pattern = "/".join('|', array_keys($patterns))."/i";
if(preg_match_all($pattern, $title, $matches))
{
	$list_of_possible_images = array_intersect_key($patterns, array_flip($matches[0]));
	$img = $list_of_possible_images[array_rand($list_of_possible_images)];
}
else
{
	$img = 'image1.jpg';
}

I get this error

Fatal error: Cannot use [] for reading in /home/mysite/public_html/modules/top.php on line 47

Line 47 being

if (!count($list_of_possible_images)) { $list_of_possible_images[] = "image1.jpg";
