[SOLVED] search tag highlighter

[DeanWhitehouse]

At the moment i am using this code to replace any words with highlighted ones that are searched for, but at the moment this will change the words to the one that was searched (normally in lower case). How can i have it keep the original word.

 

e.g

searched the word: "test"

it will show the tag as "test" even if it is saved as "TeSt"

 

<?php
			$tags = $rows['tags'];	
			$tags = str_replace(","," ",$tags);
			$tags = str_ireplace($search,"<b style=\"color:#0000FF;\">".$search."</b>",$tags);	

			$title = ucfirst($rows['title']);
			$title = str_ireplace($search,"<b style=\"color:#0000FF;\">".$search."</b>",$title);

?>

 

This doesn't make much sense, but hopefully you understand

Not sure if this would work but:

 

<?php
preg_replace("/" . $search . "/i", "<b style=\"color:#0000FF;\">$1</b>",$title);
?>

 

Not 100% sure but looking into the preg_replace you can actually call what was found using the $1 etc.

Using

$tags = preg_replace("/" . $search . "/", "<b style=\"color:#0000FF;\">$1</b>",$tags);

This doesn't do anything, it just shows the tag normally

Also how can i remove duplicate words from an array. i have tried

<?php
$tags = make_safe($_POST['tags']);
$tag = explode(",",$tags);
foreach($tag as $t)
{
	if(substr_count(strtolower($tags),strtolower($t)) > 1)
	{
		$dup[] = $t;
	}	
}

foreach($dup as $dupilcate)
{
	if(substr_count(strtolower($tags),strtolower($dupilcate)) > 1)
	{
		//echo $t."<Br>";
		$pos = stripos($tags,$dupilcate);
		$len = strlen($dupilcate);
		$ta = substr_replace($tags,"",$pos,$len);
	}	
}
print_r($ta);
?>

[DeanWhitehouse]

Haha

<?php
$tags = make_safe($_POST['tags']);
$tags = explode(",",$tags);
$tags = array_unique($tags);
$tags = implode(",",$tags);
echo $tags;
?>

Nice, glad you got it working and posted the example =) I guess I mis-understood the question, I was under the impression that you were parsing text in like a blog or essay form and highlighting that....

That code i just posted was removing duplicate tags, i still haven't got

$tags = preg_replace("/" . $search . "/", "<b style=\"color:#0000FF;\">$1</b>",$tags);

working

And here is the page using it
