found search text - highlight and crop the result

found search text - highlight and crop the result

I do a full text search in a mysql database field. The result works as expected, but I need 2 more things on the result page:
1) I want to show only part of the text found. It should serve as a link.
2) I want to emphasize the search word within this text part.

Is there a function somewhere which does the job similar to Tom Mucks

Dynamic Search Extension Suite for PHP in extensions/ ?

any idea?
thanks

Interesting question, this is something I would like to see incorporated into DataAssist Search as well.

1) to show only a part of a string, use the substr() function.

the substr() function takes 3 arguments:
the string
starting character
ending character

to show the first 11 characters of a string use:
<?php echo substr($row_RSName['ColumnName'], 0, 12); ?>

2) I will add a feature request for adding search string highlighting to DataAssist search. For now though, you would need to hand code this. I was able to find a number of examples of how to accomplish this using javascript through google:

search?q=javascript+highlight+search+text&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a

Jason,

the only issue I have with your suggestion is that personally I would want the search term to appear in the text displayed with a set number of words either side of it and what you suggest doesn't guarantee it.

That would be a much more complex bit of code.


you could explode the string into an array, then loop through the array to find the search phrase then show it along with the word before or after. A very quick sample of the code for that would look like:

php:
<?php 

$searchPhrase 
"this is some stuff on my page, I hope you like it";
$searchTerm "stuff";
$searchIndex "";
$searchArray explode(" "$searchPhrase);
foreach(
$searchArray as $key  => $value) {
    if(
$value == $searchTerm$searchIndex $key;
}
echo(
$searchArray[$searchIndex-1]." <span style=\"color:red;\">".$searchArray[$searchIndex]."</span> ".$searchArray[$searchIndex+1]);
?>





of course, there are a number of scenarios this code does not account for, what if the search phrase is the first word? last word? it is meant as an example of one direction you could go.

I know :-)

Thanks for the ideas at some point in the near future I'll look at this in more detail.
