Hi,
I'm having a problem with the following function:
function terms($term,$field){
if(strlen($term)>0){
if(!stristr($term, $field) === FALSE) {
$output = str_replace($term, "<b>".$term."</b>", $field);
} elseif(!stristr(strtolower($term), $field) === FALSE) {
$output = str_replace(strtolower($term),
"<b>".strtolower($term)."</b>", $field);
} elseif(!stristr(strtoupper($term), $field) === FALSE) {
$output = str_replace(strtoupper($term),
"<b>".strtoupper($term)."</b>", $field);
} elseif(!stristr(ucfirst($term), $field) === FALSE) {
$output = str_replace(ucfirst($term),
"<b>".ucfirst($term)."</b>",
$field);
}
} else {
$output = $field;
}
return $output;
}
I'm not comfortable enough with regex etc, so tried it my way, but no joy.
For info, I am trying to highlight search terms in results.
Any suggestions?
George
