Use this method to override how string match is conducted. By default, the PHP Autocomplete matches searched term anywhere in options. In most case, you don’t need to call this method. Keep in mind that only a single matcher can be used.
Signature:
public function set_matcher($js_cust_matcher)
Parameters:
- $js_cust_matcher: JavaScript function to set custom matcher
Example that demos case sensitive search and must search from the beginning of the string
<?php
...
// only a single matcher can be used at a time
$pac->set_matcher('search_casesensitive_and_beginning');
...
?>
<script>
function search_casesensitive_and_startbeginning(term, text){
return (text.indexOf(term)>=0)
&&
text.toUpperCase().indexOf(term.toUpperCase())==0;
}
</script>
...
// only a single matcher can be used at a time
$pac->set_matcher('search_casesensitive_and_beginning');
...
?>
<script>
function search_casesensitive_and_startbeginning(term, text){
return (text.indexOf(term)>=0)
&&
text.toUpperCase().indexOf(term.toUpperCase())==0;
}
</script>
