I have created 2 autosuggest textboxes in which one is fetching data from server-side and another is fetching data from client-side.But server-side textbox is not working.Can anyone point out the error in my code.
Following is my HTML Code:
<html>
<link type="text/css" rel="stylesheet" media="all" href="jquery-ui-1.8.9.custom.css" />
<script type="text/javascript" src="jquery-1.4.4.min.js"></script>

<script type="text/javascript" src="languages.js"></script>
<body>
<label for="languagesClientInput">Select Language(client-side): </label>
<input id="languagesClientInput" />
<br />
<label for="languagesServerInput">Select Language (server-side): </label>
<input id="languagesServerInput" />
</body>
</html>
Following is Js Code:
$(function() {
var languages = [
"C",
"C++",

"Advance Java",
"PHP",

];
$("#languagesClientInput").autocomplete( { source: languages });
$("#languagesServerInput").autocomplete( { source: "languages.php" });
});
Following is Php Code:
<?php
$searchTerm = $_GET['term'];
$languages = array(
"C",
"C++",
"Core Java",
"Advance Java",
"PHP",
".NET",
"XML",
"HTML",

);
function filter($language) {
global $searchTerm;
return stripos($language, $searchTerm) !== false;
}
print(json_encode(array_values(array_filter($languages, "filter"))));
?>
The array_filter function fails. If you remove it you will get the data you need.
I actually think you have made a mistake there by writing array_filter instead of just filter to call the function you wrote above.

Download jquery.min.js and rename it to jquery.js
Now open index.php in your localhost/server and test it. Follow the similar method with your wordlist.
You don't need the array_values function. This worked for me:
// languages.php
<?php
function filter($language) {
global $searchTerm;
return stripos( $language, $searchTerm ) !== false;
}
$searchTerm = $_GET['term'];
$languages = array(

I'm using the FoxyComplete plugin with Jquery Auto-Complete to do a simple search. Everything is setup and working great but I'm finding the search results extremely limiting.
I use a big JSON file for all of my data and the problem I'm having is in the following case: Let's assume that my JSON file has the following description:
{
"title": "Brand new black car"
},
If a user searches "black car", he or she will get the result perfectly and the search is great. BUT, if a user search "car new", nothing comes up even though both keywords are in my JSON file.
Any help would be great. I poured through the Jquery AutoComplete docs and couldn't find a solution either. My Jquery autocomplete js is below:

delay: isUrl ? $.Autocompleter.defaults.delay : 10,
max: options && !options.scroll ? 10 : 150
}, options);
// if highlight is set to false, replace it with a do-nothing function
options.highlight = options.highlight || function (value) {
return value;
};
// if the formatMatch option is not specified, then use formatItem for backwards compatibility
options.formatMatch = options.formatMatch || options.formatItem;
