SQL Question

Autocomplete doesnt work - PHP - Mysql - jQuery

When I type anything in the text box it doesn't display anything.
The search.php shows all the records if I hardcode

$searchTerm='a';


Probably it is something in the jQuery I am missing.

<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>test</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<script>
$(function() {
$( "#skills" ).autocomplete({
source: 'search.php'
});
});
</script>
</head>
<body>

<div class="ui-widget">
<label for="skills">skills: </label>
<input id="skills">
</div>
</body>
</html>


MY PHP (search.php) page is:

//get search term
$searchTerm = $_GET['term'];

//get matched data from skills table
$query = $db->query("SELECT * FROM skills WHERE skill LIKE '%".$searchTerm."%' ORDER BY skill ASC");
while ($row = $query->fetch_assoc()) {
$data[] = $row['skill'];
}

//return json data
echo json_encode($data);


Json

["A A EDU","A T Still","A.B.I. ","Aani", "Zane"]

I can´t see the send params (data) to you server call.

like this (but i haven´t right if this work):

$(function() {
   $( "#skills" ).autocomplete({
      source: 'search.php',
      data: { 
         'term' : $('#skills').val()
      },
      type: "GET"
   });
});

I prefer use a plugin to do this, in the method AJAX is possible set the results to list in field. like this:

$('#field_auto_complete').autocomplete({
    lookup: function (query, done) {
        $.ajax({
            url: "form.php",
            dataType: "json",
            data: { 
                    term     : query 
            },
            type: "GET", //you can change to POST if u need
            success: function( response ){
                var result = {
                    suggestions: response.results
                };
                done(result);   
            },
            error: function(XMLHttpRequest, textStatus, errorThrown) { 
                $.redirect('../error');
            }
        });
    },
    onSelect: function (suggestion) {
        id_ofselected = suggestion.data; //set a var with selected object
    }
});

In the Php Side u have a code like this:

$digits = $_GET['term'];

$query = $db->query(SELECT name AS `value`, id AS `data` 
          FROM table 
          WHERE name LIKE '$digits%'");

while ($row = $query->fetch_assoc()) {
    $data[] = $row['skill'];
}

if(isset($data[0])){
    echo json_encode(array( 'results' => $cons ));
}else{
    echo json_encode(array( 'results' => array());  
}

I use Autocomplete Jquery plugin. See [a link] (https://github.com/devbridge/jQuery-Autocomplete)!
