Question

This is the query part of my json.php which is the source file of my jquery ui autocomplete input

$term = trim(strip_tags($_GET['term']));//retrieve the search term that autocomplete sends

$qstring = "SELECT nombre as value FROM ingredientes WHERE nombre LIKE '%".$term."%'";
$result = mysql_query($qstring);//query the database for entries containing the term

while ($row = mysql_fetch_array($result,MYSQL_ASSOC))//loop through the retrieved values
{
    $row['value']=htmlentities(stripslashes($row['value']));
    //$row['id']=(int)$row['id'];
    $row_set[] = $row;//build an array
}
echo json_encode($row_set);//format the array into json data

The problem is that file my return result as:

[{"value":"one"},{"value":"one"},{"value":"ones"},{"value":"ona"}]

So the word will be suggested twice. How can I prevent that?

Answer 1

$qstring = "SELECT DISTINCT nombre as value 
    FROM ingredientes 
    WHERE nombre LIKE '%".$term."%'";

Or

$qstring = "SELECT nombre as value 
    FROM ingredientes 
    WHERE nombre LIKE '%".$term."%'
    GROUP BY nombre";

Do use mysql_real_escape_string though…
