Ik probeer een auto complete in mijn script te bouwen zodat bij het typen gebruikers snel kunnen worden gevonden
Deze gebruikers laad ik uit de tabel users en wil ze selecteren op login. Echter krijg ik het niet voor elkaar om de autocomplete ook daadwerkelijk te laten werken.
Iemand enig idee hoe ik dit kan oplossen?
<?php
// PHP5 Implementation - uses MySQLi.
// mysqli('localhost', 'yourUsername', 'yourPassword', 'yourDatabase');
$db = new mysqli('localhost', 'root' ,'root', 'naamdb');
if(!$db) {
// Show error if we cannot connect.
echo 'ERROR: Could not connect to the database.';
} else {
// Is there a posted query string?
if(isset($_POST['queryString'])) {
$queryString = $db->real_escape_string($_POST['queryString']);
// Is the string length greater than 0?
if(strlen($queryString) >0) {
// Run the query: We use LIKE '$queryString%'
// The percentage sign is a wild-card, in my example of countries it works like this...
// $queryString = 'Uni';
// Returned data = 'United States, United Kindom';
// YOU NEED TO ALTER THE QUERY TO MATCH YOUR DATABASE.
// eg: SELECT yourColumnName FROM yourTable WHERE yourColumnName LIKE '$queryString%' LIMIT 10
$query = $db->query("SELECT login FROM users LIKE '$queryString%' LIMIT 10");
if($query) {
// While there are results loop through them - fetching an Object (i like PHP5 btw!).
while ($result = $query ->fetch_object()) {
// Format the results, im using <li> for the list, you can change it.
// The onClick function fills the textbox with the result.
// YOU MUST CHANGE: $result->value to $result->your_colum
echo '<li onClick="fill(\''.$result->value.'\');">'.$result->value.'</li>';
}
} else {
echo 'ERROR: There was a problem with the query.';
}
} else {
// Dont do anything.
} // There is a queryString.
} else {
echo 'There should be no direct access to this script!';
}
}
?>

En in mijn scripts laad ik de tekst via
<div>
<form>
<div>
Ding:
<br />
<input type="text" size="30" value="" id="inputString" onkeyup="lookup(this.value);" onblur="fill();" />
</div>
<div class="suggestionsBox" id="suggestions" style="display: none;">
<img src="upArrow.png" style="position: relative; top: -12px; left: 30px;" alt="upArrow" />
<div class="suggestionList" id="autoSuggestionsList">
</div>
</div>
</form>
