<script src="http://code.jquery.com/jquery-1.5.min.js"></script>
<script>
$(document).ready(function () {
var $article = null;
$('#category').change(function () {
var $categoryName = $("#category").attr('value');
if ($article == null) {
$article = $('<h4>Select a business you wish to view.</h4><select id="business" name="business" class="business"></select>').appendTo('.query');
$("#business").load("php.php", {categoryName:$categoryName});
}
});
});
</script>
category is the id/class/name given to my select box, Each option is populated through php and is given a value="$row['colName']", I am trying to pass that selected value to a php document on change. So I can pass that value to the next queries WHERE clause.
Can you help me correct the
var $categoryName = $("#category").attr('value');
line to get the selected index of #category and the value for w.e option is selected?
here is php.php
<?php
$con = mysqli_connect(,,,,);
// Check connection
$myVar = $_GET["categoryName"];
if (mysqli_connect_errno())
{
echo "<option>Failed to connect to the Database</option>" ;
}
echo "<option>Select A Business To View Listing</option>";
$result = mysqli_query($con,"SELECT BName, Category FROM Business WHERE Category=$myVar");
while($row = mysqli_fetch_array($result)) {
echo "<option class='".$row['BName']."'>".$row['BName']."</option>";
}
// Free result set
mysqli_free_result($result);
mysqli_close($con);
?>

var $categoryName = $(this).val();
This is the correct way to get the current value of an input element with jQuery.
