Triggering action from a select using jquery and php

Question

i'm having a problem with jquery and php, mainly php :S i have a select populated via php, that's the code:

<script type="text/javascript" src="js/jquery.min.js"></script>
<script type="text/javascript" src="js/script.js"></script>
<select name="gname" id="gnome">
<option>Scegli...</option>
<?php 
include ('php/config.php');
//recupero organizzazioni dal database
$sql = "SELECT DISTINCT gname, count(*) as number
        FROM gtdb
        WHERE `country` = 4 OR `country` = 103 OR `country` = 107 OR `country` = 219 OR `country` = 210 OR `country` = 210 OR `country` = 153 OR `country` = 110 OR `country` = 200 OR `country` = 102 OR `country` = 95 OR `country` = 173 OR `country` = 228 OR `country` = 152 OR `country` = 97 OR `country` = 94 
        GROUP BY gname
        HAVING number >= 20
        ORDER BY gname";
$result = mysql_query($sql, $mysql);
while($nome = mysql_fetch_array($result)) {  
?>

<option value= "<?php echo $nome['gname'];?>" ><?php echo $nome['gname']; ?></option>
<?php  
    };   
?> </select>

when i select an option, this jQuery function should post the value of the option to a php script and append the result into a "result" div. jquery code:

$(document).ready(function() {
    $('#gnome').change(function() {
        var inpval=$(this).val();
        $.ajax({
            url: 'php/query.php',
            type: 'POST',
            data: {valor : inpval},
            success: function(data) {
                $('.result').html(data);
            }
        });
    });
});

PHP code:

<?php 
    include('config.php'); //database connection(works)

    $org_name=$_POST['valor']; 
    $query=mysql_query("SELECT * FROM gtdb WHERE gname LIKE '$org_name%'");
    while($row=mysql_fetch_assoc($query)){
        $row['name'];
    }
?>

Actually i'm able to connect to the database, do a query and populate the select, but when i select an option nothing happens, i don't know if it's fault of the jquery code or of the php code, any help? Thanks in advance :)

Answer 1

Please change:

data: ({valor : inpval}),

To:

data: {valor : inpval},

And the statement obtaining the data value should be:

var inpval = this.value;

JS FIDDLE DEMO

When you change the select value please open dev tools and check the network tab and you'll see that the ajax call is made.

Also make sure you have an element with the class result is on the page.

NOTE: Your PHP script needs to be edited so it can return something, maybe echo $row['gname'];
