Using jQuery and php to pull data from database - php

Question

I have a page that is pulling data through jQuery but it is only pulling the return code. Here is my code:
<script type='text/javascript' language='javascript'>
function showCU() {
$.post('getCU.php', {
cuid: $('#cuContact').val()
},
function (response) {
$('#contact').val(response).show();
$('#email').val(response).show();
$('#phone').val(response).show();
})
}
</script>
$select = "SELECT priContact, priEmail, priPhone FROM user WHERE id = '" . $_POST['id'] . "'";
$query = mysql_query($select) or die ("Could not get info: " . mysql_error());
if (mysql_num_rows($query) > 0) {
while ($get = mysql_fetch_array($query)) {
$priContact = $get['priContact'];
echo $priContact;
echo $get['priEmail'] . " | " . $get['priPhone'];
}
} else {
echo "No users";
}
So the call is pulling from getCU.php whenever the onchange event handler is called. That is why this is in a function. What I want to do is every time a user chooses something from the option list the text values change according to what was selected. I have the php page pulling from a db and echoing out the code correctly. jQuery id pulling the data from the php page correctly, but I cannot get the code to place the single details in each of the text boxes.
So what I want to happen is this:
A user selects a name from a drop-down box. Then the mysql data attached to that name would be displayed on the page in form text fields.
Let me know if more information or code is needed.

I think you'll be better off structuring your data. My general recommendation is JSON.
// QUICK WARNING: Don't take unparse GET/POST responses.
// This is asking for trouble from SQL injection.
$select = "SELECT priContact, priEmail, priPhone FROM user WHERE id = '" . mysql_escape_string($_POST['id']) . "'";
$query = mysql_query($select) or die ("Could not get info: " . mysql_error());
$retVal = array();
if (mysql_num_rows($query) > 0) {
$retVal['data'] = array();
while ($get = mysql_fetch_array($query))
{
$retVal['data'][] = $get;
}
} else {
$retVal['error'] = 'No users';
}
header('Content-type: application/json');
echo json_encode($retVal);
Javascript:
<script type="text/javascript">
function showCU() {
$.post('getCU.php', {
cuid: $('#cuContact').val(),
dataType:'json'
},
function (response) {
if (response.error) {
//handle error
}
else
{
$('#contact').val(response.data.priContact).show();
$('#email').val(response.data.priEmail).show();
$('#phone').val(response.data.priPhone).show();
}
})
}
</script>
