Question

I am having issues with my JSON_encode and jQuery, I am getting it to post the full array with the following code, but I can’t get it to echo just the one array I need.

$.get("/indexget.php", { page: "goals" },function(data) {
$('#bodyContentStuff').text(data);

Full jQuery code

$("#navLinkGoals").click(function () {
    $("#bodyTitleBar").text("Goals");
    $.get("/indexget.php", { page: "goals" },function(data) {
        $('#bodyContentStuff').text(data);
    }
);

Full PHP code

if($_REQUEST['page'] = 'goals'){
    $result = mysql_query("SELECT * FROM content WHERE page='indexGoals'") 
    or die(mysql_error()); 
    $row = mysql_fetch_array( $result );
    $message = $row['message'];
}
echo json_encode(array("content"=>"$message"));

I am sort of a noob with programming, but the site is http://www.gronge.com if you’d like to see what it is doing, just click the goals link.

Edit: Oh, I have also tried

$('#bodyContentStuff').text(data['content']);

But it didn’t work.

Answer 1

Have you logged the data variable? What does it log? Also: mysql_* is deprecated, steer clear and start using PDO. But I think you meant to assign $row[0]['message'] to the $message variable. If memory serves me well, mysql_* always returns either an array of assoc arrays, or an array of arrays.

While we’re on the subject: JavaScript doesn’t have assoc arrays, only objects, so rather then accessing the data like data['content'], use data.content. The bracket notation is there for convenience, so you can use the value of a variable as property name (without eval), which is EVIL, of course.
