I'm trying to echo out multiple rows from a sql database, but I get the error Warning. Illegal string offset 'Date' In....

$channel_check = mysql_query("SELECT content, Date FROM wgo WHERE Posted_By='$user' ORDER by `id` DESC;");
    $numrows_cc = mysql_num_rows($channel_check);
    if ($numrows_cc == 0) {
echo ''; 

// They don't have any channels so they need to create one?><h4> &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbspYou haven't posted anything yet.

Answer 1

DATE is a datatype in SQL, you need to escape it with back ticks

SELECT content, `Date` FROM wgo WHERE Posted_By='$user' ORDER by `id` DESC

Also, you're accessing your row incorrectly. Rows are typically represented by a uni-dimensional array, so $row['content'] and $row['Date']

Answer 2

$row is 1-dimensional array with 2 fields: content and Date .

Try,

while ($row = mysql_fetch_array($channel_check)) {
    print_r($row);
    //$channel_name = $row['content']['Date'];
