Hi, so, I'm trying to loop through all my blog posts and display them to the page in order so the newest entry is first but I can't seem to get it too work. tried a few different ways and always white screen! Any help would really be appreciated :). I'm also going to add a search function and filters, I don't need this now but any suggestions where to look to find info about implementing these would also be really helpful. Link to where I'm putting this code on my website: http://www.obeytoplay.com/ . Thanks!

tried a few different ways and always white screen!

That's because there's a syntax error in your code. Either escape the inner double quotes( " ) using backslash( \\ ) or use single quotes( ' ).

Method(1):

include "connection file";
$query = "SELECT * FROM Blog";
$result = mysqli_query($query);
$num_results = mysqli_num_rows($result);
for($i=0; $i<$num_results; $i++) {
    $row = mysqli_fetch_assoc($result);
    echo "<div class=\"blogEntry\"><h4>" . $row['title'] . "</h4><h5>" . $row['date'] . "</h5><p>" . $row['text'] . "</p></div>";
}  

Method(2):

include "connection file";
$query = "SELECT * FROM Blog";
$result = mysqli_query($query);
$num_results = mysqli_num_rows($result);
for($i=0; $i<$num_results; $i++) {
    $row = mysqli_fetch_assoc($result);
    echo "<div class='blogEntry'><h4>" . $row['title'] . "</h4><h5>" . $row['date'] . "</h5><p>" . $row['text'] . "</p></div>";
}

Use ORDER BY in conjunction with SELECT clause to reorder the result set, like this:

SELECT * FROM Blog ORDER BY column_name DESC/ASC;

Here's the reference:
