Question

I have my code written to select images from my database and display them, grouped by month. I would like every ‘month of photos’ to be in its own “container” div. I cannot figure out how to do this while in a WHILE LOOP. I think I need a way to tell if the next row of data, that is going to get iterated, is a new month or not. Any suggestions?

My code:

<?php

if (isset($_COOKIE['user_id']))
{
if (!isset($_GET['user_id']))
{
$user_id= $_COOKIE['user_id'];
}
else
{
$user_id= $_GET['user_id'];
}

$connect= mysqli_connect("localhost", "root", "", "si");
$query= "SELECT * FROM posts WHERE user_id= $user_id ORDER BY date DESC";

$result= mysqli_query($connect, $query)
or die('error with query');
$date = "0";

while ($row= mysqli_fetch_array($result)) {

if ($date != $row['date']) {
 echo "<p> ".$row['date']."</p><br/>";
 $date = $row['date'];
}

echo '<img src="'.$row['picture']. '"/>' . "<br/>";
}
}
?>

Here is how it should look…

For example, the FEB 2012 month should be in a different container div than JAN 2012.

It is quite easy to implement this at the same place where you create the month header.

$first = true;
if ($date != $row['date']) {
    if ($first) {
        $first = false;
    } else {
        echo "<\div>";
    }
    echo "<div><p> ".$row['date']."</p><br/>";
    $date = $row['date'];
}

Then you have to close the last div after the while loop by calling:

echo "</div>";
