Archive by year and month - php

Question

I'm trying to build a year\month archive.
It refuses to output what i want so i'm hoping one of you might push me in the right direction.
I want to sort by year, and show the months for each year ( if exists) and output it like this:
2012
- June
- August
2011
- July
my code is this :
$query = "SELECT * FROM article WHERE full_name ='$safe_name' group by year, month";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
$year = $row['year'];
$month = $row['month'];
echo "<ul class='year'><li><a>{$year}</a>";
echo "<ul class='months'><li><a>{$month}</a></li></ul>
</li></ul>";
}
But it outputs :
2012
- june
2012
- august
2011
- july
When i group only by year, it will output:
2012
- june
2011
- july
i have a "date_posted" row which is datetime (yyyy-mm-dd 00:00:00).
On top of that i have 1 row for month and 1 for year ( i know that's dumb, but i couldnt figure out how to do this by just using the "date_posted" row.
Ive read up on some posts on this topic, but its not doing the trick for me.
Any help is greatly appreciated!

Answer 1

This should work. When fetching results, sometimes it's handy to restructure it to be easily usable in iterating a view.
$query = "SELECT * FROM article WHERE full_name ='$safe_name' group by year, month";
$result = mysql_query($query) or die(mysql_error());
while($row = mysql_fetch_assoc($result)) {
// Get data
$year = $row['year'];
$month = $row['month']
// Structure it
$archive[$year][] = $month;
}
// Display data
foreach($archive as $year => $months)
{
// Show year
echo "<ul class='year'><li><a>{$year}</a>";
// Month container
echo "<ul class='months'>"
// Get months
foreach($months as $month)
{
echo("<li><a>{$month}</a></li>";
}
// Close Month/Year containers
echo("</ul></li></ul>");
}

You need to use a simple 'state' machine to detect when a year changes:
$previous_year = null;
$frist = true;
echo "<ul>"
while($row = mysql_fetch_assoc($result)) {
if ($row['year'] != $previous_year) {
// got a new year
if (!$frist) {
echo "</ul></li>"; // only close a previous list if there IS a previous list
$frist = false;
}
echo "<li class="year">$row[year]\n<ul>";
$previous_year = $row['year'];
}
echo "<li class="month">$row['month']</li>";
}

Answer 3

$temp_year = 0;
while($row = mysql_fetch_assoc($result)) {
$year = $row['year'];
$month = $row['month'];
if( $temp_year != $year )
{
if( $temp_year > 0 )
echo "</li></ul>";
$temp_year = $year;
echo "<ul class='year'><li><a>{$year}</a>";
}
echo "<ul class='months'><li><a>{$month}</a></li></ul>";
}

Answer 4

Give a shot
$storage_array = array();
while($row = mysql_fetch_assoc($result)) {
$year = $row['year'];
$month = $row['month'];
$storage_array[$year][] = $month;
}
foreach ($storage_array as $year => $month_array){
echo "<ul class='year'><li><a>{$year}</a>";
foreach ($month_array as $month){
echo "<ul class='months'><li><a>{$month}</a></li></ul>";
}
echo "</li></ul>";
}
