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

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 2

$temp_year = 0;
while($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 3

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>");
}

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>";
}
