Question

$myfile = mysql_query($query_myfile, $db) or die(mysql_error());
$totalRows_myfile = mysql_num_rows($myfile);
$typ_d = '';
$test='';


while ( $row_myfile = mysql_fetch_assoc($myfile) ) 
{
   if ( $typ_d != $row_myfile[ 'typ_d' ] ) 
   {

       $typ_d = $row_myfile[ 'typ_d' ];

       echo "<h2>$typ_d</h2>";

   }
   if ( $test != $row_myfile[ 'test' ] ) 
   {

       $test = $row_myfile[ 'test' ];

       echo "<h3>$test</h3>";
   }

   echo "<li><a href=\"myfileDetail.php?myfile_id=".$row_myfile['myfile_id']. "\">";
   echo $row_myfile['shortname'].' ';
   echo $row_myfile['name']; ?></a></li>

   <?php } ?>

This code list out element in group and subgroups like this

Typ_d (group) generated by

echo "<h2>$typ_d</h2>";

test(subgroup) generated by

echo "<h3>$test</h3>";

then the lists generated by

echo "<li><a href=\"myfileDetail.php?myfile_id=".$row_myfile['myfile_id']. "\">";
       echo $row_myfile['shortname'].' ';
       echo $row_myfile['name']; ?></a></li>

I have a problem generation the html tag as follow

<h2>Typ_d1</h2>
<h3> Test1</h3>
<ul>
  <li> List1</li>
  <li> List2 </li>
  <li>List3 </li>
</ul>
<h2>Typ_d2 </h2>
<h3>Test2</h3>
<ul>
  <li> List1</li>
  <li> List2</li>
  <li> List3</li>
</ul>
<h2> Typ_d3</h2>
<h3> Test3</h3>
<ul>
  <li> List1</li>
  <li> List2 </li>
  <li>List3 </li>
</ul>

I have tried so much but i cannot get it with the right order ..need help please

the current out put has not <ul> tag and I would like to put it in side the code

this is the current output

<li> List1</li>
  <li> List2 </li>
  <li>List3 </li>

<h2>Typ_d2 </h2>
<h3>Test2</h3>

  <li> List1</li>
  <li> List2</li>
  <li> List3</li>

<h2> Typ_d3</h2>
<h3> Test3</h3>

  <li> List1</li>
  <li> List2 </li>
  <li>List3 </li>

Ok, without doing a major restructuring of your code (e.g. into an MVC pattern), you’re better off compiling the data into an array first and then looping over that to generate the output, like @Blowski said. Something like this:

$myfile = mysql_query($query_myfile, $db) or die(mysql_error());


$groups = array();

while ( $row_myfile = mysql_fetch_assoc( $myfile ) ) {

  $typ_d = $row_myfile[ 'typ_d' ];

  $groups[ $typ_d ][ 'h2' ] = $row_myfile[ 'typ_d' ];

  $groups[ $typ_d ][ 'h3' ] = $row_myfile[ 'test' ];

  $groups[ $typ_d ][ 'files' ][] = <<<DOCHERE
<li>
<a href="myfileDetail.php?myfile_id="{$row_myfile[ 'myfile_id' ]}">{$row_myfile[ 'shortname' ]} {$row_myfile[ 'name' ]}</a>
</li>
DOCHERE;

}
// while


foreach ( $groups as &$group ) {

  $group[ 'files' ] = join( "\n\n", $group[ 'files' ] );

  $group = <<<DOCHERE
<h2>
{$group[ 'h2' ]}
</h2>

<h3>
{$group[ 'h3' ]}
</h3>

<ul>

{$group[ 'files' ]}

</ul>
DOCHERE;

}
// foreach


echo join( "\n\n\n", $groups );

Notes:

• You should almost certainly be html-escaping the variable values before outputting them in HTML.

• I’ve eliminated the ugly concatenation for HTML output generation and replaced it with variable interpolation.

• I’ve eliminated the ill-advised double-quoting of HTML output strings and used HEREDOCs instead.

• There are a lot of variations on details of how you could do this, e.g. call array_key_exists() in the while loop instead of just re-assigning the h2 and h3 keys each time, assign $groups[ $typ_d ] by reference to shorten the other assignment statements, etc.
