Em primeiro lugar, desculpe pelo meu pobre inglês.
Na sua consulta, em vez de fazer o pedido por id_location , faça ordenar pelo nome do componente . Dessa forma, você pode adicionar linhas dinâmicas facilmente. Não alterei seu programa de conexão, mas alterei sua segunda parte. Por favor, verifique. Eu sei que há 3 a 4 loops. Mas se algum corpo encontrou algo melhor, por favor me diga.
$sql1 = "SELECT * FROM Lokasi ORDER BY id_location";
$stmt1 = $dbc->prepare($sql1);
$stmt1->execute();
while ($row1 = $stmt1->fetch(PDO::FETCH_ASSOC)) {
$location++;
echo "Location $location : ".$row1['location'];
?>
<?php
$query = "SELECT *
FROM sub_component,
component
WHERE sub_component.id_component=component.id_component
AND component.id_location='$data[id_location]'
ORDER BY component.component_name";
$stmt = $dbc->prepare($query);
$stmt->execute();
# Declare two emty array
$component = array(); # Will store the components
$sub_component = array(); # Will store the sub components
$loop = 0;
# Now if any data is fetched from previsous query, then fill
# the above declared arrays.
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
$component[$loop] = $row['component'];
$sub_component[$loop] = $row['sub_component'];
$loop = $loop + 1;
}
# If no data fetched then I m telling
# No data fetched.
if (!sizeof($component)) {
echo 'Empty Data';
} else {
print "<table width='469px' border='1'>
<tr bgcolor='#00FFFF'>
<th width='109' class='rounded' scope='col'>Component</th>
<th width='109' class='rounded' scope='col'>Sub Component</th>
</tr>";
# Now our main logic starts to print dynamic rowspan
# Go for a loop.
# Here the imporant is to use for loop
$tmp_arr = array();
$main_assoc_arr = array();
for ($i = 0; $i < sizeof($sub_component); $i++) {
array_push($tmp_arr, $sub_component[$i]);
# If we have reached the last element
# and in $main_assoc_arr the comonent is not exist
# Then we will store them as following.
if ( $i = (sizeof($sub_component)-1)
&& !array_key_exists($component[$i], $main_assoc_arr)) {
$main_assoc_arr[ $component[$i] ] = array();
$main_assoc_arr[ $component[$i] ] = $tmp_arr;
# Restore the array.
$tmp_arr = array();
# Also get out of the loop
break;
}
# If the present component is not equal to the
# Next component then
if ($component[$i] != $component[$i+1]) {
$main_assoc_arr[ $component[$i] ] = array();
$main_assoc_arr[ $component[$i] ] = $tmp_arr;
# Restore the array.
$tmp_arr = array();
}
}
# Now we are going to print the table with rowspan.
foreach ($main_assoc_arr as $comp=>$sub_comp) {
$printed = 0;
$rowspan = sizeof($sub_comp);
foreach ($sub_comp as $elm) {
print "<tr>";
# Manke sure that the column will not print
# in each loop as it conatins dynamic array.
if (!$printed) {
print "<td rowspan='$rowspan'>$comp</td>";
}
print "<td>$elm</td>"
print "</tr>";
}
}
print "</table>";
}
?>
