How to convert array to treeview in php
Below is my array
Array
(
[0] => Array
(
[efi] => Array
(
)
)
[1] => Array
(
[grub] => Array
(
[0] => Array
(
[fonts] => Array
(
)
)
[1] => Array
(
[i386-pc] => Array
(
)
)
[2] => Array
(
[locale] => Array
(
)
)
[3] => Array
(
[x86_64-efi] => Array
(
)
)
)
)
)
I want output as treeview
efi
grub
and under grub I want
fonts
i386-pc
locale
x86_64-efi
I have used below code for same
function generateTreeMenu($dir_array, $parent = 0, $limit=0){
if($limit > 1000) return '';
$tree = '';
$tree = '<ul>';
for($i=0, $ni=count($dir_array); $i < $ni; $i++){
if($dir_array[$i]['parent_id'] == $parent){
$tree .= '<li><a>';
$tree .= $dir_array[$i]['title'].'</a>';
$tree .= generatePageTree($dir_array, $dir_array[$i]['id'], $limit++);
$tree .= '</li>';
}
}
$tree .= '</ul>';
return $tree;
}
generateTreeMenu($dir_array);
it show warning Undefined property: stdClass::$parent_id in
Here is my solution, based on your post:
<?php
echo "<pre>";
$dir_array = array( array( "efi" => array() ),
array( "grub" => array(
array("fonts" => array()),
array("i386-pc" => array()),
array("locale" => array()),
array("x86_64-efi" => array())
)
)
);
print_r($dir_array);
echo "</pre>
";
function mygenerateTreeMenu($dir_array,$limit = 0)
{
$key = '';
if ($limit > 1000) return '';
foreach ($dir_array as $key => $value)
{
if (!is_int($key))
{
$tree .= "<li>";
$tree .= "<a>$key</a><ul>";
$tree .= mygenerateTreeMenu($value,$limit++);
$tree .= "</ul></li>
";
}
else
{
$tree .= mygenerateTreeMenu($value,$limit++);
}
}
return $tree;
}
echo "<ul>
";
$tree = mygenerateTreeMenu($dir_array);
echo $tree;
echo "</ul>
";
?>
I removed the $parent as I did not need it. Then because of the way your array is built, integer indexes are ignored. If you can modify your array, you could streamline it and remove integer indexes completely and treat is as a hash table. It would make the recursive code simpler.
