I'm using drupal's NAT module and need to get the nid from the term id.
Here's what I tried:
foreach ( (array)nat_get_nids($termid) as $natid ) {
$NatName = $natid->name;
}
print $natid;
This does not work.
Node auto term's get nid function is like this:
function nat_get_nids($tids, $get_nodes = FALSE) {
static $nid_cache = NULL;
static $node_cache = NULL;
$return = array();
// Keep processing to a minimum for empty tid arrays.
if (!empty($tids)) {
// Sort tid array to ensure that the cache_string never suffers from order
// issues.
sort($tids);
$cache_string = implode('+', $tids);
if ($get_nodes) {
if (isset($node_cache[$cache_string])) {
return $node_cache[$cache_string];
}
elseif (isset($nid_cache[$cache_string])) {
// If the nid cache stores the same string, node_load() each nid and
// return them.
$return = array();
foreach (array_keys($nid_cache[$cache_string]) as $nid) {
$return[$nid] = node_load($nid);
}
$node_cache[$cache_string] = $return;
return $return;
}
}
else {
if (isset($nid_cache[$cache_string])) {
return $nid_cache[$cache_string];
}
elseif (isset($node_cache[$cache_string])) {
// If the node cache stores the same string, retrieve only the nids and
// return them.
foreach ($node_cache[$cache_string] as $nid => $node) {
$return[$nid] = $node->name;
}
// Cache extracted results.
$nid_cache[$cache_string] = $return;
return $return;
}
}
// Results have not been cached.
$tids = implode(', ', $tids);
$result = db_query("SELECT n.nid, t.name FROM {nat} n INNER JOIN {term_data} t USING (tid) WHERE n.tid IN (". db_placeholders($tids) .")", $tids);
while ($node = db_fetch_object($result)) {
if ($get_nodes) {
$return[$node->nid] = node_load($node->nid);
}
else {
$return[$node->nid] = $node->name;
}
}
if ($get_nodes) {
$node_cache[$cache_string] = $return;
}
else {
$nid_cache[$cache_string] = $return;
}
}
return $return;
}
Thanks in advance!
Edit: Try based on the first answer:
foreach (nat_get_nids($termid) as $nid => $node_name) {
}
print $node_name;
It looks like nat_get_nids is returning an associative array, so your for loop should look like
foreach (nat_get_nids($termid) as $nid => $node_name) {
...
}
$nids = nat_get_nids(array($termid));

I would to create a recursive function in order to retrieve data from an array and to organize then.
However I have some difficulties to create the right logic. The principle must be apply to any sub level until it ends or nothing is found.
I want to prevent this kind of code by repeating a foreach inside a foreach...:
$cats = get_categories($args);
$categories = array();
foreach($cats as $cat){
$parent = $cat->category_parent;
if ($parent) {
$categories['child'][$parent][$cat->cat_ID] = $cat->name;
} else {
$categories['parent'][$cat->cat_ID] = $cat->name;
}
}
}
if (isset($categories['parent']) && !empty($categories['parent'])) {
foreach($categories['parent'] as $id => $cat){
$new_cats[$id]['title'] = $cat;
if (isset($categories['child'][$id])) {
foreach($categories['child'][$id] as $child_id => $child_cat){
$new_cats[$child_id]['title'] = $child_cat;
$new_cats[$child_id]['parent_id'] = $id;
if (isset($categories['child'][$child_id])) {
foreach($categories['child'][$child_id] as $sub_child_id => $sub_child_cat){
$new_cats[$sub_child_id]['title'] = $sub_child_cat;
$new_cats[$sub_child_id]['parent_id'] = $child_id;
}
}
}
}
}
}
}
May be this code help you to get idea for formatting your desired array format.
<?php
// Main function
function BuildArr($arr)
{
$formattedArr = array();
if(!empty($arr))
{
foreach($arr as $val)
{
if($val['has_children'])
{
$returnArr = SubBuildArr($val['children']); // call recursive function
if(!empty($rs))
{
$formattedArr[] = $returnArr;
}
}
else
{
$formattedArr[] = $val;
}
}
}
return $formattedArr;
}
// Recursive Function( Build child )
function SubBuildArr($arr)
{
$sub_fortmattedArr = array();
if(!empty($arr))
{
foreach($arr as $val)
{
if($val['has_children'])
{
$response = SubBuildArr($val['children']); // call recursive
if(!empty($response))
{
$sub_fortmattedArr[] = $response;
}
}
else
{
$sub_fortmattedArr[] = $arr;
}
}
return $sub_fortmattedArr;
}
}
?>

i'm getting error with metadata wrapper.
i have a field test => entity reference multiple which is a selection list.I get the following Error EntityMetadataWrapperException : Invalid data value given. Be sure it matches the required data type and format.
$account = entity_load_single('user', $user->uid);
$acc_wrapper = entity_metadata_wrapper('user', $account);
$list = $acc_wrapper->test->value();
$exists = FALSE;
if (!empty($list)) {
foreach ($list as $item) {
if ($item->nid == $form_state['storage']['node']->nid) {
$exists = TRUE;
break;
}
}
}
if (!$exists) {
if (!$list) {
$list = array();
$list[] = $form_state['storage']['node']->nid;
}
$acc_wrapper->test->set($list);
$acc_wrapper->save();
1rst quick tips
$account = entity_load_single('user', $user->uid);
$acc_wrapper = entity_metadata_wrapper('user', $account);
You don't need to load the entity unless you need it loaded after (Or it's already loaded). All you need is the id, and let entity_metadata_wrapper magic operate.
$acc_wrapper = entity_metadata_wrapper('user', $user->uid);
I think your error is here
if (!$list) {
$list = array();
$list[] = $form_state['storage']['node']->nid;
}
$list is always initiated because of "$list = $acc_wrapper->test->value();", so you never fullfill the condition, and then you are trying to set it back and save it (because you are missing a '}' )... Makes no sense...
Could try this version ?
$acc_wrapper = entity_metadata_wrapper('user', $user->uid);
$list = $acc_wrapper->test->value();
$exists = FALSE;
if (!empty($list)) {
foreach ($list as $item) {
if ($item->nid == $form_state['storage']['node']->nid) {
$exists = TRUE;
break;
}
}
}
if (!$exists && !$list) {
$list = array($form_state['storage']['node']->nid);
$acc_wrapper->test = $list;
$acc_wrapper->save();
}
have no idea my result return nothing
if ($stmt2->execute()) {
$photo_items = $stmt2->get_result();
while ($imgArray = $photo_items->fetch_array()) {
}
echo $imgArray[] = $imgArray;
}
and I also tried this
echo $imgArray[] = $imgArray['mycolname'];
Try
while ($img = $photo_items->fetch_array()) {
$imgArray[] = $img;
}
To view the array elements, try:
print_r($imgArray);
I have been searching around for some time but cannot seem to find an answer to my problem.
I have a deep nested array that I need to turn into a nested menu.
https://gist.github.com/anonymous/98e0dcf4f2aef40a1da6
I would like it to end up as something like the following.
https://gist.github.com/anonymous/a0dd4c7d047f11a5ce82
class foo {
function NavigationBuild($routes, $child = false) {
if ($child) {
foreach($routes as $route = > $row) {
if (is_array($row['children'])) {
$output. = self::NavigationBuild($row['children'], true);
} else {
$output. = "<li>".$val['route']."MEEEEE</li>";
}
}
} else {
$output. = '<ul>';
foreach($routes as $route = > $row) {
if (!strlen($row['parent'])) {
$output. = "<li>".$route."</li>";
}
foreach($row['children'] as $key = > $val) {
if (is_array($val['children'])) {
$output. = self::NavigationBuild($val['children'], true);
} else {
$output. = "<li>".$val['route']."MEEEEE</li>";
}
}
}
$output. = '</ul>';
}
return $output;
}
}
Figured it out - seems some sleep was needed.
Thanks to all USEFUL input
I have two database tables, one for allowances and one for deductions. I want to calculate net salaries.
I'm using CodeIgniter. Here's my current code:
function get_allowances($eid)
{
$this->db->from('allowances');
$this->db->where('eid',$eid);
$query = $this->db->get();
if($query->num_rows()==1)
{
return $query->row();
}
else
{
//Get empty base parent object, as $item_id is NOT an item
$salary_obj=new stdClass();
//Get all the fields from items table
$fields = $this->db->list_fields('allowances');
foreach ($fields as $field)
{
$salary_obj->$field='';
}
return $salary_obj;
}
}
function get_deductions($eid)
{
$this->db->from('deductions');
$this->db->where('eid',$eid);
$query = $this->db->get();
if($query->num_rows()==1)
{
return $query->row();
}
else
{
//Get empty base parent object, as $item_id is NOT an item
$salary_obj=new stdClass();
//Get all the fields from items table
$fields = $this->db->list_fields('deductions');
foreach ($fields as $field)
{
$salary_obj->$field='';
}
return $salary_obj;
}
}
and in controller,
function net_salary($eid)
{
$allownces[] = $this->Salary->get_allowances($eid);
$deductions[] = $this->Salary->get_deductions($eid);
return $net_salary = array_sum($allownces) - array_sum($deductions);
}
My net_salary() function gives me a result of 0. What am I doing wrong, and how can I fix it?
Your models with plural names are only going to return a single object.
so what you are ending up with is...
Array
(
[0] => allowance_object
)
and
Array
(
[0] => deduction_object
)
While we really need the schema of your database try this (and make same edits for deductions)...
function get_allowances($eid)
{
$this->db->from('allowances');
$this->db->where('eid',$eid);
$query = $this->db->get();
if($query->num_rows()==1)
{
return $query->row_array(); //<--- return an Array
}
else
{
// make an array instead of object
$salary_obj = array();
//Get all the fields from items table
$fields = $this->db->list_fields('allowances');
foreach ($fields as $field)
{
$salary_array[$field] = 0; //<---- add array keys and set to integer 0 instead of empty string.
}
return $salary_array;
}
}
then in your net_salary function
function net_salary($eid)
{
$allownce = $this->Salary->get_allowances($eid);
$deduction = $this->Salary->get_deductions($eid);
return array_sum($allownce) - array_sum($deduction);
}
Try something like this:
function get_values($eid, $table_name)
{
$this->db->where('eid',$eid);
$query = $this->db->get($table_name);
$salary_obj = $query->result();
$values = array();
foreach($salary_obj as $row){
$values[] = $row->value_column_name;
}
return $values;
}
where value_column_name is the name of the table column (filedname) where the desired value stands.
call in controller:
function net_salary($eid)
{
$allownces = $this->Salary->get_values($eid, 'allowances');
$deductions = $this->Salary->get_values($eid, 'deductions');
return $net_salary = array_sum($allownces) - array_sum($deductions);
}
