Restrict menu tree to first level - drupal

I've been struggling a while in order to get my primary links to display only the first level entries (roots). I have the following code in my template.php :
I've tried changing the $level variable to 0 but no effect. I don't know where (the hell) to stop the recursion.
function supertheme_navigation_links($menu_name, $level = 2) {
// Don't even bother querying the menu table if no menu is specified.
if (empty($menu_name)) {
return array();
}
// Get the menu hierarchy for the current page.
$tree_page = menu_tree_page_data($menu_name);
// Also get the full menu hierarchy.
$tree_all = menu_tree_all_data($menu_name);
// Go down the active trail until the right level is reached.
while ($level-- > 0 && $tree_page) {
// Loop through the current level's items until we find one that is in trail.
while ($item = array_shift($tree_page)) {
if ($item['link']['in_active_trail']) {
// If the item is in the active trail, we continue in the subtree.
$tree_page = empty($item['below']) ? array() : $item['below'];
break;
}
}
}
return supertheme_navigation_links_level($tree_page, $tree_all);
}
/**
* Helper function for supertheme_navigation_links to recursively create an array of links.
* (Both trees are required in order to include every menu item and active trail info.)
*/
function supertheme_navigation_links_level($tree_page, $tree_all) {
$links = array();
foreach ($tree_all as $key => $item) {
$item_page = $tree_page[$key];
$item_all = $tree_all[$key];
if (!$item_all['link']['hidden']) {
$l = $item_all['link']['localized_options'];
$l['href'] = $item_all['link']['href'];
$l['title'] = $item_all['link']['title'];
if ($item_page['link']['in_active_trail']) {
if (empty($l['attributes']['class'])) {
$l['attributes']['class'] = 'active-trail';
}
else {
$l['attributes']['class'] .= ' active-trail';
}
}
if ($item_all['below']) {
$l['children'] = supertheme_navigation_links_level($item_page['below'], $item_all['below']);
}
// Keyed with unique menu id to generate classes from theme_links().
$links['menu-'. $item_all['link']['mlid']] = $l;
}
}
return $links;
}
/**
* Return a themed set of links. (Extended to support multidimensional arrays of links.)

}
if (isset($link['href']) && ($link['href'] == $_GET['q'] || ($link['href'] == '<front>' && drupal_is_front_page()))) {
$class .= ' active';
}
// Added: if the link has child items, add a haschildren class
if (isset($link['children'])) {
$class .= ' haschildren';
}
$output .= '<li'. drupal_attributes(array('class' => $class)) .'>';
if (isset($link['href'])) {
// Pass in $link as $options, they share the same keys.
$output .= l($link['title'], $link['href'], $link);
}

Not totally sure what you meant when you said you tried to change $level to 0, but then it will not enter in the loop: while ($level-- > 0 && $tree_page)
To be able to stop a recursion, the recursive function needs to have an argument with the depth. So INSIDE the recursive function you decide when to stop: if ($depth <1) { return; } and everytime you call the recursive funcion you call it with $depth-1
If you want this functionality 'out-of-the-box', try http://drupal.org/project/menu_block , or get some inspiration from its code: (see menu_tree_depth_trim function)

I believe, that if you set your menu to be non-expanded under menu settings that Drupal will handle the rest for you.
Another option would be to use nice menus which mainly is used to show expandable menus, but also can be used to control the level of menu expansion.

How to override the Drupal plugin's function?

I am new in Drupal.
I am using imagemagick plugin for modify images. My problem is when it resize GIF image the image got messed up. I search the solution on internet i found the changes regarding that.
but i don't want to write code changes directly to plugins module file.
I want to override it's image_imagemagick_resize() function. I can not figure out how to Override it and where to put it's override function.
Default Function :-
function image_imagemagick_resize(stdClass $image, $width, $height) {
$image->ops[] = '-resize ' . (int) $width . 'x' . (int) $height . '!';
$image->info['width'] = $width;
$image->info['height'] = $height;
return TRUE;
}
Override Function:
function imageapi_imagemagick_image_resize(&$image, $width, $height) {
$extra = '';
if($image->info['mime_type'] == 'image/gif') {
$extra = '-coalesce ';
}
$image->ops[] = $extra . '-resize '. (int) $width .'x'. (int) $height .'!';
$image->info['width'] = $width;
$image->info['height'] = $height;
return TRUE;
}
Thanks
Hopefully image_imagemagick_resize invokes alter hooks via _image_imagemagick_alter_invoke :
function image_imagemagick_resize($source, $dest, $width, $height) {
$args = array('resize' => '-resize ' . (int) $width . 'x' . (int) $height . '!');
$args = _image_imagemagick_alter_invoke('resize', $source, $args);
return _image_imagemagick_convert($source, $dest, $args);
}
function _image_imagemagick_alter_invoke($op, $filepath, $args) {
foreach (module_implements('imagemagick_alter') as $module) {
$function = $module . '_imagemagick_alter';
$function($op, $filepath, $args);
}
return $args;
}
So you can override the resize parameters by implementing the hook_imagemagick_alter() in a custom module :
function mymodule_imagemagick_alter($op, $filepath, &$args) {
# altering $args...
}

Real dynamic DQL with doctrine in symfony 3.4

I'm trying to achieve a dynamic query with DQL in doctrine. I've checked several post about this subject but all the solutions are static. I want to achieve somethin like this:
$qb->where(
$qb->expr()->orX(
$qb->expr()->like('e.cliente', ':cliente_tag'),
$qb->expr()->like('e.cliente', ':cliente_tag2'),
$qb->expr()->like('e.cliente', ':cliente_tag3')
),
$qb->expr()->orX(
$qb->expr()->like('e.apoderado', ':apoderado_tag'),
$qb->expr()->like('e.apoderado', ':apoderado_tag2'),
$qb->expr()->like('e.apoderado', ':apoderado_tag3')
)
);
but inside a loop like this:
foreach ($options['camposTexto'] as $i => $campoTexto) {
switch ($campoTexto['appliedTo']) {
case 'apoderado': {
$exp = [];
foreach ($campoTexto['tags'] as $tag) {
$exp[] = $qb->expr()->like('e.apoderado', ':apoderado_tag' . $i);
$parameters['apoderado_tag' . $i] = '%' . $tag . '%';
}
if ($isFirst) {
$isFirst = false;
$qb->where($qb->expr()->orX($exp));
} else {
$qb->andWhere($qb->expr()->orX($exp));
}
break;
}
case 'cliente': {
$exp = [];
foreach ($campoTexto['tags'] as $tag) {
$expresiones[] = $qb->expr()->like('e.cliente', ':cliente_tag' . $i);
$parameters['cliente_tag' . $i] = '%' . $tag . '%';
}
if ($isFirst) {
$isFirst = false;
$qb->where($qb->expr()->orX($exp));
} else {
$qb->andWhere($qb->expr()->orX($exp));
}
break;
}
}
}
tags is an array of strings. As you see I passed the array of expresions but doctrine throws me an Exception.
So far so now I have not found any solution to my problem.
Any Idea?
Thanks in advance!
Looking at this post I figured out the solution. It would be something like this:
case 'apoderado': {
$orX = $qb->expr()->orX();
foreach ($campoTexto['tags'] as $y => $tag) {
$orX->add($qb->expr()->like('e.apoderado', $qb->expr()->literal('%' . $tag . '%'))); //<= with literal because I can't set the parameters later in the qb
}
$expresiones[] = $orX;
break;
}
after all the case/break
$andX = $qb->expr()->andX();
$qb->where($andX->addMultiple($expresiones));
return $qb->getQuery()->getResult();

wordpress: overwrite public static function through functions.php

I have tried this article: Modify Wordpress plugin function in functions.php not working.
I have a plugin (Wordpress_seo). It has a folder "frontend" in it and class-breadcrumbs.php file with WPSEO_Breadcrumbs class and a public static function breadcrumb. I need to overwrite it in functions.php.
I am pretty new to wordpress, so I might have missed some solution. Here is my current code:
add_filter('filter_breadcrumb', 'mytheme_breadcrumb');
function mytheme_breadcrumb($before = '', $after = '', $display = true){
if ( ! ( self::$instance instanceof self ) ) {
self::$instance = new self();
}
// Remember the last used before/after for use in case the object goes __toString().
self::$before = $before;
self::$after = $after;
$output = $before . '<!--1-->'.self::$instance->output.'<!--2-->' . $after;
if ( $display === true ) {
echo $output;
return true;
}
else {
return $output;
}
}
I copied the whole function and added the '' for testing purposes, but it doesn't work. Can anyone tell me if I am doing something wrong?
thanks

How to export all rows as CSV in ModelAdmin (SilverStripe 3.1)?

Apparently the GridFieldExportButton only exports the currently visible data-set (paginated). Is there a way to make it export all the rows from a model?
Or alternatively: Is there a way to show all rows (eg. bypass pagination), so that the user can perform an export after showing all the rows? I don't want to show all rows all the time (which would probably be possible by setting ModelAdmin::set_page_length(<ridiculouslyHighNumber>);) but only on demand.
You can override ModelAdmin::getExportFields() to define the columns you want to export.
The method needs to return an array with column name as the key, and the db field as the value.
For example:
class MyCustomModelAdmin extends ModelAdmin {
....
public function getExportFields() {
return array(
'FirstName' => 'FirstName',
'Surname' => 'Surname',
'Age' => 'Age'
);
}
}
Solved it by creating a custom subclass of the GridFieldExportButton and using this for my models. The key is to use $gridField->getList(); instead of $gridField->getManipulatedList(); in the generateExportFileData method.
Here's the complete class for anybody interested:
class GridFieldExportAllButton extends GridFieldExportButton {
/**
* Generate export fields for CSV.
*
* #param GridField $gridField
* #return array
*/
public function generateExportFileData($gridField) {
$separator = $this->csvSeparator;
$csvColumns = ($this->exportColumns)
? $this->exportColumns
: singleton($gridField->getModelClass())->summaryFields();
$fileData = '';
$columnData = array();
$fieldItems = new ArrayList();
if($this->csvHasHeader) {
$headers = array();
// determine the CSV headers. If a field is callable (e.g. anonymous function) then use the
// source name as the header instead
foreach($csvColumns as $columnSource => $columnHeader) {
$headers[] = (!is_string($columnHeader) && is_callable($columnHeader)) ? $columnSource : $columnHeader;
}
$fileData .= "\"" . implode("\"{$separator}\"", array_values($headers)) . "\"";
$fileData .= "\n";
}
$items = $gridField->getList();
foreach($items as $item) {
$columnData = array();
foreach($csvColumns as $columnSource => $columnHeader) {
if(!is_string($columnHeader) && is_callable($columnHeader)) {
if($item->hasMethod($columnSource)) {
$relObj = $item->{$columnSource}();
} else {
$relObj = $item->relObject($columnSource);
}
$value = $columnHeader($relObj);
} else {
$value = $gridField->getDataFieldValue($item, $columnSource);
}
$value = str_replace(array("\r", "\n"), "\n", $value);
$columnData[] = '"' . str_replace('"', '\"', $value) . '"';
}
$fileData .= implode($separator, $columnData);
$fileData .= "\n";
$item->destroy();
}
return $fileData;
}
}
Thanks for this!
I had to use this for Members GF in Security Admin.
Created an extension for anyone interested.
class SecurityAdminExtension extends Extension{
function updateEditForm($form){
$gf = $form->Fields()->fieldByName('Root.Users.Members');
$gfConfig = $gf->getConfig();
$gfConfig->removeComponentsByType('GridFieldExportButton');
$gfConfig->addComponent(new GridFieldExportAllButton());
}
}
I while back, I created a little plugin to make it easy to export DataObjects to CSV or Excel files.
https://github.com/firebrandhq/excel-export
It comes with a button you can add to a grid field.
It's got a dependency on PHP-Excel.

How to apply <span> tag to My Cart top link in magento?

I have changed texts My cart to My Shopping Bag in top links through below code.
public function addCartLink()
{
$parentBlock = $this->getParentBlock();
if ($parentBlock && Mage::helper('core')->isModuleOutputEnabled('Mage_Checkout')) {
$count = $this->getSummaryQty() ? $this->getSummaryQty()
: $this->helper('checkout/cart')->getSummaryCount();
if ($count == 1) {
$text = $this->__('My Shopping Bag (%s)', $count);
} elseif ($count > 0) {
$text = $this->__('My Shopping Bag (%s)', $count);
} else {
$text = $this->__('My Shopping Bag');
}
$parentBlock->removeLinkByUrl($this->getUrl('checkout/cart'));
$parentBlock->addLink($text, 'checkout/cart', $text, true, array(), 50, null, 'class="top-link-cart"');
}
return $this;
}
Now, I want to apply tag to shopping cart quantity.
So, It should look like My Shopping Bag 0. 0 (quantity) should be in red color. So what should I do?
your code is right but in else part its want tricky way.
you can show like this
$text = $this->__('My Shopping Bag (0)');
may its help you
Thanks

<span> can be added directly.
public function addCartLink()
{
$parentBlock = $this->getParentBlock();
if ($parentBlock && Mage::helper('core')->isModuleOutputEnabled('Mage_Checkout')) {
$count = $this->getSummaryQty() ? $this->getSummaryQty()
: $this->helper('checkout/cart')->getSummaryCount();
if ($count == 1) {
$text = $this->__('My Shopping Bag <span>(%s)</span>', $count);
} elseif ($count > 0) {
$text = $this->__('My Shopping Bag <span>(%s)</span>', $count);
} else {
$text = $this->__('My Shopping Bag');
}
$parentBlock->removeLinkByUrl($this->getUrl('checkout/cart'));
$parentBlock->addLink($text, 'checkout/cart', $text, true, array(), 50, null, 'class="top-link-cart"');
}
return $this;
}
