[PRESTASHOP 1.7] I want to display categories outside of ps_categorytree.
Here is the module code:
$allCategories = Category::getNestedCategories(null, $this->context->language->id);
$this->context->smarty->assign( 'allCategories' , $allCategories );
return $this->fetch('module:'.$this->name.'/views/templates/widget/block.tpl');
.tpl file:
{foreach from=$allCategories item=mainCategory}
{$mainCategory.name}
{foreach from=$mainCategory.children item=subCategory}
{$subCategory.name}
{/foreach}
Error: Notice: Undefined index: link
How do I assign a link?
Because of you got the Category as array, not an object.
Try to use mainCategory['link'] instead of mainCategory.link, and so on
UPDATE
I misunderstood the question, sorry!
Try this.
{foreach $allCategories as $mainCategory}
{$link->getCategoryLink($mainCategory.id_category, $mainCategory.link_rewrite)|escape:'html':'UTF-8'}
{/foreach}
If you have'nt $link variable in the smarty file, you should assign it
'link' => $this->context->link,

I use this code in Prestashop
{if (strpos($product.name, 'TVNUMBER1') !== false)}
THIS PRODUCT IS IN SALE
{/if}
So whenever I want to display that certain products are in sale, I have to go line by line, specifying the same product i.e."TVNUMBER1". I want to be able to write an array detailing all the products I have in sale "TV1, TV2, TV3", and get a code like this:
{if (strpos($product.name, '$array') !== false)}
THIS PRODUCT IS IN SALE
{/if}
I've tried similar examples found here, but I can't get them to work, either in Prestashop or in PHP testers online. It looks super simple, but I can't get around it.
I think what you want is the in_array php function, that check if a given $needle is or not in an array.
So what you should do is :
{if (in_array($product.name, '$array') !== false)}
THIS PRODUCT IS IN SALE
{/if}
Then in your controller you can assign the array to smarty :
$arr = array('TVNUMBER1', 'TVNUMBER2', 'TVNUMBER3');
$smarty->assign('myArray', $arr);
It seems you are using Smarty as template engine. So you could do something like this (from the doc).
In the controller
//Give it to the view
$arr = array('TVNUMBER1', 'TVNUMBER2');
$smarty->assign('myArray', $arr);
And in the view
//In the view, loop over the array
{foreach from=$myArray item=productName}
//If your product is among the in-sale ones, show the message
{if (strpos($product.name, productName) !== false)}
THIS PRODUCT IS IN SALE
{/if}
{/foreach}
I have a main array:
$occupations = ['hs','uni','parent'];
and other multiple array of type
$columns_hs;$columns_uni;
etc.
I want to foreach through the "$occupations" array and then foreach through the other arrays but cant seem to get the right syntax.
Here is my code:
{foreach from=$occupations item=ov key=ok}
{foreach from=$columns_`$ov`}
do something
{/foreach}
{/foreach}
I am using smarty 2.
You can try to create your own varible with assign
Declare one array colums
$colums = array(
'hs' => [1,2,3,4],
'uni' => [5,6,7,8]
);
and your code in foreach is
{foreach from=$occupations item=ov key=ok}
{foreach from=$columns[$ov]}
do something
{/foreach}
{/foreach}
This is my codeigniter code for categories and sub categories when i echo the results outside the first foreach or pass results to smarty it only outputs last rows with last main id.
But echo within the first foreach before closing } returns all results.
function getAllCats(){
$this->load->model('mHtml', 'mnMod');
$main_cat = $this->mnMod->getncats();
$all_cat = '';
foreach($main_cat as $mcat){
$all_cat = '<li><h3>'.$mcat->cname.'</h3>';
$sub_cat = $this->mnMod->getscats($mcat->categoryid);
foreach($sub_cat as $scat){
$all_cat .= ''.$scat->cname.'<br />';
}
$all_cat .= '</li>';
}
// echo $all_cat; die;
$this->smarty->assign("nav", $all_cat);
}
Results returned with mymethod.
Power Inverters
Off Grid Pure Sine Wave
Grid Tie String
Micro Grid Tie
Results i want to achieve and pass to smarty variable
Solar Panels
Monocrystalline
Polycrystalline
Flexible Solar
Charge Controllers

I have the same issue what i did i get all parent categories by one mysql query and in another i select all categories, simply i assign variables to smarty and foreach those results against each parent category.
$main_Categories = $this->model->all_categories();
$this->smarty->assign("main_Categories ", $main_Categories );
//On Smarty page
{foreach $main_Categories $cat}
{if $cat->parentid = 'your parent id'} // parent id will be same for all main ids.
{$cat->category_name}<br />
{assign 'cat_id' $cat->cat_id}
{foreach $main_Categories as $sub}
{if $cat_id eq $sub->parent_id}
{$sub->category_name}<br />
{/if}
{/foreach}
{/if}
{/foreach}
Loop through your $main_cats and assign sub_categories for each one. Good practice is to ensure $main_cats is an array before doing this.
Controller:
function getAllCats() {
$this->load->model('mHtml', 'mnMod');
$main_cats = $this->mnMod->getncats();
if(is_array($main_cats))
foreach($main_cats as &$mcat) {
$mcat['subcat'] = $this->mnMod->getscats($mcat->categoryid);
}
$this->smarty->assign("cats", $main_cats);
}
View:
{if $cats}
{foreach from=$cats item=cat}
<li><h3>{$cat.cname}</h3>
{foreach from=$cat item=sub_cat}
{$sub_cat.cname}<br />
{/foreach}
</li>
{/foreach}
{else}
<p>No cats found</p>
{/if}
I want to get a two dimensional array's data and display it in a html file using smarty:
The idea is as following: my array contains several arrays everyone contains the category name in the first offset and the attached links to this category
1-file php
$categories_links = array();//array that contains some catgories name with the attached links
//some dummy data
$categorie1="Horror movies";
$link11="http://www.movie11.com";
$link12="http://www.movie12.com";
$link13="http://www.movie13.com";
$categories_links[] = array($categorie1, $link11, $link12,$link13);
$categorie2="Action movies";
$link21="http://www.movie21.com";
$link22="http://www.movie22.com";
$categories_links[] = array($categorie2, $link21, $link22);
$smarty->assign('categories_links' , $categories_links );
$smarty->display('file.html');
2-file html
{foreach key=categorie item=categorie from=$categories_links}
foreach key=categorie item=categorie from=categorie}
<!--
1.display only the first item in every array as the category name
2.display the rest as the links attached to the above category
//-->
{/foreach}
{/foreach}
Assuming you use Smarty 3 (you haven't mentioned anything about Smarty 2) you can use the following code:
{foreach $categories_links as $categorie}
<p>
{foreach $categorie as $item}
{if $item#first}
<strong>Category name: {$item}</strong><br />
{else}
{$item}
{/if}
{/foreach}
</p>
{/foreach}
Output for this will be:
Category name: Horror movies
http://www.movie11.com http://www.movie12.com http://www.movie13.com
Category name: Action movies
http://www.movie21.com http://www.movie22.com
EDIT
As you mentioned in comment you want solution for Smarty 2 you need to use in you Smarty template file:
{foreach key=id item=categorie from=$categories_links}
<p>
{foreach item=item from=$categorie name=list}
{if $smarty.foreach.list.first}
<strong>Category name: {$item}</strong><br />
{else}
{$item}
{/if}
{/foreach}
</p>
{/foreach}
This will give you output:
Category name: Horror movies
http://www.movie11.com http://www.movie12.com http://www.movie13.com
Category name: Action movies
http://www.movie21.com http://www.movie22.com
(exactly the same as the one in Smarty 3)
I'd refactor the data array to use the category name as a key.
$categories = array(
'Horror movies' => array(
'link1',
'link2',
/...
),
'Action movies' => array(
'link1',
'link2',
/...
),
);
$smarty->assign("categories", $categories);
Then you can use it easily in Smarty
{foreach from=$categories key=category item=links}
Category: {$category}
{foreach from=$links item=link}
{$link}
{/foreach}
{/foreach}
It is much easier to use that way.
I am trying to understand developing web apps with PHP and smarty this is the book
there is a file departments_list.tpl
{* departments_list.tpl *}
{load_presentation_object filename="departments_list" assign="obj"}
{* Start departments list *}
<div class="box">
<p class="box-title">Choose a Department</p>
<ul>
{* Loop through the list of departments *}
{section name=i loop=$obj->mDepartments}
{assign var=selected value=""}
{* Verify if the department is selected to decide what CSS style to use *}
{if ($obj->mSelectedDepartment == $obj->mDepartments[i].department_id)}
{assign var=selected value="class=\"selected\""}
{/if}
<li>
{* Generate a link for a new department in the list *}
<a {$selected} href="{$obj->mDepartments[i].link_to_department}">
{$obj->mDepartments[i].name}
</a>
</li>
{/section}
</ul>
</div>
{* End departments list *}
I do not understand in above file one line which is
{section name=i loop=$obj->mDepartments}
how does name=i works I what is i initialized to and how can a loop start from i,
secondly above file is using a file function.load_presentation_object.php
<?php
// Plug-in functions inside plug-in files must be named: smarty_type_name
function smarty_function_load_presentation_object($params, $smarty)
{
require_once PRESENTATION_DIR . $params['filename'] . '.php';
$className = str_replace(' ', '',ucfirst(str_replace('_', ' ',$params['filename'])));
// Create presentation object
$obj = new $className();
if (method_exists($obj, 'init'))
{
$obj->init();
}
// Assign template variable
$smarty->assign($params['assign'], $obj);
}
?>
in above file a parameter $params has been used in last line
$smarty->assign($params['assign'], $obj);
as far as I can understand from file departments_list.tpl passes on parameter to function.load_presentation_object.php
as
{load_presentation_object filename="departments_list" assign="obj"}
so when following is called
function smarty_function_load_presentation_object($params, $smarty)
$params=depratments_list and $smarty=obj
so how does
$smarty->assign($params['assign'], $obj);
work what is $params['assign'] in above?
{load_presentation_object filename="departments_list" assign="obj"}
translated to php will be:
smarty_function_load_presentation_object(
array(
'filename' => 'departments_list',
'assign' => 'obj'
),
$smarty
);
Every parameters specified in smarty template are passed as associative array in first argument. Second is always current smarty object.
As for
{section name=i loop=$obj->mDepartments}
it is simple for loop:
for ($i=0; $i < count($obj->mDepartments); $i++) {
$current = $obj->mDepartments[$i];
}
