Show all categories in a CMS Page?

[Chetanilead]

Hello All,

 

I want to display all the categories added from the admin section on a front CMS page.

 

Can anyone help me ? Its urgent.

 

Thanks in advance.

I believe the only way to do it is by editing the cms controller, and if the cms page id matches the one you need, you can use Category::getCategories($id_lang) to get all of them. Assign to the tpl, and display inside cms.tpl is that smarty variable has been assigned

Hi nemo1,

 

Thanks for the quick reply . I am new to prestashop. Could you please clarify more?

The Changes which U have suggested my affect the core files of prestashop right?

If yes then is there any other way to implement it without modifying core scripts.

 

Thanks

[NemoPS]

Well you can use override, it's a bit complex to explain in a forum topic, if you don't feel confident you may hire someone to do it for you from the paid jobs section

[Chetanilead]

If you can provide me some sample knowledge I am capable in doing that I have knowledge of other PHP frameworks and CMS. But I am new in prestashop

getCategories() function is static function so in .tpl file you can use foreach loop on Category::getCategories()

 

 

something like:

{foreach from=Category::getCategories() item=category}
{$category.name}<br/>
{/foreach}

[NemoPS]

Sure! 

 

check out this tut on overrides:

http://doc.prestashop.com/display/PS15/Overriding+default+behaviors#Overridingdefaultbehaviors-Overridingacontroller

 

You have to override the CMSController.php file, in override/controllers/front

 

In the initContent method, check if Tools::getValue('id_cms') equals the id of the cms page you want the list to appear. If it does use

 

Category::getCategories($id_lang) 

 

To get categories, then $this->context->smarty->assign('thevariablenameinsmarty',$categories_variable_name);

 

Finally, inside cms.tpl (template folder) if $thevariablenameinsmarty is assigned, display categories

[Chetanilead]

I have studies and created a sample code in my_module\override\controllers\front\CmsController.php

 

In which I have written following code

 

<?php

class MycmsController extends CmsControllerCore{
    public function init()
    {
        $id_cms = (int)Tools::getValue('id_cms');
                echo $id_cms;
                die;
    }

 

  public function initContent()
    {
        $id_cms = (int)Tools::getValue('id_cms');
                echo $id_cms;
                die;
    }
    
}

 

I have also deleted the class_index.php  file from cache folder but still not getting cms page id and it not event die(stops) the execution.

 

Help me please

[NemoPS]

it has to be called cmsController, without "my"

[Chetanilead]

Thanks for the reply but it still not working for me

 

<?php
class cmsController extends CmsControllerCore{
    public function init()
    {
        $id_cms = (int)Tools::getValue('id_cms');
                echo $id_cms;
                die;
    }

 

  public function initContent()
    {
        $id_cms = (int)Tools::getValue('id_cms');
                echo $id_cms;
                die;
    }
    
}

[NemoPS]

Can you check if the override has been moved to main the override/controllers/front folder after installing the module?

[Chetanilead]

I have checked that and it is not moved into that folder . It contains only a single file index.php :(

[NemoPS]

Try reinstalling the module. If it doesn't move yet, move it manually and clear the class index

[Chetanilead]

Hi Nemo thanks for your reply it worked for me but I forgot to thank you.

 

I have a new query in this How can I load a tpl or php file when my CMS page is called.

 

Thanks in advance

[Chetanilead]

Hi

 

I have used  $categories = Category::getCategories(); to get all categories it is working fine for me but I didn't get category image on the tpl file can you please let me know how can I get that image. I am also not getting $category.id_image parameter to get image

 

I got this array for each category :

 

[infos] => Array
(
[id_category] => 13
[id_parent] => 2
[id_shop_default] => 1
[level_depth] => 2
[nleft] => 3
[nright] => 4
[active] => 1
[date_add] => 2014-05-23 01:58:27
[date_upd] => 2014-05-28 02:30:24
[position] => 1
[is_root_category] => 0
[id_shop] => 1
[id_lang] => 1
[name] => Appearance Protection Packages
[description] =>
[link_rewrite] => appearance-protection-packages
[meta_title] =>
[meta_keywords] =>
[meta_description] =>
)

 

How can I get image for this category please help.

[NemoPS]

Like this:

 

{$link->getCatImageLink($category->link_rewrite, $category->id_image, 'category')}

[godlo]

 

getCategories() function is static function so in .tpl file you can use foreach loop on Category::getCategories()

 

 

something like:

{foreach from=Category::getCategories() item=category}
{$category.name}<br/>
{/foreach}

 

in this way the only thing to override is the .tpl and not the cmsController.php?

 

[NemoPS]

Correct, but I would not use logic in templates like that honestly

Hello did you solve that? I know it's been a long time ago but, I'm trying to do the same now in prestashop 1.7.5.1.

@Chetanilead would it be possible to get the module you developed?

Thanks.
