Some general questions

[garrettheel]

Okay, nobody seems to be able to help me in the other place so I'll ask here. I am new to the smarty template system and would really appreciate some help in modifying a theme I’m making. The first question I have is how to define different sidebar settings for different pages.. E.g on the home page I do not want any sidebars and on the products page I want the left side bar. How can I change which sidebars appear on which pages? I will post any more questions I have in here as I come across them.

Also, what is the smarty way of outputting each of the categories and the id for them so I can link

e.g
{foreach $category}
{$category_name}
{/foreach}

I’d really appreciate the help! Thanks

first off if your starting a new theme my advice would be to do your own CSS
use some of the current css in global.css then create you own styles in a new defined style sheet

As well as developing modules I am currently working on 2-3 bespoke themes for members on here
if you want to do it yourself I can advice you, otheriwse I can do this for you for a small fee
either provide your own concept or I will work on a new graphics design concept the choice is yours

PM if you need me ;-)

[garrettheel]

Thanks for your reply. I'm not interested in paying as I am a developer and am customizing a Prestashop template. I would just like some help with how to define which pages have which sidebars and the smarty way of outputting categories. This is only a couple of lines of code and I think it will be very easy for someone who knows how to do it.

[ejectcore]

Do you want the catgegory to relate using $_GET['id_category'] :question:

[ejectcore]

If you can explain clearly what your trying to do possibly provide visuals I will try to help out the best way I can ;-)

[garrettheel]

Okay here's an example of the home page.

http://img.skitch.com/20080807-1x1yd43gmgk7ei54tqrirwnh5u.jpg

As you can see from the picture, I want to remove the sidebars (both of them) only on the front page. I know this is done by removing the {HOOK_LEFT} stuff but that is kept in the header which is used on all pages, is there some code I can use to remove the sidebars from only pages I specify? E.g the index.tpl page.

Secondly, I just want to know the way to output a list of categories and the way to output a list of sub categories and their ID, like in the example I gave before. Something like {foreach $category} and then I can do {$category} and then link it to the actual category with
Thanks

[ejectcore]

OK I will break this down into stages

1) All template files (tpl) are defined in there corrosponding php files

Lets take a section of code from the block catgeories module for example:-

       $rootCateg = Category::getRootCategory();
       $blockCategTree = $rootCateg->recurseLiteCategTree(intval(Configuration::get('BLOCK_CATEG_MAX_DEPTH')));
       $isDhtml = (Configuration::get('BLOCK_CATEG_DHTML') == 1 ? true : false);

       if (isset($_GET['id_category']))
       $smarty->assign('currentCategoryId', intval($_GET['id_category']));
       $smarty->assign('blockCategTree', $blockCategTree);
       $smarty->assign('branche_tpl_path', _PS_MODULE_DIR_.'blockcategories/category-tree-branch.tpl');
       $smarty->assign('isDhtml', $isDhtml);

To break this down what we have is :-

Most functions are first defined to use with Pretsahop in the Classes directory

a) $rootCateg = Category::getRootCategory();
now this will fetch all the catgeories from the getRootCategory function
located on line 432 in classes/category.php (all functions related to catgeories can be found here & called upon anywhere within Prestashop
As you know the string $rootCateg is just a name you choose to define this function.

$blockCategTree = $rootCateg->recurseLiteCategTree(intval(Configuration::get('BLOCK_CATEG_MAX_DEPTH')));
what this does is fetches all subcategories defined by our first function again this function can be located line 128 in classes/category.php

function recurseLiteCategTree($maxDepth = 3)
notice intval(Configuration::get('BLOCK_CATEG_MAX_DEPTH')) takes this value from the admin configuration
doing this manually would also work $blockCategTree = $rootCateg->recurseLiteCategTree(2); // (shows maximum depth of catgeories to be 2)

Once you understand the way functions & the classes work everything else should be straight forward ;-)

c) if (isset($_GET['id_category'])) This one expalins it self

Now on to the smarty template engine
$smarty->assign('currentCategoryId', intval($_GET['id_category']));
$smarty->assign('blockCategTree', $blockCategTree);
$smarty->assign('branche_tpl_path', _PS_MODULE_DIR_.'blockcategories/category-tree-branch.tpl');

All we are doing here is defining the php varible to smarty
currentCategoryId enclosed by single speech marks is the name you wish to set for you php variable to be called
you then need a comma & space then all you do is enter your php variable followed by the semi colon as you usely do in PHP

I will go through the template stage with you later
hopefully this is a good starting point for you

Also i think the easiest method for hiding column would be using exceptions.
Unfortuntly there is no current way to edit these once set without trnasplanting the module & setting up the exceptions unless you want to play around with the DB is which case you will find them located ps_hook_module_exceptions

Hope this helps ;-)

[garrettheel]

Hi, thanks for your help. THe ps hook module exceptions was what I was looking for thanks, I've got that worked out now.

Now I just need to fix up the other things.. I can't find a variable that I can use in the blockcategories module that will get me the subcategories of ONLY the current main category (e.g Home->iPods from the default install). I only want the subcategories for the current active category. How can I do this? I couldn't seem to get it from what you posted.

Also, in the header.tlp I need a variable that will get me all of the main categories (like iPods again) and their corresponding links so I can put it in the navigation. I wish I had time to get my hands dirty with smarty but I have a pretty tight deadline to have this project completed and I just need to get a few things working so it'd be a huge help if anyone could tell me these things.

[ejectcore]

You will be better off creating a module instead of putting this in header.tpl & then assign this to Hook Top
you PHP will be no good without modifying the template files.

Please post you current cose & possibly a visual so I can see what your actually tring to acheive here ;-)

[ejectcore]

This is infact the variable used for sub categories, there are a few other options which you can look up in classes/category.php
but if you use $blockCategTree = $rootCateg->recurseLiteCategTree

then just do something like this in your template file again this would be better as a sepearate module

{foreach from=$blockCategTree.children item=child name=blockCategTree}
you template code here ...
{/foreach}

[garrettheel]

Well I need to be able to get the categories in the header.tlp so that I can add all of the main categories to my menu. Which file do I need to assign the variable to in order to access the categories from the header.tlp file?

I don't have the code with me right now, I'll get it for you when I get home in a few hours but here's a picture with some details on how I want to do things.

[garrettheel]

Okay, I've solved one of my problems with getting all the categories for the menu. All I need to know is where to assign a variable so I can make it available in my header.tlp file. (No, I'm not interested in making a module for the header, I just need something small and a module is overkill). So where can I put the $smarty->assign() code so that it is available in header.tlp?

Thanks!

[ejectcore]

I have never tried this from the header but I guess you would insert yur code in header.php
also looking at your visual the center column does not stretch across the homepage this shoudl help you

for example we want 2 columns on the homepage then 3 on the rest of the pages

header.tpl

{if $page_name == "index"}{/if}
{if $page_name != "index"}{/if}

[garrettheel]

Hi, thanks for your reply. I figured I would use a header.php file, but I was wondering what I would need to put in it.

E.g what would it look like?

<?php

class something? extends something? {

function __construct() {
smarty->assign();
}



is that the basic structure of the header.php file that I'll need to make?

[ejectcore]

here's an example from my latest module to fetch the catgeories

<?php

class CategoriesBar extends Module
{
   function __construct()
   {
       $this->name = 'categoriesbar';
       $this->tab = 'Blocks';
       $this->version = 0.1; // Module created by Alpha Media 05/08/08

       parent::__construct(); /* The parent construct is required for translations */

       $this->page = basename(__FILE__, '.php');
       $this->displayName = $this->l('Top Categories Bar');
       $this->description = $this->l('Adds a Bar featuring product categories');
   }

   function install()
   {
       if (!parent::install())
           return false;
       if (!$this->registerHook('top'))
           return false;
       return true;
   }


   /**
   * Returns module content for header
   *
   * @param array $params Parameters
   * @return string Content
   */
   function hookTop($params)
   {
       global $smarty;

       //construct categories
       $depth = 1;
       $rootCateg = Category::getRootCategory()->recurseLiteCategTree($depth);

       if (isset($_GET['id_category']))
       $smarty->assign('currentCategoryId', intval($_GET['id_category']));
       $smarty->assign('bar_tpl_path', _PS_MODULE_DIR_.'categoriesbar/category-bar-level.tpl');
       $smarty->assign('categoriesLevel', $rootCateg);
       return $this->display(__FILE__, 'categoriesbar.tpl');
   }
}

?>

It much easier to create & assign a module!
the code above is not finished & please no one try to use this as the full module zip will be avialble next week roll:
Hope that helps :

[garrettheel]

Ah, a module is too complex for me at the moment. I only have a short amount of time so I want to do it the simplest way possible. Here's my header.php file

<?php

class Categories extends whatgoeshere? {

   __construct() {
       global $smarty

       $smarty->assign('test', 'test');

   }
}

?>

Basically, this is just so that I can put {$test} in my header.tlp and it will work. Can you show me what to do so this will work?

[ejectcore]

You already have $smarty->assign so you need to add to the array no need to create a new class, this is really only used for module creation

$test = 'categories test';

$smarty->assign(array(
   'HOOK_HEADER' => Module::hookExec('header'),
   'HOOK_LEFT_COLUMN' => Module::hookExec('leftColumn'),
   'HOOK_TOP' => Module::hookExec('top'),
               'test'  =>  $test,

               'static_token' => Tools::getToken(false),
   'token' => Tools::getToken()
));

[garrettheel]

I added that code to header.php and I still couldn't get the smarty variable in my header.tlp using {$test}
Any more ideas?

Edit: Also, I think smarty is not seeing the header.php file, perhaps there's some extra code I have to add somewhere? Because when I just put some plain html in the header.php it doesn't show up on the page like it should.

[ejectcore]

it works this end :roll:

Make sure you type this in the same case for both template & the php page because this will be case sensitive
if this still doesn't work please post your header.php code & also a snippet from your header.tpl

[garrettheel]

Hmm, it's the same case..

These are the files: (they are both in the same directory in /themes/theme_name/)

PS - you can see where i've called the test variable just after the end of the head tag </head>

header.php

<?php
$test = 'categories test';

$smarty->assign(array(
   'HOOK_HEADER' => Module::hookExec('header'),
   'HOOK_LEFT_COLUMN' => Module::hookExec('leftColumn'),
   'HOOK_TOP' => Module::hookExec('top'),
               'test'  =>  $test,

               'static_token' => Tools::getToken(false),
   'token' => Tools::getToken()
));
?>

header.tpl

<?php

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="{$lang_iso}">
   <head>
       <base href="{$protocol}{$smarty.server.HTTP_HOST|escape:'htmlall':'UTF-8'}{$base_dir}" />

[ejectcore]

Where is your test variable in header.tpl :question:

try putting it somewhere like this

{$test}
{$HOOK_LEFT_COLUMN}

[garrettheel]

It's already there Look just past half way after the HOOK_HEADER

[ejectcore]

I see but it's not in your body :wow:

[garrettheel]

I just put it in various different places in the header.tpl file and still nothing. i think it's a problem with smarty not seeing the header.php file, I feel like there must be some code that must be added because putting plain html in the header.php file doesn't output either..

[ejectcore]

No it defferently works for me :roll:

Here's what your header.php should look like

<?php
require_once(dirname(__FILE__).'/init.php');

/* CSS */
$css_files[_THEME_CSS_DIR_.'global.css'] = 'all';

$test = 'categories test';

/* Hooks are volontary out the initialize array (need those variables already assigned) */
$smarty->assign(array(
   'test'  => $test,
   'HOOK_HEADER' => Module::hookExec('header'),
   'HOOK_LEFT_COLUMN' => Module::hookExec('leftColumn'),
   'HOOK_TOP' => Module::hookExec('top'),
   'static_token' => Tools::getToken(false),
   'token' => Tools::getToken()
));

if(isset($css_files) AND !empty($css_files)) $smarty->assign('css_files', $css_files);
if(isset($js_files) AND !empty($js_files)) $smarty->assign('js_files', $js_files);

/* Display a maintenance page if shop is closed */
if (isset($maintenance))
{
   header('HTTP/1.1 503 temporarily overloaded');
   $smarty->display(_PS_THEME_DIR_.'maintenance.tpl');
   exit;
}

$smarty->display(_PS_THEME_DIR_.'header.tpl');

?>

[ejectcore]

Why are you using php code blocks within the template files when header.php has already defined the variables :question:

[garrettheel]

what are you talking about? I created my own header.php file because one didn't exist in the template directory

[ejectcore]

No don't do that!
You are suppose to use the one found in the root all template files relate to php files found in the root no wonder it doesn't work for you :roll:

[garrettheel]

ah, got it! haha, i tried to create my own header.php (why i thought more code had to be added) in the template directory

[garrettheel]

Okay, now I just need help with one more thing. This is what I was talking about before, I need a variable that will get me all the children for the current category. E.g if the url has id_category=3, then this variable will have all of the children for variable 3 in it. Can this be done?

[ejectcore]

try something like this in your header.php
although this is what i use for my module may need some tweaking
have you ever worked with smarty before & used FOREACH statements

If not you will stuggle with this :roll:

$test = 'categories test';
$depth = 2;
$rootCateg = Category::getRootCategory()->recurseLiteCategTree($depth);
if (isset($_GET['id_category']))

   $smarty->assign('currentCategoryId', intval($_GET['id_category']));
   $smarty->assign('sub_tpl_path', _PS_MODULE_DIR_.'categoriesbar/category-bar-level.tpl');
   $smarty->assign('categoriesLevel', $rootCateg);

/* Hooks are volontary out the initialize array (need those variables already assigned) */
$smarty->assign(array(
   'test'  => $test,
   'HOOK_HEADER' => Module::hookExec('header'),
   'HOOK_LEFT_COLUMN' => Module::hookExec('leftColumn'),
   'HOOK_TOP' => Module::hookExec('top'),
   'static_token' => Tools::getToken(false),
   'token' => Tools::getToken()
));

if (isset($_GET['id_category']))
$smarty->assign('currentCategoryId', intval($_GET['id_category']));
$smarty->assign('bar_tpl_path', _PS_MODULE_DIR_.'categoriesbar/category-bar-level.tpl');
$smarty->assign('categoriesLevel', $rootCateg);
return $this->display(__FILE__, 'categoriesbar.tpl');
}
}
