[ SOLUTION] Create Hooks in 6 easy steps!

[sperio]

Took me quite a while and lots of meddling to figure this out... thought I would share with the rest of you guys on how to create a hook so u can NOT waste the number of hours like I did :)


1. Goto your database and modify ps_hook... (ps_ is what I named my database, so it can be replaced by what you named yours.)


2. find the last id_hook number and insert a new number after with the hook that you want to name e.g. I name it 'cat'


3. goto the php of the pages you want the hook to be in... e.g footer.php


4. insert 'HOOK_CAT' => Module::hookExec('cat'), into the below

$smarty->assign(array(
        'HOOK_RIGHT_COLUMN' => Module::hookExec('rightColumn'),
        'HOOK_FOOTER' => Module::hookExec('footer'),
        'content_only' => intval(Tools::getValue('content_only'))));
        $smarty->display(_PS_THEME_DIR_.'footer.tpl');

5. this is the final code...

$smarty->assign(array(
        'HOOK_RIGHT_COLUMN' => Module::hookExec('rightColumn'),
        'HOOK_FOOTER' => Module::hookExec('footer'),
        'HOOK_CAT' => Module::hookExec('cat'),
        'content_only' => intval(Tools::getValue('content_only'))));
        $smarty->display(_PS_THEME_DIR_.'footer.tpl');

6.insert {$HOOK_CAT} into where you want in footer.tpl and you are in business


NOTE : For the hook to appear YOU HAVE TO assign the array in the page's php... Would be good if we can have a master HOOK array list...

I want to re-position the adv block to center content area, I have followed you instruction, but got no result.
i have found in blockadvertising.php
line no 19
function install()
{
if (!parent::install())
return false;
if (!$this->registerHook('rightColumn') OR !$this->registerHook('leftColumn') OR !$this->registerHook('adv'))
return false;
return true;
}
Is there any way to display the Advertisement block in center content area below "featured products" ?? :coolsmile:

[SotEW]

Well, if you want to have the advertising in your home page, in the center area, you don't have to add a new Hook, because there is the 'home' hook.

You will have to change your function install() in blockadvertising with :

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

And add the function :

function hookHome($params)
    {
        return $this->hookRightColumn($params);
    }

But may I suggest you to use my module instead ? you'll be able to add and modify elements like swf files or pictures with link on it (juste like blockadvertising) in different places (like home, top, left column, right column, and footer.). You can download it >> HERE <<

And, for sperio : This is a good solution to add new Hooks, and I'm working on finding a global array. I'll make some tests soon.

thanks for tutorial

And if i want Block Specials and New Product Block in Homepage? I have tried this code to blockspecials.php but the modules page in the admin side is blank.

[SotEW]

DannyIDC, If your modules page in the admin side is blank, it's because you put a mistake in blockspecials.php or blocknewproducts.php.

Reset your files and try again ;)

[DannyIDC]

See the file please and tell me where's the problem, please :)

You've got two little mistakes :

you forgot one dollar here : (line 27)

if (!$this->registerHook('rightColumn') OR !$this->registerHook('leftColumn') OR !$this->registerHook('home'))

and a bracet at the end

    function hookHome($params)
        {
        return $this->hookRightColumn($params); 
       }

}                    << here
?>

Don't forget to comment the hook you don't want in the install function. (with the file you give me, you've got the blocspecials in the left column, AND in the right column, AND in the home.)

Don't forget also that you will not display the specials the same way in a column or in the home !! I suggest you to replace the function hookHome with a duplicate of the hookRightColumn function, and rename the .tpl returned (and create it.)

Gook Luck !!

As I was browsing through this thread I realized you never explained how to register a module with your new custom hook. I was attempting to insert the permanent links block into a new hook below the top and I used the following code:

I replaced

if (!$this->registerHook('top'))

with

if (!$this->registerHook('top') or !$this->registerHook('upperColumn'))

AND

I inserted this function

function hookUpperColumn($params)
    {
        return $this->hookLeftColumn($params);
    }

It actually worked, but I'm not sure why. I understand that !$this->registerHook('upperColumn') would install the module in the hook with 'upperColumn' as an ID, but what is the relevance of function hookUpperColumn? I don't see the module calling it anywhere.

cheers,
Swift


EDIT: Actually I was mistaken. The module is being displayed in the center column, why?

I am trying all I can to put the newsletter block in the center of a page. I insert a file into database named centerColumn, and I used the blocknewsletter as base, and I changed the hook from left to center. But I type www.mydomain.com/blocknewsletter.php, it has error. And I type www.mydomain.com/modules/blocknewsletter/blocknewsletter.php, it said file not find. Please help. How can I just put the newsletter block in a page in the center by itself? This is my third day at work. My boss want to put it in the page and put a coupon image on the page. Please help, otherwise I will lost my work.Please help.

[visua]

I too am trying to move the newsletter block. I want it to span 100% width below my content area, so on the top of my footer. But I seem to be having some serious problems! Any help would be greatly appreciated.

I have a feeling once I learn how to customize the blocks and call them individually designing for PrestaShop will be that much better :)

Thanks.

Thanks for your post, it helped me create custom hooks but left out one important note:

For each module (or at least the module I needed to mod the manufactures module) you want to have appear on the hook you have to manually edit two areas:

*My custom hook is called "brand", I swapped it out for the leftColumn positions

1) The install line:

 function install()
    {
        parent::install();
        $this->registerHook('brand');
        Configuration::updateValue('MANUFACTURER_DISPLAY_TEXT', true);
        Configuration::updateValue('MANUFACTURER_DISPLAY_TEXT_NB', 5);
        Configuration::updateValue('MANUFACTURER_DISPLAY_FORM', true);
    }

2) The params area

function hookbrand($params)
    {
        global $smarty, $link;
        
        $smarty->assign(array(
            'manufacturers' => Manufacturer::getManufacturers(),
            'link' => $link,
            'text_list' => Configuration::get('MANUFACTURER_DISPLAY_TEXT'),
            'text_list_nb' => Configuration::get('MANUFACTURER_DISPLAY_TEXT_NB'),
            'form_list' => Configuration::get('MANUFACTURER_DISPLAY_FORM'),
        ));
        return $this->display(__FILE__, 'blockmanufacturer.tpl');
    }

Hope this helps others who were as frustrated as I was!

I can't seem to get the hook to show up in the backend in modules>position. I've already added my hook definition in my database and also to the footer.php in the root folder. What else am I missing?

Thanks!
