Prestashop | Remove transplant restrictions - hook

So, there's a problem - I need to transplant "Categories Block" module to "displayTopColumn" hook (yep, designer put categories list near (on?) slider). But, by default, there is no possibilities to do this. I don't like that awful Prestashop restrictions, so maybe there is solution for this problem - remove those restrictions?
Thanks.

Removing those restrictions would not resolve anything for a simple reason: if you could hook the module blockcategories to displayTopColumn, this module would not know what to display in this hook because there is no hookDisplayTopColumn() function in it.
However, you can modify the module, and add a function to manage this hook.
To do so, open the file blockcategories.php and add the following:
public function hookDisplayTopColumn($params)
{
// Your code
}
If you want to display here the same content as in the hookLeftColumn hook, you can simply do this:
public function hookDisplayTopColumn($params)
{
return $this->hookLeftColumn($params);
}
You can also create your own function and template by copying, pasting and modifying the code you can find in the function hookLeftColumn() or in the function hookFooter().

How to insert module into product page in prestashop

I am creating a new module in Prestashop 1.6 which displays some data on the products page in the info box. I have created a new hook in the install method of the module like this: $this->registerHook('combinationDescription') and created the hookDisplayCombinationDescription function for assigning some smarty variables and displaying them with a tpl file.
After installing my module the hook is registered into the database so its usable.
Manually I can insert code into the product.tpl file just like: {hook h="hookDisplayCombinationDescription"} and I think it's working, but I would like to make this step automatically when the module gets installed. How can I do that?
My guess would be that to edit the product.tpl file from the install method of the module but it's a bit dirty method for me. Is there some other nice way to do that?
If you made a custom hook you need to insert its execution somewhere manually: into .tpl or into overrided ProductController.php (if it is an action hook). Prestashop can't execute it automatically for it doesn't know where do you want to execute it.
But you can use the default Prestashop 1.6 hooks to make your part of the code hooked and ready after the module installation. For the product page are these:
displayLeftColumnProduct
displayRightColumnProduct
displayProductTab
displayProductTabContent
displayFooterProduct
displayProductButtons
displayProductPriceBlock
actionProductOutOfStock
You can use one of these hooks and position your content with css (or javascript - to any part of the page).
If you make any custom hook then you have to make it executable first.Prestashop can't execute custom hooks automatically.But for displaying some data on product page you can use predefined prestashop hooks.Some are following
displayProductButtons
displayProductTab
To use these hooks, first you have to register hooks in install function like
public function install()
{
if (!parent::install() || !$this->registerHook('displayProductButtons')){
}
}
and in the same file you have to make a function like
public function hookDisplayProductButtons($params)
{
}
Now in that function you can assign some smarty variables which you want to access or show in your tpl file like
public function hookDisplayProductButtons($params)
{
$this->smarty->assign(array(
'product_name' => 'abc'
));
}
Now in your tpl file you can access that
If you want to add new custom hook and execute them when your particular module is active or installed.
Please follow the following steps:
Add you new custom hook code any where you want to perform your action.
Then, you can insert entry for that new custom hook into database at the time of installing module.
Now, your hook will execute as per your need.
Delete the same entry of hook from database at the time of uninstalling module so that hook could not be executed after uninstalling module.
I am not sure for, Is any other solution available to fulfill your need in prestashop?

Prestashop template hook call

I want to call a hook from template like this:
{hook h='displayCustom' mod='customcontent'}
I created a new hook and added method to module like this:
$this->registerHook('displayCustom');
public function hookDisplayCustom($params) {
return $this->display(__FILE__, 'customcontent.tpl');
}
I see that module triggered but there is no output. How can i fix it?
Prestashop 1.6, customcontent.tpl contents simple text 'TEST'.
If smbdy will get in trouble with this.
Possible solution is:
There is a trigger in admin panel that turns off all other modules except native.
The path is: Admin panel -> Configuration -> Performance -> Turn off all non-native modules. It has to be off.

Common php functions in hack

I decided to start a new project to get into hacklang, and after fixing some if the problems I initially ran into transitioning from php habits, I ran into the following errors:
Unbound name: str_replace
Unbound name: empty
Doing some research I found that this is due to using 'legacy' php which isn't typechecked, and will error with //strict.
That's fine and all, empty() was easy enough to replace, however str_replace() is a bit more difficult.
Is there an equivalent function that will work with //strict? Or at least something similar.
I'm aware that I could use //decl but I feel like that defeats the purpose in my case.
Is there at least any way to tell which functions are implemented in hack and which are not in the documentation as I couldn't find one?
For reference (though it isn't too relevant to the question itself), here is the code:
<?hh //strict
class HackMarkdown {
public function parse(string $content) : string {
if($content===null){
throw new RuntimeException('Empty Content');
}
$prepared = $this->prepare($content);
}
private function prepare(string $contentpre) : Vector<string>{
$contentpre = str_replace(array("\r\n","\r"),"\n",$contentpre);
//probably need more in here
$prepared = Vector::fromArray(explode($contentpre,"\n"));
//and here
return $prepared;
}
}
You don't need to change your code at all. You just need to tell the Hack tools about all the inbuilt PHP functions.
The easiest way to do this is to download this folder and put it somewhere in your project. I put it in a hhi folder in the base of my project. The files in there tell Hack about all the inbuilt PHP functions.
Most of them don't have type hints, which can lead to Hack thinking the return type of everything is mixed instead of the actual return, that is actually correct in most cases as, for example, str_replace can return either a string or a bool. However, it does stop the "unbound name" errors, which is the main reason for adding them.

Overriding CDocument OnFileSave()

How do I do this? If you could please kindly include the code for message map and the function itself, that would be greatly appreciated.
EDIT:
More specifically I am wondering how OnFileSave() links to OnSaveDocument(LPCSTR lpszPathName)
How does OnFileSave get lpszPathName?
You don't need to do anything special to override OnSaveDocument(...) it's already a virtual function in CDocument, so your derived class can just declare virtual BOOL OnSaveDocument(LPCTSTR lpszPathName); in it's header, then implement it in the document. Nothing is needed in the message map. OnSaveDocument will be called by the framework as part of OnFileSave which is a handler in the base class for ID_FILE_SAVE. The lpszPathName refers to m_strPathName when called by OnFileSafe, which is set when opening a file or by calling SetPathName. If it's empty when saving, the user is prompted for a file name.
CDocument::OnFileSave is the message handler for the Save menu command. To handle it yourself put this in your document class message map:
ON_COMMAND(ID_FILE_SAVE, OnFileSave)
and add your function:
void CYOURDOCUMENT::OnFileSave()
{
CDocument::OnFileSave();
}
To see everything it does put a breakpoint in your function and start single-stepping.

Declaring function in Blocks in Drupal 6

I am facing an issue in declaring a fucation in block which I have added . I am calling a function by including an file which ia placed in the theme. I have also tried it by placing out of the theme folder. The function is alredy being user in front page. But when I am using the same function in that block. The screen gets blank and nothing displays. some part of my block coding is written below. Please help me.
<?php
global $base_url;
include($_SERVER['DOCUMENT_ROOT']."/travellar/geoiploc.php"); // indluded file
$ip = "203.189.25.0"; // Australia IP test
$country_code = getCountryFromIP($ip, "code");
I've had no problems loading functions from modules into custom blocks, but I've never tried loading one from a theme before. It's not clear to me whether or not theme functions are loaded before the page content is loaded.
You might have to create a custom module or include file to hold the function. Check out the module_load_include() function for how to load a specific include file.
A custom module would be a good approach as it is loaded before the theme layer and can be accessed from almost anywhere in Drupal except other modules with a lower weight than the custom module. It is also likely to come in handy for hooks and other overrides.
However, if you must have it in the theme layer, another option is adding it to template.php of your theme which should make it available within page.tpl.php and such, but not blocks I don't believe.
/sites/all/modules/mymodule/mymodule.info
name = My Module
package = !
description = It is MY module, not yours!
core = 6.x
The package "!" will make this module appear at the top of the modules page
/sites/all/modules/mymodule/mymodule.module
<?php
// Load mymodule.morePHP.inc
module_load_include('inc', 'mymodule', 'mymodule.morePHP');
// A custom function
function mymodule_my_custom_function($args) {
/* do custom stuff here */
return 'output';
}
/sites/all/modules/mymodule/mymodule.morePHP.inc
<?php
// An included custom function
function mymodule_other_custom_stuff() {
}
