Cannot add custom field to Customer

[tempnull]

Hello, i'm new to Prestashop and want to add a custom field 'Phone Number' into Customer module

I found a tutorial and follow it, but it didn't work

https://devdocs.prestashop.com/1.7/development/components/grid/tutorials/modify-grid-in-module/

 

then, i start from the beginning, try Hook in the doc, and it failed again 

https://devdocs.prestashop.com/1.7/development/components/grid/tutorials/modify-grid-in-module/

 

after some researches, i found that the hook function should be registered first

https://devdocs.prestashop.com/1.7/modules/sample-modules/grid-and-identifiable-object-form-hooks-usage/

 

so, which file contains the Install() function i can register my hook? it will work after registered in install?

do i need to call the hook somewhere to trigger it?

thanks!

How to register hook

First, create a hook function in your main .php file of your module. Like this:

public function hookyour_hook_nameHook() {
	dump("it works");
}

Next step, registration of the hook:

1. Programmatically:

During the installation ( function install() ) you have next line:

return parent::install() &&
            $this->registerHook('your_custom_hook_name');

actually, you can register hook anywhere you want with next line:

$this->registerHook('your_custom_hook_name');

2. In the BO of prestashop (I prefer this one):

Go to Design->Positions->Transplant a module (top-right corner)->"choose_your_module"->"choose hook you created" ->Save

 

P.S. the hook "triggers" by itself, you don't need to call it somewhere

P.S2. You can fast create a module here, than follow the instructions I described to you above.
