Making a simple module with little php experience

[Dani1989]

Hello, 

I am new to the whole PrestaShop ecosystem. I do not know PHP, but i do know JavaScript, NodeJS, React and intermediate Java and C#.

I want to make a very simple module with the following requirements:

Lets say i have a shop that sells cables per rol.

I want the customer to be able to buy either per meter or per complete rol.

I want the module to do the following:

• Take the price per rol
• If customer wants to buy a complete rol, then display price per rol.
• If customer wants to buy per meter, add X% to price per rol and calculate the price per meter including the percentage increase, then display price. 

Would something like that be difficult to implement and are there any security concerns I should be aware of?

Also where should I start? Should I start from the basics of PHP? Are there any resources that would teach me the syntax of PHP given that I already know other languages?

This is not the simplest and easiest module that you could start with

 

Here you can generate a module skeleton: https://validator.prestashop.com/generator

And here you have the doc https://devdocs.prestashop.com/

Yeah, like @joseantgv  that definitely is not simple module to make and not the best to start with.

You can check if there is similar module here

But also for your problem you may try other solution without making a module. Not sure if it would be possible 

but try to make 2 attributes: by roll and by meter. That could be radio buttons. Base product price could be 0 

and then impact on price for "by roll" attribute could be let say $100 for roll of 50m.  And for attribute "by meter" could have

impact for example $100 * 20% / 50m  = $2.4 per m.

@joseantgv @razaro Thanks for your suggestions. I'll see if i can do it without a module at first.
