Validate profile form and use templates for fields Let’s start first with a non-fancy validation method with just if conditionals instead of bringing yet another complicated library. I hope i do not regret it. I wanted to move all the input field to a template because all that gobbledygook with the .input div and repeating the label in the placeholder was starting to annoy me. Now with error messages was even more concerning. I did not know whether the label should be a part of the input fields or something that the template should do. At the end i decided that it makes more sense to be part of the input field because in the error messages i use that same label, thus the template does not have a say in that, and, besides, it was just easier to write the template. The same with the error messages: i’ve seen frameworks that have a map with the field’s id/name to the error slice, but then it would be a bit harder to write the template. I added AddError functions instead of just using append inside the validator function, and have a local variable for whether it all went OK, because i was worried that i would leave out the `ok = false` in some conditions. I had started writing “constructors” functions for InputField and SelectField, but then had to add other methods to change the required field and who knows what else, and in the end it was easier to just construct the field inline.

Allow optional select with empty label This is not yet necessary, but the empty label is because i do not want to select a default tax for products—at least, not without a setting for it. Since i need to add the required attribute now to select, because otherwise the browser would allow sending that empty value, i did not want to do it unconditionally, just in case.

Use a “proper” struct for the login form Similar to the profile form, the login form now parses and validates itself, with the InputField structs that the templates expect. I realized that i was doing more work than necessary when parsing fields fro the profile form because i was repeating the operation and the field name, so now it is a function of InputField. This time i needed extra attributes for the login form. I am not sure that the Go source code needs to know about HTML attributes, but it was the easiest way to pass them to the template.

Handle tax details and new tax forms with structs and validation I implemented the Valuer and Scanner interfaces to InputField and SelectField for better passing values between the database and Go. I had a conflict with the Value name and renamed the struct member to Val. I also had to change the attributes array to be of type template.HTMLAttr or html/template would replace `form="newtax"` attribute to `zgotmplz="newtax"` because it deems it “unsafe”. I do not like having to use template.HTMLAttr when assigning values, but i do not know what else i can do now.
