how to prefill an input field in template using Mojolicious::Plugin::TagHelpers

[fluca1978]

I use Mojolicious::Plugin::TagHelpers to design my form templates, and I've fields like the following one:

        <div class="col">                                                                                 
            %= text_field 'name' => id => 'name', class => 'form-control'                                   
        </div>     

How can I prefill the field with the value of stashed variable $user->name if set? So I would like to inject a value like $user ? $user->name : '' but I cannot find how to instrument the text_field appropriately.

text_field takes the prefilled data from $c->param, so you use $c->param( name => $user->name // '' ); in your controller.

I think this is documented in Mojolicious::Plugin::TagHelpers <https://docs.mojolicious.org/Mojolicious/Plugin/TagHelpers#toc> Description: *Most form helpers can automatically pick up previous input values and will show them as default. You can also use "param" in Mojolicious::Plugin::DefaultHelpers to set them manually and let necessary attributes always be generated automatically.* The example includes this as well: *% param country => 'germany' unless param 'country';* <%= radio_button country => 'germany' %> Germany <%= radio_button country => 'france' %> France <%= radio_button country => 'uk' %> UK

@daleif thanks, sometimes I forgot how easy and consistent Mojolicious is!
@s1037989 thanks, I totally missed such paragraph in the documentation, shame on me.

It took me a while to figure that out as well at the beginning.

Do note though that there is a caveat: There are some terms in param that are used for other things, so some names cannot be used for form variable names.

You seem to be using Bootstrap or similar (I do as well). I've been thinking whether it might be useful to make a version of Mojolicious::Plugin::TagHelpers where certain tags already come with the normal BS classes. And perhaps have two class attributes, what that adds to the default class setting, and one that overwrites (like with content_for and content_with)

Yes, clear.

I'm using bootstrap, and it would be great to have such an integration in Mojolicious, according to me.
