Common Rule for Multiple Input Fields pattern in Laravel - laravel

Question

I want to create a common rule for multiple Inpute fields with the name pattern "name_*".
e.g.
I have multiple input fields with the following names:
name
name_fruit
name_animal
name_people
name_region
name_language
description
keywords
image
And I want fields with pattern name, name_* should be 'required|min:3|max:120' Validator.
Currently, I am using the following rule but it wonly works for the first input field name
$rules = array(
'name*' => 'required|min:3|max:120',
);
Is there any way using asterisk or regex or other method through which I can?

Answer 1

You're better off just manually returning a rule array with every single one of those keys. It's easier to read.
public function rules(): array
{
return [
'name' => 'required|min:3|max:120',
'name_fruit' => 'required|min:3|max:120',
'name_animal' => 'required|min:3|max:120',
'name_people' => 'required|min:3|max:120',
'name_region' => 'required|min:3|max:120',
'name_language' => 'required|min:3|max:120',
'description' => '...',
'keywords' => '...',
'image' => '...',
];
}
Of course, that doesn't mean you can't do what you want. But there is no built in wildcard like that. You'd have to write some extra logic.
public function rules(): array
{
$name_fields = ['name', 'name_fruit', 'name_animal', 'name_people', 'name_region', 'name_language'];
$rules = [];
foreach ($name_fields as $name_field) {
$rules[$name_field] = 'required|min:3|max:120';
}
return $rules + [
'description' => '...',
'keywords' => '...',
'image' => '...',
];
}
Another option is to use array validation. For this to work, you'll need to change the name attribute of your inputs.
From name to name_fields[name]
From name_fruit to name_fields[fruit]
From name_animal to name_fields[animal]
From name_people to name_fields[people]
From name_region to name_fields[region]
From name_language to name_fields[language]
public function rules(): array
{
return [
'name_fields' => 'required|array',
'name_fields.*' => 'required|min:3|max:120',
'description' => '...',
'keywords' => '...',
'image' => '...',
];
}
But this also means there's nothing validating against someone passing in an unkonwn field like say.... name[company] to give an example.
