Validating Exact Values in Laravel Inputs
In Laravel's validation system, you can enforce strict matching of input values against specified exact values. This can be useful when you need to ensure that users input specific predefined words or phrases.
Validation Option 1: 'in' Rule
The 'in' validation rule allows you to define a comma-separated list of acceptable values. For instance, to validate that the 'field' input must be "hello," you would use the following rule:
$rules = [ 'field' => 'in:hello', ];
Validation Option 2: Regular Expression Rule
Alternatively, you can use a regular expression to validate exact values. To match a specific word, you can use the following regular expression:
$rules = [ 'field' => 'regex:^hello$', ];
In this case, the ^ and $ delimiters ensure that the entire input matches "hello" exactly. Note that you may need to adjust the flag delimiters depending on your regex engine.
