12 my $validator = Mojolicious::Validator->new;
13 my $v = Mojolicious::Validator::Validation->new(validator => $validator);
14 $v->input({foo => 'bar'});
15 $v->required('foo')->in('bar', 'baz');
16 say $v->param('foo');
17
19 Mojolicious::Validator::Validation performs Mojolicious::Validator
20 validation checks.
21
23 Mojolicious::Validator::Validation implements the following attributes.
24
25 csrf_token
26 my $token = $v->csrf_token;
27 $v = $v->csrf_token('fa6a08...');
28
29 CSRF token.
30
31 input
32 my $input = $v->input;
33 $v = $v->input({foo => 'bar', baz => [123, 'yada']});
34
35 Data to be validated.
36
37 output
38 my $output = $v->output;
39 $v = $v->output({foo => 'bar', baz => [123, 'yada']});
40
41 Validated data.
42
43 topic
44 my $topic = $v->topic;
45 $v = $v->topic('foo');
46
47 Name of field currently being validated.
48
49 validator
50 my $v = $v->validator;
51 $v = $v->validator(Mojolicious::Validator->new);
52
53 Mojolicious::Validator object this validation belongs to.
54
56 Mojolicious::Validator::Validation inherits all methods from Mojo::Base
57 and implements the following new ones.
58
59 check
60 $v = $v->check('size', 2, 7);
61
62 Perform validation check on all values of the current "topic", no more
63 checks will be performed on them after the first one failed. All checks
64 from "CHECKS" in Mojolicious::Validator are supported.
65
66 csrf_protect
67 $v = $v->csrf_protect;
68
69 Validate "csrf_token" and protect from cross-site request forgery.
70
71 error
72 my $err = $v->error('foo');
73 $v = $v->error(foo => ['custom_check']);
74 $v = $v->error(foo => [$check, $result, @args]);
75
76 Get or set details for failed validation check, at any given time there
77 can only be one per field.
78
79 # Details about failed validation
80 my ($check, $result, @args) = @{$v->error('foo')};
81
82 # Force validation to fail for a field without performing a check
83 $v->error(foo => ['some_made_up_check_name']);
84
85 every_param
86 my $values = $v->every_param;
87 my $values = $v->every_param('foo');
88
89 Similar to "param", but returns all values sharing the same name as an
90 array reference.
91
92 # Get first value
93 my $first = $v->every_param('foo')->[0];
94
95 failed
96 my $names = $v->failed;
97
98 Return an array reference with all names for values that failed
99 validation.
100
101 # Names of all values that failed
102 say for @{$v->failed};
103
104 has_data
105 my $bool = $v->has_data;
106
107 Check if "input" is available for validation.
108
109 has_error
110 my $bool = $v->has_error;
111 my $bool = $v->has_error('foo');
112
113 Check if validation resulted in errors, defaults to checking all
114 fields.
115
116 is_valid
117 my $bool = $v->is_valid;
118 my $bool = $v->is_valid('foo');
119
120 Check if validation was successful and field has a value, defaults to
121 checking the current "topic".
122
123 optional
124 $v = $v->optional('foo');
125 $v = $v->optional('foo', @filters);
126
127 Change validation "topic" and apply filters. All filters from "FILTERS"
128 in Mojolicious::Validator are supported.
129
130 # Trim value and check size
131 $v->optional('user', 'trim')->size(1, 15);
132
133 param
134 my $value = $v->param;
135 my $value = $v->param('foo');
136
137 Access validated values, defaults to the current "topic". If there are
138 multiple values sharing the same name, and you want to access more than
139 just the last one, you can use "every_param".
140
141 # Get value right away
142 my $user = $v->optional('user')->size(1, 15)->param;
143
144 passed
145 my $names = $v->passed;
146
147 Return an array reference with all names for values that passed
148 validation.
149
150 # Names of all values that passed
151 say for @{$v->passed};
152
153 required
154 $v = $v->required('foo');
155 $v = $v->required('foo', @filters);
156
157 Change validation "topic", apply filters, and make sure a value is
158 present. All filters from "FILTERS" in Mojolicious::Validator are
159 supported.
160
161 # Trim value and check size
162 $v->required('user', 'trim')->size(1, 15);
163
165 In addition to the "ATTRIBUTES" and "METHODS" above, you can also call
166 validation checks provided by "validator" on
167 Mojolicious::Validator::Validation objects, similar to "check".
168
169 # Call validation checks
170 $v->required('foo')->size(2, 5)->like(qr/^[A-Z]/);
171 $v->optional('bar')->equal_to('foo');
172 $v->optional('baz')->in('test', '123');
173
174 # Longer version
175 $v->required('foo')->check('size', 2, 5)->check('like', qr/^[A-Z]/);
