I use express-validator to check my post fields. My Problem is I want to make some fields required only if other fields have a specific values. eg:
if person_organisation is true:
person_organisation_name must be required
if person_organisation is false:
person_first_name must be required
Is there any way to put this rules in Validation Schema??
Create custom validation:
app.use(expressValidator({
customValidators: {
checkPersonName: function(name, isPerson) {
return isPerson === true ? name != '' : true;
},
checkOrganisationName: function(name, isPerson) {
return isPerson === false ? name != '' : true;
}
}
}));
and use:
app.post('/registration', function(req, res) {
req.checkBody(
'person_first_name', 'Please provide Your first name'
).checkPersonName(req.body.person_organisation);
req.checkBody(
'person_organisation_name', 'Please provide valid organisation name'
).checkOrganisationName(req.body.person_organisation);
req.getValidationResult().then(function(result) {
if (!result.isEmpty()) {
res.status(400).send({result: result.array()});
return;
}
res.json(); // when success do something
});
});
