i'm new in node and express. i'm trying to make a register page using connect-flash for validation and using ejs template engine . everything is working correct but nothing displayed in my alert box. here is my registerController.js :
showRegisterForm(req, res) {
res.render("auth/register", { messages: req.flash("errors"), recaptcha: this.recaptcha.render() });
}
registerProccess(req, res, next) {
this.validationData(req)
.then(result => {
if(result){res.json('register Proccess')}
else{res.redirect(req.url)};
})
};
validationData(req) {
req.checkBody("name", "name cant be empty").notEmpty();
req.checkBody("name", "name must be more than 2 characters").isLength({ min: 2 });
req.checkBody("password", "password must be more than 8 characters").isLength({ min: 8 });
req.checkBody("password", "password field cant be empty").notEmpty();
req.checkBody("email", "Email is not valid").isEmail();
return req
.getValidationResult()
.then(result => {
const errors = result.array();
const messages = [];
errors.forEach((err) => messages.push(err.msg));
if (errors.length == 0) {
return true;
} else {
req.flash("errors", messages);
return false;
}
})
.catch((err) => console.log(err));
}
register(req, res, next) {
passport.authenticate('local.register', {
successRedirect : '/',
failureRedirect : '/register',
failureFlash : true
})(req, res, next)
}
}
module.exports = new registerController();
and this is my ejs :
<% if(messages.length > 0) { %>
<div class="alert alert-danger alert-dismissible">
<button type="button" class="close" data-dismiss="alert" aria-label="Close">
<span>×</span>
</button>
<% messages.forEach(error => { %>
<%= error %><br>
<% }) %>
</div>
<% } %>
the problem is displaying errors and my code is working correct but nothing displayed in alert section .
