I have a page with 2 forms. Since the id attribute of HTML elements must be unique, I prefixed my ids with login_ and register_. I'm using Request objects to handle those requests : I made a LoginRequest and a RegisterRequest, and set the rules in the rules() method.
However, when printing the errors, I know have a message like :
The login email field is required.
Is there any way I can tell Laravel that even if the id of my input is login_email, I would like him to print email (i.e. without the prefix) ? I know I can return custom messages by implementing the messages() method, however I would like to avoid doing that, since the default messages are good for me, just the value of the :attribute object that makes the error message a bit hard to understand.

In Laravel form validation you can do this: file_description.* to validate each item of an array according to a set of rules. The problem is, the system automatically returns "file_description.1 is required" as an error message if the field is required and not filled in.
More on that here: https://ericlbarnes.com/2015/04/04/laravel-array-validation/
Now, I'm not a complex man, I just want the field to say "File Description 1 is required". I am aware you can set messages but a) my input arrays are dynamically generated by jquery (click to add more type scenario) so I'd have to use a loop like in the above example b) I feel like there must be a better way.
Is there a way to either extend the core validation system to simply return a humanized name for the array field as Laravel does with regular fields, or is there an option I missed in the docs that allows for this? I'd rather not get involved with doing some regex type search to fix this.
I'm using FormRequest validation in my Laravel controller method. I'm validating (beside others) fields 'password' and 'password_confirmation'. The rules are:
$rules['password'] = 'required|string|min:8|required_with:password_confirmation';
$rules['password_confirmation'] = 'min:8|required_with:password|same:password';
(I'm not using 'confirmed', because the validation message is always only on the first field, not on the confirmation one)
When the password confirmation does not match thus the validation fails all data does get returned to the form, including the passwords. Is there some way to exclude them from returning only in case of failed validation - so that the user has to manually input them again? I presume it has to be done somewhere in the custom FormValidation class, probably overriding one of its methods - however, how would I go about it? Just delete it from the returning array?
in the password fields of your register.blade.php, remove the old('password') from the value attribute.
What would be the best way to create validator that checks if model value is unique or not, but it does not return false - it only shows message "the value already exists" (I can still save the model)?
Validators usually don't return boolean values, they add errors for given model attribute(s).
One of the ways (with minimal completions) will be using built-in UniqueValidator and saving without running validation.
At first call $model->validate() to fill model with errors.
You can use $model->validate('fieldName') to validate only needed field.
Then call $model->save(false) or $model->save('fieldName') (for just one field).
This will prevent validation before saving and model values will be saved "as is".
Another way for just saving one attribute without triggering events, etc. will be using updateAttributes after calling validate():
$model->updateAttributes(['fieldName' => 'fieldValue']);
I have a form with a number of fields.
Some of them are userId, userFirstName, userLastName.
When user inputs incorrect userId value then near userId field page must show error message and add this error into validationSummary(this is standart behavior for asp.net mvc unobtrusive validation). If userId is correct then page must remove errors and autopopulate userFirstName and userLastName(This is not standart behavior)
How can i implement this?
Here is what come to my mind:
Remote validation attribute
It has a bad customization in my case. That's why i decide to don't use it.
Add special method for jquery validation plugin ( for example
jQuery.validator.addMethod("userIdValidation", function(value, element) {
//some logic
return something;
}, "Please specify the correct userId"); )
and put there logic for validation and for autopopulate other fields.
In this case i mix validation and other stuff.
3 . Add special method for jquery validation plugin ONLY for validation and add special handler for input change event for autopopulate.
In this case i need to send TWO ajax requests to server for one thing. And ofcourse it is not good too. So what is the right way? I am confused.
Have you thought about using a partial view to display the userFirstName and userLastName?
You can fire an AJAX request that sends the userId, and then returns a partial view of the name fields. Within the controller being called, you can validate the incoming userId, and then grab the name details in one query. If thevalidation fails, you can return the partial view with empty fields.
I've been search for quite a while and haven't been able to find an answer to this.
I am using asp.net MVC 3 with unobtrusive validation. My model is bound with data annotations for simple validation (required fields, regex, etc..). However, I have more complex validation that occurs on the server. I'm doing an ajax post which returns me validation add'l messages that come from my domain model. All I want to do is put those validation messages on the form in the place of the existing ones. I don't want to use partial views since all I've really got are messages coming back and there isn't a need to refresh the whole view. Also, I'm not adding new rules or new inputs to the form so $.validator.unobtrusive.parse won't work. These are just messages I want to put on the form. The $.post call returns a list of message with which field is/was affected and the validation message.
Here's kind of what I'm looking to do
$.post(url, { someData}, function (data) {
for (message in data.Messages) {
$("#form").validate().addMessage(message.Field, message.Text);
}
});
Thanks for your help
Per request, here's a sample of the returning JSON, it's fairly simple.
{"id":0,"messages":["Level":0,"Message":"Style is required","Name":"Style"}],"operationResult":false}
messages is a list of objects that contain the severity level, the property the error belonged to and the error message. I would use the name in the messages object to match where it want on the form.
I had exactly the same requirement, I actually found the following method.
var validator = $("form").validate();
validator.showErrors({field : "Error Message"})
