Settings
Improve it on GithubSettings structure
There are three levels of settings which are form, field, and validators.
The BootstrapValidator plugin can be called as following:
$(formSelector).bootstrapValidator({
... Form settings go here ...
fields: {
specificFieldName: {
... Field settings go here ...
validators: {
specificValidatorName: {
... common validator settings go here ...
... specific validator settings ...
}
}
}
}
});
Most of settings can be set via HTML 5 attributes prefixed with data-bv
.
For example, the following call:
$(formSelector).bootstrapValidator({
excluded: [':disabled', ':hidden', ':not(:visible)'],
feedbackIcons: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
live: 'enabled',
message: 'This value is not valid',
submitButtons: 'button[type="submit"]',
trigger: null,
fields: ...
});
is equivalent with the one below:
<form data-bv-message="This value is not valid"
data-bv-feedbackicons-valid="glyphicon glyphicon-ok"
data-bv-feedbackicons-invalid="glyphicon glyphicon-remove"
data-bv-feedbackicons-validating="glyphicon glyphicon-refresh"
data-bv-submitbuttons='button[type="submit"]'
data-bv-live="enabled">
...
</form>
$(document).ready(function() {
$(formSelector).bootstrapValidator({
fields: ...
});
});
In the next sections, you will see the full list of options for each level.
Examples

autoFocus: Boolean
Indicate the first invalid field will be focused on automatically. It is true
, by default.
You also can set this option for particular field.
container: String
Indicate where the error messages are shown.
Value | Description |
---|---|
CSS selector | All error messages are placed in element defined by this CSS selector |
tooltip |
Error messages of each field are placed inside a Bootstrap tooltip. |
popover |
Error messages of each field are placed inside a Bootstrap popover. |
This option can be overridden by particular field.
Examples
The following form uses Bootstrap tooltip to show the error message.
<form id="containerForm" class="form-horizontal">
<div class="form-group">
<label class="col-sm-3 control-label">Full name</label>
<div class="col-sm-4">
<input type="text" class="form-control" name="firstName" placeholder="First name" />
</div>
<div class="col-sm-4">
<input type="text" class="form-control" name="lastName" placeholder="Last name" />
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label">Phone number</label>
<div class="col-sm-5">
<input type="text" class="form-control" name="phone" />
</div>
</div>
<div class="form-group">
<div class="col-sm-9 col-sm-offset-3">
<button type="submit" class="btn btn-default">Validate</button>
</div>
</div>
</form>
$(document).ready(function() {
$('#containerForm').bootstrapValidator({
container: 'tooltip',
feedbackIcons: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
fields: {
firstName: {
validators: {
notEmpty: {
message: 'The first name is required'
}
}
},
lastName: {
validators: {
notEmpty: {
message: 'The last name is required'
}
}
},
phone: {
validators: {
digits: {
message: 'The phone number can contain digits only'
},
notEmpty: {
message: 'The phone number is required'
}
}
}
}
});
});
excluded: Boolean
Indicate fields which won't be validated.
By default, the plugin will not validate the following kind of fields:
- disabled
- hidden
- invisible
The setting consists of jQuery filters. Accept 3 formats:
Format | Description |
---|---|
String |
Filters are separated by a comma. For example:
|
Array of strings |
Each element is a filter. For example:
|
Array of strings and callback functions |
The callback function has format as below:
For example:
|
It is also possible to excluded particular field.
The excluded
option is usually used when we need to validate the field generated by other UI plugin.
For an usage, you can take a look at compatibility examples.
feedbackIcons: Object
Indicate valid/invalid/validating icons based on the field validity.
It supports Glyphicons (included in Bootstrap):
feedbackIcons: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
}
and FontAwesome icons (don't forget to insert FontAwesome CSS in your head
):
feedbackIcons: {
valid: 'fa fa-check',
invalid: 'fa fa-times',
validating: 'fa fa-refresh'
}
By default, these icons are not set. You also can enabled or disable feedback icon for particular field.
Using with Bootswatch
Some BootsWatch themes override some CSS styles causing feedback icon invisible to your eyes. For instance, the Flatly theme set the feedback icon color to #FFF
.
To fix this, you can simply add some CSS to your head
, right before the BootsWatch theme CSS, to reset the feedback icons color:
<link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootswatch/3.1.1/flatly/bootstrap.min.css">
<style type="text/css">
.has-error .form-control-feedback {
color: #E74C3C;
}
.has-success .form-control-feedback {
color: #18BCA0;
}
</style>
Example
group: String
CSS selector indicates the parent element of field. By default, it is .form-group
.
Following Bootstrap form structure, each field and its label are wrapped inside .form-group
element.
This option might be used in the following cases:
- The form uses a custom CSS class for each group
- Each group consist of more than one field
You also can specify the group for particular field.
Example
In the following form, each field is placed inside a cell of table. The error messages are placed inside a tooltip.

Live validating mode. Can be one of three values:
Value | Description |
---|---|
enabled default |
The plugin validates fields as soon as they are changed |
disabled |
Disable the live validating. The error messages are only shown after the form is submitted |
submitted |
The live validating is enabled after the form is submitted |
message: String
The default error message for all fields. You can specify the error message for any fields.
submitButtons: String
The submit buttons selector. These buttons will be disabled when the form input are invalid.
threshold: Number
The field will not be live validated if its length is less than this number of characters. You also can set this option for particular field.
trigger: String
The event which is fired to validating all fields when the live validating mode is enabled. If you need multiple events are fired, then separate them by a space.
It's also possible to set trigger option for each field. Look at the field trigger section.
verbose: Boolean
Whether to be verbose when validating a field or not.
Value | Description |
---|---|
true | When a field has multiple validators, all of them will be checked respectively. If errors occur in multiple validators, all of them will be displayed to the user |
false | when a field has multiple validators, validation for this field will be terminated upon the first encountered error. Thus, only the very first error message related to this field will be displayed to the user |
It's also possible to set verbose option for each field. Look at the field verbose section.

The default error message for the field.
selector: String
The CSS selector to indicate the field. It is used in case that it's not possible to use the name
attribute for the field.
Example
Instead of using the name
attribute, the following form uses the selector
option to define the fields:
<form id="paymentForm" class="form-horizontal">

var year = validator.getFieldElements('expYear').val(),
currentMonth = new Date().getMonth() + 1,
currentYear = new Date().getFullYear();
if (value < 0 || value > 12) {
return false;
}
if (year == '') {
return true;
}
year = parseInt(year, 10);
if (year > currentYear || (year == currentYear && value > currentMonth)) {
validator.updateStatus('expYear', 'VALID');
return true;

currentYear = new Date().getFullYear();
if (value < currentYear || value > currentYear + 100) {
return false;
}
if (month == '') {

message: 'The CVV number is required'
},
cvv: {
message: 'The value is not a valid CVV',
creditCardField: 'ccNumber'
}
}

}
});
});
As you see, the field can be defined by a ID (#ccNumber
), class (.cvvNumber
) or attribute ([data-stripe="exp-month"]
) selector.
threshold: Number
Do not live validate field until the length of field value exceed this number.

});
trigger: String
The field events (separated by a space) which are fired when the live validating mode is enabled.
For example, trigger="focus blur"
means that the field will be validated when user focus on or leave the focus off the field.
Example
In the following form, the Title field will be validated while user type any character (trigger="keyup"
). The Summary field will be validated when user lose the focus (trigger="blur"
).
<form id="triggerForm" method="post" class="form-horizontal">
<div class="form-group">
<label class="col-sm-3 control-label">Title</label>

}
});
});
verbose: Boolean
Whether to be verbose when validating a field or not.
Look at the form verbose section to see the possible value for the verbose option.
Validator settings
The following table shows the common settings for validators (when using it, replace {validatorname}
with the validator name). For specific settings of each validator, please look at its documentation.
Option | Equivalent HTML attribute |
---|---|
enabled |
data-bv-{validatorname} |
message |
data-bv-{validatorname}-message |
enabled: Boolean
Indicate the validator is enabled or disabled. It is true
, by default.
Look at the field's enabled option if you want to enable/disable all validators.
The table below shows three equivalent ways to enable or disable given validator:
Usage | Example |
---|---|
HTML 5 attribute |
|
Plugin option |
|
enableFieldValidators() |
|
Example
<form id="validatorEnabledForm" class="form-horizontal">
<div class="form-group">
<label class="col-sm-3 control-label">Full name</label>
<div class="col-sm-5">
<input type="text" class="form-control" name="fullName" />
</div>
</div>
<div class="form-group">
<div class="col-sm-5 col-sm-offset-3">
<button type="submit" class="btn btn-default">Validate</button>
</div>
</div>
</form>
$(document).ready(function() {
$('#validatorEnabledForm').bootstrapValidator({
feedbackIcons: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
fields: {
fullName: {
validators: {
notEmpty: {
// enabled is true, by default
message: 'The full name is required and cannot be empty'
},
stringLength: {
enabled: true,
min: 8,
max: 40,
message: 'The full name must be more than 8 and less than 40 characters long'
},
regexp: {
enabled: false,
regexp: /^[a-zA-Z\s]+$/,
message: 'The full name can only consist of alphabetical, number, and space'
}
}
}
}
});
});
message: String
The error message of validator for field.
Dynamic option
Some validators have option which its value could be change dynamically.
For example, the zipCode validator has the country
option that can be changed dynamically a select element.
The dynamic option can be determined by:
- A string
- Name of field which defines the value
- Name of function which returns the value
- A function returns the value
In the third and fourth cases, the callback function must follow the format:
function(value, validator, $field) {
// value is the value of field
// validator is the BootstrapValidator instance
// $field is the jQuery element representing field element
}
Supported validators
Below is the list of validators supporting dynamic option. Refer to specific validator document to see the full list of options.
Validator | Dynamic option |
---|---|
between validator | min , max |
choice validator | min , max |
greaterThan validator | value |
iban validator | country |
id validator | country |
lessThan validator | value |
phone validator | country |
stringLength validator | min , max |
vat validator | country |
zipCode validator | country |
To illustrate how powerful this concept is, take a look at the following example.
Assume that your form uses zipCode validator to validate a zipcode. The next sections show you how to use four ways above to define option value.
You can use the following sample zipcodes for testing:
Country | Valid Zipcode | Invalid Zipcode |
---|---|---|
United States | 12345 | 123 |
Italy | IT-12345 | 123 |
Using string as usual
It's easy for you if the country code option is set initially and can't be changed:
$(document).ready(function() {
$('#zipcodeForm').bootstrapValidator({
fields: {
code: {
validators: {
zipCode: {
country: 'US',
message: 'The value is not valid zipcode'
}
}
}
}
});
});

What happen if you want the country to be changeable, for example, by a select element. With the dynamic option concept, it can be done easily by setting the country
option as:
Using name of element defining the option value
<!-- The element for choosing a country -->
<select class="form-control" name="countrySelectBox">
<option value="US">United States</option>
<option value="CA">Canada</option>
<option value="DK">Denmark</option>
<option value="IT">Italy</option>
<option value="NL">Netherlands</option>
<option value="SE">Sweden</option>
<option value="GB">United Kingdom</option>
</select>
$(document).ready(function() {
$('#zipcodeElementForm').bootstrapValidator({
fields: {
code: {
validators: {
zipCode: {
country: 'countrySelectBox',
message: 'The value is not valid zipcode'
}
}
}
}
});
});

$(document).ready(function() {

}
}
})
.on('change', '[name="countrySelectBox"]', function() {
// Revalidate the zipcode after changing the country
$('#zipcodeElementForm').bootstrapValidator('revalidateField', 'code');

});
Dynamic message
Looking back to the zipcode example above, you will realize that the message is static:
<!-- The element for choosing a country -->
<select class="form-control" name="countrySelectBox">
<option value="US">United States</option>
<option value="CA">Canada</option>
<option value="DK">Denmark</option>
<option value="IT">Italy</option>
<option value="NL">Netherlands</option>
<option value="SE">Sweden</option>
<option value="GB">United Kingdom</option>
</select>
$(document).ready(function() {
$('#dynamicMessageForm').bootstrapValidator({
fields: {
code: {
validators: {
zipCode: {
country: 'countrySelectBox',
message: 'The value is not valid zipcode'
}
}
}
}
});
});
As you see, the message is always The value is not valid zipcode
and does not change nomatter what the country is.
Fortunately, it is easy to convert this message to a dynamic one. Just use %s
characters in the message and they will be replaced with the country you choose:
$(document).ready(function() {
$('#dynamicMessageForm').bootstrapValidator({
fields: {
code: {
validators: {
zipCode: {
country: 'countrySelectBox',
// %s will be replaced with "US zipcode", "Italian postal code", and so on
// when you choose the country as US, IT, etc.
message: 'The value is not valid %s'
}
}
}
}
});
});
<form id="dynamicMessageForm" class="form-horizontal">
<div class="form-group">
<label class="col-sm-3 control-label">Country:</label>
<div class="col-sm-5">
<select class="form-control" name="countrySelectBox">
<option value="US">United States</option>
<option value="CA">Canada</option>
<option value="DK">Denmark</option>
<option value="IT">Italy</option>
<option value="NL">Netherlands</option>
<option value="SE">Sweden</option>
<option value="GB">United Kingdom</option>
</select>
</div>
</div>
<div class="form-group">
<label class="col-sm-3 control-label">Zipcode</label>
<div class="col-sm-5">
<input type="text" class="form-control" name="code" />
</div>
</div>
</form>
$(document).ready(function() {
$('#dynamicMessageForm')
.bootstrapValidator({
feedbackIcons: {
valid: 'glyphicon glyphicon-ok',
invalid: 'glyphicon glyphicon-remove',
validating: 'glyphicon glyphicon-refresh'
},
fields: {
code: {
validators: {
zipCode: {
country: 'countrySelectBox',
message: 'The value is not valid %s'
}
}
}
}
})
.on('change', '[name="countrySelectBox"]', function() {
// Revalidate the zipcode after changing the country
$('#dynamicMessageForm').bootstrapValidator('revalidateField', 'code');
});
});
Below is the list of validators supporting dynamic message:
Validator | Example |
---|---|
between validator |
|
choice validator |
|
greaterThan validator |
|
iban validator |
|
id validator |
|
lessThan validator |
|
phone validator |
|
stringLength validator |
|
vat validator |
|
zipCode validator |
|
callback validator |
|
remote validator |
The backend returns a JSON string that consists of
|
Your own validator |
|
Turning off dynamic message
To turn off dynamic message:
- Don't use
%s
characters in the message - Don't include the
message
in the result returned by callback, remote validator, or your own validator.
Validator | Example |
---|---|
between validator |
|
callback validator |
|
remote validator |
The backend returns a JSON string that consists of
|
Your own validator |
|
Events
Similar to the settings, there are also events for form, field and validator. Each event can be set by one of three ways:
- Listening to event using jQuery
on(eventName, callback)
- Using option
- Using HTML 5 attributes
Form events
Event | Description |
---|---|
init.form.bv |
Triggered after the form is initialized by the plugin |
error.form.bv |
Triggered when the form is invalid |
success.form.bv |
Triggered when the form is valid |
added.field.bv |
Triggered after adding dynamic field |
removed.field.bv |
Triggered after removing given field |
Usage | Example |
---|---|
Listening to event |
|
Using option |
