Foundation Laravel Package
zurb/foundation
Foundation is a responsive front-end framework for building sites and apps on any device. Includes a customizable grid, Sass mixins, JavaScript plugins, and accessibility support, with docs and releases available to help you go from prototype to production.
title: Abide description: Abide is a form validation library that extends the HTML5 validation API with custom validators. sass: scss/forms/_error.scss js: js/foundation.abide.js video: '4bN0qr5pxjs' tags:
- forms
- validation
Abide Demo
These input types create a text field: text, date, datetime, datetime-local, email, month, number, password, search, tel, time, url and week. Note the use of the novalidate attribute to disable any browser validation that could conflict with Abide.

Form Errors
Abide automatically detects Form Errors of an input by their class (.form-error by default, see the formErrorSelector option) when they are siblings of the input or inside the same parent.
When the Form Errors cannot be placed next to its field, like in an Input Group, the relation can be declared with [data-form-error-for] attribute.
<form data-abide novalidate>
<div data-abide-error class="sr-only">
There are some errors in your form.
</div>
<div>
Amount
<div class="input-group">
<span class="input-group-label">$</span>
<input class="input-group-field" id="example3Input" type="number" required pattern="number"/>
</div>
<label class="form-error" data-form-error-for="example3Input">Amount is required.</label>
</div>
<button class="button" type="submit" value="Submit">Submit</button>
</form>
You can specify validator-specific error messages using [data-form-error-on]
attribute, for example:
data-form-error-on="required"data-form-error-on="pattern"data-form-error-on="equalTo"data-form-error-on="your_custom_validator"
<form data-abide novalidate>
<label>Email Required
<input type="text" required pattern="email">
<span class="form-error" data-form-error-on="required">
Yo, you had better fill this out, it's required.
</span>
<span class="form-error" data-form-error-on="pattern">
Invalid Email
</span>
</label>
<button class="button" type="submit" value="Submit">Submit</button>
</form>

Required Radio & Checkbox
If you add required to a radio or checkbox input the whole group gets considered as required. This means at least one of the inputs must be checked.
Checkbox inputs support the additional attribute data-min-required what lets you specify how many checkboxes in the group must be checked (default is one).
<form data-abide novalidate>
<div class="grid-x grid-margin-x align-bottom">
<div class="cell medium-6 large-4">
<fieldset>
<legend>Radio Group</legend>
<input type="radio" name="exampleRadio" id="exampleRadioA" value="A">
<label for="exampleRadioA">A</label>
<input required type="radio" name="exampleRadio" id="exampleRadioB" value="B">
<label for="exampleRadioB">B</label>
<input type="radio" name="exampleRadio" id="exampleRadioC" value="C">
<label for="exampleRadioC">C</label>
</fieldset>
</div>
<div class="cell medium-6 large-4">
<fieldset>
<legend>Checkbox Group</legend>
<input data-min-required="2" type="checkbox" name="exampleCheckbox" id="exampleCheckboxA" value="A">
<label for="exampleCheckboxA">A</label>
<input required type="checkbox" name="exampleCheckbox" id="exampleCheckboxB" value="B">
<label for="exampleCheckboxB">B</label>
<input type="checkbox" name="exampleCheckbox" id="exampleCheckboxC" value="C">
<label for="exampleCheckboxC">C</label>
</fieldset>
</div>
<div class="cell large-4">
<button class="button" type="submit">Submit</button>
</div>
</div>
</form>
Event Listener
Setup event listener after foundation is initialized (especially for formvalid/forminvalid). Easier to chain via document selector.
- valid.zf.abide and invalid.zf.abide are field level events, triggered in validateInput function
- ev.target is the DOM field element,
- elem is jQuery selector for field element
- formvalid.zf.abide and forminvalid.zf.abide are form events, triggered in validateForm function
- ev.target is the DOM form element,
- frm is jQuery selector for form element
$(document)
// field element is invalid
.on("invalid.zf.abide", function(ev,elem) {
console.log("Field id "+ev.target.id+" is invalid");
})
// field element is valid
.on("valid.zf.abide", function(ev,elem) {
console.log("Field name "+elem.attr('name')+" is valid");
})
// form validation failed
.on("forminvalid.zf.abide", function(ev,frm) {
console.log("Form id "+ev.target.id+" is invalid");
})
// form validation passed, form will submit if submit event not returned false
.on("formvalid.zf.abide", function(ev,frm) {
console.log("Form id "+frm.attr('id')+" is valid");
// ajax post form
})
// to prevent form from submitting upon successful validation
.on("submit", function(ev) {
ev.preventDefault();
console.log("Submit for form id "+ev.target.id+" intercepted");
});
// You can bind field or form event selectively
$("#foo").on("invalid.zf.abide", function(ev,el) {
alert("Input field foo is invalid");
});
$("#bar").on("formvalid.zf.abide", function(ev,frm) {
alert("Form is valid, finally!");
// do something perhaps
});
Builtin Patterns and Validators
The following patterns and validators are already built in:
alpha,
alpha_numeric,
card,
color
cvv,
date,
dateISO,
datetime,
day_month_year,
domain,
email,
integer,
month_day_year,
number,
time,
url
Apart from these standard patterns, we have a website pattern too which is basically a combo of both domain and url pattern and we recommend you to use this website pattern for validating websites.
They are defined by regular expressions as you can see below. Note, that the patterns that relate to text such as alpha and alpha_numeric do not consider special characters from other languages. You need to add these special characters yourself to the regular expressions. For instance, for the German language you need to add:
alpha : /^[a-zäöüßA-ZÄÖÜ]+$/,
alpha_numeric : /^[a-zäöüßA-ZÄÖÜ0-9]+$/,
Then you need to customize the builtin patterns as explained in the next section. Otherwise Abide will produce an error if a special character is input in your text field which is validated with pattern="alpha" or pattern="alpha_numeric".
Here are the definitions of the builtin patterns:
alpha : /^[a-zA-Z]+$/,
alpha_numeric : /^[a-zA-Z0-9]+$/,
integer : /^[-+]?\d+$/,
number : /^[-+]?\d*(?:[\.\,]\d+)?$/,
// amex, visa, diners
card : /^(?:4[0-9]{12}(?:[0-9]{3})?|5[1-5][0-9]{14}|6(?:011|5[0-9][0-9])[0-9]{12}|3[47][0-9]{13}|3(?:0[0-5]|[68][0-9])[0-9]{11}|(?:2131|1800|35\d{3})\d{11})$/,
cvv : /^([0-9]){3,4}$/,
// https://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#valid-e-mail-address
email : /^[a-zA-Z0-9.!#$%&'*+\/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)+$/,

website: {
test: (text) => {
return Abide.defaults.patterns['domain'].test(text) || Abide.defaults.patterns['url'].test(text);
}
}
Adding Custom Pattern and Validator
- Override builtin patterns and validators before foundation is initialized
- Add new patterns and validators before or after foundation is initialized
function myCustomValidator(
$el, /* jQuery element to validate */
required, /* is the element required according to the `[required]` attribute */
parent /* parent of the jQuery element `$el` */
) {
if (!required) return true;
var from = $('#'+$el.attr('data-greater-than')).val(),
to = $el.val();
return (parseInt(to) > parseInt(from));
};
// Set default options
Foundation.Abide.defaults.patterns['dashes_only'] = /^[0-9-]*$/;
Foundation.Abide.defaults.validators['greater_than'] = myCustomValidator;
// Initialize Foundation
$(document).foundation();
<input id="phone" type="text" pattern="dashes_only" required >
<input id="min" type="number" required >
<input id="max" type="number" data-validator="greater_than" data-greater-than="min" required>
jQuery Conflict
When creating a type submit button, make sure to avoid using name="submit" otherwise your form won't submit. This is due to jQuery limitations (see Additional Notes).
Accessibility
By default, Abide will add some accessibility attributes to your form elements. It is highly recommended to keep this option active as it improve the usability of your forms for disabled people. Lean more about Accessibility in Foundation.
However, if you think the attributes added by Abide are not correct, you can disable it by setting a11yAttributes (or [data-a11y-attributes]) to false.
