There are 3 different ways to use form validation in magento 2
To enable javascript validation use following code in your template
<form class="form" id="custom-form" method="post" autocomplete="off">
<fieldset class="fieldset">
<legend class="legend"><span><?php echo __('Personal Information') ?></span></legend><br>
<div class="field required">
<label for="email_address" class="label"><span><?php echo __('Email') ?></span></label>
<div class="control">
<input type="email" name="email" id="email_address" value="" title="<?php echo __('Email') ?>" class="input-text" data-validate="{required:true, 'validate-email':true}">
</div>
</div>
</fieldset>
<div class="actions-toolbar">
<div class="primary">
<button type="submit" class="action submit primary" title="<?php echo __('Submit') ?>"><span><?php echo __('Submit') ?></span></button>
</div>
</div>
</form>
1
<script type="text/x-magento-init">
{
"#custom-form": {
"validation": {}
}
}
</script>
2
<form data-mage-init='{"validation": {}}' class="form" id="custom-form" method="post" autocomplete="off">
3
<script type="text/javascript">
require([
'jquery',
'mage/mage'
], function($){
var dataForm = $('#custom-form');
dataForm.mage('validation', {});
});
</script>
*custom-form is form id you can replace it with your form id

You can add class for validation in Magento 2. See example bellow. There is almost 72 rules (validation class) you can use:
$fieldset->addField(
'email_from',
'text',
['name' => 'email_from', 'label' => __('Email From'), 'title' => __('Email From'), 'required' => true, 'class' => 'validate-email']
);
See blog for list of available rules for more info:
Here is list of validations classes rules supported by magento 2. You just need to add css class for the rule to apply.
min_text_length max_text_length max-words min-words range-words letters-with-basic-punc alphanumeric letters-only no-whitespace zip-range integer vinUS dateITA dateNL time time12h phoneUS phoneUK mobileUK stripped-min-length email2 url2 credit-card-types ipv4 ipv6 pattern validate-no-html-tags validate-select validate-no-empty validate-alphanum-with-spaces validate-data validate-street validate-phoneStrict validate-phoneLax validate-fax validate-email validate-emailSender validate-password validate-admin-password validate-url validate-clean-url validate-xml-identifier validate-ssn validate-zip-us validate-date-au validate-currency-dollar validate-not-negative-number validate-zero-or-greater validate-greater-than-zero validate-css-length validate-number validate-number-range validate-digits validate-digits-range validate-range validate-alpha validate-code validate-alphanum validate-date validate-identifier validate-zip-international validate-state less-than-equals-to greater-than-equals-to validate-emails validate-cc-number validate-cc-ukss required-entry checked not-negative-amount validate-per-page-value-list validate-new-password validate-item-quantity equalTo

In UI components it can be used by following sample config (Magento v2.2.0):
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
<fieldset name="general">
<field name="priority" sortOrder="1000" formElement="input">
<settings>
<validation>
<rule name="not-negative-amount" xsi:type="boolean">true</rule>
</validation>
[...]
</settings>
</field>
</fieldset>
</form>
See more examples in file:
vendor/magento/module-cms/view/adminhtml/ui_component/cms_page_form.xml

How can i use it in my custom form? If i use like this <input type="text" name="primary_contact" data-validate="{'validate-phoneStrict':true}" class="valid"> it not working. Feb 18, 2020 at 9:47
If you take reference of /customer/account/create page, you can see the following piece of code underneath the form:
<script>
require([
'jquery',
'mage/mage'
], function($){
var dataForm = $('#form-validate');
var ignore = null;
dataForm.mage('validation', {
ignore: ignore ? ':hidden:not(' + ignore + ')' : ':hidden'
}).find('input:text').attr('autocomplete', 'off');
});
</script>
And if you check at form's input attributes, you can see Magento 1 like class attribute values along with new data-validate attribute.
This can be the basis to step up.

Thx for the answer. I found the new attribute data-validate too, but it's interesting what validations are available. In my case I want to validate a Checkbox and a set of RadioButton– ClassMPDec 28, 2015 at 10:13

I want to apply server side validation in magento 2 can you pls share me any link or doc. Feb 20, 2017 at 10:08
When use UI components to make form, we could use the validation like below, it works in Magento 2.1.x, I doesn't test it in other version yet.
<field name="priority">
<argument name="data" xsi:type="array">
<item name="config" xsi:type="array">
<item name="dataType" xsi:type="string">text</item>
<item name="label" xsi:type="string" translate="true">Priority</item>
<item name="formElement" xsi:type="string">input</item>
<item name="source" xsi:type="string">module_name</item>
<item name="dataScope" xsi:type="string">priority</item>
<item name="validation" xsi:type="array">
<item name="required-entry" xsi:type="boolean">true</item>
<item name="validate-integer" xsi:type="boolean">true</item>
</item>
</item>
</argument>
</field>
Notice the validation item, in it we could add validation rules, like required-entry, validate-integer etc.
<item name="validation" xsi:type="array">
<item name="required-entry" xsi:type="boolean">true</item>
<item name="validate-integer" xsi:type="boolean">true</item>
<item name="validation_rule_name" xsi:type="boolean">true</item>
...
</item>
All validation rules you could find in file vendor/magento/module-ui/view/base/web/js/lib/validation/rules.js, like validate-date, validate-emails etc.
I have same requirement for Magento2 Form Validation and i did this code
First we will setup a test form
<!-- form tag -->
<form class="form" id="custom-form-id" method="post" autocomplete="off">
<fieldset class="fieldset">
<legend class="legend"><span><?php echo __('User Personal Information') ?></span></legend><br>
<div class="field required">
<!-- form field -->
<label for="email_address" class="label"><span><?php echo __('Email') ?></span></label>
<div class="control">
<input type="email" name="email" id="email_address" value="" title="<?php echo __('Email') ?>" class="input-text" data-validate="{required:true, 'validate-email':true}">
</div>
</div>
</fieldset>
<!-- submit button -->
<div class="actions-toolbar">
<div class="primary">
<button type="submit" class="action submit primary" title="<?php echo __('Submit') ?>"><span><?php echo __('Submit') ?></span></button>
</div>
</div>
</form>
To enable javascript validation for Magento2 Form Validation
<!-- enable javascript validation for custom-form-id -->
<script type="text/x-magento-init">
{
"#custom-form-id": {
"validation": {}
}
}
</script>
Reference :: http://www.onlinecode.org/magento2-form-validation-example/
"no-whitespace" option does not work correctly (at least on Magento 2.1). It triggers an error message on any type of "space" character. Values "test me" and " test me " will return the same error.
