In my customer edit form, for telephone phone, required field validation is not working when I leave the telephone field blank. The required validation works for every field except for the telephone field.

When I save the form without telephone field, after the backend call it gives me a notification message " telephone" is required. Enter and try again.

enter image description here

This is code for password field in my form

<div class="field telephone required">
<label for="telephone" class="label">
        Phone Number 
<div class="control">
    <input type="text" name="telephone" id="telephone" value="" title="Phone Number" class="input-text " sr-only="INPUT" for="INPUT" aria-required="true">

I even checked eav_attribute table. It has is_required=1 for attribute_code='telephone'

I don't want notification, it should be like other fields inline validation.

    try adding the required-entry class to the input.

  • @Marius Thanks, looks like the vendor code was faulty, they were adding validation class by using fax $_validationClass = $block->escapeHtmlAttr( $this->helper('Magento\Customer\Helper\Address') ->getAttributeValidationClass('fax') );

You just need to add required-entry class in the input field as:

<input type="text" name="telephone" id="telephone" value="" title="Phone Number" class="input-text required-entry" sr-only="INPUT" for="INPUT" aria-required="true">

Its working fine for me.


looks like the vendor code was faulty, They were adding _validationClass by using getAttributeValidationClass of fax


<div class="control">
        $_validationClass = $block->escapeHtmlAttr(
    <input type="text"
           value="<?= $block->escapeHtmlAttr($block->getTelephone()) ?>"
           title="<?= $block->escapeHtmlAttr(__('Phone Number')) ?>"
           class="input-text <?= $_validationClass ?: '' ?>"

As required-entry class is missing so, Just change it to ->getAttributeValidationClass('fax') to ->getAttributeValidationClass('telephone') and it will work.

  • I clearly mentioned, that is_required is 1 for attribute_code='telephone' and you just reiterate same thing using admin panel, solution was i was missing required-entry class,
