How to extend frontend user form?

There is a possibility to add additional form input fields in frontend without adding additional logic how to save the field data. This page will describe how to achieve this by using extend user module example.

Preparation

For having additional input field in user form first of all there will be a need to create new column in user table. This can be achieved by using module events which would create a column. In this page an example of database table column called EXTENDUSER_ADDITIONALCONTACTINFO will be used.

Template

The block which will have to be extend is located in template file form/fieldset/user_billing.tpl. To extend it there will be a need to create a template file and describe it in metadata.php file:

'blocks' => array(
    array('template' => 'form/fieldset/user_billing.tpl', 'block'=>'form_user_billing_country', 'file'=>'/views/user.tpl'),
),

/views/user.tpl contents could look like this:

[{$smarty.block.parent}]

<div class="form-group">
    <label class="control-label col-lg-3">Additional contact info</label>
    <div class="col-lg-9">
        <input class="form-control" type="text" maxlength="128"
               name="invadr[oxuser__extenduser_additionalcontactinfo]"
               value="[{$oxcmp_user->oxuser__extenduser_additionalcontactinfo->value}]"
               required=""
        >
    </div>
</div>

Most important thing here is input field with name attribute name="invadr[oxuser__extenduser_additionalcontactinfo]" which says for OXID eShop to try write into table oxuser column EXTENDUSER_ADDITIONALCONTACTINFO provided value.

Modify white listed fields

For security reasons there is an array of “white listed” fields. Only those table columns which has equivalent field in “white list” array can be updated by submitting form and passing parameters via POST request.

There are two classes which contains white listed fields:

• For table oxusers - OxidEsales\EshopCommunity\Application\Model\User\UserUpdatableFields.

• For table oxaddress - OxidEsales\EshopCommunity\Application\Model\User\UserShippingAddressUpdatableFields.

So to add additional field to the white list it’s needed to extend one of those classes. In oxuser table case - OxidEsales\EshopCommunity\Application\Model\User\UserUpdatableFields. Entry in module metadata file would look like this:

'extend' => [
    \OxidEsales\Eshop\Application\Model\User\UserUpdatableFields::class => \OxidEsales\ExtendUser\UserUpdatableFields::class
],

And the contents of file could look like this:

namespace OxidEsales\ExtendUser;
/**
 * @see \OxidEsales\Eshop\Application\Model\User\UserUpdatableFields
 */
class UserUpdatableFields extends UserUpdatableFields_parent
{
    public function getUpdatableFields()
    {
        $updatableFields = parent::getUpdatableFields();
        return array_merge($updatableFields, ['EXTENDUSER_ADDITIONALCONTACTINFO']);
    }
}

In this way into updatable fields array would be added new field - EXTENDUSER_ADDITIONALCONTACTINFO.

So after module activation new form functioning field will appear in the user form.
