Hidden

The hidden field creates a simple hidden input. It's usually used to store custom data that cannot be changed.

Settings

This field doesn't have any specific settings. It only uses common settings.

To store the hidden value, put it in the std setting.

This is a sample field settings array when creating this field with code:

[
    'id'   => 'field_id',
    'type' => 'hidden',
    // Hidden field must have predefined value
    'std'  => 'Hidden value',
],

Data

Although the value is fixed in the code, this field still saves it in the database.

Template usage

To get the field value, use this code

<?php $value = rwmb_meta( 'my_field_id' ) ?>
<p>The hidden value: <?= $value ?>
