Overview
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 field settings.
To store the hidden value, put it in the std
setting.
Sample code
array(
'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 post meta.
Template usage
To get the field value, use this code
$value = rwmb_meta( $field_id );
echo $value;
