If you still maintain a legacy PHP theme, field data is exposed through the $this->view['fields'] structure.

<?php
echo $this->view['fields']['aws_price_calc_1']['id'];
echo $this->view['fields']['aws_price_calc_1']['label_id'];
echo $this->view['fields']['aws_price_calc_1']['label_name'];
echo $this->view['fields']['aws_price_calc_1']['field_id'];
echo $this->view['fields']['aws_price_calc_1']['type'];
echo $this->view['fields']['aws_price_calc_1']['class'];
echo $this->view['fields']['aws_price_calc_1']['html'];
echo $this->view['fields']['aws_price_calc_1']['value'];
?>

Main properties:

• id: numeric field ID
• label_id: unique label element ID
• label_name: translated label text
• field_id: HTML field ID
• type: field type
• class: CSS class applied to the field
• html: rendered HTML for the field widget
• value: current field value

Example of rendering a legacy field widget:

<?php
echo $this->view['fields']['aws_price_calc_1']['html'];
?>

For new 3.x projects, do not start from this legacy API. Use the modern theme options, Preview, scoped CSS, or WordPress hooks instead.
