Zen Custom Fields

The plugin converts regular HTML tables, embedded in your page, into arrays of values that you can use in your templates to output the data.
Custom fields can hold text and any HTML code (except for tables). Array of values can be simple index based or more complex key value pairs.
You can embed many tables with values on your page with various data.

Usage

1. Place the table with values you want to use on your page between ‘[zen-fields] … [/zen-fields]’ short-tags
2. In your template use ‘zen_field()’ function to output values from above table

If your would like to use multiple tables with values you should name ech table and use table name as the last parameter of zen_field() function

…

Iteration over values in tables

It is possible to iterate over values from your tables. The variable ‘$zen_fields->tables’ holds the array with values from all the tables on the page.

Escaping output

By default output is not escaped which allows you to use links, images and another HTML content in your custom fields. If you would like to escape the output use ‘zen_field_esc()’ function instead of ‘zen_field()’.

How to use this plugin?

Simply add table to your page between [zen-fileds] short-tags. And use zen_field() function to output value from that table.

e.g. <?php echo zen_field(1) ?> – will output value from second row of your table that contains values only

<?php echo zen_field(1, 2) ?> - output values from 2 dimensional tables

<?php echo zen_field('field name 2') ?> - output value from table with key names defined. Key names should be defined in `<th>` - table header tags.

<?php echo zen_field('field name 2','column 1') ?> - output values from 2 dimensional table with key names defined.

Check ‘Screenshots’ section for more details.

How to use multiple tables?

e.g. <?php echo zen_field('field name 1','column name 2', 'some table name') ?>
