FAQ

How to output the table html?

To render the table fields data as an html table in one of your template files (page.php, single.php) you can start with the following basic code example:

$table = get_field( 'your_table_field_name' );

if ( ! empty ( $table ) ) {

    echo '<table border="0">';

        if ( ! empty( $table['caption'] ) ) {

            echo '<caption>' . $table['caption'] . '</caption>';
        }

        if ( ! empty( $table['header'] ) ) {

            echo '<thead>';

                echo '<tr>';

                    foreach ( $table['header'] as $th ) {

                        echo '<th>';
                            echo $th['c'];
                        echo '</th>';
                    }

                echo '</tr>';

            echo '</thead>';
        }

        echo '<tbody>';

            foreach ( $table['body'] as $tr ) {

                echo '<tr>';

                    foreach ( $tr as $td ) {

                        echo '<td>';
                            echo $td['c'];
                        echo '</td>';
                    }

                echo '</tr>';
            }

        echo '</tbody>';

    echo '</table>';
}
Table field returns no data on get_field()?

If the table has only one empty cell, then get_field() returns FALSE. get_field() returns NULL when a field is not stored in the database. That happens when a page is copied but not their fields content. You can check both with empty()

$table = get_field( 'your_table_field_name' );

if ( ! empty( $table ) ) {
    // $table is not FALSE and not NULL.
    // Field exists in database and has content.
}
How to handle line breaks?

This is about displaying line breaks in the admin tables and getting line breaks as <br> when outputting the tables HTML.

Converting Line Breaks for HTML Output

To convert line breaks to <br> in tables HTML output the PHP function nl2br() can be used:

For line breaks in table header cells replace…

echo $th['c'];

with…

echo nl2br( $th['c'] );

For line breaks in table body cells replace…

echo $td['c'];

with…

echo nl2br( $td['c'] );

Displaying Line Breaks in Editing Tables

To display natural line breaks in the editing tables in the admin area, add the following styles to the admin area.

.acf-table-header-cont,
.acf-table-body-cont {
    white-space: pre-line;
}

One way to add these styles to the WordPress admin area is adding the following code to your functions.php file of the theme.

add_action('admin_head', 'acf_table_styles');

function acf_table_styles() {
  echo '<style>
    .acf-table-header-cont,
    .acf-table-body-cont {
        white-space: pre-line;
    }
  </style>';
}
How to use the table field in Elementor Page Builder?

In general, its up to Elementor to support ACF field types on the Elementor widgets. All supported ACF fields by Elementor you can find here. But because the table field is not a native ACF field, the support for this field may never happen.

For now the way to go is using the Elementors shortcode Widget. Before you can use a shortcode to display a table fields table, you have to setup a shortcode in functions.php. The following code does this. You can modify the table html output for your needs.

function shortcode_acf_tablefield( $atts ) {

    $a = shortcode_atts( array(
        'table-class' => '',
        'field-name' => false,
        'post-id' => false,
    ), $atts );

    $table = get_field( $a['field-name'], $a['post-id'] );

    $return = '';

    if ( $table ) {

        $return .= '<table class="' . $a['table-class'] . '" border="0">';

            if ( ! empty( $table['caption'] ) ) {

                echo '<caption>' . $table['caption'] . '</caption>';
            }

            if ( $table['header'] ) {

                $return .= '<thead>';

                    $return .= '<tr>';

                        foreach ( $table['header'] as $th ) {

                            $return .= '<th>';
                                $return .= $th['c'];
                            $return .= '</th>';
                        }

                    $return .= '</tr>';

                $return .= '</thead>';
            }

            $return .= '<tbody>';

                foreach ( $table['body'] as $tr ) {

                    $return .= '<tr>';

                        foreach ( $tr as $td ) {

                            $return .= '<td>';
                                $return .= $td['c'];
                            $return .= '</td>';
                        }

                    $return .= '</tr>';
                }

            $return .= '</tbody>';

        $return .= '</table>';
    }

    return $return;
}

add_shortcode( 'table', 'shortcode_acf_tablefield' );

Then use the shortcode in a Elementors shortcode widget like this, to insert a table from the current page or post

[table field-name="your table field name" table-class="my-table"]

You also can insert a table from another page or post

[table field-name="your table field name" post-id="123" table-class="my-table"]

Or you can insert a table from a ACF option page

[table field-name="your table field name" post-id="option" table-class="my-table"]
Updating a table using update_field()

You can use the ACF PHP function update_field() to change a tables data.

Example: adding a new row

// the post ID where to update the table field
$post_id = 123;

// gets the table data
$table_data = get_field( 'table', $post_id );

// defines the new row and its columns
$new_row = array(

    // must define the same amount of columns as exists in the table

    // column 1
    array(
        // the 'c' stands for content of the cell
        'c' => 'Cell Content of Column 1',
    ),

    // column 2
    array(
        'c' => 'Cell Content of Column 2',
    )
);

// adds the new row to the table body data
array_push( $table_data['body'], $new_row );

// saves the new table data
update_field( 'table', $table_data, $post_id );
Third party plugins issues

Since version 1.3.1 of the table plugin, the storing format of the table data changes from JSON string to serialized array for new or updated tables. The issue with JSON is because of third party plugins that do not properly applying wp_slash() to a post_meta value before updating with update_post_metadata(). This can break JSON strings because update_post_metadata() removes backslashes by default. Backslashes are part of the JSON string syntax escaping quotation marks in content.

The table field plugin prevents broken JSON strings to save as a table field data and throws an error message that explains the issue. But this may also breaks the functionality of the third party plugin trying to update the table data. You could disable the JSON string check in the table field plugin using the following code in the wp-config.php file. But then the table JSON data are no longer protected from destroing by update_post_metadata(). Use the following code in wp-config.php only, if you understand the risk…

define( "ACF_TABLEFIELD_FILTER_POSTMETA", false );

This plugin handles a classic, seemingly simple, but surprisingly (or possibly annoyingly) complex development task of entering a table of data, very smoothly (in my experience). Additionally, I encountered a bug in one of the most recent version, while implementing ACF Blocks using the ACF Table Field Plugin, and the Developer not only replied, but had a fix within 24hrs. While, I'm sure other bugs might take a longer time to resolve, I'm grateful for the quick response and turn around in my experience. Thank you!
