Custom command for all tables

Hi,

thanks for your post, and sorry for the trouble.

This is possible, via a plugin filter hook. What’s the “Custom Command” that you would like to give to all tables automatically?

Hi,

Thanks for your reply.
I have read the document of the DataTables JavaScript library, and would like to filter the table data on the fly via javascript, which need me to access the DataTable javascript object.
The scripts that run on the page are surrounded by jQuery(document).ready(...), so I only can add an initComplete option to the Custom Command to access the DataTable javascript object and write my own scripts.

Hi,

thanks for the explanation!

I think the best way for this would be to add this “Custom Command” via custom PHP code that uses plugin filter hook. For example, you could add this to your theme’s “functions.php” file:

add_filter( 'tablepress_table_render_options', 'schiff7_tablepress_custom_commands', 10, 2 );
funtion schiff7_tablepress_custom_commands( $render_options, $table ) {
  $custom_commands = '"initComplete": ...';
  if ( ! empty( $render_options['custom_commands'] ) ) {
    $render_options['custom_commands'] .= ','; 
  }
  $render_options['custom_commands'] .= $custom_commands;
  return $render_options;
}

Here, you would put your code into that

$custom_commands = '"initComplete": ...';

line.

Hi Tobias,

Thanks for your reply and sorry for the delayed response.

I appreciate that you taking the time to write me the code, but it seems that things still can’t function well yet.

I checked the source code and found the following code in ‘controller-frontend.php’, around line 569:

$render_options = apply_filters( 'tablepress_table_render_options', $render_options, $table );

// Eventually add this table to list of tables which have a JS library enabled and thus are to be included in the script's call in the footer.
if ( $render_options['use_datatables'] && $render_options['table_head'] && count( $table['data'] ) > 1 ) {
    // Get options for the DataTables JavaScript library from the table's render options.
    $js_options = array();
    foreach ( array(
        'alternating_row_colors',
        'datatables_sort',
        'datatables_paginate',
        'datatables_paginate',
        'datatables_paginate_entries',
        'datatables_lengthchange',
        'datatables_filter',
        'datatables_info',
        'datatables_scrollx',
        'datatables_scrolly',
        'datatables_locale',
        'datatables_custom_commands',
    ) as $option ) {
        $js_options[ $option ] = $render_options[ $option ];
    }
    (etc...)
}

Then I updated the $render_options['custom_commands'] to $render_options['datatables_custom_commands'] and saw my code rendered on the page.

Should the $render_options['custom_commands'] be $render_options['datatables_custom_commands']?

Thanks again for your help.
