Is there a plugin that supports calling custom functions that you've created?


page A -- I want to call function x


page B -- I want to call function y


I don't want to write the calls in the main input because of others editing and might delete them by misstake...

This is my current solution but not optimal in my eyes :)


        /* Always have wp_footer() just before the closing </body>
         * tag of your theme, or you will break many plugins, which
         * generally use this hook to reference JavaScript files.

        $js =  get_post_meta($post->ID, 'javascript', true);
            if ( $js != "" ) {

<script type="text/javascript">
    <?php echo $js; ?>
<?php } ?>

then I added custom field "javascript" on the pages with their custom functions like this.

function_x(some_variable); function_y(some_var); function_foo(bar);
  • Do you want to avoid using custom fields as well? Nov 16, 2012 at 12:16
  • @kidakaka yes I would like to but... maybe that's to much to ask for though...!

I would create a custom field containing the function to be called, for example called 'function_to_call'. In the templatefile add the code

$function_to_call = get_post_meta( get_the_ID(), 'function_to_call', true );
if ( $function_to_call != "" ) {
    echo '
              ' . $function_to_call . '()

Doing this only outputs the function if you set one in the Custom Fields. You could also make a list of available Functions to avoid Javascript errors.

  • @fish, yeah I did a solution like that but I don't really like it, see my edit.

  • but maybe that's the easiest and most effective solution ...

  • you have to store the values somewhere - so the custom field is your best option. maybe you could create a custom metabox not visible for the editors, containing all the usable functions.

  • Yeah, as you say, I need to store them somewhere and I think custom fields will do it for now. Thanks!
