Resolved Action Hook For When A Custom Section Is Updated

[infogroupsmb 1]

I am attempting to write a custom function to send the header and footer areas of the the pages to a .net web service anytime the content of the header or footer area is updated. I have worked out the WordPress action hook for when the menus are updated,

add_action( 'wp_update_nav_menu', 'write_html' );

, but I need to also call my function when the header or footer sections are updated via pagelines. We have custom sections that are being used for the header and footer areas.

I have looked through the Action hooks here: http://api.pagelines.com/hooks

and watched the hook tutorial here: http://www.pagelines.com/docs/base-child-theme

The video is talking more about Filters than Actions (using WordPress terminology) and the list of Actions in the api page doesn't show anything that might relate to updating a specific section.

So I have 2 questions:

1. Is there a pre-exisiting Action hook for when a custom section's site wide settings are updated such as through PageLines > Page Options and selecting the section?

2. If not, how can a custom Action hook be added to a section's update?

Hi there, I honestly don't know the answer on that one, but I will forward your request on to one of our developers and either myself or someone on the team will get back to you shortly to advise further.

Wordpress has a built in action hook for any option saved to the database, so you can use option_pagelines-settings-two

If I understand you correctly Simon_P option_pagelines-settings-two will trigger when any option is saved. Is there a way to add an action hook to a specific custom pagelines section? Otherwise option_pagelines-settings-two will be triggering all the time and I only want to do all the processing and call the web service when the menus, custom header section or custom footer section are updated.

Oh right, well in that case you could the ploption filter....

so if the option is footer_text for example, filter will be ploption_footer_text

Its a filter so you MUST pass the option back. You can see it in use here http://phpxref.pagelines.com/includes/library.options.php.source.html

Actually thats not gonna work...

This is how id suggest you do it...

First add an action that hooks into the option_pagelines-special option...when its triggered it can copy the settings you are monitoring to a temp setting. The the next time it is triggered, it can compare the saved 'new' setting with your temp setting ( the old one ), if they are different then fire your API calls.

We don't really care that much if the actual value of the option is being changes, just that someone has updated it. Also, it's not necessary to trigger this when someone makes a page specific change, but only when they update the site default options through pagelines > page options > site defaults.

[Simon 248]

In that case just use the option_pagelines-special option action

May I ask for an example? For instance in order to call my updater function when a WP menu is changed I use

add_action( 'wp_update_nav_menu', 'write_html' );

So to trigger the same function when the the page options for the custom header and footer sections are updated I'd use

add_action( 'option_pagelines-special', 'write_html' );

?

And if that is correct, how does it know to only trigger when specific page options are changed, i.e. the header and footer options? I was assuming I'd have to add some custom hook to those 2 sections.

Ok so

add_action( 'option_pagelines-special', 'write_html' );

seems to trigger any time someone navigates to any page options page, not just when an update occurs.

and

it seems to trigger every time a ploption is pulled to populate the page options page which means it is calls WAY too many times (and has even caused the script to timeout now)

[infogroupsmb 1]

Simon, though

add_action( 'option_pagelines-special', 'write_html' );

didn't work your suggestion lead me in the right direction. The hook I ended up using is

add_action( 'update_option_pagelines-special', 'write_html' );

Thanks for pointing me in the right direction
