I am facing the following issue :
I used to keep all the styling in a theme options page. When the user clicked the save button, i had a backend script that generated a css file with the changes so that they will not be output inline in each page. This has a lot of benefits, amongst them caching.
I have switched to the Theme Customizer, and everything is fine except i can't find a way to hook into the the "save" button. I would like to trigger a function that updates the content of the css file when that button is clicked in the backend.
Is this even possible ?
Thanks !
Since WordPress 3.6.0 you can now call customize_save_after.
<?php
function emailAdmin(){
mail('your#email', 'Woza!', 'You won\'t believe this but someone has updated the theme customizations!!');
}
add_action( 'customize_save_after', 'emailAdmin' );
?>
More info: http://developer.wordpress.org/reference/hooks/customize_save_after/
I'm facing the same situation. The customize_save works BEFORE the options are saved, so that's out. I've emailed Otto (ottodestruct.com) about it.
The solution I have right now is as follows:
add_action('customize_save', 'regenCSS', 100);
function regenCSS( $wp_customize ) {
checkCSSRegen(); // Checks if I need to regen and does so
set_theme_mod('regen-css', time()+3); // Waits 3 seconds until everything is saved
}
function checkCSSRegen() {
if (get_theme_mod('regen-css') != "" && get_theme_mod('regen-css') < time()) {
makecss();
remove_theme_mod('regen-css');
}
}
I also add an extra checkCSSRegen(); to my customize_controls_init function.
Again, this is a little bit of a hack. Unfortunately, it's the best I can find to do at the time.
Another option would be to use a ajax response that just pings a php file. That feels even more of a hack than this.
Another quick hack would be to do a javascript action that when the save button is clicked, it sets a timer to delay a call to a PHP file that runs the compile. That is VERY hacky to me.
The only fallback of the above, is unless the customizer is reloaded or another value saved, you may not get all the values you want.
Anyone else have a better idea?
** Update **
Just added the following request to the Wordpress team. Hopefully we'll get it squeezed in there.
http://wordpress.org/ideas/topic/do-customize_save-action-hook-after-the-settings-are-saved?replies=3#post-24853
* Update 2 *
Looks like it will be in the 3.6 release as customize_save_after. Guess a few tweets and example code can make stuff happen even with the Wordpress team. ;)
As describe by #Dovy already you can hook customize_save_after to do this now:
do_action('customize_save_after', 'savesettings', 99);
When savesettings save settings to a file it will be bad practice to do this with native php file functions (like file_put_contents()) as described here: http://ottopress.com/2011/tutorial-using-the-wp_filesystem/ by #otto.
Solution for file saving will be to use wp_filesystem. To use wp_filesystem you will need the file credentials (ftp) of the user.
customize_save_after will be called in a AJAX request and the result won't be visible. Cause of the AJAX handle you can't ask the user for the file credentials which requires a form submit.
Solution can be found by saving the file credentials to wp-config.php and add them ( temporary ) to the database. Doing this savesettings can read the credentials from the database and use them to save the file by using credentials. (this solution is described in more detail here: https://wordpress.stackexchange.com/a/126631/31759)
Not tested, but there is the action hook customize_save in /wp-includes/class-wp-customize-manager.php.
It's inside the save() function:
/**
* Switch the theme and trigger the save action of each setting.
*
* #since 3.4.0
*/
There are some other interesting action hooks (do_action) in this file that may be worth check.

Using the Avada theme's form builder functionality, I’m attempting to use the “Send to URL” option to POST the form and then run an api call in a plugin I’ve written.
I was thinking I could set the “Send to URL” value to /wp-admin/admin-post.php and add a hidden field to the form named “action” with a value of “make_api_call” to get it to run the code in my plugin set up like so:
add_action('admin_post_make_api_call', 'make_api_call');
function make_api_call()
{
//todo: make the api call
wp_redirect(‘another-page’);
}
However, this does not work and returns this from the server: {"status":"error","info":"url_failed"}
What I want to do is to POST the form to admin-post.php, have my plugin run code when it POSTs, and then redirect to another page.
I've checked the documentation for the AVADA theme and it only says that you can specify a url to post to but doesn't give any additional details.
So I eventually got something to work, and I'm not knowledgeable or experienced enough with WordPress development to know if it is the "right" way, but it works well.
I realized that using the "Send to Url" option on the Avada form, it was POSTing the form to the admin-ajax.php file. There's plenty of documentation on that and I was able to partially make that work but I was not able to make it fit my use case b/c even though there is a way to configure the Avada form to redirect to a different URL on success I couldn't append parameters to that URL based on the return value from admin-ajax.php.
For future reference, here's what I was able to make work but not fit my use case by having the Avada form submission set to Send to Url. (I'm recreating this and some of it's from memory since I went with a different solution, so it may not be 100% runnable.)
The way admin-ajax works is all requests to admin-ajax.php are eventually handled by a WordPress action (filter?) like so:
add_action( 'wp_ajax_my_action', 'my_function' );
In the above, my_action is what you've set as the form's action by creating a hidden input element on your html form named action and setting it's value to "my_action". The my_function argument is the name of the function you want to run when the action happens.
add_action( 'wp_ajax_my_action', 'my_function' );
function my_function(){
//do stuff
}
Watching the request in Chrome's dev tools, I could see the action the form was setting was fusion_form_submit_form_to_url.
So ended up with this:
add_action( 'wp_ajax_fusion_form_submit_form_to_url', 'my_function' );
function my_function(){
//do stuff
}
You can see that the url you enter in the Form Submission URL field gets passed to admin-ajax as fusionAction. Whether the Avada theme does something additional with that - I don't know but you could use it to control the logic that gets executed in my_function. I suspect there's an action in the Avada form that works similar to the wp_ajax_ WordPress action but by the time I got this far I realized this wasn't going to work so I pivoted to the actual solution, below.
All of that worked okay but you can't redirect out of a call to admin-ajax.php unless you do it on the client side and I didn't want to dive into that.
What I was able to make work was configuring the Avada form to do a traditional HTTP POST. I added a hidden input element on the Avada form with a name of formName and the value set to the name of the form I wanted to handle.
In my plugin code, I hooked into the WordPress init action as in the code sample below, and then customized the logic to be executed based on which formName was sent in.
add_action('init', 'callback_function');
function callback_function()
{
if (isset($_POST['formName'])) {
$form = $_POST['formName']; //from the hidden input element "formName"
//there is a call to wp_redirect in each case
switch ($form) {
case 'form1':
process_form_1();
break;
case 'form2':
process_form_1();
break;
default:
# code...
break;
}
//without this "exit" you will get errors similar to "headers already sent"
exit;
}
}
This allowed me to run the code I needed to run based on what form was submitted, and redirect to the correct place afterward.
I'm using a WordPress plugin for accepting online bookings (Appointment Hour Booking) and I need to attach a file to the emails sent after submitting the booking request (a PDF file with the general booking terms). I already applied a solution by editing the calls to the wp_mail() function in this way:
wp_mail(trim($payer_email), $subject, $message,
"From: ".$from."\r\n".
$content_type. "X-Mailer: PHP/" . phpversion(),
array(WP_CONTENT_DIR . '/uploads/agreement.pdf'));
The above works but everytime the plugin updates the file is overwritten and I've to reapply the code modification again. There is a better way to do that without being affected by the plugin updates or there is a way to prevent partially or completely a plugin update in WordPress?
Thank you in advance for any help.
Disabling the plugin update isn't a good idea, you may lost important compatibility or security updates. The way the call to the wp_mail() was modified also causes other attachment-related features stop working. The plugin you mention has a filter that can be used to modify the list of attached files, you can put the following code for example into your theme’s functions.php file:
add_filter( 'cpappb_email_attachments', 'my_attach_function', 10, 3 );
function my_attach_function( $attachments, $params, $form_id )
{
$attachments[] = WP_CONTENT_DIR . '/uploads/agreement.pdf';
return $attachments;
}
With the above code located out of the plugin files your file is added to the list of attachments without removing other attachments and locating the code out of the plugin files will prevent being overwritten by the plugin updates.
Your options are:
Fork the plugin and customize it to your needs.
Ask the team behind the plugin to implement a filter hook to allow customizing the headers passed to the wp_mail() function (so you can then attach files to e-mails).
Keep doing what you have been doing until now.
I like option two the best because:
It allows you to customize the behavior of the plugin from the outside, and,
Your changes will survive plugin updates.
I am trying to use the hook_webform_submission_insert in my theme template.php file. I have 2 other webform hooks currently running in here and they work just fine. I am trying to get the submission data after it has been submitted. Below is my code.
function acquarius_hook_webform_submission_insert($node, $submission){
var_dump($node);
var_dump($submission);
}
I am sure I am missing something small here but everything I try seems to fail.
You need to replace hook keyword with your theme name. Also add hook functions in module.
YOURTHEMENAME_webform_submission_insert($node, $submission){
// give your code here
}
After you create a new hook, you need to clear the drupal caches.
Go to YOURSITE.com/admin/config/development/performance
And click on "Clear all caches"
I just started working with Wordpress (v. 3.6.1).
I have OptionTree installed and as it seems it handles the Theme Options page. I want to run my function (in a plugin or wherever else) right after the user saves the changes of this page.
So far I found out that option-tree/includes/ot-settings-api.php generates the form and it sets the form action to options.php (which is a wordpress core file). I was thinking about change the action to my custom php file and handle the save procedure and finally runs my own function. But this solution looks pretty ugly.
I wonder if there's another way to get the job done.
Thanks.
Thanks to #Sheikh Heera link (tutsplus) I could find a solution.
I think this is some kind of hack and I still don't know if it is the best way. Anyway I did this:
Create a file your-theme-settings.php in your theme lib folder.
Let Wordpress knows about your file by adding this code in your theme functions.php:
include_once('lib/your-theme-settings.php');
Add this code to your-theme-settings.php:
function your_theme_register_settings() {
register_setting('option_tree', 'option_tree', 'your_theme_validate_options');
}
function your_theme_validate_options($input) {
// do whatever you have to do with $input.
}
add_action('admin_init', 'your_theme_register_settings');
In step 3, I put 'option_tree' as 1st and 2nd argument of register_settings function, because I noticed that the Option Group and Option Name of OptionTree plugin is option_tree.
I'm not sure if this is the best solution, so I would be glad if you shares your ideas.
I am trying to trigger an even upon saving / updating a post in wordpress... see here:
add_action('save_post', 'generate_location');
function generate_location($post_id) {
echo "hey";
}
the problem is that its not working...
any ideas why? Syntax?
WordPress implements the Post/Redirect/Get pattern to avoid duplicate form submissions, so you're not going to see anything echo'd from a save_post callback.
Instead, you can do a wp_die( 'hey' ) instead, or log something to the database or file system.
I don't know whether you got this working, but I was having the same issue and discovered how to fix it!
in wp-includes/post.php on line 2940 (at the time of writing), this if/else is run whilst saving a post:
if ( !empty($page_template) && 'page' == $data['post_type'] ) {
You will notice that, if there is an error with the template the function stops there and save_post is never called.
In my case, the posts I was trying to save were imported from a pre-existing site. The new site had no page templates at all, so WP was still trying to save the page with the template from before, failing, and thus; save_post was never called.
I added
/* Template Name: Default Template */
to page.php, bulk edit, selected the template and saved. Remove the template name from page.php (as it shows up twice(, and now save_post is triggered every time.
This was the solution in my case anyway. i'm sure it'll affect someone else, somewhere down the line.
