I have been trying to associate CUSTOM data to each of my WP POSTS using the following piece of code :
if($condition === true){
if ( ! update_post_meta ($post_id, '_someData', $someVariable) ) {
add_post_meta($post_id, '_someData', $someVariable);
}
}
However, seems like the META VALUE is RESET to default i.e. Zero OR Blank. Our WordPress website has around 40 plugins, and I think one of these WordPress plugins, is coming in my way of doing things. All of my logic works fine, on a demo WordPres website. Is there a way for me to have total control to set the META Value for a given POST ? Also, is there a way where I can be notified that the META Key is about to change and then I can decide whether OR not to change the Meta Value ?
Any pointers or reference URL's can be of great help. Thanks !
You only need to call update_post_meta in either scenario. Calling add_post_meta() is not necessary and could be causing this problem.
From the codex:
The function update_post_meta() updates the value of an existing meta key (custom field) for the specified post.
This may be used in place of add_post_meta() function. The first thing this function will do is make sure that $meta_key already exists on $post_id. If it does not, add_post_meta($post_id, $meta_key, $meta_value) is called instead and its result is returned.

I have function that update post content automatically based from custom field like this:
function update_content(){
$mycustomfield = get_post_meta( get_the_ID(), 'customfield', true);
$post = array();
$post['ID'] = get_the_ID();
$post['post_content' ] = $mycustomfield ;
$post['post_title' ] = $mycustomfield ;
// Update the post into the database
wp_update_post( $post );
We update only custom field to make content. For now, we launch this function manually on save_post hook, but the articles are so many and we need now a cron to automate this function: process 4 posts every hour until all posts are completed, then start over.
How to make this, thank you
WordPress actually has a built-in psuedo cron system called WP Cron. It doesn't function exactly like a proper server cron, but can perform a similar function in many cases. You can find documentation on it here:
https://developer.wordpress.org/plugins/cron/#:~:text=WP%2DCron%20is%20how%20WordPress,post%2C%20utilize%20WP%2DCron.&text=WP%2DCron%20works%20by%20checking,what%20needs%20to%20be%20run.
However thinking about your use case and looking at your function above, I'm wondering what the purpose of your cron is? It looks from that function like all you're doing is taking some content already in your database and putting it somewhere else. Why? Why not simply display your custom field in the correct spot? Or better yet, use the fields as intended?
Even if that is necessary - maybe I don't understand fully from the example above - I think your initial inclination to run this on save_post is much more correct. Unless there's some information external to your site that's changing, the only time these values will change is when you save the post. So what is the purpose of running it on a schedule?
I'm new to WP development. I need to write a hook to check if the currently logged in user is viewing a post listed within a specific category, and then redirect user if they're lacking certain meta data.
I tried creating this function:
add_action('init','check_user_post_category');
however inside that function I was unable to get the post object (I have tried everything I found on the web!)
global $post; // This object is not valid at this time
global $wp; // $wp->request is empty
$_REQUEST; // This var is giving me an empty array! Is this normal??? :(
Could you kindly suggest, what hook is best to use in this case, and how to get the post object? Many thanks!
Use 'wp' hook instead of 'init'.
add_action('wp','check_user_post_category');
Maybe this would work for you.
I have a WooCommerce set up, whereby all orders are added manually.
When I add a (pending) order, the WooCommerce order status hook registers the sale (for reporting).
I wish the switch this process to the hook called only when the order is (again manually) set to 'complete'.
There are a couple plugins ( eg. https://docs.woocommerce.com/document/woocommerce-order-status-control/ / https://wordpress.org/plugins/advanced-reporting-for-woocommerce/ etc ), but these are either overkill or simply don't provide this functionality..
I've also found a couple related posts, essentially describing overriding the woocommerce hooks to this end ( Getting order data after successful checkout hook etc, but unfortunately whilst the solutions correspond ( ie adapting the correct hooks - the context differs ).
I'm reluctant to prevent functionality in these hooks when attempting to overwrite/reorder the actions so any pointers which hooks I can use to achieve this would be really helpful.
Many thanks!
maybe you can try to use the ... filter, something like (untested):
add_filter( 'woocommerce_reports_order_statuses', 'fc_order_status_reports', 20, 1 );
function fc_order_status_reports( $statuses ) {
$statuses = array('completed');
return $statuses;
}
The code snippet is to add to your active theme's functions.php file.
Let me know if it does the job ;)
Hard to define the Title of this Question....
I want to create a nice readable permalink structure for my 2 custom post types (CPT).
My first CPT "family" has the following rewrite-slug "family/%postname%" (all works fine)
The second CPT "childs" has a metabox where I can select the parent_id-field by choosing a CPT "family" where the child-CPT belongs to. That also works great.
Now I set the rewrite-slug for "childs" to "%parent_post_url%/child/%postname%" so that I can get the following URL "family/the-griffons/child/peter" . But when I call this URL wordpress displays a not-found-page. The crazy thing is that if I set the rewrite-slug hard to "family/the-griffons/child/%postname%" I can call the URL (both URLs are the same!!!)
So why toes WP throws an error when I try to get the URL dynamically but not when I hardcode the URL??
The child-parent relationship you think you have is not quite there. Based on what you've told us so far, it seems that all you have is a custom field denoting the "pseudo-parent" id. So what your question should really read is
How do I rewrite the first part of the cpt url, based on the cpt custom field value ?
because, as far as wordpress is concerned in your case, that's all that "parent id" really is- a custom field value.
you can try following the last part(Part 3.) of this tutorial, keeping in mind, that you'll want the actual path of the url of the "parent id" and not the cf "parent id" value itself, you'll have to implement something along the lines of:
$parent_id = get_post_meta($post_id, "your_cf_key_for_parent_id", true);
$full_parent_post_url = parse_url( get_permalink( $parent_id ) );
$parent_post_url = $full_parent_post_url['path'];
if(!$parent_post_url) { $parent_post_url = "default-fallback" }
$permalink = str_replace(‘%parent_post_url%’, $parent_post_url, $permalink);
return $permalink;

using-custom-fields-in-custom-post-type-url
BUT as #c0ns0l3 mentioned using custom taxonomies IS the proper way to go about this.
I'm using Contact Form 7 in a wordpress site with multiple forms.
I need to direct one form to a different form action url than the others.
I found the reply below for a previous thread but I'm not sure how to go about it.
Can someone specify what exact code needs to be included in "additional settings"
and what the code in functions.php would look like?
Thanks for your help!
reply from diff. thread, which I don't completely understand...
*Yes, you have to change the "action" attribute in the form using this Filter Hook wpcf7_form_action_url. (what would be the code?) You could add the hook into your theme's functions.php and then just process the form data in your ASP page.(code?) *
Since you're not familiar with PHP code at all, I'll give you a bit of a crash course in coding within the Wordpress API.
First off, you need to know the difference between functions and variables. A variable is a single entity that is meant to represent an arbitrary value. The value can be anything. A number, somebody's name, or complex data.
A function is something that executes a series of actions to either send back - or return - a variable, or alter a given variable.
<?php
$a = 1; //Number
$b = 'b'; //String *note the quotes around it*
$c = my_function(); //Call to a function called my_function
echo $a; //1
echo $b; //b
echo $c; //oh, hello
function my_function()
{
return 'oh, hello';
}
?>
Wordpress utilizes its own action and filter system loosely based on the Event-Driven Programming style.
What this means is that Wordpress is "listening" for a certain event to happen, and when it does, it executes a function attached to that event (also known as a callback). These are the "Actions" and "Filters". So what's the difference?
Actions are functions that do stuff
Filters are functions that return stuff
So how does this all fit in to your problem?
Contact Form 7 has its own filter that returns the URL of where information is to be sent by its forms.
So lets look at the basics of a Filter Hook
add_filter('hook_name', 'your_filter');
add_filter is the function that tells Wordpress it needs to listen
for a particular event.
'hook_name' is the event Wordpress is listening for.
'your_filter' is the function - or callback - that is called when the 'hook_name' event is fired.
The link to the previous thread states that the hook name you need to be using is 'wpcf7_form_action_url'. That means that all you have to do is make a call to add_filter, set the 'hook_name' to 'wpcf7_form_action_url', and then set 'your_filter' to the name of the function you'll be setting up as your callback.
Once that's done, you just need to define a function with a name that matches whatever you put in place of 'your_filter', and just make sure that it returns a URL to modify the form action.
Now here comes the problem: This is going to alter ALL of your forms. But first thing's first: See if you can get some working code going on your own. Just write your code in functions.php and let us know how it turns out.
UPDATE:
The fact that you were able to get it so quickly is wonderful, and shows the amount of research effort you're putting into this.
Put all of this in functions.php
add_filter('wpcf7_form_action_url', 'wpcf7_custom_form_action_url');
function wpcf7_custom_form_action_url()
{
return 'wheretopost.asp';
}
As mentioned before, that will affect ALL of your forms. If this is only supposed to affect a form on a given page, you can do something like this:
add_filter('wpcf7_form_action_url', 'wpcf7_custom_form_action_url');
function wpcf7_custom_form_action_url($url)
{
global $post;
$id_to_change = 1;
if($post->ID === $id_to_change)
return 'wheretopost.asp';
else
return $url;
}
All you would need to do is change the value of $id_to_change to a number that represents the ID of the Post/Page you're trying to affect. So if - for example - you have an About Page that you would like to change the Action URL, you can find the ID number of your About Page in the Admin Dashboard (just go to the Page editor and look in your URL for the ID number) and change the 1 to whatever the ID number is.
Hope this helps you out, and best of luck to you.
Great answer #maiorano84 but I think you should check form ID instead of Post. Here is my version.
add_filter('wpcf7_form_action_url', 'wpcf7_custom_form_action_url');
function wpcf7_custom_form_action_url($url)
{
$wpcf7 = WPCF7_ContactForm::get_current();
$wpcf7_id = $wpcf7->id();
$form_id = 123;
return $wpcf7_id == $form_id? '/action.php' : $url;
}
Another thing you might need to disable WPCF7 AJAX. That can be disabled by placing the following code in your theme functions.php
apply_filters( 'wpcf7_load_js', '__return_false' );
You can add actions after a successful submission like the documentation says
Adding a filter will work in the sense that it will change the action on the form but unfortunately it will also break the functionality of the plugin. If you add the filter like other answers suggest the form will keep the spinner state after submission.
You can make the form do something else on submit by using advanced settings such as:
on_submit: "alert('submit');"
more details about advanced settings here.
According to #abbas-arif, his solution works great, but have a limitation. This solution change the form's action on all forms present in post with that ID.
A better solution should be to use directly the form's ID. To get it, whit wordpress >5.2, you can use:
add_filter('wpcf7_form_action_url', 'wpcf7_custom_form_action_url');
function wpcf7_custom_form_action_url($url)
{
$cf7forms = WPCF7_ContactForm::get_current();
$Form = $cf7forms -> id;
switch($Form){
case 1:
return 'destination like salesforce url 1...';
case 2:
return 'destination like salesforce url 2...';
case 3:
return 'destination like salesforce url 3...';
default:
return $url;
}
}
