How to Edit Post Content Programmatically in WordPress

In this Article I am going to edit post content dynamically, with that existing content, I am going to add a footer text like, ” With regards, Author_name,” This not necessary here, but I am just taking it as example. First we need to query the posts using query_post and filter with certain parameters, than choose our necessary post, edit it.

get_row("SELECT post_content,post_title FROM $wpdb->posts WHERE the post title and content $kv_post_title = $kv_post->post_content; $kv_post_content = $kv_post->post_title; ?>

Now, you can print or edit the post title and content using the above two variables. $kv_post_title and $kv_post_content . Here you can simply pass the $kv_post_content and title to wp_editor and create editable fields. Else you can use php function to editing the content and upload it again by using wp_update_post(). Like the following example.

$kv_edited_post = array( 'ID' => 10, 'post_title' => $kv_post_title, 'post_content' => $kv_post_content ); wp_update_post( $kv_edited_post);

That’s it, Now you can edit your posts through programmatically. If you really like my article, Just follow me on below social sites and get more updates from me. If you have any doubt or require further clarification just comment it on next tab. Let me help you to fix it.

I want to do exactly this sort of thing – update broken links by going through all my (thousands of) posts doing a search/replace of certain types of links known to be broken. However… where does one put code like that you show above? I’m a little bit familiar with WP in that I’ve written PHP functions to add some dynamic content to my blog, but what I’m looking for is not something that generates blog content, but instead makes a once-through pass through all of my blog posts and updates them. Where does one put this sort of code?
Thanks!

Hi wil,
this is a sample snippet to edit a post through programmatically, and there you see I queried with a post So you need to fetch the post Id’s in a loop and query each one by iterating the loop, than you can get each post if you want to append or replace anything , you can do by using normal PHP functions of string .

Using WordPress ‘edit_post()’ PHP function

The edit_post() WordPress PHP function is used to update an existing post with values that are provided in the $_POST superglobal. If post data is given as an argument, it’s processed as an array of data, appropriately keyed for conversion into a post object.

Usage

Here’s a basic usage of the edit_post() function:

$post_data = array( 'ID' => 1, 'post_title' => 'Updated Title', 'post_content' => 'This is the updated content.' ); edit_post( $post_data );

In this case, the function is used to update the post with ID 1. The title is updated to ‘Updated Title’ and the content is updated to ‘This is the updated content.’

Parameters

• $post_data (array|null) (Optional) – This is the array of post data to process. If not specified, the function defaults to the $_POST superglobal. The default value is null.

More information

See WordPress Developer Resources: edit_post()

Examples

Basic usage

$post_data = array( 'ID' => 10, 'post_title' => 'My New Title', 'post_content' => 'New content for the post.' ); edit_post( $post_data ); // Updates the post with ID 10

The above code changes the title and content of the post with ID 10.

Update post status

$post_data = array( 'ID' => 5, 'post_status' => 'draft' ); edit_post( $post_data ); // Changes the post status to draft

This example changes the status of the post with ID 5 to ‘draft’.

Add a post excerpt

$post_data = array( 'ID' => 3, 'post_excerpt' => 'This is a short summary of the post.' ); edit_post( $post_data ); // Adds an excerpt to the post

In this case, an excerpt is added to the post with ID 3.

Change post author

$post_data = array( 'ID' => 7, 'post_author' => 2 ); edit_post( $post_data ); // Changes the post author

This example changes the author of the post with ID 7 to the user with ID 2.

Update post with $_POST superglobal

Assuming that $_POST contains relevant data:

edit_post(); // Updates the post using $_POST data

This example updates a post using data from the $_POST superglobal.
