I have a PHP form that I'd like to adapt for WordPress. I went through and made a plugin that creates a widget and a form. The form action goes to a file I created called listrak-newsletter-api.php but when I submit to it in the below form, I get a 404 error.
These files are all located in my /wp-content/plugins/listrak-newsletter-api directory.
Stand alone, outside of WordPress, this works great. But since migrating it into WordPress, it's becoming quite convoluted. I used to have a simple HTML page with a form that had a form action to listrak-newsletter-api.php and that worked great. But taking this into WordPress seems to have made it a little more difficult than it should be.
Now, I want to keep it as a widget because I'm able to place the widget where I want, on the sidebar, of the WordPress theme. Where it shows up and how it shows up when I activate it are great. Functionality just needs to work.
This file is /wp-content/plugins/listrak-newsletter-api/plugin.php :
<?php

Reset to default 0I think your action URL is wrong. Did you try with
<?php echo plugins_url( 'listrak-newsletter-api.php', __FILE__ ); ?>
like this way:
echo '<form action="' . plugins_url( 'listrak-newsletter-api.php', __FILE__ ) . '" method="post">';
in your code?
Anyway I still recommend you to use WP AJAX to do this. Read here for more information.
