Wordpress表格处理

Question

I have created a form on my wordpress site, a function to process the data located in functions.php, and an action php file. I have tested the processing function and know it works, but I'm having trouble getting everything to communicate with wordpress.

update_item_meta.php is located in my theme directory.

Form Opening Tag

<form method="post" id="project-info" action="/wp-content/themes/Avada/update_item_meta.php">

update_item_meta.php

<?php
//connect to WP
define('WP_USE_THEMES', false);
require('../../../wp-load.php');

//call function from functions.php to process form data
update_item_meta_data();
?>

Note: wp-load.php is located in the main site root

If someone could help me out I would really appreciate it. If i had to guess it's a problem with either the path to update_item_meta.php in the form action or update_item_meta.php, but I haven't been able to figure it out.

Answer 1

action="/wp-content/themes/Avada/update_item_meta.php"

You will obviously not load wp calling a php file directly and using relative paths to load wp is problematic.

The best way to deal with forms in wp are to post to the same url:

1. action="#" with a hidden input for a unique field to identify your form and in your functions file a function to pick up the post action....

   if($_POST['unique']){
     require_once 'yourfile.php';
     //or your form process code here
   }
   

2. action="#" and place code to handle the post in your template file (not the wp way but helps prevent a load of code from being loaded that is not relevant to the page.

Both ways will have wp loaded for you without having to manually load.
