Codeigniter $this->input->post() empty while $_POST is working correctly

Question

On a codeigniter installation, I am trying to use the inbuilt $this->input->post(\'some_data\') function, however $this->input->post()

Answer 1

Upgrading from 2.2.x to 3.0.x -- reason post method fails. If you are upgrading CI 3.x, need to keep the index_page in config file. Also check the .htaccess file for mod_rewrite. CI_3.x

$config['index_page'] = ''; // ci 2.x
$config['index_page'] = 'index.php'; // ci 3.x

My .htaccess

<IfModule mod_rewrite.c>
 RewriteEngine On
 RewriteBase /
 RewriteCond %{REQUEST_FILENAME} !-f
 RewriteCond %{REQUEST_FILENAME} !-d
 RewriteRule . /index.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
 ErrorDocument 404 /index.php
</IfModule>

Answer 2

Finally got the issue resolved today. The issue was with the .htaccess file.

Learning to myself: MUST READ THE CODEIGNITER DOCUMENTATION more thoroughly.

Answer 3

To use $this->input->post() initialize the form helper. You could do that by default in config.

Answer 4

Change your form action,

From this:

<form method="post" action="<?=base_url()?>yourprocess">

Into this:

<form method="post" action="<?=base_url()?>index.php/yourprocess">

Basically, you just need to add "index.php" after your base_url():

action="http://www.yourdomain.com/index.php/yourprocess"

Answer 5

My issue was with an ajax call. I was using this:

type: 'posts',

instead of

type: 'post',

Syntax, D'oh!

Answer 6

Solved as follows:

Does the following exclude the redirection that is .htacess that will run the $ this-> input- > post ('name' ) on the controller, in my case it worked perfectly .
