如何在Codeigniter的控制器中获取输入值

Question

I am quite new to CodeIgniter. In my application I have page where user enters his details. I want to get that detail in a variable (Lets say just Name ) and want to use that variable in one of the controller file.

How to do that ?

Answer 1

From http://ellislab.com/codeigniter/user-guide/libraries/input.html :

$post = $this->input->post();
//on the controller you can access this and will return the array
//of the post data you submitted

You can also get them by variable name like:

$somedata = $this->input->post('some_data');

Make sure your form action is pointing to your controller as well. :)

Answer 2

for a form value called "supername"

to use locally inside a method

$supername = $this->input->post( 'supername', TRUE ) ;

to use in any method in the class use $this->

$this->supername = $this->input->post( 'supername', TRUE ) ;

Answer 3

In your controller

$name= $this->input->post('name');

Better start off with some tutorials on Codeigniter.

Answer 4

CodeIgniter has this Input class wherein simplifies the inputs when they are used in some conditional statements.

To answer your question, on how to fetch the data entered by the user is by:

$name = $this->input->post('name');

Stores the value of name (it is the name of your field in the form) to a variable name $name .

Do you want to know if the field is empty or not?

try:

if($name = $this->input->post('name')){
    //$name has the value of the name field and it is not empty, do something.
}else{
    //$name has the value of the name field and it is empty, do something.
}

CodeIgniter Input class also has XSS Filtering capabilities, it filters input automatically to prevent cross-site scripting attacks.

All you have to do is:

Set it to TRUE in your config/config.php

$config['global_xss_filtering'] = TRUE;
