button to

Purpose

The idea is simple (and copied from Rails): it is a helper that creates a post form with a submit button. Optionally, it can have input hiddens as a array in the last parameter.

It has great value in lists of records that have options that are not "elegant" send them as get parameters.

Usage

<!-- Simple button --> <?php echo button_to( 'Button value' , 'controller/action' , array('hidden_name' => 'value' )) ?>

<!-- Personalized --> <?php echo button_to( array('value' => 'Button value', 'class' => 'css Class') , 'controller/action', array('hidden_name' => 'value' )) ?>

Helper code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

/**

• Creates a post form with a submit button.
• @access public
• @param mixed button's value or array with html configuration
• @param string (module/)controller/action to post.
• @param string associative array (hash) with key equals to hidden field's name and value equals to hidden's value.
• @return string */

if ( ! function_exists('button_to')) {

function button_to( $button_format, $destination , $hiddens = null)
{
    $CI =& get_instance();    

    $html = "<form action='{$CI->config->site_url($destination)}' method='post'>";

    if (!empty($hiddens))
    {
        foreach ($hiddens as $key => $value)
            $html .= "<input type='hidden' name='$key' value='$value' />";
    }


    if (is_array($button_format))
    {
        $html .= "<input type='submit' "; 

        foreach ($button_format as $key => $value)
            $html .= $key . "='". $value . "' ";
    
        $html .= "/>";
    } else {
        $html .= "<input type='submit' value='{$button_format}' />";
    }

    $html .= "</form>";

    return $html;
}

}
