You can access the original contents of the node at:

<?php
$node->original
?>

Rename the File field name

I have created a field in a content type and added a image field with that. After this i created a node for this and uploaded a image in image field. Now i want to change the filename of image using my custom module function like
custom_changes_node_presave($node). Exactly i want to replace the space from filename while saving the node. My code is mentioned below. Right now i am not able to rename the filename of image.

<?php
function custom_changes_node_presave($node){

    

    if ($node->type ==='designer_background_images'){
        
        $filename =$node->original->field_db_image['und']['0']['filename'];
        $uri       =$node->original->field_db_image['und']['0']['uri'];
        
        $filename    = str_replace (" ", "_", $filename);
        $uri        = str_replace (" ", "_", $uri);
        
        $node->original->field_db_image['und']['0']['filename']= $filename;
        $node->original->field_db_image['und']['0']['uri']       = $uri;
        
        //field_attach_presave('node', $node);
        
            // And the actual field change for the given node (e.g. entity).
            
        //field_attach_update('node', $node);
        
        // echo "<pre>";
            // print_r($node);
        // exit;
        // print $node->original->field_db_image['und']['0']['filename'];
        // print $node->original->field_db_image['und']['0']['uri'];
    }
}
?>

use $node instead of $node->original?

To change the new value, shouldn't you be using:

$node->field_db_image['und']['0']['filename'] = $filename;

IN the case above, the module is called custome_changes.

can we redirect from normal node/[nid] page

How can we redirect from the default results page after editing a node?

Something like $form['#redirect'] = 'redirect/path' ?

Use form alter

Posted by jdubbwya on February 8, 2012 at 5:41pm

To updated the form state you need to use the hook_form_alter or hook_form_FORM_ID_alter to add an additional submit handler. An example:

function example_form_node_form_alter(&$form, &$form_state, $form_id) {
  $form['#submit'][] = 'example_node_form_submit_redirect'; 
}

function example_node_form_submit_redirect( $form, &$form_state ){
  $form_state['redirect'] = "redirect/after_submit";
}
