Renamed file upload to update in custom post type

Hi,

I am needing some assistance with a custom post type and gravity forms. I have got everything working properly using the Gravity Forms + Custom Post Types plugin.

I have an upload field where a file is uploaded and then this is put into a custom post type field with the url to the file. This seems to be working properly except one problem. I have added code to my functions.php file to rename the file after it uploaded (referencing this post http://www.gravityhelp.com/forums/topic/renaming-uploaded-files-before-saving )

but when i view the post in the custom post type it still shows the original file name before it was renamed. Is it possible to have this automatically update in the custom post type as well?

Any help would be greatly appreciated!
Thank you.

Hi Chris,
I am new to Gravity Forms and was able to rename my upload file using the info in this post:
http://www.gravityhelp.com/forums/topic/file-upload-location-and-name#post-76119. It looks great when I log into the WP admin and view the entry, but the problem is that the file name and link in the notification email sent to the client is not updated with the new file name.

Please let me know if there is a way to change the link and filename within the notification also.

Thank You for your help,
Jessica

Hi Chris,
Here is where the form is currently:
http://awo.aws.org/professional-program-abstract-form/

It's just been uploaded a few days ago so I do not have many files to rename at this point, but would like to have this functionality in place for the future.

Thanks Chris,
Jessica

Hi Chris,
I am using the exact code from this link:
http://www.gravityhelp.com/forums/topic/file-upload-location-and-name#post-76119
I just changed the references to form 9 to 1.

I would like to have the files renamed using the id# because the uploaded files from each submission are tests that need to be evaluated anonymously as well as easily linked to the database submission. The uploaded file that is attached to the notification email is what my client would like to use as her reference to the file rather than logging into the WordPress admin since she is not involved with the site itself in any other way.

Please let me know if you need anything further from me.

Thanks,
Jessica

Hi Sorry for the extremely late response. Here is my code that I am using for this:

add_action("gform_post_submission", "rename_file", 10, 2);
function rename_file($entry, $form){

    //---------------------------------------------------------
    //---------------------------------------------------------
    //REPLACE THESE THREE VARIABLES BASED ON YOUR ACTUAL IDs
    $form_id = "1";
    $fileupload_field_id = "6";
    $name_field_id = "1";
    //---------------------------------------------------------
    //---------------------------------------------------------

    //ignore other forms
    if($form["id"] != $form_id)
        return;

    $upload_info = wp_upload_dir();

    //original name/path
    $original_file_url = $entry[$fileupload_field_id];
    $original_file_path = str_replace($upload_info["baseurl"], $upload_info["basedir"], $original_file_url);
    $original_file_info = pathinfo($original_file_url);

    //New File Name (without extension).
	$nospaces = $entry[$name_field_id];
	$nospaces = ucwords(strtolower($nospaces));
	$nospaces = str_replace(' ', '', $nospaces);
    $new_name = "TS-" .  $nospaces . "_" . $entry["id"];

    //adding same extension as original
    $new_name .= "." . $original_file_info["extension"];

    $new_file_url = str_replace($original_file_info["basename"], $new_name, $original_file_url);
    $new_file_path = str_replace($original_file_info["basename"], $new_name, $original_file_path);

    //rename file
    $is_success = rename($original_file_path, $new_file_path);

    //if file was renamed successfully, updating entry so that it points to the new file
    if($is_success){
        global $wpdb;
        $wpdb->update(RGFormsModel::get_lead_details_table_name(), array("value" => $new_file_url), array("lead_id" => $entry["id"], "value" => $original_file_url));
    }
}

The Meta name for the field in the custom post type is "sample-upload"

Thank you

I've just hit this problem too. The previously published solution is complex, and involves modifying the DB after the lead record has been written. This also - as we now know - takes place too far down the track to affect anything in the notification emails and - often - data sent to other plugins.

Instead, as suggested above, I hooked into the much earlier "gform_pre_submission_filter", which triggers when the form is POSTed back, and before any processing is done. The code below is pretty basic (it'll run on every form - if you need something more specific, add a form filter check at the start) and just loops through the $_FILES array, replacing any filename it finds with a pseudo-random MD5 hash. (You could, obviously, replace this with any algorithm you wish to generate the filename.)

However, remember that as this happens long before the DB write, you don't have access to a Lead ID or any other DB-related data; any other submitted form data you want to use will have to be got the old-fashioned way directly from $_POST - be careful to properly escape any field you plan to redisplay or use in an unexpected way to avoid the creation of potential XSS or SQL-injection vulnerabilities.

// Force uploaded filenames to a unique hash BEFORE form is processed
add_filter("gform_pre_submission_filter", "wired_set_upload_filenames", 10, 1);
function wired_set_upload_filenames($form)
{
 	foreach($_FILES as &$file)
	{
		$oldname = $file['name'];
		$newname = $oldname;
		$ext = '';
		$dot = strrpos($oldname,'.');
		if ( false !== $dot )
		{
			$ext = substr($oldname,$dot);
			$newname = md5( mt_rand().$oldname );
		}
		$file['name'] = $newname . $ext;
	}
    // Return form object
    return $form;
}

Hope this is of help to others in the same boat.
