Load/save file

[Timo]

I have some JavaScript libraries, files on my server, which I use in nuBuilder. My goal is to manage these external files by means of a form.
When I open a record, an external file should be loaded in a nuBuilder textarea field. When I save the record, the content of the textarea should be saved back to the JavaScript file.

Hi,

This is how I implemented a tiny file editor.

Create a table with these fields:

file_id - type varchar(25) - primary key
file_name - type varchar(1000)
file_content - type text

Create a Browse/Edit Form with "Fast Forms". Fields field_name (input), file_content (textarea)

In your form's Custom Code (JS):

Code: Select all

if (nuFormType() == 'edit') {

    var c = atob(fileGetContents());
// instead of atob: use this class to properly decode: https://www.coditty.com/code/utf-base64-encode-in-php-and-decode-in-javascript
    $('#file_content').val(c).change();

    $('#file_content')
        .dblclick(function() {
            nuOpenAce('Javascript', this.id);
        });

    nuHasNotBeenEdited();
}

PHP (BE):

Code: Select all

$c = base64_encode(file_get_contents("#file_name#"));

$j = "
function fileGetContents(){
   return '$c';    
}
";

nuAddJavascript($j);

PHP (AS):

Code: Select all

$filename = "#file_name#";
if ($filename != '')
{
  file_put_contents($filename,stripslashes("#file_content#"));
} 

Whenever a record is saved, the content of file_content is saved to a file that is specified in the field file_name. When a record is opened, the file contents is loaded from the file too.
Hope that helps!
