I'm now to FrontEnd-Development with React.
To make sure having the maximum flexibility, I want to load some variables from a specific CustomConfigFile.
This file should be generated if it's not found and can be loaded and edited on the UI.
Can somebody tell me whether this is possible at all and give me an example?
There are three steps you need to do:
If you want to achieve something like that, you need to store those values either in a database or a file in the server, you can use JSON, XML or whatever format you want.
Your client needs to load this file at runtime, you can use fetch for this.
Now, for the editing part. You are going to need an endpoint you can call from your client, that is able to update those values in the database or in the file. You can use node.js, PHP, ruby or whatever backend language you are comfortable with.
That's the logic you need to implement, I've done it with React + Laravel + MySQL for this app: https://bleext.com/music people can change title, logo, language, the main menu, templates, and so many other things to customize the system.

The title says it all. I need to create a form that the user fills in and on submit, I want the data to go to a database and a PDF to a directory on the server.
I don't think AngularJS can do all of these things, can it? I'm very new to programming -- trying to crossover from HTML/CSS/JS to more in-depth projects.
Can anyone please suggest the best course for this? What language for the form, writing to the DB and generating a PDF? I can do the rest of the research and build it out once I have some direction.
How would you go about achieving this?
Thanks!
Ugh. I forgot to mention that PHP is not an option. Is there another way?
All you need is to apply the paradigm Client / Server.
With angular.js you can build the client software for handling the form but this is not necessary...
With a single script php you can generate the page with the form and handling the incoming data.
You can use a standard relational database like mysql for storing it and, about the pdf, take a look here
I have a site that I'm looking to transfer to Volusion. Importing tabled content into Volusion's a breeze, it's getting it tabled that's an issue. The old site has no real ability to export, nor do I know how to get at it's database. I'm thinking there must be some sort of script I can write to take the content from the frontend and download it in some sort of list that I can put into a CSV, and put into Volusion.

Any suggestions? I'm hoping to get in the image directory as well and download all them for upload to the new site.
You are going to need at the very least a file with product code, product name, weight and price.
Looking at the URL you provided it doesn't appear that the products their follow any type of orderly structure where you can target the images folder or products based on a known piece of information like a products code. Unless the back-end has some type of product export function you may have no choice but to recreate it from scratch.
I don't know if you solved this yet or not, but I would suggest scraping the data providing you have the information on the old site currently. This can be done easily using vbscript and excel, or if you aren't very savvy at coding you could look at a piece of software called mozenda. There are a whole variety of methods that can be used to scrape data, all of them pretty easy to learn with a bit of research. Basically you write a script that will crawl your dom and extract the data (to xml works best in my experience)
Hope this helps.
I'm trying to make an App-wide media-upload which should have the possibility of being accessible from every controller/model.
I thought of on table media which holds record of all uploaded files, my schema looks like this:
id
controller //to keep the reference from which controller the file was uploaded
foreign_key //since files should be uploaded to specific records, I need this id
filename
extension
fullname
size
created
modified
I'm not sure what would be the best approach in doing this. I've thought of components, plugins and a behavior but still am unsure.
My App has many different controllers with different records.
For example it manages projects and should now be able to attach PDFs to specific projects from within the project-edit mask.
Since this is a feature needed by other controllers, too I want to write it application wide.
I'm pretty sure I need a helper to call the upload-function from within the masks.
May something like: echo $this->Media->uploadMask(); which provides me with an ready uploading-mask for the controller and id I'm editing at the moment.
But I don't know which route I should call for the upload. Something like /media/upload would be very good, but I'm not sure if this fits correctly into the MVC-approach.
Would it be better to call it from my specific controllers? Or is an AJAX-upload to just a normal controller/model like better?
What you are describing is a Behaviour, which is basically an object of methods that can apply to any model. For controllers there are also Components.
There are already a couple of established upload behaviours for CakePHP you should check out: Meio Upload which is good for basic image manipulation and also the CakePHP Media Plugin which is more advanced and more recently updated.
I'm trying to migrate all "content" pages on a website to DNN5 Pro.
So I just created all the pages in DNN, added HTML module to the ContentPane and copied and pasted the HTML content from old pages.
The problem is that most of the pages have bits of classic asp code which do some minor server-side tasks - for example, populate tables with prices fetched from DB, pre-select user's country based on his IP address, do some basic dates calculations, etc.
Obviously, this code won't work in DNN.
If I had to migrate to PHP, I'd just rewrite these bits of code from classic ASP to PHP, then assign values from PHP to smarty and then would use them in templates.
But as DNN has a completely different architecture, I can't see how similar approach can be used.
Token replacement feature in HTML module looks like what I need, but it allows to "map" only tokens provided by DNN.
So, maybe anyone had similar issue with DNN and/or knows how this should be done.
It seems like you are attempting to subvert the entire point of DotNetNuke. While certainly there are a variety of hacky ways you could try to make this work just like the php site, it's a terrible idea to do so.
Instead, you need to evaluate each of the dynamic sections of the php site and find or create a DotNetNuke module that will replicate that functionality.
To make the initial conversion quicker, you can build modules you create using simple ASP style inline scripting but you should definitely use existing modules for things like displaying data in a grid.
You could write code directly in your skin file. Do some logic like:
<%If PortalSettings.ActiveTab.TabID = 33 Then
//code here of what you want
End If%>
Where 33 is the page id for the page you want to run custom code on. There are other ways to do this like creating skin objects, or creating custom modules, but this is probably the easiest thing to do. Just write code directly in you skin. Or make a copy of your skin for each page you need to do custom code for... again, more elegant ways but this will get'er done.
I'm doing a personal, just for fun, project that is using screen scraping to give me a System Tray notification in case another line on an HTML table is added, modified or deleted.
Having done this before I thought: well let's go with the regular expression thing and that's it, but being a curious person, made me think that there could be something else out there that could have another paradigm but be as simple to use.
I know about DOM and X-Path and all the xml'ish approaches. I'm looking for something outside the box, something that can even be defined in a set of rules so you can make a plugin system to aggregate various sites.
See Options for HTML Scraping
Here's an idea: assuming your main use case is getting a notification whenever an HTML file changes, why not use a standard diff tool and then loop through the changed lines, applying your rules?
Also, if this is a situation where you have access to the server and the files you're watching, you might be able to put everything under source control with CVS (or similar) and just watch for commits. If you want to use this approach for random sites on the web, just write a script that periodically downloads the html for the appropriate URLs and then commits it to source control and watch the diffs.
Not very practical, but outside the box.
If you can convert the source into valid XHTML/XML using something like SgmlReader or HtmlTidy then you could use XSLT. Simply create a XSL template for each site you wish to scrape.
