ItemManager 2.0

[Bigin]

Yes of course I can do that, but this is just what I'm trying to avoid: inventing the wheel again.

Hmm, why don't you publish the password for the admin on your website and the job is done, so you don't have to write a line of code? ;-)

If there's already everything place for admins to create new items via forms then how it can be that hard to create similar page that would be accessbile to anyone?

As I have already written, it is relatively simple to adopt the approach of backend methods as long as you are confident in what you are doing, and know how it works.

What would be the least overlapping method?
Could I create another Manager class which doesn't include admin checks and similar things that are now in Manager class?

I don't understand the point of your approach, sorry... that sounds strange, somehow comparable with :-)



To make this adjustments you need to be familiar with ItemManager core. This is completely unnecessary, there is a comfortable API to do these things quicker and better. For these customizations you will need 10 times longer than writing your own processor - so much for staying "inventing the wheel again".

Just try ImForms and see how easy it is to use that plugin for this purpose.

Step 1:
Download the latest version of ItemManager and ImForms and install/update it.
Open /plugins/im_forms/inc/custom.config.php file, and modify formProcessors variable as follows: 


PHP Code:

$config->formProcessors = array(
    'EmailTransmitter' => 'EmailTransmitter',
    // Note: Key and value should be equal, there is an issue for the moment
    'FormProcessor' => 'FormProcessor'
); 


Next, download an example form processors from https://github.com/bigin/FormProcessor, and extract the archive into /plugins/im_forms/module/ folder (Note, folder, file and the class, must have the same name FormProcessor, see EmailTransmitter modules, for example).

Step 2:

Go to the IM menu and select imforms category click "ADD NEW".
Enter name "itemform".
Check "Enabled".
Enter exactly this value , in the field Form Data.
Then, click "Save".

Step 3:
Go to Pages > ImForms menu and check if there is a new test form itemforms.
If so, open a page on which the form should be shown and enter this placeholder [[imforms itemform]] in editor, then save.
Open that page in the browser, a test form should now appears there.

Step 4:
Now, look at your processor file in the /plugins/im_forms/module/FormProcessor/FormProcessor.php directory. Especially the methods checkUserInput() and save() - there you can start to extend your application. All the form entries can be found in the $this->input->post variable. You can display it by using the Util::preformat($this->input->post) method.
A tip: If you remove the AjaxBlock and DelayBlock in your itemform, you can see the output directly from the processor, use echo or var_dump() for this.
