I am new in Zend Framework and learning it. I want to upload image into my database and display that image in view page. I search lots of tutorial but no step by step guidance. Want a help. Thanks in advance.
You need to take a look on Zend_Form_Element_File in Zend documentation:
The File form element provides a mechanism for supplying file upload
fields to your form. It utilizes Zend_File_Transfer internally to
provide this functionality, and the FormFile view helper as also the
File decorator to display the form element. By default, it uses the
Http transfer adapter, which introspects the $_FILES array and allows
you to attach validators and filters. Validators and filters attached
to the form element are in turn attached to the transfer adapter.
Database side, you need to use a BLOB type to hold your image (I assume you're using MySQL).
However, note that best practices are to store the image path in the database instead of the image itself.
At last, there are tons of tutorials out there that explains precisely how to do what you're looking for, you just need to look for "file upload using zend element file" and you will find them!

I want to add a button to the system.header/left, which I already did. And when I click that button, I want a file picker popup to choose my CSV.
From the CSV content, I want to create space and pages.
I've browsed through the documents and tutorials, but I can't find anything alike.
Could you point a direction or steps for me? At least, point me to something relevant?.
Here's a short overview:
Your button will trigger a JavaScript.
That javaScript will open a dialog window containing the form elements allowing the file upload
The target of that form will be either a servlet or rest-endpoint
inside your plugin. Let's assume it's a servlet.
The servlet will
take the submitted file, split it using the defined separator and
create the page structure using the confluence API calls.
And forward to the start page of your new Space.
I'd suggest that you start with the servlet.
Provide a couple of lines of test data, to check if your code creates the page structure as expected.
Once this works, add the file handling part (from a dedicated html) and pass the data to your existing function.
Now, you have the backend and the frontend, so rendering the dialog when your button is clicked, is pretty straight forward.
Make sure to display the button only if the current user has the right to create a space.

I am building a project with Django 2.2.4 and PostgreSQL 11.4. I am using JSON database fields to store data in JSON arrays.
In my app users create documents using "rich text editor" that provides standard text/image features already.
I also want to enable users create the document to drag and drop form inputs into the body of the document so that once the document is "published" other users can view the document an add input values to these fields before submitting and saving the document again.
Now, I'm trying to figure out conceptually the most efficient way to approach this.
I thought the first step would be to use an abstracted rich text editor which separates the document structure from the HTML, e.g. CKEditor or Quill; if I was to serialise the document with form inputs included I could in theory store templates in one JSONField and inputs in another.
This list is a really useful overview of various editors, but despite having read a lot of documentation it's not clear if this approach would be either correct or actually possible.
Does anyone have any similar experiences?
Pretty sure this isn't possible unfortunately.
Could you elaborate on what you're trying to do with this?
Disclaimer: I am not an AEM developer, I'm filling in on a project, so forgive me if I am missing the obvious.
I have a page template that will contain a component that will show a list of locations, this template will be used for many city pages.
I'm trying to figure out the best way to get the content into the JCR or read it using a script from a CSV file.
Are there any out-of-the box or open source components out there that can accomplish this?
There are several ways to accomplish your task. The easy part should be rendering the information. You would usually implement a Sling model or a class extending WCMUse, access the repository via the Sling API and render the resources via Adobe HTL. The resources being rendered have to be selected of course: write a Servlet which provides an interface to the resources and use an adequate form element in the component's dialog.
The hard part consists of two parts:
Perhaps just upload the file, process the data and by using the Sling API for resource creation, you can write the data into the repo. You could also utilise the DAM for such tasks and implement a workflow.
Depending on the amount of data, you might want to save the data as JSON string as property of a node.
I hoped that helped a bit.
"Are there any out-of-the box or open source components out there that can accomplish this?"
Simple answer: NO
While there are several libraries that can help you parse CSV files, storing it in JCR depends completely on your project. The structure can be arbitrary or (in a brute force way) you can just store the CSV file as data in your node but that may not be useful.
Depending on how you plan to use the data, it may be useful and optimal to save it in a relevant hierarchy for your project.
I have this problem:
I want to make an interface where the user can drag and drop file uploads. Filepicker.io provides an easy solution to this in the form of filepicker.makeDropPane. However, this feature does not support parallel uploads without the callbacks getting confused.
So I would like to write my own drag/drop interface using standard html5 listeners, and make a direct api upload call to filepicker.io with the actual file data in string form. This way I can write the management of parallel uploads on my own.
Does filepicker.io have an api call that would allow me to do this? I only see these two things:
1) File selection modal
2) Auto drag-drop features
I don't see a way to simply upload a file directly from file data.
What can I do?
You should make use of the filepicker.store() command, which accepts a DOM file object. For example:
var input = document.getElementById("store-input");
filepicker.store(input, function(FPFile){/*your code here*/});

In my app I want to retrieve data from database and add it to an excelsheet.
The Database's data are in string and BLOB format. I have retrieve the data and added to excel sheet using the frameworks:
https://github.com/andreac/RSSheet
The problem is that I want to add image to the worksheet too.
If any one has any idea about this please help me.
The RSSheet library does not currently support adding graphics to the sheet. You'll need to do this on the server side unless you expand the RSCell class to support this.
Depending on your backend this can be done easily. In PHP I used the PHPExcel library.
