I am trying to make a blog using nodejs and mongodb. I want to store all my blog contents in mongodb and load it from there. What would be the best way to do so?
I was wondering how wordpress stores the blog content and displays them in a proper formatted way.
Do I need to bisect the blog contents and then make a html structure out of the contents and save the entire thing in the database or is there any other way to keep the texts formatted and make html structure after fetching the contents?
Don't be hating for a noob question. :)
You can see how WordPress does this by looking at the source of wp_update_post(). Essentially, it escapes all special characters, runs wp_slash(), and saves the post data in a longtext database field.

Of course, I have read this question and know it is impossible in a simple way:
How to set a value to a file input in HTML?
However, I need it. For example, assume there is a User model that can have an attached file called avatar. Then, a user uploads their avatar image and tries to save what they typed in, but it has led to a validation error. Now, they expect the uploaded image to be there just like other text/number/date/etc. fields they filled. However, it is not done.
I could temporarily put the image into DB to show it again after the validation error, but do I really have to save it in DB? Is there any way that only uses browser and server RAM like a text field?

Welcome, all
I would like to create a small web application, which needs to scrape data from another website and save the results to a database.
So, currently, I have Laravel 8 installed on my local windows machine, and I made a connection to the database, where I have "items" in the table that I need to save the data in
And the data may be changed from another website so I need this change in the database as well,
and need to scrape many items from another website so I need to know id or something else to distinguish one item from another
Now, the question is, what is the best way to do this? I've tried some tutorials but I haven't.
You can use a package Goutte or domcrawler, first you need to do a request of a url for that you can use GuzzleHttp or get the portion of html content and filter it and then save all this data on a table of your database.
You can read more information about those libraries.
Another library that is more customizable is domcrawler Dom_Crawler,
Goutte

Recently I'm building a website where I need data of all car types and models, such an example with the data type is sellanycar.com.
I need all the data from 'Select Make' and corresponding 'Select Model' dropdowns:
The code of any language is acceptable but javaScript/jQuery or Python is preferable and the data can be of any format e.g. JSON or XLXS, etc.
A) In JS/Node, you can use Pupeteer to scrape pages, and Cheerio, do extract what you want JQuery-style.
B) You could use a scraping tool such as Screaming Frog, to do the same, and set upp XPATH or REGEX extractions. I wrote a small piece on how to set up custom regex extractions, which might help, should you choose this option.

I have a MySQL db that is supposed to store shift details like start time, employee, breaks, nr. of items processed etc. to then analyze this data with MS PowerBI.
The employees are supposed to enter the data themselves after their shift and be separated from the data (not see or change it afterwards).
How should I set up the form the employees enter their data into? Should I make a website with a form on it or should I make a diy program that connects to the db?
I am quite new to all of this so I’m trying to find the best way to complete this.
Thank you very much in advance!
You already have a best guess. Yes, create a website which allows the employee to enter the details, grab the info with a back end application (php/java/kotlin/nodejs/python ... e.t.c), and do not develop a page that retrieve data to the website for the employees.
Afterwards, you can export your data to your desired application (you might need to develop something for smooth data transfer as well)

I am currently working on a project and the end goal is for someone to put in the part specification and then the part number and data comes out. I need help to get my html page to search my excel spreadsheet with the specifications and then spit out the part number and price and data. Here's where my inspiration is coming from http://www.lesker.com/newweb/flanges/nipple_builder.cfm
If anyone can help me with a code to search my spreadsheet I would greatly appreciate it, I'm a bit of a novice
You definitely need a dynamic approach to handle this goal. You can not get HTML to Excel work together and the best alternative is to use PHP+MySQL, upload your database to your web server and query it using php. You will have great difficulties if you use only HTML when it comes to update your items in the list.
