Double quotes issue when pulling data from database

[Adem]

Hello,
I am writing the following text to the database with PDO
SKYHAWK 3,5" 4TB 256MB 5900RPM ST4000VX013

Text image in database with phpMyAdmin

I don’t use any filtering when writing or reading.
because this process is in admin panel

To edit the product, only the following text is displayed in the input type text field.
SKYHAWK 3,5

I don’t understand, it’s okay to show it in other places on the page, but why is there a problem in editing?
<input type="text" name="hdd_name" value="<?php echo $read['hdd_name']; ?>">

When you output dynamic values in a html context, you must always apply htmlentities() to the value so that any html entities in it won’t break the html markup -
value="<?php echo htmlentities($read['hdd_name'],ENT_QUOTES); ?>"

Now, it is necessary to make changes in a lot of files in a lot of inputs, this was a job that would take a lot of time.

I’m using ckeditor, do I need to use it here too?

Thank you
