问题
What I want to do is I want to post two datas in one table but I don't know if it's possible or not. Is there any way that a column can hadle two datas or more at once?
Here is the modal
Like for example I have two monitors that I want for my unit. But from what I can see from the database only the first field gets recorded not the added field. As you can see I have a little function where I can add and delete fields in categories where items can be multiple or not.
Here is my table that I want to send the datas in

You should really look into database normalization.
With your current table structure, there's no efficient way to do what you need (because you only have one field for storing each type of component.
A workaround would be to convert each field that could potentially hold multiple user selections to a JSON type and store them there. (all it takes would be to build a $monitors array and then convert it to json (with json_encode($monitors) prior to inserting. This, while feasible, has some drawbacks in terms of efficiency and indexability/searchability
what you really need is, like I said earlier, normalizing your tables.
You should have a "pivot" table (let's call it "assemblies") and separate component tables (call them what you want, but it could be "monitors", "cpus", "memory" etc). When assembling a new device, you'd create a new "assembly" and insert the components in their respective table with a reference to the master "assemblies" table By doing this, you could have a single assembly referencing multiple entries in the "monitors" table because this structure allows establishing "one-to-many" relationships
I strongly suggest you get your feet wet with normalization. Wikipedia could be a good starting point HERE

You can store json object in json datatype and application level you can access
