I want to know if it is physically possible to make this change to move step 3 in step 1 without having any bugs and that it works perfectly.

Category and subcategory selection, insert title, insert description, price insertion. Then insert the attributes created by the custom fields. Stop. STEP 2 = original. Step 3 = name, location, email, phone, address, zip code, and all the personal data that were in step 1.

I want to know if you can make this change without having any type of bug later. For example, I insert an ad, I click on the category auto, and automatically at the bottom I charge the custom fields of the car that I have previously created. Or do I select the apartment category for sale? In automatic I load the custom fields of the selected category, all this in step 1, then you go to 2 and then to 3.

Thank you

I had seen this thread but I don't want everything in step 1. I always want all 3 steps. It's not possible?
 

@annunci
It is, but we have no such code and you need to develop it by yourself.

I contacted him and is working for several days, initially he thought he succeeded then after he encountered many bugs and now is fixing. He tells me He'il succeed. But he told me it's complex. I wanted to know from you if it is true and above all I wanted to know if the developer is good, will manage to do everything without bugs?

This you write is no language, nice professionalism that you have, congratulations. You take the game of your customers
 

I managed to do what I asked. I brought step 3 in step 1. Look at the result on my www.annuncigratuiti.com page insert an ad and select far category which is where I entered the additional fields for now Custom fields load According to the category you selected


I wanted to understand one thing, but if you updated the theme in the future I have to remake the procedure I did to move it back to step 3 in the 1? Check if it's done well so I give you the modified files and the next updates you do so directly. Because 99% of the online classifieds sites has this order here: first category then title then description then price and then additional fields and additional information then pictures and then eventually the personal contact details. And it's much more correct so, trust me

Update will wipe your changes.
You may try child theme functionality of osclass to avoid this.
