Validate Title Field to Allow Only Numbers

[waheed]

Hi, Coming from a background of WP I'm very new to PW (this is my very first project), but so far it has been very easy to learn. Currently I'm developing an intranet webapp to my school. I would like the "school grades" to be added as pages without any field in it, except "title" and "name". I would like the "title" to hold only numbers (optionally min:1 & max:10) and non-repeating (pages with same title cannot be added). Is this possible to be done, if so how? (Pls, try not to guide me towards a premium module, we run on a small budget)

On the edit page of the title field, go to input tab, open the pattern field, there you can add a regular expression pattern ( [-+]?[0-9]*[.,]?[0-9]+ (for numbers with or without decimals)).

Or you can add a hook and check the title before saving. https://processwire.com/api/hooks/

Thanks @fbg13.

But won't this affect the title field of other pages as well.

I think I'll go with hooks. It'll give me more control, I guess.

You can do it per template, by going to the template edit page and click the title field.

Everything you set there is gonna affect that template only.
