Hi.
For the second question look here:
https://forums.osclass.org/development/new-type-of-custom-field-suggestion-number-input-and-interval-filter/msg159215/#msg159215

This is not imposing the user to insert numbers in the input fields as the db column is text not numeric.

Thanks i will look.

what about this at least?
<input id="number" type="number">


I don't know how to implement
 each custom fields have have Identifier name how can I test during posting an ad  ?

if custom fields field Identifier name  == "..."  {<input id="number" type="number">}

I never tested via type="number" because the field in DB is text so...
Anyway my solution workes ok. If the user inputs a nonnumeric value he loses, "author" or "seeker".

with custom fields enhancer plugin I got this error in item php

Warning: array_key_exists(): The first argument should be either a string or an integer in /Applications/AMPPS/www/new/oc-content/plugins/custom_field_enhancer/functions.php on line 913


when I had applied your code for item no2

any way thanks for sharing.

 My solution is a core code changer.... it ads a new type of custom field... so I gues it's not compatible with the plugins for custom fields.
EDIT
Try to use date interval as a custom field and see if the same warning occurs.
It's a warning not error, and that plugin is a paid one so you can't share the code.... maybe the developer could help you.
