Hi All, Though we can create a custom field through Admin panel with some conditions. I require a custom field as URL on publish form but I want this field should  store only unique urls in database. Can anyone here please suggest that how can I achieve this. Thanks

You will need set of modifications or simple plugin.

Alright. Is there a plugin available of that kind ? That can create custom field to store unique Url. I searched the internet a lot but couldn't find it. Please help.

There is plugin like Attributes osclass plugin, but will not work like "unique urls", you would need custom mod for that.

Almost same feature is inbuilt with Admin. This is not my requirement, hope you understand. We have a function in helpers folder hValidate.php to validate URL. Could you please check if it does.
