Problem: It seems like I have hit some kind of limit on the number of custom fields I can add to a field group. If I try to add another field, it does not save correctly. If I delete another field, then I can add another field. Is there a maximum number of fields? How can I increase this setting?
Solution: Ask your hosting company to help increase a PHP configuration called "MaxInputVars". Yours is currently set at 1000, so try increasing that configuration value to be 3000.
Problem: I would like to use a conditional to test if a numeric custom field value is empty or greater than zero. If so, I would like to display the value. If not, I would like to display nothing.
Solution: You could use "AND" in the comparison to test both ne '' and ne '0', like so:
{!{wpv-conditional if="( ($(wpcf-listing-price) ne '' ) AND ($(wpcf-listing-price) ne '0' ))"}!}PRICE: [types field='listing-price' format='FIELD_VALUE'][/types]{!{/wpv-conditional}!}
Or testing if the value is greater than zero might be a simpler solution:
