Hi Julia,
Please Request/feedback forum for suggesting plugins.

Also, We do not suggest filtering urls as it will need regular expression and that is not good for performance.

If you want to limit the length of data a user can enter, I can certainly provide code for that. Please let me know if that is what you need.

Here is the code for that

/**
 * Limit the allowed no. of characters for xprofile field.
 *
 * @param bool                   $validated is validated?
 * @param string|array           $values value(s).
 * @param BP_XProfile_Field_Type $field field object.
 *
 * @return bool
 */
function buddydev_limit_xpfield_length( $validated, $values, $field ) {
	$allowed_len = 0;

	if ( $field instanceof BP_XProfile_Field_Type_Textarea ) {
		$allowed_len = 500; // how many chars.
	} elseif ( $field instanceof BP_XProfile_Field_Type_Textbox ) {
		$allowed_len = 100; 
	}

	if ( $allowed_len ) {
		$validated = strlen( $values ) < $allowed_len;
	}

	return $validated;
}

add_filter( 'bp_xprofile_field_type_is_valid', 'buddydev_limit_xpfield_length', 10, 3 );

It will not show any specific error, just a generic error. Please make sure to specify the length in description.

Hi Julia,
That was expected. Specially on the edit page. BuddyPress doe snot give any specific error on the profile edit page. That’s why I asked you to put a message in the description.

The better and accessible way will need too much code for a simple task like this.

2. sure, You can use any of the available javascript plugins to do that. I don’t have enough time to find a library and post the code. I will leave it upto you to find and use it.

You are welcome.
