This is an EE2 rewrite of the EE1 Entry Category Count plugin originally released by Erik Reagan. Credits for the original idea goes to him. I simply needed it for EE2.

Returns the number of categories for a given entry

Examples

Simple

{exp:jco_entry_catcount entry_id="3"}{nbrcategories}{/exp:jco_entry_catcount}
{exp:jco_entry_catcount entry_id="{entry_id}"}{nbrcategories}{/exp:jco_entry_catcount}

Limited to category group(s)

{exp:jco_entry_catcount entry_id="3" category_group_id="1"}{nbrcategories}{/exp:jco_entry_catcount}
{exp:jco_entry_catcount entry_id="3" category_group_id="1|2"}{nbrcategories}{/exp:jco_entry_catcount}
{exp:jco_entry_catcount entry_id="3" category_group_id="not 2"}{nbrcategories}{/exp:jco_entry_catcount}

Using Conditionals

{exp:jco_entry_catcount entry_id="{entry_id}"}
 {if nbrcategories == 0}
  No categories assigned to this entry
 {/if}
{/exp:jco_entry_catcount}

{exp:jco_entry_catcount entry_id="{entry_id}"}
 {if nbrcategories > 0}
  Multiple categories assigned to this entry
 {/if}
{/exp:jco_entry_catcount}

Parameters

entry_id=“1” : Mandatory
The id for the entry that you want to output the number of categories for

category_group_id=“1”: Optional
The id of the category group you want to limit the query to
You can use piped list: category_group_id=“1|2”
