Return value of manage() in plugin.

Postby rmichael » Thu May 01, 2008 7:57 pm

What is the meaning of the return value of manage() in a plugin? On what basis should I be deciding to return true or false?

The sample plugin in the OJS Technical Reference seems to return true if the verb was "managed" (more accurately, it returns true if one of the case statement switches matches, not based on the success or failure of the respective action); while the webFeed plugin is returns false if a verb matches the case statement (again, that's regardless of the success or failure of the get/set verb handling itself).

Aren't these opposing semantics? Have I misunderstood something? How will OJS interpret my return value?

Hi Richard,

If the manage() function returns true, it indicates to the handler class (pages/manager/ that the plugin has already provided the user with feedback, i.e. a redirect or a page display. If the manage() function returns false, the PluginHandler will take responsibility for redirecting the user somewhere else.
