Post subject: | scaleFormat() method doesn't handle class-method callbacks |
I'm using AXIS_FORMAT_CUSTOM to generate y-axis labels, and want to use a class' method, rather than an isolated function. Currently, this doesn't work. I've isolated the problem to pDraw::scaleFormat(), which performs a function_exists check on the callback function provided before executing it using call_user_func (see line 3134). I've managed to get by this by extending pImage and overriding scaleFormat, but this should be updated in the core, in my humble opinion The following would provide an adequate check for class methods: Code: if ( $Mode == AXIS_FORMAT_CUSTOM ) { if ( function_exists($Format) || is_array($Format) && method_exists($Format[0], $Format[1]) ) { return( call_user_func($Format,$Value) ); } } Cheers, Eric |
