magento 1.9 - how to check if product has price by external script -


right working on following task:

i have text-file, contains prices magento-shop, imported every night.

there script running in background, comparing file soap magento product catalog, if articles existing price in file going imported. script splitting file chunks , createds chunks prices of products existing.

the import follows taking pretty long time, because there lost of articles.

so optimize script no check, if articles exist articles have price , if price going imported different or not. if price shlud gettung imported, if not, not import.

i didn´t wrote basic script, give me idea how code has to check if article has price?

thanks in advance ideas.

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
