i want alert PHP MySql after insert notification alert in one page
Could you please describe more exactly what is that you actually want ? I don’t want to come forward as aggressive, but that sentence gives us nothing to work with. Maybe a more detailed explanation of what you want and some code that you have already written would be helpful.
Pretty sure OP is referring to “Flash Messages”. OP, there is your Keyword phrase to lookup.
Or you could just use the lack of a failure message to indicate successful completion.
