find duplicate addresses in database, stop users entering them early?

Question

How do I find duplicate addresses in a database, or better stop people already when filling in the form ? I guess the earlier the better?

Is there any good way of abstra

Answer 1

As google fetch suggesions for search you can search database address fields

First, let’s create an index.htm(l) file:

    
    

    
        
        
        
        
        
        
        
        
        

    
    

    
        


            

                
Try it yourself
                

            
        
    

Now we will create a city.php file which will aggregate our query to MySQL DB and give response as JSON. Here is the code:

 $row['city'].', '.$row['zip'],
            'value' => $row['city'],
        );
    }
    //RETURN JSON ARRAY
    echo json_encode ($array);
}

?>

and then prevent saving them into database if found duplicate in table column

And for your addressexists.php code:
