i have code in php , trying insert data mysql face problem number of elements in type definition string doesn't match number of bind variables

your type string in statement doesn't have enough type specifiers in it.

bind_param("sss",$regvalue1,$regvalue2,$regvalue3,$regvalue4,$regvalue5,$regvalue6,$regvalue7); 

says have type "sss" corresponds 3 of 7 variables specified. need add types rest.

from documentation:

var1

the number of variables , length of string types must match parameters in statement.
