If you want to do it  what I think you are trying right now  then replace this line   lt input type  submit   lt a href     onclick  history back     gt  Back  lt  a gt    with this   lt button type  button  onclick  history back     gt Back lt  button gt    If you don t want to rely on JavaScript then you could get the HTTP REFERER variable an then provide it in a link like this    lt a href   lt  php echo   SERVER  HTTP REFERER     gt   gt Back lt  a gt

You need to tell the browser you are using javascript    lt a href  javascript history back 1   gt Back lt  a gt     Also  your input element seems out of place in your code

lt input type  submit   lt a href     onclick  history back     gt  Back  lt  a gt    Is invalid HTML due to  the unclosed input element    lt a href     onclick  history back 1    gt  Back  lt  a gt    is enough
