How to set a session variable when clicking a a link

Question

I have the following problem    I want to set a session variable when clicking on a normal link like    lt a href  home  name  home  gt home lt  a gt    My research seems to point out that it is not possible for PHP to catch up with the click event in a such a way that it would set a session variable   I believe it is possible with Ajax  but how  And what would my link look like  Setting the session variable should look like       SESSION  link     home    So in short  When clicking on a link in HTML  a session variable must be set  HOW am i going to do that   PS  I m not quite familiar with Ajax  but I ll catch up   EDIT  The links will refer to the same page  also i want to avoid urls like  home php link X   If it isn t possible to do it any other way  too bad  But I ll hope there is a solution  Important  the name of the link will be the value of   SESSION  link

session start        if isset   SESSION  current                 SESSION  oldlink     SESSION  current         else             SESSION  oldlink    no previous page               SESSION  current     SERVER  PHP SELF      Maybe this is what you re looking for  It will remember the old link page you re coming from  within your website    Put that piece on top of each page   If you want to make it  refresh proof  you can add another check      if isset   SESSION  current     amp  amp    SESSION  current      SERVER  PHP SELF      This will make the page not remember itself   UPDATE  Almost the same as  Brandon though    Just use a php variable  I know this looks like a security risk  but when done correct it isn t      lt a href  home php a register  gt Register Now  lt  a gt    PHP     if isset   GET  a      you can validate the link here           SESSION  link     GET  a         Why even store the GET in a session  Just use it  Please tell me why you do not want to use GET     Validate for more security  I maybe can help you with a better script

I had the same problem - i wanted to pass a parameter to another page by clicking a hyperlink and get the value to go to the next page  without using GET because the parameter is stored in the URL    to those who don t understand why you would want to do this the answer is you dont want the user to see sensitive information or you dont want someone editing the GET   well after scouring the internet it seemed it wasnt possible to make a normal hyperlink using the POST method   And then i had a eureka moment     why not just use CSS to make the submit button look like a normal hyperlink       and put the value i want to pass in a hidden field  i tried it and it works  you can see an exaple here http   paulyouthed com test css-button-that-looks-like-hyperlink php  the basic code for the form is        lt form enctype  multipart form-data  action  page-to-pass-to php  method  post  gt                           lt input type  hidden  name  post-variable-name  value  value-you-want-pass   gt                           lt input type  submit  name  whatever  value  text-to-display  id  hyperlink-style-button   gt                   lt  form gt    the basic css is        hyperlink-style-button        background none        border 0        color  666        text-decoration underline              hyperlink-style-button hover        background none        border 0        color  666        text-decoration none        cursor pointer        cursor hand

Is your link to another web page  If so  perhaps you could put the variable in the query string and set the session variable when the page being linked to is loaded   So the link looks like this    lt a href  home php variable value  name  home  gt home lt  a gt    And the homge page would parse the query string and set the session variable
