Use saved variable in cookie with php

Over the past two weeks, I have been working on storing the page id in cookies and then retrieving it on another page.

Finally, I solved it, but now I have another problem, I want to use this id (the one that I saved in the cookie and get it) in my php code.

I know that javascript is client side code and php is server side code, but I have to do this. Please help me with this.

This is my javascript code that works great, and I get the saved id with this line "+ value.favoriteid +"

<script> /* * Create cookie with name and value. * In your case the value will be a json array. */ function createCookie(name, value, days) { var expires = '', date = new Date(); if (days) { date.setTime(date.getTime() + (days * 24 * 60 * 60 * 1000)); expires = '; expires=' + date.toGMTString(); } document.cookie = name + '=' + value + expires + '; path=/'; } /* * Read cookie by name. * In your case the return value will be a json array with list of pages saved. */ function readCookie(name) { var nameEQ = name + '=', allCookies = document.cookie.split(';'), i, cookie; for (i = 0; i < allCookies.length; i += 1) { cookie = allCookies[i]; while (cookie.charAt(0) === ' ') { cookie = cookie.substring(1, cookie.length); } if (cookie.indexOf(nameEQ) === 0) { return cookie.substring(nameEQ.length, cookie.length); } } return null; } function eraseCookie(name) { createCookie(name,"",-1); } var faves = new Array(); $(function(){ var favID; var query = window.location.search.substring(1); var vars = query.split("&"); for (var i=0;i<vars.length;i++) { var pair = vars[i].split("="); var favID = (pair[0]=='ID' ? pair[1] :1) //alert(favID); } $(document.body).on('click','#addTofav',function(){ var fav = {'favoriteid':favID}; faves.push(fav); var stringified = JSON.stringify(faves); createCookie('favespages', stringified); location.reload(); }); var myfaves = JSON.parse(readCookie('favespages')); if(myfaves){ faves = myfaves; } else { faves = new Array(); } $.each(myfaves,function(index,value){ var element = '<li class="'+index+'"><h4>'+value.favoriteid+'</h4> '; $('#appendfavs').append(element); }); }); </script>

Read the cookie on the php side, this is easiest after you set them under js .

Any cookies sent to you from the client will be automatically included in the $ _COOKIE auto-global array if theorder variable contains "C". If you want to assign multiple values ​​to a single cookie, simply add [] to the cookie name. Regular PHP_ variables from cookies can be created depending on register_globals.

Here php are some examples:

 <?php echo $_COOKIE["your cookie name"]; ?> <?php print_r($_COOKIE); ?>

Relying on them is not recommended, as this feature is often disabled for security reasons.

If you already managed to save the cookie in javascript, then there is no problem extracting it in PHP, just use $_COOKIE["COKKIE_NAME"] (where you, of course, change COOKIE_NAME to the name of the cookie you saved in JS) ..

See http://php.net/manual/en/features.cookies.php for more examples.
