JavaScript code:
<script type="text/javascript">
$("#test").click(function() {
getQuerystring(this);
return false;
});
function getQuerystring(el) {
console.log(el.href);
var getUrlParameter = function(sParam) {
var sPageURL = el.href.split('?')[1],
sURLVariables = sPageURL.split('&'),
sParameterName;
for (var i = 0; i < sURLVariables.length; i++) {
sParameterName = sURLVariables[i].split('=');
if (sParameterName[0] === sParam) {
return sParameterName[1] === undefined ? true : decodeURIComponent(sParameterName[1]);
}
}
};
var blog = getUrlParameter('c');
//document.getElementById('detail').innerHTML = blog;
document.cookie = "blog = " + blog;
}
</script>
html code
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="border: dashed; size: auto;">
<a name="divtest" href="#detail?c=active" id="test">testing</a>
</div>
<div id="detail" style="border: 2px; size: auto;">
<?php
$chk = $_COOKIE['blog'];
echo $chk;
?>
</div>
The JavaScript code should set the cookie, and then php get the values saved in the cookie. I basically want to send value from JavaScript to php on the same page. but it seems to be an error "Notice: Undefined index: blog in C:\wamp64\www\test\ajax.php on line 40". I have searched a lot but didn't find the proper solution. How can I correct my code?
Jquery ajax:
$.ajax({
url: "path_to_ajax_file",
type: "post",
success: function (response) {
document.getElementById(“result”);
}
});
HTML code:
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="border: dashed; size: auto;">
<a name="divtest" href="#detail?c=active" id="test">testing</a>
</div>
<div id="detail" style="border: 2px; size: auto;">
<span id=“result”></span>
</div>
Ajax code:
echo $_COOKIES[“blog”];
So first create HTML structure then call ajax in javascript by jquery and last create ajax file.
