php - Session information not maintained while AJAX requests -
i creating session while rendering page. after calling ajax page every 4 seconds. ajax page doesnt gettign session information.
what may reason. whether ajax requests dont maintain session information?
code:
normal html
<body onload="timerint(11)"> <div style="display:none;"> <button id="prev"><<</button> <button id="next">>></button> </div> <div class="anyclass"> <ul id="news-ul"> <?php include('render_latest.php'); ?> </ul> </div> </body> render_latest.php
<?php session_start(); $con = mysql_connect("localhost","root","root"); mysql_select_db("test_db", $con); $i=1; $lastresult=mysql_query("select max(epoch) latestepoch list_data"); while($row = mysql_fetch_array($lastresult)) { //$_session['lastepoch'] = $row['latestepoch'] ; $_session['lastepoch']=12345; } $result=mysql_query("select * list_data order epoch desc limit 4 "); while($row = mysql_fetch_array($result)) { echo '<li>'; echo $row['list_item'] . '<br/>' ; echo $row['epoch'] . '<br/>'; echo $_session['lastepoch']; echo '</li>'; } ?> ajax page
<?php session_start(); $t=$_session['lastepoch']; $con = mysql_connect("localhost","root","root"); mysql_select_db("test_db", $con); $result=mysql_query("select * list_data order epoch desc limit 1 "); while($row = mysql_fetch_array($result)) { echo '<li>'; echo $t; echo $row['list_item'] ; echo '</li>'; } ?>
the session data stored in cookies browsers, or can use query string of request pass parameters. eg: .../render_latest.php?lastepoch=123456 , read lastepoch parameter in php.
or can use html5 client-side storage in modern browsers.
