cjkeane Posted April 8, 2011 Share Posted April 8, 2011 hi everyone. i have content in an iframe. when a delete link in a form, is clicked. i need the parent window to be refreshed. i currently have the code below. it seems to refresh the page but not the content. for example, if i manually refresh the page, the data will display, but an automatic refresh through javascript doesn't refresh the content in the iframe. i'd appreaciate the assistance. thanks. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <link href="styles.css" rel="stylesheet" type="text/css" /> <script type="text/javascript"> function refresh_parent(){ parent.location.reload(); } </script> </head> <body> <form method="post" enctype="multipart/form-data"> <table width="350" border="0" cellpadding="1" cellspacing="1" class="box"> <tr> <td width="246"> <input type="hidden" name="MAX_FILE_SIZE" value="20000000"> <input name="userfile" type="file" id="userfile"> </td> <td width="80"><input name="upload" type="submit" class="box" id="upload" value=" Upload " onclick="refresh_parent()"></td> </tr> </table> </form> <table> <tr> <th align="left" width="300px">Filename: </th> <th align="left" width="200px">Type: </th> <th align="left" width="60px">Size: </th> </tr> <?php if (mysql_num_rows($filelist) > 0) { while ($f = mysql_fetch_array($filelist)) { //GET FILE SIZE $fileSize = $f['size']; if ($fileSize>999999){ //IF GREATER THAN 999KB, DISPLAY AS MB $theDiv = $fileSize / 1000000; $fileSize = round($theDiv, 1)."

Adam Posted April 11, 2011 Share Posted April 11, 2011 It may be that the browser is caching the page, and refreshing the parent doesn't refresh the frame's cache. What you could do to guarantee the cache-bust, is add a random number on to the src of the iframe, for example: <iframe src="iframe-page.php?rid=<?php echo rand(); ?>"></iframe> To the browser that will be a different page, and cache separately.
