Hobbyist_PHPer Posted May 16, 2012 Share Posted May 16, 2012 Hi, this is a bit of a PHP and a JQuery question, so I wasn't sure which forum to post it in, but here it is... I need a way to asynchronously change a jQuery variable with PHP when a condition becomes true, without user action. I have the following JQuery: <script src="http://code.jquery.com/jquery-latest.js"></script> <script> finished = false; $(document).ready(function() { setTimeout("Refresh()", 5000); }); if (!finished) { function Refresh() { location.reload(); }; } </script> Then I have the following PHP code accessing the MySQL database every time the page refreshes... Here's that code: <? $query = "SELECT * FROM TempAwaitingClients WHERE PSOID = '{$_SESSION['user_id']}'"; $result = mysql_query($query); $rowCounter = mysql_num_rows($result); if ($rowCounter > 0) { while ($row = mysql_fetch_assoc($result)) { // Condition is true, need to stop the page refreshes echo '<iframe id="audiblealert" name="audiblealert" height="0" width="0" src="telephone-ring-4.wav"></iframe>'; echo '<a href="" target="audiblealert">Mute Ringer</a>'; echo 'Phone Number: ' . $row['ClientPhoneNumber'] . '<br /> Purchased Time: ' . $row['ClientPurchasedMinutes'] . ' minutes<br />'; } } else { echo 'No Clients Yet.'; } ?> Anyone have an suggestions or help? EDIT: I forgot to mention, it's the JQuery variable "finished" that I need to set to TRUE Link to comment https://forums.phpfreaks.com/topic/262613-change-a-jquery-variable-with-php/ Share on other sites More sharing options...

Hobbyist_PHPer Posted May 16, 2012 Author Share Posted May 16, 2012 Here's the whole page, it's rather small... : <? session_start(); include 'includes/connection.inc'; ?> <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title></title> <script src="http://code.jquery.com/jquery-latest.js"></script> <script> finished = false; $(document).ready(function() { setTimeout("Refresh()", 5000); }); if (!finished) { function Refresh() { location.reload(); }; } </script> </head> <body> <div> <? $query = "SELECT * FROM TempAwaitingClients WHERE PSOID = '{$_SESSION['user_id']}'"; $result = mysql_query($query); $rowCounter = mysql_num_rows($result); if ($rowCounter > 0) { while ($row = mysql_fetch_assoc($result)) { ?> finished = true; <? // Condition is true, need to stop the page refreshes echo '<iframe id="audiblealert" name="audiblealert" height="0" width="0" src="telephone-ring-4.wav"></iframe>'; echo '<a href="" target="audiblealert">Mute Ringer</a>'; echo 'Phone Number: ' . $row['ClientPhoneNumber'] .

Hobbyist_PHPer Posted May 16, 2012 Author Share Posted May 16, 2012 Oh, I think I know what you're getting at... put the query up top and actually write the JQuery variable with the PHP inside of the function, right?
