noamkrief Posted November 1, 2007 Share Posted November 1, 2007 I have this ajax script that works with php mysql. When mysql gets 0 results, I want the page redirected. I find this impossible to do. Please if you could be thoughrough in your explination if you have my answer, I'm very new with ajax. html page: <head> <script language=Javascript> function Inint_AJAX() { try { return new ActiveXObject("Msxml2.XMLHTTP"); } catch(e) {} //IE try { return new ActiveXObject("Microsoft.XMLHTTP"); } catch(e) {} //IE try { return new XMLHttpRequest(); } catch(e) {} //Native Javascript alert("XMLHttpRequest not supported"); return null; }; function dochange(src, val) { var req = Inint_AJAX(); req.onreadystatechange = function () { if (req.readyState==3) { document.getElementById('loading').innerHTML='<font id=loading>loading page...</font>'; } if (req.readyState==4) { document.getElementById('loading').innerHTML=''; if (req.status==200) { try { document.getElementById(src).innerHTML=req.responseText; //retuen value if (src == 'grab'){ fireMyPopup() } } catch(e) { //alert("Exception for " + src); } } } }; req.open("GET", "./connector.php?data1="+src+"&val="+val); //make connection req.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=iso-8859-1"); // set Header req.send(null); //send value } </head> Now I have the connection.php page which looks something like this: <?php // connect to db etc... $sql = mysql_query("some query"); if (mysql_num_rows($sql) > 0) { echo 'some text into the main index page'; } else { //need to redirect the index.html page to a different page... have tried doing header('location: ./page.html'); obviously that did not work... } ?> I cannot make the connector.php page force a browser redirection.... Any help would be greatly appreciated. thanks Quote Link to comment Share on other sites More sharing options...
deadimp Posted November 2, 2007 Share Posted November 2, 2007 Make a block in Javascript that handles a certain flag returned by your AJAX request, and then either change the document location (better) or create a meta-refresh if you're paranoid (worse). Example: <ajax.php> $data=array('good'=>false, 'list'=>array()); if (mysql_numrows($res)) { $data['good']=true; //... Insert you data or whatever in the list } echo json_encode($data); <stuff.js> function ajax_handle(str) { //... Proper states, etc eval("var data="+str); //Ghetto JSON decode if (data.good) { //... Handle all the data } else document.location="redirect.php"; } That's the basic jist of it. Quote Link to comment Share on other sites More sharing options...
