php and JSON help!

[vegetaz]

I have a script for updating a database table. I need to return a JSON array and to update some tables with JQUERY. my php script:\[code\]$update = mysql_query("UPDATE PLD_SEARCHES SET STATUS = 1, TOTAL_RESULTS = ".$scrapper->getTotalResults().",RESULTS = $resultCounter WHERE ID = ".$searchId);$output = array("status"=>"COMPLETED","results"=>$resultCounter,"totalResults"=>$scrapper->getTotalResults());echo json_encode($output);\[/code\]jquery code:\[code\]$("button").live("click", function(event){ event.preventDefault(); $.getJSON("startsearch.php",{ searchId: $(this).val() }, function(data){ alert(data[0].status); });\[/code\]now ...the problem is that if i use \[code\]$.post("startsearch.php",{ searchId: $(this).val() }, function(data))\[/code\] the script gets executed and i get a nice alert with value undefined. if i add the parameter "json" the script doesn't get executed anymore. I tried to use getJSON but again the same problem.Anybody has any ideas? I am desperate...this has been bugging me for almost a week and I still haven't managed to solve it.
