Thank you for your help, this is the code I have inside the json.php the
connection to database is done in a separate file, I don't get the JSON
objects when I call this file in the ajax script.
<?php
$selectQuery = 'SELECT * FROM competitive_daily_volume';
$result = mysql_query($selectQuery);
$rows = array();
if($result){
while($row = mysql_fetch_assoc($result)){
$temp = array();
$temp[] = array("v"=> $row['Date']);
$temp[] = array("v"=> $row['UserId']);
$temp[] = array("v"=> $row['CementBrand']);
$temp[] = array("v"=> $row['VolumeBGLP']);
$temp[] = array("v"=> $row['Type']);
$rows[] = array("c"=> $temp);
}
}
$table = array();
$table['cols'] = array(
array("id"=>"A","label"=>"Date","type"=>"string"),
array("id"=>"B","label"=>"User","type"=>"string"),
array("id"=>"C","label"=>"Cement Brand","type"=>"string"),
array("id"=>"D","label"=>"Volume","type"=>"string"),
array("id"=>"E","label"=>"Type","type"=>"string")
);
$table['rows'] = $rows;
$jsonObj = json_encode($table);
echo $jsonObj;
?>
