terrid Posted August 16, 2010 Share Posted August 16, 2010 Hi all I have an array and within that array that list categories. Each category has a sub category. I am trying to output in JSON and my problem is this: I am looping through each category and displaying the results. As the category has sub categories I am then looping through them and displaying the sub categories. This works fine, but my JSON is not valid because of a single comma: { "config":{ "logo":"uploads\/global_config\/scaled_", "deliveryCost":19.99, "showPrice":"true" } }, "range":[ { "title":"Classic", "doors":[ { "id":19, "title":"Rembrandt" }, { "id":66, "title":"Picasso" }, { "title":"Heritage", "doors":[ { "id":29, "title":"Broadway" }, { "id":30, "title":"Draycott" }, { "title":"Regency", "doors":[ { "id":36, "title":"Canterbury" }, { "id":47, "title":"Exeter" }, <---- this comma is failing my json ], "product":{ "glass":[ { "id":7, "title":"Pad" }, { "id":6, "title":"Scroll" } ] } } My PHP: <?php echo '{'; $count = count($config) - 1; foreach($config as $key=>$conf) { $conf_price = $conf->getPrice() == '1'; if($conf_price) $conf_p = 'true'; else $conf_p = 'false'; echo "\"config\"".":",""; $config_array = array('logo'=>strtolower(str_replace(' ','-','uploads/global_config/scaled_'.$conf->getImage1())), 'deliveryCost'=>$conf->getDeliveryCost(), 'showPrice'=>$conf_p); if($key == $count){ echo json_encode($config_array).","."\n"; } else { echo json_encode($config_array).'},'."\n"; } } echo json_encode("range").": [\n"; $last_key = end(array_keys($categories)); foreach ($categories as $key => $cat) { if ($key == $last_key) { echo "{". "\"title\"".':'.'"'.$cat->getTitle().'"'.","."\"src\"".':'.'"'."-".strtolower(str_replace('.png','*.png',(str_replace(' ', '-', 'uploads/ranges/scaled_'.$cat->getImage1())))).'"' .","."\"info\"".':'.'"'.strip_tags($cat->getDescription()).'"'.","."\n"; } else { echo "{". "\"title\"".':'.'"'.$cat->getTitle().'"'.","."\"src\"".':'.'"'."-".strtolower(str_replace('.png','*.png',(str_replace(' ', '-', 'uploads/ranges/scaled_'.$cat->getImage1())))).'"' .","."\"info\"".':'.'"'.strip_tags($cat->getDescription()).'"'.","."\n"; } echo json_encode("doors").": [\n"; $count = count($cat->getAllDoorStyles()) - 1; foreach ($cat->getAllDoorStyles() as $key=>$door) { $array2 = array('id'=>$door->getId(), 'title'=>$door->getTitle(), 'src'=>strtolower(str_replace('.png','*.png',(str_replace(' ', '-', 'uploads/doors/scaled_'.$door->getImage1())))), 'price'=>$door->getPrice(), 'description'=>strip_tags($door->getDescription())); if($key == $count) { echo json_encode($array2).''."\n"."".","; } else { echo json_encode($array2).''."\n"."".""; } } } echo "\n"; echo "],"."\"Product:\"". '{ '; echo json_encode("glass").": [\n"; $count = count($glass) - 1; foreach($glass as $key => $glass_cat) { $glass_array = array('id'=>$glass_cat->getId(), 'title'=>$glass_cat->getTitle(), 'price'=>$glass_cat->getPrice(),'src'=>strtolower(str_replace('.png','*.png',(str_replace(' ', '-', 'uploads/glass_option/scaled_'.$glass_cat->getImage1()))))); if($key == $count) { echo json_encode($glass_array)."\n"; } else { echo json_encode($glass_array).','."\n"; } } echo ']'; echo '}'; echo '}'; I need to omit the comma that is causing me my problem All help welcomed Quote Link to comment Share on other sites More sharing options...
