我在此代码上遇到问题...当我将商品添加到购物车时，它会将商品保留在购物车中，但却出现错误

Notice: Undefined index: bb in C:\xampp\htdocs\Webcart_ch\Webcart\mycart.php on line 85

指数＆＃39; bb＆＃39;在复选框上，如果勾选了复选框，则输出内容。我真的到了那里，但我不知道该怎么办！请帮忙..

Answer 1

我注意到这里有一个拼写错误的'book19'： if（$ aaa =='book9'）{$ _SESSION ['b'] = implode（“”，$ _ SESSION ['bookrec'] [' book19 ']）;}

如果这样可以解决问题，请告诉我：将'book19'更改为'book9'

if($aaa=='book9') {$_SESSION['b']=implode("<td>",$_SESSION['bookrec']['book9']);}
