Question

我想知道如何检测和取消选中复选框并使其执行和操作。基本上，如果未选中该复选框，则应加载另一页。这似乎没有用，有什么帮助吗？

<?php
if(!isset($_POST['checkbox1'])) 
{
    $swag=fopen("empty.php","r");
}
?>

Answer 1

当在php端接收POST参数时，如果相对于复选框的参数进来，那是因为选中了复选框。如果参数没有进入POST参数，则取消选中。

您可以这样做：

if(isset($_POST['checkbox_parameter']){
    echo "Checkbox is selected!";
}
else {
    echo "Checkbox not selected.";
}

未选中的复选框，用于在php中执行操作
