我创建了一个带有复选框的简单表单,根据复选框是否设置,回显为真或假,但是每次勾选复选框控件后单击提交,它似乎都会重置。
如何修改我的代码以存储任何表单控件的值,如果我勾选方框,我点击提交后仍然会勾选?
<?php
// Setup Variables
$Result = '';
if (isset($_POST["submit"])) {
//Use Captials?
if(isset($_POST['formCheckbox']) && $_POST['formCheckbox'] == 'Yes') {
$Result = "true";
} else {
$Result = "false";
}
}
?>

添加已检查的属性&amp; 更改复选框的显示方式:
<?php
// Setup Variables
$Result = '';
if (isset($_POST["submit"])) {
//Use Captials?
if(isset($_POST['formCheckbox']) && $_POST['formCheckbox'] == 'Yes') {
$Result = "true";
} else {
$Result = "false";
}
}
?>
