重新加载页面并返回上一页后选中的复选框

Question

我只需要检查一下即可！不是全部。

<?php if (isset($_SESSION["design"])) { ?>
<input type="checkbox" onkeypress="isInputNumber(event)" name="design" value="<?php echo $design_id; ?>" checked>
<?php } else {?>
<input type="checkbox" onkeypress="isInputNumber(event)" name="design" value="<?php echo $design_id; ?>">
<?php } ?>

Answer 1

这是工作代码，请遵循它以使用isset方法。

<?php if (isset($_SESSION["design"]) && $_SESSION["design"] == $design_id) { ?>
<input type="checkbox" onkeypress="isInputNumber(event)" name="design" value="<?php echo $design_id; ?>" checked>
<?php } else {?>
<input type="checkbox" onkeypress="isInputNumber(event)" name="design" value="<?php echo $design_id; ?>">
<?php } ?>
