我试图将POST值存储到选定的复选框中,我在提交表单后存储数据时遇到了一些问题。这就是我所拥有的:
<fieldset>
<legend>Categories:</legend>
<?php $sql3 = 'SELECT id, name FROM category';
foreach ($dbConnection->query($sql3) as $category) { ?>
<div>
<label for="category<?php echo($category['id']);?>">
<input type="checkbox" name="categories[]" id="category<?php echo($category['id']); ?>" value="<?php echo($category['id']); ?>"
<?php if(isset($_POST['category']) && $_POST['category'] == $category['id']) { echo 'checked'; } ?>>
<?php echo($category['name']); ?></label>
</div>
<?php } ?>
</fieldset>
有人可以借助它吗?
答案 0 :(得分:1)
将你的if语句更改为:
<?php if(isset($_POST['categories']) && in_array($category['id'],$_POST['categories'])) { echo 'checked'; } ?>>
<?php echo($category['name']); ?></label>
