Question

我想要编辑表单，用户已选择值已表示我想以编辑形式显示已选中的复选框值，所以我正在尝试这样

<?php 
include("dbconfig.php");
$sql = "SELECT * FROM residential_propertytype WHERE status !='1'";
$result = mysql_query($sql);
while($pr_type = mysql_fetch_array($result))
{ 
$propty[] = $pr_type;

}
echo "<pre>";
var_dump($propty);
echo "</pre>";
foreach($propty as $res)
        {
        $checked = in_array($res['id'], 5) ? 'checked' : '';
        ?>

        <input type="checkbox" value="<?php echo $res['id']?>" <?php echo $checked; ?>><?php echo $res['propertyName']?>
        <?php
        }
?>

见下文 var_dump（$ propty）我得到这样的答案

array(10) {

在进行选中复选框值时，我收到错误警告：in_array（）期望参数2为数组，给定整数如何解决此问题

Answer 1

您需要定义，可能是您对5 ..

的意思

应该是这样的：$ array_list = array（1,2,3,4,5）;

$checked = in_array($res['id'], $array_list) ? 'checked' : '';

在您的示例中，您传递的是5而不是array

Answer 2

您知道要匹配的值和数组键，为什么要使用in_array()？

 $checked = ($res['id'] == 5) ? 'checked' : '';

Answer 3

在HTML表单代码中，您要创建数组的复选框都需要与末尾的括号相同。这样选中的复选框将在$ _POST数组

中形成一个数组

<form method=post action=yourstuff.php>
Pick your favorite pizza toppings -
<input type=checkbox name=topping[] value="pepperoni"> Pepperoni <br />
<input type=checkbox name=topping[] value="ex. chz"> Extra cheese <br />
<input type=checkbox name=topping[] value="black olives"> Black olives <br />
<input type=submit>
</form>

如何在数组中选中复选框值
