php - $_POST 复选框数组仅返回单个值

Question

$_POST['clients'] 最后的 foreach 循环仅返回一个值。怎么了？

 <?php $clients_to_display = Client::find_all(); ?>
            <p><?php foreach ($clients_to_display as $key) {
                echo $key->name; ?>:<input type='checkbox' name='clients[]' value=<?php $key->name; ?></><br/>
            <?php } ?></p>

        if(isset($_POST['submit'])){

        $job->name = $_POST["job_name"];
        $job->description = $_POST["job_description"];
        $job->type = $_POST["job_type"];
        $job->age = $_POST["job_age"];

    foreach ($_POST['clients'] as $key) {
        echo $key;
    }
}

Answer 1

此代码不执行任何操作:

<?php $key->name; ?>

我想你想要:

<?php echo($key->name); ?>

此外，它必须用引号引起来:

value="<?php echo($key->name); ?>"

标记也无效。因此，整行应该是:

echo($key->name); ?>:<input type="checkbox" name="clients[]" value="<?php echo($key->name); ?>" /><br/>
