PHP 在具有多个表单输入的同一列中添加数据

Question

我有一个包含 v_name 和 l_value 列的表，我必须从

添加数据

    id       v_name    l_value
---------- ---------- ----------
1          SITE_URL    localhost/sitename

2          SITE_EMAIL  email@email.com

我的表格是

<form role="form" action="" method="post" >
<div class="form-group">
<label>Page Url</label>
<input type="hidden" placeholder="Enter Page Title" class="form-control"  name="v_name" id="SITE_URL" value="SITE_URL" required>
<input type="text" placeholder="Enter Page Title" class="form-control"  name="l_value" id="SITE_URL" value="" required>
</div>

<div class="form-group">
<label>Page Email</label>
<input type="hidden" placeholder="Enter Page Title" class="form-control" name="v_name" id="SITE_EMAIL" value="SITE_EMAIL" required>
<input type="text" placeholder="Enter Page Title" class="form-control"  name="l_value" id="SITE_EMAIL" value="" required>
</div>

<div class="form-group">
<button class="btn btn-primary" type="submit" name="submit_btn" value="submit">submit</button>
</div>
</form>

我有 2 个输入，但我希望将我的数据添加到单个表列中。

您应该在 name 属性中使用 [] 表示法:

<label>Page Url</label>
<input type="hidden" placeholder="Enter Page Title" class="form-control"  name="v_name[]" id="SITE_URL" value="SITE_URL" required>
<input type="text" placeholder="Enter Page Title" class="form-control"  name="l_value[]" id="SITE_URL" value="" required>
</div>

<div class="form-group">
<label>Page Email</label>
<input type="hidden" placeholder="Enter Page Title" class="form-control" name="v_name[]" id="SITE_EMAIL" value="SITE_EMAIL" required>
<input type="text" placeholder="Enter Page Title" class="form-control"  name="l_value[]" id="SITE_EMAIL" value="" required>
</div>

在服务器端，您可以通过 $_POST 数组访问值(如果请求方法是 POST):

foreach ($_POST['v_name'] as $key => $name) {
    echo $name . ' and ' . $_POST['l_value'][$key];
}
