Php 清理并添加具有未知字段数的Post Meta

我有一个像这样的领域

<input type="text" name="summary" value="" required />

<input type="text" name="cat_01" value="" />
<input type="number" name="dog_01" value="" />
<input type="number" name="rabbit_01" value="" />
<input type="text" name="mouse_01" value="" />

<input type="text" name="cat_02" value="" />
<input type="number" name="dog_02" value="" />
<input type="number" name="rabbit_02" value="" />
<input type="text" name="mouse_02" value="" />

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

但是当涉及到我需要存储在DB中的额外post_meta时，我不知道如何进行，因为我不知道表单中会有多少额外字段。这将有所不同

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

所以额外的表单字段可能是这样的

<input type="text" name="summary" value="" required />

<input type="text" name="cat_01" value="" />
<input type="number" name="dog_01" value="" />
<input type="number" name="rabbit_01" value="" />
<input type="text" name="mouse_01" value="" />

<input type="text" name="cat_02" value="" />
<input type="number" name="dog_02" value="" />
<input type="number" name="rabbit_02" value="" />
<input type="text" name="mouse_02" value="" />

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

…但有时可能会有第三组字段，或第四组字段等，而且实际上没有限制，我不知道会有多少组字段

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

例如，如果有第三组这些字段，它们将如下所示：

<input type="text" name="cat_03" value="" />
<input type="number" name="dog_03" value="" />
<input type="number" name="rabbit_03" value="" />
<input type="text" name="mouse_03" value="" />

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

所以你明白了

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

当我不知道我将要捕获什么时，我如何进行清理并添加_post_meta

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

干杯。

您可以使用

foreach

迭代任意数量的字段。

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

例如：

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

为什么不让自己轻松一点，并将所有这些数据保存在一个数组中，如下所示：

<!-- With type -->
<input type="text" name="animal[dog][]" value=""/>
<input type="text" name="animal[cat][]" value="" />
<!-- No Type -->
<input type="text" name="animal[]" value="" />

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

这与我已经创建的类似，字段是动态完成的，我们不知道需要节省多少

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

我希望这将为您提供一个如何制作的指南。

在下面的代码中，我使用了一个限制为4的数组，直到您使用了您的动物集。然后检查哪个是发布的，然后调整post变量

    $sanited_array = array();
    for($i = 1 ; $i < 4 ; $i++)
    {

    if(isset($_POST['cat_0'.$i]))
    {
        $sanited_array['cat'][] = sanitize_text_field($_POST['cat_0'.$i]);
    }
    if(isset($_POST['dog_0'.$i]))
    {
        $sanited_array['dog'][] = sanitize_text_field($_POST['dog_0'.$i]);
    }
    if(isset($_POST['rabbit_0'.$i]))
    {
        $sanited_array['rabbit'][] = sanitize_text_field($_POST['rabbit_0'.$i]);
    }
    if(isset($_POST['mouse_0'.$i]))
    {
        $sanited_array['mouse'][] = sanitize_text_field($_POST['mouse_0'.$i]);
    }
}
update_post_meta( $post_id, 'animal', $sanited_array );

$sanited_array=array（）；
对于（$i=1；$i<4；$i++）
{
如果（isset（$\u POST['cat\u 0'.$i]））
{
$sanited_数组['cat'][]=sanitize_文本_字段（$\u POST['cat_0'.$i]）；
}
如果（isset（$\u POST['dog\u 0'.$i]））
{
$sanited_数组['dog'][]=sanitize_文本_字段（$\u POST['dog_0'.$i]）；
}
如果（isset（$\u POST['rabbit\u 0'.$i]））
{
$sanited_数组['rabbit'][]=清理_文本_字段（$\u POST['rabbit_0'.$i]）；
}
如果（isset（$\u POST['mouse\u 0'.$i]））
{
$sanited_数组['mouse'][]=sanitize_文本_字段（$\u POST['mouse_0'.$i]）；
}
}
更新_post_meta（$post_id，$animal'，$sanited_数组）；

对于那些不熟悉PHP处理POST变量的人来说，这依赖于PHP内置的对提交值的折叠，将以“[]”结尾的名称折叠成一个数组。顺序应始终与DOM顺序相同
