Question

我在php中有这个数组：

    $field_data = array(
    'add_image' => array(
        array(
            'image_caption' => $caption,
            'upload' => $attachname,
        ),
    ),
  );

我需要在数组中添加一些东西，使它看起来像这样：

$field_data = array(
'add_image' => array(
    array(
        'image_caption' => $caption,
        'upload' => $attachname,
    ),
   array(
        'image_caption' => $caption,
        'upload' => $attachname,
    ),
),

）;

我尝试了数组推送，但我无法让它正常工作。任何帮助将不胜感激。

Answer 1

你真的不需要一个功能，就这样做：

$field_data['add_image'][] = $to_append_array;

Answer 2

尝试这样的事情：

$newEntry = array(
    'image_caption' => $caption,
    'upload' => $attachname,
);

$field_data['add_image'][] = $newEntry;

Answer 3

$field_data = array(
    'add_image' => array(
        1 = > array(  //you may not realize,but this array has key 1 and value array()
            'image_caption' => $caption,
            'upload' => $attachname
        ),
    ),
);

添加另一个add_image

$field_data['add_image'][] = array('image_caption' => $caption2, 'upload' => $attachname2);

添加image_title

$field_data['add_image'][1]['image_title'] = "Picture of House";

在完成这两项操作之后，您最终得到：

$field_data = array(
    'add_image' => array(
        1 = > array(
            'image_caption' => $caption,
            'upload' => $attachname,
            'image_title' => "Picture of House"
        ),
        2 = > array(
            'image_caption' => $caption2,
            'upload' => $attachname2
        ),
    ),
);
