我知道这个问题已经被问了好几次了，我已经看到了答案，但它已经对我有很大帮助，但我需要解决另一个问题。所以问题是：我需要用 php 构建 json 文件。这是我需要的 json 文件的外观：
{
"fashion":[
{
"alt":"Alisa",
"src":"img/fashion/Alisa/kubik.jpg",
"class":"albumItem",
"id":"FashionAlbum001",
"itemNum":0,
"album":[
{
"alt":"albumImg1",
"src":"img/fashion/Alisa/alisa1.jpg"
},
{
"alt":"albumImg1",
"src":"img/fashion/Alisa/alisa5.jpg"
},
{
"alt":"albumImg1",
"src":"img/fashion/Alisa/alisa7.jpg"
}
]
},
{
"alt":"2-Addis",
"src":"img/fashion/2-Addis/kubik.jpg",
"class":"albumItem",
"id":"FashionAlbum002",
"itemNum":1,
"album":[
{
"alt":"albumImg1",
"src":"img/fashion/2-Addis/addis1.jpg"
},
{
"alt":"albumImg4",
"src":"img/fashion/2-Addis/addis4.jpg"
}] } ] }
等等...我找不到如何在每个相册中制作图像列表这是一个 php 函数 a 有
function buildJson(){
$json = json_encode(array(
"Fashion" => array(
"alt" => "Alisa",
"src" => "img/fashion/Alisa/kubik.jpg",
"id" => "FashionAlbum001",
"itemNum"=>"1",
"album"=>array(
"src"=>"img/fashion/Alisa/alisa1.jpg",
),
array(
"src"=>"img/fashion/Alisa/alisa5.jpg",
),
array(
"src"=>"img/fashion/Alisa/alisa7.jpg",
),
)
));
echo $json;
}但我得到这样的 json：
{
"Fashion": {
"0": {
"src": "img/fashion/Alisa/alisa2.jpg"
},
"1": {
"src": "img/fashion/Alisa/alisa3.jpg"
},
"alt": "Alisa",
"src": "img/fashion/Alisa/kubik.jpg",
"id": "FashionAlbum001",
"itemNum": "0",
"album": {
"src": "img/fashion/Alisa/alisa1.jpg"
}
}
}
怎么可能修复它？谢谢！
请多注意你正在编写的代码:)尝试解码 json 文件的正确版本，并将其与您编写的文件进行比较。您应该会看到一些差异。
您的问题是album键之后的内容。您正在为数组分配只有一个值，而不是为其分配数组数组。
这是要走的路：
"album" => array(
array("src" => "img/fashion/Alisa/alisa1.jpg"),
array("src" => "img/fashion/Alisa/alisa5.jpg"),
array("src" => "img/fashion/Alisa/alisa7.jpg"),
),
嵌套专辑数组时遇到麻烦
固定代码
function buildJson(){
$json = json_encode(
array(
"Fashion" => array(
"alt" => "Alisa",
"src" => "img/fashion/Alisa/kubik.jpg",
"id" => "FashionAlbum001",
"itemNum"=>"1",
// nesting error here
"album"=> array(
array("src"=>"img/fashion/Alisa/alisa1.jpg"),
array("src"=>"img/fashion/Alisa/alisa5.jpg"),
array("src"=>"img/fashion/Alisa/alisa7.jpg")
)
)
)
);
echo $json;
}
