这是我需要的输出：

{
    "album": "Text_Input",
    "artwork": "DefaultURL/http://www.ggcc.tv/ArmyoftheLord/Army%20of%20the%20Lord.png/OR Overwrite with Uploaded Image",
    "church": "City Name And State Wich can be selected from Dropdown Menu",
    "cityartwork": "Default URL Will Be Set/ This input is hidden",
    "des": "Text_Input_For_Description",
    "release_date": "February 24th 2013 ",
    "tracks": [
        {
            "name": "Text_Input",
            "url": "File Upload of .MP3 which should be saved on server and its new url should be inputed here by the script"
        },
        {
            "name": "Text_Input",
            "url": "File Upload of .MP3 which should be saved on server and its new url should be inputed here by the script"
        },
        {
            "name": "Text_Input",
            "url": "File Upload of .MP3 which should be saved on server and its new url should be inputed here by the script"
        },
        {
            "name": "Text_Input",
            "url": "File Upload of .MP3 which should be saved on server and its new url should be inputed here by the script"
        },
        {
            "name": "Text_Input",
            "url": "File Upload of .MP3 which should be saved on server and its new url should be inputed here by the script"
        },
        {
            "name": "Text_Input",
            "url": "File Upload of .MP3 which should be saved on server and its new url should be inputed here by the script"
        }
    ]
}

我需要一个表单来收集所有这些信息，将其保存到数据库并将收集到的条目输出到服务器上的单个 JSON 文件中，以便我可以在我正在处理的应用程序中使用该 .json 文件。

您可以使用以数组索引 ex: 命名的表单元素创建一个表单， <input type="text" name="record[album]"/>依此类推。

将表单发布到服务器后，您json_encode($_POST['record'])当然可以在验证后使用 来获取所需的 json 输出。

尝试这个：

<?php
$minimum_tracks=1;
$maximum_tracks=10;

$tracks=isset($_GET['tracks'])?$_GET['tracks']:0;

if (is_numeric($tracks) && $tracks>=$minimum_tracks && $tracks<=$maximum_tracks) {
    if ($_SERVER['REQUEST_METHOD'] === 'POST') {
        $_POST['cityartwork']="Default Set from PHP";
        $_POST['tracks']=array();
        $_POST['artwork']='http://www.ggcc.tv/ArmyoftheLord/Army%20of%20the%20Lord.png';
        if ($_FILES['artwork']['size']!=0) {
            move_uploaded_file($_FILES['artwork']['tmp_name'],"artworks/".$_FILES['artwork']['name']);
            $_POST['artwork']=$_SERVER['HTTP_HOST']."/artworks/".$_FILES['artwork']['name'];
        } 
        for ($i=0;$i<$tracks;$i++) {
            $filename="tracks/".$_FILES['tracks']['name'][$i];
            $_POST['tracks'][$i]=array(
                "name"=>$_POST['track_names'][$i],
                "url"=>$_SERVER['HTTP_HOST']."/".$filename
            );
            move_uploaded_file($_FILES['tracks']['tmp_name'][$i],$filename);
        }
        unset($_POST['track_names']); 
        echo json_encode($_POST);
        exit;
    } else {

添加到 Shoan 的答案：您还需要创建一个带有 javascript 处理程序的按钮来创建更多输入，以便用户可以根据需要添加更多轨道。附加输入需要如下所示：

<input type="text" name="record[tracks][n][name]"/>

n下一首曲目的号码在哪里。
