将APIC写入带有getid3的mp3文件（id3v2）

问题描述：

我正在尝试将APIC图片写入带有getid3的mp3文件。这里是代码;将APIC写入带有getid3的mp3文件（id3v2）

$cover = "/home/user/public_html/artwork/cover.jpg"; 
$TagData['attached_picture'][]=array(
'picturetypeid'=>2, // Cover. More: module.tag.id3v2.php -> function APICPictureTypeLookup 
'description'=>'cover', // text field 
'mime'=>'image/jpeg', // Mime type image 
'data'=>$cover // Image data 
);

但它不工作。图像大小约为1.5 MB。我应该调整它还是......？

我在哪里错了？

感谢

你在使用什么库，以及如何将数据保存到MP3文件？ – 2011-01-30 17:26:04

我使用getid3库http://www.getid3.org/ – 2011-01-30 17:30:02

看着他们在其网站上的演示：http://www.getid3.org/source/demo.write.phps

的代码片段：

$fd = fopen($_FILES['userfile']['tmp_name'], 'rb') 
$APICdata = fread($fd, filesize($_FILES['userfile']['tmp_name'])); 
fclose ($fd); 

$imagetypes = array(1=>'gif', 2=>'jpeg', 3=>'png'); 
if (isset($imagetypes[$APIC_imageTypeID])) { 
    $TagData['attached_picture'][0]['data']   = $APICdata; 
    $TagData['attached_picture'][0]['picturetypeid'] = $_POST['APICpictureType']; 
    $TagData['attached_picture'][0]['description'] = $_FILES['userfile']['name']; 
    $TagData['attached_picture'][0]['mime']   = 'image/'.$imagetypes[$APIC_imageTypeID]; 
}

好像数据的关键必须是图像内容，而不仅仅是图像文件的路径。所以你的情况，应该是这样的：

$cover = "/home/user/public_html/artwork/cover.jpg"; 
$fd = fopen($cover, 'rb') 
$APICdata = fread($fd, filesize($coverFile)); 
fclose ($fd); 

$TagData['attached_picture'][]=array(
'picturetypeid'=>2, // Cover. More: module.tag.id3v2.php -> function APICPictureTypeLookup 
'description'=>'cover', // text field 
'mime'=>'image/jpeg', // Mime type image 
'data'=>$APICdata // Image data 
);

注意：这仅仅是在之后的演示代码看一眼，我没有用过这个库或测试此代码。

GetID3需要为数据发送文件的内容，而不是文件路径。那么只有它可以将它们嵌入到文件中。尝试

$cover = "/home/user/public_html/artwork/cover.jpg"; 
$TagData['attached_picture'][]=array(
    'picturetypeid'=>2, // Cover. More: module.tag.id3v2.php -> function APICPictureTypeLookup 
    'description'=>'cover', // text field 
    'mime'=>'image/jpeg', // Mime type image 
    'data'=> file_get_contents($cover) // Image data; not the file name 
);

测试工作:)

我发现这个源代码：

case 'APIC': 
    // 4.14 APIC Attached picture 
    // Text encoding  $xx 
    // MIME type   <text string> $00 
    // Picture type  $xx 
    // Description  <text string according to encoding> $00 (00) 
    // Picture data  <binary data>

所以图像数据必须是二进制。

这一个是为我工作了很长一段时间：

$TagData = array(); //your other tags 
    $fd = fopen($albumPath, 'rb'); 
    $APICdata = fread($fd, filesize($albumPath)); 
    fclose($fd); 

    if($APICdata) { 
     $TagData += array(
      'attached_picture' => array(0 => array(
       'data'   => $APICdata, 
       'picturetypeid' => '0x03', 
       'description' => 'cover', 
       'mime'   => image_type_to_mime_type($albumExifType) 
      )) 
     ); 
    } 
    //and write the tags to file

对于任何人谁只是needd更新他们的ID3标签，包括专辑封面，上面代码工作得很好你需要让get3库去工作。这个答案是基于JacopKane的答案，所以他的功劳
