writing APIC to mp3 file with getid3 (id3v2) - php

Question

I am trying to write APIC picture to mp3 file with getid3. here is the code;
$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
);
but it doesnt work. image size is around 1.5 MB. should i resize it or sth ?
where am i wrong ?

Answer 1

Looking at the demo they have on their website: http://www.getid3.org/source/demo.write.phps
snippet of code:
$fd = fopen($_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];
}
Seems like the data key needs to be the image content, not just the path to the image file.
So in your case, it should be something like:
$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
);
Note: This is just after a quick glance at the demo code, I have not used this library or tested this code.

Answer 2

GetID3 needs the content of the file to be send for the data, not the file path. Then only it will be able to embed them into the file. Try
$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
);
tested and working :)

Answer 3

I found this in the source code:
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>
So picture data must be binary.
The solution is here: getid3 demo

Answer 4

This one is working for me for long time:
$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

$tagwriter->remove_other_tags = true;
// populate data array
$TagData = array(
'title' => array('My Song'),

);
$fd = fopen($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)
))
);
}
$tagwriter->tag_data = $TagData;
// write tags
if ($tagwriter->WriteTags()) {
echo 'Successfully wrote tags<br>';
if (!empty($tagwriter->warnings)) {
echo 'There were some warnings:<br>'.implode('<br><br>', $tagwriter->warnings);
}
} else {
echo 'Failed to write tags!<br>'.implode('<br><br>', $tagwriter->errors);
}
For anyone who just needd to update their ID3 tags including the Album Art , above code works just fine You need to have getID3 library to work .
