如何解决自PHP 7.2起不推荐使用函数read_exif_data
在WP中针对PHP 7.3进行兼容测试时,我得到此报告:
从PHP 7.2开始不推荐使用read_exif_data()函数;请改用exif_read_data()
我应该按字面意思更改它,还是需要以更多方式重写该函数?
这是我的代码:
function ww_upload_photo() {
// These files need to be included as dependencies when on the front end.
require_once ABSPATH . 'wp-admin/includes/file.php';
// Let WordPress handle the upload.
// Remember,'my_image_upload' is the name of our file input in our form above.
foreach ($_FILES['files'] as $key => $val) {
$file[$key] = $val[0];
}
$uploaded_file = wp_handle_upload($file,array(
'test_form' => false,'test_type' => false,));
if ($uploaded_file && !isset($uploaded_file['error'])) {
// $filename should be the path to a file in the upload directory.
$filename = $uploaded_file['file'];
// The ID of the post this attachment is for.
$parent_post_id = null;
// Check the type of file. We'll use this as the 'post_mime_type'.
$filetype = wp_check_filetype(basename($filename),null);
// Get the path to the upload directory.
$wp_upload_dir = wp_upload_dir();
// Prepare an array of post data for the attachment.
$attachment = array(
'guid' => $wp_upload_dir['url'] . '/' . basename($filename),'post_mime_type' => 'image/jpeg','post_title' => preg_replace('/\.[^.]+$/','',basename($filename)),'post_content' => '','post_status' => 'inherit',);
// Insert the attachment.
$attachment_id = wp_insert_attachment($attachment,$filename,$parent_post_id);
$attachment_url = wp_get_attachment_url($attachment_id);
$attachment_uri = get_attached_file($attachment_id);
// $selection = json_decode(stripslashes($_POST['selection']),true);
$image = wp_get_image_editor($attachment_uri);
if (!is_wp_error($image)) {
// $exif = exif($uploaded_file);
$exif = read_exif_data($uploaded_file['file']);
//We're only interested in the orientation
$orientation = isset($exif['Orientation'])?$exif['Orientation']:0;
switch($orientation){
case 1: // nothing
break;
case 2: // horizontal flip
$image->flip(true,false);
break;
case 3: // 180 rotate left
$image->rotate(180);
break;
case 4: // vertical flip
$image->flip(false,true);
break;
case 5: // vertical flip + 90 rotate right
$image->flip(false,true);
$image->rotate(-90);
break;
case 6: // 90 rotate right
$image->rotate(-90);
break;
case 7: // horizontal flip + 90 rotate right
$image->flip(true,false);
$image->rotate(-90);
break;
case 8: // 90 rotate left
$image->rotate(90);
break;
}
#$image_old_size = $image->get_size();
// $image->crop($selection['x'],$selection['y'],$selection['w'],$selection['h']);
#$image->resize( 300,300,true );
$saved = $image->save($attachment_uri);
#$image->save($uploaded_file['url']);
}
// Make sure that this file is included,as wp_generate_attachment_metadata() depends on it.
require_once ABSPATH . 'wp-admin/includes/image.php';
// Generate the metadata for the attachment,and update the database record.
$attach_data = wp_generate_attachment_metadata($attachment_id,$filename);
wp_update_attachment_metadata($attachment_id,$attach_data);
$success = array(
'attachment_id' => $attachment_id,'attachment_url' => $attachment_url,'attachment_meta' => $attach_data,'message' => 'File is valid,and was successfully uploaded.\n',);
update_field('order_media',true,$attachment_id);
wp_send_json_success($success);
} else {
/**
* Error generated by _wp_handle_upload()
* @see _wp_handle_upload() in wp-admin/includes/file.php
*/
wp_send_json_success($uploaded_file['error']);
}
}
解决方法
根据官方documentation read_exif_data()
仅为exif_read_data()
函数的别名,并且该别名在PHP 7.2中已弃用。因此,您要做的就是将您使用的功能更改为exif_read_data()
。它们是100%兼容的。
