主要就是利用upload_mimes过滤钩子,进行添加、修改、删除,代码放到主题functions.php或者放到插件里面.
例子1:
function my_custom_mime_types( $mimes ) {
// New allowed mime types.
$mimes['svg'] = 'image/svg+xml';
$mimes['svgz'] = 'image/svg+xml';
$mimes['doc'] = 'application/msword';
// Optional. Remove a mime type.
unset( $mimes['exe'] );
return $mimes;
}
add_filter( 'upload_mimes', 'my_custom_mime_types' );
例子2:
<?php
function svgz_mime_types( $mimes ) {
// SVGZ allowed mime types.
$mimes['svgz'] = 'application/x-gzip';
return $mimes;
}
add_filter( 'upload_mimes', 'svgz_mime_types' );
?>
例子3:
<?php
/**
* Allow JSON file uploads to WordPress media library.
*
* Filters the uploads mime types to allow JSON files.
*
* @param array $types Currently allowed types.
*
* @return array Filtered types.
*/
add_filter(
'upload_mimes',
function( $types ) {
return array_merge( $types, array( 'json' => 'text/plain' ) );
}
);
例子4:
function extend_mime_types( $types ) {
$types['csv'] = 'text/csv';
return $types;
}
add_filter( 'upload_mimes', 'extend_mime_types' );
例子5:
function wpdocs_allow_mime_types( $mimes ) {
$mimes['ttf'] = 'font/ttf';
$mimes['woff'] = 'font/woff';
$mimes['woff2'] = 'font/woff2';
return $mimes;
}
add_filter( 'upload_mimes', 'wpdocs_allow_mime_types' );
例子6:
// To upload photos in format WebP
function wpdocs_custom_mime_types( $mimes ) {
// New allowed mime types.
$mimes['webp'] = 'image/webp';
return $mimes;
}
add_filter( 'upload_mimes', 'wpdocs_custom_mime_types' );
