详情介绍:

Turn your Media Library requirements into clear, consistent upload rules. Kodlo Media Manager adds a focused rules builder to Settings -> Media. Define which formats WordPress may accept, where each format is allowed, how large an upload may be, which image dimensions are acceptable, and how filenames should be formatted. The plugin validates uploads on the server and provides early feedback in the standard WordPress media uploader. It uses native WordPress, PHP, and browser APIs and includes no third-party libraries or external services. SVG and WebP Ready After Activation On a fresh installation, Kodlo Media Manager automatically configures SVG and WebP uploads for the standard WordPress Media Library. No code snippet, manual MIME filter, or separate SVG upload plugin is required. SVG files are sanitized locally on the server before WordPress stores them. The plugin removes unsupported or potentially active content, rejects external references and malformed SVG documents, and accepts only the canonical .svg extension and image/svg+xml MIME type. WebP files can be uploaded and used through the normal WordPress media workflow while the plugin enforces the configured MIME type, file size, image dimensions, filename, and duplicate rules. Why Use Kodlo Media Manager? Upload Rules Each rule combines a file extension and MIME type with one of three policies: WordPress uses several upload flows beyond the Media Library. Importers, plugin and theme installers, custom frontend forms, and third-party tools may upload files through different WordPress endpoints. The separate policies let you allow a format only where it is needed instead of enabling it for every upload flow on the site. Allowed (Media Library Only) is the recommended choice for content files such as SVG, WebP, AVIF, PDF, and regular images. It includes uploads made through the standard Media Library modal used by WordPress editors and normal Elementor image controls. Selecting or reusing a file that is already in the Media Library is not restricted by these upload policies. Use Allowed (Globally) only when the format must also work outside the standard Media Library, such as through an importer, a custom upload form, or a third-party tool with its own upload endpoint. Some specialized Elementor features or add-ons may use such custom endpoints even though normal Elementor image selection uses the WordPress Media Library. An administrator can also set a per-format maximum file size and, for raster images, maximum width and height. Dangerous executable and active-content formats remain unavailable even if they are submitted through malformed settings data. Filename and Duplicate Controls The filename validator accepts a bounded regular-expression subset shared by PHP and JavaScript. Unsupported, malformed, or excessive patterns fall back to the plugin's safe default. Optional auto-sanitization can reshape filenames for compatible positive character-class patterns before validation; safe validation-only patterns remain available without automatic rewriting. Duplicate Guard compares exact normalized basenames rather than image contents. Every distinct filename is checked directly against Media Library attachment metadata. Short-lived hashed upload locks prevent two plugin-managed requests from claiming the same available filename at the same time, without building a filename index or custom database table. SVG Handling The internal SVG sanitizer accepts a limited set of SVG elements and attributes, removes unsupported content, rejects document types and entities, and permits only safe internal fragment references. It also applies a fixed payload ceiling before DOM parsing. SVG content must use the canonical .svg extension and image/svg+xml MIME pair. SVG sanitization is a focused upload safeguard. It does not replace appropriate WordPress capabilities, server hardening, backups, or review of untrusted content. Media Uploader Experience The browser-side guard mirrors format, filename, size, dimension, and duplicate checks to provide feedback before an upload begins. Asynchronous dimension probes and duplicate lookups share one validation barrier, use bounded batches, concurrency, and timeouts, and finish before a paused queue resumes. Invalid or unavailable duplicate responses stop affected files and explain the failure. Server-side validation remains authoritative for native uploads and sideload-based REST uploads. Warning dialogs use native button semantics, labelled dialog markup, Escape handling, managed keyboard focus, and focus restoration. Settings controls include accessible names and predictable focus movement when rules are added or removed. Default Configuration The initial rules allow ZIP globally so WordPress can upload plugin and theme packages. SVG, WebP, AVIF, MP4, WebM, PDF, DOCX, and WOFF2 start in Media Library contexts with format-specific limits, while JPG, JPEG, and PNG start blocked. These defaults are a starting point, not a universal recommendation; review them for your site's editorial workflow and hosting limits. By default, verified uploads initiated by an administrator from WordPress General Settings bypass format, filename, duplicate, size, and dimension policies so core settings such as the site icon are not unexpectedly blocked. SVG files are still sanitized. Enable General Settings Page Uploads to apply the configured policies there as well. Deactivation and Uninstall Deactivating Kodlo Media Manager turns off its upload rules and interface but preserves all saved settings, so the same configuration is available if the plugin is activated again. Deleting the plugin through the WordPress Plugins screen runs its uninstall cleanup. The plugin removes all of its saved settings and any remaining temporary upload locks, including across a WordPress Multisite network, leaving no plugin-specific options or custom database tables behind. Try It Before Installing Use Live Preview on WordPress.org to explore the upload rules directly in Settings -> Media before installing the plugin.

安装:

  1. Upload the kodlo-media-manager directory to /wp-content/plugins/, or install the plugin through the WordPress Plugins screen.
  2. Activate Kodlo Media Manager.
  3. Go to Settings -> Media.
  4. Review every default rule and adjust the policies, limits, filename pattern, and Duplicate Guard setting for your site.
  5. Test the intended administrator and contributor upload workflows before applying the rules to a production editorial team.

常见问题:

Does the plugin optimize or convert uploaded files?

No. It validates configured formats, sizes, dimensions, filenames, duplicate names, and SVG content. It does not compress images, convert JPG or PNG files to WebP or AVIF, or remove unused media.

Do I need another plugin or a code snippet to upload SVG and WebP files?

No. On a fresh installation, SVG and WebP are already allowed in verified WordPress Media Library upload flows. SVG sanitization requires the PHP DOM/XML extension. Existing installations retain their saved rules after an update.

Why are JPG, JPEG, and PNG blocked by default?

The initial profile encourages a WebP or AVIF workflow. It is only a starting point. Change the applicable rule to Allowed (Media Library Only) or Allowed (Globally) if your project uses JPG, JPEG, or PNG.

Why is ZIP allowed globally by default?

WordPress handles administrator-uploaded plugin and theme ZIP packages outside the Media Library. Allowing ZIP globally keeps those native installation workflows available, while WordPress's own capability and package validation still apply. Change the rule only if your site has a different package-upload policy and you have tested the affected administration screens.

What does a maximum size of zero mean?

Zero or a blank value disables the plugin's per-format size limit for that rule. WordPress, PHP, the web server, and the hosting provider may still impose their own limits.

What is the difference between the three upload policies?

Allowed (Media Library Only) requires a verified Media Library context. Allowed (Globally) also permits the configured format in other WordPress upload contexts. Blocked (Globally) rejects the format throughout WordPress upload handling.

How does Duplicate Guard work?

It blocks exact normalized filename matches, not visually similar images or identical file contents with different names. Each distinct name is queried directly against Media Library attachment metadata. A short-lived hashed lock closes the race between lookup and storage for plugin-managed uploads. If WordPress cannot verify a name, the upload is stopped conservatively and can be retried.

Does Duplicate Guard create a filename index or change attachment data?

No. Each filename is checked directly against existing _wp_attached_file metadata. The plugin does not rewrite attachment content, add attachment metadata, or maintain a custom filename table. Concurrent plugin-managed uploads use short-lived hashed option locks that do not contain the original filename.

How does the SVG sanitizer work?

Canonical .svg uploads are parsed locally with PHP's DOM extension. The sanitizer uses element and attribute allowlists, accepts only safe internal fragment references, and rejects document types, entities, external URLs, foreign namespaces, event handlers, and other unsupported active content. Files above the fixed parser ceiling are rejected before DOM parsing.

Can I use a custom filename pattern?

Yes. Patterns must be anchored and remain within the bounded subset that the plugin can evaluate consistently in PHP and JavaScript. Groups, alternation, backreferences, engine-specific escapes, excessive lengths, invalid quantifiers, and malformed expressions are rejected in favor of the default pattern. A regular expression, often shortened to "regex," is a compact pattern that describes which characters and structure a filename may contain. The MDN Regular Expressions Guide provides an accessible introduction to patterns, character classes, anchors, and quantifiers. The default pattern is ^[a-zA-Z0-9_\.-]+\.[a-zA-Z0-9]+$. The ^ and $ anchors require the complete filename to match. The character classes allow Latin letters, numbers, underscores, hyphens, and dots, while the escaped \. requires a dot before the file extension. You can experiment with patterns using the free regex101 builder and tester. Treat it as a learning and testing aid: regex101 supports syntax that Kodlo Media Manager intentionally rejects. A pattern must still pass the plugin's validation in Settings -> Media, and you should test representative valid and invalid filenames before applying it to a production editorial workflow.

How does filename auto-sanitization work?

When enabled for a compatible positive character-class pattern, the plugin mirrors the active WordPress locale's accent conversions in the media uploader, transliterates supported Cyrillic characters, chooses a separator that fits the pattern, normalizes letter case when practical, and removes unsupported characters. The server applies WordPress filename sanitization once and validates WordPress's final unique filename again before storage. Patterns with required literals, negated classes, or other constructs that cannot be generated deterministically remain validation-only and automatically disable rewriting.

How are image dimensions and WordPress big-image scaling handled?

When a rule defines width or height limits, the plugin verifies the uploaded raster image dimensions. For active rules, it also adjusts WordPress's big-image threshold to reflect the configured bounds while preserving a threshold that another component has explicitly disabled.

Does the plugin affect frontend performance?

The plugin does not enqueue assets on public frontend pages. Upload validation runs only in relevant administrator or upload contexts. Duplicate Guard uses direct per-filename Media Library queries and deliberately rechecks an available name after locking and before movement, so its upload-time cost depends on upload volume, Media Library size, and database performance.
