详情介绍:
Ask your visitors for their details before a PDF downloads. You build the form, each request arrives in your inbox, and the file is handed out through a signed link that expires, so the link someone forwards stops working instead of living forever.
Add your PDF catalogs, coupons or price lists, and drop a download button anywhere with a shortcode or a data attribute on any existing button.
Download form
- A form opens when a visitor clicks a download button, and the PDF opens once they send it
- Build it yourself with the basic fields: name, email, text, paragraph, number, dropdown, single choice, checkboxes, and a consent checkbox that links to your privacy page, with the link text you choose
- Reorder fields by dragging or with the keyboard, mark them required, add help text, and see the form open on a page of your own site as you edit, at desktop, tablet or phone size
- Write your own title, introduction, button label and thank-you message, and pick the button colors
- Email notifications like WPForms: choose who gets each request (one address or several), the sender, the subject and the message, with tags for every answer, in HTML or plain text; replying writes straight to the visitor
- Spam protection: a hidden trap field, a limit per visitor and optional Cloudflare Turnstile
- Accessible dialog: keyboard focus stays inside, Esc closes it, and errors are announced next to each field
- Works with page caching, and uses your theme's font so it matches your site
- Add as many PDF catalogs as you like, one at a time
- Every PDF is stored in a private folder with an unguessable name and served only through a signed link that stops working after 30 minutes
- Shortcode
[catr_download_button id="123"], plus adata-catr-catalog="123"attribute for any button or link - A clean admin that works on phones, with notices from other plugins kept above it, and a download button that inherits your theme's style
- Leads: every request saved in a list you can search and export to CSV
- Notifications: up to ten per form, each sent only when an answer says so, a different inbox for each catalog, and your logo and color on them
- Metrics: downloads, requests and conversion rate for each catalog, and the campaign every lead came from
- More fields: phone with country code and validation (ten digits for the US, Canada and Mexico), website, date, country and state, hidden campaign fields, fields that show up depending on an answer, and two-column layouts
- Content: headings, text blocks, images and dividers anywhere in the form, and a form without a visible title
- Ways to ask: an optional form, the file sent to the visitor's email, returning visitors remembered, and a different form or mode for each catalog
- Your brand: every color, rounded corners for the window, the fields and the button, Google Fonts served from your own site or your own font files, weight, italic, underline and capitals for each part of the form, field styles, your logo, a blurred backdrop, and a form that slides in from the side or rises from the bottom on phones
- Big catalogs: PDFs larger than your hosting allows, bulk import, catalog export, and your own link duration
安装:
- Install the plugin from Plugins → Add New, or upload the
templates-rocket-catalog-managerfolder to/wp-content/plugins/. - Activate it.
- Go to Catalogs to add your first PDF catalog.
- Place a button with the shortcode
[catr_download_button id="X"](replace X with the catalog ID), or adddata-catr-catalog="X"to any existing button. - Adjust the form under Catalogs → Download form.

常见问题:
Where do the visitor's answers go?
To your inbox. Under Catalogs → Download form → Email you choose who gets each request (one address or several), the sender, the subject and the message, as in WPForms; replying to it writes to the visitor. This plugin does not store the answers in your database. Catalog Rocket Pro keeps them in a list you can search and export.
Can I skip the form for some catalogs?
In this plugin the form is on or off for the whole site. Catalog Rocket Pro lets you choose for each catalog: a form, an optional form, the file sent by email, or no form at all.
Does the form work with page caching?
Yes. The download request does not depend on a token printed in the page, so cached pages keep working. Bots are stopped by a hidden trap field, a limit of 10 requests every 10 minutes per visitor and, if you add your keys, Cloudflare Turnstile.
I updated from an earlier version. Did anything change for my visitors?
Only the link duration. On sites that already had catalogs, the form starts switched off and downloads work as before, through links that now always last 30 minutes. Turn the form on under Catalogs → Download form when you are ready.
Is there a limit on the number of PDFs?
No. Add as many catalogs as you like.
Are the PDF files really protected?
Yes, both the link and the file. Every download is handed out as an HMAC-signed link that stops working after 30 minutes, so a link that gets forwarded or posted somewhere is dead by the time anyone else opens it. Every PDF you add is stored in a private folder with an unguessable name, so the only way in is through a valid link. A PDF you add with Choose a PDF, or drop on the page, never has a public URL. A PDF you pick from the Media Library is copied into the private folder, and the original stays in the Media Library with its normal URL; the catalog row marks it as a Public copy, with a button to remove it.
Does it work with my page builder?
Yes. Use the shortcode, or add data-catr-catalog="ID" to any button or link from your theme or page builder.
How do I style the download button?
The shortcode outputs a plain button that inherits your active theme's button styling, so it matches the rest of your site. Add your own CSS class with the class attribute if you want.
更新日志:
1.3.0.1
- New: a cleaner admin. Every screen sits in one frame with a side menu that folds to icons on small laptops and becomes a row on phones; notices from other plugins stay above it; Settings has tabs and a save bar.
- New: the form editor shows a page of your own site beside the controls, with the form open as visitors get it, at desktop, tablet or phone size.
- New: Catalogs lists each catalog with copy buttons for its shortcode and its attribute, and you can drop a PDF on the page or choose it with the keyboard.
- New: when a request could not be emailed to you (the mail failed or the hourly limit was reached), the Catalogs screen says so in red.
- New: the Email tab warns about addresses that would not be used, and about sending to the visitor's address.
- Changed: deleting the plugin now also deletes its private folder of PDFs, but only when it deletes the catalogs (never while Catalog Rocket Pro keeps them). Files in the Media Library are never touched.
- Fixed: saving the form while Catalog Rocket Pro was deactivated or its license had lapsed removed the Pro settings (design, how to ask, field widths and conditions). They are now kept as they were.
- Fixed: on a multisite network, a site added after the plugin was network-activated had no key to sign download links. The key is now created when it is first needed.
- Fixed: a PDF larger than your hosting accepts says so, with the size allowed, instead of asking for a PDF; a title over 255 characters is refused instead of being reported as created.
- Fixed: two different PDFs with the same file name can belong to two catalogs; only the same Media Library file counts as a duplicate.
- Fixed: Delete selected appears when catalogs are ticked; View PDF works while editing and opens a fresh link; a catalog whose file is missing is marked in the list.
- Fixed: Turnstile loads only where the download form is on, needs both keys, and the secret key is checked with Cloudflare when you save. Visitors whose blocker stops it are told what to do.
- Fixed: downloads keep accented titles in the file name, and an expired link says what to do and links back.
- Fixed: a number field that the browser cannot read asks for a number; the thank-you message is announced to screen readers.
- New: email notifications on the model of WPForms. Choose Send to (one address or several), Subject, From name, From email, Reply to, Message and Format (HTML or plain text), with a Tags menu for every answer, the catalog, the visitor's name and email, the page, the date and each question. An empty message sends the standard summary. Forms saved before keep sending exactly the same email.
- New: the Design tab is laid out in cards, one for each part of the form, each saying what it changes.
- New: Add a field shows the questions visitors answer apart from the content they only read.
- New: the consent checkbox link can say what your site calls its privacy page.
- Fixed: the form preview now shows the whole form, however long it grows. It used to stop at a fixed height, and the last fields and the button could not be seen.
- Fixed: a form with a heading or another read-only block from Catalog Rocket Pro could not be sent.
- Fixed: a catalog button made without a link, such as a page-builder button with no URL, can now be reached with the Tab key and opened with Enter or Space, and screen readers announce it as a button. When the download form closes, focus goes back to that button.
- Fixed: the download form opens above everything else on the page. A cookie notice or a chat button could cover its button until the visitor dealt with them. Older browsers without popover support keep the previous behavior.
- New: a download form. Visitors fill it in before a catalog downloads, and each request arrives by email with every answer. Replying writes to the visitor.
- New: form builder under Catalogs → Download form, with the basic field types, drag-and-drop or keyboard ordering, required fields, help text, your own texts and button color, and a live preview.
- New: spam protection for the form, with a hidden trap field, a per-visitor limit and optional Cloudflare Turnstile. A new setting says whether the site sits behind a proxy such as Cloudflare, so the limit counts real visitors.
- On sites that already had catalogs, the form starts switched off, so downloads work as before until you turn it on.
- Changed: download links now always last 30 minutes. The download counter, bulk import, the catalog list export and the link duration setting are now part of Catalog Rocket Pro.
- The download script no longer loads jQuery on your pages.
- Fixed: "View PDF" on the Catalogs screen did not open PDFs that were uploaded, or whose public copy was removed. It now opens every catalog through a signed link. The "Copy URL" button, which copied a file name or the public copy's address, is gone; the shortcode and the attribute are still one click to copy.
- Fixed: editing a catalog whose PDF was uploaded turned its file name "catalog.pdf" into "http://catalog.pdf". File names changed that way are repaired on update. The files themselves were never affected.
- If a cached page was built before the form was turned on, a click on a download button now asks to reload the page instead of reporting empty fields.
- Fixed: after a site moves to another server, downloads keep working. Each PDF is found under the new uploads folder and its record is repaired; "Remove public copy" and deleting a catalog find the file there too.
- Fixed: if Catalog Rocket Pro 1.0.21.1 or later was deleted with the choice to keep your catalogs, deleting the free edition afterwards now keeps them too.
- Fixed: deleting the free edition while Catalog Rocket Pro is installed no longer resets the link expiry setting the two editions share.
- Tested with WordPress 7.1.
- Fixed: on catalogs created before 1.1.19, "Remove public copy" deleted the Media Library file the catalog was still using, so its download stopped working. The file is now copied into the private folder first, and if that copy cannot be made, nothing is deleted.
- PDFs you upload are now stored privately, in a folder with an unguessable name, and served only through the signed link. Until now the file kept the public URL it had in your Media Library.
- "Upload PDF" now uploads straight into that private store, so no public copy is ever created.
- Importing from the Media Library still works: the file is copied into the private store and the catalog row tells you a public copy is left behind, with a button to remove it when you choose. Nothing is deleted on your behalf.
- Uploads are checked to be real PDFs, not just files named .pdf.
- Deleting a catalog now also removes its private file.
- Fixed: on sites with page caching, the download button could stop working until the cache was cleared. The button no longer relies on a security token that expires inside the cached page. Downloads are still served through the same signed, expiring links.
- Added a Settings link to the plugin's row on the Plugins screen for quicker access.
- Added a dismissible upgrade banner on the Catalogs screen that highlights Catalog Rocket Pro's lead capture. "Not now" hides it for two weeks.
- Improved the review request with clearer choices (leave a review / not now / already did) and a support link.
- Creating a catalog now correctly says "Catalog created" (it previously said "updated").
- Actions that fail (save, delete, load) now show an error instead of doing nothing silently, and the list no longer gets stuck on "Loading…".
- Bulk import: the "Create" button is hidden when nothing is pending (no "Create 0 catalogs"), and the queue is locked while it runs.
- The download button is hardened against double-clicks (which could open duplicate tabs), and the download counter only counts a real, served file.
- Updated "Tested up to" to WordPress 7.0.
- Hardened downloads: signed-link handling now enforces strict path containment and fails closed if a file resolves outside the protected catalog folder.
- Added compatibility guards so the plugin degrades safely instead of erroring on unexpected environments.
- Schema migration now runs automatically on update to keep the catalogs table current.
- Improved multisite compatibility.
- Fixed: "Tested up to" now reports a valid WordPress version.
- Fixed: on some browsers the catalog download could be blocked by the pop-up blocker; the download now opens reliably.
- Added a friendly review request after two weeks of use.
- Added an in-plugin overview of Catalog Rocket Pro features on the Catalogs screen.
- Initial release.
