AntiDoubleClick

AntiDoubleClick

A user double-clicks "Create" and you end up with two orders. Someone double-clicks "Add line" and the invoice gets the same line twice. A nervous click on "Send" and the customer receives the email twice. Dolibarr has no built-in protection against this (see upstream issue #25902) — this module fixes it once and for all, on every screen.

How it works

• Forms — after the first submit, the form is locked and its submit buttons are disabled: any further click or Enter key is ignored until the page reloads.
• Action buttons — link-style action buttons (Validate, Clone, Delete…) are locked after the first click, with a visual feedback (button greyed out).
• Safety timeout — if the page does not reload (PDF/Excel export in a new tab, submit refused by a JS validation…), the lock is automatically released after a configurable delay (4 s by default).

Designed for Dolibarr

• 100% client-side: no core file modified, no PHP action, no database table. Enable the module and it works everywhere, including inside popups and confirmation dialogs.
• Careful implementation: buttons are disabled after the request is on its way, so the button name still reaches the server and the Dolibarr action fires normally.
• Compatible with all standard and custom modules screens.

Configuration

• Protect forms: on/off
• Protect action buttons: on/off
• Safety timeout (ms)
• Debug traces in the browser console
• Exclude any specific form or link by giving it the CSS class antidoubleclick-ignore

Requirements

• Dolibarr 19.0 or higher (tested up to V23)
• PHP 7.4 or higher, JavaScript enabled
