Certificate Verifier WordPress Plugin

A WordPress plugin that allows organizations to manage and verify certificates. Users can add certificates individually or bulk import via CSV, while visitors can verify certificates using a simple verification form.

Features

• Add individual certificates with details:

  • Name
  • Email
  • Certificate Number
  • Issue Date

• Bulk import certificates via CSV

• Export all certificates to CSV

• Edit existing certificates

• Delete certificates

• Public certificate verification via shortcode

• Responsive, modern UI

• Secure data handling with input sanitization

Installation

WordPress needs the zip to contain the plugin folder at the top level (not the whole repo). Use one of these:

Option A – Create the zip from the repo (recommended)
From the project root (the folder that contains certificate-verifier/), run:

zip -r certificate-verifier.zip certificate-verifier/

Upload certificate-verifier.zip in WordPress (Plugins → Add New → Upload).

Option B – Manual

1. Zip only the certificate-verifier folder (the one that contains certificate-verifier.php).
2. Do not zip the whole wordpress-certificate-verifier-plugin project; that layout causes "No valid plugins were found."

Then: Plugins → Add New → Upload Plugin → Choose the zip → Install Now → Activate.

Public Certificate Verification

Add the verification form to any page or post using the shortcode:

[certificate_verifier]

This will display a form where users can enter a certificate number to verify its authenticity.

CSV Format

When importing certificates via CSV:

1. The first row should contain column headers
2. Required columns:
   • Name
   • Email
   • Certificate Number
   • Issue Date (YYYY-MM-DD format)
