Hi bot, im using dompdf and when I generete pdf through htttps the image is not loaded. What is the reason?

There could be a few reasons why the image is not loaded when generating a PDF with dompdf over HTTPS. Here are a few things you can check:

1. SSL Certificate: Make sure that the SSL certificate on your server is valid and properly installed. If there is an issue with the SSL certificate, it may prevent the image from loading.

2. Image URL: Ensure that the image URL you are using in the HTML is correct and accessible over HTTPS. Sometimes, the image URL may be specified with an HTTP protocol, causing the browser to block it due to mixed content rules.

3. Relative vs Absolute Paths: Ensure that the image URL is specified correctly as either a relative or absolute path. If it's a relative path, make sure it is relative to the location of the HTML file generating the PDF. If it's an absolute path, ensure that it is correct and accessible.

4. File Permissions: Check if the image file has appropriate permissions set on the server. Make sure that the web server has enough permissions to read the image file.

5. Content Security Policy (CSP): If your website has a Content Security Policy in place, it may be blocking the image from loading. Review your CSP configuration and ensure that it allows images from the specified source.

6. SSL Certificate Chain: In some cases, if the SSL certificate chain is incomplete or not properly configured, it may cause issues with loading resources over HTTPS. Check if your SSL certificate chain is complete and correctly configured.

By checking these potential issues, you should be able to identify the reason why the image is not loading when generating the PDF with dompdf over HTTPS.

Is there any php code to work it on https?

Is there any php code to work it on https?

To ensure that your dompdf code works properly with HTTPS, you need to make sure that you are using secure URLs for your images and set the appropriate options in dompdf. Here's an example PHP code snippet that demonstrates how to generate a PDF with dompdf over HTTPS:

<?php
require_once 'dompdf/autoload.inc.php';

use Dompdf\Dompdf;

// Create a new instance of Dompdf
$dompdf = new Dompdf();

// Enable or disable the use of SSL for the image URLs
$dompdf->setHttpContext(
    stream_context_create([
        'ssl' => [
            'verify_peer'      => true,
            'verify_peer_name' => true
        ]
    ])
);

// Load HTML content
$html = '<html><body><img src="https://example.com/image.jpg"></body></html>';
$dompdf->loadHtml($html);

// (Optional) Set paper size and orientation
$dompdf->setPaper('A4', 'portrait');

// Render the HTML as PDF
$dompdf->render();

// Output the generated PDF to the browser
$dompdf->stream('document.pdf', ['Attachment' => false]);
?>

In the code snippet above, the key part is setting the verify_peer and verify_peer_name options to true in the ssl context. This enables dompdf to validate the SSL certificate for the image URL over HTTPS. Replace 'https://example.com/image.jpg' with the actual URL of your image.

By using this code, you can generate a PDF with dompdf over HTTPS, and the image should be loaded successfully.

I tried but not working

I apologize for the confusion. If the previous code snippet did not work for you, here are a few additional troubleshooting steps you can try:

1. Check the image URL: Ensure that the image URL is correct and accessible. You can test the URL by directly accessing it in a web browser. Make sure that the image is loading without any issues.

2. Check for SSL certificate errors: If the image URL is using HTTPS, verify that the SSL certificate is valid and properly installed on the server. If there are any SSL certificate errors, it may prevent the image from loading. You can use online SSL certificate validators to check the validity of the certificate.

3. Verify PHP configuration: Confirm that the PHP installation on your server is configured with the necessary SSL/TLS support. Ensure that the OpenSSL extension is installed and enabled in your PHP configuration.

4. Enable error reporting: Temporarily enable error reporting in your PHP script to see if any error messages are being generated. This can help identify any specific errors that are occurring.

5. Test with a local image: Try using a local image file instead of an external URL. This can help determine if the issue is specific to the image URL or if there is a more general issue with your dompdf setup.

6. Check server permissions: Ensure that the web server has appropriate permissions to access the image file. Verify that the file permissions allow the web server to read the image file.

7. Update dompdf and dependencies: Make sure you are using the latest version of dompdf and its dependencies. Check for any known issues or bug fixes related to image loading in the release notes or issue tracker.

By going through these troubleshooting steps, you should be able to identify the cause of the image not loading in your dompdf-generated PDF over HTTPS.
