Hello,

After posting the comment, there is an issue requiring allow_url_fopen to be enabled in php.ini. Is it really necessary?

• WP: 6.1.1

[12-Feb-2023 20:28:40 UTC] PHP Warning:  file_get_contents(data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQAB...

Problem is this code in /lib/NewsletterTemplates/ThumbnailSaver.php where file_get_contents() is used with a base 64 encoded data URI.

  private function saveBase64AsImageFile(string $file, string $data): bool {
    return file_put_contents($file, file_get_contents($data)) !== false;
  }

This fails on servers where data:// is disabled via allow_url_fopen setting in server configuration which seems to be the case in quite many hosting companies.

After seeing several comparable topics, like https://www.ads-software.com/support/topic/uncaught-error-call-to-undefined-function-guzzlehttpchoose_handler/ in this forum, I am posting the following report.

Since the 6.0 update of the Mollie WordPress plugin I am seeing the following PHP errors when visiting the website (hostname replaced with ‘example.com’):

AH01071: Got error 'PHP message: PHP Fatal error: Uncaught RuntimeException: GuzzleHttp requires cURL, the allow_url_fopen ini setting, or a custom HTTP handler. in /var/www/vhosts/example.com/httpdocs/content/plugins/mollie-payments-for-woocommerce/vendor/guzzlehttp/guzzle/src/functions.php:119\nStack trace:\n#0 /var/www/vhosts/example.com/httpdocs/content/plugins/mollie-payments-for-woocommerce/vendor/guzzlehttp/guzzle/src/HandlerStack.php(42): GuzzleHttp\\choose_handler()\n#1 /var/www/vhosts/example.com/httpdocs/content/plugins/mollie-payments-for-woocommerce/vendor/mollie/mollie-api-php/src/MollieApiClient.php(296): GuzzleHttp\\HandlerStack::create()\n#2 /var/www/vhosts/example.com/httpdocs/content/plugins/mollie-payments-for-woocommerce/src/Mollie/WC/Helper/Api.php(46): Mollie\\Api\\MollieApiClient->__construct()\n#3 /var/www/vhosts/example.com/httpdocs/content/plugins/mollie-payments-for-woocommerce/src/Mollie/WC/Helper/Data.php(341): Mollie_WC_Helper_Api->getApiClient()\n#4 /var/www/v...', referer: https://example.com/

Strange and incorrect, because the cURL functions in PHP are actually enabled. The allow_url_fopen function is disabled on purpose because of security reasons.

Can we use the Mollie plugin without having to allow insecure PHP settings like allow_url_fopen?

And furthermore, have you considered looking at built-in WordPress functions for these types of requests, like for example https://developer.www.ads-software.com/reference/functions/wp_remote_request/ ?

I have installed the plugin and when i try to activate the plugin i get the message below.

You need to set PHP directive allow_url_fopen = On. Please contact your web hosting company for help.

I put the allow_url_fopen = On in the php.ini but still get the same message.

Can you help me?

Thank you!

An alternative that works using curl but would be great to have it as standard.

Function:

function url_get_contents ( $url ) {

    if ( ! function_exists( 'curl_init' ) ) {
        die( 'The cURL library is not installed.' );
    }

    $ch = curl_init();

    curl_setopt( $ch, CURLOPT_URL, $url );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

    $output = curl_exec( $ch );

    curl_close( $ch );

    return $output;

}

Usage:

$remote_file_data = url_get_contents( $image_url );

Is “allow_url_fopen” required to be enabled for correct operation of the plugin ?
It doesn’t appear to be listed as a requirement in the FAQ.

The plugin appears to work and doesn’t display any errors on the settings page but I see the following warnings in my logs.

PHP Warning: file_get_contents(): https:// wrapper is disabled in the server configuration by allow_url_fopen=0 in /home/domain.com/wp-content/plugins/webp-converter-for-media/app/Settings/Errors.php on line 82

Thanks.
