We have another request on 8302777-zd-a8c

This one was for the WPVivid plugin, which requires curl PHP extension.

Another report here: 8350827-zd-a8c

The user was trying to use the WPVivid plugin as well, which requires curl.

Recommended the AIOWPM plugin in the meantime for exporting from Studio.

Another request here: 8428094-zd-a8c

They want to be able to use the Starter Templates Plugin, but we aren't sure yet from the messaging whether cURL is required or just suggested.

[danielbachhuber]

Bumping this to high priority because it's a pretty egregious issue.

[ktyfuller604]

In this case, they are looking to develop a local plugin that uses cURL to extract data from an external CRM before deploying it to production.

Upstream issue about supporting libcurl in php-wasm: https://github.com/seanmorris/php-wasm/issues/32

[mpkelly]

I changed the status to "Needs core / 3rd party fix" as we're blocked here.

[akirk]

According to @adamziel in https://github.com/WordPress/wordpress-playground/issues/1008 curl is currently only available in the CLI.

[brandonpayton]

@mpkelly Curl support was added for @php-wasm/node in (this PR)[https://github.com/WordPress/wordpress-playground/pull/1273] and included in the v0.7.2 release.

wp-now is currently using @php-wasm/node v0.6.16, which is not built with the curl extension.

@sejas has already created a draft PR for upgrading wp-now to a newer @php-wasm/node release, saying:

It will fix WEBP images, support curl and other fixes features introduced in these versions.

It's not a straightforward upgrade as various API have been changed and, in some cases, consolidated.

A couple of options are:

1. Consider migrating Studio to using the Playground CLI if possible
2. Update wp-now to use the latest @php-wasm/node APIs

If updating wp-now, some useful reference points are:

• Playground CLI initialization
• The implementation of Playground's bootWordPress() function which ties together PHP runtime management and creation of the PHPRequestHandler

Thank you very much for your comment!!! I already found that, and started working on upgrading wp-now. I tested also spinning a site with playground-cli and found that the problem isn't there. ( And this is what made me trying to start upgrading wp-now. )

Problem is, that studio's wp-now has changes in comparison to what we have in wordpress/playground-tools repo, so it will be easier to just apply how playground-cli handle things in our wp-now version, as it's a relative small part that will be affected ( startWPNow function and how php instantiation is happening in there.).

Finally, I think that updating wp-now it will be good, as it will benefit wp-now in playground-tools repo as well ( we will apply the changes in there as well )

Thanks for mentioning and working on this! That will be great for existing wp-now users.

CURL was fixed by upgrading the Playground dependencies on https://github.com/Automattic/studio/pull/491 🥳 It will be included in Studio in the next version.

I tested it in trunk with the following code:

function sendCurlRequest($url) {
    $ch = curl_init();

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

    $response = curl_exec($ch);

    if (curl_errno($ch)) {
        echo 'Curl error: ' . curl_error($ch);
    }

    curl_close($ch);

    return $response;
}

$url = "https://api.wordpress.org/stats/wordpress/1.0/";
$response = sendCurlRequest($url);
echo $response;

[wojtekn]

It's fixed in 1.1.1.

hi,

I get this error if I try to run curl against localhost:

cURL error 55: Send failure: Socket not connected

[wojtekn]

@countfak thanks for the report. Would you mind sharing the code snippet? Did you try with 127.0.0.1 instead of localhost?

[countfak]

@wojtekn I'm getting the same error with 127.0.0.1

this is the code I'm using

$handle = curl_init('http://localhost:3000/'); // tried with 127.0.0.1 too
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_NOBODY, true);
curl_exec($handle);
echo curl_error($handle); // I see the error if I print this
curl_close($handle);

[wojtekn]

@countfak thanks for sharing the snippet!

I tested it, and I couldn't reproduce the issue with your snippet on Studio 1.1.2. It didn't show an error either for localhost or 127.0.0.1.

I also tried displaying downloaded content using another snippet, and it worked fine for me for both domain and IP:

$handle = curl_init('http://localhost:8884/license.txt'); // tried with 127.0.0.1 too
$body = curl_exec($handle);
var_dump($body);
curl_close($handle);
die;

I see your snippet uses the http://localhost:3000/ URL. It's not a Studio site URL. Is anything server under that port?

[countfak]

hey @wojtekn thanks for your help. I'm running Vite which starts its server on port 3000 (it's just a random port). I'm using it to bundle dependencies, code and assets and serve them accordingly on development. Basically what's explained over here: https://github.com/andrefelipe/vite-php-setup

maybe Studio is not able to access what lives "outside" of it?

[wojtekn]

@countfak I've checked another snippet to fetch the license file in the Studio site from the site served by Local, and it worked fine:

$handle = curl_init('http://test-api.local/license.txt');
$body = curl_exec($handle);
var_dump($body);
curl_close($handle);
die;

[countfak]

This remains a mystery.

I always get cURL error 55: Send failure: Socket not connected if I try to use curl to get something on localhost that is not served by Studio.

In my case, since I just need to return true or false whether I'm on localhost or not, I ended up doing a simple check on $_SERVER['HTTP_HOST'].
