Using cURL and file_get_contents

Hey guys,

I have been working on a wordpress theme for a couple of months, that I am planning to release in a week (hopefully). I have been running my theme through the theme check plugin and I see warnings for using PHP file functions (get and put) and cURL (which i use for my twitter widget).

How seriously are they issues considered by the theme reviewers, because I think cURL is good way to access remote servers and I have to use file ops to generate my dynamic CSS . Using the WP Filesystem would make it really convoluted at this point in time. I could use the HTTP API ’s as an alternative to cURL, but WP Filesystem is sure to complicate my work.

I would like have some advise passed on by experienced theme developers and the staff here at themeforest. I have an item in the mojo themes marketplace that has been quite successful and these warnings were ignored.

Always use WordPress core function if they are avaiable!

In your case: wp_remote_get()

Thanks I will change that function. But what about file_put_contents(). The themecheck plugin throws warnings for the use of this function ?

file_put_contents() might not work for your customers it depends on their hosting configuration. if you really want to store your data in a file you have to use the Filesystem API which is more complex but recommended by wordpress. or you can use the Transients API which is more reliable in this case.

function form_css() {
    header( 'Content-Type: text/css' );
    header( 'Expires: Thu, 31 Dec 2050 23:59:59 GMT' );
    header( 'Pragma: cache' );

    if ( false === ( $css = get_transient( 'mymail_form_css' ) ) ) {
        // generate your CSS here
        set_transient( 'mymail_form_css', $css );
    }

    echo $css;
    die();
}

add_action('wp_ajax_my_css', 'form_css');
add_action('wp_ajax_nopriv_my_css', 'form_css');

wp_register_style('my-css', admin_url('admin-ajax.php?action=my_css'));
wp_enqueue_style('my-css');

Btw, I have some issues with both cURL and file_get_contents(). After updating the file it should read it reads nothing for like 15 minutes. It doesn’t return NULL nor FALSE , just pretends it’s an empty file. I suppose it’s something with the buffer/server session but can’t find a solution.

Seems like this version doesn’t work on IE9 (works on IE7 +8). I’m searching for a solution to this

What doesn’t work in ie9?

I don’t know why but IE9 always tries to download the file if Content-type = text/css. With text/html I can view it in the browser but the styles doesn’t get applied to the page
