WordPress file is not uploading in theme settings

0 Views

So I’m building my own WordPress theme and I included a setting to be able to change the sites logo.

This is the part that registers the function that handles the upload:

add_settings_field("logo", "Logo", "logo_display", "theme-options", "section");
register_setting("section", "logo", "handle_logo_upload");

This is the handler function that is supposed to handle the file given: 

function handle_logo_upload()
{
    if ( ! function_exists( 'wp_handle_upload' ) ) {
        require_once( ABSPATH . 'wp-admin/includes/file.php' );
        }

        $uploadedfile = $_FILES['file'];

        $upload_overrides = array( 'test_form' => false );

        $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );

        if ( $movefile && !isset( $movefile['error'] ) ) {
            echo "File is valid, and was successfully uploaded.n";
            var_dump( $movefile);
        } else {
            /**
             * Error generated by _wp_handle_upload()
             * @see _wp_handle_upload() in wp-admin/includes/file.php
             */
        echo $movefile['error'];
    }

    return 'stringaz';      
}

This is what the theme panel looks like: http://pasteboard.co/uwC3Qmi.png

Here you can see that the handler is not working because a string called ‘stringaz’ is being presented where the logo should appear: http://pasteboard.co/vsnqkay.png

What do I need to change to the handler function to get this code to run?

cheers!

  1. you can try this one, its example, you should change your own variable name and all that:

    if(!empty($_FILES['user_image']["name"]))
{
    if( $_FILES['user_image']['type'] == "image/jpeg" || $_FILES['user_image']['type'] == "image/png" || $_FILES['user_image']['type'] == "image/jpg")
    {
        $wp_upload_dir = wp_upload_dir();
        $target_file = $wp_upload_dir['path']."/".$_FILES['user_image']["name"];
        $target_file1 = $wp_upload_dir['url']."/".$_FILES['user_image']["name"];
        if ( move_uploaded_file($_FILES['user_image']["tmp_name"], $target_file) )
            update_user_meta($current_user->ID, 'cupp_upload_meta', $target_file1 );
        else
            $errmsg = "Sorry, there was an error uploading your file.";
    }
    else
    {
        $errmsg = "Image file have not valid extension.";
    }
}

  2. Add enctype=”multipart/form-data” in <form> tag.
    Like <form method="post" action="options.php" enctype="multipart/form-data">

    function handle_logo_upload()
{
    if(!function_exists('wp_handle_upload')){
        require_once(ABSPATH.'wp-admin/includes/file.php');
    }
    if(!empty($_FILES["logo"]["tmp_name"]))
    {
        $urls = wp_handle_upload($_FILES["logo"], array('test_form' => FALSE));
        $temp = $urls["url"];
        return $temp;   
    }
    return $option;
}

    It’s Done! 🙂
