I’m very grateful for the response, my confusion comes from the fact that when I move databases between, local, dev, staging and production, the Mail data tab is only populated on the site where it was added. So whilst the form content exists across the board, the mail tab is empty on all sites apart from the site where the duplicated database came from, this causes any submissions to fail. This means that every time I move databases, I need to manually re-add the mail tab data. Why does this happen? Is there a workaround?

To further illustrate; The client is currently populating content on dev, when they let me know I download the database, find/replace the URL and then import to production. This works perfectly, apart from the mail tab is empty on production. It’s populated and works on dev, but is empty on production. This means that following import, I must then log-in and manually re-add all the mail tab data.

Here’s the complete solution which you’d add to functions.php:

function crop_settings_api_init() {
	// Add the section to media settings
	add_settings_section(
		'crop_settings_section',
		'Crop images',
		'crop_settings_callback_function',
		'media'
	);
	// Add the fields to the new section
	add_settings_field(
		'medium_crop',
		'Medium size crop',
		'crop_medium_callback_function',
		'media',
		'crop_settings_section'
	);
	add_settings_field(
		'large_crop',
		'Large size crop',
		'crop_large_callback_function',
		'media',
		'crop_settings_section'
	);
	register_setting( 'media', 'medium_crop' );
	register_setting( 'media', 'large_crop' );
} // crop_settings_api_init()

add_action( 'admin_init', 'crop_settings_api_init', 1 );

// Settings section callback function
function crop_settings_callback_function() {
    echo '<p>Choose whether to crop the medium and large size images</p>';
}
// Callback function for our medium crop setting
function crop_medium_callback_function() {
	echo '<input name="medium_crop" type="checkbox" id="medium_crop" value="1"';
    $mediumcrop = get_option( "medium_crop");
    if ( $mediumcrop == 1 ) {
        echo ' checked';
	}
	echo '/>';
	echo '<label for="medium_crop">Crop medium to exact dimensions</label>';
}
// Callback function for our large crop setting
function crop_large_callback_function() {
	echo '<input name="large_crop" type="checkbox" id="large_crop" value="1"';
    $largecrop = get_option( "large_crop");
    if ( $largecrop == 1 ) {
        echo ' checked';
	}
	echo '/>';
	echo '<label for="large_crop">Crop large to exact dimensions</label>';
}

I’ve also created a gist here and will, when time permits, create a plugin.

Thanks again for your help @bcworkz!

Hello again, so I’ve managed to do this:

function crop_settings_api_init() {
	// Add the section to media settings
	add_settings_section(
		'crop_settings_section',
		'Crop images',
		'crop_settings_callback_function',
		'media'
	);
	// Add the fields to the new section
	add_settings_field(
		'medium_cropping',
		'Medium size crop',
		'crop_medium_callback_function',
		'media',
		'crop_settings_section'
	);
	register_setting( 'media', 'medium_cropping' );
} // crop_settings_api_init()

add_action( 'admin_init', 'crop_settings_api_init' );

// Settings section callback function
function crop_settings_callback_function() {
    echo '<p>Choose whether to also crop the medium size image</p>';
}
// Callback function for our medium crop setting
function crop_medium_callback_function() {
	echo '<input name="medium_crop" type="checkbox" id="medium_crop" value="1"' . checked( 1, get_option( 'medium_crop' )) . '/>';
	echo '<label for="medium_crop">Crop medium to exact dimensions</label>';
}

Visually, this looks exactly as I want it. However I now need to make it work. How do I now combine it with…

if ( get_option( "medium_crop") !== false ) {
    update_option("medium_crop", "1");
} else {
    add_option("medium_crop", "1");
}

…to create the full hack?

NB. I’ve called the settings field medium_cropping, however the existing option is called medium_crop, have I done the right thing here?

Thanks for your help on this @bcworkz I can how what you’re proposing would work, but my ideal solution would be to add a checkbox to the settings/media page that simply updates the medium_crop option. Nice and clean.

I’m now thinking one possible solution would be to add an additional checkbox underneath the Medium dimensions in the dashboard, replicating the layout of Thumbnail where there’s an option to “Crop thumbnail to exact dimensions”. Does anyone know how we could combine the above code with what I’m proposing here?
