Can't use wp_footer on one page where I need a map. Any work-arounds?

[michaelnason]

Hi,

I’m using MapPress in combination with the GroupBuyingSite plugin (GBS for short – http://www.groupbuyingsite.com). I’ve integrated the plugins together pretty nicely, but there is one template that does not call wp_footer (for good reason). Maps on those pages are not displaying…yet.

Can anyone suggest any alternatives? Can I hardcode the stylesheet/script enqueues into that template? If so, what would be the best way to do that?

 

Thank you,

Michael

Hi,

Just to be clear, wp_footer() only loads scripts in the footer.  It doesn’t actually display the blog footer – that’s done by get_footer() instead.

Were you thinking of get_footer()?

If that’s not the problem and you really can’t call wp_footer(), then you could possibly just trigger action ‘wp_print_footer_scripts’ instead, e.g. do_action(‘wp_print_footer_scripts’).  That calls the internal function to queue all the scripts.

Hi Chris,

Thanks. The page I’m having trouble with is a receipt-type page that is meant to be printed. The template for this view does not call wp_footer(), and no external scripts or stylesheets are loaded.

If I add wp_footer() or do_action(‘wp_print_footer_scripts’), then my site’s stylesheet and all other scripts are loaded even though they should not be on this view (including mappress’s).

Is there a way to selectively load MapPress resources for this template, or any other way I can work around this limitation?

Hi,

I don’t think WordPress offers any way to output only specific queued scripts.

You could take a look at a normal page with a map and just copy the google/mappress script tags into your checkout page template.  Call the MapPress print_maps() function to output the map data after those tags:

<?php
global $mappress;
$mappress->print_maps();
?>

Perhaps there’s a way to conditionally not load the other scripts on the checkout page?   Or you could dequeue them before the wp_footer() call:

Thanks, I got it working!

Right now, I just copied var mappl10n from a different page with a map on it. Is that unwise? Should I dynamically generate this content? How?

[Chris]

Hi,

I assume you just copied over the script tags?  I forgot about mappl10n, though – you can output it by calling $mappress->l10n();

I still think it would be better to just deuque/deregister the scripts you don’t want, though – that way if MapPress changes you won’t need to re-do the checkout page.

$mappress->l10n(); isn’t outputting anything for me for some reason:

<?php
global $mappress;
$mappress->l10n();
$mappress->print_maps();
?>

I agree this isn’t an ideal setup, but I need to get this sorted for launch. We’ll develop a smarter way to do this soon after.

Hi, try:

echo $mappress->l10n();
