Blank screen after trying to modify layout in Admin

[Portman]

Hi,

I have been playing around with PI files to get the products page to do want I want - and had got it all (or mostly) doing what I want so went into admin to play around with the layout (Admin->Modules-Layout). when I try to change any of the modules setting and then save it I get a blank screen ... I looked in the error log for admin and the only error I can find that may be relevant is this one;

Code: Select all

PHP Warning:  Cannot modify header information - headers already sent by (output started at .../includes/modules/pi/product_info/tpl_pi_buy_button.php:33) in .../includes/system/versioned/1.0.8.5/href.php on line 195

this is the same error that comes up regardless of which module I modify
/includes/modules/pi/product_info/tpl_pi_buy_button.php is unmodified, though I do have a bunch of modified files including this one in the templates/override/... folders.

I do not know if there is something wrong with one of these files - I'll put the tpl_pi_buy_button.php file from the override folder below incase that is the issue...

Code: Select all

<?php

	if ( isset($_SESSION['customer_id']) && defined('MODULE_STORE_WHOLESALE_STATUS') && MODULE_STORE_WHOLESALE_STATUS == 'True'  && isset($_SESSION['wholesale_group']) && $_SESSION['wholesale_group'] > '0' ) { 
		
		$products_ws_price = $GLOBALS['product']->get('ws_price_' . $_SESSION['wholesale_group'] );

	if ( $products_ws_price > 0 ) { 
  ?>


<div class="col-sm-<?= (int)PI_BUY_CONTENT_WIDTH ?> pi-buy-button mt-2">

  <?=  
    new Button(PI_BUY_BUTTON_TEXT, 'fas fa-shopping-cart', 'btn-success btn-block btn-lg btn-product-info btn-buy', [
      'data-has-attributes' => (int)$GLOBALS['product']->get('has_attributes'),
      'data-in-stock' => (int)$GLOBALS['product']->get('in_stock'),
      'data-product-id' => (int)$GLOBALS['product']->get('id'),
    ]),
    new Input('products_id', ['value' => (int)$GLOBALS['product']->get('id')], 'hidden');
		
  ?>
</div>
<?php	}
	if ( $products_ws_price == 0 ) { 
?> 
	   <div class="col-sm-<?= (int)PI_BUY_CONTENT_WIDTH ?> alert alert-warning text-center">
		<?php echo PI_BUY_NA_TEXT;?> 
		</div>	
<?php 
	}

	} ?>
<?php

L33 of that code is;

} ?>
<?php

Paste the code from the core file.

It’s probably the pi/layout module install/uninstall bug fixed in 1.0.8.21.

1.0.8.21 has not yet been publicly released but has been released early to VIP PRO members. That is one of the many benefits of VIP PRO membership

Try changing by simply removing the ?> and <?php

I think this is an addon, right? Some wholesale mod?
Or is it something you have made yourself?

[Portman]

Thanks for your help @burt ... it is an original mod I wrote to work with a wholesale mod...

I actually found the error and it had nothing to do with the code, I accidently uploaded this template file into includes/modules/pi/product_info (not the template folder) and this is what was causing the error - so matter what I changed with the file in the override folder the error kept coming up

Anyway, slightly embarrassingly I will slink away now.....

We've all done something like that. Even the "experts".
Take the time I was working (on a test shop) in admin, and nothing was changing front end.
Took me a while to work out I'm in the admin of 1 test shop and the shopside of a different test shop.
