haylau Posted July 12, 2021 Share Posted July 12, 2021 Hi Been using M4PDF module for sometime with TB and all has been well. Although it is not officially supported and the developer has no intention of working with ThirtyBess, I am hoping someone here could help The latest module works fine with Prestashop 1.6, so definitley a discrepancy between TB and PS 1.6 When trying to create a "debug" report in the module whch basically creates a PDF document containing all the variables that can be used withing the PDF system, I get the following error Decoded exception Using $this when not in object context in file vendor/smarty/smarty/libs/sysplugins/smarty_internal_debug.php at line 310 Source file: vendor/smarty/smarty/libs/sysplugins/smarty_internal_debug.php 291: if ($varvalue === true) { 292: $tpl_vars[ $key ][ $varkey ] = $varvalue; 293: } 294: } else { 295: if ($varkey !== 'scope' || $varvalue !== 0) { 296: $tpl_vars[ $key ][ 'attributes' ][ $varkey ] = $varvalue; 297: } 298: } 299: } 300: } 301: if ($obj->_isTplObj()) { 302: $tpl_vars[ $key ][ 'scope' ] = $obj->source->type .

haylau Posted July 13, 2021 Author Share Posted July 13, 2021 (edited) This is the tpl file making the call when the error occurs, and i think it is the first line causing the issue.

datakick Posted July 13, 2021 Share Posted July 13, 2021 I believe the problem might be in modules/m4pdf/classes/M4Object.php 1772: if (version_compare(_PS_VERSION_, '1.7.4.0', '>=')) { 1773: $sid = new Smarty_Internal_Debug(); 1774: $ptr = $sid->get_debug_vars($smarty); 1775: $template_data = $sid->template_data; 1776: } else { 1777: $ptr = Smarty_Internal_Debug::get_debug_vars($smarty); 1778: $template_data = Smarty_Internal_Debug::$template_data; 1779: } The code expects that PS < 1.7.4.0 comes with old smarty library. Thirtybees updated smarty library to new version, so this expectation is not valid. Try to change this code to 1772: if (defined('_TB_VERSION_') || version_compare(_PS_VERSION_, '1.7.4.0', '>=')) { 1773: $sid = new Smarty_Internal_Debug(); 1774: $ptr = $sid->get_debug_vars($smarty); 1775: $template_data = $sid->template_data; 1776: } else { 1777: $ptr = Smarty_Internal_Debug::get_debug_vars($smarty); 1778: $template_data = Smarty_Internal_Debug::$template_data; 1779: } It might help. Or not 🙂 Link to comment Share on other sites More sharing options...
haylau Posted July 13, 2021 Author Share Posted July 13, 2021 Thanks for taking look. And great to have you back around again, hope you are doing well. That code made a difference, it stops the 500 error. But still not brining down the data. It shows all as NULL BUT it should look like this - so guess it is a more complex issue Link to comment Share on other sites More sharing options...
datakick Posted July 13, 2021 Share Posted July 13, 2021 Please send me the module in zip file + information how to reproduce the issue, I will look into that. It will be something trivial, probably just wrong instance of $smarty being used to get variables 1 Link to comment Share on other sites More sharing options...
