Website instructions:

Create a customized copy of   includes/templates/custom/templates/tpl_product_info_display.php  (from  includes/templates/template_default/templates/tpl_product_info_display.php) 

You will be defining your boilerplate strings in a file  called includes/languages/english/extra_definitions/my_defines.php   Each string will have a PHP "define" statement, and all the strings will be listed in an array.  In this way,  users can simply add and delete strings by editing this one file, rather than having to dig into the internals of Zen Cart. 

We'll use a simple example:  
<?php  $descr_stringlist = array("PHP_ONE_WEEK_DELAY", "PHP_TWO_WEEK_DELAY", "PHP_THREE_WEEK_DELAY");   define('PHP_ONE_WEEK_DELAY', 'These decals will be shipped in one week after receiving your order.');  define('PHP_TWO_WEEK_DELAY', 'These decals will be shipped in two weeks after receiving your order.');  define('PHP_THREE_WEEK_DELAY', 'These decals will be shipped in three weeks after receiving your order.');   ?>   
We've defined three constants and added each one to a list called descr_stringlist. 

Now go back to  includes/templates/custom/templates/tpl_product_info_display.php   Change   <!--bof Product description --> <?php if ($products_description != '') { ?> <div id="productDescription" class="productGeneral biggerText"><?php echo stripslashes($products_description); ?></div> <?php } ?> <!--eof Product description -->   to 
  <!--bof Product description --> <?php if ($products_description != '') { ?> <div id="productDescription" class="productGeneral biggerText"> <?php  $stripped_products_description = $products_description; foreach ($descr_stringlist as $varname) {     $stripped_products_description = str_replace($varname, constant($varname), $stripped_products_description); } ?> <?php echo stripslashes($stripped_products_description); ?></div> <?php } ?> <!--eof Product description -->   

For reasons long forgotten, but after a lot of experimentation, I ended up locating the file in
\includes\languages\english\extra_definitions\boilerplate_text.php

and using this format

$GLOBALS['boilerplate_array'] = [
'ATEQ_TPMS_UPDATE',
'ATEQ_TPMS_COMPANY', etc...
]

I use a function with this to do the replacement where necessary.

In Zen Cart 1.5.8, you have to global the stringlist explicitly.

$descr_stringlist = array("PHP_ONE_WEEK_DELAY", ...
$GLOBALS['descr_stringlist'] = $descr_stringlist;

@swguy

Thank you for the updated code for this small module and ran perfectly without any debug files. :smile:

includes/languages/english/extra_definitions/YOUR_TEMPLATE/my_defines.php ```html
$descr_stringlist = array("PHP_ONE_WEEK_DELAY", "PHP_TWO_WEEK_DELAY", "PHP_THREE_WEEK_DELAY");
$GLOBALS['descr_stringlist'] = $descr_stringlist;
define('PHP_ONE_WEEK_DELAY', 'Notice this unique species of Horned Lizards is only found in these general areas, which is shown on the left in this regional map.');
define('PHP_TWO_WEEK_DELAY', 'These decals will be shipped in two weeks after receiving your order.');
define('PHP_THREE_WEEK_DELAY', 'These decals will be shipped in three weeks after receiving your order.');

?>

This is an artifact of the way language files are processed in 1.5.8. I will add it to the release specific upgrade considerations on next checkin.
