ecshop template: How to make constants referenceable in ecshop templates

For example, $smarty.const.'constant' cannot be used.
In fact, the template engine is not complicated in principle. It just replaces some template tags with functions, variables, and grammatical structures in PHP.
To add the function of reference constants to the ecshop template this time, just add two lines of code to the function make_var()

Copy the code The code is as follows:

function make_var($val)
{
if (strrpos($val, '.') === false)
{
if (isset($this->_var[$val]) && isset($this->_patchstack[$val]))
{
$val = $this->_patchstack[$val];
}
$p = '$this->_var['' . $val . '']';
}
else
{
$t = explode('.', $val);
$_var_name = array_shift($t);
if (isset($this->_var[$_var_name]) && isset($this->_patchstack[$_var_name]) )
{
$_var_name = $this->_patchstack[$_var_name];
}
if ($_var_name == 'smarty')
{
if($t[0] == 'const'){
return strtoupper($t[1]);
}
$p = $this->_compile_smarty_ref($t);
}
else
{
$p = '$this->_var[''' . $_var_name . '']';
}
foreach ($t AS $val)
{
$p.= '['' . $val . '']';
}
}
return $p;
}

Lines 21-23 are newly added, which allows you to reference the constants defined in php through {$smarty.const.const} in the template file

Copy the code The code is as follows:

21 if($t[0] == 'const'){
22 return strtoupper($t[1]);
23 }

The above introduces the implementation method of making constants referenceable in ecshop templates in ecshop templates, including the content of ecshop templates. I hope it will be helpful to friends who are interested in PHP tutorials.
