Print all variables available in a Smarty template
提问by Lorenzo
How do you print all variables available in the context of a Smarty template? Something like the Django debug trace that lists everything being passed.
如何打印 Smarty 模板上下文中可用的所有变量？类似 Django 调试跟踪的东西，它列出了所有被传递的内容。
Thanks
谢谢

Use {debug}From the manual:
使用{debug}手册：
{debug}dumps the debug console to the page. This works regardless of the debug settings in the php script. Since this gets executed at runtime, this is only able to show the assigned variables; not the templates that are in use. However, you can see all the currently available variables within the scope of a template.
{debug}将调试控制台转储到页面。无论 php 脚本中的调试设置如何，这都有效。由于这是在运行时执行的，因此只能显示分配的变量；不是正在使用的模板。但是，您可以在模板范围内看到所有当前可用的变量。
$debugging = truemust be enabled in your settings or class, and site popups must be unblocked to see the window
$debugging = true必须在您的设置或课程中启用，并且必须取消阻止站点弹出窗口才能看到该窗口

$all_tpl_vars = $smarty->getTemplateVars();
回答by Louis Ferreira
$all_tpl_vars = $smarty->getTemplateVars(); var_dump($all_tpl_vars);
$all_tpl_vars = $smarty->getTemplateVars(); var_dump($all_tpl_vars);
//before pushing to the template
//在推送到模板之前
