Ask experts to answer questions about smarty

I have imported an advertisement file in the smarty template, but I do not know whether the advertisement file exists. if the file does not exist, an error will be reported. how can I not report an error, (Note: I do not want to use assign to pass parameters. because there are many ad files, I cannot determine whether the files exist one by one in the PHP file.) some code in the smarty template is as follows: & lt; div & ask experts to answer questions about smarty
I imported an advertisement file into the smarty template, but I don't know whether the advertisement file exists. if the file does not exist, an error will be reported. how can I avoid an error? (note: I don't want to use assign to pass parameters. because there are a lot of ad files, it is impossible for me to determine whether there is a parameter in the PHP file one by one)

Some code in the smarty template is as follows:
<{Include file = ".../../include/menu_tags_up_button.inc"}>

Error:
Warning: Smarty error: unable to read resource: ".../include/menu_tags_up_button.inc" in .....


As described above, if ".. /.. if the/include/menu_tags_up_button.inc file does not exist, an error will be reported. of course, there will be no problems, so please answer them [color = # FF00FF] [/color]

------ Solution --------------------
Are you sure the file path is correct? since the program says it cannot read the file, or the file does not exist, or the path is wrong for me, what is the problem?
------ Solution --------------------
The smarty error you see is not the php error ?? The smarty throws an exception that is also handled by php. isn't smarty written in php ??
If you do not want to report an error, set the display_error... configuration of php.
------ Solution --------------------
You can check the smarty manual to see if there are any implementation methods. if you are in trouble, you can directly go to the template.
Nested php script

{Php}

If (file_exists (path) {include (path );}

{/Php}
