Smarty：如何在模板中包含 php？

Question

I've tried {include_php file="phpfile.php"} and {php} tags but both cause deprecated error. Can you not do this in Smarty anymore? I can't find anything in the docs.

Answer 1

I circumvented this problem. Create a plugin file named block.php_code.php with this function in it:

function smarty_block_php_code($params, $content, &$smarty)
{
    if (is_null($content))
    {
        return;
    }
    if ('<?php' == substr($content,0,5) && '?>' == substr($content, -2))
        $content = substr($content,5,-2);
    ob_start();
    eval($content);
    return ob_get_clean();
}

In your template, you can then write:

{php_code}{literal}<?php

    print "Hello, world!";

?>{/literal}{/php_code}

Answer 2

They are depreciated for a reason as they allow poor practices. Smarty recommends putting the included script into the PHP logic or creating a plugin (which is simple).

{php} tags are deprecated from Smarty, and should not be used. Put your PHP logic in PHP scripts or plugin functions instead.

{include_php} is deprecated from Smarty, use registered plugins to properly insulate presentation from the application code.

If you include what you are trying to do in your phpfile.php , we can help you write a plugin function.

{include_php} is marked as deprecated in both Smarty2 and 3; {php} in Smarty3 only:
