help: sprintf & plugins
I am creating a plugin that is using sprintf and a “format” parameter so that the user can override the default language & formatting settings. For example:
<span style=“line-height:20px”>‹txp:abc_plugin format="There are %d monkeys in the %s" /› =>There are 10 monkeys in the trees‹txp:abc_plugin format="The %2\$s contain %1\$d monkeys" /› =>The trees contain 10 monkeys
In the first example it works fine, but for some reason in the second example, when passing the format as a parameter, sprintf doesn’t like the value and only outputs “The $s contains $d monkeys”, rather than parsing the string and replacing the values. I’ve tested to make sure the function would work correctly in all other circumstances and it definitely has something to do with what is received by sprintf that it doesn’t like. The plugin function appears to be receiving the correct string format as a parameter.
Do any php geeks out there have any idea what could be going wrong? Is this a datatype issue?

Re: help: sprintf & plugins
As a more specific example…
Tag used in form: ‹txp:abc_plugin format="The %2\$s contain %1\$d monkeys" /›
(and now from within the plugin function)
<pre>
function abc_plugin($atts) {
...
echo $format;
echo sprintf($format,10,'trees');
echo sprintf("The %2\$s contains %1\$d monkeys",10,"trees");
...
}
</pre>
Result:
The %2\$s contains %1\$d monkeys
The $s contains $d monkeys
The trees contains 10 monkeys

Re: help: sprintf & plugins
It’s so strange because the two strings are identical, yet md5’ing them yields different results and they are not equal via ==. is_string() checks out for both… copying and pasting show the same strings… is some character getting converted?

Re: help: sprintf & plugins
strcmp("The %2\$s contains %1\$d monkeys", $format) => -56
$format => "The %2\$s contains %1\$d monkeys"
?!

Re: help: sprintf & plugins
Ok, so:
var_dump("The %2\$s contains %1\$d monkeys") => string(30)
var_dump($format) => string(32)
It’s gotta be something about the backslashes…

GOT IT
Phew. So you’ve got to leave out the escaping backslash if using this format via plugin parameter, such as:
‹txp:abc_plugin format="The %2$s contain %1$d monkeys" /›
Man, it’s lonely talking to oneself…
