using a variable inside do_shortcode()
-
Hi,
i’m trying to have custom shortcode nested in a plugin shortcode.
i learned that there is some limitation to WP shortcodes and to over come it I need to us the do_shortcode functioni used this in my function file
$childrens = do_shortcode(‘[products ids=”$string”]’);
based on some research I tried:
$childrens = do_shortcode(‘[products ids=”.’$string’.”]’);
and this
$childrens = do_shortcode(‘[products ids=\’$string’\]’);
with no success.in my custom template i can see the correct output for the $string variable using echo $string results in “41,402” so i know it works ok
when i use
$childrens = do_shortcode(‘[products ids=”41,402″]’);
i can see the desired behavior rendered on the page
when i use
$childrens = do_shortcode(‘[products ids=”$string”]’);
i get all the results for the [products} shortcode as it ignore the $string variable.any thoughts?

The shortcode inside
do_shortcode()is a String, so needs to be wrapped in'or".To output a variable inside a string, you need to close the
'quote marks, use.to append to the string, then put the variable, before opening the string again and completing the shortcode:$childrens = do_shortcode( '[products ids="'. $string . '"]' );
It’s also possible to just put a variable string if you use double quotes:
$string = "This is $variable";
But since shortcodes already contain double quotes you would need to escape them with
\:$childrens = do_shortcode( "[products ids=\"$string\"]" );
Another option is to use sprintf(), which can be used to substitute a placeholder in a string with a variable:
$childrens = do_shortcode( sprintf( '[products ids="%s"]', $string ) );
