Frage
I have the following problem: I want to add print_f in an array in wordpress.
printf( __('Option to share on %s', 'themename'), 'name')
However, the following code does not work properly for me. Instead of the actual result, it throws out "30" .
$wp_customize->add_control(
new WP_Customize_Control(
$wp_customize,
'display-name'
array(
'label' => printf( __('Option to share on %s', 'theme-name'), 'name'),
'section' => 'share',
'settings' => 'display-name',
'type' => 'checkbox',
'description' => 'Just a Description.'
'active_callback' => 'share_callback',
)
)
);
Hope someone can help me...
Lösung
As documented (always read the docs), printf()
returns:
...the length of the outputted string.
That's why you're getting 30.
If you're adding a value to an array or a string you need to use a function that returns a value. Not one that prints. printf()
prints the value and returns the length of the printed value. To return a formatted string, you need to use sprintf()
:
'label' => sprintf( __('Option to share on %s', 'theme-name'), 'name'),
See here for more on the difference between returning and printing/echoing.
