What is the code on line 47 of functions.php?

This error is usually caused by something being output rather than returned in functions.php.

This is the whole function.php file. I don’t see something wrong in it and this theme works on my own server correctly.

<?php

if (function_exists('register_sidebar'))
{
    register_sidebar(array(
        'before_widget' => '<li id="%1$s" class="widget %2$s">',
        'after_widget' => '</li>',
        'before_title' => '<h2 class="widgettitle">',
        'after_title' => '</h2>',
    ));
}

?>
<?php
function new_excerpt_length($length) {
	return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');
?>
<?php
function new_excerpt_more($more) {
       global $post;
	return '... &nbsp;<a href="'. get_permalink($post->ID) . '">Read more.</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');
?>
<?php
if (class_exists('MultiPostThumbnails')) {
    $types = array('post', 'page', 'my_post_type');
    foreach($types as $type) {
        $thumb = new MultiPostThumbnails(array(
            'label' => 'Secondary Image',
            'id' => 'secondary-image',
            'post_type' => $type
            )
        );
    }
}
?>
<?php
set_post_thumbnail_size( 250, 250, true ); // default post thumbnail size with a hard crop
// use "false" for soft crop, or box resize mode
?>
<?php
function register_my_menus() {
  register_nav_menus(
    array('header-menu' => __( 'Header Menu' ) )
  );
}
?>
<?php
add_action( 'init', 'register_my_menus' );
?>

Thank for your quick help!

Ouch… first, if you need to post blocks of code longer than about 10 lines, please use Pastebin, and put a link in your post.

Second, as there is no line-numbering, it is difficult to tell which is line 47.

If I had to guess, the problem lies in your repetitive closing/opening of PHP tags. In functions.php, you should never close PHP tags, unless you need to do so (e.g. to define HTML output inside of a function).

Everywhere in your file, remove the following wherever they appear:

?>
<?php

And if that doesn’t solve the problem:

1. Make sure you have no whitespace whatsoever at the end of the file
2. Try removing the final, closing PHP tag; it is actually unnecessary.

Thanks!!

It helps a lot but I have a new message:

Fatal error: Call to undefined function has_post_thumbnail() in /home2/missfas1/public_html/wp-content/themes/missfashionnews/index.php on line 25

Fatal error: Call to undefined function has_post_thumbnail()

What version of WordPress are you using? has_post_thumbnail() is a core WordPress function, introduced in version 2.9.

I use version 3.13. Do I need a different code format?

I don’t think it will matter (the function should be defined regardless), but do you have the following in functions.php?

add_theme_support( 'post-thumbnails' );

No, I don’t have it. Where do I set this code. My function.php looks like this:

<?php

if (function_exists('register_sidebar'))
{
    register_sidebar(array(
        'before_widget' => '<li id="%1$s" class="widget %2$s">',
        'after_widget' => '</li>',
        'before_title' => '<h2 class="widgettitle">',
        'after_title' => '</h2>',
    ));
}
function new_excerpt_length($length) {
	return 100;
}
add_filter('excerpt_length', 'new_excerpt_length');

function new_excerpt_more($more) {
       global $post;
	return '... &nbsp;<a href="'. get_permalink($post->ID) . '">Read more.</a>';
}
add_filter('excerpt_more', 'new_excerpt_more');
if (class_exists('MultiPostThumbnails')) {
    $types = array('post', 'page', 'my_post_type');
    foreach($types as $type) {
        $thumb = new MultiPostThumbnails(array(
            'label' => 'Secondary Image',
            'id' => 'secondary-image',
            'post_type' => $type
            )
        );
    }
}
set_post_thumbnail_size( 250, 250, true ); // default post thumbnail size with a hard crop
// use "false" for soft crop, or box resize mode

function register_my_menus() {
  register_nav_menus(
    array('header-menu' => __( 'Header Menu' ) )
  );
}
add_action( 'init', 'register_my_menus' );

I really appreciate it.

Jason

You can put it anywhere inside of functions.php. Semantically, you might want to put it before your other thumbnail-related functions, such as set_post_thumbnail_size().

p.s. please remember the ten-lines-of-code rule.

Can you set multiple functions on one line?

But the problem is solved!!

Thanks a lot!!!

Jason

Can you set multiple functions on one line?

I’m not really sure what you mean?

I mean the ten-line-of-code rule. Can you compress the code to ten lines with multiple functions on one line?

hi chip bennett

i have just now posted my problem

I mean the ten-line-of-code rule. Can you compress the code to ten lines with multiple functions on one line?

I suppose you could, but it would make the code unreadable.

Using pastebin is easy, and strongly recommended for lengthy code blocks.

Thanks!

You helped me a lot!!
