Hi all,
I have created a new theme on my own server and now i've uploaded it to the server where it use to be, and I get this massage:
Warning: Cannot modify header information - headers already sent by (output started at /home2/missfas1/public_html/wp-content/themes/missfashionnews/functions.php:47) in /home2/missfas1/public_html/wp-includes/pluggable.php on line 897
The servers running all on version 3.13.
Does somebody know how I can fix this?
Thanks,
Jason

output started at /home2/missfas1/public_html/wp-content/themes/missfashionnews/functions.php:47
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 $post;
return '... <a href="'. get_permalink($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:
?>
<?phpAnd 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.

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?
Posted 11 months ago #
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 $post;
return '... <a href="'. get_permalink($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.

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!!!

I'm not really sure what you mean?
Posted 11 months ago #
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.
