11:37amPippin Williamson says:It depends on how you've set up your custom column.
Here's an example I've used recently:
function announcement_edit_columns($announcement_columns){
$announcement_columns = array(
"cb" => "<input type=\"checkbox\" />",
"title" => "Title",
"topics" => "Topics",
"author" => "Author",
"date" => "Date",
"thumbnail" => "Thumbnail",
);
return $announcement_columns;
}
function announcement_columns_display($announcement_columns){
. . . . code for custom column display
}
add_filter("manage_edit-wp_announcements_columns", "announcement_edit_columns");
add_action("manage_posts_custom_column", "announcement_columns_display");
By simply changing the order of the items in $announcement_columns = array, you can change the order the columns are displayed.- 10/01/10 2:16pm
Pippin Williamson says:You need to include the other, default columns as well before you do
return $columns;
So your function should be:
function dt_add_post_columns($columns){
$columns['cb'] = '<input type="checkbox" />';
$columns['dt-post-thumbnail'] = __("Thumbnail");
$columns['title'] = __('Title');
$columns['author'] = __('Author');
$columns['categories'] = __('Category');
$columns['tags'] = __('Tags');
$columns['comments'] = __('Comments');
$columns['date'] = _x('Date', 'column name');
return $columns;
}

Utkarsh Kukreti says:Try
function dt_add_post_columns($columns){
$columns = array_merge( array( 'dt-post-thumbnail' => __("Thumbnail") ), $columns );
return $columns;

11:44amCosmin Popovici says:Damn, Pippin was fast :)
He's right, just place the "thumbnail" => "Thumbnail" before the "title" one and it'll work ;)
So here's the final code I'd use:
<?php
// Add custom columns to manage posts page
// Add to admin_init function
add_filter('manage_posts_columns', 'add_new_my_columns');
function add_new_my_columns($my_columns) {
$new_my_columns['cb'] = '<input type="checkbox" />';
$new_my_columns['thumbnail'] = __('Post Thumbnail');
$new_my_columns['title'] = __('Title');
$new_my_columns['author'] = __('Author');
$new_my_columns['categories'] = __('Category');
$new_my_columns['tags'] = __('Tags');
$new_my_columns['comments'] = __('Comments');
$new_my_columns['date'] = _x('Date', 'column name');
return $new_my_columns;
}
// Add to admin_init function
add_action('manage_posts_custom_column', 'manage_my_columns', 10, 2);

Joe Calithia says:This doesn't seem to be working for me. Here is my code...
<?php
add_filter("manage_posts_columns", "dt_add_post_columns");
add_action("manage_posts_custom_column", "dt_display_post_columns");
function dt_add_post_columns($columns){
$columns['my-post-thumbnail'] = __("Thumbnail");

Joe Calithia says:Sorry.. that code was messed up. Here is my working code.
<?php
add_filter("manage_posts_columns", "dt_add_post_columns");
add_action("manage_posts_custom_column", "dt_display_post_columns");
function dt_add_post_columns($columns){
$columns['dt-post-thumbnail'] = __("Thumbnail");
return $columns;
}
function dt_display_post_columns($column){
global $post;
switch($column):
case 'dt-post-thumbnail':
dt_image(false, 48, 48, 'dt-admin-thumb');
break;
endswitch;
}

Cosmin Popovici says:$columns['dt-post-thumbnail'] = __("Thumbnail");
That won't work, because WordPress doesn't know of dt-post-thumbnail.
Use just this:$columns['thumbnail'] = __("Thumbnail"); - 10/01/10 5:23pm
Joe Calithia says:Well this code...
<?php
add_filter("manage_posts_columns", "dt_add_post_columns");
add_action("manage_posts_custom_column", "dt_display_post_columns");
function dt_add_post_columns($columns){
$columns['dt-post-thumbnail'] = __("Thumbnail");
return $columns;
}
function dt_display_post_columns($column){
global $post;
switch($column):
case 'dt-post-thumbnail':
dt_image(false, 48, 48, 'dt-admin-thumb');
break;
endswitch;
}
...is working. See the original attached image. It sends it to the last column. How can I change it so that it shows up as the first column?

add_filter("manage_posts_columns", "my_column",10,2);
add_action("manage_posts_custom_column", "my_column",10,2);
Where you can change the value of 2 to adjust the position of column. Not tested though. -

9:03pmDenzel Chia says:Hi Joe,
Based on your working codes, simply unset $column and reconstruct the array before returning.
Use the following codes, I had tested in my localhost.
<?php
add_filter("manage_posts_columns", "dt_add_post_columns");
add_action("manage_posts_custom_column", "dt_display_post_columns");
function dt_add_post_columns($columns){
unset($columns);
$columns = array(
'cb' => '<input type="checkbox"/>',
'dt-post-thumbnail' => __("Thumbnail"),
'title' => __('Title'),
'author' => __('Author'),
'categories' => __('Category'),
'tags' => __('Tags'),
'comments' => '<img src="images/comment-grey-bubble.png" alt="Comments">',
'date' => _x('Date', 'column name'),
);
return $columns;
}
function dt_display_post_columns($column){
global $post;
switch($column):
case 'dt-post-thumbnail':
dt_image(false, 48, 48, 'dt-admin-thumb');
break;
endswitch;
}

Denzel Chia says:Added the attachment screen shot as proof.
Notice the position of the thumbnail column, is second to check boxes.
"There are no images" in my example because I do not know what dt_image() function is.
Butthis code will definitely work for you!
Thanks for the learning opportunity!
