I am tasked with i18n-ing our current CMS setup in Drupal.
The problem that I am facing is with use of module_invoke() to place blocks within nodes.
I have managed to string translate blocks, and that is working when a block is placed in a region (block content is successfully translated) using the UI.
However, when a block is injected into a node like such:
$block = module_invoke('block', 'block', 'view', 22); print $block['content'];
It is not getting translated, or even worse, not showing at all.
I have also tried this variation using t(). e.g.:
$block = module_invoke('block', 'block', 'view', 22); print t($block['content']);
to no avail.
Generally speaking I've having a bit of trouble with blocks for i18n. Does anyone have a recommended approach for dealing with blocks in drupal with regards to translating them? I would prefer not to create different blocks for each language.
So .. After digging around in the bowels of Drupal - and much hair pulling .. I've come up with an almost decent solution.
Basically, with this function, I can extract a translated version of a block:
function render_i18n_block($block_id, $region = "hidden"){
if ($list = block_list($region)) {
foreach ($list as $key => $block) {
// $key == <i>module</i>_<i>delta</i>
$key_str = "block_".$block_id;
if ($key_str == $key){
return theme('block', $block);
}
}
}
}
Then, in my node, I simple call:
<?php echo render_i18n_block(<block_id>,<region>); ?>
There can be some issues where your blocks might not be displaying in a region (and therefore you can't pass a region into block_list). For this case, I simply created a region called "hidden" which is not rendered anywhere in my template, but can be used to call block_list.
Finally (and this is the part that I still need to find a good solution for), I discovered that block_list() in: includes/blocks/block.inc has a bit of an issue.
It appears that $theme_key is not reliably set unless block_list() is being called from the theme() function (in includes/themes.inc) .. this causes the SQL to return an empty results set. The SQL looks like this:
$result = db_query(db_rewrite_sql("SELECT DISTINCT b.* FROM {blocks} b LEFT JOIN {blocks_roles} r ON b.module = r.module AND b.delta = r.delta WHERE b.theme = '%s' AND b.status = 1 AND (r.rid IN (". db_placeholders($rids) .") OR r.rid IS NULL) ORDER BY b.region, b.weight, b.module", 'b', 'bid'), array_merge(array($theme_key), $rids));
As you can see, if theme_key is not set, then it will just return an empty result.
For now I am bypassing this by simply adding:
if (!isset($theme_key)){$theme_key="<my_theme_name>";}
in modules/blocks/block.inc::block_list() around line 429 .. I still need to work out a better way to do this.
10 for anyone with suggestions on how I could ensure that $theme_key is set before calling block_list :)
I had exactly the same problem as you, since I was using
$block = module_invoke('block', 'block_view', 'block_id');
print render($block['content']);
to inject the block into my nodes. However, looking up module_invoke in the Drupal reference, I found a comment titled "to render blocks in Drupal 7 better to use Block API", with this code:
function block_render($module, $block_id) {
$block = block_load($module, $block_id);
$block_content = _block_render_blocks(array($block));
$build = _block_get_renderable_array($block_content);
$block_rendered = drupal_render($build);
return $block_rendered;
}
I just un-functioned it to use directly, like so:
$block = block_load('block', 'block_id');
$block_content = _block_render_blocks(array($block));
$build = _block_get_renderable_array($block_content);
print render($build);
And for me it works like a charm. Be aware however that this method prints the block title as well, so maybe you'll want to set it to 'none' in the original language.
Create a function like this
<?php
function stg_allcontent2($allC, $level
= "1") {
global $language; $lang = $language->language;
foreach ($allC as $acKey => $ac) {
if($ac['link']['options']['langcode']
== $lang){ if ($level == "1")
$toR .= "";
if (is_array($ac['below']))
$class="expanded"; else
$class="leaf";
$toR .= "<li class=\"".$class."\">" . l($ac['link']['link_title'], $ac['link']['link_path']) . "</li>";
if ($level != "1") $toR .= ""; if (is_array($ac['below'])) $toR .= "<ul class=\"menu\">".stg_allcontent2($ac['below'], "2")."</ul>"; if ($level == "1") $toR .= ""; }
}
return $toR; } ?>
call like this
<?php echo '<ul class="menu">'; echo stg_allcontent2(menu_tree_all_data($menu_name
= 'menu-header', $item = NULL)); echo '</ul>'; ?>

UPDATE: the t() function allows you to pass in the language code to use.

at the moment I'm developing a plugin, which hooks up to the content editor. My callback receives the post content after editing and calls do_shortcode(), but there is a problem and i don't know how to fix it.
add_filter('wp_insert_post_data', 'prepareContentSaving', 99, 2);
add_filter('wp_update_post_data', 'prepareContentSaving', 99, 2);
For instance if my post looks like (which obviously looks like valid shortcode syntax):
[foo bar="two words"]
my callback receives:
[foo bar=\"two words\"]
Looks right, right? But now whenever the shortcode is parsed via do_shortcode() the arguments are parsed like
[tag argument1=value1 argument2]
instead of
[tag argument="Foo bar"]
which then looks something like this in PHP:
array(
[0]=> string "bar=\"two"
[1]=> string "words\""
)
So how can I prevent the quotes inside the shortcode from being escaped? Is there something wrong with the post data hook? Changing the priority from 99 to 0 doesn't change something either. Am I using the right filter?
You can try to modify your code like this:
$post = array_map('stripslashes_deep', $_POST);
More info link: http://codex.wordpress.org/Function_Reference/stripslashes_deep
WordPress actually doesn't feature any option for preventing shortcodes to be escaped. The only way is to undo it is to convert all '\"' back to '"' (same for single quotes) inside the function 'prepareContentSaving':
add_filter('wp_insert_post_data', 'prepareContentSaving', 99, 2);
add_filter('wp_update_post_data', 'prepareContentSaving', 99, 2);
function prepareContentSaving($data, $post) {
$content = $post['post_content'];
$content = correctShortcodeSlashes($content);
... any further processing ...
$data['post_content'] = $content;
return $data;
}
After saving a post wordpress not only escapes quotes but also escapes backslashes. So '"' becomes '\"' and '\"' (if the editor wants to escape a quote) becomes '\\"'.
The first given PCRE converts all single escaped quotes inside shortcode brackets back to normal quotes, the second one converts all the double escaped ones inside brackets. This way the content stays the same which reduces the chances of code injection.
PHP Manual on preg_replace
function correct_shortcode_slashes($text) {
$attribute_escaped_slashes_pattern = '/(\[)((.|\s)*?)([^\\\\])\\\\("|\')(.*?)(\])/';
$attribute_escaped_slashes_replacement = '$1$2$4"$6$7';
$attribute_double_slashes_pattern = '/(\[)((.|\s)*?)\\\\+("|\')(.*?)(\])/';
$attribute_double_slashes_replacement = '$1$2"$5$6';
$result = $text;
$counter = 0;
while(true) {
$result = preg_replace($attribute_escaped_slashes_pattern, $attribute_escaped_slashes_replacement, $result, -1, $counter);
if($counter === 0) {
break;
}
}
while(true) {
$result = preg_replace($attribute_double_slashes_pattern, $attribute_double_slashes_replacement, $result, -1, $counter);
if($counter === 0) {
break;
}
}
return $result;
}

Current I have WP code like this. I need to make it translateable by poedit. How do I wrap the code to make it work? Im not sure which method is use for this case. Some thing like:
<?php my_e( 'Total sales' ); ?> or __('Total sales', 'my')
This is the code. I need to translate ["Sales amount"], ["Number of sales"]
foreach ($results as $result) {
$date = $result->formatted_post_date;
$statistics[$date]["Sales amount"] += $wp_list_table->column_total_sales($result->ID);
$statistics[$date]["Number of sales"]++;
$statistics[$date]["date"] = $date;
$max_number_of_sales = max(array($max_number_of_sales,$statistics[$date]["Number of sales"] )); }
Thank you for help
You have to use __('string','textdomain') to assign a translated string to some variable. And _e('string','textdomain') to echo a translated string. See I18n_for_WordPress_Developers.
Two observations:
you'll not be able to translate array keys, see php.net/manual/en/language.types.array.php
what you're doing seems wrong. I'd do it like:
$sales_amount = 0;
$sales_number = 0;
foreach ($results as $result) {
$sales_amount += $wp_list_table->column_total_sales($result->ID);
$sales_number++;
$date = $result->formatted_post_date;
$statistics[$date]["sales_amount"] = $sales_amount;
$statistics[$date]["sales_number"] = $sales_number;
}
echo __( 'Sales Amount', 'my' ) . $sales_amount;
Pretty much as per the question, how would I go about creating a view that only showed content older than the current node's created date?
I've created the argument using 'Content: created date' but struggling to pass this over to the filter criteria.
To be honest, I'm not even sure this is the correct way to do it!
Managed to get this working with a Views PHP field:
<?php
global $base_path;
if (arg(0) == 'node' && is_numeric(arg(1)) && ! arg(2)) {
$node = node_load(arg(1));
$a1 = format_date($node->created, 'custom', 'm/d/Y');
$a2 = date("m/d/Y",strtotime("-2 months",strtotime($a1)));
$a3 = format_date($row->created, 'custom', 'm/d/Y');
$b1 = new DateTime($a1);
$b2 = new DateTime($a2);
$b3 = new DateTime($a3);
if ($b3 >= $b2 && $b3 <= $b1) {
print '<h2>' . $row->title . '</h2>' . $data->field_body[0]['rendered']['#markup'];
//dsm($data);
}
}
?>
I'm trying to search for a way to order categories by meta value. From what I read, it seems like I can use:
get_categories('child_of=92&hide_empty=false&orderby=meta_value&meta_key=date&order=ASC');
However, this does not work at all, the categories are still not in the order I want. I wonder how I can:
correct this to make it work
print out the sql to see what is really going on inside?
Thank you very much in advance.
First of all, I must mention that I'm using the module custom category fields, and second of all I'm a complete WP newbie
Anyhow, after learning that this cannot be done by default, I looked into the get_categories functions and finally came up with a solution
function category_custom_field_get_terms_orderby( $orderby, $args ){
if($args['orderby'] == 'category_custom_field' && isset($args['category_custom_field']))
return 'cv.field_value';
return $orderby;
}
function category_custom_field_get_terms_fields( $selects, $args ){
if($args['orderby'] == 'category_custom_field' && isset($args['category_custom_field']))
$selects[] = 'cv.*';
return $selects;
}
function category_custom_field_terms_clauses($pieces, $taxonomies, $args){
global $wpdb;
if($args['orderby'] == 'category_custom_field' && isset($args['category_custom_field']))
$pieces['join'] .= " LEFT JOIN $wpdb->prefix" . "ccf_Value cv ON cv.term_id = tt.term_id AND cv.field_name = '".$args['category_custom_field']."'";
return $pieces;
}
add_filter('get_terms_orderby', 'category_custom_field_get_terms_orderby',1,2);
add_filter('get_terms_fields', 'category_custom_field_get_terms_fields',1,2);
add_filter('terms_clauses', 'category_custom_field_terms_clauses',1,3);
(The code above can be put into the theme functions.php file)
then the code to get categories is:
get_categories('child_of=92&hide_empty=false&orderby=category_custom_field&category_custom_field=date&order=DESC');
Any correction is greatly appreciated!
You can also give the get_categories new meta and sort using usort.
$subcategories = get_categories();
foreach ($subcategories as $subcategory) {
$subcategory->your_meta_key = your_meta_value;
}
foreach ($subcategories as $subcategory) {
blah blah blah
}
function my_cmp($a, $b) {
if ($a->ordering == $b->ordering) {
return 0;
}
return ($a->ordering < $b->ordering) ? -1 : 1;
}
usort($subcategories, "my_cmp");
I'm totally new to WordPress so be easy :)
I the following code in a template:
<?php excerpt(20);?>
What this does is limit the text with 20 words. I am now wondering if there is some sort of similar function that limits by characters instead of words?
Thanks!
I use this:
add_filter('excerpt_length', 'my_excerpt_length');
function my_excerpt_length($length) {
return '500';
}
function better_excerpt($limit, $id = '') {
global $post;
if($id == '') $id = $post->ID;
else $id = $id;
$postinfo = get_post($id);
if($postinfo->post_excerpt != '')
$post_excerpt = $postinfo->post_excerpt;
else
$post_excerpt = $postinfo->post_content;
$myexcerpt = explode(' ', $post_excerpt, $limit);
if (count($myexcerpt) >= $limit) {
array_pop($myexcerpt);
$myexcerpt = implode(' ',$myexcerpt).'...';
} else {
$myexcerpt = implode(' ',$myexcerpt);
}
$myexcerpt = preg_replace('`\[[^\]]*\]`','',$myexcerpt);
$stripimages = preg_replace('/<img[^>]+\>/i', '', $myexcerpt);
return $stripimages;
}
And then in my theme file, I just call it in with:
better_excerpt('50') //50 being how many words I want
Useful for custom plugins/widgets too.
Wordpress doesn't support the character delimiter for the excerpt method, there's a plugin called Advanced Excerpt that does. After installing you can call the_advanced_excerpt('length=20&use_words=0')
I use this in my functions.php:
function truncate ($str, $length=10, $trailing='...'){
// take off chars for the trailing
$length-=mb_strlen($trailing);
if (mb_strlen($str)> $length){
// string exceeded length, truncate and add trailing dots
$str = mb_substr($str,0,$length);
$str = explode('. ',$str);
for( $i=0; $i<(sizeof($str)-2); $i++ ):
$newstr .= $str[$i].". ";
endfor;
return $newstr;
} else{
// string was already short enough, return the string
$res = $str;
}
return $res;
}
It should truncate to a character count, but then truncate back further to the last period before the truncation. It does get problematic when your excerpt includes links, however, or other markup - in other words, it's best to use the Excerpt field in the post rather than auto-excerpting with this function, because you can't use HTML in the excerpt field.
Please use this code for limiting post content...
<?php substr($post->post_content, 0, xy); ?> ...
Change the limit of XY....
