preg_replace to get part of url - http

i currenting use ereg_replace
$myurl="http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$theid= ereg_replace("[^0-9]", "", $myurl);
To get an id at the end of the url entered
Id like to use preg_replace and accomplish getting two types of ids
one looking like http:// site.com?id=64
like I do above
but I want to also get one that would contain http:// site.com?pick=7878787
I am trying to assign pick id's to one variable called $thepickupcode
and the other to a variable called $theid
Any help I am happy about.

A non regex way:
$res = parse_url($myurl);
parse_str($res['query'], $query);
$theid = $query['id'];
$thepickupcode = $query['pick'];
A regex way:
if (preg_match('~(?<=[?&])(id|pick)=([0-9]++)(?=&|$)~', $_SERVER['REQUEST_URI'], $match))
if ($match[1] == 'id') $theid = $match[2];
else $thepickupcode = $match[2];

Your question is not clear, but I think you want something like:
Then you want preg_match, not replace.
preg_match( '~(pick|id)=(.+)~i', $myurl, $res );
print_r( $res );
I am not sure what all the possibilities are, but this may be more appropriate:
preg_match( '~\?(pick|id)=([0-9]+)$~i', $myurl, $res );
print_r( $res );

When you want to change ereg... to preg..., you have to enclose the regex in delimiters.
For your example:
$theid= ereg_replace("[^0-9]", "", $myurl);
becomes:
$theid = preg_replace("/[^0-9]/", "", $myurl);
or
$theid = preg_replace("/\D+/", "", $myurl);
But this will give you wrong result if there are other numbers than the id.
I suggest you follow #CasimiretHippolyte 's answer.

automatically generate tags from content in wordpress

my WordPress website contents have some words in every line,
I want a code to automatically convert every line in content to tag (every line not every word), let's say my content is like this:
Beagle puppy
Costumes
Wales
Dogs
I want tags from every line: Beagle puppy, Costumes, Wales, Dogs
I don't want to use plugins, because I used some but it needs a keyword list to match the content. I don't want to use any keyword list to match the content.
is it possible to convert every line in content into one tag?
Assuming you meant what you appeared to mean - for instance, that the source post consists solely of the lines to be converted, the lines won't include additional odd/inappropriate chracters to be handled, and so on - the following will work. If you need to convert a section of a post or some other element defined in some other way, or attach the lines as tags to the current post, etc., then you'll need to provide those details clearly.
Place shortcode [convert_post_lines_to_tags] in new output post.
Save draft, and preview (shortcode won't function yet, obviously)
Add functions to your theme functions.php
Provide "$source_post_id" where indicated.
Re-load output post
add_shortcode( 'convert_post_lines_to_tags', 'convert_post_lines_to_tags' ) ;
function convert_post_lines_to_tags() {
$source_post_id = '' ; //Provide ID Number of post with lines to be converted
$i = 0 ;
$newTags = 'New tags inserted: <br />' ;
//TIL - PHP requires double quotes to replace escaped characters
$post_content = str_replace(
array( "\r\n", "\r" ), ',', get_post( $source_post_id )->post_content
) ;
$post_line_array = explode( ',', $post_content ) ;
foreach ( $post_line_array as $line_tag ) {
$tag = wp_insert_term( $line_tag, 'post_tag' ) ;
if ( ! is_wp_error( $tag ) ) {
$i++ ;
$newTags .= $i . '. ' . get_term( $tag['term_id'] )->name . '<br />' ;
}
}
return $newTags ;
}

How to query the custom fields by language in wordpress?

For each post, there is a custom field name "Function", the key/value pair is like this:
Key : Functions
Value : <!--en-->Nourishing Yin and invigorating the vital essence of kidneys.<!--:--><!--tw-->滋陰補腎。<!--:-->
The problem is if I simply use get_post_meta , it return string of both language, how can I get the value based on the language?
I am using qTranslate right now, Thanks.
Updated (the code):
$custom_fields = get_post_custom(get_the_ID());
$function = get_post_custom_values('Functions', get_the_ID());
You can simply fetch the strings considering comments as prefix and suffix -
After you get the custom field value,
e.g.
$function = "<!--en-->Nourishing Yin and invigorating the vital essence of kidneys.<!--:--><!--tw-->滋陰補腎。<!--:-->";
$arr = explode("<!--:-->", $function);
$new_arr = array();
foreach($arr as $a ){
if(!empty($a)){
$lang = str_replace( "-->", "", substr($a, 4, 5) );
$str = substr($a, 9);
$new_arr[$lang] = $str;
}
}
Now $new_arr will have key/value pairs like array(language_code => sentence).
If you do print_r($new_arr);
It will give output as follows:
Array ( [en] => Nourishing Yin and invigorating the vital essence of kidneys. [tw] => 滋陰補腎。 )
Now you can identify the strings using their respective language codes.

Rename files during upload within Wordpress

I am trying to rename upload filenames match the Post Title.
This other thread shows how to rename to hash:
Rename files during upload within Wordpress backend
Using this code:
function make_filename_hash($filename) {
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
$name = basename($filename, $ext);
return md5($name) . $ext;
}
add_filter('sanitize_file_name', 'make_filename_hash', 10);
Does anyone know the code to rename the file to match Post Title.extension?
barakadam's answer is almost correct, just a little correction based on the comment I left below his answer.
function new_filename($filename, $filename_raw) {
global $post;
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
$new = $post->post_title . $ext;
// the if is to make sure the script goes into an indefinate loop
if( $new != $filename_raw ) {
$new = sanitize_file_name( $new );
}
return $new;
}
add_filter('sanitize_file_name', 'new_filename', 10, 2);
Explanation of code:
Lets assume you upload a file with the original filename called picture one.jpg to a post called "My Holiday in Paris/London".
When you upload a file, WordPress removes special characters from the original filename using the sanitize_file_name() function.
Right at the bottom of the function is where the filter is.
// line 854 of wp-includes/formatting.php
return apply_filters('sanitize_file_name', $filename, $filename_raw);
At this point, $filename would be picture-one.jpg. Because we used add_filter(), our new_filename() function will be called with $filename as picture-one.jpg and $filename_raw as picture one.jpg.
Our new_filename() function then replaces the filename with the post title with the original extension appended. If we stop here, the new filename $new would end up being My Holiday in Paris/London.jpg which all of us know is an invalid filename.
Here is when we call the sanitize_file_name function again. Note the conditional statement there. Since $new != $filename_raw at this point, it tries to sanitize the filename again.
sanitize_file_name() will be called and at the end of the function, $filename would be My-Holiday-in-Paris-London.jpg while $filename_raw would still be My Holiday in Paris/London.jpg. Because of the apply_filters(), our new_filename() function runs again. But this time, because $new == $filename_raw, thats where it ends.
And My-Holiday-in-Paris-London.jpg is finally returned.
Something like this? (considering $post is your post variable, make it global):
function new_filename($filename) {
global $post;
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
return $post->post_title . $ext;
}
add_filter('sanitize_file_name', 'new_filename', 10);

Wordpress - Excerpt character alternative?

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....

Drupal module_invoke() and i18n

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.
