How to query the custom fields by language in wordpress? - 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.

How to get value from a field key (Ninja Forms)

Having a try with Ninja Forms, I’m actually able to get value from a field ID using $form_data array variable.
function my_ninja_function( $form_data ) {
$my_field_id = 1;
$my_value_from_field_id = $form_data['fields'][$my_field_id]['value'];
echo $my_value_from_field_id;
// output value is possible
}
And now trying to get value from a field key, without success...
$my_field_key = 'my_key';
$my_value_from_field_key = $form_data['fields'][$my_field_key]['value'];
echo $my_value_from_field_key;
// output value is not possible
with a little more effort...
$form_fields = $form_data['fields'];
foreach( $form_fields as $field ){
$field_value = $field['value'];
$field_key = $field['key'];
$data[$field_key] = $field_value;
};
$my_value_from_key = $data['my_key'];
echo $my_value_from_key;
// output is possible
It works!
By value I'm assuming you mean the field's label. You can get a field's label from the field's settings like this:
$form_id = 1;
$form_fields = Ninja_Forms()->form($form_id)->get_fields();
foreach( $form_fields as $field ) {
$model = $field->get_settings();
$label = $model['label'];
}
if you really do mean value, then perhaps you are referring to a form submission's field value. You can get those like this:
$sub_id = 1; // Need to know the submission's ID
$sub = Ninja_Forms()->form()->sub($sub_id)->get();
$form_id = 1;
$form_fields = Ninja_Forms()->form($form_id)->get_fields();
foreach( $form_fields as $field ) {
$model = $field->get_settings();
$value = $sub->get_field_value($model['key']); // User submitted value
}
Note that NinjaForms has added field keys in version 3 after I made the suggestion, as previous versions had no unique field identifier which made exporting/importing fields and forms very problematic.

Save geofield programmatically in Drupal 8

I have read in a lot of sources that I should use the geofield_compute_values() function when trying to programmatically save coordinates in Drupal.
However it does not work for me, that function is undefined in the Drupal 8.5.2 that I am using.
I've installed geofield using composer and I can use it as usual in the admin area and there are no problems with saving there.
Here are some examples I've tried with, the first example gives me undefined function geofield_compute_values() :
$geofield_data = geofield_compute_values([
'lat' => $lat,
'lon' => $lon,
], GEOFIELD_INPUT_LAT_LON);
$cbisProduct->set('field_koordinater', $geofield_data);
I have also tried this out with no successful result and no errors :
$geofield = [
'geom' => "POINT (" . $lon . " " . $lat . ")",
'geo_type' => 'point',
'lat' => $lat,
'lon' => $lon,
'left' => $lon,
'top' => $lat,
'right' => $lon,
'bottom' => $lat,
];
$cbisProduct->set('field_koordinater', $geofield);
Seems like you're trying to use the geofield_compute_values() function which was available in 7.x version, but not in 8.x
You should look into the wkt_generator service. i.e.
<?php $wktGenerator = \Drupal::service('geofield.wkt_generator'); ?>
I haven't tried this, but something like this should work:
<?php
$point = [
'lat' => $request->get('lat'),
'lon' => $request->get('lon'),
];
$value = \Drupal::service('geofield.wkt_generator')->WktBuildPoint($point);
$node->field_koordinater->setValue($value);
Also, WktGeneratorTest.php and GeofieldItemTest.php files could be a good start to see how to use the service in your implementation.
This function is not available in Drupal 8. You have to rely on the basic GeofieldItem class that extends FieldItemBase. Also, as mentioned by oman, you can use WktGenerator to easily build points, polygons, etc.
Here a working example. Let's say your have an entity $cbisProduct with a multivalued geofield field_koordinater, and you want to set the first item with arbitrary lat/lon coordinates :
// Get geofield item
$geofield = $cbisProduct->get('field_koordinater')->get(0);
// Generate a point [lat, lon]
$coord = ['45.909621', '6.127147'];
$point = \Drupal::service('geofield.wkt_generator')->WktBuildPoint($coord);
// Calling this function will compute values AND assign geodata to the field instance
$geofield->setValue($point);
// You can read the computed geodata from the field
$geodata = $geofield->getValue();
//dpm($geodata);
// Explicitly set field data (needed if $geofield is not a reference)
$cbisProduct->set('field_koordinater', [$geodata]);
// Save entity
$cbisProduct->save();
Under the hood, GeofieldItem::setValue calls another method responsible to directly assign the computed values to the field instance :
# \Drupal\geofield\Plugin\Field\FieldType\GeofieldItem
protected function populateComputedValues() {
/* #var \Geometry $geom */
$geom = \Drupal::service('geofield.geophp')->load($this->value);
if (!empty($geom)) {
/* #var \Point $centroid */
$centroid = $geom->getCentroid();
$bounding = $geom->getBBox();
$this->geo_type = $geom->geometryType();
$this->lon = $centroid->getX();
$this->lat = $centroid->getY();
$this->left = $bounding['minx'];
$this->top = $bounding['maxy'];
$this->right = $bounding['maxx'];
$this->bottom = $bounding['miny'];
$this->geohash = substr($geom->out('geohash'), 0, GEOFIELD_GEOHASH_LENGTH);
$this->latlon = $centroid->getY() . ',' . $centroid->getX();
}
}
Note : You don't necessarily need WktGenerator for building points, as long as you know the geofield type and how geophp should handle it. For example, the following 2 statements are equivalent :
$point = \Drupal::service('geofield.wkt_generator')->WktBuildPoint($coord);
// is equivalent to
$point = GEOFIELD_TYPE_POINT . '(' . implode(' ', $coord) . ')');
But it is safer to rely on the WktGenerator especially with more complex data types.

preg_replace to get part of url

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.

Display Label given key for select list

Given the following select list for the "field_priority" field, how can I display the label, given the key (e.g. 0, 1, 3)?
0|Low
1|Medium
2|High
3|Urgent
You can get it nice and quickly using field_info_field():
$key = 0; // Or whatever
$field = field_info_field('field_priority');
$label = $field['settings']['allowed_values'][$key];
There's a whole host of field functions in field.info.inc, they're very handy.
I would suggest to use list_allowed_values() instead of searching the array yourself:
$field = field_info_field('field_priority');
$options = list_allowed_values($field);
$label = $values[$key];
Or in short:
$label = list_allowed_values(field_info_field('field_priority'))[$key];

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.
