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];

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.
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.
I have five custom fields for loading images but all of them are not required. I mean the user can upload a random number of images from 1 to 5. I am stuck in a simple lack of concept here. How should I check if any of them is empty and discard it. More specifically I want to discard the non-existing fields and store only the uploaded ones in an array. Here is my code
$custom_fields = get_post_custom($id);
$my_custom_field1 = $custom_fields['image1'];
$my_custom_field2 = $custom_fields['image2'];
$my_custom_field3 = $custom_fields['image3'];
$my_custom_field4 = $custom_fields['image4'];
$my_custom_field5 = $custom_fields['image5'];
if(!(false===($my_custom_field1))) { $img[]=$my_custom_field1;}
if(!(false===($my_custom_field2))) { $img[]=$my_custom_field2;}
if(!(false===($my_custom_field3))) { $img[]=$my_custom_field3;}
if(!(false===($my_custom_field4))) { $img[]=$my_custom_field4;}
if(!(false===($my_custom_field5))) { $img[]=$my_custom_field5;}
$images = Array("image1","image2","image3","image4","image5");
foreach($images as $image){
if(isset($custom_fields[$image])){
$img[] = $custom_fields[$image];
}
}
Didn't tested that, but should work.
if(isset($my_custom_field5)){
// do something with $my_custom_field5
}
I would suggest using
if ( !empty($my_custom_field)){
\\Do Something
}
because isset only checks for variable beings set and not null where as empty checks if the variable is an empty string, false, array(), NULL, “0?, 0, and an unset variable.
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' ) . $sales_amount;
How to get list of terms of a node ( by node id) belongs to a particular vocabulary. Is there any drupal function ?
taxonomy_node_get_terms function.
http://api.drupal.org/api/function/taxonomy_node_get_terms/6
Or also:
taxonomy_node_get_terms_by_vocabulary
http://api.drupal.org/api/function/taxonomy_node_get_terms_by_vocabulary/6
I know there is api for getting list of vocabularies But i am nto sure, one api exist for gettign list of terms of vocabularies.
However, you can try this function. It will work.
function myutils_get_terms_by_vocabulary($vname, $tname = "") {
$sql = "select td.*
from term_data td
inner join vocabulary v on td.vid = v.vid
where v.name = '%s'";
if($tname) {
$result = db_query($sql . " and td.name = '%s'", $vname, $tname);
return db_fetch_object($result);
} else {
$result = db_query($sql, $vname);
}
$terms = array();
while ($term = db_fetch_object($result)) {
$terms[$term->tid] = strtolower($term->name);
}
return $terms;
}
Basically i created a 'myutils' module for such common functions and added this function there. so that i can use them in all similar scenarios.
