I found that I had to manipulate my CI language files from forms when managing database content. My situation was that I had a database of listings which were grouped into categories. My site was obviously multilingual and I wanted the titles of the categories to be dictated by language files so all the language items were in the same place.
With this extension, you can easily find which languages are installed in your application. Optionally, you can specify to look in the system/language folder instead if you are using languages that are shared by multiple applications. You can also look for languages in other applications by adding FCPATH.'/myapplication/language to the parameters when calling the find method.
Example
Code:
//This code finds languages in the language path of the current application
$existing_languages = $this->lang->find();
foreach($existing_languages as $lang){
$options[$lang] = ucfirst($lang);
}
echo form_dropdown('languages', $options);
You can add lines to either a specific language(english, german, etc) or in all languages(not sure why you would want to do this, but hey, why not?) See below.
Code:
$existing_languages = $this->lang->find();
foreach($existing_languages as $lang){
echo '<input type="text" name="'.$lang.'_title.'">
}
foreach($existing_languages as $lang){
$this->lang->add_line('cat_'.$this->db->insert_id(), $this->input->post($lang.'_title'), 'category_names', $lang);
}
Changing existing lines is just as easy.
Code:
$existing_languages = $this->lang->find();
foreach($existing_languages as $lang){
$this->lang->change_line('cat_'.$cat_id, $this->input->post($lang.'_title'), 'category_names', $lang);
}
Deleting lines... Probably the only time you'll want to make the same changes to all languages.
Code:
$existing_languages = $this->lang->find();
foreach($existing_languages as $lang){
$this->lang->delete_line('cat_'.$cat_id, 'category_names');
}
When you make changes to a language file and don't specify a language path(e.g. myapplication/language), it will first look in the language folder of the current application. If no file is found, it will then check the system/language folder for your file.
I still use CI 2.2.6, so this hasn't been tested in CI 3 or anything else. I'm not sure how different(if at all) the language class is in versions >= 3.
Make sure all files inside your language directory are writable.
Copy and paste this code into a file named "My_Lang.php" and save it to your application's core directory(e.g. application/core)
Enjoy! Ask if you have any questions.
