Creating new po files with a po editor

Question

I tried some po editor softwares. I wonder why none of do not allow creating a new po file from scratch or adding new entry to an existed one. Is there any hack so they let creating new entries? (I know that po files are plain text and can be edited in any text editor!)

Answer 1

PO editors are for translating a PO file from one language to another. They aren't designed to create PO files. Your PO files should be created as part of a build system not by an editor.

If you want to create them for testing then they are pretty easy to create either by using another existing PO files or by uncompiling an MO file (using msgunfmt).

Answer 2

Script auto create .po file, auto add all text from you code

1. Add load_theme_textdomain('my-textdomain',DIR.'/languages/');
2. Create folder wp-content/themes/MY_THEME/languages (add your language .mo file to this folder)
3. Create po.php and add this script:

<?php /*Script by Sien.com.vn */
define('WP_USE_THEMES', true);

require(''.$_SERVER['DOCUMENT_ROOT'].'/wp-load.php' );


function title_p($title) {

$title='Po create';   

return $title;}
add_filter( 'pre_get_document_title', 'title_p' );


$robots_p='noindex,nofollow';   

get_header();  


echo '<div id="content" class="col col-100">';


if(current_user_can('manage_options')){

function write_txt($path,$content,$type){
$file=fopen($path,$type) or die();
fwrite($file,$content);
fclose($file);
return TRUE;
}



if(isset($_POST['lang'])){
$lang_code=pathinfo($_POST['lang'],PATHINFO_FILENAME);

load_textdomain('this_lang',__DIR__.'/'.$lang_code.'.mo');


$textdomain=$_POST['textdomain'];


$txt='';

function sfile($dir, $ext) {
	global $textdomain;



$globFiles = glob("$dir".DIRECTORY_SEPARATOR."*.$ext");
$globDirs = glob("$dir/*", GLOB_ONLYDIR);

foreach ($globDirs as $dir) {
sfile($dir, $ext);

}

foreach ($globFiles as $file=>$path) {



$txt.=file_get_contents($path,FILE_USE_INCLUDE_PATH);



}


preg_match_all('/(translate|__|_e|esc_attr__|esc_attr_e|esc_html__|esc_html_e) ?\( ?(\'|\")(.+?)(\'|\") ?, ?(\'|\")'.$textdomain.'(\'|\") ?\)/',$txt,$output);



foreach(array_unique($output[3]) as $v){

	if(isset($v)){
	
write_txt(''.__DIR__.'/po.dat',''.(str_replace(array("\'",'\"'),array("'",'"'),$v)).'**$!3|\\/**','a+');
	}
}


}
sfile(get_template_directory(),'php');



$get=file_get_contents(''.__DIR__.'/po.dat');

$k=explode('**$!3|\\/**',$get);


foreach(array_unique($k) as $v){
	
	if(!empty($v)){ 
	
if($v==__($v,'this_lang')){
write_txt(''.__DIR__.'/po.dat.empty','
msgid "'.$v.'"
msgstr ""

}else{
write_txt(''.__DIR__.'/po.dat.isset','

	}
	
if(empty(file_get_contents(''.__DIR__.'/po.dat.isset')) && empty(file_get_contents(''.__DIR__.'/po.dat.empty'))){
		echo '<div class="error">Error, Textdomain <b>'.$textdomain.'</b> not found!</div>';

4. Go to youdomain/wp-content/themes/MY_THEME/languages/po.php and create .po file
5. Copy wp-content/themes/MY_THEME/languages/[LANG].po to desktop and open with Poedit -> Compile MO -> copy [LANG].mo to languages folder
