Hi,

I have written a module to browse images. I use a div data-option attribute to pass parameters from the backend to the javascritpt. These options includes translated texts for a frontend user menu.
Here is how the template is written

<div id="param" data-options =' $getParams'></div>

in the controller the getParams function is like this:

 function getParams(){
  return  (	'{"nbThumbPerRow": "'.$this->nbThumbsPerRow.'", '.
		'"nbThumbRows": "'.$this->nbRows.'", '.
		'"pauseTime": "'.$this->totalTime.'", '.
		'"transTime": "'.$this->transTime.'", '.
		'"menuTextCollapsed" : "'. _t("ImageBrowserPage.MENUTEXTCOLLAPSED").'", '.
		'"menuTextExpanded" : "'. _t("ImageBrowserPage.MENUTEXTEXPANDED").'", '.
		'"panelToggleText" : "'. _t("ImageBrowserPage.PANELTOGGLETEXT").'", '.
		'"menuSettingText1" : "'. _t("ImageBrowserPage.MENUSETTINGTEXT1").'" ,'.
		'"menuSettingText2" : "'. _t("ImageBrowserPage.MENUSETTINGTEXT2").'"}' );
}

All seems to work correctly. My only trouble is when a translated text (for example ImageBrowserPage.MENUSETTINGTEXT1) includes some special characters that are normal characters of the translated language as <'> which is common in French . This seems to break the template. I have tried to use addslashes before _t("ImageBrowserPage.MENUSETTINGTEXT1") but it doesn't change anything as \' appears as it is in the string.

How should I proceed to make the program insensitive to the introduction by a translator of such a char?

I recommend to use json_encode() to parse your JSON string and let PHP handle escaping of quotes.

http://www.php.net/manual/en/function.json-encode.php

e.g.

$params = array(
	'menuTextCollapsed' => _t("ImageBrowserPage.MENUTEXTCOLLAPSED"),
	'menuTextExpanded' => _t("ImageBrowserPage.MENUTEXTEXPANDED"),
);
$json = json_encode($params, JSON_HEX_QUOT | JSON_HEX_APOS);

Thank you for answer. At the momen I solved the trouble with

function getParams(){
  return  (	htmlentities('{"nbThumbPerRow": "'.$this->nbThumbsPerRow.'", '.
		'"nbThumbRows": "'.$this->nbRows.'", '.
		'"pauseTime": "'.$this->totalTime.'", '.
		'"transTime": "'.$this->transTime.'", '.
		'"menuTextCollapsed" : "'. _t("ImageBrowserPage.MENUTEXTCOLLAPSED").'", '.
		'"menuTextExpanded" : "'. _t("ImageBrowserPage.MENUTEXTEXPANDED").'", '.
		'"panelToggleText" : "'. _t("ImageBrowserPage.PANELTOGGLETEXT").'", '.
		'"menuSettingText1" : "'. _t("ImageBrowserPage.MENUSETTINGTEXT1").'" ,'.
		'"menuSettingText2" : "'. _t("ImageBrowserPage.MENUSETTINGTEXT2").'"}' ,ENT_QUOTES));
}

I will try you way also.
