在按钮的value参数内插入自定义字符串

Question

Hello I am trying to insert custom string inside button Value, but I am facing a problem when I inster the string inside the value parameter the string is appering like text instead as a valuer="" inside the button string. Here is my button code:

$buttons = '<input type="submit" name="Submit" style="width:110px;margin:0 auto;display:block;"  value="'.pll_e('message','wpnotification').'" />' ;

So basicaly I need when this is rendered the result of the function to be shown inside the input button not outside

Instead of the result of this to be <input type="submit" name="Submit" style="width:110px;margin:0 auto;display:block;" value="String Text">

The result is:

String Text
<input type="submit" name="Submit" style="width:110px;margin:0 auto;display:block;"  value="">

So I need this text to apper inside the value tag.

Converting my comment into answer...

I think i know what the problem is. pll_e() function must be echoing the output instead of returning it.

Your function must look something similar to this:

function pll_e($paramA, $paramB) {
    echo $paramA . " " . $paramB;
}

If that's the case, then you can deal with it by capturing the output buffer to a variable and use it on the button like this:

ob_start();
pll_e('message','wpnotification');
$funcValue = ob_get_clean();

$buttons = '<input type="submit" name="Submit" style="width:110px;margin:0 auto;display:block;"  value="'. $funcValue .'" />';

Alternatively, if you have access to the pll_e function... then just change it, so it return the value instead of echo it like this (example):

function pll_e($paramA, $paramB) {
    return $paramA . " " . $paramB;
}

$buttons = '<input type="submit" name="Submit" style="width:110px;margin:0 auto;display:block;"  value="'. pll_e('message','wpnotification') .'" />' ;
