If I give an echo the contents of the file appear perfectly, but if I try to run this code the content even being there (echo shows) does not appear in the textarea.

$conteudo =  file_get_contents("$arquivo"); 
          
    
 $conteudo=trim($conteudo);

echo("$conteudo"); //aparece normalmente
//$conteudo = "Eu apareço"; //se eu tirar o comentário vai aparecer o texto 
          
 echo("<script>

window.parent.document.getElementById(\"id_textarea\").value=\"$conteudo\";

</script>");

php javascript

  • No, this textarea is created in index, it finds the element normally because as commented above, if I switch to a string it normally puts in the textarea. Thank you.

  • Got it. What’s in this file_get_contents("$arquivo")? HTML codes?

  • actually anything, I can put text that doesn’t work, I can put tags, in fact the business is so sinister that if I put in the text the test string it doesn’t show, but if I put $content="test" after it took the content of the text it shows.

  • The problem is that if you have a line break in the content will give error in JS.

  • True, now that I’ve seen that if you have line breaks you won’t, even if you’re in Aff quotes, you have a way to solve?

  • Try it like this: $conteudo=addslashes(trim(preg_replace("/\r\n/", "", $conteudo)));

  • It was not, the console shows the same Uncaught Syntaxerror error: Invalid or Unexpected token

I just put no lugar de \" ( is not ' is `even backtick) that javascript accepted. Sometimes I love javascript as my life and sometimes it makes me want to kill myself. Thank you very much.
