Keeping non-sensible info into a formulary

kyru · Feb 12, 2009

Let's suppose I have an application with several formularies, before submitting the formulary the user can check what he has introduced, all non-sensible information in those formularies that was given before by the user must be filled automatically. I've tried doing it this way:

<?php
if ($_POST['enviar'])
{
echo (nl2br("Button pressed\n"));
echo(nl2br("The content of texto is ".$_POST['texto']."\n"));
print '<a href=otro.php>Return to form</a>';

}
else {
$temp=$_POST['texto'];
print '<form action="otro.php" method="post">
<input type="submit" name="enviar">
<input type="text" name="texto" value="$temp">
<input type="text" name="texto2">';
}
?>

So the field text would take the value $_POST['texto'] always the form gets an instance, but the html page prints $temp literally in the textbox instead, sigh.

I'm not too sure if the $_POST['texto'] keeps the info after pressing the link to go back to the form. So, I'd better just put the form info into a temp file and get the info from that file later. Anyway how I'm supposed to tell the html page that it takes that value by default?

Thanks in advance.

You have this block in a single quote, which won't interpolate.

Code:

print '<form action="otro.php" method="post">
      <input type="submit" name="enviar">
      <input type="text" name="texto" value="$temp">
      <input type="text" name="texto2">';

Fix by doing:

Code:

print '<form action="otro.php" method="post">
      <input type="submit" name="enviar">
      <input type="text" name="texto" value="' . $temp . '">
      <input type="text" name="texto2">';

Thanks, it works great now, it's necessary to use a temp file anyway.

rather than single quote breakout you might consider using heredoc instead. it is a bit slower to parse but much easier to use for html blocks

Code:

echo <<<HTML
      <form action="otro.php" method="post">
      <input type="submit" name="enviar">
      <input type="text" name="texto" value="$temp">
      <input type="text" name="texto2">
HTML;
