Input and output array... i think

[faux]

I'm kind of a beginner, but I really need this script and I'm not sure how quite to do it as needed...

 

With some html forms I need it so you can type a name in then click submit, then (with php) it will save that text into a text file or something. Later, when I hit a different button it will randomly display one of those texts/names from before.

What is your question?

I'm asking how can I have the HTML form add a line of text to an php array

[darkfreaks]

yes check into array_push function

[faux]

I don't understand how that will work with my script. Something like...?

<?php
$name = $_REQUEST["name"];
$stack = array();
array_push($stack, $name);
print $stack;
?>
<form name="input" action="index.php" method="get">
Name: <input type="text" name="name" /><br />
<input type="submit" value="Submit" />
</form>

[darkfreaks]

your logic is abit flawed printing $stack will only output ARRAY=>

 

you could do this however

 

$array=array();
$arrayed= array_push($array,$name);

echo $arrayed;

 

then you will get the desired HTML you want with the name.

try

   $names = explode(',', file_get_contents('yourfile.txt'));

   if ( isset($_POST['name']) )
   {
      if ( !ctype_alpha($_POST['name']) )
         throw new Exception('Name can only consist of alphabetic characters');
      array_push($names, $_POST['name']);
      file_put_contents('yourfile.txt', implode(',', $names), FILE_APPEND);
   }
   if ( !count($names) )
      throw new Exception('No names to display');
   shuffle($names);
   echo $names[0];

catch ( Exception $e )
{
   $error = $e->getMessage();
}
if ( isset($error) )
   echo $error;

{

}
if ( isset($error) )
   echo $error;

 

I got one error so far with that.

He forgot a closing bracket for his try block.

Yeah, I tried added one, but same error.

You might need AJAX to show a random name in a box by letting PHP read the text file line by line into an array and then spitting out a random name.
