How do I save form data to a file, as with perl cgi.pm query->save(FILE) ?

blair leavell, markus dinter,
try this if your php.ini contains register_globals=on
<html>
<body>
<?
if (isset($_POST["confirm"]))//posted?
{
//php must have write-access in this directory
$fp=fopen("data.txt","w");//overwrite existing text file
fwrite($fp,var_export($_POST,TRUE));//write post-data
fclose($fp);
}
?>
<form action='<?=$_SERVER["PHP_SELF"]?>' method="post">
name<input type="text" name="name"><br>
city<input type="text" name="city"><br>
telnr a<input type="text" name="telnr[0]"><br>
telnr b<input type="text" name="telnr[1]"><br>
<input type="submit" name="confirm">
</form>
</html>
after execution in data.txt must be something like this:
array (
'name' => 'mad',
'city' => 'max',
'telnr' =>
array (
0 => '23523lk5j23',
1 => '257899',
),
'confirm' => '',
)
OK, I tried this, and the data.txt file it created was null, so I added:
ini_set("register_globals", "1");
as the first line to override whatever the server had (not my server)
but I still got a null file when I did the submit.
Any idea what could be wrong?
I really like your way of saving all the post data, but I can't use it
unless I find out why it won't run right on my server.
Thanks,
Blair
for older versions of php try this:
<?
function var_export($a)
{
$result = "";
switch (gettype($a))
{
case "array":
reset($a);
$result="array(";
while (list($k,$v)=each($a))
{
$result.="$k => ".var_export($v).", ";
}
$result.= ")";
break;
case "string":
$result = "'$a'";
break;
case "boolean":
$result=($a)?"true":"false";
break;
default:
$result=$a;
break;
}
return $result;
}
if (isset($HTTP_POST_VARS["confirm"]))//posted?
{
//php must have write-access in this directory
$fp=fopen("data.txt","w");//overwrite existing text file
fwrite($fp,var_export($HTTP_POST_VARS));//write post-data
fclose($fp);
}
?>
<html>
<body>
<form action='<?=$PHP_SELF?>' method="post">
name<input type="text" name="name"><br>
city<input type="text" name="city"><br>
telnr a<input type="text" name="telnr[0]"><br>
telnr b<input type="text" name="telnr[1]"><br>
<input type="submit" name="confirm">
</form>
</html>
Well, my server seems to have training wheels on it. I enabled
register_globals in my htaccess file, but I still can't seem to
reference GET or POST variables directly, which is probably why your
code doesn't work for me. I am just going to use the old syntax:
fwrite($fp,$_POST['name']);//write post-data
since this works
I will just use pipe delimited key value pairs to store and retrieve the
form data. Primitive but it works.
Thanks for all your help.
Blair
