passing JavaScript data to PHP

Anon

...
<SCRIPT LANGUAGE="JavaScript">
...
function saveit ( form )
{
var ne = (form.length - 4);
for (var n=1; n<=ne; n++) {
llist = eval ("form.line" + n + ".value");
// llist contins the form data I want to send to the DB
<?
$insq = "insert into table values (0,'$llist');";
$result = mysql_query ($insq);
?>
}

This is what I want to do. Is it possible to do it?

Basically... no. Sorry.

To pass javacript data into php you would have to put them in either a hidden input and submit a form or redirect passing the values through the querystring. Remember that php runs on the server, and by the look of your code your function seems to run on the client.

Good luck.

I am trying to accomplish the same thing, so if I discover a solution, I will post it here.

You can do it, but not the way you did. You just put everything in a form, and post the contents back to your script, only then can you save them to your MySQL table.

So basically your script should look like this :

<?php
if ($REQUEST_METHOD == "POST")
{
// check if data is valid, if not generate error message
if (valid_data())
{
// get all data & save to MySQL
mysql_connect(...);
mysql_query("insert ...");

etc.

// redirect to another page
Header("Location: thanks.html");
exit;

}
}

<body>
<form name="<?=$PHP_SELF?>" method="POST">

... put your form data here ...

</form>
</body>

open a new window with javascript called 'new_window', then use this function to make up a url with all your current form field values:

function save_form()
{
var loc = "saveform.php3?fieldname=" + document.formname.fieldname.value + "&fieldname2";
loc += document.formname.fieldname2.value;

new_window.location = loc;

}

Hope that helps.
