creating javascript dynamically with php

Hi,

I have been trying to populate some javascript with values from php variables but cannot get the syntax correct.

I have read the php manuals and searched on this forum but cannot find any examples to learn off.

Bascially I am passing two php variables to a php page which tries to create the javascript with the php variables as follows

<?php
$editor = "editor";
$form_field = "field1";

echo "\n document.".$editor.$form_field.".value = 1;"

what I want to do is dynamically build the javascript so that I can update a hidden form field on the same page.

I want the output when php has finished to be

document.editor.field1.value =1;

php complains about the line. I think its because I do not fully understand how to join static text (in quotes) with php variables.

any help much appreciated.

You can write it look like:

<?php
$field1_value = 1;
?>
<input type="hidden" name="field1"
value="<?php echo $field1_value; ?>">

echo "\ndocument.$editor.$form_field.value = 1;"

you don't have to exit from the quotes to have the value printed.
