js array -> php array

[Roderik]

Hi,

I have an array in javascript of which the contents are manipulated by
the user. When he is done, he calls a function to reload the page. Then
conclusion depending on the input should be printed.
The problem is, how can I use the javascript array in this php file?
Is it neccesary to use numerous hidden form fields for this purpose?

regards,

Roderik

cause javascript is executed on client browser and php script on server
: yes.

you have 3 methods for passing javascript values to your php script :

1- hidden (or not) fields of a form ;
2- link with url like www.script.php?var1=val1&var2=val2...
/!\ : you must serialize ?var1=val1&var2 =val2... :
3- cookie string

further to roderick's reply:

an array passed back to the server in a hidden form field will arrive in
your PHP script as a comma-delimited list, either in a POST variable, or
a GET variable.

this example uses the POST method --

<form name="testForm" action="test.ph p" method="post">
<input type="text" name="testText" >
<input type="hidden" name="testHidde n">
<input type="submit">
</form>

<script language="javas cript">
testArray = new Array (1,2,3);
document.testFo rm.testHidden.v alue = testArray;
</script>

<?php

if (isset($_POST['testHidden'])) {
$tok = strtok($_POST['testHidden'], ",");
while ($tok) {
echo "element = $tok<br>";
$tok = strtok (",");
}
}

?>
