Autosend to post from Select Box

[jamesflynn]

Hi,

I'm trying to setup a select pulldown that once you click on a selection from the select box it will autosend the results (without clicking submit). But the only way I know how to do that is through some JavaScript that sends it as part of the URL string (get). But I want it to be sent as a form submit in a POST (I do one master if submit at the top and it would make the code alot cleaner if I could just do one master if (submit)

Then under that do a check for the if($select1), and under that if($select2). etc.

Thanks for any help in advance.

This can be done only with JavaScript. You can invoke submit method for your HTML form. Post here your code, so we can discuss it.

This is the JavaScript function I'm using for the autosend

<script type="text/javascript" language="JavaScript">
<!--
function jump(fe){
var opt_key = fe.selectedIndex;
var uri_val = fe.options[opt_key].value;
window.open(uri_val,'_top');
return true;
}
//-->
</script>

and within the select box I call

<select name="fieldname" onChange="return jump(this);" size="1">

So this script just isn't doing what I need because that just sends it to the URL string. I need to be able to auto send submit as POST.

Thanks for any help

so your SELECT have to be enclosed into FORM tags like

<script type="text/javascript" language="JavaScript">
<!--
function jump(fe){
var opt_key = fe.selectedIndex;
var uri_val = fe.options[opt_key].value;
top.document.forms[0].submit();
return true;
}
//-->
</script>

<FORM NAME="name" ACTION="script address" METHOD="POST">
<select name="fieldname" onChange="return jump(this);" size="1">
</FORM>

Thanks for your comment. I tried that and I get the page returnded back without any errors but it doesn't look like any of the variables are passed through the post. I did a

<?php
$field1= $POST['field1'];
$field2 = $POST['field2'];

echo $field1;
echo $field2;
?>

at the top just to check and see if it was passed and nothing was displayed. I send the form like this

<form method="POST" action="<?php echo $_SERVER['PHP_SELF']?>" name="name">

with the select options set as

<select name="field" onChange="return jump(this);" size="1">

Also I do a master if(submit) in the main part of the code

if (isset($_POST['submit'])) {

setup link to DB then narrow down by field name

if (isset($_POST['field1'])) {

After it reads the data will it pickup the autosent select as came from form 'submit'?
Thanks for any help
