How do I transfer captured values from my URL into hidden fields on my html form

I captured the values using the following javascript code in my html form:

<script type="text/javascript">
<!--

function querySt(ji) {
    dwnstr = window.location.search.substring(1);
    dwnstr = dwnstr.toLowerCase();
    gy = dwnstr.split("&");
    for (i=0;i<gy.length;i++) {
        ft = gy[i].split("=");
        if (ft[0] == ji) {
            return ft[1];
        }
    }
    return "";
}

cust_lat = querySt("lt");
cust_long = querySt("lg");

document.write(cust_lat);
document.write(cust_long);

-->
</script>

As you can see I wrote the captured variables to my screen, so I know that the code works.

I need the value of the variables cust_lat & cust_long put into two hidden fields on my form (form1) replacing the default values of 0

type=hidden name=cust_lat><input style="WIDTH: 79px; HEIGHT: 22px" value="0" 
type=hidden name=cust_long><input style="WIDTH: 81px; HEIGHT: 22px" value="0" 

the result is then passed to index.php using the following line:

开发者_Go百科<form method="get" name="form1" action="index.php">

Right now the fields are coming through to mysql as the defaults: 0 0

I just need to replace these default values with the captured values.

I hope someone can help

Thank you,

$_GET['fieldname'] is the equivalent in php as request.querystring("variable_name") is in asp

give your hidden inputs an id and use document.getElementById('hiddenbox').value="The Value Here"

You need to use DOM javascript to set the values. First, specify an id for each of your elements:

<input type='hidden' name='cust_lat' id='cust_lat'> <input type='hidden' name='cust_long' id='cust_long'>

Then, use document.getElementById('cust_lat').value = whatever; in your page load javascript.

<type=hidden name=cust_long value=$_GET['fieldname']>

PHP method:

<?php
    $lt = (isset($_GET['lt']) && is_numeric($_GET['lt'])) ? (float)$_GET['lt'] : 0;
    $lg = (isset($_GET['lg']) && is_numeric($_GET['lg'])) ? (float)$_GET['lg'] : 0;

    echo <<< HTML
<input type="hidden" name="cust_lat" value="{$lt}">
<input type="hidden" name="cust_long" value="{$lg}">
HTML;
?>
