Hidden field script needed i think

MikeFantana · 18-12-2008 5:39pm #1

Hi
I have the following set of radio buttons, each with a different value. Basically depending on which is selected i need the hiddenfield to hold whether it is Euro/Sterling or Dollar. Would anyone be able to help me out here.

Euro<input name="Currency" type="radio" value="1" checked id="currency">
Sterling <input name="Currency" type="radio" id="currency" value="<%=(rsSterlingVal.Fields.Item("CurrencyVal").Value)%>">
Dollar<input name="Currency" type="radio" id="currency" value="<%=(rsDollarVal.Fields.Item("CurrencyVal").Value)%>">

<input type="hidden" name="hiddenField" id="hiddenField">

Why don't you just read the contents of the form, as normal, and then put the value of the radio button (or a corresponding value) in a variable? You can then reference that variable in the hidden field.

For example -

<?php
// myForm.php

if ($_GET['hiddenfield'])
 $hiddenField = $_GET['hiddenfield'];
else
 $hiddenField = "";

echo '
<html>
<body>
<form method="get" action="myForm.php">
<!-- put your radio buttons here -->
<input type="hidden" name="hiddenField" value="<?=$hiddenField;?>">
<input type="submit" value="Submit">
</body>
</html>';

?>

Basically,

This is an insert statement into a table which will hopefully catch the 'the currency and the currencyrate e.g. ''Dollar' for Currency and '0.78' for the currency Rate. I would like to achieve this by one selection as opposed to 2 selections.

?>

I guessed from your code you were using ASP, but PHP syntax is fairly similar so it should be readable.

The user should only choose his currency. It is up to you to define the currency rate.

Currently the currency rate is pulled in using a seperate table via a recordset e.g. <%=(rsSterlingVal.Fields.Item("CurrencyVal").Value)%> which inturn is inserted in the table no problem, its just i need to be able to trap the currency type when inserting.

you could use Javascript. something like this:

<script type="text/javascript">
function toggleCurrency(radioButton)
{
hiddenField.text = radioButton.value;
}
</script>

Euro<input name="Currency" type="radio" value="1" checked id="currency" value="Euro" onclick="toggleCurrency(this)">
Sterling <input name="Currency" type="radio" id="currency" value="<%=(rsSterlingVal.Fields.Item("CurrencyVal").Value)%>" onclick="toggleCurrency(this)">
Dollar<input name="Currency" type="radio" id="currency" value="<%=(rsDollarVal.Fields.Item("CurrencyVal").Value)%>" onclick="toggleCurrency(this)">

<input type="hidden" name="hiddenField" id="hiddenField">

Thanks for that code, but its not catching what each buttons currency is. Below is my whole page (minus the insert statement)

If the rate is already in the database, then just do another SQL statement upon the form submission to get it.

It would be very easy for anyone with a bit of JavaScript knowledge to change the contents of a hidden form field.

Yeah, I'm having a hard time understanding the OPs reasoning.

OP: Is this a commerical application you are developing (i.e. you don't have to use hidden form values), or is it some sort of assignment where you must use hidden form values?

Hidden field script needed i think
