text input field

tommycahir

hi guy's

sorry i know this is a silly question but an cr** at web programming and i have done a few google's on this and am still stumped

basically what i am looking to do is when a text input box has been filled i need to assigned that value to a hidden field on the form

currently my area that the text is inputted into is
Name:<br><input type="text" name="realname" value="your name" size="20">

now i want to assign the value of that to a hidden field like
<input type="hidden" name="subject" value=" the value of realname to be placed ere" />


i know it must be just something simple

thx in advance

you could use onBlur to call a javascript function. onBlur fires when the user clicks out of the textbox ( you could use other commands aswell i think)

<input type="text" name="realname" value="your name" size="20" onBlur="javascript:assign();">

then at the top of the page in a script block

function assign(){
document.getElementById("hiddenFieldID").value = document.getElementById("realname").value;
}

my syntax might be a bit wrong but its the idea i think

hope it helps.

I'm stumped as to why you want to do this. The value is going to be duplicated on a second form field, both will be sent to the server on submission, both are trivial to hack, what do you gain for this extra work apart from requiring the user to enable javascript?

i got it going aqctually shortly afterwards but not exactly the way i would have liked it but it going none the less

thx for help anyways

I just want to make sure you know that a hidden field provides no security, assigning something to that won't stop a person saving the page, manually changing the values in all form fields, and submitting any values they like to your server.
