readonly textbox

hazel999

Anyone knows how to control textbox(readonly=true and readonly=false) with checkbox beside each, upon checking the selected checkbox, readonly will be equal to false, other than that, it would be true(so that user cannot modify). How do i control it(textbox) using php code?????
Any help would be appreciated!!!! Im at a loss now

Unless you want to send a form each time they select a checkbox, you can't do this with PHP. PHP is a server-side language - textboxes and checkboxes don't exist to PHP.

If you'd like to use Javascript, however, you would do something like this:

<script type="text/javascript">
function changeBox(newValue) {
     document.getElementById('theTextbox').readonly = ((newValue == true) ? false : true);
}
</script><input type="checkbox" onclick="changeBox(this.checked)" /> Enable textbox
<input type="text" name="whatever" id="theTextbox" />

(Untested)

EDIT: Now that I think about it, you might need to change ".readonly" to ".style.readonly" in the JS... I don't remember where the readonly attribute is.

this works - even in firefox, surprisingly enough:
