Are your 'textboxes' in different rows or columns?

Do you have 10 rows, each with a 'textbox' in?

Please provide information to how your databse is structured, as it is key to how we write the script to solve the problem

Hi,

You may loop for all such values and can set button property accordingly. with editing of mattsters's answer, script can be something like below:

$flag = true;
for ($i=1; $i<=26; $i++) {
    if(!not_null($result[0]['Heamogram_'.$i])) {
        $flag = false;
        break;
    }
}
if ($flag == false)
    $property = "disabled='disabled'";

and then you mmy echo $property wherever you want in your script/code

you're going to want to do this client side (js) so that you can detect when a user has input text into one of the boxes

//my sudo code (write your own code)
func boxchanged() {
    if has value set enabled
    else call checkboxes()
}

func checkboxes() {
    foreach box {
        if box has value {
            break
            set enabled
        }
    }
    set disabled
}
//add boxchanged() to the onchange for each box

my sample code is below

<?php 
@require_once 'config/config.php';
@require_once 'config/session.php'; 
@require_once 'class/dbclass.php';
@require_once 'class/EmpRegister.php';

$emp = new EmpRegister();
$EmpID = $_REQUEST['EmpID'];
if($EmpID != NULL){
    $result = $emp->get($EmpID);
    if($result == NULL){
        $EmpID = '';
    }
}
?>

<?php if(!not_null($result[0]['Heamogram_26'])){echo "disabled";}?>

mattster 195 Practically a Master Poster Featured Poster · Answer 3 · 2014-08-12T16:36:48+00:00

Or this will do the same thing:

<?php if(!not_null($result[0]['Heamogram_26'])){echo "disabled='disabled'";}?>
