[delickate]

hi guys,

  i need check box validation. if i didn't check it then it must alert error "please agree term and condition".

  if it checked it it should not return and thing.

  i m using following code

function checkBoxes(fld)

  {

if (!fld.checked)

  {

    error ="Please agreed to the Terms and Conditions!";

        return error;

  }

return true;

}

 

it works well. when i didnt check it return error.but if i check it. it again lert "true".

i need to skip return true.if i check it it didnt show alert.

any one know how to?

You dont need a function for such a small thing

 

Try:

 

<?php if(isset($_POST['checkbox'])){ checkbox is checked } else { its not checked } ?>

 

 

or:

function is_checked($checkbox){

    $checkbox = (isset($checkbox)) ? true : false;

     if($checkbox){ return true; }
    else { return false; }

  // OR return $checkbox
  
}

Yeah, I usually just do something like:

<?php
if (isset($_POST['checkbox'])) {
  $checked = 'checked="checked"';
} else {
  $checked = '';
}
echo '<input type="checkbox" name="whatever" value="val" '.$checked.' />';
?>

@delickate,

 

You posted JavaScript not PHP. Which are you wanting: a PHP validation or a JavaScript validation?

 

There is no "checked" property on a POSTed value in PHP.
