Question

echoing checkbox value

I have a form, and if it is not sent, the form is echoed.  here is part of my code that is being echoed:

echo "...<input type='checkbox' name='noIdentity' id='noIdentity' value='noIdentity'
    <?php
    if(isset($_POST[errors]) && isset($_POST[noIdentity])) {
        echo 'checked=checked';
    }
    ?>..."

The only problem is, if the value is checked, when i come back to it with the rest of the form errors, it is not checked.  why isn't it being checked?

change this $_POST[noIdentity]

to this $_POST['noIdentity']

and do the same for your others

hm, when i do that, i get this error:

Parse error:  syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in /homepages/45/htdocs/uploader/member_contact.php on line 238

I guess it doesn't like when I add the single quotes...

My gut is telling me that the noidentity isset check is failing.  How are you setting $_POST[errors]?  Are you submitting to a page and then redirecting back to the form and setting $_POST[errors] on that next page?  If so, then what I suspect is happening is during the transition from page 1 -> page 2 -> page 1 is that your variables are not being reset.  Have you considered storing the variables in a session during this process instead and then passing the session variables back if the form fails?

Only way to be more certain is to see more of the code.

i am setting post errors by doing something like this (on the same page):

if submit,

if(empty($_POST['message'])) {
        $errors[] = "Please fill in a message.";
    }

then:

if (isset($errors) && !empty($errors)) {
    $result = count($errors);
   
    for ($i=0; $i<$result; $i++) {
          echo "<p><div class='error'><img src='../Images/error_image.png' width='16' height='16' /> $errors[$i]</div><p>"; 
    }
}

what is the best way to submit a form?  on the same page, or redirect?  or does it depend on the situation?
