**guillermobytes** · Apr 13 '10, 10:21 PM

**lisa007** · Apr 13 '10, 10:24 PM

**guillermobytes** · Apr 13 '10, 10:28 PM

what values do you want to give to A B and C?
also what are you trying to do with the function Name() ?

if look at this array

Code:

if ($_POST['campustype']=='')
        $arrErrors['campustype'] = 'Please select category.';

		which is then called

<p<?php if (!empty($arrErrors['campustype'])) echo ' class="formerro"'; ?>>

    <?php if (!empty($arrErrors['campustype'])) echo '<br /><span class="errortext">'.$arrErrors['campustype'].'</span>'; ?><br/><label for="incampus">Select Category</label>
<input type="radio" name="campustype" value="in" onclick="toggleSelect('in');" /><label for="campustype">Music</label>

<input type="radio" name="campustype" value="off'" onclick="toggleSelect('off');" /><label for="campustype">Sports</label>

<input type="radio" name="campustype" value="1" onclick="toggleSelect('1');" /><label for="campustype">Art</label>

</p>

now i want to do the same with the drop down but if if all 3 drop downs have the same name the user will have to select the drop down 3 times in order to pass
is the original work i had

Code:

<?php
// Create an empty array to hold the error messages.
$arrErrors = array();
//Only validate if the Submit button was clicked.
if (!empty($_POST['Submit'])) {
    // Each time there's an error, add an error message to the error array
    // using the field name as the key.
    if ($_POST['name']=='')
        $arrErrors['name'] = 'Please provide your name.';
    if ($_POST['email']=='')
        $arrErrors['email'] = 'A valid email address is required.';
    if ($_POST['phone']=='')
        $arrErrors['phone'] = 'Please provide your phone number.';
		
		
		if ($_POST['campustype']=='')
        $arrErrors['campustype'] = 'Please select category.';
		
		
		
		
		if ($_POST['howt']=='')
        $arrErrors['howt'] = 'select one field.';
		
		
		
		
		
    if (count($arrErrors) == 0) {
        // If the error array is empty, there were no errors.
        // Insert form processing here.
    } else {
        // The error array had something in it. There was an error.
        // Start adding error text to an error string.
        $strError = '<div class="formerror"><p><img src="/images/triangle_error.gif" width="16" height="16" hspace="5" alt="">Please check the following and try again:</p><ul>';
        // Get each error and add it to the error string
        // as a list item.
        foreach ($arrErrors as $error) {
            $strError .= "<li>$error</li>";
        }
        $strError .= '</ul></div>';
    }
}
?>

i'm sorry i don't want you to loose your time nor i want to loose mine, your code is very very messy and I have no time to try to understand it, so please try to explain in words:
- what you have achieved so far,
- what you are trying to achieve //output
- what is the data that you have to treat to achieve what you want//input

**lisa007** · Apr 13 '10, 10:53 PM

i have 3 drop dwon list as long the user select from one of the 3 drop down list pass the validation but if user doenst select from none of them display error message so the user is forced to select at at least form one drop down list and one only if none display error message

**guillermobytes** · Apr 13 '10, 11:16 PM

I will try to help and i hope im not mis answering.

lets say drop down lists are called 'a', 'b' and 'c':
first ensure at least one has something selected otherwise log an error message:

Code:

//first isolate the 3 drop downs
$dDwns = array();
$dDwns['a'] = $_POST['a'];
$dDwns['b'] = $_POST['b'];
$dDwns['c'] = $_POST['c'];
//now perform the checks
$filledDD = array(); //will contain filled drop downs
foreach ($dDwns as $name => $value) {
   //every not empty drop down will be rememebered
   if ('' !== $value) {
       $filledDD[$name] = $value;
   }
}
//now ensure at least the minimum of dropDowns have been filled
if (count($filledDD) === 0) {
   $errorMessages['dropDown'] = 'You must at least fill one of the 3 drop downs';
   $noContinueErrorCount++; //every time a "fatal" error is triggered increase count (fatal: the user can't go to next step)
} else {
   //do what you want with the data of the filled forms $filledDD
}

//now present the data as you want
if ($noContinueErrorCount > 0) {
   //render the current form
   formNumber1($validFields, $errorMessages);
} else {
   //render the next form
   formNumber2();
}
