foreach error

[adammc]

Hi.. I am in trouble again

I am getting the following error when one of the validation checks (empty) is true.

Warning: Invalid argument supplied for foreach() in .......

elseif ($install==step1a){


// Begin Form Error Checking
    $errors = array();
    

// Check for a database password
if(empty($dbpass)){
      $errors = 'Please enter a password.';
   } 
   
// Check for a database username
if(empty($dbuser)){
      $errors = 'Please enter a username.';
   }   

// Check for a database host
if(empty($host)){
      $errors = 'Please enter a host name.';
   }  
   
// If form validation went okay and there were no errors, continue.    
    if (empty($errors)) {


// do something here


} else { // if errors array contains a value
    
        echo "<table align=\"center\"><tr><td>The following error(s) occurred:<br />";
        
            foreach ($errors as $msg) { // Print each error.
            echo "* $msg<br />\n";
            }
            
        echo '</td></tr></table>';
        
    } // End of if (empty($errors)) IF. 

Can anyone possibly help?

You are setting the errors as a string when you should be setting them in an array. Try this:

elseif ($install==step1a){





// Begin Form Error Checking

    $errors = array();

    



// Check for a database password

if(empty($dbpass)){

      $errors['pass'] = 'Please enter a password.';

   } 

   

// Check for a database username

if(empty($dbuser)){

      $errors['user'] = 'Please enter a username.';

   }   



// Check for a database host

if(empty($host)){

      $errors['host'] = 'Please enter a host name.';

   }  

   

// If form validation went okay and there were no errors, continue.    

    if (empty($errors)) {





// do something here





} else { // if errors array contains a value

    

        echo "<table align=\"center\"><tr><td>The following error(s) occurred:<br />";

        

            foreach ($errors as $errtype => $msg) { // Print each error.

            echo "* $msg<br />\n";

            }

            

        echo '</td></tr></table>';

        

    } // End of if (empty($errors)) IF.

thank you soo much it works a treat
Not sure what I had done wrong though as I have used variation of that code for months on heaps of different apps with no probs.
