[SOLVED] form error messages.

[czukoman20]

How would i make a form that gives you an error message if something isn't filled in

By checking if everything is set, and if it's not, returning an error.  A little bit of common sense goes a long way.  We're not writing it for you, but we'll help you get on the right road to doing it.  Show us what you have so far.

if (!isset($_REQUEST['field'])) { echo "Blank"; }

Well all i have is a simple textbox. in this form

<input type="text" name="fname" maxlength="50" value="<? echo $form->value("fname"); ?>"

Less vague please, that code doesn't tell much. What I told you in my previous post works fine.

<?php

if(empty($_POST['fname']))
{
   $error = 'Please enter your first name';
}


if(isset($error))
{
   echo $error;
}
?>

You should make $error an array so you can store multiple errors, or make a FormError class.

Typically when validating multiple fields I will either use an array or concatenate the strings.

 

For the original poster we are talking about this.....

 

<?php

if(empty($_POST['fname']))
{
   $error['first_name'] = 'Please enter your first name';
}

if(empty($_POST['another_field']))
{
   $error['some_field'] = 'Please enter data in this field ';
}

if(isset($error))
{
   foreach($error as $k=>$v)
   {
        echo $v.'<br>';
   }
}
?>

 

OR

<?php

if(empty($_POST['fname']))
{
   $error .= 'Please enter your first name<br>';
}

if(empty($_POST['another_field']))
{
   $error .= 'Please enter data in this field<br>';
}

if(isset($error))
{
   echo $error;
}
?>
