Exploding an array...

[mattyvx]

Hi!

 

My goal is to reduce the ammount of code im using in a PHP script.

 

I have a php form which, when submitted is validated and error messages (if applicable are set).

 

For example;

if(strlen($user) < 5)
{
$error = "yes"
$errormsg['User'] = "The username must be greater than 5 characters";
}
if(strlen($lastname) < 3)
{
$error = "yes"
$errormsg['Surname'] = "The surname must be greater than 3 characters";
}

 

So these error messages are stored in the array $errormsg.

 

Now if $error is set to yes the form page shows the error messages by using

 

echo $errormsg['User'];
echo $errormsg['Surname'];

 

The example only uses two fields but when i have many fields thats alot of echoing...

 

Can i "explode" the array / is there a more efficient way of displaying the array.

 

Thanks

yes

<?php
if(count($errormsg)) {
  print implode("<br />",$errormsg);
}
?>

You could implode the array, or to save repeating yourself could use a loop to go through the array and echo each value individually.
