form validator???

[ball420]

i want to make a couple of my fields required but i'm not sure how to go about it also i want to make the next step go to a url not echo just some words. thanks a million for all your help!!!

[trq]

form.php

<form action="process.php" method="post">
  <input type="text" name="foo">foo?
  <input type="submit" name="submit">
</form>

 

process.php

<?php

  if (isset($_POST['submit'])) {
    if (empty($_POST['foo'])) {
      echo "foo is a required field<br />";
    }
}

?>

if($_POST['name'] == ""){
     echo "Please fill in the name";
} elseif($_POST['phone'] == ""){
     echo "Please fill in the phone";
} else{
     //make the operations
}

 

To go to a url u can use header('location: page.php') or alternatively meta refresh or javascript refresh.

You're missing the closing } for your if-else.

You just have the ?> without closing the else.

thanks that fixed that problem but now it echo's both

 

foo is a required field

Data has been submitted to tony@yourmom.com!

thanks again fo rthe hlp

Well read through the code and see why that is. You never tell it anything about not sending if one of the required fields is empty.

You might consider setting a variable like $ok and setting it to false if it's not okay to send the form, then check it before emailing.

Simply:

 

if (empty($_POST['name_field'])) {
      echo "foo is a required field<br />";
} else{
      //the other code
}

 

So u check the name_field, if is empty show the error, else make the processing.
