 Posted: Mon Nov 26, 2007 1:34 am Post subject: Validate contact form with Smarty |
 |
|
I've posted around various places before regarding this without any luck. I have a working php "contact us" form on my website using a smarty template.
I really need to add some form of validation to the email and phone number fields on the form.
A few other forums suggested using javascript to validate, but when I add javascript to the head.tpl file for my contact page, nothing seems to happen. The form gets sent without being stopped
Original working code (no validation):
| Code: | <?php
require_once('libs/Smarty.class.php');
$smarty = new Smarty;
$smarty->compile_check = true;
$smarty->debugging = false;
if (isset($_POST['action']) && $_POST['action'] == 'Submit request')
{
$body = '';
$body .= 'How did you hear about Dive Adventures? ' . $_POST['heard'] . "\n";
$body .= "\n";
$body .= '* Your adventure' . "\n";
$body .= 'Which destination are you interested in? ' . $_POST['holiday'] . "\n";
$body .= 'When do you intend to travel? ' . $_POST['month'] . ' ' . $_POST['year'] . "\n";
$body .= 'What type of diving do you enjoy doing? ' . $_POST['diving_type'] . "\n";
$body .= 'Number of guests: ' . "\n";
$body .= 'Adults: ' . $_POST['adults'] . ' (' . $_POST['adult_divers'] . ' are divers)' . "\n";
$body .= 'Children: ' . $_POST['children'] . ' (' . $_POST['child_divers'] . ' are divers)' . "\n";
$body .= 'Infants: ' . $_POST['infants'] . ' (' . $_POST['infant_divers'] . ' are divers)' . "\n";
$body .= 'Comments: ' . "\n";
$body .= $_POST['comments'] . '.' . "\n";
$body .= "\n";
$body .= '* Your details' . "\n";
$body .= 'Name ' . $_POST['name'] . "\n";
$body .= 'Email ' . $_POST['email'] . "\n";
$body .= 'Address ' . $_POST['address'] . "\n";
$body .= 'City ' . $_POST['city'] . "\n";
$body .= 'Postcode ' . $_POST['postcode'] . "\n";
$body .= 'State ' . $_POST['state'] . "\n";
$body .= 'Country ' . $_POST['country'] . "\n";
$body .= 'Contact by telephone? ' . ($_POST['contactbytelephone'] ? 'Yes' : 'No' ) . "\n";
$body .= 'Telephone number ' . $_POST['phone'] . "\n";
$body .= 'Monthly newsletter? ' . ($_POST['receivenewsletter'] ? 'Yes' : 'No' ) . "\n";
//echo str_replace("\n", '<br>', $body);
$to = 'divesydney@optus.com.au';
$from = "diveadventures <sydney@diveadv.com.au>";
$subject = "Holiday information - From www.diveadventures.com.au";
$headers = "From: $from";
mail($to, $subject, $body, $headers);
$smarty->assign('submit', 1);

I've tried to add javascript code from the "phpForms" Demo to the head.tpl file. I added this, and tried to match the name="" for the fields I want to be checked for content
| Code: |
<script language="JavaScript">
<!--
var aIds = Array( 'pg_801e316097' );
function ChangePage( to_hide, to_show )
{
var tbl_hide = document.getElementById( aIds[to_hide] );
var tbl_show = document.getElementById( aIds[to_show] );
if ( typeof(tbl_hide)=='object' && tbl_hide!=null )
if ( typeof(tbl_show)=='object' && tbl_show!=null )
{
tbl_hide.style.display = 'none';
tbl_show.style.display = '';
}
}
function NotEmpty( old_res, id, field_title )
{
if ( old_res==0 )
{
var el = document.getElementById( id );
if ( typeof(el)=='object' && el!=null )
if ( el.value=='' )
{
alert( 'You should fill "' + field_title + '"' );
return 1;
}
}
return 0;
}
function Email( old_res, id, field_title )
{ // test
if ( old_res==0 )
{
var el = document.getElementById( id );
if ( typeof(el)=='object' && el!=null )
{
var re = /^[a-zA-Z0-9_\.\-]+@([a-zA-Z0-9][a-zA-Z0-9-]+\.)+[a-zA-Z]{2,4}$/;
if (el.value.search(re) != -1 ) return 0;
else
{
alert( '"'+field_title+'" must be email' );
return 1;
}
}
}
return 0;
}
-->
</script>
|
Can anyone please post any helpful suggestions about the simplest and most effective way I can enable field validation for the name, email address and phone number.
I just want something that will check that the fields are filled, I don't really need complex format validation. |

Thanks for the reply. Wouldn't the smarty validate plugin only work for the PHP code? At the moment the PHP side of things works ok.
I just want to add code (javascript OR php, whatever is simpler) that will stop the form from being emailed to me if a field is left empty.
I tried using the littoral tags, and I stopped getting error messages, but the form was still being emailed to me when the fields were empty  |

well for an example here is a simple form
| Code: |
<script type='text/javascript'>
function validateForm(form)
{
error = "";
if(form.name.value == "")
{
error += "You must enter in your name.\n";
}
if(form.email.value == "")
{
error += "You must enter in an email\n";
}
if(error != "")
{
alert(error);
return false;
}
return true;
}
</script>
<form name="main" onSubmit="return validateForm(this);">
Name: <input type="text" name="name">
Email: <input type="text" name="email">
<input type="submit" value="Submit">
</form>
|
You can then keep adding more fields as you need[/code] |

try in php
| Code: | if(empty($this) || empty($this))
{
$error = 'You didn't fill out all the fields.';
}
//assign all info
$smarty->assign(array(
'HOLIDAYS' => $_POST['blah'],
'DOB' => $_POST['blah'])
);
// redisplay form with post info inside
|
the form should have <input value={$HOLIDAYS} even if there is not data / assigned var created yet incase they have to be returned to the form.
But I think javascript will be the best way to avoid possible syntax issues.

Thanks for your reply. It's taken me a few months on and off (as a javascript and PHP newbie), but I've replaced the Smarty PHP page with a new javascripted page which successfully rejects forms without a contact email or phone number 
The smarty-based page that our previous webmaster set up just didn't lend itself to any easy form of validation/rejection at all.
Thanks a lot to those who replied. For anyone who might have a similar problem, I used the jscript & PHP code written lower down on this page as a template:

It took a while to customise what I needed, but it seems to work great for me at the moment |
