[How do I alter this code to display custom error pages?]

Hi everyone, 

 

I am a beginner web designer and a novice php user. I am a regular forum user and understand that you should always do a search and try to find the answer yourself but I have done that and didn't get any results (or I didn't understand them!).

 

So I ask for some assistance - either you can tell me the code or link me to the correct answer.

 

I am working on a website that I have built a enquiry form for and it has a php script for it. I have managed to get the form running properly and got the reCaptcha working correctly (with a custom error page) but I do not understand how to add custom error pages for incomplete email addresses, empty email addresses, or for a blank form? I tried using the same tactic I used for the reCaptcha error page but it didn't work - probably because I was guessing and just tried it in a bunch of different places.

 

The error msg that displays now is just a plain white page with the msg - Email address is invalid appearing at the top left.

While this is suitably functional it doesn't really look like much so I want to build a custom page for each error that could happen.

 

So the code is below - if anyone can point a beginner in the right direction I would be super happy.  :mrgreen:

 

if you need anymore code or other details just tell me and I will post them up.

 

The url of the form page is http://www.sunsolutionshomeimprovement.com/onlinesales.html

 

This is the code I think you will need - I got it from a demo php script that I have modified. As I said I don't have much clue what I'm doing so I just posted it exactly how it looks - if I over did it I apologize... :oops:

 

68.// Validate email field.

69.

70.if(isset($_REQUEST['email']) && !empty($_REQUEST['email']))

71.{

72.

73.if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST['email'])){$errors[] = "Email address may not contain a new line or

74.a colon";}

75.

76.$_REQUEST['email'] = trim($_REQUEST['email']);

77.

78.if(substr_count($_REQUEST['email'],"@") != 1 || stristr($_REQUEST['email']," ")){$errors[] = "Email address is invalid";}else{$exploded_email = explode("@",$_REQUEST['email']);if(empty($exploded_email[0]) || strlen($exploded_email[0]) > 64 || empty($exploded_email[1])){$errors[] = "Email address is invalid";}else{if(substr_count($exploded_email[1],".") == 0){$errors[] = "Email address is invalid";}else{$exploded_domain = explode(".",$exploded_email[1]);if(in_array("",$exploded_domain)){$errors[] = "Email address is invalid";}else{foreach($exploded_domain as $value){if(strlen($value) > 63 || !preg_match('/^[a-z0-9-]+$/i',$value)){$errors[] = "Email address is invalid"; break;}}}}}}

78.

80.

81.// Check referrer is from same site.

82.

83.if(!(isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){$errors[] = "You must enable referrer logging to use the form";}

84.

85.// Check for a blank form.

86.

87.function recursive_array_check_blank($element_value)

88.(

89.

90.global $set;

91.

92.if(!is_array($element_value)){if(!empty($element_value)){$set = 1;}}

93.else

94.

95.

96.foreach($element_value as $value){if($set){break;} recursive_array_check_blank($value);}

97.

98.)

99.

100.)

101.

102.recursive_array_check_blank($_REQUEST);

103.

104.if(!$set){$errors[] = "You cannot send a blank form";}

105.

106.unset($set);

107.

108.// Display any errors and exit if errors exist.

109.

110.if(count($errors)){foreach($errors as $value){print "$value<br>";} exit;}

111.

112.if(!defined("PHP_EOL")){define("PHP_EOL", strtoupper(substr(PHP_OS,0,3) == "WIN") ? "\r\n" : "\n");}

113.

114.// Build message.

 

I don't think there is anymore that is relevant?

 

I just want to reiterate that I know nearly nothing about this stuff so if you could keep your answers simple it would help a lot - cheers!
