PHP Form Errors

aleister1987 · October 20, 2010

I have created (modified a tutorial) a PHP Validation Form with validation. I am getting a blank page and cannot view it.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1); ?>
<?php

function VerifyForm(&$values, &$errors)
{
    // Do all necessary form verification

// Validate Model Number
    if (strlen($values['model']) < 4)
        $errors['model'] = 'Model Number too short';
    elseif (strlen($values['model']) > 50)
        $errors['model'] = 'Model Number too long';

// Validate Price
if (is_numeric($values['price']) == 0)
        $errors['price'] = 'No Price has been entered';

// Validate Product
if(($values['product'])=='please_select')
	$errors['product'] = 'No Product has been selected';

// Validate Image
if ((($_FILES["photo"]["type"] != "image/gif")
	|| ($_FILES["photo"]["type"] != "image/jpeg")
	|| ($_FILES["photo"]["type"] != "image/pjpeg"))
	&& ($_FILES["photo"]["size"] > 2000000))
	$errors['photo'] = 'Image format must be either JPG/JPEG/GIF or PNG';

// Validate Description
if (strlen($values['description']) < 10)
        $errors['description'] = 'Description is too short';
        
    return (count($errors) == 0);
}

function DisplayForm($values, $errors)
{
    ?>

You're missing a bunch of semi-colons at the end of your statements. Every php statement must end with a > ; <

phprocker · October 21, 2010

Most of your if statements are also missing curly braces.

Proper use is as follows:

<?php
if ($example == 'example') 
{
someoutput();
}
?>

Pikachu2000 · October 21, 2010

<?php = is not valid syntax. <?php echo is.

Don't use this: action="<?php echo $_SERVER['PHP_SELF'] ?>" as it presents an XSS vulnerability. To submit a form to itself, either use action="" or specifiy the name of the script.

aleister1987 · October 21, 2010

@Pikachu2000

<?php = is not valid syntax. <?php echo is.

I don't get what you are saying. You can have the <?php in a line without actually <?php echo. "This is basic stuff".

:shrug:

Pikachu2000 · October 21, 2010

Yes it is basic stuff, and this is not valid syntax:

<?php =

If you were logging errors, you'd see: PHP Parse error: syntax error, unexpected '=' in . . . in your log file.

Im still getting a blank page even after correcting all the errors.

Here is my new code:

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1); ?>
<?php

function VerifyForm($values, $errors)
{
    // Do all necessary form verification

// Validate Model Number
    if (strlen($values['model']) < 4);{
        $errors['model'] = 'Model Number too short';}
    elseif (strlen($values['model']) > 50);{
	$errors['model'] = 'Model Number too long';}

// Validate Price
if (is_numeric($values['price']) == 0);{
        $errors['price'] = 'No Price has been entered';}

// Validate Product
if(($values['product'])== 'please_select');{
	$errors['product'] = 'No Product has been selected';}

// Validate Image
if ((($_FILES["photo"]["type"] != "image/gif");
	|| ($_FILES["photo"]["type"] != "image/jpeg");
	|| ($_FILES["photo"]["type"] != "image/pjpeg");
	&& ($_FILES["photo"]["size"] > 2000000)));{
	$errors['photo'] = 'Image format must be either JPG/JPEG/GIF or PNG';}

// Validate Description
if (strlen($values['description']) < 10);{
        $errors['description'] = 'Description is too short';}
        
    return (count($errors) == 0);
}

Im totally confused now, any more help

Pikachu2000 · October 21, 2010

You have a bunch of semicolons in places where they don't belong, and still have the equals signs where it doesn't belong, after every <?php echo. You should also turn on error reporting in your php.ini file so these problems are displayed to you.

This now has no parse errors, but obviously I didn't test it for functionality.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1); ?>
<?php
function VerifyForm($values, $errors) { 
// Do all necessary form verification
// Validate Model Number
if (strlen($values['model']) < 4) {
	$errors['model'] = 'Model Number too short';
} elseif( strlen($values['model']) > 50); {
		$errors['model'] = 'Model Number too long';}
		// Validate Price
		if (is_numeric($values['price']) == 0){
			$errors['price'] = 'No Price has been entered';}
			// Validate Product
			if(($values['product'])== 'please_select');{
				$errors['product'] = 'No Product has been selected';}
				// Validate Image
				if ((($_FILES["photo"]["type"] != "image/gif")
				|| ($_FILES["photo"]["type"] != "image/jpeg")
				|| ($_FILES["photo"]["type"] != "image/pjpeg")
				&& ($_FILES["photo"]["size"] > 2000000))) {
					$errors['photo'] = 'Image format must be either JPG/JPEG/GIF or PNG';}
					// Validate Description
					if (strlen($values['description']) < 10);{
						$errors['description'] = 'Description is too short';}
						return (count($errors) == 0);
}
function DisplayForm($values, $errors)
{

aleister1987 · October 21, 2010

great some doughnut told me to put semicolons in and now they shouldn't be in there lol.

Thanks for the input pikachu2000, i will have another go lol.

aleister1987 · October 21, 2010

@Pikachu2000

What semicolons are in the wrong place and equal signs where?

Pikachu2000 · October 21, 2010

The code I reposted has those corrections already made . . .

aleister1987 · October 21, 2010

Oyeah sorry, i just ran it and the page displays, Thankyou.

However, now i keep getting aload of errors e.g. Notice: Undefined index: model.

Is this because it cannot see the variables?

Pikachu2000 · October 21, 2010

If you attempt to use the value of a variable before it's been defined, you'll get the 'Undefined' warning. To take care of those, you need to check for its presence before using it.

Causes 'undefined index: email' warning if the form hasn't been submitted:

$email = $_POST['email'];

Checks for the value before trying to use it, so no warning:

if( isset($_POST['email']) ) {
     $email = $_POST['email'];
} else {
     $email = '';
}

// Can also be done "shorthand" using ternary syntax

$email = isset($_POST['email']) ? $_POST['email'] : '';

aleister1987 · October 21, 2010

Im sorry to be a pain, do you know exactly where i would put them in my script?

Pikachu2000 · October 21, 2010

I can look it over some more, but it's probably going to take me a while.

aleister1987 · October 21, 2010

If you could that would be amazing.

Pikachu2000 · October 21, 2010

I normally don't go through an entire script for someone like this, bu I know you've been having problems with it for some time now. The warnings are now handled, but I didn't go through the validation functions. You'll have to test those and see if they do what you intended.

Thanks for your help!

Thanks for your help!

The code in my last post has been edited so the 'undefined' warnings should be taken care of now . . .

@Pikachu2000

Thankyou for all your help and i understand fully you may have a busy schedule.

Im still faced with a few errors. I have managed to get the validation errors on screen, there were two missing & symbols. Everything works validation wise, but when i choose a value from the dropdown menu, the variable doesn't save and returns back to default, also when i upload an image to test validation, it always throws back the error.

Any ideas or recommendations?

I will post the code again with changes....

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1); ?>
<?php
function VerifyForm(&$values, &$errors) {
   // Do all necessary form verification
   // Validate Model Number
   if (strlen($values['model']) < 4) {
      $errors['model'] = 'Model Number too short';
   } elseif( strlen($values['model']) > 20) {
         $errors['model'] = 'Model Number too long';}
         // Validate Price
         if (is_numeric($values['price']) == 0){
            $errors['price'] = 'No Price has been entered';}
            // Validate Product
            if(($values['product']) == 0){
               $errors['product'] = 'No Product has been selected';}
               // Validate Image
               if ((($_FILES["photo"]["type"] != "image/gif")
               || ($_FILES["photo"]["type"] != "image/jpeg")
               || ($_FILES["photo"]["type"] != "image/pjpeg")
               && ($_FILES["photo"]["size"] > 2000000))) {
                  $errors['photo'] = 'Image format must be either JPG/JPEG/GIF or PNG';}
                  // Validate Description
                  if (strlen($values['description']) == 0){
                     $errors['description'] = 'Description is too short';}
                     return (count($errors) == 0);
}
