Do die statements and echos display differently?

[wright67uk]

I have a problem with formating the appearance of a die statement.

As you will see from the css below, p.form and p.passed both have the same text-align, and marginal values,

however they display very differently.  P.passed is used in an echo, and P.form is used in a die.

I want to display both my echo and die statements in the same place.  Ive tried the obvious and played around with the margins on P.form but it doesnt seem to make any difference.  I can only presume that my die statement is ignoring the class im assigning it?

 

P.form

{

color:#FF03;

margin-left:100px;

text-align:left;

clear:both;

}

P.passed

{

color:#333;

margin-left:100px;

text-align:left;

clear:both;

}

 

<?php // snippet

if($Name == '')
{
	die ("<P class=\"form\">You did not complete the name field, please try again</p>");
}
elseif  ($Phone == '' or (preg_match("/^([1]-)?[0-9]{3}-[0-9]{3}-[0-9]{4}$/i", $Phone)))
{	
	die('<P class="form"> You completed the telephone field incorrectly, please try again</p>');
}		
elseif  ($Email == '' or (!filter_var($Email, FILTER_VALIDATE_EMAIL)))
{
	die('<P class="form"> You completed the Email field incorrectly, please try again</p>');
}									   
elseif  ($Postcode == '' or (!checkPostcode($Postcode)))
{
	die('<P class="form"> You did not complete the Postcode field correctly, please try again</p>');
}		  
elseif  ($Website == '' or (!preg_match("~^[a-z0-9.-]+\.(com|org|net|edu|co.uk)~i", $Website)))
{   																									
	die('<P class="form">You completed the website field incorrectly, please try again</p>');
}
else
{
	echo("<P class=\"passed\">Thankyou for submiting your details, you will be added to our directory shortly</p>");
}}

 

Ive formatted if and else slightly differently but the output is still the same.

Should die statements and echo's display differently?

[trq]

die() outputs a string ands halts the script, echo outputs a string. Essentially they are the same.

Killing the script for each instance where the user hasn't filled in the form correctly is bad application design.

 

You should instead add your error messages into an array when your validation for whaterver field fails, example for the Name field

	if($Name == '')
{
	$errors[] = '<P class="form">Name field left empty</p>';
}

 

When you have finished validating the user input you can check whether any errors have accrued. if there are errors then display them, along with the form. If there are no errors then display your success message.

if(!empty($errors))
{
    echo 'Sorry correct the following errors: <ul><li>' . implode('</li><li>', $errors);
    // display your form here
}
else
{
    echo("<P class=\"passed\">Thankyou for submiting your details, you will be added to our directory shortly</p>");
