[SOLVED] Need help with echo error code

[nosher]

Dear All 

 

I am a complete beginner with PHP and would love some help with this issue if possible?

 

We had a calculator made for us by someone who has now left the country, so no way of contacting him.

 

Basically if nothing is entered into the filed it displays the error:

 

**You did not enter a Property Price. Please go back and try again**

 

If any letter is entered into the filed it makes a calculation, so what I would really like to be able to do is anything that is inputted into the filed other then numbers is shown the error code.

 

Is this at all possible? Am I missing something stupid here ?  :'(

 

This is the error code below

 

<?php

$error="The following errors occurred while processing your Quotation.<ul>";

if($electric==""){$errors=1;

$error.="<li>You did not enter a Property Price. Please go back and try again.<BR><BR>";}

if($errors==1) echo $error;

 

 

 

Any help with this issue would be greatly appreciated

$errors=1;
if($electric=="")
{$errors=1;
$error="<li>You did not enter a Property Price. Please go back and try again.<BR><BR>";
}
if($errors==1) 
{
echo $error;
}

If you want to display the entered value within the error message, try this:

 

$error_code = 0;
$error="The following errors occurred while processing your Quotation.<ul>";
if($electric=="") {
  $error_code=1;
  $error.="<li>You did not enter a Property Price.</li>";
}
elseif (!is_numeric($electric)) {
  $error_code=2;
  $error.="<li>You did not enter a numeric value ('$electric').</li>";
}

if($error_code) echo $error."</ul>\n"."Please go back and try again.<br>";

 

(don't forget to close the <ul> and <li> tags)

Thank you so Much

 

The following errors occurred while processing your Quotation. 
•	You did not enter a numeric value ('test').
Please go back and try again.

 

Now the error code is being displayed lovely, but a calculation is still being displayed under the error message is there anyway to stop the calculation being displayed

 

Just asking if this cant be done that’s fine

 

Many Thanks

The shortest way to modify your script would be like this:

 

if($error_code) {
  echo $error."</ul>\n"."Please go back and try again.<br>";
  // any page footer
  exit;
}

 

This terminates the script after any form validation error.

If you have a footer on your page, you might want to echo it before exit;-ing.
