Form Validation Help please

[Blargh]

I have a form that looks like this...

• Company Name:
• Name:
  
  Title:
• E-mail Address:
• Confirm E-mail Address: .
• Phone Number: () -
  Type of Business: <drop down>
  Number of Employees:
  
  Number of Locations:
  
  Location Sites: <drop down>

Basically, using php, how could I get validation that the names (both company and name) have not been left blank... validation that the phone number is all digits.... and validation as to the e-mail being legit and matching with the other.

Any and all help will be greatly appreciated.

you can either use javascript to detect it before the form is submitted or for more securoty do that as well as validation after the form is submitted and return them to thispage if something is wrong and tell them.

do u have any code yet? if so post it..

lets say the variable for Company Name is $CoName and the variable for Name is $Name. THe Email is $Email and Confirm Email is $CoEmail you could use an if statement to check if they are full i.e.

if($CoName != "" && $Name != "" || $Email !== $CoEmail )
{ echo "Error!!";
}
elseif
{ //continue on with code
}

that might give u a start... im at work so i dont have much time to test it but i can help ou more later if u giveme som feedback..
