Email Contact Form

Hiya,

Using PHP, how do you check multiple fields to ensure the correct information (if any) has been entered, and if not, change the label text and textbox border colour to red, and list the errors as bullet points.

The following fields need to be checked for the following:

• Name - Not Blank, Contains A-Z only.
• Email - Not Blank, Correct Format.
• Phone- Not Blank, Contains 0-9 only.
• Type - Must be selected.
• Location - Must be selected

<form name="form1" method="post" action=""><label>Name:</label>
  <input name="name" type="text" id="name">
  <br>
  <br>
  <label>Email:</label>
  <input name="email" type="text" id="email">
  <br>
  <br>
  <label>Phone:</label>
  <input name="phone" type="text" id="phone">
  <br>
  <br>
  <label>Mobile:</label>
  <input name="mobile" type="text" id="mobile">
  <br>
  <br>
  <label>Type:</label>
  <select name="type" id="type">
    <option>Type 1</option>
    <option>Type 2</option>
    <option>Type 3</option>
  </select>
  <br>
  <br>
  <label>Location:</label>
  <select name="location" id="location">
    <option>Location 1</option>
    <option>Location 2</option>
    <option>Location 3</option>
  </select>
  <br>
  <br>
  <input type="submit" name="Submit" value="Submit">
</form>

Code (markup):

 

it's a long code

 

just use if else. when the user submit.
<?
if(isset($_POST['Submit'])){
$name = $_POST['name'];

if(strlen($name)<=0){
echo "Enter name";
}
}
?>
btw you can also use javascript to do this form validation
