The html file linked with php validation file
<!DOCTYPE html>
<html>
<body>
<form action="a6.php" method="post">
<label for="email"> Please enter your email address:
<input type="text" name="email" id="email" data-validation="email">
<!-- Display validation message for email input -->
<?php the_validation_message('email'); ?>
</label>
<fieldset>
<legend> Please select your three favorite animals:</legend>
<input type="checkbox" name="animals[]" id="chicken" value="chicken" data-validation="checkbox_group" data-
validation-qty="min3">
<label for="chicken">Chicken</label>
<input type="checkbox" name="animals[]" id="cow" value="cow" data-validation="checkbox_group" data-
validation-qty="min3">
<label for="cow">cow</label>
<input type="checkbox" name="animals[]" id="whale" value="whale" data-validation="checkbox_group" data-
validation-qty="min3">
<label for="whale">whale</label>

<input type="checkbox" name="animals[]" id="kitten" value="kitten" data-validation="checkbox_group" data-
validation-qty="min3">
<label for="kitten">kitten</label>
<input type="checkbox" name="animals[]" id="jellyfish" value="jellyfish" data-validation="checkbox_group" data-
validation-qty="min3">
<label for="jellyfish">jellyfish</label>
</fieldset>
<label for="date"> Please enter your favorite date: (yyyy/mm/dd)
<input type="text" name="date" id="date" data-validation="date" data-validation-format="yyyy/mm/dd">
<!-- Display validation message for date input -->
<?php the_validation_message("date"); ?>
</label>
<input type="reset" name="" value="Reset Form">
<input type="submit" value="Submit Form">
</form>
</body>
</html>
The php validation file:
<?php
// Global result of form validation
$valid = false;
// Global array of validation messages. For valid fields, message is ""
$val_messages = Array();
// Check each field to make sure submitted data is valid. If no boxes are checked, isset() will return false
function validate()
{
global $valid;
global $val_messages;
array_push($val_messages, "email is not correct format", "please enter a valid date in the format yyyy/mm/dd",
"please choose atleast three animals",""
);
if($_SERVER['REQUEST_METHOD']== 'POST')
{
// Use these patterns to check email and date, or come up with your own.
// email: '#^(.+)@([^\.].*)\.([a-z]{2,})$#'
// date: '#^\d{4}/((0[1-9])|(1[0-2]))/((0[1-9])|([12][0-9])|(3[01]))$#'
if(isset($_POST['email']) == true && isset($_POST['date']) == true && isset($_POST['animals']) == true){
if(!preg_match('#^(.+)@([^\.].*)\.([a-z]{2,})$#', 'email')){
return $valid;
} else if(!preg_match('#^\d{4}/((0[1-9])|(1[0-2]))/((0[1-9])|([12][0-9])|(3[01]))$#', 'date')){
return $valid;
} else{
$valid = true;
}
/*for($i=0;$i<count($_POST['animals']);$i++){
}*/
}
}
}
?>
Thanks for suggesting this way
