    Validation

    in PHP Coding Help

    Posted · Edited by aub

    I need to validate first name, last name, street, suburb, postcode, email, status and date of birth. 
     

    I tried to do this validation but gave me heaps of error and I messed up more.

     

    if (empty($firstname)) {$errors[] =" First Name Can not be Empty <br> ";}
if (empty($lastname)) {$errors[] =" Last Name Can not be Empty <br> ";}
if (empty($street)) {$errors[] =" Street Can not be Empty <br> ";}
if (empty($suburb)) {$errors[] =" Suburb Can not be Empty <br> ";}
if (empty($postcode)) {$errors[] =" Postcode Can not be Empty <br> ";}
//    elseif (!is_numeric($postcode)) {$errors[] =" Postcode must be numeric ";}
    elseif(!preg_match("/\^\(\[0\-9\]\{5\}\(\[\-\\s\]\?\[0\-9\]\{4\}\)\?\)\$/", $postcode))  {$errors[] =" Please enter a valid post number <br> ";}
if( !preg_match("/^[_a-z0-9-]+(.[_a-z0-9-]+)*@[a-z0-9-]+(.[a-z0-9-]+)*(.[a-z]{2,3})$/i", $myemail) )  {$errors[] =" You have entered and invalid email address <br> ";}
if (empty($DOB)) {$errors[] =" Date only <br> ";}

     

     

     

     

    This is my full PHP/MySQL code:

    Design a form that accept your first name, last name and email address. Use GET for posting the form into the same php page, print out the result:

    (first_name, last_name, and email_address after the form is being submitted, you must validate your first_name, last_name are alphabetic, and your email address is valid. Also all fields must be mandatory. 

    I don't know how to make first name and last name alphabetic and email address valid. 

    This is my code:
     

    <html xmlns='http://www.w3.org/1999/xhtml'>
	<head>
		<meta http-equiv='Content-Type' content='text/html; charset=utf-8'/>

	</head>

<h1>TASK 3: Question 4</h1>

<?php 

if (isset($_GET['Submit'])) {
	echo "inside the form". $_GET['Submit'] . "<br>";

$firstname = $_GET['fname'];
$lastname = $_GET['lname'];
$DOB = $_GET['dob'];


if(empty($_GET['fname']) || empty($_GET['lname']) || empty($_GET['dob'])) {
    echo 'Please fill in all of the fields.';
} else {
    $firstname = $_GET['fname'];
    $lastname = $_GET['lname'];
    $dob = $_GET['dob'];
    if(ucfirst($firstname) != $firstname || ucfirst($lastname) != $lastname) {
      echo 'The first letter of your first and last name must be in upper case.';
    } else {
      echo 'Thank you ' . htmlspecialchars($firstname) . ' ' . htmlspecialchars($lastname) . ', for entering your date of birth: ' . htmlspecialchars($dob) . '<br />';
    }
} 
		
} else {

?>

<form action="getform.php", method="get">

    [TINY HELP] in_array

    in PHP Coding Help

    Posted

    Hi guys, just need your tiny help. I'm learning as you can see.

    The question says: 
    Create a script to check if the value "Sydney" is stored in the following array (hint: use function: in_array) 
    $cities = array("New York", "London", "Sydney", "Paris", "Brisbane")
    (Note: you must print the ending result)

     

    This is my code:

    <?php
$cities = array("New York", "London", "Sydney", "Paris", "Brisbane")
if (in_array("Sydney", $cities)) {
echo "Yes, Sydney is stored!";
}
?>

    I cant fix the problem? 

    Your help would be lovely.

    Thanks! 

    Can you test this for me please?

    For some reason, when I click the button "Submitted", the error came up "Object not found!" but I believe my php still works?

    in PHP Coding Help

    Posted · Edited by Ch0cu3r

    Hi guys, this is my very first post and thread as you can see. At TAFE, I'm doing Certificate IV and we started learning how to code in php. It's pretty fun, to be honest! :)

    I have 3 questions and I just need your help if you don't mind or if you're bored/free. 
    _____________________________________________________________

    Having the following students table:
    mt3O0kH.png

    1. Convert the table into an array (Linear array)
    2. Convert the array into associative array
    3. Use list function to print the SID, and NAME, i.e key and value

    _____________________________________________________________

     

    Your help would be greatly appreciated! 

    Thanks.
