PHP - Automatic Validation Of Form With Php

Hi,

I currently have the following code in my form processing script:

Code: [Select]
    $string_exp = "/^[A-Za-z .'-]+$/";
$error_missing = 'This field is required';
 
    if(!preg_match($string_exp,$Name)) {
    $errors[] = $error_missing;
  }
   
  if(!preg_match($string_exp_number,$Phone)) {
    $errors[] = $error_missing;
  }
   
    if(is_array($errors))
{
echo 'Your message could not be sent due to the following errors:';
while (list($key,$value) = each($errors))
{

echo '<span class="error">'.$value.'</span><br />';
}
If the user enters no data into the required fields, the script prevents the form from being submitted and displays an error.

At present the errors for all the required fields are displayed in a long list at the top of my HTML form e.g.

This field is required
This field is required

What I want to do, is place the error message under each required field e.g. this http://coreyworrell.com/assets/uploads/images/ajax_contact_form.png instead of this http://cdn1.1stwebdesigner.com/wp-content/uploads/2010/02/validation-ajax-css-form.jpg

What do I need to do?

My form looks similar to this at the moment:

Code: [Select]
<div id="log">
<div id="log_res">
</div>
</div>
<form id="contact" name="contact" method="post" action="process.php">
  <label>Name</label>
    <input type="text" name="Name" id="Name" tabindex="1" />
 
  <label>Email</label>
    <input type="text" name="Phone" id="Phone" tabindex="2" />
</form>
The error messages are placed in the <div> section at the top of the form (using ajax)

I have a pretty complicated script i'm trying to work on but i'm not having much luck.  Basically what needs to happen is i need part of my script to check a database and count 2 different sets of data for the current date, then if both conditions are true then submit the users name, current date, and a time id to the database it checks, and then submit the form data to a text file.  i'll try and map it out.

check database for how many times the username appears for current date
if it is less than 3 move to next validation
if it is false, give error message

check database for how many times the time id appears for current date
if it is less than 30 move to next section
if it is false, give error message

send username, timestamp (of clients computer),  and time id to the 'totals' database
and
send form data to text file.


So.... thats it in a nutshell.  I'm going to have to go into my 'cart' page and edit in a row to have the order#, username, timestamp, and time id before the rest of the order details

I want in my form to validate on the fly(when the user enters the user name) to validate if the user name exists or not. How am i supposed to check if the field name is the same or not with a name in the database.Should i use ajax or javascript? is there any simple example on how to do that.

I'm trying to get validation messages to display on the same page as my login form without any PHP within my login page, is that possible? 

Hi there,

I've got a HTML textarea with the name attribute of 'review' and I've posted this into a variable called $review.
I want to say if the characters are less than 30, please enter more words etc.

The problem is, I get the if statement's error even when there are more than 30 characters.

Can anyone figure out why I'm getting this?
Code: [Select]
if ($review < 30){
echo '<p class="red">Review is too short, please enter at least 15 words</p>';
}

Hello All,

I am a newbie to PHP and I'm working on a marathon sign up form for my final project and could really use the help. The trouble i'm having is sending and retrieving database from the database. Below is the code i am using. Can someone please review and tell me where I went wrong.

 

(This is the code that is sitting at the top of my document)

<?php
session_start();
require_once('inc/dbuser.php');
function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}
if (isset($_POST['submit_registration'])) {
$username = test_input($_POST['username']);
$password = test_input($_POST['password']);
$cpassword = test_input($_POST['cpassword']);
$fname = test_input($_POST['fname']);
$lname = test_input($_POST['lname']);
$email = test_input($_POST['email']);
$phone = test_input($_POST['phone']);
$address = test_input($_POST['address']);
$city = test_input($_POST['city']);
$state = test_input($_POST['state']);
$zip = test_input($_POST['zip']);
$distance = test_input($_POST['distance']);
if (!empty($username) || !empty($password) || !empty($fname) || !empty($lname)|| !empty($email) || !empty($phone)|| !empty($address)|| !empty($city)|| !empty($state)|| !empty($zip)|| !empty($distance)) {

}
else{
    
     $sql = "SELECT email From runners Where email = ? Limit 1";
     //Prepare statement
     $stmt = mysqli_stmt_init($conn);
     if(!mysqli_stmt_prepare($stmt, $sql)){
       header("location: ../signup?error=sqlerror");
      exit();  
     }
     else{
     mysqli_stmt_bind_param($stmt,'s', $email);
     mysqli_stmt_execute($stmt);
     $stmt->bind_result($email);
     $stmt->store_result($stmt);
     $resultCheck = mysqli_stmt_num_rows($stmt);
     if ($resultsCheck > 0) {
      header ("Location: ../signup.php?error=usertaken&email=".$email);
      exit();
     }
     else {
         $sql = "INSERT Into runners (username, password, fname, lname, email, phone, address, city, state, zip, distance) values(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)";
         $stmt = mysqli_stmt_init($conn);
         if(!mysqli_stmt_prepare($stmt, $sql)) {
             header ("Location: ../signup.php?error=sqlerror");
      exit();
         }
         else{
            $hashedPwd = password_hash($password, PASSWORD_DEFAULT);
         mysqli_stmt_bind_param($stmt,"ssssssssssss", $username, $hashedPwd, $fname, $lname, $email, $phone, $address,$city, $state, $zip, $distance);
         mysqli_stmt_execute($stmt);
         header ("Location: ../signup.php?signup=success");

 }
}
     }    
}

     mysqli_stmt_close($conn);

How can I go about validating a form in PHP? I am trying to do so, but I am clueless as to how to structure it.

Hi Guys, Im a bit of a novice to Php but somehow I've managed to get myself a form together for customers to book online. My problem is that i need to validate all the input's of my form. To give you some idea of what i mean. The $name should only contain letters and be no longer than 25 characters. The $address should only contain letters & numbers and be no longer than 40 characters. The $district and $town should only contain letters and be no longer than 30 characters each. The $postcode should only contain letters and Numbers and be no longer than 8 characters, it should start and end with a letter if thats possible. The $phone should only contain numbers and be no longer than 11 characters. And the email, well im lost with how that should be set out because of all the different options you can have.
Anyway, this is my code:

<?php $to = 'myemail.com' ;
                   $from = $_REQUEST['Email'] ;
                   $name = $_REQUEST['Name'] ;
                   $phone = $_REQUEST['Phone'];
                   $headers = "From: $from";
                   $subject = "Booking Request";
                   $fields = array();
                   $fields{"Name"} = "Name";
                   $fields{"Address"} = "Address";
                   $fields{"District"} = "District";
                   $fields{"Town"} = "Town";
                   $fields{"Postcode"} = "Postcode";
                   $fields{"Phone"} = "Phone";
                   $fields{"Email"} = "Email";
                   $fields{"list"} = "Mailing List";
                   $fields{"Message"} = "Message";
                   $body = "We have received the following information:\n\n"; foreach($fields as $a => $b)
                   {         $body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]); }



                        if ($name == '') {print "You have not entered a name, please go back and try again";}
                        elseif ($phone == '') {print "You have not entered a Phone number, please go back and try again";}


                        else { $send = mail($to, $subject, $body, $headers);

                        if($send) {header( "Location: http://www.(not applicable).com" );}
                        else {print "We encountered an error sending your mail, please notify webmaster@YourCompany.com";  } } ?>

Any help is greatly apprecaited.

Kind regards

Hi,

I am trying to setup a PHP script that will validate an html form. The form and the PHP script are separate from each other. The code that I have was modified from a tutorial on YouTube. The example used there works but as I have began to tailor it to my purpose, it is now broke. I just added one line for validation to simplify troubleshooting. If I find an empty field on the form, I would like to display the error message on the form itself rather than start a new html page with the PHP script. I am not sure if that is possible.

Here is my form:
http://www.tallfirshoa.com/adform.htm

YouTube videos that I was working from. The video's example has the form and PHP combined as one. In my case, I need the form and PHP separate.
http://www.youtube.com/watch?v=yuLpSospbBk&feature=search
http://www.youtube.com/watch?v=LF5zTWthpn0&feature=search

The code works fine if I leave out the validation. As soon as I add if(!$fname), the script becomes broken. I'm guessing that it has something to do with $errorstring and how it works. I am new to PHP and have tried as many things as I can think of but I can't make any forward progress.

Thanks for your help!

Hi. I'm new to PHP and have a problem with some form validation.

The code below is my contact form. It was working until I added a dropdown list and checkbox. For all the other fields I created an input variable using the 'name' attribute to reference the data entered into the input fields and the validation appeared to work and an email was sent to the appropriate email address.

For the checkbox field I have also created a 'name' attribute but don't know whether this is right way to confirm whether the box has been checked?

For the field with a dropdown selection I have used the option 'selected', but again, don't know whether this is right or not.

Now when I enter valid data into all the fields, select a value from the dropdown and check the checkbox, I get an error message stating that I need to fill in all the form fields. I am pretty sure it is to do with the way I have tried to pick up the data from dropdown list and the checkbox, but can't figure out what it is. 

Any help would be much appreciated.

Thanks in advance.

Hi

I am currently writing code to validate a form using PHP. What i wanted was to validate all inputs and then post the data to a external mysql server.

However, i want a function placed on the submit/send button of the form, in which the function checks to see if there are no errors and then forwards the user to another page where the data is inserted into the sql database.

Here is what i have so far:

add_test.php

Code: [Select]
<?php
include("validation.php");
?>

any suggestions on how to write the code for the send button? Im abit stuck and being a newbie dont help lol.

Hello!

I was wondering if I could  have some help with some form validation.  In my insert script, I have:

<label for="text"><br />
          <br />
         Question Text:</label>
        <textarea name="text" id="text" cols="45" rows="5">
     </textarea>

Then in a separate script, I input the data into a database:

$data = array('text' => $_POST['text']

  'question_type' => $_POST['question_type'],

  'solution' => $_POST['solution'],

  'author_id' => $_POST['author'],

  'public_access' => $_POST['public_access']);

In this database script, I'd like to check if the text field was "posted":  if it's empty I'd then like to print "Required field" on my original script.

First, if there's nothing to be posted from the text field, I want to stop the database script and return before entering a blank field into my database.  Then, it would be great if I could print a "Required field" message in the original script. Thanks in advance for your help!

Okay with some help I was able to create a working guestbook!

How ever I need a bit of help with validation.

I would like to have it so that when someone doesn't fill out a required field a message is displayed next to the improperly filled out field. How would I go about adding this to my form or process code?

So for example:

if someone doesn't fill out the "name" field and clicks "sign" it will not submit but instead will display a message such as "Please fill out your name" next to the form field.

Also will I am here I wanted to ask. How can I make it so that when a non-required field is left empty and posted it will fill that section out with default text?

So for example:

if someone decides they do not wish to fill out the "Favorite part of my site" or "Favorite Pat Song" field than submits the form than it will fill that section with a default message

like this:

Posted by: someone  (someone@domain.com)
2011/04/09
Favorite Pat Song: --
Favorite Part of the Site: --
comments here

And I promise this is my very last question. I would like for email to be required but would like to allow the user to decide whether it is kept private or not. How do I make it so that when someone doesn't type their email in it does like what I stated above, it will show a message next to the field telling them to fill out a valid email but also if they select to keep their email private it will than post a default value in place of where the email would have been.

for example:

if the email field is left empty or is an invalid email it will display a message such as "Please fill out a valid email address" next to the form field.

and than if they do so but also check the "private" box it will post their message in the guestbook with a default value in place of the email like this:

Posted by: someone  (Private)
2011/04/09
Favorite Pat Song: --
Favorite Part of the Site: --
comments here

so that was a lot

here's my guestbook code:

and here's the code that processes the form (separate file):

Code: [Select]
<?php

if($_POST['submit']) {

$connect = mysql_connect('127.0.0.1','patben_admin','pepsi_1990') or die('Error connecting');
$db = mysql_select_db('patben_db')  or die('Error selecting db');

$date = date("Y-m-d");
$name = strip_tags($_POST['name']);
$email = strip_tags($_POST['email']);
$song = strip_tags($_POST['song']);
$part = strip_tags($_POST['part']);
$comments = nl2br($_POST['comments']);


$query = mysql_query("insert into guestbook values('','$date','$name','$email','$song','$part','$comments')");

header("location: guestbook.php");

}else{

header("location: guestbook.php");

}

?>
I have not added a section in my database for the check box so I am also unsure how to do that (if I need to). Any help would be greatly appreciated!

Thank you
