PHP - Help With Validation Question

Hi, I have a mistmatched tag <messagesss></message> BUT it still displays "Validated XML!" BUT then proceeds to the else that outputs each XML error!

here is the XML:
Code: [Select]
<?xml version="1.0" encoding="utf-8"?>
<email>
<messagesss>
<to>
<toFirstName>Tove</toFirstName>
<toLastName toType="common" style="swag">Smith</toLastName>
</to>
<from><fromdd/>
<fromFirstName>Jani</fromFirstName>
<fromLastName fromType="unique">Dravison</fromLastName>
</from>
</message>
</email>

Code: [Select]
<?php
$dom=new DOMDocument();
$dom->load("emailSimple.xml");
$isValidated=false;
$dom->formatOutput = true;
$dom->saveXML();
$errors=libxml_get_errors();//Returns array where each XML file line is an elem
if(!file_exists("emailSimple.xml"))
print "no such file!";
else if(strlen(file_get_contents("emailSimple.xml"))==0)
print "File is empty!";
else if($dom) {//IF file exists and has content
if(empty($errors))
print "Validated XML!";//isValidated=true so now shred!
else
{
//CHECK if current XML file is Well-formed
foreach($errors AS $error) {//FOR EACH ERROR OF CURRENT XML FILE TO CHECK
echo "Error Code: ".$error->code."<br />";
echo "Error message: ".$error->message;

//Column is the end of the line where error is
echo "line".$error->line.", column".$error->column."<br />";

echo "----------------------------------------------<br /><br />";
}
}
libxml_clear_errors();
}
?>

i am using the following to validate a submission form.

when i take this validation script out, the php script works fine, however when i use it it redirects to index.html as if their was an error....

please can somebody help, ive tried and cannot see the problem?
$fname = $_POST['firstname'];
$lname = $_POST['lastname'];
$add1 = $_POST['add1'];
$add2 = $_POST['add2'];
$city = $_POST['city'];
$county = $_POST['county'];
$country = $_POST['country'];
$postcode = $_POST['postcode'];
$email1 = $_POST['email1'];
$email2 = $_POST['email2'];
$mobile = $_POST['mobile'];
$home = $_POST['home'];
$time = $_POST['time'];
$answer = $_POST['answer'];
$job = $_POST['job'];
$ip = $_SERVER['REMOTE_ADDR'];

// validation

$validationOK=true;
if (Trim($fname)=="") $validationOK=false;
if (Trim($lname)=="") $validationOK=false;
if (Trim($add1)=="") $validationOK=false;
if (Trim($city)=="") $validationOK=false;
if (Trim($county)=="") $validationOK=false;
if (Trim($country)=="") $validationOK=false;

if (Trim($time)=="") $validationOK=false;
if (Trim($answer)!=="34") $validationOK=false;
if (Trim($job)=="") $validationOK=false;
if (!$validationOK) {

  print "<meta http-equiv=\"refresh\" content=\"0;URL=index.html\">";

  exit;

}

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.
Spoiler

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> ";} 

Hi,

Im making a form that contains 3 textboxes.. now i want my textboxes to contain only letters..
i used is_numeric for the validation but when i put' like.. "JUSHIRO1" my code will still accept it.
 can someone help me make a code that will validate my textbox to only accept letters.
and one more.. when the user input in the textbox with a number a popup box will appear.

im looking to validate an email address before it gets sent to mysql database
currently my code checks if an email address is present and if an email address already exists
how do you check to see if an address contains a . and a @ symbol?
Code: [Select]
if($email == '') {
$errmsg_arr[] = 'Email is missing';
$errflag = true;
}

if($email != '') {
$qry = "SELECT * FROM users WHERE email='$email'";
$result = mysql_query($qry);
if($result) {
if(mysql_num_rows($result) > 0) {
$errmsg_arr[] = 'Email address already in use';
$errflag = true;
}
@mysql_free_result($result);
}
else {
die("Query failed");
}
}

Thanks in advance

Chaps, as a beginner developing his first web app in PHP, I have done fairly well.   However, I am struggling when it comes to validation.   I have written different ELSEIF statements as seen below which would actually carry out the validation itself.

// First name must be filled and in correct format.

if(empty($FirstName)) {
    $errFirstName = '<p class="errText"> Please enter a value</p>';
    echo $errFirstName;
}elseif(!preg_match('/^[a-z]+$/i',$FirstName)){
    $errFirstName = '<p class="errText">Name may not start with a dash. Letters, spaces and dashes are accepted.</p>';
    echo $errFirstName;
}

The problem is that I do not know how to make them "pop up" when the user makes a mistake.   I have a form in addteam.php seen below:

<form action="pushteam.php" method="post">
            <p>Team name: <input type="text" name="TeamName" /></p>
            <p>Description: </p>
            <p><textarea name="Description" rows="4" cols="50">Add your description here.</textarea></p>
            <p><input type="submit"/></p>
          </form>

And a pushplayer.php script that pushes it to a mysql database:

// Get values from form
  $TeamName=$_POST['TeamName'];
  $Description=$_POST['Description'];


  }

  // Insert data into database
  $sql="INSERT INTO Teams(TeamName, Description)VALUES('$TeamName', '$Description')";
  $result=mysql_query($sql);

  //If successful return to success.php else print error
  if($result){
    header( 'Location: success.php');
  }

  else {
    header( 'Location: failure.php');
  }

The scripts function properly. I would really appreciate if someone could guide me in the right direction here. Make the error pop up and make sure the data is not input. At the moment, if I add my ELSEIF statements, it will carry on and insert the data anyway and redirect me. Thanks

I am really new to using php validation, I think I may be on to what I am looking for but not very sure. I am trying to validate my form fields just incase someone forgets (name, subject, message, and email).  Here is what I have so far. I was looking at an example on how to validate a phone number.

Any help on this would be great!

I have a form validation script which is written in php..

I want to add a validation (in registration form) that if the desired username contains either admin or owner keyword user will have to change his user name..

I made the following code but it does not work..

if(strpos($user_name, "admin")>=0 || strpos($user_name, "moderator")>=0 || strpos($user_name, "owner")>=0)
{
$error=$error."You are not allowed to take such Username<br>";
   $bool=false;

}


In this code i am not able to enter any username..

And if i change >= to > then "admin123" username is going to be valid...

I am troubled .... help me out guyzzz

Hi there,

I am working on getting my php form validation working. I just learned why mine wasn't working and it was because I had a header(location) in the middle of the html doc. The reason I had it there was because the code I am using is placed where I want the error to show. Here is the code I am using for this part. I only have one field being validated at the moment.

Code: [Select]
<?
session_start();

  if ($_POST['submit']) {
 
  $_SESSION['City'] = $_POST['City'];
 
  $errors = "";
 
  if(!$_SESSION['City']){
  $errors = $errors . "Please enter your city<br>";
  }
  if ($errors != "") {
  echo "Please check the following errors:<br>";
  echo $errors;
  }
  else {
  header("Location: nextpage.php");
  }
  }

?>
My question is:
What way would you reorganize this (scrapy) validation to where I can redirect my user to a new page when there is no error value?

The form page submits to itself with POST.

Thanks for your help.

So Im in the weird place where my age validation is not working, any ideas:

$dob = strtotime($_POST['dob']); //855993600 Feb 15th 1997
$age_req = strtotime('-13 year', $dob); //445680000 Feb 15th 1984
$time = time(); //1292007621

if ($time < $age_req){}

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

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!
