Validation Issue	View Content

Having a validation issue when a person enters a - in there name it is kicking it back as invalid.

For axample:

Mary-Ann Invalid
Mary Ann Valid

Tried including the - but causing myself a lot of grief.

function filterkudoagent($field){
    // Sanitize user name
    $field = filter_var(trim($field), FILTER_SANITIZE_STRING);

    // Validate user name
    if(filter_var($field, FILTER_VALIDATE_REGEXP, array("options"=>array("regexp"=>"/^[a-zA-Z\s]+$/")))){
        return $field;
    } else {
        return FALSE;
    }
}

I want to submit data of my student registration form to the database. If an admission number already exists, a message should be displayed like this.

"Admission number2012/1..This student has been already entered to the system."

I have created the below coding which fulfill the above task. But i want slight modification, rather than displaying the message in a seperate field after entering all the fields i want the message to display soon after entering the "Admission Number" in my form.

newStudentRegistrationFormValidation.php

Code: [Select]
<?php
$admission_no=$_POST['admission_no'];
$admission_date=$_POST['admission_date'];
$full_name=$_POST['full_name'];
$name_with_initial=$_POST['name_with_initial'];
$date_of_birth=$_POST['date_of_birth'];
$religion=$_POST['religion'];
//$gender=$_POST['gender'];
$address=$_POST['address'];
$telephone=$_POST['telephone'];
$grade_on_admission=$_POST['grade_on_admission'];
$grade_ID=$_POST['grade_ID'];
$stream_ID=isset($_POST['stream_ID']);
$class_ID=$_POST['class_ID'];
$student_house=$_POST['student_house'];
$password=$_POST['password'];
$description_about_st=$_POST['description_about_st'];
$payment=$_POST["payment"];

$currentdate=getdate(time());
$year=$currentdate["year"];

//admission number validation

$con=mysql_connect("localhost","root","");
mysql_select_db("student_management",$con);

$query="SELECT admission_no FROM student_info Where student_info.admission_no='$admission_no'";
$result=mysql_query($query) ;
$num_rows = mysql_num_rows($result);
echo $num_rows;

if($num_rows >= 0)
{

header("location:student registrationDatabase.php?admission_no=".urlencode($admission_no)."&year=".urlencode($year)."&admission_date=".urlencode($admission_date)."&full_name=".urlencode($full_name)."&name_with_initial=".urlencode($name_with_initial)."&date_of_birth=".urlencode($date_of_birth)."&religion=".urlencode($religion)."&address=".urlencode($address)."&telephone=".urlencode($telephone)."&grade_on_admission=".urlencode($grade_on_admission)."&grade_ID=".urlencode($grade_ID)."&stream_ID=".urlencode($stream_ID)."&class_ID=".urlencode($class_ID)."&student_house=".urlencode($student_house)."&password=".urlencode($password)."&description_about_st=".urlencode($description_about_st)."&payment=".urlencode($payment));
exit();

}else{

?>

<?php
echo "Admission number".$admission_no." .This student has been already entered to the system ."."<BR>"."<BR>"."<BR>";
echo "<a href='newStudentRegistrationForm.php'>GO to manage student details page</a> ";

Logic Issue? Email Validation

Similar Tutorials

View Content

Hey all, trying to figure out a logic flaw in this validation script. Basically if I use !preg_match or the preg_match examples (noted below), I do not get the correct results. My interpretation of preg_match and my current understanding of the logic is noted below (please correct me if I'm wrong). 1. If I use alternate attempt !preg_match, the regex would be compared against the "string" in the $email variable. If the regex expression matches, error will be thrown and script would stop. 2. If I use alternate attempt !preg_match, the condition would be not true and move to else where the string contained within $email variable would be run through the vld function. 3. If I maintain the current script using preg_match, if the string matches the match, the condition would be true and therefore string of $email variable runs through VLD function else cleanup and throw error... Are my statements above correct in this context? I think I'm pretty close to cracking it but seem to be missing something simple. The current script is referenced below, forgive me if I've lost the plot. Long hours attempting to understand this language, from what I've seen so far its great. Thanks in advance, A //Alternate attempt if (!preg_match("/^[^@]+@[^@.]+\.[^@]*\w\w/", $email)) {
                                    $error = "Please enter a valid email address"; } else {                                     $email = vld($_POST['email']);
                                  } Current code that doens't work: if (empty($_POST['email'])) {
    $error = "Email is required"; } else {
       if (strlen($_POST['email']) < 5) {
           $error = "Email is too short!"; } else {
              if (strlen($_POST['email']) > 30) {
                  $error = "Email is too long!"; } else {
                      if (preg_match("/[\<\>\,\;\:\\\"\[\]]/", $email)) {
                          $error = "The email address contains illegal characters"; } else {
                              if (preg_match("/^[^@]+@[^@.]+\.[^@]*\w\w/", $email)) {
                                  $email = vld($_POST['email']); } else {
                                      $error = "Please enter a valid email address";
                                  }

Was This A Php Issue Or An Html5 Drop Down Issue ?

Similar Tutorials

View Content

Folks,

I remember once having a php or html5 issue where the first option had to be blank in the drop down. Otherwise, it wasn't working.

What wasn't working ? How wasn't working ? I can't remember. either php had difficulty reading user input or the drop down was not showing any options. And so, I had to add a blank value.

So, something like this wasn't working ...

	<label for="tos_agreement">Agree to TOS or not ?</label>
<select name="tos_agreement" id="tos_agreement">
<option value="yes">Yes</option>
<option value="no">No</option>
</select>

And, I think I added a blank value, at somebody's advice, to get it to work. I think it was something like this, if I remember correctly:

	<label for="tos_agreement">Agree to TOS or not ?</label>
<select name="tos_agreement" id="tos_agreement">
	<option value=" ">Select here</option>
<option value="yes">Yes</option>
<option value="no">No</option>
</select>

Or, maybe it was something like this:

	<label for="tos_agreement">Agree to TOS or not ?</label>
<select name="tos_agreement" id="tos_agreement">
	<option value=" "></option>
<option value="yes">Yes</option>
<option value="no">No</option>
</select>

I can't remember. All I remember slightly that there was a blank value.

I been going through my php files to find that particular file to jog my memory but I failed to find it.

Can you folks explain to me if a blank value is required or not ? What is the benefit/disaster of adding it and how should the blank value be added ? Show me an example.

Was this a php or html 5 issue ? Can anybody fugure ?

Thank You

Hi, I have this code below which groups all the SubHeading together and then queries the same table to find RiskConsequence which are grouped that match SubHeading then to query this table one more last time with all the Risk Mitigation that matches the grouped RiskConsequence.

Problem I get is it does the SubHeading, the RiskConsequences it only does one of them not all of them before it moves onto the RiskMitigation.

I know I have a php coding issue just cant see the wood from the tree's as the queries work.

Code: [Select]
<?php
include ("include.php");
$query = "SELECT * FROM tblriskassessmentdatabank GROUP BY SubHeading";
$results = mysql_query($query) or die("Error: " . mysql_error());
while($row1 = mysql_fetch_array($results)){


    echo'<a href="#" onClick="return(changeDisplay(';echo"'";echo($row1[SubHeading]);echo"'))";echo'">';echo($row1[SubHeading]);echo'</a><br /><br />';
echo'<div id="';echo($row1[SubHeading]); echo'" class="HideText">';

$risksub = $row1[SubHeading];

$query1 = "SELECT * FROM tblriskassessmentdatabank GROUP By RiskConsequence";
$results1 = mysql_query($query1) or die("Error: " . mysql_error());
while($row2 = mysql_fetch_array($results1)){

echo'<a href="#" onClick="return(changeDisplay(';echo"'";echo($row2[RiskConsequence]);echo"'))";echo'">';echo($row2[RiskConsequence]);echo'</a><br />';
echo'<div id="';echo($row2[RiskConsequence]); echo'" class="HideText">';
$risksub1 = $row2[RiskConsequence];
$query1 = "SELECT * FROM tblriskassessmentdatabank WHERE RiskConsequence = '$risksub1'";
$results1 = mysql_query($query1) or die("Error: " . mysql_error());
while($row3 = mysql_fetch_array($results1)){

echo'<input name="checkbox[]" type="checkbox" id="checkbox[]" value="';echo($row3[IssueNumber]);echo'" />
    <label for="checkbox[]"></label>';echo($row3[RiskMitigation]);echo'<br /><br />';

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.

Code: [Select]

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<?php

$first_name=$_POST['name'];
$email_address=$_POST['email'];
$subject=$_POST['subject'];
$message=$_POST['text'];

  if(isset($_GET['submit'])) {
          if(preg_match("/^\(([
                                  $_GET['email']) != ) {
               echo "The email field was invalid<BR>";
          }

  else if(isset($_GET['submit'])) {
          if(preg_match("/^\(([

}
else if(isset($_GET['submit'])) {
          if(preg_match("/^\(([

               echo "The subject field was invalid<BR>";
     } else {

mail("myemailaddress@gmail.com","Subject: $subject",

echo "Thank you for using our mail form.<br/>";
echo "Your email has been sent.";

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

Php Validation

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

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.

I am a newbie to php. Ran away from it from years but now I see the light!

I am in the process of developing a web site application w/ MySql backend and I would like to do the following:

1. Client registers for my site.
2. How do I create code that validates password format to meet my password criteria (i.e. (2) capital letters, (2) special characters etc etc.

Password Validation.

Hi, I am trying to set up a useername / password validation log in for a website - code below.

I'm fairly new to php, so my understanding of what I have done is:

config and env pick up some basic info including the servername, username, password and dbname for the connection, $_POST["username"] and $_POST["pwd"] are the values entered by the user on a previous log in page. Users is queried to bring back the data in $sql where the posted username ($userid) matches the UserName in the table. This is then checked to ensure there is one row returned - if not we go to test3.php If there is one row, the password entered on the log in ['pwd'] is compared to the password in the table. If they match we go to test1.php If they don't we go to test2.php test1.php test2.php and test3.php are holding pages which just display "Success", "incorrect password" or "No User" to check that this codeworks and will be replaced later.

When I go through the login page and put an invalid user name, I get sent to test3.php - this is correct.

However, if a put in a valid user name and a password, I get sent to test2.php (incorrect password) regardless of the password used being correct or not. Which makes me think the validation is not working.

This is the code from the input page for username & password:

<div style="display: table-row">
<div style="display: table-cell" class="w3-padding">
<label>User ID:</label>
<input class="w3-input w3-text-black" name="username" required>
</div>
<div style="display: table-cell" class="w3-padding">
<label>Password:</label>
<input class="w3-input w3-text-black" type="password" name="pwd" required>
</div>
</div>

Thanks in advance for any assistance.

<?php
    //get config and environment files - includes session script and database ID
    require_once("config.php");
    require_once("env.php");
    
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) 

    {   die("Connection failed: " . $conn->connect_error);  }
    
$userid = $_POST["username"];
$sql = "SELECT UserID, UserName, Psswrd, FirstName, LastName, UserType FROM Users WHERE UserName = '$userid';";

$result = $conn->query($sql);
$row = mysqli_fetch_assoc($result);
if ($result->num_rows == 1) 
   {   $pwcheck = $row['Psswrd'];
        if(password_verify($_POST["pwd"],$pwcheck))
        {   header("Location: test1.php");
                exit();     
        }else
        {   header("Location: test2.php");
                exit();     
        }                       
    }else
    {   header("Location: test3.php");
