I am currently learning Web-Design(HTML,PHP,Javascript) and I have created my own site a file called MySite.html.
I have a signin screen which uses POST method to send data to a file called signin.php.
For now it has a simple check which confirms whether data is inputted or not.
But when I enter the Username and Password, the script tells me that I haven't inputted anything.
Here is the code----->
<form name="signin" action="signin.php" method="POST">
<p><input type="text" id="username" placeholder="Enter Username"></p>
<p>
<input type="password" id="pass" placeholder="Password">
<input type="submit" id="sgnin" value="Sign In">
</p>
<p id="small">
<input type="checkbox" id="rem">Remember me.Forgot password?
</p>
<span><p> </p>
</form>
The php script--->
<?php
if(isset($_POST['username']) && isset($_POST['pass']) && !empty($_POST['username']) && !empty($_POST['pass'])){
echo 'Logged In';
}else die("enter something");
?>
Plz Help!
You are not giving name attribute to your form elements give it like this
<input type="text" id="username" placeholder="Enter Username" name="username">
and
<input type="password" id="pass" placeholder="Password" name="pass">

Would appreciate some help! For some reason, the password entered into the form field:
<div>Confirm Password</div>
<input id="password2" name="password2" type="password" maxlength="100">
Is not registering in the php code below when it comes to grabbing it as a POST variable:
$p2 = $_POST['password2'];
The the php code above is above the html form if that matters... and the form posts to update.php which is the name of the file both of these pieces of code are in.
Should be something like this
<form action="somewhere.php" method="post">
<input id="password2" name="password2" type="password" maxlength="100">
<input type="submit" name="submit">
</form>
And on your somewhere.php, you can check
if(isset($_POST['submit'])){
$p2 = $_POST['password2'];
}else{echo "sorry form not submitted";}
I am trying to get a username and password from an HTML form using $_POST method,
but i am getting an undefined index error with given input.
the form portion of my index file is as follows
<form class="form-signin" role="form"action="" method="post">
<h2 class="form-signin-heading">title<em class='current'>title</em></h2>
<input id="username" type="username" class="form-control" placeholder="Username" required autofocus>
<input id="password" type="password" class="form-control" placeholder="Password" required>
<input name ="submit" type="submit" value="sign in">
</form>
i also have my php script (called auth.php) included in the top of my index file.
this is my auth.php script code sample
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
echo "auth is called";
if(isset($_POST['submit'])){
echo "submit is pressed";
//this if statement enters when submit is pressed
if(empty($_POST['username']) || empty($_POST['password'])) {
echo "Username or Password is empty";
//this if statement enters too, even with input given
}
else{
echo "YAY";
}
}
?>
The "username or password is empty" statement keeps getting printed, even when I enter in a username and password into the input fields. What is the problem
Missing "name" attribute in input fields, it should be
EDIT 2 : Missing type="text" in username input
<input type="text" name='username' id="username" class="form-control" placeholder="Username" required autofocus>
<input name='password' id="password" type="password" class="form-control" placeholder="Password" required>
Correct your form , 1. Name missing, 2. No datatype with the name of username
<form class="form-signin" role="form" action="" name="loginform" method="post">
<h2 class="form-signin-heading">title<em class='current'>title</em></h2>
<input id="username" name="username" type="text" class="form-control" placeholder="Username" required autofocus>
<input id="password" name="password" type="password" class="form-control" placeholder="Password" required>
<input name="submit" type="submit" value="sign in">
</form>
<input id="username" name="username" type="username" class="form-control" placeholder="Username" required autofocus>
<input id="password" type="password" name="password" class="form-control" placeholder="Password" required>
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
echo "auth is called";
if(isset($_POST['submit'])){
echo "submit is pressed";
//this if statement enters when submit is pressed
if(empty($_POST['username']) || empty($_POST['password'])) {
echo "Username or Password is empty";
//this if statement enters too, even with input given
}
else if(empty($_POST['username']){
echo "Username is empty";
}
else if(empty($_POST['password']){
echo "Password is empty";
}
else{
echo "YAY";
}
}
?>
input type = text and name attr required
<input name='username' id="username" type="text" class="form-control" placeholder="Username" required autofocus>
Check values using print_r() or var_dump if you are not getting the desired output.
This will help you to check which part of your code malfunctions. If you have done so, you would have found that there's something wrong only in your html form content, as you wont be having any field content printed and you would have easily sorted it out...
Set the username input's type to "text":
<input name='username' id="username" type="text" class="form-control" placeholder="Username" required autofocus>
<input name='password' id="password" type="password" class="form-control" placeholder="Password" required>
I have just discovered that the isset function is no longer working on my login and register forms. Very strange I though, so I undid everything that I had recently done to see if it was causing it but no luck. If i remove the isset and replace with this;
if($_SERVER['REQUEST_METHOD'] == "POST"){
it works! But I have two forms on one page so I need to check which one is submitted.
Here's the isset function:
if (isset($_POST['submit_login'])) {
And the submit button just so you know it has the correct name;
<input type="submit" name="submit_login" value="Login" class="buttonClassic"/>
The one for the register form is exactly the same but with name submit_reg.
Form:
<form action="<?php echo htmlentities('Login'); ?>" method="post" id="login">
<p class="p1">Already signed up? Log in</p><hr/>
<label for="email">Your email address </label><input type="email" required name="email" placeholder="Email" class="text" id="email">
<label for="password">Your password </label><input type="password" name="pass" required placeholder="Password" class="text" id="password">
<center><input type="submit" name="submit_login" value="Login" class="buttonClassic"/></center>
<div class="center-align-text">
<p class="p3">Forgotten your password?</p>
</div>
</form>
reg form:
<form action="<?php echo htmlentities('Login'); ?>" method="post" id="register" >
<p class="p1">New to NBS? Sign up, it's free!</p><hr/>
<label for="reg_email">What's your email address? </label><input type="email" name="email" required placeholder="Email" class="text" id="reg_email">
<label for="reg_password">Choose a password </label><input type="password" required name="pass" placeholder="Password" class="text" id="reg_password">
<label for="reg_password2">Re-type password </label><input type="password" required name="pass2" placeholder="Re-type password" class="text" id="reg_password2">
<input type="checkbox" name="subscribed" value="subscribed" id="subscribed"><label for="subscribed">Yes, send me email updates from NewBorn Sounds. </label>
<br/>
<input type="checkbox" required="flag" name="terms" value="ticked" id="terms"><label for="terms">I agree to the terms & conditions.</label>
<center><input type="submit" name="submit_reg" value="Sign Up" class="buttonClassic"></center>
</form>
If you need anything more just shout!
Oh and I know I could just submit the form to an external PHP script but I don't particularly want to do that as I would like the user input errors to be outputted to the same page. I know I could just use ajax, which I do, but I am trying to keep javascript as an add-on and not reduce the user experience for no js.
Full HTML:
<div id="login_form_wrapper">
<form action="Login" method="post" id="login" novalidate="novalidate">
<p class="p1">Already signed up? Log in</p><hr>
<label for="email">Your email address </label><input type="email" required="" name="email" placeholder="Email" class="text" id="email">
<label for="password">Your password </label><input type="password" name="pass" required="" placeholder="Password" class="text" id="password">
<center><input type="submit" name="submit_login" value="Login" class="buttonClassic"></center>
<div class="center-align-text">
<p class="p3">Forgotten your password?</p>
</div>
</form>
<form action="Login" method="post" id="register" novalidate="novalidate">
<p class="p1">New to NBS? Sign up, it's free!</p><hr>
<label for="reg_email">What's your email address? </label><input type="email" name="email" required="" placeholder="Email" class="text" id="reg_email">
<label for="reg_password">Choose a password </label><input type="password" required="" name="pass" placeholder="Password" class="text" id="reg_password">
<label for="reg_password2">Re-type password </label><input type="password" required="" name="pass2" placeholder="Re-type password" class="text" id="reg_password2">
<input type="checkbox" name="subscribed" value="subscribed" id="subscribed"><label for="subscribed">Yes, send me email updates from NewBorn Sounds. </label>
<br>
<input type="checkbox" required="flag" name="terms" value="ticked" id="terms"><label for="terms">I agree to the terms & conditions.</label>
<center><input type="submit" name="submit_reg" value="Sign Up" class="buttonClassic"></center>
</form>
</div>
maybe you could do something like this :
if($_SERVER['REQUEST_METHOD'] == "POST"){
if (isset($_POST['submit_login'])) {
//do something
} else {
//do something else
}
}
Form action needs to be a valid url, e.g. "/login.php".
Checkboxes have either the value given (once checked), or they do not appear at all. Best is to double check them: "isset($_POST['mycheckbox']) && 'value' ==$_POST['mycheckbox']".
Show us the php you use to evaluate the form.
How this?
<input type="submit" name="submit_reg" value="Sign Up" class="buttonClassic">
<?php
if($_POST['submit'] == 'Sign Up'){
//do something
}
?>
I have created a login form for my website but currently, it is not working and I am being directed to invalid.php which shows my authentication has failed.
<?php
session_start();
include("scripts/dbconnect.php");
$numrows=0;
$password=$_POST['password'];
$email=$_POST['email'];
$query="select fname,lname,email from mayan_users where (password='$password' && email='$email')";
$link = mysql_query($query);
if (!$link) {
die('login error');
}
$numrows=mysql_num_rows($link);
if ($numrows>0){ // authentication is successfull
$row = mysql_fetch_array($link, MYSQL_ASSOC);
$_SESSION['user']['fname']=$row['fname'];
$_SESSION['user']['lname']=$row['lname'];
$_SESSION['user']['email']=$row['email'];
header("location:../index2.php");
} else {
header("location:../invalid.php"); // authentication was unsuccessfull
}
?>
and here is my login form
<div id="Loginform" style="background-color:fuchsia; width:100%">
<span id="logspan">
<input type="email" name="email" id="email" placeholder="Email" required />
<input type="password" name="password" id="password" placeholder="Password" required/>
<input type="button" name="submit" style="cursor:pointer" id="submit" value="Log In" onclick="logMeIn()" />
</span>
</div>
Your login may need to be to be wrapped in form tags if you aren't submitting it via some other method.
<form method="post" action="">
<span id="logspan">
<input type="email" name="email" id="email" placeholder="Email" required />
<input type="password" name="password" id="password" placeholder="Password" required/>
<input type="button" name="submit" style="cursor:pointer" id="submit" value="Log In" onclick="logMeIn()" />
</span>
</form>
If your PHP is in another document then set the action to the form processor
action="form-processor.php"
(Thanks njk!)
You don't have the form tags.Add them like this
<form method="POST" action="">
<!-- INSERT INPUTS HERE -->
</form>
Try this:
<form id="Loginform" style="background-color:fuchsia; width:100%">
<span id="logspan">
<input type="email" name="email" id="email" placeholder="Email" required />
<input type="password" name="password" id="password" placeholder="Password" required/>
<input type="button" name="submit" style="cursor:pointer" id="submit" value="Log In" onclick="logMeIn()" />
</span>
</form>
First of all, I suggest you to use PDO if your PHP version support it.
Then I suppose that your javascript function sends in the correct way the parameters.
Finally, you could avoid to check the number of rows. Simply
if($row = mysql_fetch_array($link))
{
...
}
else
{
header("location: ../invalid.php");
exit; //It's a good practice
}
I have made this html form, it submits all the information to a MySQL database. Pretty simple stuff.
How do I store the username in a cookie so that once it's entered? I would like to ensure that once the user enters their username once, it pre-populates the username field in the future.
<!-- Message board submissionform -->
<form id="frmMB" name="frmMB" action="insert.php" method="post" enctype="multipart/form-data">
<label class="name"><input name="name" placeholder="Enter your name" type="text" id="name" onFocus="if(this.value=='Enter your name'){this.value=''};" onBlur="if (this.value==''){this.value='Enter your name'};" value="Enter your name" size="80" maxlength="10" ></label>
<br />
<label class="message">
<input name="post" placeholder="Enter a message" type="text" id="post" onFocus="if(this.value==this.defaultValue)this.value='';" onBlur="if(this.value=='')this.value=this.defaultValue;" value="Enter a message" size="80" maxlength="140" data-maxsize="3">
</label>
<br />
<label>
<input name="Submit" class="large button" type="submit" value="submit">
</label>
I think something like this would just do this trick.
setcookie($_POST['name'], $value, time()+3600);
if(isset($_COOKIE['name']) && !empty($_COOKIE['name']))
{
// do some stuff here because the name is set in the cookie.
}
First you need to start a session -> session_start()
Once done so, you have created a public $_SESSION array and can add elements to it. Easiest way to do so is:
<?php
if(isset($_POST['username'])){
sesion_start();
$_SESSION['username'] = $_POST['username'];
}
...
Cheers!
