I want to use cookies to remember the usernames I add and replace the default value with the last used username.
I have the following html code:
<link href = "login.css" rel = "stylesheet">
<html>
<head>
</head>
<body>
<form action="login.php" method="post">
<label for="uname"><b>Username</b></label>
<input type="text" placeholder="Enter Username" value ="?" name="uname" required>
<label for="psw"><b>Password</b></label>
<input type="password" placeholder="Enter Password" name="psw" required>
<button type="submit">Login</button>
<label>
<input type="checkbox" checked="checked" name="remember"> Remember me
</label>
</form>
</body>
</html>
this is login.php:
<?php
echo("Success!");
if($_SERVER["REQUEST_METHOD"] == "POST"){
setcookie("username", $_POST["uname"], time()+30*24*60*60);
}
?>
I want to replace the '?' from
<input type="text" placeholder="Enter Username" value ="?" name="uname" required>
with the value held by the cookie.
This is what I do in value.php:
<?php
if(isset($_COOKIE["username"]))
echo $_COOKIE["username"];
?>
Can I do something like:
<input type="text" placeholder="Enter Username" value ="value.php" name="uname" required>
so I don't have to write the php code there? This doesn't work, the value I get in the form is "value.php"
I'm not too familiar with PHP, but can't you just do:
<input type="text" placeholder="Enter Username" value="<?php include 'value.php'?>" name="uname" required>
or something like that?

Implementing forms with bootstrap's classes, in a first page I wrote this code
<form action="dologin.php" method="post">
<input type="text" name="email" class="form-control" placeholder="Username">
<input type="password" name="password" class="form-control" placeholder="Password">
<input type="image" src="img/login.png" alt="Login">
</form>
and in dologin.php I tried to retrive the data in this way
$email = $_POST['email'];
echo $email;
It doesn't work, it doesn't print anything.
But if I use the get method, in first page:
<form action="dologin.php" method="get">
<input type="text" name="email" class="form-control" placeholder="Username">
<input type="password" name="password" class="form-control" placeholder="Password">
<input type="image" src="img/login.png" alt="Login">
</form>
In dologin.php
$email = $_GET['email'];
echo $email;
It works printing what was input in the form.
Thank you for helping.
I believe it has something to do with the "image" input.
have you considered using a button element instead?
<button type="submit" name="someName" value="someValue"><img src="someImage.png" alt="SomeAlternateText"></button>
Try this :-
<form action="dologin.php" method="post">
<input type="text" name="email" class="form-control" placeholder="Username">
<input type="password" name="password" class="form-control" placeholder="Password">
<input type="image" src="img/login.png" type="submit" alt="Login">
</form>
And in dologin.php :
email = $_POST['email'];
echo $email;

How to get input field value using PHP
(7 answers)
Closed 8 years ago.
I am trying to register a new user by posting their form data to the database via a php scriptregister.php but I am getting an array of errors when I hit register, the data is supposed to be validated by a second script called validate.php. My register.php is shown below. Same errors exist when the form is empty and when is filled.
<?php require('scripts/validate.php');?>
<!DOCTYPE html>

I'll greatly appreciate guys.
Give your inputs a name property.
E.g:
<input type="text" id="username" name="username" />
The issue is that it's looking for name, but it doesn't exist.
This goes for all of your input fields, not just that specific one and not just for type="text".
When you POST data using a form, you need to specify the name of the data using the name attribute. Replace all of the id attributes with name and your form will work. For example:
<input type="text" id="username"/>
should become:
<input type="text" name="username"/>
Replace all elements' id with name. When form is submitted the element's information is submitted with associated name and not id.
e.g. <input type="text" id="username" name="username"/>
This isn't a PHP error, it's a HTML one.
POSTS variables are stated using the name tag in HTML, not the id tag.
Your inputs should look like this:
<input type="text" name="username"/>
Just change the id tags to name tags, and it should work.
Change your HTML Form

as others have stated here, your form elements need a name attribute. the id attribute is great for referencing the form elements in JavaScript or CSS. but with $_POST variables you need to specify the name. Hope this gives an understanding to why you need the name attribute instead of the id attribute.
I want my hidden input field to get the page title as its value.
This is my testmail.php code.
<p>From: <?php echo $_POST['name']; ?></p>
<p>Subject: <?php echo $_POST['subject']; ?></p>
<p>Email: <?php echo $_POST['email']; ?></p>
<p>Phone Number: <?php echo $_POST['phone']; ?></p>
<p style="width:300px;">Message: <?php echo $_POST['message']; ?></p>
and this is my form code
<form action="testmail.php" method="post" class="cf">
<label for="name">* Name:</label>
<input type="text" name="name" placeholder="Your Name">
<input type="hidden" name="subject" value="<?php value $_POST['pagetitle']; ?>">
<label for="email">* Email:</label>
<input type="text" name="email" placeholder="Enter a valid Email Address">
<label for="phone"> Phone:</label>
<input type="text" name="phone" placeholder="Enter areacode and number">
<label for="message">* Message:</label>
<textarea name="message"></textarea>
<button type="input">Send</button>
</form>
Is there a way to get the title automatically?
Here's a pure javascript way using the onsubmit event.
<form onsubmit="this.subject.value=document.title;">
<input type="text" name="subject" value="" />
<input type="submit" />
</form>
To give you a better understanding of the onsubmit event as the name suggests it executes the contained javascript when the user submits the form. The operation this.subject.value=document.title working from right to left basically says assign the value of document.title to the value attribute of the element with the name of subject in this specific form.
Using your existing form it should look like this (I added the onsubmit event and fixed up errors in your html as well as added the appropriate id's to form elements):
<form action="testmail.php" method="post" class="cf" onsubmit="this.subject.value=document.title;">
<label for="name">* Name:</label>
<input type="text" id="name" name="name" placeholder="Your Name" />
<input type="hidden" name="subject" value="" />
<label for="email">* Email:</label>
<input type="text" id="email" name="email" placeholder="Enter a valid Email Address" />
<label for="phone"> Phone:</label>
<input type="text" id="phone" name="phone" placeholder="Enter areacode and number" />
<label for="message">* Message:</label>
<textarea id="message" name="message"></textarea>
<input type="submit" name="submit" value="submit" />
</form>
This will set the value of your hidden input field once the page has finished loading.
<script>
$(function() {
$('input[name="subject"]').val($('title').text());
});
</script>
You can use JavaScript to do so, assuming you're using jQuery, bind submit event to your form
$('your_form_selector').on('submit', function(){
$('<input />').attr('type', 'hidden')
.attr('name', 'title')
.attr('value', document.title)
.appendTo($(this));
});
I am trying to use Angular.
I am trying to Post Form of Angular, which have been done successfully, it is posting in JSON, But Problem is it only Post the input fields which have values, if i have NOT filled a textbox then it will NOT post that textbox value and fieldname, so how to know in controller which input fields have been posted.
Also how to send it to the model??
Here what i have done so far.

Controller:
public function angform()
{
$get=file_get_contents('php://input');
$json_get=json_decode($get);
foreach($json_get as $key=>$value){
// i think something it has to do here.
}
$this->load->model('datamodel');
$this->datamodel->insert($data);
}
here is the screenshot, i have filled three fields so it posted the values of three fields only.
public function angform()
{
$get=file_get_contents('php://input');
$json_get=json_decode($get);
foreach($json_get as $key=>$value){
$data[$key]=$value; //Worked For Me.
}
$this->load->model('datamodel');
$this->datamodel->insert($data);
}
i check like this :-
if($this->input->get_post('male'))
{
// rest code goes here
}
Change your input name to match exactly like the database attribute(column) name. In that way you will not have to check anything:
$data = $this->input->post(null); #get the post array
$this->db->insert('table', $ata);
Ok i have a Edit Form in AngularJS and i want show data in textboxes through angular databindings.

Here is the Json Array I am Getting From the Controller
JSON:
{"datas":[{"UserID":"168","UserName":"fdaa","Cnic":"23424","Email":"pak#gmail.com","Password":"asdad","Age":"12","Gender":"Male","Picture":null,"InGameName":"fds","ContactID":null,"GroupID":null,"ClanID":null}]}
But How to show these values in TextBoxes through Angular Data bindings?
Or if i am Doing Something Wrong Please Redirect me to my mistakes so i could solve my mistakes.
I am not sure whether I am getting you right or not. But I think If you are using $scope and ng-model, they are doing their job perfectly. You are using absolutely correct.
With the $http.post() you can save the data. At the same time data will be present in the text boxes.
What exactly you want to do. Please explain a bit more so that folks can try to explain you more.
