Storing Form Data To Json
I wrote this code for a sign up form. I want to add the values of email id and password to JSON file in the form of array objects. Here is my html file. <
Solution 1:
You could grep the values from your inputs, and i see you are using jQuery so here is an example for your username input field
var userName = $('#username').val(); //the # tells jQuery you are specifying an elements id, use a . (dot) tho specify a class
You can but this in a json aswell first define a json object
var containerName = {};
Add your values to the container
containerName.userName = $('#username').val();
You can convert your object to a string with
varstring = JSON.stringify(containerName);
These are some basic operations to get values from your form in some kind of structure. Hope this helps.
Solution 2:
As you've tagged your question Php, I'll give you a rough gist of submitting a form, doing some server side validation. And if the validation is satisfied store the data submitted in JSON format in a file.
No Javascript included here.
<?phpif($_SERVER['REQUEST_METHOD'] == 'POST') {
$data = [
'name' => null,
'password' => null,
'cpassword' => null,
'email' => null
];
foreach($dataas$k => $v) {
if(!empty($_POST[$k]))
$data[$k] = $_POST[$k];
}
$validated = true;
if($data['password'] !== $data['cpassword'])
$validated = false;
if(!filter_var($data['email'], FILTER_VALIDATE_EMAIL))
$validated = false;
if($validated) {
if(file_put_contents('/tmp' . '/' . uniqid('json_'), json_encode($data, JSON_PRETTY_PRINT)))
$feedback = 'Thanks. Submission stored.';
}
else {
$error = 'Please fill in all your form fields correctly.';
}
}
?><?=isset($error) ? $error : ''?><?=isset($feedback) ? $feedback : ''?><formmethod="post"><labelfor="name">Name</label><inputtype="name"name="name"id="name"placeholder="e.g. John Doe"required><labelfor="email">Email address</label><inputtype="email"name="email"id="email"placeholder="e.g. john.doe@example.com"required><labelfor="password">Password</label><inputtype="password"name="password"id="password"placeholder="e.g. S3cR3t"required><labelfor="password">Confirm Password</label><inputtype="password"name="cpassword"id="cpassword"placeholder="e.g. S3cR3t"required><inputtype="submit"value="Go"></form>
Of course it could do with some usability enhancements - such as telling the user where exactly they went wrong. But you get the idea.
