How to use jquery to populate a form from database record on the same page


How to use jquery to populate a form from database record on the same page

I wish this helpful for you There's a couple possible solutions you can do here.
First, you need to switch over to mysqli or PDO instead of mysql. Since you are already using mysql, mysqli is VERY similar and won't take much effort to make the change.

Using 1 HTML form: ask user for unique identifier, get record from database, parse into JSON, populate HTML page form us

Using 1 HTML form: ask user for unique identifier, get record from database, parse into JSON, populate HTML page form us

I wish this helpful for you One of the main things I saw here is that you don't understand the process of stopping a form submit, performing a request in the background, and then handling the data that is returned, so I'm going to outline this for you as simply as possible and hopefully it will help.
First, we need to capture the form submit, in jQuery, we can do it like this ->
code :
$('#json-hierarchal').submit(function(){});
$('#json-hierarchal').submit(function(event){
  event.preventDefault(); // the page will no longer refresh on form submit.
});
$('#json-hierarchal').submit(function(event){
  event.preventDefault(); // the page will no longer refresh on form submit.
  var resCheck = $(this).find('input[class="reservationid"]').val(); //now we have the reservation ID, let's perform our check.
  $.ajax({
    url: 'searchres.php',
    type: 'POST', //default is GET, you are using POST(*SEE: [1])
    data: 'resid='+resCheck,
    success: function(data){//data is all the info being returned from the php file
      var jsonData = $.parseJSON(data);//parse returned JSON data so we can use it like data.name, data.whatever
      //I don't know how $.populate works, so I'm assuming we find each item returned in the json array, iterate over each occurence, and run populate on it?     
      $.each(jsonData, function(index,value){
        $('#form-hierarchal').populate(value);
      });
    }
  });
});
Using a form to populate a database and land on a page with the information submitted

Using a form to populate a database and land on a page with the information submitted

I hope this helps you . I have a form on my new view that takes in "url" and "title". When I submit my "url" & "title" I am taken to a blank create view. Ideally I would like to populate my database and land on a page that shows the title and link for that project. , You just have to do this
code :
def create
  @link = Link.new(params[:link])
  if @link.save
    redirect_to @link
  else
    render :new
  end
end

def show
  @link = Link.find(param[:id])
end
resources :links
How do I pull data from my MySQL database to pre populate a form on page load?

I wish this help you Assuming you already have a MySQL database setup and filled with data, I'd recommend reading about PHP PDO: http://php.net/manual/en/book.pdo.php
More specifically have a look at how to connect to your database: http://php.net/manual/en/pdo.connections.php
code :
$user = <INSERT USER>;
$pass = <INSERT PASS>;
$dbh = new PDO('mysql:host=localhost;dbname=<DATABASE NAME>', $user, $pass);

$stmt = $dbh->prepare("SELECT * FROM login WHERE email = :userEmail");
$stmt->bindParam(':userEmail', $userEmail);

if ($stmt->execute()) {
    $user = $stmt->fetch(PDO::FETCH_ASSOC);
    // now you can get your user details, for example, $user['username'] or however you have it set up in your database
}

I think the issue was by ths following , The easiest way to go without using databases would be using JSON, stored in a simple .txt file. This however does need some more thinking into security. The most important issue being giving authorization to people to edit your form and hence modify your data.
But to answer your question, I would suggest something as follows:
code :
<form action="action.php" method="POST">
    <select name="restaurant">
        <option value="1">Restaurant 1</option>
        <option value="2">Restaurant 2</option>
        <option value="3">Restaurant 3</option>
        <option value="4">Restaurant 4</option>
    </select>
    <input name="chef" type="text" />
    <input name="special_name" type="text" />
    <input name="special_descr" type="text" />
    <input name="child_name" type="text" />
    <input name="child_descr" type="text" />
    <input type="submit" name="submit" value="Save Data">
</form>
<?php
if (isset($_POST['submit'])) {
    $data = json_decode(file_get_contents("data.txt"), true); // true for assoc
    $data[$_POST['restaurant']] = array(
        "chef" => $_POST['chef'],
        "special_name" => $_POST['special_name'],
        "special_descr" => $_POST['special_descr'],
        "child_name" => $_POST['child_name'],
        "child_descr" => $_POST['child_descr']
    );
    $newData = json_encode($data);
    file_put_contents("data.txt", $newData);
}
?>
<?php
$data = json_decode(file_get_contents("data.txt"), true); // true for assoc

foreach($data as $k => $v) {
    echo "<p>" . PHP_EOL;
    echo "Special Restaurant " . $k . ":<br />" . PHP_EOL;
    echo "Chef: " . $v['chef'] . "<br />" . PHP_EOL;
    echo "Name: " . $v['special_name'] . "<br />" . PHP_EOL;
    echo "Description: " . $v['special_descr'] . "<br />" . PHP_EOL;
    echo "Children: " . $v['child_name'] . "<br />" . PHP_EOL;
    echo "Description: " . $v['child_descr'] . "<br />" . PHP_EOL;
    echo "</p>" . PHP_EOL;
}
?>
form page record not store in database

should help you out You haven't told your form to submit to the submit view, so it is going to the add view which contains no code to do anything with the data.
But don't do that. Use a Django form, and read the documentation on using them in views.
