How do I save content from summernote?
To save content from Summernote, you can follow these steps:- Initialize Summernote on your HTML page using the appropriate code:
$(document).ready(function() {
$('#summernote').summernote();
});
- Create a button or other user interface element that will trigger the save action.
<button id="save-btn">Save</button>
- Add an event listener to the save button that will extract the content from Summernote and save it to your server or client-side storage.
$('#save-btn').click(function() {
var content = $('#summernote').summernote('code');
// Save content to server or client-side storage
});
In the above code, $('#summernote').summernote('code') retrieves the HTML content from Summernote, which can then be saved using an appropriate method, such as an AJAX request to your server or storing the content in a client-side storage mechanism like local storage or cookies.
Can you show me how?
Certainly! Here's an example of how to save content from Summernote using AJAX to send the data to a PHP file on the server:- HTML code for the Summernote editor and Save button:
<div id="editor"></div> <button id="save-btn">Save</button>
- JavaScript code to initialize Summernote and save the content using AJAX:
$(document).ready(function() {
$('#editor').summernote({
height: 300
});
$('#save-btn').click(function() {
var content = $('#editor').summernote('code');
// Send data to server using AJAX
$.ajax({
url: 'save.php',
type: 'POST',
data: {content: content},
success: function(response) {
console.log(response);
}
});
});
});
- PHP code to handle the AJAX request and save the content to a file: save.php file
$content = $_POST['content'];
$file = 'saved-content.html';
if (file_put_contents($file, $content) !== false) {
echo 'Content saved successfully.';
} else {
echo 'Error: Unable to save content.';
}
In the above code, $_POST['content'] retrieves the HTML content from the AJAX request and file_put_contents() saves the content to a file on the server. The success or failure of the operation is then echoed back to the client as a response.
Note that this is just an example and you may need to modify the code to fit your specific requirements, such as changing the file name, directory, or storage mechanism used for saving the content. On the next page all you will have to do is copy and paste these codes to see them work!
