jquery - x-editable - reset 'new record' after submit - php

I have been trying to figure this out for hours to no avail.
I have the following
http://vitalets.github.com/x-editable/docs.html#newrecord
the new record module/code. Its functionality is, once all the rows have their data, and it is submitted, it retains its value so that it can stay editable.
I have tried adding input, select clearing code in the success of the ajax request and tried putting the .editable function inside an ajaxComplete function to see if it would reload the element on submit but it didnt. look at the demo. enter data, and submit. it then makes the data "permanent" so that it can continue to be editable.
I have removed the code that hides the button.
What i want it to do is, submit the record and reset so i can submit another with the form being 'Empty' and back to default.
I am developing an equipment tracker and would love if techs could just enter records, one after another. im sure its a simple fix to reset the form, i just cannot figure it out.
I have attached a screencast video of it.
http://www.youtube.com/watch?v=dPDuQCgOOSw

as it's popular question, I've added Reset button to documentation.
$('#reset-btn').click(function() {
$('.myeditable').editable('setValue', null) //clear values
.editable('option', 'pk', null) //clear pk
.removeClass('editable-unsaved'); //remove bold css
$('#save-btn').show();
$('#msg').hide();
});
It's better to use .editable('setValue', null) instead of .text('Empty') as we need also to reset internal value.
HTH

If you look how the "save new user button" is implemented, it just selects the anchor tags that have classname myeditable
Either you bind a function to your 'reset' button or have this script onclick
IF onclick:
jQuery.each($('.myeditable'),function() {
$(this).text('Empty') ; //this is your default text
});
OR as a function
function reset_myeditable()
{
jQuery.each($('.myeditable'),function() {
$(this).text('Empty') ; //this is your default text
});
}
and attach this to the onclick handler of your reset button
This I assume you will be putting a 'reset' button
EDIT
Ok zoom in to your $('#save-btn').click(function() success handler
success: function(data, config) {
if(data && data.id) { //record created, response like {"id": 2}
$(this).editable('option', 'pk', data.id);
//remove unsaved class
$(this).removeClass('editable-unsaved');
//show messages
var msg = 'New user created! Now editables submit individually.';
$('#msg').addClass('alert-success').removeClass('alert-error').html(msg).show();
$('#save-btn').hide();
$(this).off('save.newuser');
/**this the edited part**/
jQuery.each($('.myeditable'),function() {
$(this).text('Empty') ; //this is your default text
});
/**end of edit**/
} else if(data && data.errors){
//server-side validation error, response like {"errors": {"username": "username already exist"} }
config.error.call(this, data.errors);
}
},

What I see is NOT what I get

(simplified) Scenario: a remote MySql DB and an HTML page with 2 buttons: SHOW and SELECT. The SHOW loads a single record and displays the fields in a form.
Everything is ok on this side.
The SELECT was made with a new approach for me:
I pass a parameter to a PHP function to query the DB and create an html file with the resuls.
This file is a series of <UL><LI><a id="1"...data..</LI></UL> to be inserted within a DIV.
One of the <LI> contains a link that, when clicked, calls the SHOW function. The record identification is made by mean of the ID associated to the anchor.
This procedure works fine; I get the new HTML segment (that I can check on the remote web server).
It is inserted (???) inside my DIV and the content is correctly displayed on screen, but... it does not exist.
Clicking on the links does not activate the SHOW procedure (actually, an Alert with the calling ID is never shown).
Looking to the html page source from Mozilla it still shows the previous content, without the new added (or replaced) code.
This is the reason for this post's title: I see something that really is not there.
Possibly, I should have AJAX to 'refresh' its visibility of the DOM, but and do not understand how.
This is the piece of JQuery script that I use to get the new content:
$("#select").click(function() {
$.ajax({
url: "new_record_list.php",
cache: false,
success:
function(recNumber)
{
$("#selected").val(recNumber); //ok
$("#recordList").load("list.txt"); //'list.txt is created by new_record_list.php
alert($("#recordList").html()); //this is OK
}
});
});
Everything is ok, but where is the meat?
Most likely the listener you created did not attach to the new dom nodes.
You can fix this by attaching a listener to a parent element that exists at page creation or even the document like so:
$(document).on('click', '.show', function() {
//click event
});
Replace ".show" with the jquery selector for the links
Since I'm unable to comment on your new post due to rep:
Remove the click event handler inside the loadRecord function.
The click event was already bound at the top of your script. What happens is that you click, activate the load record function which binds a new click handler, triggering the action on all the clicks following it.
The load record should look like this instead:
function loadRecord(){
ind = $(this).attr("id");
$("#thisRecord").val(ind); //shows the clicked record
$.get("show_record.php",{id:ind}, function(gotString)
{
ptr=0; //used to fetch fields
pos=0;
lun = gotString.length;
if (lun==0) {
alert ("Empty string!");
return false;
};
// fetch received keys and values then fills the fields
while (ptr < lun) {
..... //not interesting here
}; //while
});
return false; //required!
};
Also, you should replace
$(document).on('click', '.compLink', function() {
loadRecord();
});
with
$(document).on('click', '.compLink', loadRecord);
And loadRecord will be passed the mouse event as an argument. $(this) will also refer to the link you clicked inside the loadrecord function.
Otherwise you need to pass the element clicked into that function.
One issue I can see straight away is the AJAX call, it should be along the lines of:
$( "#select" ).on( "click", function ()
{
$.ajax( {
url: "new_record_list.php?record=MY_RECORD_VALUE",
type: "GET",
success: function ( response )
{
$( "#selected" ).val( response );
$( "#recordList" ).html( function ()
{
$.ajax( {
url: "list.txt",
typ: "GET",
success: function ( response2 )
{
$( "#recordList" ).html( response2 );
}
} );
} );
alert( $( "#recordList" ).val() );
},
beforeSend: function()
{
$( "#recordlist" ).html( "Loading..." );
$( "#selected" ).val( "Loading..." );
}
} );
} );
This will give a better result from the $.ajax call that you have made.
The .load() method can be quite unreliable at times, hence why it is (IMO) better to make an ajax within an ajax, because that's what your doing with less control effectively.
Where you have done the function(recNumber) is kinda wrong I'm afraid, whats brought back from the AJAX call is the response, everything that would be shown should you be using it as an actual page, e.g. if you had:
<table>
<tr>
<td>Row 1</td>
</tr>
<tr>
<td>Row 2</td>
</tr>
</table>
<input id="id_valued" value="2" />
Then this whole thing would be returned, not just the id_valued input field.
I followed the hints from Erin plus some other suggestion found on this forum and now the program ALMOST works.
Actually it does, but when a new set of records is loaded, to update the display (that is to call the loadRecord function) it is necessary to click twice on a link, the very first time only. All next clicks reacts immediately.
I try to post the entire script, for you experts to see what I hardly did:
<script type="text/javascript">
$(document).ready(function()
{
$(document).foundation();
var $scrollbar = $("#scrollbar1"); //other stuff
$scrollbar.tinyscrollbar();
//Erin suggestion + my understanding
$(document).on('click', '.compLink', function() {
loadRecord();
});
/* =========== ADD Rows ============================== */
/* action called by hitting the "selectRow" button.
/* query the DB and get a list of rows (5 fields each)
/* that are then inserted into the '#recordList' DIV.
/* Each rows has format:

*/
$("#selectRow").on( "click",function()
{
$.ajax(
{
url: "new_record_list.php",
type: "GET",
success: function(recNumber) //if ok, we get the number of records
{
$("#selectedRecords").val(recNumber); //show how many records we got
$("#recordList").load("newRecords.txt"); //loads the remote text file into the DIV
}
});
});
/* ====================================================== */
/* =========== LOAD Record ============================== */
/* loads and displays an entire record from DB,
/* based on the ID of clicked link with class="compLink"
/* in '#recordList' DIV.

*/
function loadRecord(){
$(".compLink").click(function(event)
{
ind = $(this).attr("id");
$("#thisRecord").val(ind); //shows the clicked record
$.get("show_record.php",{id:ind}, function(gotString)
{
ptr=0; //used to fetch fields
pos=0;
lun = gotString.length;
if (lun==0) {
alert ("Empty string!");
return false;
};
// fetch received keys and values then fills the fields
while (ptr < lun) {
..... //not interesting here
}; //while
});
return false; //required!
});
};
/* ====================================================== */
return false;
});
</script>
I hope this is clear enough. Thanks

How to reload - update de DOM after AJAX code injection?

I thought the easiest way would be to explain it with an image of what I have.
Summary -
I have a form to submit posts (pretty much like what you would find in twitter). Within each post there is an <ol> where comments to that post will reside.
Problem -
When I submit the first comment (button submit 2 in the picture), it doesn't call the ajax and just goes to a page where it presents me the php output of the comment. It seems it is not reloading or aplying DOM events to that portion of code. If I go back, the comment is presented (because it refreshs the page) and when adding the 2nd comment, everything goes normal, as expected. The problem is just the first comment.
Flow -
1) insert new post
2) click the textarea, put some text and press submit
3) Jumps to a page where php output for comment is presented
3a) no ajax call is done. It never enters the code
Could you please help me out understand what is going on? Thanks in advance.
In case you need more of the code just tell me.
JS (post_comment.js - associated with submit 2 in picture. I use ajaxForm - jquery form plugin - though I also tried with the standard .ajax call and the result is the same)
$(function () {
var options = {
success: function (html) {
var arrHTML = html.split(',');
var postId = $.trim(arrHTML[0]);
var html_code = arrHTML[1];
$('ol#post_comment_list' + postId).load(html_code);
//$('ol#post_comment_list'+postId 'li:first').slideDown('slow');
$('.footer-post').hide();
$('.comments-feed').delay(2000).slideUp({
duration: 1000,
queue: true
});
$('.small-textarea-main-feed').removeClass('set-large');
resetForm($('.footer-comment'));
},
error: function () {
alert('ERROR: unable to upload files');
},
complete: function () {
},
};
$(".footer-comment").ajaxForm(options);
function ShowRequest(formData, jqForm, options) {
var queryString = $.param(formData);
alert('BeforeSend method: \n\nAbout to submit: \n\n' + queryString);
return true;
}
function resetForm($form) {
$form.find('input:text, input:password, input:file, select, textarea').val('');
$form.find('input:radio, input:checkbox')
.removeAttr('checked').removeAttr('selected');
}
});

Sending ajax request for each element?

I have an app that has rows, each row contains data. The rows are created by the user (just cloning a sample row).
My ajax function looks like this.
save : function(el) {
//Renaming the properties to match the row index and organize
jQuery('#application-builder-layout .builder-row').each(function(row) {
// Iterate over the properties
jQuery(this).find('input, select, textarea').each(function() {
// Save original name attr to element's data
jQuery(this).data('name', jQuery(this).attr('name') );
// Rewrite the name attr
jQuery(this).attr('name', 'application[rows]['+row+'][elements]['+jQuery(this).attr('name')+']');
});
});
//Looping through each row and saving them seperately with new rowkey
setTimeout(function() {
// Iterate over the layers
jQuery('#application-builder-layout .row-box').each(function(row) {
// Reindex layerkey
jQuery(this).find('input[name="rowkey"]').val(row);
// Data to send
$data = jQuery('#application-builder-layout .row-box').eq(row).find('input, textarea, select');
//$data = $data.add( jQuery('#application-builder-layout') );
jQuery.ajax(jQuery('#form').attr('action'), {
type : 'POST',
data : $data.serialize(),
async : false,
success: function( response ) {
//console.log( response );
}
});
});
}, 500);
},
This is the jQuery, it's application style format so this function is inside a var and is called inside a submit function, the problem is not the ajax, looking at it in the console it saves the data fine, just like I have before.
The Problem I cant get all the data into the database (only the last ajax request) take a look below at "Form Data" it shows what my ajax data looks like and how it's inserting into the DB vs how it should insert, I am using json encode and usually this works, but recently I switched to OOP style coding in PHP so I am not sure if that changes anything?
The PHP:
class MyApp {
const Post_Type = 'page';
public function __construct() {
// register actions
add_action('init', array(&$this, 'init'));
}
public function init() {
// Initialize Post Type
add_action('save_post', array(&$this, 'save_post'));
}
//The main save method
public function save_post($post_id) {
// Empty the builder
if($_POST['rowkey'] == 0) {
$builder = array();
}
$builder['rows'][$_POST['rowkey']] = $_POST['application']['rows'][$_POST['rowkey']];
$builder = esc_sql(json_encode($builder));
if(defined('DOING_AUTOSAVE') && DOING_AUTOSAVE) {
return;
}
if($_POST['post_type'] == self::Post_Type && current_user_can('edit_post', $post_id)) {
// Update the post's meta field
update_post_meta($post_id, 'MY_DATABASE', $builder);
} else {
return;
}
}
}
The above works fine, except its not inserting the data as an array just inserting the last ajax post call, not each. I am sure in my save method I need to reconfig that somehow, but I am just hacking away and cant find info on the web, so I could really use some insight.
I hope I provided enough.
My code summed up: Just to be clear on whats going on here, let me you some basic HTML of my app.
//This gets cloned and the jQuery renames the rowkey to match the index.
<div class="row-box">
<input type="hidden" name="rowkey" value="0">
<div class="builder-row">
<textarea style="display: block;" name="html"></textarea>
<textarea style="display: block;" name="breakingbad"></textarea>
</div>
</div>
So summed up lets say there is 4 rows, the jQuery renames each row, then loops through each and submits an ajax call for each of them. Then the PHP handles the $_POST, in prior applications working with my custom DB I got it to work but working with wp database I am having issues, maybe I am missing something in my method?
Form Data: the ajax form data looks like this (this is the form data inside headers which can be found in the console(firbug) or network(chrome))
//First element
rowkey:0
application[rows][0][elements][html]:A
application[rows][0][elements][breakingbad]:123
Then if there is another row ajax posts again
//Second element
rowkey:1
application[rows][1][elements][html]:B
application[rows][1][elements][breakingbad]:456
So an and so forth, the database looks like this
{"rows":{"2":{"elements":{"html":"B","breakingbad":"456"}}}}
It should be more like this
{"rows":[{"elements":{"html":"A","breakingbad":"123"},{"elements":{"html":"B","breakingbad":"456"}]}
Holy Smokes Batman: I think I got it, It all resides inside how I handle the $_POST ill update soon with an answer..
The database looks good like this
{"rows":[
{"elements":{"html":"A","breakingbad":"123"}},
{"elements":{"html":"B","breakingbad":"456"}}]
}
Now I can continue to build.. whew this was a MASSIVE headache.

Using one delete function for a post jquery request of php request

I'm looking to find out how I can accomplish this next task. I have a controller that loads a view with a table that lists pages in my database. In every row that is made in the table there is a spot for a icon that when clicked will do one of two things.
If the user does not have javascript enabled:
Clicking on the icon will redirect to the delete function in the controller with id of the page as a paramter
Delete controller function will run delete function in model sending page id to delete model function
Delete function in model will delete the page from the database and when returned back to page controller delete function it will redirect back to index function to show list of pages table again.
After redirect it will display a title and message as to a success/fail.
If the user does have javascript enabled:
Send a post to the delete function in controller with jquery post
method with the data page id
Delete controller function will run delete function in model sending page id to delete model function
Delete function in model will delete the page from the database and when returned back to page controller delete function it create a message array for the json object to return to the success function of the post request.
A message with my pnotify plugin will create a message that is formed from that json object and display it to the user
What I would like to know is with doing this how to properly accommodate for these two scenarios? I have started attempting this but would like to some clarification if I have made a mistake so far.
<?php
// Controller delete function
public function delete($content_page_id)
{
if (isset($content_page_id) && is_numeric($content_page_id))
{
$content_page_data = $this->content_page->get($content_page_id);
if (!empty($content_page_data))
{
//update is ran instead of delete to accompodate
//for the soft delete functionality
$this->content_page->update('status_id', 3);
if ($this->input->is_ajax_request())
{
//return json data array
}
}
}
}
?>
Global JS file to be used for multiple tables with delete buttons
/* Delete Item */
$('.delete').click(function(event) {
event.preventDefault();
var item_id = $(this).attr('rel');
$.post(<?php echo current_url(); ?>'delete', { item_id : item_id }, function(data)
{
if (data.success)
{
var anSelected = fnGetSelected( oTable );
oTable.fnDeleteRow( anSelected[0] );
}
}, 'json');
});
I think that you should have two functions in PHP:
public function delete($content_page_id) {
// Your delete code
return "a string without format";
}
public function deleteAjax($content_page_id) {
return json_encode($this->delete($content_page_id));
}
So, when the user has JS enabled, you call deleteAjax passing a parameter in your $.post function to let PHP know that JS is enabled:
$.post(<?php echo current_url(); ?>'delete', { item_id : item_id, js: 1 }, function(data)
{
if (data.success)
{
var anSelected = fnGetSelected( oTable );
oTable.fnDeleteRow( anSelected[0] );
}
}, 'json');
And if JS is disabled, call the other function. You should use an AJAX specialized controller instead a function in the same class.
1) As far as "displaying a message" - the view-itself could be ready for a 'message' if one exists. Bringing us back to...
2) Can you have your delete function return the message you want displayed? Your AJAX approach will ignore this message while your View will display it...
3) I agree that your 'Controller delete function' should 'finish' with different outcomes based on whether the request is AJAX or not. I like what #Skaparate (answered Aug 30 at 18:37) was doing with adding: js:1 In your delete function, you could use this in a simple conditional:
if js = 1
header('HTTP/1.1 200');
else
call view and include/pass-in the 'message'

Hiding in foreach loop

I am getting json in "data" and passing it in for loop. Onclick of buy button, it goes to the App function. On success I need to hide the buy button and display the download label.
My problem is onclick of 1st buy button, download link for both the buttons appear.
Ideally oneclick of first buy button, buy button should be hidden and download label should appear. similarly oneclick of second buy button, buy button should be hidden and download label should appear.
How do I get particular id of each button so that I can hide one at a time?
Please help me out
function (data)
{
var Class ='';
for (var i=0; i <data.length;i++)
{
Class += '<div name="buy\''+data[i].id+'\'" class="btn btn-primary btn-small" onclick="buy(\''+data[i].identifier+'\',\''+data[i].id+'\',\''+data[i].url +'\'); return false;" href=""></div><div class="download\''+data[i].id+'\'" id="download">D<span style="font-size:15px"></span></div>';
}
return Class;
}
App = function(identifier, app_id, url) {
$.ajaxSetup({
data : {
csrf_test_name : $.cookie('csrf_cookie_name')
}
});
var jqxhr = $.post(SITE_URL + 'admin/appstore/purchaseApp', {
identifier : identifier,
ap_id : ap_id
}).done(function(data1) {
obj = JSON.parse(data1);
bootbox.alert(obj.status, obj.label);
$("#download").html('<a href='+download_url+app_id+'>Download!</a>');
});
};
it is for loop am using.. am passing '; now how do I hide buy id? $("#buys"+"'"+data[i].id+"'").hide(); is this the right way? It gives me error
if you look at the actual markup generated in Class, you will see that your buy buttons don't have an id at all. perhaps something like
Class += '<div id="buy-button-'+data[i].id+'" name="...
Now you have a unique id on each button. The next part of your problem is knowing which button to remove after a successful Ajax call. You will need to include that in the data1, returned from the server. For the sake of argument, let's say the server returns the value in your data1 object as app_id. Then all you need to do is
jQuery('#buy-button-'+data1.app_id).hide();
Slightly off-topic, I'm not too keen on the way you're using single quotes in the buttons' name attributes, either, but I don't think that's relevant here.
