I am trying to pass form values through post form but nothing shows.
using this HTML5 Text Editor http://suyati.github.io/line-control/
I'm using this method for form and php code
<?php
if(isset($_POST['submit'])){
echo $_POST['txtEditor'];
}
?>
html form i am using
<form method="post">
<textarea name="txtEditor" id="txtEditor" ></textarea>
<input name="submit" type="submit" value="Submit">
</form>
and the java script is
<script src="WYSIWYG-Text-Editor/editor.js"></script>
<script>
$(document).ready(function() {
$("#txtEditor").Editor();
});
</script>
Have checked the doc and apparently you need to set the value by yourself, here is a solution:
Add some code to your initialization code:
<script>
$(document).ready(function() {
$("#txtEditor").Editor();
$('form').submit(function () {
$('#txtEditor').val($('#txtEditor').Editor('getText'));
});
$('#txtEditor').Editor('setText', $('#txtEditor').val());
});
</script>
On form submit we actually set the textarea value with what the user input in the WYSISWYG.
In the next line of code we set the value of the WYSISWYG with what value comes in the textarea (as you requested in your comment).

My if(isset) validation is returning false after I have submitted the form through jQuery ,however works fine when done without jquery. Reason I am using jQuery is because I need to submit multiple forms:
Button
<input class="btn btn-primary" type ="submit" id="myButton"
name="create_record" value="Submit 1">
jQuery:
<script>
$(document).ready(function () {
$("#myButton").click(function (event) {
event.preventDefault();
$("#form1").submit();
// $("#form2").submit();
});
});
</script>
PHP
<?php
if(isset($_POST['create_record'])){
$ecode = $_POST['ecode'];
$ename = $_POST['ename'];
$date = $_POST['date'];
$jobRole = $_POST['jobRole'];
}else{
echo "did not receive anything";
}
?>
Always getting "did not receive anything" . Can someone please help.
The submit button value only gets sent if the form is submitted in the traditional way by a button click. Since you are submitting the form via javascript, you'll need to explicitly include the submit button's value or validate your post data in some other way. If you need the value of the specific button that was clicked, something like this should work:
$("#myButton").click(function (event) {
event.preventDefault();
var el = '<input type="hidden" name="' + $(this).prop('name') + '" value="' + $(this).val() + '">';
$("#form1").append(el).submit();
});
As for your objective of submitting multiple forms at once, I believe it's impossible without using ajax as discussed here. If you need guidance on how to do that, better to open a new question.
Your code, isset($_POST['create_record']) maybe false or it didn't receive any values. If your query is only in one PHP file together with your jQuery, you need to check first your algorithm or use var_dump() for testing. Second, If it didn't work, make an alternative solution for it. Do the proper HTML code when using form or make another PHP file for receiving post purpose only.
<form action="directory_to_another_file" method="POST">
<!-- SOME INPUTS HERE -->
<input type="submit" value="Submit 1" name="create_record">
</form>
Try to test all of your codes.
You have to set form method as "POST" type and if you want to receive the form data in same page then empty the "action" key otherwise give the target link.
<?php
if(isset($_POST['create_record'])){
print_r($_POST);
}
?>
<form action="" method="POST" id="form1">
<input type="text" name="create_record" value="Submit 1"/>
</form>
Submit
<script>
$(function(){
$("#myButton").click(function (event) {
event.preventDefault();
$("#form1").submit();
});
})
</script>
Let me know if it's work for you.
Because of my web style, i don't want to use input & textarea and get information by using $_POST[] and i need to get information that is in DIV element.
For example , I want to get information in this :
<div class="mine" name"myname">
this is information that i want to get and put into database by PHP !
</div>
and :
$_POST[myname];
But i can't do it with $_POST , How can i do it ??
And if this method can't do this , do you know any other method to get information from DIV like this ?
you can call a onsubmit function and make a hidden field at the time of form submission like this
HTML
need to give a id to your form id="my_form"
<form action="submit.php" method="post" id="my_form">
<div class="mine" name"myname">
this is information that i want to get and put into database by PHP !
</div>
<input type="submit" value="submit" name="submit" />
</form>
Jquery call on submit the form
$(document).ready(function(){
$("#my_form").on("submit", function () {
var hvalue = $('.mine').text();
$(this).append("<input type='hidden' name='myname' value=' " + hvalue + " '/>");
});
});
PHP : submit.php
echo $_POST['myname'];
You can use this method. First, with javascript get content of <div>
Code:
<script type="text/javascript">
var MyDiv1 = Document.getElementById('DIV1');
</script>
<body>
<div id="DIV1">
//Some content goes here.
</div>
</body>
And with ajax send this var to page with get or post method.
You would need some JavaScript to make that work, e.g. using jQuery:
$.post('http://example.org/script.php', {
myname: $('.mine').text()
});
It submits text found inside your <div> to a script of your choosing.
You can use following structure;
JS:
$(document).ready(function() {
$("#send").on("click", function() {
$.ajax({
url: "your_url",
method: "POST",
data: "myname=" + $(".mine").text(),
success: function(response) {
//handle response
}
})
})
})
HTML:
<div class="mine" name"myname">
this is information that i want to get and put into database by PHP !
</div>
<input type="button" name="send" id="send" value="Send"/>
You can see a simulation here: http://jsfiddle.net/cubuzoa/2scaJ/
Do this in jquery
$('.mine').text();
and post data using ajax.
Put the content of DIV in a variable like below:
var x = document.getElementById('idname').innerHTML;
This site has been really helpful while writing this program. Unfortunately, I hit a snag at some point, and have boiled the problem down quite a bit since. At this point, I am looking at three files, a .html that contains a form, a .js that contains my event handlers, and a .php that receives my post variables and contains new content for the form.
I am getting the post data from the initial text input just fine. The new form content is set as I would expect. However, after this form content is set to a new input of type button with a class of button, the post method in my button class handler is not setting post data on login.php as I expect it to.
Here is my code:
Contents of interface.html page:
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
</head>
<body>
<form id="interface" action="login.php" method="post">
<input type="text" value="enter username here" name="user"/>
<button id="submit">submit</button>
</form>
<script src='events.js'></script>
</body>
</html>
Contents of events.js file:
$("#submit").click(function(){
$.post(
$("#interface").attr("action"),
$(":input").serialize(),
function(info){$("#interface").html(info);}
);
});
$(".button").click(function(){
var $this=$(this);
$.post(
$("#interface").attr("action"),
{data:$this.val()},
function(info){$("#interface").html(info);}
);
});
$("#interface").submit(function(){
return false;
});
Contents of login.php file:
<?php
if(isset($_POST['user'])){
echo '<input type="button" class="button" value="set data"/>';
}else if(isset($_POST['data'])){
echo 'data is set';
}
?>
You need to wait until the button exists to bind an event to it. Additionally, i'd switch from click to submit and drop the click event binding on .button completely.
//$("#submit").click(function () {
$("#interface").submit(function (e) {
e.preventDefault();
var $form = $(this), data = $form.serialize();
if ($form.find(".button").length && $form.find(".button").val() ) {
data = {data: $form.find(".button").val()};
}
$.post($form.attr("action"), data, function (info) {
$form.html(info);
});
});
//$("#interface").submit(function () {
// return false;
//});
Since the form is not being replaced, and the event is on the form, you no longer need to re-bind anything.
this a simple example in how to submit form using the Jquery form plugins and retrieving data using html format
html Code
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script>
<script src="http://malsup.github.com/jquery.form.js"></script>
<script>
// prepare the form when the DOM is ready
$(document).ready(function() {
// bind form using ajaxForm
$('#htmlForm').ajaxForm({
// target identifies the element(s) to update with the server response
target: '#htmlExampleTarget',
// success identifies the function to invoke when the server response
// has been received; here we apply a fade-in effect to the new content
success: function() {
$('#htmlExampleTarget').fadeIn('slow');
}
});
});
</script>
</head>
<body>
<form id="htmlForm" action="post.php" method="post">
Message: <input type="text" name="message" value="Hello HTML" />
<input type="submit" value="Echo as HTML" />
</form>
<div id="htmlExampleTarget"></div>
</body>
</html>
PHP Code
<?php
echo '<div style="background-color:#ffa; padding:20px">' . $_POST['message'] . '</div>';
?>
this just work fine
what i need to know if what if i need to Serialize the form fields so how to pass this option through the JS function
also i want show a loading message while form processed
how should i do that too
thank you
To serailize and post that to a php page, you need only jQuery in your page. no other plugin needed
$("#htmlForm").submit(function(){
var serializedData= $("#htmlForm").serialize();
$.post("post.php", { dat: serializedData}, function(data) {
//do whatever with the response here
});
});
If you want to show a loading message, you can do that before you start the post call.
Assuming you have div with id "divProgress" present in your page
HTML
<div id="divProgress" style="display:none;"></div>
Script
$(function(){
$("#htmlForm").submit(function(){
$("#divProgress").html("Please wait...").fadeIn(400,function(){
var serializedData= $("#htmlForm").serialize();
$.post("post.php", { dat: serializedData},function(data) {
//do whatever with the response here
});
});
});
});
The answer posted by Shyju should work just fine. I think the 'dat' should be given in quotes.
$.post("post.php", { 'dat': serializedData},function(data) {
...
}
OR simply,
$.post("post.php", serializedData, function(data) {
...
}
and access the data using $_POST in PHP.
NOTE: Sorry, I have not tested the code, but it should work.
Phery library does this behind the scenes for you, just create the form with and it will submit your inputs in form automatically. http://phery-php-ajax.net/
<?php
Phery::instance()->set(array(
'remote-function' => function($data){
return PheryResponse::factory('#htmlExampleTarget')->fadeIn('slow');
}
))->process();
?>
<?php echo Phery::form_for('remote-function', 'post.php', array('id' => ''); ?> //outputs <form data-remote="remote-function">
Message: <input type="text" name="message" value="Hello HTML" />
<input type="submit" value="Echo as HTML" />
</form>
<div id="htmlExampleTarget"></div>
</body>
</html>
I have an HTML form that currently just posts the data directly to a PHP file. I want to update the code so that the submit button sends the data to a JavaScript function so that I can create an AJAX function. Is it possible for the submit button to activate a JavaScript function rather than posting to a php file? The only thing I have come up with is below, which quite obviously does not work:
<html>
<head>
<script type="text/javascript">
function ajax(){
//...
}
</script>
</head>
<body>
<form action="ajax();">
<!-- ... -->
<input type="submit" value="Submit" />
</form>
</body>
</html>
You can give the "submit" input a "click" handler that explicitly prevents the default behavior from being carried out.
<input type='submit' value='Submit' onclick='ajax(event)'>
Then in the function:
function ajax(event) {
if ('preventDefault' in event) event.preventDefault();
event.returnValue = false; // for IE before IE9
// ...
}
edit #Esailija points out correctly that another option is to handle the "submit" event on the <form> element instead. The function would look pretty much the same, in fact exactly the same, but you'd wire it up like this:
<form id='yourForm' onsubmit='ajax(event)'>
That will also trap things like the "Enter" key action, etc.
Of course you can. But it's more useful to call your Javascript function in the input like this :
<input type="submit" value="Submit" onclick="ajax();" />
And remove the action part in the form.
I jQuery you can use event.preventDefault(); otherwise just use return false;

Pointy is correct... just add a click handler to the submit button, however make sure the last line of the click handler returns "false" to prevent the form from actually being posted to the form's action.
<html>
<head>
<script type="text/javascript">
function ajax(){
//...
return false;
}
</script>
</head>
<body>
<form action="thispage.htm">
<!-- ... -->
<input type="submit" value="Submit" onclick="ajax();" />
</form>
</body>
</html>
