I am trying to submit a form with a couple of different inputs, which all work fine. However, one of the inputs is a textarea (sort of). I had to alter it into a content editable div, mainly because I created my own bold, italic and underline buttons which wouldn't work with normal textareas. The problem is that the form on submit is not sending the text to the php and i was wondering what i could do to get the value of the div in the php.
Here is the "textarea":
<div id="dash_new_shout_textarea" name="dash_new_shout_textarea"
class="dash_new_shout_textarea" contenteditable="true"
placeholder="Write your shout..." name="dash_new_shout_textarea"
value="<?php echo isset($_POST['dash_new_shout_textarea']) ?
$_POST['dash_new_shout_textarea'] : '' ?>"></div>
The form is just a normal form with method=post.
Here is the php:
$newShoutTextarea = $_POST['dash_new_shout_textarea'];
Thanks for the help
I would suggest that you follow the other answers and use jQuery, but since there is no jQuery tag in your question I suppose that I should provide a good non-jQuery solution for you.
HTML
<form onsubmit="prepareDiv()">
<div id="dash_new_shout_textarea" class="dash_new_shout_textarea" contenteditable="true" placeholder="Write your shout..." name="dash_new_shout_textarea" value="<?php echo isset($_POST['dash_new_shout_textarea']) ? $_POST['dash_new_shout_textarea'] : '' ?>"></div>
<input type="hidden" id="dash_new_shout_textarea_hidden" name="dash_new_shout_textarea" />
</form>
Javascript
function prepareDiv() {
document.getElementById("dash_new_shout_textarea_hidden").value = document.getElementById("dash_new_shout_textarea").innerHTML;
}
Your PHP remains the same.
What you can do is this:
<div id="dash_new_shout_textarea"></div>
<input type="hidden" name="dash_new_shout_textarea" id="dash_new_shout_textarea_hidden" />
<script type="text/javascript">
setInterval(function () {
document.getElementById("dash_new_shout_textarea_hidden").value = document.getElementById("dash_new_shout_textarea").innerHTML;
}, 5);
</script>
the problem is that a DIV is not a form element and cannot be posted. If you use some javascript, you could populate a hidden input field with the data and then receive it server side as POST variable
You can add a hidden input to your form and update it with jquery
<div id="dash_new_shout_textarea" name="dash_new_shout_textarea"
class="dash_new_shout_textarea" contenteditable="true"
placeholder="Write your shout..." name="dash_new_shout_textarea"
value="></div>
<form id="target" method="post" action="destination.php">
<input id="textarea_hidden" name="textarea_hidden" type="hidden" value="">
<input type="submit" value="Submit">
</form>
script
$("#target").click(function() {
$("#textarea_hidden").val($("#dash_new_shout_textarea").val());
});
What you can do is use jQuery for this.
DEMO HERE
Proper scenario would be:
*Get value from div and save it into hidden field. *
This has to be done when you submit form:
$(function () {
$("#send").on("click", function () {
$("#hiddenfield").val($("#dash_new_shout_textarea").text());
alert($("#hiddenfield").val());
$("form#formID").submit();
});
});

JavaScript: Inline Script with SRC Attribute?
(3 answers)
Closed 6 years ago.
I tested my update.php file and it works perfect and there is not any error when i checked my script via console . Only problem in here . Ajax can't send values "id" "comment_area" to update.php file . What is the mistake in here ?
<script type="text/javascript" src="http://ajax.microsoft.com/ajax/jquery/jquery-1.6.2.min.js">
$(document).ready(function() {
$("#b_news").submit(function(evt) {
evt.preventDefault();
var text = $('#breaking_news_text').val();
var id = 21;
$.ajax({
type: "POST",
url: "update.php",
data: {
comment_area: text,
id: id
},
success: function() {
alert("sucess");
}
});
});
});
</script>
<form id="b_news" method="post" action="">
<div>
<div>
<textarea id="breaking_news_text" class="breaking_news_text" rows="6" cols="50" placeholder="Add text here..." required></textarea>
</div>
</div>
<div>
<input type="button" id="save" value="Save Changes" />
</div>
</form>
<?php
include("./inc/connect.inc.php");
$id=$_POST['id'];
$update = $_POST['comment_area'];
$sql = "update comments set comment_area='$update' Where id='$id'";
$result = mysqli_query($mysqli, $sql)or die("error");
?>
Seems to me that your button simply can't submit the form because of its type.
Try to change the type attribute of the button to submit this way :
<input type="submit" id="save" value="Save Changes"/>
You have two problems.
First you can only have one script per script element. The script can either be referenced by the src attribute or it can be between the start and end tags.
If you try to do both, as you are here, then only the src will be respected.
Use separate <script> elements for your two scripts.
Second, you have no way to trigger the submit event. The submit event will trigger when the form is submitted, but you can't do that from a textarea or a button. Replace the button with a submit button.
I have Created calculator project. I have only two pages. Now my question how to pass input field value to another page? trying too many ways its Not Working.
What to do to pass input fields values from one page to another page?
My input fields code Looks Like
<p class="pull-right">DPA Minimum Buyer Contribution<br /></p>
<div class="row">
<div class="col-md-3">
</div>
<div class="col-md-6" style="padding-right:1%">
<input type="text" id="txtLocationContactName5" class="txt"/>
</div>
<div class="col-md-3" style="padding-left:0%">
Another page name default_results.php I have created input fields
<div class="col-md-5 padding-rht">
Minimum Buyer Contribution
</div>
<div class="col-md-2 padding-Zero">
<input type="text" id="txtCustomerName3" class="txt" />
</div>
I have tired in jQuery script
<script>
$(function () {
$("#btnQueryString").bind("click", function () {
var url = "default_results.php?id=" + encodeURIComponent($("#txtLocationContactName5").val()) + "&technology=" + encodeURIComponent($("#txtCustomerName3").val());
window.location.href = url;
});
});
</script
but Not working so how to pass value one page to other page ?
You're making life hard for yourself! A simple form is needed to help you pass data to another page :). See here for info on html Forms - http://www.w3schools.com/html/html_forms.asp
Here is a simple example for you:
<form action="page_2_link" method="POST">
<input type="text" name="field1" value="easy">
<input type="submit" name="button1" value="Submit">
</form>
Then on the second page you can do this to retrieve the form data:
<?php
$blah = $_POST['field1']; // this now has the posted fields value
?>
I have given the second page answer in PHP as you have used this as a tag for this question, so I hope you are using this or my answer won't work.
I am new to Jquery and struggling to retrieve date values from my 'span' element in my jquery code and want to post it along with my form using java script.The reason i need to use this approach is that I am trying to use date range picker provided at http://www.dangrossman.info/2012/08/20/a-date-range-picker-for-twitter-bootstrap/
I have no idea how can i embed my span element value to my form and post it other page along with other form data.
Javscript
<script type="text/javascript">
document.getElementById("btnsubmit").addEventListener("click", function () {
var s;
s=jQuery.data($('aname'),s);
alert(s);
document.form.submit();
});
</script>
FORM:
-
<b class="caret"></b>
<span><?php echo date("F j, Y", strtotime('-30 day')); ?> - <?php echo date("F j, Y"); ?> </span>
</div>
<button id="btnsubmit" onclick="document.getElementById('frmdate').submit();">submit</button>
</form>
All i want to retrieve value of date from span element and post it along with form to retrieve it on next page to filter records from database based on this value.I would appreciate if anybody could help me in this regard.Thanks
As i suggested in the fiddle:
<form action="#">
<b class="caret"></b>
<span>14-10-2014</span>
<input type="hidden" name="tt" value="10-10-2014" />
<input id="tt2"/>
<input type="submit"/>
submit
<form>
And for the java script:
$(document).on('click', '#submit', function(event) {
event.preventDefault();
alert($("input[name='tt']").val()+" - Method 1");
$("#tt2").val($("span").text());
});
$(document).on('submit', 'form', function(event) {
event.preventDefault();
alert($("input[name='tt']").val() + " - Method 2");
$("#tt2").val($("span").text());
});
Don't forget to add the Jquery script.
(In the edit i've included the copy from the span)
Best regards
I think you haven't followed your tutorial properly.
Here is some code from the tutorial, and you will notice it puts the data into an INPUT field which will then be automatically sent as the form data, no added jQuery needed.
<form id="frmdate">
<div class="form-group">
<label for="reservation">Reservation dates:</label>
<div class="controls">
<div class="input-group">
<span class="input-group-addon"><i class="fa fa-calendar"></i></span>
<input type="text" name="reservation" id="reservation" />
</div>
</div>
</div>
</form>
<script type="text/javascript">
$(document).ready(function() {
$('#reservation').daterangepicker();
});
</script>
Also in your code you've mixed jQuery and standard javascript badly.
For one you're listening for a click of the button rather than the submit of the form, this means your code will never execute if a enter hits Enter key and it submits the form without clicking the button. Moreover this is bad practice for that reasons alone (and many other reasons)
Here is a cleaned up version of your code:
<form id="frmdate">
...
<b class="caret"></b>
<span id="aname"><?php echo date("F j, Y", strtotime('-30 day')); ?> - <?php echo date("F j, Y"); ?></span>
<button id="btnsubmit" type="sumbit">Submit</button>
</form>
<script type="text/javascript">
$(document).ready(function() {
$('#frmdate').submit(function(){
// Do some code here.
});
});
</script>
This function doesn't get the ID or class (first line), so the code is applied to all the fieldsets. For me that's not a big problem, but I would like to focuse the code on two specific IDs to make the code more compatible for plugins.
$('#feedburner_widget').ready(function() {
$('input').focus(
function(){
$(this).closest('fieldset').addClass('fieldset change-fieldset');
});
$('input').blur(
function(){
$(this).closest('fieldset').removeClass('change-fieldset');
});
});
Basically, this code adds a class to a fieldset when the user clicks on the input field. The ID is on the first line, but the code applies the effect to all the fieldsets. And it works exactly in the same way if I change '#feedburner_widget' to document. What I'm doing wrong? Thanks.
Edit: And this is the HTML code:
<form id="feedburner_widget" action="http://feedburner.google.com/fb/a/mailverify" method="post" target="popupwindow" onsubmit="window.open('http://feedburner.google.com/fb/a/mailverify?uri=<?php echo esc_attr($user); ?>', 'popupwindow', 'scrollbars=yes,width=550,height=520');return true">
<fieldset >
<input type="text" class="field" name="email" placeholder="<?php echo esc_attr($text); ?>" />
<input type="hidden" value="<?php echo esc_attr($user); ?>" name="uri" />
<input type="hidden" name="loc" value="<?php bloginfo('language'); ?>"/>
<span>
<input type="submit" value="" />
</span>
</fieldset>
</form>
When you do $('input'), you are asking jQuery to do a global search in the whole document. It does not 'remember' that you have just fetched the #feedburner element.
To search for only the elements in the #feedburner element, you could use the find() function on the jQuery object, like this:
$(document).ready(function() {
var $inputs = $('#feedburner_widget').find('input');
$inputs.focus(function(){
$(this).closest('fieldset').addClass('fieldset change-fieldset');
});
$inputs.blur(function(){
$(this).closest('fieldset').removeClass('change-fieldset');
});
});
In this particular case, you could also just alter the CSS selector to search directly for inputs inside the #feedburner_widget like this: $('#feeburner_widget input') If that element was already in a variable in your code, however, you should use the find method.
I have a small admin panel that I have created to do simple database tasks for my DayZ server. Now I want to make a simple editor for the news blurb on my website. The news blurb is stored in a table on my database. What I want is when the page loads it simply echo's the data and looks like it does on the live site. Then, when I click on it, I want it to convert into:
<textarea name="edit><?php echo news; ?></textarea>
This is my current code:
function divClicked() {
var divHtml = $(this).html();
var editableText = $("<textarea name="edit" />");
editableText.val(divHtml);
$(this).replaceWith(editableText);
editableText.focus();
// setup the blur event for this new textarea
editableText.blur(editableTextBlurred);
}
$(document).ready(function() {
$("#editable").click(divClicked);
});
<form method="post" action="newsedit.php">
<div id="editable"><?php echo $news; ?></div>
<input type="submit" value="Edit News" />
</form>
Now, this does work in the sense that when I click on the text it does convert into a textarea. The problem is that it doesn't give it the "edit" name so when I hit the sumbit button, it is as if I submitted nothing and it deletes all the data out of the table because
<textarea name="edit"></textarea>
is technically empty. Are there any ways to make it so when I click on the text it will convert the code to textarea with that specific name so there is actual data when I hit submit?
Change the form to:
<form method="post" action="newsedit.php">
<div id="<?php echo $newsID;?>"><?php echo nl2br($news); ?></div>
<input type="submit" value="Edit News" />
</form>
Where $newsID is returned along with the $news text.
The nl2br($news) will just make sure the line breaks are honored.
var editableText = $("<textarea name='edit' />");
http://jsfiddle.net/H5aM4/ inspect the textarea
TRY This
$("#editable").click( function(){
$(this).replaceWith(function() {
return $("<textarea name='edit'>").text(this.innerHTML);
});
});
Here is the working example
