I want to add a java-script to click a button when bottom of page is reached...the code for that is
<script>
function getScrollXY() {
var scrOfX = 0, scrOfY = 0;
if( typeof( window.pageYOffset ) == 'number' ) {
//Netscape compliant
scrOfY = window.pageYOffset;
scrOfX = window.pageXOffset;
} else if( document.body && ( document.body.scrollLeft || document.body.scrollTop ) ) {
//DOM compliant
scrOfY = document.body.scrollTop;
scrOfX = document.body.scrollLeft;
} else if( document.documentElement && ( document.documentElement.scrollLeft || document.documentElement.scrollTop ) ) {
//IE6 standards compliant mode
scrOfY = document.documentElement.scrollTop;
scrOfX = document.documentElement.scrollLeft;
}
return [ scrOfX, scrOfY ];
}
//taken from http://james.padolsey.com/javascript/get-document-height-cross-browser/
function getDocHeight() {
var D = document;
return Math.max(
D.body.scrollHeight, D.documentElement.scrollHeight,
D.body.offsetHeight, D.documentElement.offsetHeight,
D.body.clientHeight, D.documentElement.clientHeight
);
}
document.addEventListener("scroll", function (event) {
if (getDocHeight() == getScrollXY()[1] + window.innerHeight) {
document.getElementById('next').click()
}
});
</script>
the problem is that the button is SQLFORM's submit button, so my question is what is the id of SQLFORM submit button, or how can i define it..i have tried the following but with no success.
form2.custom.widget.submit_button['_id']='next'
it shows the error 'NoneType' object does not support item assignment.
there is a some excellent information on Custom CSS classes for SQLFORM widget input in web2py, but i still cant figure this out....
You can identify the submit button with a jQuery selector, such as "input[type=submit]" (or more specifically, "#submit_record__row input[type=submit]"). If you want to assign an ID, you can do:
form2.custom.submit['_id'] = 'next'
or:
form2.element('input[type=submit]')['_id'] = 'next'

I'm looking for hours for a solutions but can't find anything that works for me.. I am trying to create a button which will wrap a specific text with span which works fine.
Now i am trying to make it a toggle so i will be able to unwrap the span from the text but can't get it done..
Basically the button needs to work the same as the Italic button but i couldn't find its code anywhere in my files..
How can i determine if i'm on my requested node so i can deactivate?
How can i make it work as toggle as i mentioned above?
Here is my code-
ed.addButton ('remark', {
title : 'Remark Text',
image: url + '../../images/remark-icon.png',
onClick : function() {
var state = true;
ed.focus();
ed.controlManager.setActive('remark', state);
var text = ed.selection.getContent({format : 'text'});
var selected_elem = ed.selection.getNode(); // Get selected element
var elem_type = ed.selection.getNode().nodeName; // Get element type
selected_elem = jQuery(selected_elem ).attr('class'); // Get element's class
if( elem_type !== 'SPAN') {
ed.selection.setContent('<span class="remark-text">' + text + '</span>');
}
ed.on('NodeChange', function(e) {
state = true;
ed.controlManager.setActive('remark', state);
});
}
});
Thanks for any help!

In IE8 when i give min-height in vh then ie8 ignore it and not work.in other brower work well.some where i read that vh not support ie8 any solution that i use vh in ie8.
<div class=" item Finish " id="Finish" style="overflow: visible!important;" >
<div style="background-color: #27AE61!important;padding: 0px !important;min-height:85vh;overflow: visible!important;">
<-- html code -->
</div>
</div>
Silver Ringvee's answer is absolutely correct, except that default jQuery .css() functionality is broken when you want to do stuff like .css('margin-right') to get the right margin of an element. I found this issue when using fancyBox. I fixed that by checking if props is a string, if so parseProps($.extend({}, props)) is not used. I also added a check if multiple arguments were given, to support css('margin-right', '12px'). Here's my code:
(function ($, window) {
var $win = $(window), _css = $.fn.css;
function viewportToPixel(val) {
var vwh_match = val.match(/[vwh]+/);
var digits_match = val.match(/\d+/);
if (vwh_match && vwh_match.length && digits_match && digits_match.length) {
return (vwh_match[0] == 'vh' ? $win.height() : $win.width()) * (digits_match[0] / 100) + 'px';
}
return val;
}
function parseProps(props) {
var p, prop;
for (p in props) {
prop = props[p];
if (/[vwh]$/.test(prop)) {
props[p] = viewportToPixel(prop);
}
}
return props;
}
$.fn.css = function (props) {
var self = this,
originalArguments = arguments,
update = function () {
if (typeof props === 'string' || props instanceof String) {
if (originalArguments.length > 1) {
var argumentsObject = {};
argumentsObject[originalArguments[0]] = originalArguments[1];
return _css.call(self, parseProps($.extend({}, argumentsObject)));
} else {
return _css.call(self, props);
}
} else {
return _css.call(self, parseProps($.extend({}, props)));
}
};
$win.resize(update);
return update();
};
}(jQuery, window));
vw and vh units are supported by IE 9 and up.
Try this:
(function( $, window ){
var $win = $(window)
, _css = $.fn.css;
function viewportToPixel( val ) {
var percent = val.match(/\d+/)[0] / 100,
unit = val.match(/[vwh]+/)[0];
return (unit == 'vh' ? $win.height() : $win.width()) * percent + 'px';
}
function parseProps( props ) {
var p, prop;
for ( p in props ) {
prop = props[ p ];
if ( /[vwh]$/.test( prop ) ) {
props[ p ] = viewportToPixel( prop );
}
}
return props;
}
$.fn.css = function( props ) {
var self = this,
update = function() {
return _css.call( self, parseProps( $.extend( {}, props ) ) );
};
$win.resize( update );
return update();
};
}( jQuery, window ));
$('div').css({
height: '50vh',
width: '50vw',
marginTop: '25vh',
marginLeft: '25vw',
fontSize: '10vw'
});
Working demo: http://jsbin.com/izosuy/1/edit?js,output
Works well in IE8 as well!

How and Why does the polyfill can work?
w.matchMedia = w.matchMedia || (function( doc, undefined ) {
var bool,
docElem = doc.documentElement,
refNode = docElem.firstElementChild || docElem.firstChild,
// fakeBody required for <FF4 when executed in <head>
fakeBody = doc.createElement( "body" ),
div = doc.createElement( "div" );
div.id = "mq-test-1";
div.style.cssText = "position:absolute;top:-100em";
fakeBody.style.background = "none";
fakeBody.appendChild(div);
return function(q){
div.innerHTML = "<style media=\"" + q + "\"> #mq-test-1 { width: 42px; }</style>";
docElem.insertBefore( fakeBody, refNode );
bool = div.offsetWidth === 42;
docElem.removeChild( fakeBody );
return {
matches: bool,
media: q
};
};
}( w.document ));
paulirish alse implement it in another similar way, https://github.com/paulirish/matchMedia.js/blob/master/matchMedia.js
the key code is as following
info = ('getComputedStyle' in window) && window.getComputedStyle(style, null) || style.currentStyle;
styleMedia = {
matchMedium: function(media) {
var text = '#media ' + media + '{ #matchmediajs-test { width: 1px; } }';
// 'style.styleSheet' is used by IE <= 8 and 'style.textContent' for all other browsers
if (style.styleSheet) {
style.styleSheet.cssText = text;
} else {
style.textContent = text;
}
// Test if media query is true or false
return info.width === '1px';
}
};
Both work the same way.
They just inject the media that you pass as a parameter, and use it to aply a predefined style (a width of 42 px for the first, and of 1px for the second),
If the width of the element is really the predefined one, the media is working and the function evaluates to true
I am using file uploader from one of the plugin.
That php file called at file onchange event by ajax.
I got a file at php.
I can upload file manually by the help of this
$target_path = "../../../uploads/extension/";
$target_path = $target_path . basename( $_FILES['file']['name']);
if(move_uploaded_file($_FILES['file']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['file']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
But i want upload a file like other file uploading in Media. Its stored in uploads/2014/07 (i.e) upload/yearFolder/MonthFolder.
How to upload file like wise. I used wp_handle_upload(). but it returns undefined to call. So how to upload file.
Use the given steps

add this file in your header(like:<script type="text/javascript" src="<?php print get_stylesheet_directory_uri() ;?>/js/ajaxupload.3.5.js" ></script> )
Now place this code below it in header
<script type="text/javascript" >
jQuery(function(){
var btnUpload=jQuery('#upload');
var status=jQuery('#status');
new AjaxUpload(btnUpload, {
action: '<?php echo get_template_directory_uri();?>/upload-file.php',
name: 'uploadfile',
onSubmit: function(file, ext){
if (! (ext && /^(jpg|png|jpeg|gif)$/.test(ext))){
// extension is not allowed
status.text('Only JPG, PNG or GIF files are allowed');
return false;
}
//status.text('Uploading...');
status.html('<img style="float:right;position:absolute;right:-30px;top:10px" width="16" border="0" height="16" alt="" src="<?php echo get_template_directory_uri(); ?>/img/ajax-loader.gif" id="pleasewait">');
},
onComplete: function(file, response){
//alert(response);
//On completion clear the status
status.text('');
//Add uploaded file to list
if(response!='error'){
//jQuery('<li></li>').appendTo('#files').html('<img src="'+response+'" alt="" /><br />'+file).addClass('success');
jQuery('<li></li>').appendTo('#files').html(file).addClass('success');
jQuery('<input type="hidden" id="uploaded-pres" value="'+response+'"/>').appendTo('#files');
} else{
jQuery('<li></li>').appendTo('#files').text(file).addClass('error');
}
}
});
});
</script>
Now make a upload-file.php in root folder
<?php
include_once('../../../wp-load.php');
if ( ! function_exists( 'wp_handle_upload' ) ) require_once( ABSPATH . 'wp-admin/includes/file.php' );
$uploadedfile = $_FILES['uploadfile'];
$upload_overrides = array( 'test_form' => false );
$movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
if ( $movefile ) {
//echo "File is successfully uploaded.\n";
echo $movefile['url'];
} else {
echo "error";
}
?>
And lastly in html where you want to use upload button just put this
<div id="upload" ><span>Upload File<span></div><span id="status" ></span>
<ul id="files" ></ul>
Note: Its looking lengthy because i have written the js file code and php code at one place.
So arrange these file.
I want to improve the process of uploading pictures in a Real Estate Website. This website is running WordPress 3.8. The theme offers front end submission with a very simple interface. The user selects the images (one by one) and then clicks to add. Finally when the user submit the listing all the images are uploaded at once. This is the screenshot of how it looks: Original Option: Listing Images.
This is the JQuery Plugin I am currently using,
/*!
* jQuery imagesLoaded plugin v2.1.1
* http://github.com/desandro/imagesloaded
*
* MIT License. by Paul Irish et al.
*/
/*jshint curly: true, eqeqeq: true, noempty: true, strict: true, undef: true, browser: true */
/*global jQuery: false */
;(function($, undefined) {
'use strict';
// blank image data-uri bypasses webkit log warning (thx doug jones)
var BLANK = 'data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///ywAAAAAAQABAAACAUwAOw==';
$.fn.imagesLoaded = function( callback ) {
var $this = this,
deferred = $.isFunction($.Deferred) ? $.Deferred() : 0,
hasNotify = $.isFunction(deferred.notify),
$images = $this.find('img').add( $this.filter('img') ),
loaded = [],
proper = [],
broken = [];
// Register deferred callbacks
if ($.isPlainObject(callback)) {
$.each(callback, function (key, value) {
if (key === 'callback') {
callback = value;
} else if (deferred) {
deferred[key](value);
}
});
}
function doneLoading() {
var $proper = $(proper),
$broken = $(broken);
if ( deferred ) {
if ( broken.length ) {
deferred.reject( $images, $proper, $broken );
} else {
deferred.resolve( $images );
}
}
if ( $.isFunction( callback ) ) {
callback.call( $this, $images, $proper, $broken );
}
}
function imgLoadedHandler( event ) {
imgLoaded( event.target, event.type === 'error' );
}
function imgLoaded( img, isBroken ) {
// don't proceed if BLANK image, or image is already loaded
if ( img.src === BLANK || $.inArray( img, loaded ) !== -1 ) {
return;
}
// store element in loaded images array
loaded.push( img );
// keep track of broken and properly loaded images
if ( isBroken ) {
broken.push( img );
} else {
proper.push( img );
}
// cache image and its state for future calls
$.data( img, 'imagesLoaded', { isBroken: isBroken, src: img.src } );
// trigger deferred progress method if present
if ( hasNotify ) {
deferred.notifyWith( $(img), [ isBroken, $images, $(proper), $(broken) ] );
}
// call doneLoading and clean listeners if all images are loaded
if ( $images.length === loaded.length ) {
setTimeout( doneLoading );
$images.unbind( '.imagesLoaded', imgLoadedHandler );
}
}
// if no images, trigger immediately
if ( !$images.length ) {
doneLoading();
} else {
$images.bind( 'load.imagesLoaded error.imagesLoaded', imgLoadedHandler )
.each( function( i, el ) {
var src = el.src;
// find out if this image has been already checked for status
// if it was, and src has not changed, call imgLoaded on it
var cached = $.data( el, 'imagesLoaded' );
if ( cached && cached.src === src ) {
imgLoaded( el, cached.isBroken );
return;
}
// if complete is true and browser supports natural sizes, try
// to check for image status manually
if ( el.complete && el.naturalWidth !== undefined ) {
imgLoaded( el, el.naturalWidth === 0 || el.naturalHeight === 0 );
return;
}
// cached images don't fire load sometimes, so we reset src, but only when
// dealing with IE, or image is complete (loaded) and failed manual check
// webkit hack from http://groups.google.com/group/jquery-dev/browse_thread/thread/eee6ab7b2da50e1f
if ( el.readyState || el.complete ) {
el.src = BLANK;
el.src = src;
}
});
}
return deferred ? deferred.promise( $this ) : $this;
};
})(jQuery);
My goal is to have a more flexible system, where all the images can be selected at the same time and it starts loading right away. This will speed up the process and improve user experience. Also to arrange them in any order by moving them around. This is an example I found on another website. See screenshot: New Option: Multiple Image Upload
What programing language is good for this development? Any recommendations of where I can find code snippets for this application? Thanks in advance for your help!!
rough draft.....you need jquery and wordpress media js..just watch the js variable names below if there are errors it will be with these...
php in functions file:
if(function_exists( 'wp_enqueue_media' )){
wp_enqueue_media();
}
javascript...add to the page header..wp_enqueue_scripts or to your template (do this first to make sure its working!) you'll need your element called upload_image_button or change accordinely
// Uploading files
var media_uploader;
jQuery('.upload_image_button').live('click', function( event ){
var button = jQuery( this );
// If the media uploader already exists, reopen it.
if ( media_uploader ) {
media_uploader.open();
return;
}
// Create the media uploader.
media_uploader = wp.media.frames.media_uploader = wp.media({
title: button.data( 'uploader-title' ),
// Tell the modal to show only images.
library: {
type: 'image',
query: false
},
button: {
text: button.data( 'uploader-button-text' ),
},
multiple: button.data( 'uploader-allow-multiple' )
});
// Create a callback when the uploader is called
media_uploader.on( 'select', function() {
var selection = media_uploader.state().get('selection'),
input_name = button.data( 'input-name' ),
bucket = $( '#' + input_name + '-thumbnails');
selection.map( function( attachment ) {
attachment = attachment.toJSON();
// console.log(attachment);
bucket.append(function() {
return '<img src="'+attachment.sizes.thumbnail.url+'" width="'+attachment.sizes.thumbnail.width+'" height="'+attachment.sizes.thumbnail.height+'" class="submission_thumb thumbnail" /><input name="'+input_name+'[]" type="hidden" value="'+attachment.id+'" />'
});
});
});
// Open the uploader
media_uploader.open();
});
template file:
<span class="upload_image_button alt_button" data-input-name="images" data-uploader- title="Upload Images" data-uploader-button-text="Add to Submission" data-uploader-allow-multiple="true">Upload</span>
php $_POST return
if ( !empty( $_POST['submission_images'] ) ) {
// do something with the files, set featured img, add to content or save post_meta
}
or..............i came across a plugin that does this a lot better........sorry its in OOP and designed on back end but you can modify for front end! The problem with multi file uploader from WP is it required users to hit "CTRL" + click with no guidance....massive problem on front-end forms...this one you can add more guidance to easily...sorry i havent a frontend sample yet, i have yet to create :)
"Multi File Upload"
e.g.
public function render_meta_box_content($post)
{
// Add an nonce field so we can check for it later.
wp_nonce_field('miu_inner_custom_box', 'miu_inner_custom_box_nonce');
// Use get_post_meta to retrieve an existing value from the database.
$value = get_post_meta($post->ID, '_ad_images', true);
$metabox_content = '<div id="miu_images"></div><input type="button" onClick="addRow()" value="Add Image" class="button" />';
echo $metabox_content;
$images = unserialize($value);
$script = "<script>
itemsCount= 0;";
if (!empty($images))
{
foreach ($images as $image)
{
$script.="addRow('{$image}');";
}
}
$script .="</script>";
echo $script;
}
save function
public function save_image($post_id)
{
/*
* We need to verify this came from the our screen and with proper authorization,
* because save_post can be triggered at other times.
*/
// Check if our nonce is set.
if (!isset($_POST['miu_inner_custom_box_nonce']))
return $post_id;
$nonce = $_POST['miu_inner_custom_box_nonce'];
// Verify that the nonce is valid.
if (!wp_verify_nonce($nonce, 'miu_inner_custom_box'))
return $post_id;
// If this is an autosave, our form has not been submitted,
// so we don't want to do anything.
if (defined('DOING_AUTOSAVE') && DOING_AUTOSAVE)
return $post_id;
// Check the user's permissions.
if ('page' == $_POST['post_type'])
{
if (!current_user_can('edit_page', $post_id))
return $post_id;
} else
{
if (!current_user_can('edit_post', $post_id))
return $post_id;
}
/* OK, its safe for us to save the data now. */
// Validate user input.
$posted_images = $_POST['miu_images'];
$miu_images = array();
foreach ($posted_images as $image_url)
{
if(!empty ($image_url))
$miu_images[] = esc_url_raw($image_url);
}
// Update the miu_images meta field.
update_post_meta($post_id, '_ad_images', serialize($miu_images));
}
