I have a form at the bottom of a long page, if a user fills out the form but it doesn't validate the page is reloaded in the typical codeigniter fashion:
$this->load->view('template',$data);
however because the form is way down at the bottom of the page I need the page to load down there like you do with HTML anchors. Does anyone know how to do this in codeigniter?
I can't use the codeigniter
redirect();
function because it loses the object and the validation errors are gone. Other frameworks I've used like Yii you can call the redirect function like:
$this->redirect();
which solves the problem because you keep the object. I've tried using:
$this->index()
within the controller which works fine as a redirect but the validation errors are in another method which is where the current page is loaded from:
$this->item($labs)
but when I use this it get stuck in a loop
Any ideas? I've seen this question a lot on the net but no clear answers. I'm researching using codeigniter "flash data" but think it's a bit overkill.
cheers.
I can't personally vouch for this, but according to this thread if you append the anchor to the form's action, it will work.
CodeIgniter helper:
<?php echo form_open('controller/function#anchor'); ?>
Or vanilla HTML:
<form method='post' action='controller/function#anchor'>
If you were open to using Javascript, you could easily detect a $validation_failed variable and appropriately scroll. Or, even better, use AJAX.
Another option is to put the form near the top of the page?
Ok, as far as I understood your problem, it isn't much related to the back end(codeigniter). You want the form at the bottom of the page to be 'what-users-sees-on-page-load' (since you mention anchors).
Now, what you can do is, you can set delimiters for your validation error messages using:
echo validation_errors('<div id="bottom_form_error">', '</div>');
Using jQuery ScrollTo, do:
$( function() { $('#bottom_form_error').ScrollTo(); } );
And, the user will be scrolled to the errors at the bottom of the page. Don't forget to include jQuery too.
Anchor hash fragment click is different - it is scrolling at ∞ speed.
I hope that is what you wanted.
P.S. I am ignoring what you said below this line:
Does anyone know how to do this in codeigniter?
as I felt it is not really relevant to the question.

Is it possible to remove a value whilst the page is loading?
I'm using OSClass, and on one of the pages it's by default adding a value for region (cambridshire):
I need to clear this value since it's causing problems, everytime I type something else in, by default, it registers it as Cambridgeshire...
If I look at code for it:
It's being generated by a function (can see my JQuery attempt to clear it which hasn't worked).
Then if I search the function is splits up in many different parts, so I don't know where to go from there.
Basically, is there a way to remove the value when page loads and save the new value when the user submits?
JSFiddle - Note it won't display anything due to the way code is generated
Have you tried removing <?php ItemForm::region_text(); ?> on it's own? Or passing an empty string <?php ItemForm::region_text(''); ?>
I'm not familiar with OSClass though I'm afraid.
Paste this code below the jQuery initialization:
$(document).ready(function(){
$("#region").val('');
})
I thought this would be really simple but obviously after a couple of days trial and no success I have to ask the people to help, looked everywhere.
right im basically creating a php template without much guidance on the foundation 4 framework with is a responsive framework. Now this framework is rather basic and so to add page transitions ive had to use jquery to do what i believe is an ajax call to take "content" from another page and display it on the template page index.html
for which I am currently using the following
<script>
$(document).ready(function() {
$('nav.top-bar > section.top-bar-section > ul.right > li > a').click(function() {
var toLoad = $(this).attr('href')+' #content';
$('#content').hide(1000,loadContent);
$('#load').remove();
$('#main_wrapper').append('<span id="load">LOADING...</span>');
$('#load').fadeIn('fast');
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-0);
function loadContent() {
$('#content').load(toLoad,showNewContent);
}
function showNewContent() {
$('#content').show(1000,hideLoader);
}
function hideLoader() {
$('#load').fadeOut('fast');
}
return false;
});
});
</script>
NOW before i changed over to using ajax and jquery i was operating the menu "active" class and the page name with a simple variable set on each page in the first line listed as $page='' and then the page name
now that im loading the content with ajax even if i include this variable in the content of the new page it will not update in either the or the menu title
im very sorry i dont write things correctly im new to this forum thing
thank you for the help in advance
:) I prefer someone to explain what i need to do and how to do it rather than just copy and pasting code as im a learner :)
You probably want to load the page and parse the result in jQuery to get the new page’s <title> tag and set the requesting page’s <title> tag.
The only thing I’d ask is: why are you doing this? Are you just wanting AJAX page navigation in your website instead of the traditional propagating navigation?
I am only able to answer one part of your question due to extreme confusion, so:
First off, here's why your url changes:
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-0);
You are modifying it with that line. That line, however, has an interesting little quirk:
attr('href').length-0
at the end. Why the -0? That would make no difference. I'd clean it up.
Outside of that, I'm incredibly confused with what you're asking so let me try rephrasing it and you can tell me what I'm missing.
You want to have a user click on a navigation link, and load that link's content via an AJAX call using jQuery, and then replace the content on the page with the newly loaded page, correct?
When you say "right on top main page i have variable $page = then the page name", what do you mean by "main page"? Do you mean it's a line of text in HTML? Part of a script that you haven't included here? Part of your PHP code?
And then you say "ive tried including the tag in a div that changes along with the above content"- what is "the tag"?
By reading this 4 or 5 times I could barely discern the above understanding of what you're trying to do.
Please make heavy edits to you question- it's incredibly hard to understand.
Lastly, why are you trying to replace the browser's functionality of a user clicking a link and loading content? That's what the browser is for. The browser also, conveniently, has a loading indicator in the url bar usually (or some form thereof), letting the user know the content is still loading.
function loadContent() {
$('#content').load(toLoad,showNewContent);
}
So first off, look at the jQuery doc for the load method:
http://api.jquery.com/load/
Your issue is that it is calling for three arguments, and you are passing two. If there are multiple arguments listed and you only want to pass SOME of them, you still need to supply a null value for the ones you want to "skip". Try changing your call to this:
function loadContent() {
$('#content').load(toLoad, null, showNewContent);
}
You'll notice that I'm passing "null". If that doesn't work, pass an empty string, like this:
function loadContent() {
$('#content').load(toLoad, "", showNewContent);
}
That second argument is data to be passed with the request. It's the THIRD argument that you list as your callback, which as far as I can tell is where you're making the mistake.
I am trying to load a specific portion of an article with using of jquery load() function when a tab is clicked. The tab is inside an article and trying to show another article within the first article from where the tab is being clicked. The jquery code I have put inside the template.php of choosen template. The main problem is that when I click nothing is comming inside the first article under the tab. I am using joomla2.5.11 version. Please give some suggestion.The jquery code what I am trying is shown below:
$(function(){
$("h3.menuheader").click(function(){
$(".active-tab").removeClass("active-tab");
$(this).addClass("active-tab");
$(".tabcontent-ul").slideUp();
$(".tabcontent").load("http://www.mpsinfoservices.com/projects/teamzstudio/web-application-development#link1",function(){
$(".tabcontent").slideToggle();
});
});
});
Unfortunately I don't think you've provided enough to diagnose this issue. But perhaps I can help with how I would diagnose.
To start with, try this instead:
// http://www.mpsinfoservices.com/projects/teamzstudio/web-application-development#link1
$(".tabcontent").load("http://www.google.co.uk",function(){
$(".tabcontent").slideToggle();
});
Then open up your developer tools and see if a call is being made to load that data.
If it is, then you need to consider that it might be loading the data and putting it in another element you can't see.
So to test, create a new container on the page near your footer, which you know will be visible with a specific #ID like <div id="testID"></div> and load into that. Once that is working, look to confirm your .tabcontent element is the one you want using something like console.log().
I have an index.php with two major sections: the navbar and the main-content. The navbar contains links which will load another webpage to the main-content through this jQuery code:
jQuery('#main-content').load('sampleurl');
Some of these web pages contain links to another web page, so I want to add a back button.
I tried using the history.back() and history.go(-1), as well as the $_SERVER['HTTP_REFERER'], but they don't really work in my case.
How will I add the back button in this situation?
You should keep your last viewed page in JavaScript variable or in value of hidden input and then you only need to add button with
jQuery('#main-content').load(old_url);
You must always update your variable when you load your next page via jQuery('#main-content').load('sampleurl');
Try manipulating the javascript location or location.hash
https://developer.mozilla.org/en-US/docs/DOM/window.location
Of course, you need to be able to turn your URL back into the relevant page content too.
In conjunction with both Charlie and Michael's answers, since you are already using jQuery, another option is to include the jQuery Address plugin.
You can implement this idea, by creating a function to read a hash path to load new content. Following this, the content can be navigated by the built-in back + forward buttons.
The only challenge I foresee with this implementation is associating the new content with the hash path.
Good luck!
Just an idea: Add hash to Url whenever you load the page; and then you can use history.back()
$(function(){
if(window.location.hash === 'sampleurl'){
jQuery('#main-content').load('sampleurl', function(){
window.location.hash = 'sampleurl'; //<<-- match with your loaded page;
});
}
});
good luck !
I have a site that has voting on the front page node, and I need to update a view on the same node after each vote. I'm currently using the following code in my page.tpl.php
<script type="text/javascript">
function fivestarResult(voteResult) {
$('div#fivestar-summary-'+voteResult.vote.id).html(voteResult.result.summary);
window.location = "http://www.mydomain.com/";
};
</script>
Is there a way to directly refresh the view instead of refreshing the whole page? I'm not very good in javascript so I'm a little lost.
An idea i may do in this kind of situation is to Ajax call the view again and render it inside the page again via JQuery on click event.
take this example , i guess this will clarify more
Drupal 6: Render Views 2 data in a page tpl file
Thanks Rabe,
That sounds like it should work. I tried it a few different ways but couldn't get it to ...
Is there something obvious I could be missing from this code (in page.tpl.php)?
<script type="text/javascript">
function fivestarResult(voteResult) {
$('div#fivestar-summary-'+voteResult.vote.id).html(voteResult.result.summary);
<?php
$name = "comparison_view";
print views_embed_view($name, $display_id = 'default');
?>
};
</script>
Thanks a lot for the help
Like many things in Drupal, there may be a module already written to do this. Ajax views refresh sounds very promising!
I have spent countless hours debugging a view only to realize I had caching enabled and was looking at old results. The caches for different user groups are separate as well. So you may need to manually flush cache to get this to update, which might be a challenge with Ajax.
