For the last few days I am wandering arround the web for a script which would have the elementss I wish for.. The best thusfar is this one http://www.queness.com/post/328/a-simple-ajax-driven-website-with-jqueryphp, but there are a lot problems, where i need better solution:
I want no hashtags: I want all links for loading pages like folder (www.site.com/first/site/). This works magicaly on github (click here https://github.com/spjoe/deluge-yarss-plugin, and click on a random file and go back while watching adress bar). If someone knew what or how are they doing it would be really cool.
I need dynamic content: The script above only loads "cases" from switch function, while I need the php to check the url and find a file in mysql database and echo out content from desired tables based on the url, if it is found in the db ofcourse (if I point a link to site.com/harvey the php should find Harvey in the db and display for example his phone, adress and other details, while this must not be preloaded but requested only on click due to bandwight issues).
History: I would like to have an option where back and forward movements on the site would work flawlessly and with the animation as it works while clicking links..
Working links inside changable div: Because there is a problem with some scripts which don't change content where the link is inside it (for example first content box includes navigation, which should be replaced with different navigation in the second box), again this work very well with github..
I hope you give me some links or even more help with some code..
I think the script you are looking for is pjax, it has exactly all the features you want. You can find it on github: https://github.com/defunkt/jquery-pjax/tree/heroku
EDIT
You can use it with any server-side language you like. For example,
<script src="jquery.js"></script>
<script src="jquery.cookie.js"></script>
<script src="jquery.pjax.js"></script>
<script type="text/javascript">
$(function(){
$('nav a').pjax('#content')
})
</script>
in your website's head,
<nav>
<a href="otherContent1.php" >click me for other content</a>
<a href="otherContent2.php" >click me for even more additional content</a>
</nav>
<section id="content">
<h1>Original Content</h2>
<p>
this will be replaced by pjax with the content's of otherContent1.php or otherContent2.php
</p>
</section>
in your main template and modify your php code so that it looks for the HTTP_X_PJAX header. If it's present (see xhr.setRequestHeader('X-PJAX', 'true')) render only the part that should replace the contents of <section id="content">, else render the whole page. Pjax is then intelligent enough that if it works, it will replace only the contents of <section id="content">, and if it doesn't work, you still have regular links working. pjax will even take care of google analytics, if you're using it, so your tracking is still working.
EDIT2: Example
Ok, here you have a sample php page. be aware that I did not test this, i just wrote it quick and dirty here on stack overflow to show how you could solve this. This code is untested and certainly not production ready. But as an example, you could do something like this (the file should be named index.php):
<?php
$render_template=true;
if ($_SERVER["HTTP_X_PJAX"])
{
$render_template=false;
}
?>
<?php
if ($render_template) {
?>
<html>
<head>
<meta charset="utf-8" />
<title>Testing Pjax</title>
<script src="jquery.js"></script>
<script src="jquery.cookie.js"></script>
<script src="jquery.pjax.js"></script>
<script type="text/javascript">
$(function(){
$('nav a').pjax('#content')
})
</script>
</head>
<body>
Date in template: <?php echo $today = date("D M j G:i:s T Y"); ?>
<nav>
<a href="index.php?content=1" >click me for other content</a>
<a href="index.php?content=2" >click me for even more additional content</a>
</nav>
<section id="content">
<?php
}
?>
<?php
if ($_Get["content"]==1)
{
?>
<h1>Content=1</h1>
Date in content: <?php echo $today = date("D M j G:i:s T Y"); ?>
<p>
this will be replaced by pjax with the content's of index.php?content=1 or index.php?content=2
</p>
<?php
} else {
?>
<h1>Content 2=2</h1>
Date in content: <?php echo $today = date("D M j G:i:s T Y"); ?>
<p>
this will be replaced by pjax with the content's of index.php?content=1 or index.php?content=2
</p>
<?php
}
?>
<?php
if ($render_template) {
?>
</section>
</body>
</html>
<?php
}
?>
If you want the URL to display the "Correct" url when you ajax a page request you can use PJAX it changes the history with pushState but it doesn't work on ie6-ie9 check out CanIUse: History for compatibility issues.

I wonder how can I remove footer option saying "Your are using Open Source POS Version blah blah". I've already tried to edit files but after saving and restarting server UI get blocked. that means we can't change in footer. is there anyway to edit this option without blocking UI?
Please Just add this in application/views/partial/header.php
<script type="text/javascript">
$(document).ready(function() {
$('.blockUI').remove();
});
</script>
Problem Solved :)
The footer signature "You are using Open Source Point Of Sale" with version, hash and link to the original distribution of the code MUST BE RETAINED, MUST BE VISIBLE IN EVERY PAGE and CANNOT BE MODIFIED.
Better leave it as it is. Someone went through a lot of trouble making it work, and lets you use it for free. Donate instead of altering stuff you are not supposed to touch.
Its against the license terms to remove the footer. It is always professional and to credit someone's work and effort. Anyway you just need to open application/views/partial/footer.php and remove the following code:
<div id="footer">
<div class="jumbotron push-spaces">
<strong><?php echo $this->lang->line('common_you_are_using_ospos'); ?>
<?php echo $this->config->item('application_version'); ?> - <?php echo substr($this->config->item('commit_sha1'), 0, 6); ?></strong>.
<?php echo $this->lang->line('common_please_visit_my'); ?>
<?php echo $this->lang->line('common_website'); ?>
<?php echo $this->lang->line('common_learn_about_project'); ?>
</div>
</div>
My website has two div columns: a vertical navigation menu and main content. I used php to navigate different pages of my website to the main div (similar to this php example)...(eg. index.php?pg=about_us --> get content from /page/about.html). But one of the pages I want to display this gallery (http://sye.dk/sfpg/) on the main div.
How to display my gallery correctly in the main div (installed under /pages/gallery/index.php) (eg. width about 700px)? I have the same problem if the navigation menu is pointed to an external website. (let's say google) The size and charset are not displayed correctly while using div. Thank you.
<?php
// ...blah blah blah
$pgname = isset($_GET['pg']) ? trim(strip_tags($_GET['pg'])) : 'index';
//....
?>
// starts html, header and body
<div class="left_col">
<nav id="navigation">
<ul>
<li>Home</li>
<li>News</li>
<li>Gallery</li>
<li>Donate</li>
<li>About Us</li>
</ul>
</nav>
</div>
<section class="main_col clearfix">
<?php
if ($pgname != 'gallery'){
echo file_get_contents('pages/'. $pgname. '.html');
} else {
echo file_get_contents('http://google.com/'); // this doesn't work, and neither work with '/pages/gallery/index.php'
}
?>
</section>
Simplified, the above becomes:
gallery.php:
<?php
$name = 'gallery'; // Fixed for this example.
$html_gallery = 'pages/'. $name . '.html';
?>
<html>
<section>
<?php include $html_gallery ?>
</section>
</html>
pages/gallery.html:
<img src="/images/foo.jpg">
<img src="/images/bar.jpg">
<img src="/images/baz.jpg">
gallery.php would render much like this:
<html>
<section>
<img src="/images/foo.jpg">
<img src="/images/bar.jpg">
<img src="/images/baz.jpg">
</section>
</html>
So as you can see, it is up to you to style the output.
I like your idea a lot... but I think it would be much easier for you to use JavaScript and AJAX for this. Also, this approach will prevent the page from reloading!
EDIT - So, if you say you have both HTML and PHP files to use, an ext parameter (extension) in your events will do the trick. - EDIT
My idea would be to give an onclick event on each li calling a JavaScript function, let's say onclick="getContent(page, ext)". So of course you need to replace page to whatever string you like, let's say gallery; and ext to any extension you need as a string, let's say php.
Sample result:
<li onclick="getContent('news', 'html')" title="News">News</li>
<li onclick="getContent('gallery', 'php')" title="Gallery">Gallery</li>
Now, let's build our JavaScript-AJAX stuff. What we first need to do is create the function and place it right after the <body> tag inside a <script> tag, of course. Then remember to add an id to your main column, in the following example it will be content.
<script type="text/javascript">
function getContent(pageName, ext){
var url = "pages/"+pageName+"."+ext, // gallery.php - news.html
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function(){
if (xhttp.readyState == 4 && xhttp.status == 200) {
document.getElementById("content").innerHTML = xhttp.responseText;
}
};
xhttp.open("GET", url, true);
xhttp.send();
}
</script>
So now this function creates the request and gets the data from your URL and then places all the HTML in it inside your section. Of course, make sure that the HTML file contains only what you need inside the section.
Your main column in HTML should look like this:
<section class="main_col clearfix" id="content"></section>
- EDIT -
About the pre-made single file PHP gallery and resizing problem... I saw the demo and I think I know how it works... my advice is to make sure you set a width to your main_col section because the content given by the demo seems to be lots of div's with a class thumbbox which happens to be arranged by CSS display:inline-block so it should just work fine like that.
But the biggest problem I see is that once you load the content on your page, it will not work unless you include(); (PHP) the file or at least the source code for your single page PHP gallery, because you will only load the HTML and I also see that it uses the JavaScript onclick event just like my idea.
What I can say is that to help you solve this thing entirely, I should be able to see how you're implementing this library and many other things. I think you can work it out tho if you include the file like I said (so that the PHP code loads and hopefully prints the necessary JavaScript).
Also, the charset might be solved using PHP utf8_encode(); or utf8_decode();. Use the first one to encode from ISO-8859-1 to UTF8 and the second one for the other way round.
I have a series of pages that load a navbar from an external HTML file like so:
<head>
<script>
$(function() {
$("#navbar").load("navbar.html");
});
</script>
</head>
<body>
<div id="navbar"></div>
<!--other stuff here-->
This is all in a PHP page. However, there's part of that navbar that I want to set to set to a PHP $_SESSION variable (a username). Is there a way to easily do this?
Consider change navbar.html to navbar.php, then replace the username part by:
<?php echo($_SESSION["username"] ?>
then
$("#navbar").load("navbar.php");
You won't be able to do it in the HTML you are including of course, but you could echo it out in your PHP page in a known element:
<span class='echoedUsername'><?php echo($_SESSION["username"] ?></span>
and then apply it to an element in your navbar:
$("#navbar .username").text($('.echoedUsername').text())
For most of my projects I make an administration interface, which has the same design for every project. The design of the header, the footer, the topbar, the leftmenu, the css, etc. are always the same. It is a pity to create the views every time; so I was thinking: maybe there would be a nice way to put the admin interface in my MVC library, as it is reused by every project?
But for the moment, in every single view I got code like the following:
<?php $this->_include('/includes/doctype.php'); ?>
<head>
<?php $this->_include('/includes/head.php'); ?>
<title>Some title</title>
</head>
<body>
<?php $this->_include('/includes/topbar.php'); ?>
<div id="page">
<?php $this->_include('/includes/header.php'); ?>
<?php $this->_include('/includes/leftmenu.php'); ?>
<div id="content" role="main">
<h1>Some title</h1>
<p>Blah blah blah.</p>
</div><!-- /#content -->
<?php $this->_include('/includes/footer.php'); ?>
</div><!-- /#page -->
</body>
</html>
Would it be a good idea to extract the custom content from the structure of the interface, and put that structure in my library somehow to make it reusable?
After that how will it be possible to customize the title and the actual menus?
I do this all the time. I have a custom header and footer file that are called at the start and end of every page.
<?PHP
Require("includes/header.php");
...
Require("includes/footer.php");
?>
The header provides a database handle, a datetime string and handles logon, priveleges, logging of pageviews etc.
The footer provides a standard HTML page but includes some systematised variables. It also generates the menu dynamically from the driving database then closes the database connection.
This way when I write code, I don't get mixed up in the HTML and any bugs are easy to find.
I like variables akin to:
$display_scripts - adds extra data in the head section.
$display_onload_scripts - adds onload scripts to body section.
$display_style_sheets - option to include link to additional stylesheets
$display_above_menu - will appear above the menubar. NOT recommended.
$display_below_menu - will appear immediately below the menubar.
$display_one_column - page contents when only one column is to be used
$display_left_column - page contents when two columns used. Left pane.
$display_right_column - page contents when two columns used. Right pane.
$display_footer - appears in footer division.
My main code then just has to generate the appropriate variable. Fundamentally, what you need to do is examine the source of a good age you have produced then replace the stuff you want to change with variables.
Here is a schematised version of the file I use (pseudocode) to give you an idea of how I do it.
// Code here generates the menu from database
// Code here genereates popup alert messages from other users
//permanent links to external style sheets go here.
//You can also select skins here.
<?PHP
echo $display_style_sheets;
echo "<title>".$display_page_title."</title>";
?>
<script type="text/javascript" src="JAVASCRIPT GOES HERE.js"></script>
</head>
<body <?PHP echo $display_onload_scripts;?> >
<div id="page_area" >
<div id="banner">
</div>
<?php
echo $display_above_menu;
if(!$hide_menu){echo $display_menu;} //Insert the menu variable here.
echo $display_below_menu;
?>
<div id="content_area">
<div id="inner_content">
<?PHP
if($display_number_of_columns==1)
{
echo "<div id='onecolumn'>".$display_one_column."</div>"; //I only use this one
}
if($display_number_of_columns==2)
{
echo "<div id='leftcolumn'>".$display_left_column."</div>"; //these are left for legacy support from before I got better at CSS.
echo "<div id='rightcolumn'>".$display_right_column."</div>";
}
echo "<div id='footer'>".$display_footer."</div>"; //just in case - I hardly use it.
echo $display_pop_box; //for user alert messages to other users
?>
</div>
</div>
</div>
<div id="logbox"> Automatic Logout statement</div> //this is called by JS to activate timeouts.
</body>
</html>
<?PHP
$mysqlidb->close();
?>
Sorry it's such a lot of code. The layout allows easy adaptation and makes it simple to find the offending variable if things are not going as expected. There are more elegant solutions but this works well for me and is very fast.
I am trying to hide a comment form on my wordpress blog (although the page isn't the wordpress blog, I just get the posts).
If I have comments then the hide/show will work for the form and for the comments. If I have no comments the function doesn't work and i'm not sure why.
If anybody can help I can upload the php files that show the posts (blog.php) and the comments page (comments.php) that is generated within the wordpress theme.
EDIT: PHP code removed as not relevant to error. Relevant HTML code as follows:
...
<body class="home blog logged-in custom-background">
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery("#content img").addClass("imageSeven");
});
</script>
...
<a id="replytitle" href="javascript:togglecommentform('replyform17');">Show Comment Form</a>
<div id="replyform17" style="display:block;">
...
</div>
...
<a id="replytitle" href="javascript:togglecommentform('replyform6');">Show Comment Form</a>
<div id="replyform6" style="display:block;">
...
</div>
...
You have a problem, in that the output (view source) has a reference to jQuery right at the top:
<body class="home blog logged-in custom-background">
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery("#content img").addClass("imageSeven");
});
</script>
Some points on this:
Because you don't include a reference to jQuery anywhere - this will cause an error, meaning that even if the rest of you JavaScript is valid, it will fail to run.
You don't need jQuery(document).ready... if you move all your JavaScript to the bottom of the page (just before the </body> end tag.)
Your main problem seems to be a confused code structure. Based on the messy code you have (no offense), I would recommend using a library like jQuery:
Step 1: Remove all the JavaScript you have in that page.
By the looks of things, that just means the <script> block thats right beneath your <body> tag.
Step 2: Replace these <a> start tags:
<a id="replytitle" href="javascript:togglecommentform('replyform17');">
<a id="replytitle" href="javascript:togglecommentform('replyform6');">
With these:
<a id="replytitle17" href="#">
<a id="replytitle6" href="#">
Step 3: Just before the </body> tag, include the following:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script>
var images = $('#content img');
if (images.length > 0) { images.addClass("imageSeven"); }
$('#replytitle17').click(function() { $('#replyform17').toggle(); });
$('#replytitle6').click(function() { $('#replyform6').toggle(); });
</script>
This should achieve everything your page has, in jQuery.
