I have a Website with 2 pages and therefore I have 2 buttons to switch the page.
I want to change the Website only if it´s needed, so for example If I´m using page 1 and I click the button for page 1 it shouldn´t reload.
The first step I guess is to check the URL
$link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
but with research i couldn´t go further :/
Has anyone a idea how I can do that - it´s not important for me to use tag.
You can do something like this:
<button onclick="switchPage(this)" data-page="index.php">page 1</button>
<button onclick="switchPage(this)" data-page="test.php">page 2</button>
In order to redirect to the desired page, you can simply check the URL and the button pressed using JavaScript or jQuery.
Here is an example using JavaScript :
function switchPage(page) {
let pageName = page.dataset.page;
let path = location.href.split("/").slice(-1);
if(pageName != path) {
window.location.href=pageName;
}
}

I have a iFrame inside an php page.
The iFrame contains form (in asp), can I link a button outside the iFrame to the button outside?
Thanks!
you can use a button on main page to click a button on iframe page using jquery.
for example in main page if you have:
Main page HTML Sample:
<button id="parentbutton">click me</button>
<iframe name='select_frame' src='http://www.barzegari.com/DEAFULT.ASP'></iframe>
JQUERY in main page:
$("#parentbutton").click(function(){
$('input:button[name=save]').click(function() {
$('iframe[name=select_frame]').contents().find('#mybuttonid').click();
});
});
in iframe html:
you have a button with id(clientid) like "mybuttonid";
this is prevent by cross domain privacy, but you can do it by this way,
in your php page, use file_get_contents to get asp content, filter get form script and paste to php page, by this way, you can do everything as you want :)
Accessing iframe content from other URL will give you the error Refused to display 'YOUR_URL' in a frame because it set 'X-Frame-Options' to 'sameorigin'. This is because, all the server restricts the access of iframe content from third party website for security purpose. If you are not getting the above error, try the below code in your PHP file.
$("#phpbutton").click(function(){
var iframe = $('#aspiframe').contents();
iframe.find("#aspbutton").click();
});
<iframe id='aspiframe' src='YOUR_ASP_URL'></iframe>
<input type="button" id="phpbutton">click here</button>
Note : Make sure you have replaced with correct IDs.
I made a Modal Dialog that opens when you click the link
Edit Name
So after clicking that link the modal appears but the problem is that I don't know how to pass a usr variable for me to extract while at the same time opening the id called #modalDialog, something like this:
Edit Name
This other method redirects the page and opens the id, but the point is that I'm trying to avoid refreshing or redirecting to other pages just to edit a simple name, it goes like this:
Edit Name
I would to say thanks in advance!
I think you will want to use a data-* attribute within the anchor. Then access it using Javascript or JQuery.
<a href="#modalDialog" data-itemid="1" class="edit-name-link" >Edit Name</a>
Then in JQuery
$(".edit-name-link").click(
function()
{
var itemid = $(this).attr("data-itemid"); // this will get the clicked itemid
//now open your modal however you opened it before, and do something with itemid
});
I have listed projects in main work page, If i click on the project it will direct to work page where details have been displayed,If i click on the back button its is redirecting main work page.I want back button should redirect the previous project please help.
For your back button to redirect you to the previous project, you need to change the present HTML from
BACK
to :
BACK
You will have to do this dynamically by calculating the page numbers in the href as $_GET['page'] - 1
<? $page = (int) $_GET['page']; $back = $_GET['page'] - 1;
print 'BACK';
?>
The back button in my browser is working as-designed on your site: it takes me to the previous webpage I was on.
Websites cannot (easily) alter the behaviour of the browser back button in order to keep the user in-control. You can't (easily) use the back button to navigate through a website (if I understand your question correctly).
why not change the back button client-side?
<a href='#' id='backBtn'>Back</a>
And in JS:
document.getElementById('backBtn').onclick = function()
{
history.back();
};
If all you want is for the back btn to behave like the browser back button?
i have simple coding problem. i have created a page with textbox and share button. the page also contains one Points up button.
i had a problem with that points up button that when the user click on that button and refresh the page ... a window ask for resend of information
for that i have used following code which works fine.
`header('Location: samepageurl.php');
exit;`
but the problem with above code is when user scroll down page and click the button. the page automatically scrolls up. and user have to manually scroll it down.
what i want is the page should refresh but it should be on the same location where it was.
if the problem is still unclear please refer the following images
You can set a fragment identifier.
eg:
<a name="points_up"></a> <!-- this needs to be near that button, the page will scroll exactly where the element is -->
and redirect him to:
header('Location: samepageurl.php#points_up');
die;
Mihai answer is correct, but as you said that fragment identifier is not working because each user has points up button, you can pass user id as a fragment identifier and make a hidden(display : none;) <a> tag and pass the user id in front of each user...
Like this:
You can set a prefix before a user id too (optional)
<a name="pu12345" style="display: none;"></a>
<?php
header('Location: whatever.php#pu12345');
exit;
?>
You can send the request via ajax instead relying on the normal form submission. That will not affect the scrolling of the current page.
Add this line at the bottom of your page before the the <\body> tag
<button id="PageRefresh">Refresh a Page in jQuery</button>
<script type="text/javascript">
$('#PageRefresh').click(function() {
location.reload();
});
</script>
I've got a bit of a dilemma with some PHP code. The site I'm working on has a "Back to Previous Page" option and I'd like it to behave much like a browser's back button. As it stands right now, I'm using a $_SESSION variable to track what the current and previous pages are. I've also "refresh-proofed" the variables so that I don't end up with both the previous and current pages being the same.
So here's the issue:
With the current implementation, if I go to one page, say "register.php" and then go to "forgot.php", the previous page will be "register.php" which is fine. However, if I click "Back to Previous Page" I'll end up back at "register.php" with the previous page being "forgot.php" which now leaves me with a 2-page loop with going back.
I tried implementing SplQueue to help me keep track of variables and I tried using the dequeue() function in my links to get the last page to show up as the link. The problem comes in when the dequeue is actually called and causes the element to disappear so that if I refresh, the element is no longer in the queue and the link changes. I fixed this by "refresh-proofing" the function that calls the dequeue for me and it works as I would like it to. The problem is now forward-linking. If I direct myself to another page, I don't want the old links to dequeue information.
Ex:
I'm on register.php and my previous page is "forgot.php". The "Back to Previous Page" link accurately shows that "forgot.php" is the page it will direct to, but now it's no longer in the queue, so if I go to another page, say "profile.php" and then use the back button to go back to "register.php", it will no longer show "forgot.php" as the page that you will go to if you hit "Back to Previous Page" again.
So, I guess my question is really how I can make a link call a PHP function without actually calling that function UNTIL the link has been clicked. I've tried having the link point to a JavaScript function, but the JS functions tend to tell me that my queue is empty, which is completely wrong.
As a side note, the pages are a mix of HTML and PHP. The HTML is supplied to me and I've been adding the PHP in to add functionality to fields and to get data from a database. I have no problem using PHP to echo the HTML links if I have to, and if it can be done in HTML with a small <?php someCode(); ?>, that's fine too.
I thank you for your time to try and help me out.
EDIT:
So to try and clarify a bit, I have a structure that is currently tracking pages that the user has already been to as they visit them. It creates a mini history of the pages. My issue is that I have code like this:
Back To Previous Page
And I don't know what "somelink" is since it will change depending on your history. I know I can do something like:
Back To Previous Page
If I do anything like the above, the function is executed as the page is being displayed, so it makes it difficult to use an array_pop() or a dequeue() but again, the PHP will be executed as soon as the page is displayed. What I'm looking for is a way to display the link and then remove it from the history if and only if the "Back to Previous Page" link is clicked. As of right now, I'm storing an array in $_SESSION as was suggested below and since it's an array, I can show the last element in the array as the link, so the only real problem is to find a way to remove elements from the array when the link is clicked.
EDIT 2:
I've been scouring the internet and decided upon using JavaScript with AJAX to call a PHP file. This allows me to us an onClick on the links I have so that I can control when I array_pop from my $_SESSION['links'] variable.
I don't think my AJAX is actually doing anything sadly, so the code I'm using is below.
<script src="js/jquery-1.4.2.min.js" type="text/javascript">
function dequeue()
{
$.ajax({
type: "POST",
url: "common.php",
data: {action: "rem"},
success: function(output) {
alert(output);
}
});
}
</script>
and the PHP is
switch($_POST['action'])
{
case "rem":
array_pop($_SESSION['links']);
break;
default:
if(isset($_SESSION['current']) && $_SESSION['current'] != $_SERVER['REQUEST_URI'])
{
array_push($_SESSION['links'], $_SESSION['current']);
}
$_SESSION['current'] = $_SERVER['REQUEST_URI'];
break;
}
As far as I can tell, this will allow me to add a link to the history in the session variable unless I'm clicking on the "Back to Previous Page" link since that link will have the "rem" code. I'm also a bit suspicious of the $_SESSION['current'] = $_SERVER['REQUEST_URI']; and where it should be placed.
You can store array in a session and treat the array like a stack (use array_push and array_pop accordingly). When the user hits something but the back button, push the current page to the stack. otherwise, pop it.
I would do it like this if I had to:
$_SESSION["history"] = array();
And within the header of every "rememberable" page:
if(in_array($this_page, $_SESSION["history"])) {
unset($_SESSION["history"][array_search($this_page, $_SESSION["history"])]);
}
array_push($_SESSION["history"], $this_page);
What this does is: "If the page exists in the history, remove it from wherever it is and put it as the last page of the history. If not, just put it as the last page of the history". That way you won't have any loops.
