Can you explain this assignment? What does it mean?
boolean activityExists = testIntent.resolveActivity(pm) != null;
It means to assign true if testIntent.resolveActivity(pm) does not return null otherwise assigns false.
Understandable long form of this would be
boolean activityExists;
if(testIntent.resolveActivity(pm) != null) {
activityExists = true;
} else {
activityExists = false;
}
I am getting problems on using multiple images in the background of my web pages. I used the following codes for it:
body{
background-image: url(images/img1.png), url(images/img2.png); }
The code I used gives me two images on background but I want to keep one of the image exactly on the center. How can it do so using CSS?
I’m trying to put a ZF website on the Internet which works well on my local machine (WAMP).
But on the Linux server, only the main page can be properly displayed. For the other pages, I’ve got a fatal error:
Fatal error: Uncaught exception

I activated the URL rewriting. I’m using modules. The index.php and application.ini are very basic, we didn’t custumize it.
I suppose that there is something wrong with the configuration… Thanks.
When deploying application from windows platform to Linux, most typical type of error that can be encountered is due to the filename cases. Linux system are very strict about file name and cases.
The error you are encountering is also probably one of these cases. Check the name of ErrorContainer.php and try to match the name you specify in your route and file system.
For some reason I can’t get an image to span 100% width across the browser.
You can find my site here.
My div reads:
<div class="home" style="background-image: url(http://payload51.cargocollective.com/1/7/237315/3336908/HomeImage_o.jpg);
background-attachment: fixed; height: 560px; width: 100%; opacity: 1; background-position-y: 0px; background-position-x: center; background-repeat: no-repeat no-repeat; ">
</div>
Any help would be appreciated.
I don’t like the idea of stretching a image to fit the browser’s window. As this depends on the client’s machine on how the site will appear.
So, I will not suggest searching for such solutions. Rather:
What I am trying to do is parse this JSON: http://www.theunjust.com/test/container.php
And just get it to show at this point…
Here is my current code(its all jacked up)
$(document).ready(function(){
var jsonurl = "container.php";
$.getJSON(jsonurl, function(data) {
$.each(data.encompass,function(i,valu){
var content,
cont = '',
tainers = valu.containers;
$.each(tainers, function (i) {
var tid = tainers[i].TID,
top = tainers[i].Top,
cat = tainers[i].Category,
date = tainers[i].Date,
icon = tainers[i].Icon,
clink = tainers[i].ContainerLink,
uid = tainers[i].UniqueID;
cont += '<a href="' + clink + '">' + uid + '</a> ';
$('ul').append('<li>' + tid + ' - ' + top + ' - ' + cat + ' - ' + date + ' - ' + icon + ' - ' + clink + ' - ' + uid + ' (' + cont + ')</li>');
});
});
});
});
I know that the code doesn’t make sense, this is more of a learning experience for me rather than a functioning tool. The issue may be in the JSON data itself, if that is the case, what stackoverflow web service post would you recommend?
What I eventually aim to do is run multiple web services and combine them… So that container.php loads and has all of the information that is required for a wrapping div, then entries.php loads and fills the divs that was generated by containers..
I’m currently learning jQuery and Honestly, I’m not to this level yet, but I am getting there pretty quick.
I really appreciate the help, and would like if you could point me in the direction to become a JSON parsing pro!
containers contain single node. So simply use
$.each(tainers, function (i, v) {
var tid = v.TID,
top = v.Top,
cat = v.Category,
date = v.Date,
icon = v.Icon,
clink = v.ContainerLink,
uid = v.UniqueID;
cont += '<a href="' + clink + '">' + uid + '</a> ';
$('ul').append('<li>' + tid + ' - ' + top + ' - ' + cat + ' - ' + date + ' - ' + icon + ' - ' + clink + ' - ' + uid + ' (' + cont + ')</li>');
});
Is there a way to fix a position on the x-axis only? So when a user scrolls up, the div tag will scroll up with it, but not side to side?
Its a simple technique using the script also. You can check a demo here too.
JQuery
$(window).scroll(function(){
$('#header').css({
'left': $(this).scrollLeft() + 15
//Why this 15, because in the CSS, we have set left 15, so as we scroll, we would want this to remain at 15px left
});
});
CSS
#header {
top: 15px;
left: 15px;
position: absolute;
}
Update Credit: @PierredeLESPINAY
As commented, to make the script support the changes in the css without having to recode them in the script. You can use the following.
var leftOffset = parseInt($("#header").css('left')); //Grab the left position left first
$(window).scroll(function(){
$('#header').css({
'left': $(this).scrollLeft() + leftOffset //Use it later
});
});
Demo 🙂
I have a file that resides in:
/Library/WebServer/Documents/wordpress/wp-content/themes/directorypress/sidebar-left-big.php
I have another file in sub directory:
/Library/WebServer/Documents/wordpress/wp-content/themes/directorypress/template_directorypress/_gallerypage.php
And in _gallerypage.php I have php include:
<?php include('../sidebar-left-big.php'); //left sidebar, category navigation and ads ?>
Error I get:
Warning: include(../sidebar-left-big.php) [function.include]: failed to open stream: No such file or directory in /Library/WebServer/Documents/wordpress/wp-content/themes/directorypress/template_directorypress/_gallerypage.php on line 9
Warning: include() [function.include]: Failed opening '../sidebar-left-big.php' for inclusion (include_path='.:') in /Library/WebServer/Documents/wordpress/wp-content/themes/directorypress/template_directorypress/_gallerypage.php on line 9
It seems to me I’m doing everything correctly.
I thought that maybe problem is that _gallerypage.php is loaded via include in another file, so ../ relative to that leads to error. But error doesn’t say anything as to where it thinks path to sidebar-left-big.php is.
use include dirname(__FILE__).'/../sidebar-left-big.php';
Yes, You are right.
When you include the _gallerypage.php from another file, it does take the path relative to itself. So, you should fix this.
The best way, might be avoid such difficulties. There are number of ways to do this. Like, One would be define a global root in a constant and include every thing, everywhere as per it.
For example:
define("BASE" , "/wordpress"); //Define a base directory
//now whenever you are including and requirng files, include them on the basis of BASE
require(BASE."/admin/.../some.php");
Could any one help me on how to navigate from first tab to second tab by clicking a hyperlink in first tab using JQUERY UI tabs?
You can refer the jQuery UI Tabs documentation for your problem, its very well mentioned
var $tabs = $('#example').tabs(); // first tab selected
$('#my-text-link').click(function() { // bind click event to link
$tabs.tabs('select', 2); // switch to third tab
return false;
});
You can switch between tabs freely by following the indexes using select method.
An example:
$("#tabs").tabs('select', 1);
Attach this snippet to the click handler of the link on the content of first tabs.
Example:
For a link like this:
<a href="some.html" id="nextTab">Go to Next Tab</a>
jQuery:
$("#nextTab").click(function() {
$("#tabs").tabs('select', 1);
});
We have our authentication delegated to another domain (Window Identify framework, federated authentication setup). Now, if the the session timed out before an ajax request , server redirects the request to authentication server. Since it becomes a cross domain call, ajax request is cancelled by the browser. Is there a way i can detect this in jquery/javascript ?
I inspected the status property of the xhr object which set to 0 in such case, but is it a good indicator for cancelled requests? (I am using jquery $.ajax to make ajax requests)
Actually, there isn’t any definite way to detect this, unless you define it manually.
For example: Store you domain name in a var
var domain = "http://www.domain.com";
Next, whenever you have a URL you need to check, if it belongs to same domain, you can check like this:
var url = "http://www.domain.com/page.html";
if(url.indexOf(domain) >0) {
//Yes it belongs to same domain
}
Note: This is rather a very simple example to give you an idea
I am trying to get the ID from the end of this string the 4305 after the -. The code below works from left to right and shows 150. How can i make it work from right to left to show the 4305 after the -?
$mystring = "150-Adelaide-Street-Brisbane-Cbd-4305";
$mystring = substr($mystring, 0, strpos($mystring, "-"));
echo $mystring;
Updated: This does what i need but i’m sure there is a better way to write it:
$mystring = "150-Adelaide-Street-Brisbane-Cbd-4305";
$mystring = substr(strrev($mystring), 0, strpos(strrev($mystring), "-"));
echo strrev($mystring);
You can use strrpos to get the last hyphen in the string, and then take the rest of the string after this character.
$mystring = "150-Adelaide-Street-Brisbane-Cbd-4305";
$mystring = substr($mystring, strrpos($mystring, "-") + 1);
echo $mystring;
Most easiest way is definitely using explode.
By using explode, you can split the string into an array with each parts accessible as individual identifiers using the indexes.
Usage Example:
$mystring = "150-Adelaide-Street-Brisbane-Cbd-4305";
$mystring = explode("-", $mystring);
echo $mystring[count($mystring)-1]; //Extract the last item
