<ul> within another <ul> inherits style

Question by JamWaffles

I have the following structure in some HTML:

<ul class="li_inline">
        <ul class="li_block">
            <li>Stuff under stuff</li>
        <ul class="li_block">
            <li>Stuff under stuff</li>

With the CSS like this:

.li_inline li
    display: inline;

.li_block li
    display: block;

What I would like to happen is to have the two inner <ul>s side by side, but any <li>s inside them to be below each other. This is so I can get a sidebar and main body side by side, but elements inside them behave normally (ie. one below the other).

Can someone suggest some CSS I can use so that the inner (li_block) lists’ <li> elements are displayed as block elements, but the <ul>s themselves are displayed side by side?



Answer by Starx

Use a reset rule.

ul ul { list-style:none; padding: 5px 20px; margin: 5px 10px; }

In your case using the !important can get your job done. But try not to use it

PHP get all function arguments as $key => $value array?

Question by web lover

function register_template(){
    # the result was an array ( [0] => my template [1] => screenshot.png [2] => nice template .. ) 


register_template(     # unkown number of arguments
    $name = "my template",
    $screenshot = "screenshot.png",
    $description = "nice template .. "

BUT , I want the result array as $key => $value form , $key represents the parameter name.

Answer by Starx

It’s easy. Just pass the array as the parameter instead then later access it as $key => $value inside the function.


This was the best I could think of

$vars = array("var1","var2"); //define the variable one extra time here
$$vars[0] = 'value1'; // or use $var1
$$vars[1] = 'value2'; // or use $var2

function myfunction() {
    global $vars;
    $fVars = func_get_args();
    foreach($fVars as $key=>$value) {
       $fvars[$vars[$key]] = $value;
    //now you have what you want var1=> value1


I haven’t tested it…BTW. But you should get the point

Center div horizontally

Question by Don

On this page, I would like to horizontally center the main #container div relative to the page. Normally I would achieve this by adding a CSS rule,

#container { margin: 0 auto }

However, the layout of this page (which I did not write), uses absolute positioning for #container and most of its child elements, so this property has no effect.

Is there any way I can achieve this horizontal centering without rewriting the layout to use static positioning? I’ve no problem with using JavaScript/JQuery if that’s the only way to achieving my objective.

Answer by Starx

Same as @rquinn answer but this will adjust to any width. Check this demo

Count especific table rows in mysql

Question by NORM

I want to count how many rows I have in a mysql table and display it in html.

For example:

There is: Item 1, Item 2, Item 3, Item 4, Item 5, Item 6

If Item 1 and Item 2 are filled, I want a html code to say – 2 items in row

any ideas?

Answer by Starx

IF its total rows you are after, then as Nishant mentioned above you could do something like this

$query = "SELECT COUNT(*) FROM mytable WHERE myfield='myvalue'"; 

I am counting all the ids, because it will reduce the time taken to calculate the total instead of ‘*’ and

Thanks to Nico, count(*) and count(column) are not so different considering performance. Here is a comparision

Use a where condition to narrow your total as you require.

How to add duplicate image on same page with java Script after page loaded

Question by Shoun

i m facing a problem, what i ma doing is that. i have a server side image button. what i wana do is that after that page loads at client side, i want to place that same image with same navigation url at another location on same page. Can any body tell me how to do that? same as i also want to hide some text on page with javascript. any idea??

Answer by Starx

use .clone() method.

An Example:

Let ‘s suppose your img being this

<img class="yourimageclass" src="Your/path/to/image.jpg" ?>
<!-- And this being where you want to copy it -->
<div class="whereuwanttocopy"></div>

Then your jQuery would be


To hide some text in your page, wrap them into some container, so that we could address that piece of content

<span class="todhide">here is the text to hide</span> and here is the text to not hide

Then use simple $(".tohide").hide() whenever you want to hide the text

Is it possible to Copy images from web to your Hard Drive?

Question by Starx

I am trying to create a page for just personal use. What I want to do is, create a system through which I can download images to my local hard disk, directly by providing the link through a localhost like WAMP. The reason I am trying to do is, I want the images to be automatically sorted onto my hard disk. My form field will be something like this

<form method="POST" action="process.php">
   <input type="text" name="URL" id="URL" />
   <input type="text" name="category" id="category" />
   <input type="text" name="subcategory" id="category" />
   <input type="submit">

Now, in the process.php

//This is just a sample... So please ignore the roughness of the coding


// If you noticed, the categories and subcategories are actually the name of directory, where I want the picture to go be saved....

I am thinking my approach is wrong. How can I achieve something like this?


Warning: copy(images/image.jpg) [function.copy]: failed to open stream: No such file or directory in

Answer by Starx

Ok, I used curl instead to achieve what i am expecting. Here is the piece of code

$img = $_POST['url'];
$fullpath = $_POST['category']."/".$_POST['subcategory']."/".basename($img);
$ch = curl_init ($img);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
curl_close ($ch);                   
$fp = fopen($fullpath,'x');
fwrite($fp, $rawdata);

jQuery – .css("right", posVar); does not work

Question by Tomkay

The Main objective here is to make an instand “jump” to the right. Like I said – I dont want to use .animate, because it makes a little “flashing” effect – because it is not instant. I think .css will make an instant “jump” to the right, without flashing effect.

You can find the full javascript code for my gallery here (german comments):

And the HTML

I dont know why this will not work.. Instead of using .css I actually have to workaround this issue with .animate $("#gallery ul").animate({right: posVar},0);

I dont get it.. here is my actual (Javascript, JQuery) code:

   var posVar = 2838;        
   $('#gallery ul').css("right", posVar);

Whats wrong with that?

#gallery ul css

#gallery ul {
width:14000px; /*auto calculated from javascript */

Answer by Starx

Css attributes:left, right, top, down will not work with display:block try display:absolute or display:fixed

I dont know what was on my mind when I wrote that answer. I mean to say…. you need position:absolute or position:fixed or position:relative

And I think the problem with your code is there is not “px” at the end…

I have fiddeled it, and here it is http://jsfiddle.net/Starx/8w6cS/



AND IF YOU TRYING TO MOVE YOUR ul to 2838px to the right Here is your solution
