fetching one result from mysql

usually we use mysql queries to retrieve large  data contents.

But sometimes all we need is a number (Max, Count, or maybe just to retrieve unique feild). so we wont need to create an array.

to do so we can try the following code

$query=”select max(‘num’) from table”;

$result=mysql_query(query);

//now the magic line

$MaxNum=mysql_result($result,0,0)

there must be a reason for the 0, 0 but actually I dont know. if you know and can help me then I will be grateful.

When to use hight and when to use overflow

kinda tricky question but lets say
we had a code like

<style>
div#container
{
background-color:#FF0000;
}
div#someContent
{
float:left;

}
</style>
<div id="container">
<div id="someContent">My Name =D</div>
</div>

In the case above we dont know how long our text will be so adding a fixed height to the "container" div is a real problem, also not adding a height at all is even worst .

Why? Because simply not adding a height to the "container" div means it wont take the size of the floated divs inside, and so the red background wont show.

One intresting solve to this problem is using overflow:hidden on the container div.

actually there is three cases to this

Container div that has flexible height (auto height)

div#container
{
background-color:#FF0000;
overflow:hidden;
}

Container div which has fixed height and hide anything over its height

div#container
{
background-color:#FF0000;
overflow:hidden;
height:100px;
}

Finally Container div which has fixed height however divs inside can go over it

div#container
{
background-color:#FF0000;
overflow:visible;
height:100px;
}

Min-Height For IE

Yes, a nice and clean code

min-height:222px;
height:auto !important;
height:222px;

just since !important is there it will help to make it recognized for firefox but not IE6 and so the min hight will work

Joomla Page Title inside body

Wow, I searched for this for so long >.<
Tried
“Joomla Custom title”
“Joomla Page Title”
“Joomla Title in divs”
and so and so on o__o the good news its one line answer!!
ok here it is

<?php echo $mainframe->getPageTitle(); ?>

A href Padding Problem (IE and FireFox)

The problem is that when I have two a hrefs next to each other the padding is screwed in joomla. anyways here is what I did

Yes fixed padding on both IE and FireFox, here is the CSS Code

a.mainlevel:link, a.mainlevel:visited {

display:-moz-inline-box;
display:inline-block;
padding:10px;
}

the html code

<a class=”mainlevel” href=”link1.html”>Link1</a>

<a class=”mainlevel” href=”link2.html”>link2</a>

a good thing to know is that inline-block can have height and width =D

Hide Menu In Flash

Short and clean

var HideMenu:ContextMenu = new ContextMenu ();
HideMenu.hideBuiltInItems();
this.menu = HideMenu;

Limit variables on Flash with PHP

I was working with login script using the usual code I used to use for always

loadVariableNum(“test.php”,0,”POST”);

kinda nice but wait wait wait, what is this doing? loading all the root variables and spreading php variables on root randomly, HELL that is a real mess? it even didnt work in some cases (like my case today with my XML Flash file)
but yes as usual alot of search and alot of do. I got it to work perfectly with this very very clean code
Send and Load (To send specific variables to PHP) and Get Specific one back.
so here it is

on (release, keyPress ““) {
if (_root.user != “” && _root.pass != “”) {
_root.text=”Connecting..”;
//result_lv to get variables from php
var result_lv:LoadVars = new LoadVars();
//set_lv to post variables to php
var set_lv:LoadVars = new LoadVars();
set_lv.user = _level0.user;
set_lv.pass = _level0.pass;
set_lv.sendAndLoad(“newlogin.php”,result_lv,”POST”);
result_lv.onLoad = function(success:Boolean) {
if (success) {
if (result_lv.checklog == 1) {
_root.text=”Congrat you are logged”;
}
else
{
_root.text=”Sorry no such user name or password”;
}

} else {
_root.text=”Could Not Connect”;

}

};
}
}

I know this is flash thing but if you still curious about the php part then here it is

$user=$_POST['user'];
$pass=$_POST['pass'];
if ($user && $pass){
mysql_connect(“localhost”,”root”,”");
mysql_select_db(“database”);

$query = “SELECT * FROM users WHERE username = ‘$user’ AND password = md5(‘$pass’)”;
$result = mysql_query( $query ) ;

$num = mysql_num_rows( $result );
if ($num == 1){
print “status=You’re in&checklog=1″;
} else {
print “status=Sorry!&checklog=2″;
}
}
