    search from website not google search

    in HTML Help

    Posted

    hello everyone....

     

    what i am trying is.. i have created a simple 5 pages HTML website... and i need to add a search in it.... Is it possible without php ??

     

    what i found is a code for google search,, which searches through web (obviously) and  not in my site.... any help ??

    static keyword and scope resolution problem

    in PHP Coding Help

    Posted

    i am learning static keyword.. and find this example , but it shows error ,, which i highlited below

     

    <?php
    class a{

    static protected $test="class a";

    public function static_test(){

    echo static::$test; // Results class b             here the program shows error .... can we use static keyword to call the variable or we have to use a class name?
    echo self::$test; // Results class a

    }

    }

    class b extends a{

    static protected $test="class b";

    }

    $obj = new b();
    $obj->static_test();
    ?>

     

    getting confused about these two terms.. i tell you what i understand till now about them... make me clear plz

     

    Scope resolution (::) - this is used to call constants and static variables, static functions and classes but not with instance/object ?? am i right ?? anything more about it ?

     

    static keyword -   we can call static variable and functions without  the need of instantiation i.e directly  using scope resolution.... the class also becomes static , if any property  or method declared static in it. After inheriting from such class  if we override property  or method we have to use static keyword again while override,,,, ok or i need to learn more ??

    Posted

    hello friends... i have uploaded the videos,, now i want to see it...

     

    i uses the <iframe> tag ,but it shows video only in firefox and also starts on page load... which i dont want,,,,,

     

    For chrome HTML5 video tag is being used... and i dont know about IE... so how should i write my code???

     

    here is my code :-

     

    <?php
        while($f=mysql_fetch_array($q))
        {
            if($f['video'] != ' ')
            {
        ?>
       <li> <video controls="controls" width="450" height="280">
        <source src='upload/<?php echo $f["event"]; ?>/video/<?php echo $f["video"];?>' type="video/mp4" height="200" width="200">
        </video></li><br />

     

    <iframe src="upload/<?php echo $f["event"]; ?>/video/<?php echo $f["video"];?>" height="200" width="200"></iframe>
      
      <?php
            }
        }
    ?>

     

    How could i put condtions for browsers the chrome uses video tag and not iframe tag.., as now it shows two videos ,, but working other blank(obviously for iframe tag)... and vice-versa for firefox... and what to do for IE

     

     

     

    problem with dereference marker/pointer

    in PHP Coding Help

    Posted

    can anyone clear me what is the difference between  ->    and   => ??

     

    when we call method of a class, we use

     

    $obj -> method();

     

    can we use this also ???

     

    $obj => method();

     

    and also ,when we assign a value to a variable ( e.g $name ) , we us

     

    $obj->name="Smith";

     

    but what this means ??  $obj->$name ..    or is it incorrect  ??  or am i  assigning value of $name to $obj ??

     

    i have seen a working code ... what it means

     

    $obj= new name;  //name is a class
    foreach($obj as $var=>$value)
