It’s hopeful that, within next few month IT dept will explore there as an effort of making computerized the whole systems.Time will say the rest.

If we want to place checkboxes on the page that is already ticked or not without allowing them to be changed ,what are the ways?

• As a simple solution , use disabled keyword in checkbox html
• Another solution may be use of image of checkbox .

Let me discribe the some point of views of above solution. Whenever we use disabled keyword against any checkbox it lost her total beatiness and looked as died.M i right? U can see from picture.

And Replacing image is the more time consumer process and may have some more limitation.

• Besides them,Another solution is more tricky..Which I have been used in one of my reporting task before some days before where checkbox would be readonly,using little javascript
• Now let’s see it:
  

  function makeReadOnly(id)
  { var chkid=id ;

  if( document.getElementById(chkid).checked==false ) //no change for already ticked
  {document.getElementById(chkid).checked= true;}
  else
  {
  document.getElementById(chkid).checked=false ; //no change for alerady unticked
  }

  }

  Invoke this javascript function from html checkbox through onload event with element id as parameter,snipt is shown below
  
< input id="ch1" type="checkbox" onclick="makeReadOnly('ch1')" checked="checked" value="CH1" />
<input id="ch2" type="checkbox" onclick="makeReadOnly('ch2')" value="CH2" />


And done..show the inactive but live checkbox.

In joomla (version 1.0.x), whenever any Item displayed in details mode then the navigation of others item under same section/category shows in below format:

<< >>

If I would like to replace this simple navigation format with the title of others items under same section how it would be like?I think it would be more meaningful navigation.Any way, it’s turn to do the main things.

• Open the /component/com_content/content.html.php
• Find out the function named navigation() . line # 892
• Pest the following code inside the beginning of the function.


/*** Link list type navigaton
*@author : wasiur@gmail.com
*/
global $task, $mainframe, $database, $my;
/*Checking whether it is frontpage component or not and the task also
we don't want to it in frontapge*/
if(($_REQUEST["option"]!="com_frontpage") && ($_REQUEST["task"]=="view") ){
$opt=mosGetParam($_REQUEST,'option','');
if(eregi('content',$opt)){
$tsk=mosGetParam($_REQUEST,'task','');
$sid=mosGetParam($_REQUEST,'id','0');
if(eregi('category',$tsk)){
$row = new mosCategory( $database );
$row->load( $sid );
$sect=$row->section;
}elseif (eregi('view',$tsk)){
$row = new mosContent( $database );
$row->load( $sid );
$sect=$row->sectionid;
}else{
$sect=$sid; //$sect always contain the section id from url query string
}
}
$nullDate = $database->getNullDate(); //used for published check
$now = _CURRENT_SERVER_TIME; //ditto
//Select query checks whether item is published, is not checked out and whether user has permission to access item
$listque="SELECT id, title, created FROM #__content WHERE (sectionid IN (".$sect."))" //has specified id(s)
. " AND ( '$now' <= publish_down OR publish_down = '$nullDate' AND state = 1 )" //published
. " AND ( checked_out = 0 OR checked_out = $my->id )” //not checked out or checked out by me
. ” AND (access <= $my->gid)” //permission to access
. ” ORDER BY created desc”
. ” LIMIT 5″; //limit number of items to return
//query the DB
$database->setQuery( $listque );
$database->query();
//load items into object array
$content_list=$database->loadObjectList();
$total=count($content_list);
for ($i=0;$i<$total; $i++){ //showing with making link for each item $link="index.php?option=com_content&task=view&id=".$content_list[$i]->id.”&Itemid=”.$mainframe->getItemid($content_list[$i]->id); echo “

“; if($sid==$content_list[$i]->id) {
echo “
• “.$content_list[$i]->title . “

“;}
else
echo “

• “. ““. $content_list[$i]->title .”

” ;
echo “

“;
}
}


• save the file and Show the list navigation

Sample output :

Thanks

Recently I have done some task using div element. It seems to me very interseting and actually it’s the real flavour of DHTML. DIV has some interesting properties which are the main for it’s beautiness. At least as a new developoer..i think so. Now let me discribe in more details.
suppose, having a list of person which is generated from db and wanna see profiles of them individually. the points that..every person has several sources of profile. Now it’s need to give a scope to select the source which one the user want to see. I have used DIV to provide that option more interectivly. I have produced div for each person using the person’s id. Then this id is available through out the div . and Finally this div keep in hidden.
Whenever user will click on the person’s name link it will show the div with the link of several sources of profile. On the DIV, close link is also available to hide it again.
Next ,I have used it as a tab. Suppose there are some sectiones for any source of profile. Then I have loaded all section once in client PC but allows only one section to display.hmm, just act as tab..just hiding and showing the DIV. However..I had to face some sort of problem..i will focus later.
