Checkbox in PHP

[abhijitp]

Hi,

I am a newbie and have very little knowledge of PHP. I want to create dependencies on links using a checkbox (or any easier tool).

 

Eg:

Link 1

Link 2

Link 3

 

If the checkbox on link 2 is clicked, then the link 2 should not be active unless Link 1 in opened. Where as Link 3 should be accessible.

 

I have written below code:

 

/* Loop for No. of items/links */

$counter = 0;

foreach ($item as $item_id => $details)
{
    if($details['visible'] == 0)
    {
    		continue;		
    }
	$counter++;


/*Checkbox created */

$typec = "Checkbox";
$namec = "formDoor[]";
$valuec = "";
$checking = "<form method=".'POST'.">".
		"<input type="."'".$typec."'"."name="."'".$namec."'"."value=".$valuec." />".
		"</form>";


/*Dependency condition */


$dsp_ord = '';

$aDoor = $_POST['formDoor'];

$result = "";

if(is_null($aDoor)) 
		{
		 $result =	  	'<td align="left" valign="top">'.'<a href="#" onClick="javascript:window.open('."'".$url."'".	",'mywindow1','width=1000, height=600'".');">'.$url_name . '</a>' . "</td>\n";
		}
    	
		else
		{
		$result =	  	'<td align="left" valign="top">'.'<a href="#">'.$url_name . '</a>' . "</td>\n";
		}

 

With above code the checkbox only appears but doesnt do anything when the page is reloaded, the checkbox is also reloaded. It doesnt get saved.

you need to get the checkboxes status either with $_GET or $_POST
