Array help

[n000bie]

Hi,

 

Code

<?php 
$a = '20,44,72,73';

$b = explode(',', $a);

$total = count($b);

$c = 20;

$d = in_array($c, $b);

if ($d) 
{
	if ($total==1) { echo 'There is only 1 record and will be redirected to (its) detail page.';}
	else { echo "There are more than 1 record";}
}

?>

 

What I am trying to do is,

if there is only 1 value in $a, do something

if there is more than 1 value in $a do something else

 

$a comes from a table field (this is the category id and is saved seperated with comma)

 

This code works if the value of $a = 20 (or any other single number)

 

It does not work if $a has more values seperated with comma.

 

Can anyone help me please.

Are you saying the value of $a will be coming from a table?

 

You might want to consider using array('value','value','value')

 

And you can test the array with empty() ..

 

And if you are pulling all of the data from a table, you will probably want to use foreach()

Yes I have done that

 

this is my actual code

 

if(isset($_REQUEST['brand']))
	{	
		$sSqlQuery = 'where published=?';

		$row = $tobj->find_all($sSqlQuery,array('Y'));

		if($tobj->_row_count>0)
		{

			foreach($row as $r)
			{
				$brand = explode(',',$r->brand_id);

				$myTotalBrand=count($brand);

				if(in_array($cat_id,$brand))		
				{
					//echo $myTotalBrand;  
					if ($myTotalBrand==1) 
					{
						echo "<div style='text-align:center; height:100px; margin-top:50px;'><img src='".SITE_URL."/images/loading10.gif' /><div>loading...</div></div>";
			echo "<script>document.location.href='".SITE_URL."/shop/".$r->slug."'</script>"; 
					}
					else 
					{
					  $count_check++;
					  if(($count_check%6)==0)
					  {
						  echo '<li style="margin-right:0px;">';
					  }
					  else
						  echo '<li>';
					  
					  echo "<a href='".SITE_URL."/shop/".$r->slug."'>";echo "<img src=\"$r->logo_img\">"; echo "</a>";
					  echo "<a href='".SITE_URL."/shop/".$r->slug."' class='fixht'>"; echo ucfirst($r->shop_title); echo "</a>";
					  echo '</li>';
					}
				} // end in array check
			}

		} // end row count

	}
