How To Add a Count Value to a Foreach Statement?

Expand Post »
I have the following code section that is used for displaying a list of items and would like to modify it so it displays as a multi column display.

I have been told that I need to use a counter, but I cannot find any information on how to do this. - Can anybody here help me with this, please, or point to an existing article with the relevant information in it?

Re: How To Add a Count Value to a Foreach Statement?
I'd suggest a simple variable that increments with each iteration of the foreach loop. With something like the code below, you can access the number of the element with the counter variable.
PHP Syntax (Toggle Plain Text)
  1. // +--
  2. // | Loop through the products.
  3. // +--
  4.  
  5. $counter = 0; //Init the counter
  6.  
  7. foreach ($prodlist as $num => $prod) {
  8.       //Leave the below line at the top of the loop
  9.       $counter++; //Increment the counter with each product
  10.                   //The counter starts at 1 and counts up
  11.  
  12.       // +--
  13.       // | Print a table row opener.
  14.       // +--
  15.  
  16.       print '<tr class="' . $trclass . '">' . $eol . $eol;
  17.  
  18.       // +--
  19.       // | Print the tds and their content.
  20.       // +--
  21.  
  22.       $prodname  = $this->xhtml_encode($prod['name']);
  23.       $prodid    = $this->xhtml_encode($prod['id']);
  24.       $prodlink  = $this->link_namespace($app,'prodshow',$prod['id']);
  25.       $proddesc  = $this->xhtml_encode($prod['descshort']);

Re: How To Add a Count Value to a Foreach Statement?
Thank-you, FlashCreations, that looks to be exactly what I need and has already fixed a problem with multiple looping that I was having with a different attempted fix.

I have just tried to use the count value to split the display for the multi-column display, but this is not working at the moment...

PHP Syntax (Toggle Plain Text)
  1.       // +--
  2.       // | Print a table row opener.
  3.       // +--
  4.  
  5. 	if ($counter >= 1) {
  6.  
  7. 	print '<tr>';
  8.  
  9. 	}


...so I have now posted the entire code to (hopefully) make it easier for anyone else wanting to give me advice on modifying it:

I have also found another post: http://www.daniweb.com/forums/thread288497.html that references a similar problem, so I am studying that too for anything that might help with this.

Re: How To Add a Count Value to a Foreach Statement?
I have just modified the code and amended it with a control on the counter, so that nothing should be preventing it from displaying in a multi-column format, as shown below, but it is still refusing to do so ...in fact, the array items are now being displayed in a long line right across the screen, so the <tr> tags are clearly not being applied:

PHP Syntax (Toggle Plain Text)
  1. <?php
  2.  
  3. $app       = $this->globals('khxc_display.app');
  4. $ns        = $this->globals('khxc.namespace');

Re: How To Add a Count Value to a Foreach Statement?
This is the working code. - It has the counter with foreach statement and outputs the display in two columns:

PHP Syntax (Toggle Plain Text)
  1. <?php 
  2.  
  3. $app       = $this->globals('khxc_display.app');
  4. $ns        = $this->globals('khxc.namespace');
