Conditional statement for an array output

[dmh357]

Hello,

This is my first post an I am hoping someone can help me with and pretty easy request...

Here is my issue...

I am trying to create a data feed from a shopping cart. I need to create a CSV for the feed and I have everything complete but the nesting of the categories. I have the values in an array but need to have some additional deliminators added based on the length of the array.

Here are the details...

I am only going three layers deep and deliminating with a pipe '|', thus the array can return...

Level one|
Level one|Level two|
Level one|Level two|Level three|

What i need to maintain the structural in the resulting CSV is...

IF Level one only then add '|' . '|'; (two pipes) -- top level
IF Level one|Level two| then add '|'; (one pipe) -- 2nd level
Level one|Level two|Level three then no pipe required -- 3rd level

Example output of array....

top|
top|product|
top|product|model|

Desired output...

top|||
top|product||
top|product|model|

NOTE: Pipes "|"

Thanks

If you have an array of what goes in each line (e.g., ("top", "product")), then use [man]array_pad[/man] to stick an appropriate number of empty strings on the end. Then print the whole padded array with "|"s in between.

Hi,

Thanks, Still having an issue as the array is calculated kind of silly.

Here is my output...

$output .= array_pad($cat_info[$products['categories_id']]['link'], 3, "|");

This is the code to create the array

$cat_info = array();
  for ($i=0; $i<sizeof($inc_cat); $i++)
    $cat_info[$inc_cat[$i]['id']] = array (
    'parent'=> $inc_cat[$i]['parent'],
    'name'  => $inc_cat[$i]['name'],
    'path'  => $inc_cat[$i]['id'],
    'link'  => '' );

   for ($i=0; $i<sizeof($inc_cat); $i++) {
  $cat_id = $inc_cat[$i]['id'];
  while ($cat_info[$cat_id]['parent'] != 0){
    $cat_info[$inc_cat[$i]['id']]['path'] = $cat_info[$cat_id]['parent'] . '_' . $cat_info[$inc_cat[$i]['id']]['path'];
    $cat_id = $cat_info[$cat_id]['parent'];
    }
  $link_array = split('_', $cat_info[$inc_cat[$i]['id']] ['path']);
  for ($j=0; $j<sizeof($link_array); $j++) {
    $cat_info[$inc_cat[$i]['id']]['link'] .= $cat_info[$link_array[$j]]['name'] . '|';
    }
  }

Any help would be much appreciated!

No, you don't want to pad it with pipes, you want to pad it with empty strings; the pipes will go in when you join the array elements together.

$line = array('top', 'product');
$output_line = join('|', array_pad($line, 3, '')) . '|'; // one more pipe to go on the end.
echo $output_line;
