Remove shopping cart items from table?

aromakat

I currently have a web service displaying a list of recepes that the user has added to their account.

 $ch = curl_init();
		  $url = "http://myservice.url/app/s?session=".$_GET['session'];
		  curl_setopt($ch, CURLOPT_URL, $url);
		  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
		  $output = curl_exec($ch);
		  curl_close($ch);
		  $arr = split(',', $output);
		  foreach ($arr as &$url) {
			echo $url;
			echo '<hr>';
		}
		//echo $output;

This works as it should, but on the page where this list is displayed, is a table at the bottom that should list all of the other available recipes that the user has not selected, not including those that have been. The html table, completely static, below:

 <table width="100%" border="0">
  <tr align="center">
    <td><a href="pdf/NAVARIN_PRINTANIER_REV.pdf">Navarin Printanier</a></td>
    <td><a href="pdf/POULET_ROTI_A_LA_NORMANDE_REV.pdf">Poulet R&oacute;ti &aacute; la Normande</a></td>
    <td><a href="pdf/Boeuf_Bourguignon_REV.pdf">Boeuf &aacute; la Bourguignonne</a></td>
    <td><a href="pdf/Bavarois_au_Chocolat_REV.pdf">Bavarois au Chocolat</a></td>
  </tr>
  <tr align="center">
    <td><a href="pdf/Bavarois_aux_Fruits_REV.pdf">Bavarois aux Fruts</a></td>
    <td><a href="pdf/ARTICHAUTS_AU_NATUREL_REV.pdf">Artichauts au Naturel</a></td>
    <td><a href="pdf/Reine_De_Saba_REV.pdf">Reine de Saba</a></td>
    <td><a href="pdf/SUPREMES_DE_VOLAILLE_AUX_CHAMPIGNONS_REV.pdf">Supr&eacute;mes de Volaille aux Champignons</a></td>
  </tr>
  <tr align="center">
    <td><a href="pdf/FOIES_DE_VOLAILLE_EN_ASPIC_REV.pdf">Foies de Volaille en Aspic</a></td>
    <td><a href="pdf/Pate_de_Canard_En_Croute_REV.pdf">P&aacute;t&eacute; de Canard En Cro&uacute;te</a></td>
    <td><a href="pdf/Beurre_Blanc_REV.pdf">Beurre Blanc</a></td>
    <td><a href="pdf/CREPES_DE_POMMES_DE_TERRE_REV.pdf">Cr&eacute;pes de Pommes de Terre</a></td>
  </tr>
  <tr align="center">
    <td><a href="pdf/MayonnaiseREV.pdf">Mayonnaise</a></td>
    <td><a href="pdf/Sauce_Hollandaise_REV.pdf">Sauce Hollandaise</a></td>
    <td><a href="pdf/HOMARD_THERMIDOR_REV.pdf">Homard Thermidor</a></td>
    <td><a href="pdf/Poached_EggsREV.pdf">Oeufs Poch&eacute;s</a></td>
  </tr>
</table>

Can someone help explain what I need to do to not include the recipes that have been added to the "shopping cart"?

well, ideally you'll store something in a database - but I'll do it for now in a static example. If you were doing it in a dynamic way it would be something like this (and I'm doing this so you'll work with it and learn in the process):

?><table><?php

$recipes=array(
   1=>array(
      'Name'=>'Macaroni and Cheese',
      'Description'=>'My favorite',
      'Cost'=>14.95
   ),
  /* use your imagination */
   2=>array(
     'Name'=>'Spaghetti',
     'Desccription'=>'Great after a 5k',
    'Cost'=>'Free at a good race'
   ),
   /*etc.*/

);
foreach($recipes as $n=>$v){
   if(in_array($n, $shoppingCartArray)) continue; //don't show the row
   ?><tr>
   <td><?php echo $v['Name']?></td>
   <td><?php echo $v['Description']?></td>
   <td><?php echo $v['Cost']?></td>

   </tr><?php

}

?></table><?php

Hope that helps once you learn to use a database - $recipes would be gotten by a query. see below for the static way

Thank you so much sfullman!

The code you provided makes complete sense and I will start hacking away at it.

And thanks for providing the DB solution as well, because I am indeed trying to learn PHP by diving in head first....not just looking for a free answer to a current issue.

The DB isn't an option this time around - but I will still be studying and taking into account your example.

Thanks again! I will post in a bit if I run into any issues... Or, to say it works.
