Ok. Well i'm designing a wishlist generator and its giving me a weird result when it generates the final list. Here our the codes for the entree interface and the your list script.

<?#########################Create Entree Interface##########################write out top of entree table$form_block = "<form method=\"post\" action=\"your_wishlist.php\"><input type=\"hidden\" value=\"$_POST[wish_list_name]\"><table cellspacing=5 cellpadding=5><tr><th>Item Name</th><th>Item Price</th><th>Item Location</th><th>Rating</th></tr>";#count from 0 until you reach specified number of entree itemsfor($i = 0; $i <$_POST[item_num]; $i++){#add one entree row$form_block .= "<tr><td align=\"center\"><input type=\"text\" name=\"item_name[$i]\" size=\"25\"></td><td align=\"center\"><input type=\"text\" name=\"item_price[$i]\" size=\"15\"></td><td align=\"center\"><input type=\"text\" name=\"item_location[$i]\" size=\"25\"></td><td align=\"center\">	<select name=\"item_rating[$i]\"><option value=\"1\">1</option><option value=\"2\">2</option><option value=\"3\">3</option><option value=\"4\">4</option><option value=\"5\">5</option><option value=\"6\">6</option><option value=\"7\">7</option><option value=\"8\">8</option><option value=\"9\">9</option><option value=\"9\">9</option><option value=\"10\">10</option>	</select></td></tr>";}##now write in the end of the form block#$form_block .= "<TR><TD ALIGN=CENTER COLSPAN=4><INPUT TYPE=\"submit\" VALUE=\"Create Wishlist\"></TD></TR></TABLE></form>";#now write it out to the page?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html><head><title>Wish List Generator</title><link rel=stylesheet type="text/css" href="style.css"></head><body><H1><p>Add Items To <? echo "$_POST[wish_list_name]"; ?></p></H1><? echo "$form_block"; ?></BODY></HTML>

<?#########################Create WishList Print-Out##########################Build begginging of table$wish_list = "<table cellspacing=5 cellpadding=5><tr><th>Item Name</th><th>Item Price</th><th>Item Location</th><th>Rating</th></tr>";for ($i = 0; $i < count($_POST[item_name]); $i++) {#add the data to the wishlist one row at a time$wish_list .= "<tr><td align=\"center\">$_POST[item_name][$i]</td><td align=\"center\">$_POST[item_price][$i]</td><td align=\"center\">$_POST[item_location][$i]</td><td align=\"center\">$_POST[rating][$i]</td></tr>";}##write this out to the screen?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html><head><title>Wish List Generator</title><link rel=stylesheet type="text/css" href="style.css"></head><body><H1><p><center><? echo "$_POST[wish_list_name]"; ?></p></H1><? echo "$wish_list"; ?></BODY></HTML>

Try this function to print out the $_POST array:

// array_debug - print out a formatted list of an arrayfunction array_debug($array_name) { 		  echo '<pre>'; 		  ksort($array_name); 		  print_r($array_name); 		  echo '</pre>'; 		} // end func

Call the function using the array name used in your script.

I tried what you said...

// array_debug - print out a formatted list of an arrayfunction array_debug($array_name) { echo '<pre>'; ksort($array_name); print_r($array_name); echo '</pre>'; } // end func
and now instead of getting a Array[0] and so on, i get that chunk of code in each place that should be the information. Anything else i can try?

Yes i did. Here is how your_list.php looks now after i inserted your code block. But one thing. I After your code block didn't work, i tried taking the <pre> stuff out. So this script is puposfully missing that. I don't know if that's wrong or right.your_list.php

<?#########################Create WishList Print-Out##########################Build begginging of table$wish_list = "<table cellspacing=5 cellpadding=5><tr><th>Item Name</th><th>Item Price</th><th>Item Location</th><th>Rating</th></tr>";for ($i = 0; $i < count($_POST[item_name]); $i++) {#add the data to the wishlist one row at a time$wish_list .= "<tr><td>// array_debug - print out a formatted list of an arrayfunction array_debug($_POST[$item_name]) { 		  ksort($_POST[item_name]); 		  print_r($_POST[item_name]); 		} // end func</td><td>// array_debug - print out a formatted list of an arrayfunction array_debug($_POST[item_price]) { 		  ksort($_POST[item_price]); 		  print_r($_POST[item_price]); </td><td>// array_debug - print out a formatted list of an arrayfunction array_debug($_POST[item_location]) { 		  ksort($_POST[item_location]); 		  print_r($_POST[item_location]); </td><td>// array_debug - print out a formatted list of an arrayfunction array_debug($_POST[item_rating]) { 		  ksort($_POST[item_rating]); 		  print_r($_POST[item_rating]); 		} // end func</td></tr>";}##write this out to the screen?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html><head><title>Wish List Generator</title><link rel=stylesheet type="text/css" href="style.css"></head><body><H1><p><center><? echo "$_POST[wish_list_name]"; ?></p></H1><? echo "$wish_list"; ?></BODY></HTML>

And if this is helpful...entree_interface.php (Note: this script currently works to my knowlage)

<?#########################Create Entree Interface##########################write out top of entree table$form_block = "<form method=\"post\" action=\"your_wishlist.php\"><input type=\"hidden\" value=\"$_POST[wish_list_name]\"><table cellspacing=5 cellpadding=5><tr><th>Item Name</th><th>Item Price</th><th>Item Location</th><th>Rating</th></tr>";#count from 0 until you reach specified number of entree itemsfor($i = 0; $i <$_POST[item_num]; $i++){#add one entree row$form_block .= "<tr><td align=\"center\"><input type=\"text\" name=\"item_name[]\" size=\"25\"></td><td align=\"center\"><input type=\"text\" name=\"item_price[]\" size=\"15\"></td><td align=\"center\"><input type=\"text\" name=\"item_location[]\" size=\"25\"></td><td align=\"center\">	<select name=\"item_rating[]\"><option value=\"1\">1</option><option value=\"2\">2</option><option value=\"3\">3</option><option value=\"4\">4</option><option value=\"5\">5</option><option value=\"6\">6</option><option value=\"7\">7</option><option value=\"8\">8</option><option value=\"9\">9</option><option value=\"9\">9</option><option value=\"10\">10</option>	</select></td></tr>";}##now write in the end of the form block#$form_block .= "<TR><TD ALIGN=CENTER COLSPAN=4><INPUT TYPE=\"submit\" VALUE=\"Create Wishlist\"></TD></TR></TABLE></form>";#now write it out to the page?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html><head><title>Wish List Generator</title><link rel=stylesheet type="text/css" href="style.css"></head><body><H1><p>Add Items To <? echo "$_POST[wish_list_name]"; ?></p></H1><? echo "$form_block"; ?></BODY></HTML>

Did i put it in the right place? What do i need to do differently to make this work?

What you've not realized is that the code given to you defines a function, you need only to call it.Instead of:

<?phpfunction array_debug($_POST[$item_name]) { 		  ksort($_POST[item_name]); 		  print_r($_POST[item_name]); 		}function array_debug($_POST[item_price]) { 		  ksort($_POST[item_price]); 		  print_r($_POST[item_price]);  }?>

Use:

<?phpfunction array_debug($array_name) { 		  echo '<pre>'; 		  ksort($array_name); 		  print_r($array_name); 		  echo '</pre>'; 		} //This defines the function.array_debug($_POST[item_name]); // This calls the function.?>

ok. I did what you said and got this. The following is the source code for the page it generated so you can see what is happening:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html><head><title>Wish List Generator</title><link rel=stylesheet type="text/css" href="style.css"></head><body><H1><p><center></p></H1><table cellspacing=5 cellpadding=5><tr><th>Item Name</th><th>Item Price</th><th>Item Location</th><th>Rating</th></tr><tr><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td></tr><tr><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td></tr><tr><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td><td>function array_debug() { 		  echo '<pre>'; 		  ksort(); 		  print_r(); 		  echo '</pre>'; 		} //This defines the function.array_debug(Array); // This calls the function.</td></tr></BODY></HTML>

Now here is my source code for your_list.php after i inserted the recomended block.

<?#########################Create WishList Print-Out##########################Build begginging of table$wish_list = "<table cellspacing=5 cellpadding=5><tr><th>Item Name</th><th>Item Price</th><th>Item Location</th><th>Rating</th></tr>";for ($i = 0; $i < count($_POST[item_name]); $i++) {#add the data to the wishlist one row at a time$wish_list .= "<tr><td>function array_debug($array_name) { 		  echo '<pre>'; 		  ksort($array_name); 		  print_r($array_name); 		  echo '</pre>'; 		} //This defines the function.array_debug($_POST[item_name]); // This calls the function.</td><td>function array_debug($array_name) { 		  echo '<pre>'; 		  ksort($array_name); 		  print_r($array_name); 		  echo '</pre>'; 		} //This defines the function.array_debug($_POST[item_price]); // This calls the function.</td><td>function array_debug($array_name) { 		  echo '<pre>'; 		  ksort($array_name); 		  print_r($array_name); 		  echo '</pre>'; 		} //This defines the function.array_debug($_POST[item_location]); // This calls the function.</td><td>function array_debug($array_name) { 		  echo '<pre>'; 		  ksort($array_name); 		  print_r($array_name); 		  echo '</pre>'; 		} //This defines the function.array_debug($_POST[item_rating]); // This calls the function.</td></tr>";}##write this out to the screen?><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html><head><title>Wish List Generator</title><link rel=stylesheet type="text/css" href="style.css"></head><body><H1><p><center><? echo "$_POST[wish_list_name]"; ?></p></H1><? echo "$wish_list"; ?></BODY></HTML>

You misunderstand. You must define the function before you do anything. The 'function ' statement doesn't do anything by itself. And putting it inside of a string will do even less. Place it like so:

<?function array_debug($array_name) { 		  echo '<pre>'; 		  ksort($array_name); 		  print_r($array_name); 		  echo '</pre>'; 		} //This defines the function.array_debug($_POST);?>

Then tell us what appears on the screen.EDIT: I just tried a simplified version on my server and it works fine:testforms.php

<html><body><form method="post" action="testforms2.php"><table>	<tr>		<th>Name</th>		<th>Price</th>		<th>Rating</th>	</tr>	<?php	for ($i = 0; $i < 5; $i++)	{		?>	<tr>		<td><input type="text" name="item_name[<?=$i?>]" /></td>		<td>$<input type="text" name="item_price[<?=$i?>]" /></td>		<td><select size="1" name="item_rating[<?=$i?>]">				<option>1</option>				<option>2</option>				<option>3</option>				<option>4</option>				<option>5</option>		</select></td>	</tr>		<?php	}	?>	<tr>		<td colspan="2"> </td>		<td><input type="submit" value="Test" /></td>	</tr></table></form></body></html>

testforms2.php

<html><body><pre><?php print_r($_POST); ?></pre><p> </p><p> </p><table>	<tr>		<th>Name</th>		<th>Price</th>		<th>Rating</th>	</tr>	<?php		for ($i = 0; $i < count($_POST[item_name]); $i++)		{	?>	<tr>		<td><?=$_POST[item_name][$i]?></td>		<td><?=$_POST[item_price][$i]?></td>		<td><?=$_POST[item_rating][$i]?></td>	</tr>	<?php		}	?></table></body></html>

HTML Output of testforms2.php

<html><body><pre>Array(	[item_name] => Array		(			[0] => 1			[1] => 2			[2] => 3			[3] => 4			[4] => 5		)	[item_price] => Array		(			[0] => 1			[1] => 2			[2] => 3			[3] => 4			[4] => 5		)	[item_rating] => Array		(			[0] => 1			[1] => 2			[2] => 3			[3] => 4			[4] => 5		))</pre><p> </p><p> </p><table>	<tr>		<th>Name</th>		<th>Price</th>		<th>Rating</th>	</tr>		<tr>		<td>1</td>		<td>1</td>		<td>1</td>	</tr>		<tr>		<td>2</td>		<td>2</td>		<td>2</td>	</tr>		<tr>		<td>3</td>		<td>3</td>		<td>3</td>	</tr>		<tr>		<td>4</td>		<td>4</td>		<td>4</td>	</tr>		<tr>		<td>5</td>		<td>5</td>		<td>5</td>	</tr>	</table></body></html>

Feel free to try it yourself.

That function is designed to output an entire Array.Example: 

array_debug($_SERVER);

Use it is confirm the contents of the POST or SERVER arrays to see what information is being captured by the request as a Debugging tool. Remove it from the production copy of the Code.

When you do something like this:

$wish_list .= "<tr><td align=\"center\">$_POST[item_name][$i]</td><td align=\"center\">$_POST[item_price][$i]</td><td align=\"center\">$_POST[item_location][$i]</td><td align=\"center\">$_POST[rating][$i]</td></tr>";}

You are confusing PHP. Or, more specifically, you're being ambiguous and PHP is choosing what it thinks is correct. When PHP sees this:<td align=\"center\">$_POST[rating][$i]</td>It parses it like this:<td align=\"center\">{$_POST[rating]}[{$i}]</td>and converts it to this:<td align="center">Array[0]</td>In other words, it doesn't know whether you want to print $_POST['rating'], or $_POST['rating'][$i]. In this case, it prints $_POST['rating'] (which is an array, hence the word "Array"), and then $i. This is why you need to use brackets to tell it what you mean when you embed variables in strings. Also use quotes in the array key.

$wish_list .= "<tr><td align=\"center\">{$_POST['item_name'][$i]}</td><td align=\"center\">{$_POST['item_price'][$i]}</td><td align=\"center\">{$_POST['item_location'][$i]}</td><td align=\"center\">{$_POST['rating'][$i]}</td></tr>";}

When PHP sees this:<td align=\"center\">{$_POST['rating'][$i]}</td>It's obvious what you're asking it to do, there's no more ambiguity.
