Arrays

[agmorgan]

Good day.. I am struggling with an array which I am hoping to get some advice on.

The concept is that I show a list of items asociated with a job, using the following within a form :-

$query2 = "SELECT * FROM prepop1 WHERE PPjob='$code'";
$result2 = mysql_query($query2) or die ("Couldn't execute quer 19"); 
while ($row2 = mysql_fetch_array($result2))
{
extract($row2);

echo "<td>$PPqty </td>";
echo "<td>$PPdesc</td>";
echo "<td><input type='text' name='volume' value='$PPqty' maxlength='10' size='10'>
<input type='checkbox' name='interest[$PPcode]' value='$PPcode'>$PPcode
</td></tr>";

}

On the next page I show the choices using the the following :-

foreach ($_POST[interest] as $field => $value ) 
{
echo "$value  <br>";
}

For all of the checkbox's I chose I get the list of $PPcode no problem.

My problem is that I want to move more information per choice. for example I show a text box on the first page where I would want the ser to identfy a value, I want to show this value against the relevant choices I make.

I have tried an umber of ideas but as a result either get the word ARRAY appear OR the last number in the list. I am assuming that what I need to do is associate the Number in the text box with the array but I am buggered if I can work this bit out..

Can some one help..

cheers Andy

So you want the text-box with the name "volume" to be an array that links specific volumes to specific PPcodes? Just do what the check-box below does and make the name an array:

echo "<td><input type='text' name='volume[$PPcode]' value='$PPqty' maxlength='10' size='10'>
<input type='checkbox' name='interest[$PPcode]' value='$PPcode'>$PPcode
</td></tr>";

Then on your next page volume[XXX] will match up with interest[XXX] and volume[XXX] will have the value of $PPqty that it's supposed to.

I am still struggling with this Array problem

I have altered my page 1 script as recomended

echo "<td><input type='text' name='volume[$PPcode]' value='$PPqty' maxlength='10' size='10'>
<input type='checkbox' name='interest[$PPcode]' value='$PPcode'>$PPcode</td></tr>";

however, when I go to my page 2 and attempt to view the information I can not get the Qty to show. my script is

foreach ($POST[interest] as $field => $value )
{
echo "$field '$POST[volume]' ";

}

Well, that's because $_POST['volume'] is an array of data where the key's are $PPcode and the correlating values are $PPqty. So to get a specific one, you'd have to do:

$_POST['volume']['XXX'] (where "XXX" is some valid PPcode value).
