2 part form sending arrays

Anon

I have a 2 part form where the first part asks for how many names and addresses you'd like to add. The second part uses a for loop to make form fields where the name is an array, and the address is another array. Once the form fiends are filled in and you submit it, it's just suppose to echo the array variable values (like a receipt). I'm having trouble doing this. The trick is, is that my php server is making me use the $blah = $_POST[blah]; situation instead of just directly sending it. Here is my code...
----------------------- TEST1---

<body>
<form method=POST action=test2.php>
<input type=text size=20 name=number> NUMBER<br>
<input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2">
</form>
</body>

---------------------- TEST2---

<body>
<form method=POST action=test3.php>
<?
$number = $_POST[number];
for($count=1;$count<=$number;$count++)
{
echo "Name $count :<input type=text size=30 name=name[]><br>\n";
echo "Address $count :<input type=text size=30 name=address[]><br>\n";

}
echo "<input type=hidden value=$number name=number><br>";
?>
<input type="submit" value="Submit" name="B1"><input type="reset" value="Reset" name="B2">
</body>

------------CANNOT FIGURE OUT TEST3----

<body>
<?
$number = $POST[number];
$name = &$POST[name];
$address = &$_POST[address];

for($count=1;$count<=$number;$count++)
{
echo "<b>Name $count :</b>$name[$count]<br>";
echo "<b>Address $count :</b>$address[$count]<br>";
}
?>
</body>

If anybody could please let me know what I'm doing wrong... It'd make me oh so happy! =]

First,
« for($count=1;$count<=$number;$count++)
{
echo "Name $count :<input type=text size=30 name=name[]><br>\n";
echo "Address $count :<input type=text size=30 name=address[]><br>\n";

} »

Should be :

for($count=1;$count<=$number;$count++)
{
echo "Name $count :<input type=text size=30 name=name[$count]><br>\n";
echo "Address $count :<input type=text size=30 name=address[$count]><br>\n";

}

This would avoid eventual problems...

When you have all the datas...

$names = $POST["name"];
$addresses = $POST["address"];
for($i = 0; $i < count($names); $i++) {
if(!isset($names[$i]) || !isset($addresses[$i])) {
// code if a name or address isn't set and should be set...
break;
} else {
$current_name = $names[$i];
$current_address = $addresses[$i]
// Your code with each address...
}
}

It should work.

not finding the name or address variables. My error control message comes up "//code if name or address isn't set and should be set..."

Anon

Well, I may have made error with the name of variable while writing... $addresses could be written $adresses, ...

You must transform the code I gave you with YOUR variables names...

Anon

Forget this part :

for($count=1;$count<=$number;$count++)
{
echo "Name $count :<input type=text size=30 name=name[$count]><br>\n";
echo "Address $count :<input type=text size=30 name=address[$count]><br>\n";

}

And replace it with what you had written first...

Anon

I finally got it =P

that count() function wasn't working too well on my server so the for loop didn't know what to count up to. Instead I just send the $number var and replaced count w/ $i <= $number like so...
<?
$number = $POST["number"];
$names = $POST["name"];
$addresses = $_POST["address"];
for($i = 1; $i <= $number; $i++)
{
if(!isset($names[$i]) || !isset($addresses[$i]))
{
echo "No name or address added, go back and re-enter<br>";
break;
}
else
{
$current_name = $names[$i];
$current_address = $addresses[$i];
echo "$current_name <br>";
echo "$current_address <br>";

}

Thank you so much for the help H.L.!

You could use sizeof() instead of count. But you made something wrong :

if(!isset($names[$i]) || !isset($addresses[$i]))
{
echo "No name or address added, go back and re-enter<br>";
break;
}

If one of these variables contains "", it is set, but with not value, so you will record an empty variable !
