HTTP_POST_VARS problems

swallace

Hi,

I've got a problem getting the values out of the HTTP_POST_VARS...
On the first page I'm clicking checkboxes that have name in the following format:

name=$row[Type][$i]

where $row[Type] = mysql_fetch_array($result)

When I submit them, they are passed onto the next page, but I can't get them out...

print_r($HTTP_POST_VARS);

This leads to the following results:

Array ( [Regression] => Array ( [0] => on [1] => on [2] => on [3] => on ) [Functional] => Array ( [0] => on [1] => on ) )

If I explicitly type

echo "{$HTTP_POST_VARS['Regression'][0]}";

I get the value 'on' - super!!! But I need to do this by using variables to get the value.

eg:

//Using same query from previous page
while ($row = mysql_fetch_array($result))
{
for ($i=0; $i < $counter; $i++){
echo "{$HTTP_POST_VARS['$row[Type]'][$i]}";
}
}

Please, please, any help would be appreciated...I'm hoping that it's just the quotes I'm using or something simple

try counting the array elements, then looping that amount:

$count = $HTTP_POST_VARS['Regression'];

for($i=0; $i <$count; $i++) {

echo $HTTP_POST_VARS['Regression'][$i];

}

you could always do the same thing for the 'Regression' variable also.

Hi Stu,

cheers for the reply, but the count isn't really the problem. I can't actually get the value 'Regression' to appear...

//Using same query from previous page
while ($row = mysql_fetch_array($result))
{
for ($i=0; $i < $counter; $i++){
echo "{$HTTP_POST_VARS['$row[Type]'][$i]}";
}
}

I can't get the value from $row[Type] in the statement...this is where my hair loss is generating from...:p

What about something like this, i.e build the name up first before trying to access the HTTP_POST_VAR.

while ($row = mysql_fetch_array($result))
{
for ($i=0; $i < $counter; $i++){

$newvar = $row[Type]."[".$i."]";

echo $HTTP_POST_VARS[$newvar];
}
}

If you have any interest left after the weekend, I finally worked out the problem I had...

while( $row = mysql_fetch_array($result) ) {

for ($i=0; $i < $counter; $i++){

$newvar = ${$row[TestType]}[$i];

echo "Value of $row[TestType][$i] is $newvar<BR>";

}
}

This print out

Value of Regression[1] is on
etc

Cheers for your help Stu...
