variables - PHP $_POST values

887

i have a little problem with storing the $_POST data, think i might be confusing myself a little.

So i have some data being posted from a loop, this data is posted as id and points, but each has a number to it so if three records are being posted we'll have

id1, id2, id3 points1, points2, points3

to collect. Now i'm using a for loop to go through the data and post it into two arrays to work with. The problem is When I want to store the data i have to use one of the names listed above ie id1 or id2. Here is my code

for($i = 0; i< $_POST['count']; i++){
    //Order input data into an array
    $inputid[$i] = $_POST['id1'];

}

Now the number part of the 'id' of the $_POST['id1'] has to be the same as $i in the for loop so it will increment as the loop does.

Thanks for the help and i hope i explained the question right.

Solution:

Why not name the inputs:name="id[1]" andname="points[1]" so you'll have$_POST['id'][...] and$_POST['points'][...] arrays to work with?

Solution:

Firstly, don't use POST variables in loops or anything else unless you've checked them out first to make sure they don't contain anything nasty.

You could try this within the loop:

$idnumber = "id" . $i;
$inputid[$i] = $_POST[$idnumber];

Solution:

Simply concatenate the string in the index:

for($i = 0; i< $_POST['count']; i++){
    //Order input data into an array
    $inputid[$i] = $_POST['id' . ($i+1)];
}

Solution:

If I understand this question, there are already a known amount of inputs that are going to be posted, so I don't understand why you need a loop at all for adding them to the array. Why not do this:

$value = array($_POST['id1'], $_POST['id2'], $_POST['id3'], $_POST['points1'], $_POST['points2'], $_POST['points3']);

than loop like this:

for(x=0;x<$value.count;x++){
    $value[x]=$value.$x;
}

That should work

Solution:

if i am not going wrong you want the posted id same as the increment var $i try this out

for($i = 0; $i< $_POST['count']; $i++){
    $post_id = 'id'.$i;
    $inputid[$i] = $_POST[$post_id];

}

Solution:

I think you can go for something like this:

for($i = 0; $i< $_POST['count']; $i++){
//Order input data into an array
$inputid[$i] = $_POST["id$i"];
}

Is this what you want?
