Re: [PHP] arrays and sessions
I've got some code and it simply isn't working. I thought it might be because each time the form submits data, the array I'm storing information in is being re-initialized. If this is the case, I don't have the multidimensional array I'm trying to get, but just a vector array with the most recent submission data. I tried making the array a session variable, but I'm not even sure the session part of it is working. So, if you have any methods that you think might work better than what I'm trying to do, I'd love to hear about it. Basically, my file is structured like this: 1. Pull in POST data, and store them in php variables 2. If the POST data is null, display the first form and get the table name, field name, field type, primary key, and null allowed information. On submit, the information is stored in an array. 3. If the POST data is not null, again display the entry form in case the user needs to add more fields, and step through the array to display the existing table info that the user has already entered. A button in a second form is also displayed. When clicked, it actually creates the table. My problems are that when I try to step through the array and display its current contents, I get index not defined errors on my for loop indices (?!). The second problem is, when I try to use the print_r function to display my array, it only displays one set of data. This might be because I'm trying to do a C++ type 2 dimensional array concept when PHP arrays are associative by nature, and I'm not sure how to get around this. Suggestions? (Yes, Kermit is my real name. Miss Piggy is well, and sends her regards.) -Kermit Chris W.

Re: [PHP] arrays and sessions
First of all, make sure you're doing session_start() before
reading/writing any session data and before you do any output.
Second, You likely need to just do something like this:
session_start();
if(post data) {
$_SESSION['formArray'][] = $_POST;
}
This will save each POST array as-is in the session.

sounds like you're just not keeping track of each iteration. i mean,
within the session variable you need to somehow differentiate between
each subsequent form submittal.
?php
$iteration = ++$_POST['iteration'];
$_SESSION['post_data'][$iteration] = $_POST;
// include $iteration in the post data
// so that next time it comes around
// it can be incremented.
echo QQQ
form method=post action=myself
...
input type=hidden name=iteration value=$iteration /
...
/form
?
you should then see a multi-dimensional array with
'print_r($_SESSION);'.
this code is untested and not very complete. ;) but maybe it will give
you some ideas?
hth,
