posting array values not working in PHP5

[dannyo101]

I have some code running on PHP4 that I moved to a new hosting account running PHP5.  I'm having an issue posting the values of my arrays after moving to PHP5.  This is the part of my code that isn't working anymore:

 

	   foreach($_POST['id'] as $t_id){
	  $suid=$_POST['suid'][$t_id];
	  $uname=$_POST['uname'][$t_id];
	  $desc=$_POST['desc'][$t_id];
	  $nw_role=$_POST['nw_role'][$t_id];
	  $df_start_dt=$_POST['df_start_dt'][$t_id];
	  $df_end_dt=$_POST['df_end_dt'][$t_id];
   }

 

If I try to output one of the variables, I'm not seeing any values.

 

echo $uname[1];

Show us your form that sends to this script..

Also try a var_dump on $uname

var_dump($uname);

thanks...here's the form blow.  the var_dump produces NULL:

 

   <?php
   echo '
   <form name="users" method="post" action="'.$_SERVER['PHP_SELF'].'">
   <table width="100%" border="0">
      <tr>';
     if ($pgaction=='add') {
	 echo '<td><input type="submit" name="submit_a" value="Add Record" style="height: 25px; width: 100px">
	 							   
         					   <input type="submit" name="reset" value="Cancel" style="height: 25px; width: 100px"></td>';
}
if ($pgaction=='edit') {
	 echo '<td><input type="submit" name="submit_e" value="Apply" style="height: 25px; width: 100px">
	 							   
            					<input type="submit" name="reset" value="Cancel" style="height: 25px; width: 100px"></td>';
}
    if (($pgaction<>'add')&&($pgaction<>'edit')) {

What happens if you output the whole $_POST variable?

[wildteen88]

Looking at your form you don't have a field named id, but you do have a form field named suid. SO may maybe you meant to use $_POST['suid'] instead of $_POST['id']

 

Check how _POST is formatted using

echo '<pre>'.print_r($_POST, true).'</pre>';

[dannyo101]

I changed the code to use $_POST['suid'] instead of $_POST['id'], but something still isn't right...

 

Here is how the _POST is formatted:

Array
(
    [submit_e] => Apply
    [suid] => Array
        (
            [1] => 1
            [2] => 2
            [3] => 3
            [4] => 4
            [5] => 5
        )

    [uname] => Array
        (
            [1] => gen.us3r!
            [2] => admin!2009
            [3] => wfgc
            [4] => shelterharbor
            [5] => concordcc
        )

    [desc] => Array
        (
            [1] => User Login1
            [2] => Administrator Login
            [3] => User Login
            [4] => User Login
            [5] => User Login
        )

    [nw_role] => Array
        (
            [1] => user
            [2] => admin
            [3] => user
            [4] => user
            [5] => user
        )

    [df_start_dt] => Array
        (
            [1] => 10/20/2009
            [2] => 10/20/2009
            [3] => 01/11/2010
            [4] => 01/10/2010
            [5] => 01/11/2010
        )

    [df_end_dt] => Array
        (
            [1] => 11/30/2010
            [2] => 10/20/2010
            [3] => 01/11/2011
            [4] => 03/01/2010
            [5] => 03/01/2010
        )

)

 

When I print each value of the array, it seems to be breaking up the word into separate elements.  For example:

 

echo $uname[1] produces 'o'

echo $uname[2] produces 'n'

echo $uname[3] produces 'c'

echo $uname[4] produces 'o'

 

The code works fine in PHP4 for me, which is why I'm having some trouble figuring this out.

[Buddski]

Its outputting that because of the way you are assigning $uname.

You are assigning it the actual value.. if you were to echo $uname; it will display the LAST uname iteration because you are overwriting the variable within the foreach loop..

 

What you are wanting to do is..

foreach($_POST as $key=>$value){
$$key = $value;
}

Now you can access all the variables with, for example,

 echo $uname[1];

yes, thanks that seems to work; however, how do I assign the key in the array to be the id of the database record?  In my example, the ids are sequential 1,2,3,4 so everything works fine..  But what if I have 4 rows, with ids 1, 5, 7, and 8 and want to assign the values of the array to those keys?

[dannyo101]

sorry, please disregard that last post.  everything is working as expected.  thanks for your time and help with this issue.
