[RESOLVED] help passing an array via $_POST

[robkir]

I am building a delete module and I'm stuck. The idea is to display all the records at one time, each in a row and each row with its own submit button (it sounds screwy, but it make sense within the context of presenting the material). When the user clicks on the submit button, the form takes it to a new page, which looks at the records id number and deletes that record. The problem is I can't figure out how to pass an array via $_POST[]

Here's an abbreviate look at the code.

//loop
print "<input type='text' name='id[$i]' value='{$contact['id']}' />";
//more items to display
<td><input type='submit' name = 'choice' value='Delete Entry'/></p>\n </td></tr>";
//the user is redirected to another page which get's the id for the WHERE clause

$record_to_delete = $_POST['id'][$i];

//I've tried a dozen variations and I've looked at everything I can think of to look at, but I can't seem to find a clear explanation of how to bring an array over in a post.

Any ideas?

not 100&#37; sure i get the issue, but i think if you use print_r($_POST) on the page the form is posted to you will see the value(s) you want.

btw, $_POST is an array.

Hi robkir,

just an idea,

why dont you instead of keeping a submit button for each row , keep a check box and keep all inside a form. so this way u only need to have one submit button. make sure you name the checkbox with as array.

check out the example below,

<table width="100%" border="0">
  <tr>
    <td><form id="form1" name="form1" method="post" action="">
      <table width="100%" border="0">
        <tr>
          <td><label>
            <input type="checkbox" name="chkdel[]" value="<?=$contact['id'];?>" />
          contact one</label></td>
        </tr>
        <tr>
          <td><input type="checkbox" name="chkdel[]" value="<?=$contact['id'];?>" />
contact two</td>
        </tr>
        <tr>
          <td><input type="checkbox" name="chkdel[]" value="<?=$contact['id'];?>" />
contact three</td>
        </tr>
        <tr>
          <td><input type="checkbox" name="chkdel[]" value="<?=$contact['id'];?>" />
contact four</td>
        </tr>
        <tr>
          <td>&nbsp;</td>
        </tr>
        <tr>
          <td><input type='submit' name = 'choice' value='Delete Entry'/></td>
        </tr>

  </table>
    </form>
</td>
  </tr>
</table>

make sure each row get added dynamically with relevant contact ID.

now you can check the items you want to delete and it can be handle in php as below,

if(is_set($_POST['chkdel']) && is_array($_POST['chkdel']))
{

  while(list($key, $val)  = each($_POST['chkdel']))
  {
        $itemToDelete = $val;

  }

}

Hope this would help you.

Thanks,
Niro

Hi Niro,

I like your solution. I was trying for the individual delete button because this is for an "organization roster". Each person's position on the roster is determined by a slot number. If a person is eliminated, I wanted it to renumber the slots after the deleted party and it seemed easiest to do it one at a time--hence the individual delete buttons. But your solution will work and seems to make more sense.

Thanks. I'll put it in later tonight.

still having some problems getting it to work. I suspect I am missing some key knowledge (that's my latest excuse). Here's what I've got in the process file:

<tr>
<td><label>
<input type="checkbox" name="chkdel[$i]" value="<?=$contact['id'];?>" />
contact one</label></td>
<td><?=$contact['slot'];?></label></td>

<td><?=$contact['category'];?></td>
<td><?=$contact['position'];?></td>
<td><?=$contact['person'];?></td>
<td><?=$contact['email'];?></td>
<td><?=$contact['phone'];?></td>

  </tr>

The form action=deleteroutine.php file code is:

<?php

if(is_set($POST['chkdel']) && is_array($POST['chkdel']))
{

while(list($key, $val) = each($_POST['chkdel'][$i]))
{
$itemToDelete = $val;
print "delete " . $itemToDelete;

}

}

?>

Hi robkir,
I have attached a sample code. Hope this will give you a better understanding of the things. Please dont copy and paste the code, instead try to undestand how things are coded and if you have any queries please ask.

PS: You don`t have to have a counter for the chkdel to make it an array. If you put the name as chkdel[], when form is submitted PHP take it as an array .

Hope this will resolve your problems,

Best regards,
Niroshan

Hi Niro,

You really have a knack for making things clear. I took your rendition apart and adapted it for my own use and it works like a charm. I've learned a huge amount. Thanks for sharing. I'm about three or four months into learning the big three (PHP, SQL and HTML). I've bought three books, spent hours on the internet and I am finally getting to the point where I kind of get most things--but there's still so much to learn. This is my second full fledged program effort.

Somewhere in California, for an AYSO soccer organization, there is a comment in some code that gives you credit--it's not much of an honorific, considering virtually nobody will ever see the code except me--but at least you get some recognition.

Hope we meet again.

Cheers,

robkir
