Parsing a specific bit of a $_POST var.

iNFERiON

I am building a table that helps to maintain info in a database.
Each table row represents a row in the database.
It fetches everything OK and displays it in the rows, all good so far.
But I'm stuck at the point where I want to give users the ability to edit or delete a specific row. The rows all have their own id, specified as $num. (1st row: $num = 0, 2nd row: $num = 1; etc.).

I have this piece of code for row alteration:

	echo "\t<td><input name=\"edit[" . $num . "]\" type=\"submit\" value=\"Edit\">&nbsp;<input name=\"del[" . $num . "]\" type=\"submit\" value=\"Delete\"></td>\n";

As you can see each button also comes with it's own edit or del id. What I want to do is to have PHP check which row was selected to edit/delete, but when the form is sumbitted, $num is no longer known, since it's not a session value, but it also shouldn't be, since it changes for every row, making it a session var would always delete the last row.

How can I properly work this out so PHP recognized which "x" in $del[x] I clicked ?

U can use links:

When u generate the table u make links like:

<a href="your_edit_script.php?id={$num}">Edit</a>
<a href="your_delete_script.php?id={$num}">Delete</a>

Or if u want to use buttons then use onclick event to change the form of the action to something like:

<form action="action.php?edit=1" ..
<form action="action.php?del=1" ..

How u make it u send all the elemnts through POST u dont know on witch button u press ...

Ah yes, off course. The onclick method works.
Now got this:

	echo "\t<td><input name=\"edit[" . $num . "]\" type=\"button\" onClick=\"javascript:location.href='editproject.php?pid=" . $_GET['pid'] . "&editrow=" . $row['row'] . "';\" value=\"Edit\">&nbsp;<input name=\"del[" . $num . "]\" type=\"submit\" onClick=\"javascript:location.href='editproject.php?pid=" . $_GET['pid'] . "&delrow=" . $row['row'] . "';\" value=\"Delete\"></td>\n";

And it works just fine 🙂
Thanks.
